[InstCombine] Remove support for volatile in phi of load transform (#193154)
The volatile support does not have test coverage, and dates back to when
this transform was originally introduced 20 years ago, so it does not
appear that volatile support was specifically added -- it was just
naively implemented to start with, and then received bug fixes.
The current implementation is still buggy, e.g. it allows sinking
volatile past inaccessiblemem calls, which is invalid (as those may
contain volatile accesses on allocas).
After https://github.com/llvm/llvm-project/pull/192992, there would be
another constraint that all the instructions after the volatile load are
speculatable.
This wouldn't be hard to fix, but I'd rather remove volatile support
here entirely.

These two functions, which are the entry points into the framework-

functions. Move them to immediately after the visitor classes that they
rely on. Hopefully that will prevent them from drifting into obscure
places again.

[Flang] Add SIMD Compiler Directive (#192969)
Similar to #192674, this adds support for the SIMD Compiler Directive,
previously supported by legacy Fortran frontends such as classic-flang.
This operates in the same way as `VECTORALWAYS`, marking a DO loop to be
vectorised by the LLVM Backend.
The missing support was highlighted while building an opensource
benchmark, as build warnings were indicating that this compiler
directive was being ignored.

[bolt] AArch64: Fix TLSDESC to LE relaxation by mold (#190370)
mold linker creates relaxation stub from TLSDESC to LE, (lld makes it
IE) using sequence as NOP+NOP+MOVZ+MOVK. This in itself is not an issue,
when --emit-relocs is added the relocs R_AARCH64_TLSDESC_ADD_LO12 and
R_AARCH64_TLSDESC_CALL are associated with useful MOVW instructions.
However bolt does not check for R_AARCH64_TLSDESC_ADD_LO12 in
adjustRelocation() when disassembling the file. This later triggers a
bug when reloc is patched as movk is patched with S_LO12 fixup kind
which is invalid.
Refer to bug: https://github.com/llvm/llvm-project/issues/190366 for
details.

[SPIRV] Fix legalization of zero-sized intrinsic globals (#192730)
Some LLVM global intrinsics like `llvm.global_ctors` may become
zero-sized arrays if all constructors are inlined/optimized out.
These variables use appending linkage, which is only valid on arrays,
however as we are lowing to a pointer, this causes invalid IR if we
maintain the same linkage.
Use `ExternalWeak` linkage, the only other mergable linking type allowed
for intrinsic global variables with definitions. We also need to not
specify an initializer to not produce an invalid module.
As these variables do not represent user visible code, and all entries
were optimized out anyway, the new linkage should be fine.

[MachineCopyPropagation][NFC] Refactor EliminateSpillageCopies (#192609)
This patch builds on the original implementation to address areas that
may impact compile time regression if enabled. The aim of the patch is
to streamline and improve the implementation for better compile time
impact. A summary of the changes is as follows:
- Cost modelling that does an initial scan of the block, any blocks with
less than 6 copies are immediately skipped.
- RegMask scan in `findLastSeenDefInCopy` removed. This now only checks
the recorded copies to ensure that RegMasks are clobbered when they are
seen if they clobber a Reg
- Streamlining of `IsSpillReloadPair` and `IsChainedCopy` to reduce the
need for a second call to isCopyInstr to get the DestSourcePair, these
are now returned from the lamdba function
- Use of TRI API to get the CommonRegClass

[DAG] visitFREEZE - revisit frozen node after merging with unfrozen uses (#188206)
After merging other uses of a N to all use FREEZE(N), make sure we
revisit FREEZE(N) to attempt to push the FREEZE through the (now
hasOneUse()) operand.
The only remaining annoyance I can find is the freeze nodes interfering
with amdgpu scalar/vector instructions - mainly because we end up with
more freeze(vectorload) patterns and extract_vector_elt nodes can't peek
through anymore - this is an ongoing general problem that nobody has
found a good answer to yet.

Follow up to #192965.
This call adds a newline if there isn't one. Changing these will
eventually let us always add a newline, which is in line with
the other methods on CommandReturnObject.
This is a small part of calls found with:
* VSCode search for
`(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\\n"` and
replace with `$1"`.
* Asserting that the last character of the format string is not a
newline.

[RISCV] Functional llvm.vector.reduce.mul on scalable types (#193094)
RVV does not have an instruction for performing a horizontal multiply
reduction (either integer or floating point). However, a user of clang
can explicitly write at least the integer form via the
__builtin_reduce_mul construct, and currently we just crash when
compiling this.
This change converts the crash into functionally correct scalar loop to
process each element one by one at runtime. This will be slow, but at
least correct.
Note that to my knowledge we can't generate the floating point one
directly from C, but I decided to handle both for completeness while I
was here.
Written by Claude Code with guidance and review by me.

[libc] Add struct sockaddr_storage (on linux) (#192978)
This deceptively simple patch has one catch. The POSIX standard states:
"""
When a pointer to a sockaddr_storage structure is converted to a pointer
to a sockaddr structure, or vice versa, the ss_family member of the
sockaddr_storage structure shall map onto the sa_family member of the
sockaddr structure. When a pointer to a sockaddr_storage structure is
converted to a pointer to a protocol-specific address structure, or vice
versa, the ss_family member shall map onto a member of that structure
that is of type sa_family_t that identifies the protocol's address
family. When a pointer to a sockaddr structure is converted to a pointer
to a protocol-specific address structure, or vice versa, the sa_family
member shall map onto a member of that structure that is of type
sa_family_t that identifies the protocol's address family. Additionally,
the structures shall be defined in such a way that the compiler treats
an access to the stored value of the sa_family_t member of any of these
structures, via an lvalue expression whose type involves any other one
of these structures, as permissible, despite the more restrictive
expression rules on stored value access as stated in the ISO C standard.
...
Note that defining the sockaddr_storage and sockaddr structures using
only mechanisms defined in early editions of the ISO C standard may
produce aliasing diagnostics when applications use casting between
pointers to the various socket address structures. Because of the large
body of existing code utilizing sockets in a way that could trigger
undefined behavior due to strict aliasing rules, this standard mandates
that these structures can alias each other for accessing the sa_family_t
member of the structures (or other members for protocol-specific
structure references), so as to preserve well-defined semantics. An
implementation's header files may need to use anonymous unions, or even
an implementation-specific extension, to comply with the requirements of
this standard.
"""
To satisfy this requirement I add the may_alias attribute on all the
sockaddr structures.

[mlir] targeted verification for transform "inlining" (#192956)
When merging named transform sequences into their include locations,
rely on the InlinerDialectInterface implementation newly added to the
transform dialect instead of the full verification after the fact. This
enables us to only verify aspects of the IR that may change in a way
compatible with the rest of the infra, reducing the overall cost of the
process.
Use `LogicalResult` as appropriate instead of returning dummy
`InFlightDiagnostic` while I'm here.

[ItaniumDemangle] Strip __alloc_token_ to transparently demangle allocation functions (#191048)
Update the Itanium demangler to recognize and strip `__alloc_token_`
prefixes introduced by AllocToken instrumentation [1]. This ensures that
instrumented allocation functions (e.g., `__alloc_token__Znwm`) demangle
back to their original source-level names (e.g., `operator new(unsigned
long)`) with a suffix `(.alloc_token)` indicating their non-standard
origin.
Since AllocToken is intended to be transparent to users who continue to
use `operator new` as before, the demangled name should reflect this
reality instead of confusing users with internal instrumentation names
in stack traces or symbolization output.
Synchronize changes across llvm and libcxxabi copies.

[OpenMP][OMPIRBuilder] Support complex types in atomic update/capture (#191490)
Route struct-typed values through the libcall path in
`emitAtomicUpdate`.
Previously, the libcall path was gated on `RMWOp == BAD_BINOP`, so
atomic capture swap patterns (`v = x; x = expr`) for complex values
lowered as structs fell through to the cmpxchg path. That path called
`getScalarSizeInBits()` on a struct type, produced 0, and triggered an
assertion in `IntegerType::get()`.
Remove the `BAD_BINOP` restriction so struct types always use the
libcall path. This is safe because the libcall path does not use `RMWOp`
and already handles arbitrary type sizes correctly.
Also fix `LoadSize` in the libcall path to use `XElemTy` rather than the
pointer type, which previously gave the wrong size for larger complex
types such as `complex(8)`.

[profcheck] Fix assert in getInitializer call on global with no initializer (#193514)
This code calls `getInitializer` without checking if the global has an
initializer, which causes an assert if there isn't one. These globals
may have no initializer after optimization from `globalopt`.
Check for an initializer first.
This is already locked down with
`CodeGen/SPIRV/legalize-zero-size-arrays-appending.ll` so we don't need
a new test.

[Support][JSON] Use `std::unordered_map` for object storage (#171230)
`llvm::DenseMap` is not suitable for the key-value `Storage` inside
`llvm::json::Object`. Use `std::unordered_map` instead to optimize
memory usage.
`llvm::DenseMap` is optimized for mapping small keys and values
(pointers), and it pre-allocates 64 buckets by default.
`llvm::json::ObjectKey` is 24 bytes in size, and `llvm::json::Value` is
40 bytes. Currently, the JSON parser allocates 4KB of memory for each
JSON object. In practice, most JSON objects contain only a handful of
fields, and likely to have lists of many small objects. This is a
significant waste of memory.

[lldb] Decorate tests that use threading (#193117)
Add a new decorator `skipIfTargetDoesNotSupportThreads` to skip tests
that use threading. This is motivated by running the test suite
targeting WebAssembly, where `wasip1` does not support threads. There
are variants that do support threading (e.g. `wasip1-threading`) that
the current implementation accounts for.

This narrows `FindSymbolsWithNameAndType` calls from searching all

CoreFoundation, libBacktraceRecording.dylib).
The arclite fallback in `CalculateHasNewLiteralsAndIndexing` still
searches all images because libarclite is a static library linked into
the main executable.

For scalable vectors, pass the maximum runtime step to

the original trip count directly, if MaxRuntimeSteps divides the
original trip count without remainder.
In those cases, all lower power-of-2 vscales will divide the rip count
without remainder.

Reland: [MemProf] Dump inline call stacks as optimization remarks (#193545)
This iteration limits the test case to x86_64-linux to prevent bot
failures.
---
This patch teaches the MemProf matching pass to dump inline call
stacks as analysis remarks like so:
frame: 704e4117e6a62739 main:10:5
frame: 273929e54b9f1234 foo:2:12
inline call stack: 704e4117e6a62739,273929e54b9f1234
The output consists of two types of remarks:
- "frame": Acts as a dictionary mapping a unique MD5-based FrameID
to source information (function name, line offset, and column).
- "inline call stack": Provides the full call stack for a call site
as a sequence of FrameIDs.
Both types of remarks are deduplicated to reduce the output size.
This patch is intended to be a debugging aid.

[CIR] Support guard COMDAT for weak linkage in LoweringPrepare (#193274)
Static locals inside inline functions get `linkonce_odr` linkage, and
their guard variables need their own COMDAT groups so the linker can
deduplicate them across TUs. We were hitting an NYI error for this case
in `LoweringPrepare`.
The fix is straightforward: set `guard.setComdat(true)`, which makes
`LowerToLLVM` create a per-symbol COMDAT selector — the same thing
classic codegen does at `ItaniumCXXABI.cpp:2798`.
I ran into this while trying to compile the Bullet physics engine
through CIR. Functions like `btMatrix3x3::getIdentity()` use this
pattern (return a reference to a function-local static from an inline
member function), and 6 of the 121 source files were failing because of
it. With this fix, all 121 compile cleanly.

Replace it with a hasOneUse() fast path plus a check that bails only when I
has a user outside the grandparent PHI's Scalars. Uses within the same
vectorized PHI are tracked by the existing dep machinery; an external user
(e.g. a scalar PHI in a different block) is what trips scheduleBlock's
"must be scheduled at this point" assertion.
Fixes #193315.

[CIR] Fix lowering of strings in constant array attributes (#193553)
There was code in the CIR CXXABILowering pass that was assuming
ConstArrayAttr::getElts() would return an ArrayAttr. This isn't true in
the case of string constants with trailing zeros, so we had a crash in a
mlir::cast<> call. The problem only appeared when a string array
appeared in the same initializer as a type that required CXXABI-specific
lowering, such as a member pointer.
This change fixes the CXXABILowering to simply keep the existing string
attribute, which is known to be legal for the purposes of that pass.

[flang][OpenMP] Support user-defined declare reduction with derived types (#190288)
Fix lowering of `!$omp declare reduction` for intrinsic operators
applied
to user-defined derived types (e.g., `+` on `type(t)`). Previously, this
hit a TODO in `ReductionProcessor::getReductionInitValue` because the
code
tried to compute an init value for a non-predefined type, when it should
instead use the initializer region from the `DeclareReductionOp`.
This fixes the issue #176278: [Flang][OpenMP] Compilation error when
type-list in declare reduction directive is derived type name.
The root cause was a naming mismatch: `genOMP` for
`OpenMPDeclareReductionConstruct` used a raw operator string (e.g.,
"Add")
as the reduction name, while `processReductionArguments` at the use site
computed a canonical name via `getReductionName` (e.g.,
"add_reduction_byref_rec__QFTt"). The `lookupSymbol` in
`createDeclareReductionHelper` never found the already-created op, so it
fell through to `createDeclareReduction` which called
`getReductionInitValue` with the derived type and hit the TODO.
The fix has four parts:
1. Consistent names: In `genOMP` for `OpenMPDeclareReductionConstruct`,
compute the reduction name using the same `getReductionName` scheme that
`processReductionArguments` uses, so both sites produce identical symbol
names. For intrinsic operators, this maps through `ReductionIdentifier`
to
get the canonical name. For user-defined named reductions, the raw
symbol
name is used directly, matching the existing custom-reduction lookup
path.
2. Reuse reduction: In `processReductionArguments`, when an intrinsic
operator reduction is requested, check whether a user-defined declare
reduction already exists under that canonical name before attempting to
create a new one. If found, reuse it. This avoids calling
`createDeclareReduction` (and thus `getReductionInitValue`) for types
that
have user-provided initializers.
3. Reference semantics: Change `doReductionByRef` to return true for
derived types. Previously it returned false for both trivial and derived
types, treating derived types as by-val. This is incorrect for
user-defined combiners that operate on components via side-effects
(e.g.,
`omp_out%x = omp_out%x + omp_in%x`): the combiner mutates `omp_out` in
place and does not produce a whole-struct value, so `convertExprToValue`
returns the component type (`i32`) rather than the struct type, causing
a
type mismatch in the `omp.yield`. By-ref is the correct model: the
combiner stores into the lhs reference and yields it.
The combiner callback in `processReductionCombiner` is also updated to
handle the by-ref derived-type case: when the combiner result type does
not match the element type (as happens with component-level
assignments),
the store is skipped since the assignment already wrote into omp_out as
a
side-effect, and only the lhs reference is yielded.
4. GPU codegen for non-descriptor by-ref reductions: The GPU reduction
codegen in OMPIRBuilder unconditionally called the `DataPtrPtrGen`
callback for all by-ref elements, assuming descriptor-based pointer
indirection was always needed. For simple derived types (e.g., a struct
with scalar integer members), there is no Fortran descriptor/box, so
`dataPtrPtrRegion` is empty and `DataPtrPtrGen` is null. This caused a
`std::bad_function_call` crash (or an assertion failure in
`getSingleElement` when the empty region was inlined).
The fix returns a null `DataPtrPtrGen` callback from `makeRefDataPtrGen`
when `dataPtrPtrRegion` is empty, and guards all call sites in
OMPIRBuilder to skip descriptor indirection when `DataPtrPtrGen` is
null.
For non-descriptor by-ref reductions, the pointer already references the
data directly--no indirection is needed.
Tests:
- Update declare-reduction-intrinsic-op.f90 from a negative test
(checking for the TODO error) to a positive test checking generated
MLIR.
- Update omp-declare-reduction-derivedtype.f90 CHECK lines to match the
reference semantics fix.
- Add declare-reduction-finalizer.f90 for derived type with init and
finalization.
Remaining work: declare reduction without an initializer clause is not
yet
supported.

[Clang][AST] Introduce `ExplicitInstantiationDecl` to preserve source info and fix diagnostic locations (#191658)
This is the initial fix of
https://github.com/llvm/llvm-project/issues/191442. Following the
discussion here
https://github.com/llvm/llvm-project/issues/115418#issuecomment-2467017012.
- Fix #21040
- Fix #52659
- Fix #115418
- Fix #14230
- Fix #21133
### Description
This PR introduces a new AST node, `ExplicitInstantiationDecl`, to
systematically fix the long-standing issue of missing or incorrect
source location information for explicit template instantiations.
#### Background & The Problem
Historically, Clang's AST lacked a dedicated node to represent the
lexical occurrence of an explicit instantiation statement. Instead,
`Sema` tried to shoehorn this information into existing specialization
nodes (e.g., `FunctionDecl`, `VarTemplateSpecializationDecl`) or simply
returned `nullptr`.
This resulted in fragmented behavior across the seven instantiable
entity types:
* Function & Member Function Templates: Returned `nullptr`, completely
losing `SourceRange` and `NestedNameSpecifier` information.
* Member Functions & Static Data Members: Mutated existing nodes
in-place. Consequently, multiple `template` or `extern template`
declarations in the same file would overwrite each other's source
locations.
* Variable Templates: Suffered from `dyn_cast` bugs and dropped NNS
information.
#### Design Trade-offs Evaluated
Before settling on the current design, I evaluated a mixed
redeclaration-chain approach (similar to how explicit *specializations*
are handled, creating new `FunctionDecl` nodes and stitching them into
the redecl chain). However, this approach had significant flaws:
1. Inconsistency: It couldn't be cleanly applied to member functions or
static data members due to `DeclContext` constraints (e.g., a member
function shouldn't lexically reside in a namespace `DeclContext`, but
placing it in the class context would pollute member lookup).
2. Fragility: It required bypassing standard `FoldingSet` mechanisms
(`setFunctionTemplateSpecialization`).
3. Lookup Pollution: Injecting new `NamedDecl` nodes purely for
instantiations risked breaking downstream `ASTMatcher`s and altering
name lookup behavior.
To avoid these pitfalls, this PR introduces `ExplicitInstantiationDecl`
as a **purely lexical annotation node**.
**Key Design Characteristics:**
1. Inherits from `Decl`, not `NamedDecl`: This is the most crucial
design choice. Much like `StaticAssertDecl` or `FriendDecl`, this node
lives in a `DeclContext` (making it traversable by `RecursiveASTVisitor`
and visible in AST dumps) but remains completely invisible to C++ name
lookup. It does not interfere with overload resolution or lookup tables.
2. Unified Representation: A single node type now covers all seven
entity types. It holds a pointer (`Specialization`) to the underlying
instantiated declaration, unifying how functions, variables, classes,
and members are handled.
3. Lexical Fidelity: The node resides in the enclosing namespace or
Translation Unit where the explicit instantiation was actually written,
perfectly preserving the `SourceRange`, `NestedNameSpecifierLoc`, and
the exact locations of the `template` and `extern` keywords.

definition diagnostics to check across ModuleMaps in a very specific
case. The check proved to be overly strict. This PR makes sure we do not
check when the `Existing` module's definition location is unknown. Such
cases are only observed when a module built through include-tree (CAS)

Such cases are only present when CAS is used, so no test case is

[HLSL] Reuse temporaries of aggregate types in list initialization (#191605)
When aggregate types appear as _prvalues_ in HLSL initializer lists, convert them to _xvalues_ and wrap them in `OpaqueValueExpr` so the temporaries can be reused across all element accesses. This allows code generation to avoid emitting redundant copies of the same aggregate temporary.
This should be especially helpful once support for constructors on user-defined structs is removed, and initializer lists will be the primary mechanism for struct initialization.
A similar optimization may also be applicable to vector and matrix types. However, their current code generation path does not yet support handling `OpaqueValueExpr` in initializer lists.

[BOLT] Fix null pointer dereference in DWP processing with split DWARF (#191474)
Fix two null pointer dereferences in BOLT's DWP processing path that
cause SIGSEGV in worker threads when -update-debug-sections is used with
a co-located .dwp file.
1. getSliceData() in updateDebugData() dereferences the result of
getContribution() without checking for null. getContribution() returns
nullptr when the requested section kind (e.g. DW_SECT_LINE) is not
present as a column in the DWP CU index. When BOLT processes a DWP where
certain section kinds are absent from the index, every worker thread
that hits this path crashes simultaneously.
2. processSplitCU() dereferences getUnitDIEbyUnit() without checking for
null. If buildDWOUnit() fails for a CU, the returned DIE* is null and
the dereference crashes.
Crash signature from dmesg:
```
llvm-worker-*: segfault at 8 ip <offset> error 4 in llvm-bolt
(multiple worker threads crash at the same instruction)
```
The faulting address 0x8 corresponds to accessing the Length field
(offset 8) of a null `DWARFUnitIndex::Entry::SectionContribution*`.
At Meta, I reproduced this building hhvm with a co-located .dwp file and
the flags `update-debug-sections -debug-thread-count=80 -lite=0` with
profile data.
I confirmed that the unfixed BOLT crashes deterministically whereas the

[CIR] Fix a dangling reference to a replaced global (#193561)
We had a bug in CIR where we were replacing a global value that was
being used to track the insertion location of the last global created.
When we erased this value while still holding a reference to it, it
caused subsequent globals to be created in a detatched state, which in
turn led to crashes when lowering uses of those globals to the LLVM
dialect.
This change updates `lastGlobalOp` when the global it is referencing is
replaced.

[flang] Fix inline transfer for unsigned integer types (#193570)
Fix a crash when transfer is used with Fortran unsigned types. The
arith.bitcast op requires signless integer or float operands, but the
inline optimization was applying it to unsigned integer types (ui32),
causing a verification failure. Changed the guard from
mlir::isa<mlir::IntegerType> to isSignlessIntOrFloat() so unsigned
integer transfers fall through to the address-level fir.convert path
instead.
This is to fix a regression reported here:

AMDGPU: Skip last corrections in afn f64 reciprocal (#183696)
Device libs has a fast reciprocal macro that is close

compared to the full division.
The basic reciprocal handling has identical output to this
macro. The negative reciprocal case has different fneg placement
and smaller code size, but I believe should be the same.

[lldb] Fix empty backtraces for scripted threads with no artificial frames (#193387)
Following 86aa43999bec, `ScriptedThread::LoadArtificialStackFrames`
unconditionally calls `SetAllFramesFetched` even when the scripted
thread provided zero artificial stack frames via `get_stackframes`.
This prevents the normal unwinder from creating frames from the register
context, leaving `m_frames` empty. When GetFrameAtIndex(0) is
subsequently called, it triggered the follow on assertion builds:
```
assert(!m_thread.IsValid() && "A valid thread has no frames.")
```
This affects scripted threads that provide register context via
`get_register_context` but rely on the unwinder for frame creation
rather than overriding `get_stackframes`.
This patch fixes the issue by returning early in
`LoadArtificialStackFrames` in case the scripted thread StackFrame array
is empty, preventing it from calling `SetAllFramesFetched` on it's
StackFrameList.

[SLP]Fix dominance for multi-use copyable scalars in scheduled bundle
scheduleBlock skips copyable bundle members with their own ScheduleData,
leaving them at their original position. If such a scalar comes after
MainOp and satisfies doesNotNeedToBeScheduled, the vectorized op is
inserted at LastScheduledInst while the scalar stays behind, so the
insertelement feeding the copyable lane fails to be dominated by it.
After placing bundle members, move copyable scalars with more than one
use (same block as MainOp, doesNotNeedToBeScheduled, schedulable from
the tree entry's view) to just before LastScheduledInst.
Fixes #193513.

Ensure that the Synthetic children of a ValueObject are managed by their parents ClusterManager (#192561)
A very common pattern in our synthetic child providers was to make the
child ValueObject using ValueObjectConstResult::Create or some form of
the static ValueObject::CreateValueObjectFrom*** methods, and store and
hand that out as the child. Doing that creates a "root" ValueObject
whose lifecycle is not linked to the lifecycle of the ValueObject it is
a child of. And that means it is possible that either the child or the
parent could have gotten destroyed when the other ValueObject gets asked
a question about it.
For the most part this doesn't happen because there are usually enough
other shared pointer references binding the two to keep both sides
alive. But we have gotten a small but steady stream of reports for years
now of crashes where a ValueObject accesses its ClusterManager but that
has already been deleted. I've never been able to find a reproducible
case of this, but one plausible cause is that we are violating the
contract that "all the children of a ValueObject have coterminous
lifespans, enforced by the ClusterManager". So it is unsurprising that
they might sometimes not stay alive as long as they should.
This patch addresses that by providing a way to use these static create
methods but passing in the ClusterManager to be used, and adds or
modifies where extant the CreateChildValueObjectFrom*** methods to pass
in the parent manager.
This patch is not complete. It turns out that routing the ClusterManager
from CreateValueObjectFromExpression all the way to where the expression
result VO is made is quite intrusive, and would have made this already
quite large (though largly mechanical) patch become unweildy. Since I am
mostly concerned about synthetic child providers, and we discourage
using expressions for them, I think that's an acceptable separation.
I also added a test where the ValueObjectSynthetic hands out its
children, checking whether the child being handed out is in fact owned
by the parent handing it out. It is controlled by a setting
(target.check-vo-ownership) which is currently off by default - since I
can't provide a way to do this correctly for expressions yet. But I turn
it on in the testsuite. That's the real testing strategy for this patch,
since its goal is to ensure that all the children we hand out are
managed by their parents. I didn't put an equivalent check in
ValueObjectVariable because that system really doesn't allow a way to do
this incorrectly.
I also fixed some of the tests that were making children using
CreateValueObjectFromExpression to make their children with
CreateValueObjectFromData instead. I could have opted the tests out of
the check, but using the expression parser to do this work is not best
practice, so I didn't want to leave bad examples around. I left one case
that does do it with expressions, however, so we still have a test for
that not-recommended but people do it anyway path.

[SPIR-V] Handle ASM with multiple outputs (#187128)
Inline ASM that writes to multiple registers is represented as a struct
returning call in LLVM IR. We did not handle this properly, as we
mutated the callsite, but did not correctly retrieve the type during
lowering to SPIR-V. Furthermore, IRTranslator tries to do some clever
things when lowering ASM, which are completely unhelpful to SPIR-V,
which merely wants to pass the original ASM through. This patch
correctly retains the IR type and cleans up the IRTranslator introduced
noise, matching how the SPIRV-LLVM Translator would handle such cases.
There is probably a cleaner reformulation of this to be had when we
rework the entire callsite mutation infra.

I had a failing test case where the log file contains the string being

truncated. I have not debugged why. As soon as I saw the issue, I
figured it was best to skip all the intermediaries, and pass the log

[libc][CndVar] reimplmement conditional variable with FIFO ordering (#192748)
This PR reimplements conditional variable with two different variants:
- futex-based shared condvar with atomic counter for waiters
- queue-based private condvar
Notice that thread-local queue node cannot be reliably accessed in
shared processes, so we cannot use a unified implementation in this
case.
POSIX.1-2024 (Issue 8) added atomicity conditions to conditional
variable:
- The `pthread_cond_broadcast()` function shall, **as a single atomic
operation**, determine which threads, if any, are blocked on the
specified condition variable cond and unblock all of these threads.
- The `pthread_cond_signal()` function shall, as a **single atomic
operation**, determine which threads, if any, are blocked on the
specified condition variable cond and unblock at least one of these
threads.
This means that threads parked after a condvar signal event shall not
steal signals before it. From my read, both implementation fulfills the
requirement but glibc claims that single futex does not provide the
stronger ordering needed by its users hence switched to a rotational
queue, to fulfill the requirements mentioned in
https://sourceware.org/bugzilla/show_bug.cgi?id=13165. As in a single
futex, the lock acquisition do not happen in order and hence when a
spurious wakeup happen, later waiters may "steal" the signal. However
musl's shared implementation and bionic's whole implementation and
Rust's std condvar still stick to a signal-futex+accounting data style.
Musl's private condvar and this implementation are even stronger in the
sense that not only the queue is decided as an atomic event, the mutex
acquisition also happens in baton-passing style.
Our implementation is different from musl in the sense that we have done
some spin attempts instead of always do futex syscall to requeue threads
(with a new requeued state added). This gives a chance for the
signal/waiter to stay in fast path if the queue is really small. Based
on the microbenchmark, this implementation is generally more performant.
We also abuse the `RawMutex`'s LOCKED state as "waiting for its turn".
One caveat we can see from the benchmark
(https://github.com/SchrodingerZhu/condvar-benchmark) is that strict
FIFO condvar is not that good if users are maintain the order on
themselves as in `turn_ring`, because many threads may just wake up
first only see it is not its turn while blocking the real thread in
turn. However, a semaphore or other synchronization primitives would be
more suitable in those cases. Even though in benchmark like
`turn_ring/broadcast_stress` made this code perform badly (but still
similar to musl anyway), they are not really the correct usage. In other
cases, we are always close to the fastest while providing a stronger
FIFO semantic.
TODO in future commit:
- support pthread cancellation. Ideally we should block cancellation
when signal is consumed and add cancellation callback for checking
illegibility.
- think about stronger ordering semantic in shared case (?)

[lldb/test] Fix shared library symlinks for remote testing (#189177)
When running tests on a remote device, framework convenience symlinks
created by test Makefiles (e.g. `$(BUILDDIR)/Framework` pointing to
`$(BUILDDIR)/Framework.framework/Framework`) cause launch failures.
`Platform::Install` recreates these as symlinks on the remote device
pointing to host build paths that don't exist, resulting in "No such
file or directory" from dyld.
This patch changes `LN_SF` in Makefile.rules to strip the common
directory prefix from the symlink source using `patsubst` so it produces
relative symlinks instead of absolute ones.
It also resolve symlinks with `os.path.realpath()` in
`registerSharedLibrariesWithTarget` before registering modules so that
`Platform::Install` sees a regular file and transfers the actual binary
content.

[ELF] Handle INCLUDE like a call stack (#193427)
The lexer maintains a stack of buffers, which allows a construct
started in an INCLUDE'd file to be closed by the parent. This produces
spurious acceptance of malformed scripts (e.g. a bare assignment with
no trailing `;` in the include, terminated by the parent's `;` after
`INCLUDE`) and undefined-behavior span computations in
`readAssignment`'s `commandString` (issue #190376).
Force each INCLUDE to fully parse its own content, similar to a call
stack frame. `ScriptLexer::lex` no longer auto-pops on EOF; the
`buffers` member is gone. `readInclude` takes a `function_ref<void()>`
callback, and the four call sites (top-level, SECTIONS, output
section, MEMORY) pass a context-appropriate parser.
With this, each buffer contains complete parser structures by
construction, so the `[oldS, curTok)` pointer range in
`readAssignment` no longer needs a guard.

[ScheduleDAG] Avoid duplicate worklist entries in ComputeDepth/ComputeHeight. NFC (#192023)
The old loop pushed every not-current predecessor in one sweep, so on
diamond-shaped DAGs a predecessor could be pushed while still on the
stack. Measured on clang -O2 -c sqlite3.i with the old algorithm
instrumented: ComputeDepth had 10.8% duplicate pushes (21.4% of calls
hit the issue).
Rewrite as an iterative post-order DFS that pushes one predecessor at a
time and breaks.

[WebAssembly] Fix wide bitmask fallback in performBitcastCombine (#190915)
The wide <N x i1> -> iN fallback in performBitcastCombine hardcoded
v16i1/i16 partial masks for every chunk. That is only valid for
16-lane chunks and can crash for cases such as v32i16, where each
concat operand is v8i16 and the partial mask should be v8i1/i8.
Derive the per-chunk mask and integer types from the actual concat
operand type when reconstructing the final scalar bitmask.

Its looks like you're adding new instrumentation/entry points to ASAN -

[clang][modules-driver] Add support for C++ named modules and `import std` (#193312)
This patch adds basic support for explicit C++ named module builds,
managed natively by the Clang driver, including support for use of the
Standard library modules.
This follows #187606, which adds the same for Clang modules.
Current limitations:
- Standard library modules are still compiled to object files instead of
using the provided shared library. (This will be addressed in a
follow-up soon.)
- Caching is not supported yet (but likely to be added during the
upcoming GSoC cycle).
- Importing C++ standard library modules into Clang modules is not
supported (and not expected in the near term).

However some of operators are split and some are scalarized depends on
operator type, in this case we need to split it manually.

[RISCV][MC] Remove tautological CHECK-UNKNOWN disassembly checks (NFC) (#193682)
Many RISC-V MC tests assemble with `--mattr=+v` (or another extension),
then run llvm-objdump on the result *without* `--mattr=`, expecting the
disassembler to print `<unknown>` for every instruction. These
CHECK-UNKNOWN lines only restate the encoded bytes that are already
verified by CHECK-ENCODING from `llvm-mc -show-encoding`, so they do not
add coverage.
Drop the CHECK-UNKNOWN RUN lines and check directives from the affected
tests to reduce noise and make the tests easier to read. The remaining
CHECK-INST / CHECK-ENCODING / CHECK-ERROR coverage is unchanged.
This is a preparatory cleanup that makes the upcoming llvm-objdump
per-region disassembly change (using ISA mapping symbols #193448) easier
to review.

This PR moves `MergeConsecutiveExtractSlice` from `MergeConsecutiveInsertExtractSlicePatterns.cpp` to `FoldTensorSubsetOps.cpp`, and removes the duplicate `MergeConsecutiveInsertSlice` pattern in favor of `InsertSliceOfInsertSliceFolder`, which already exists in `FoldTensorSubsetOps.cpp` and provides equivalent functionality with greater stability. Since the merge-related patterns have been fully migrated out, `MergeConsecutiveInsertExtractSlicePatterns.cpp` is renamed to `DropRedundantRankExpansionPatterns.cpp` to better reflect its remaining responsibilities.

[lldb] Remove trailing newlines from AppendErrorWithFormat calls (part 3) (#193527)
Follow up to #193168.
This call adds a newline if there isn't one. Changing these will
eventually let us always add a newline, which is in line with
the other methods on CommandReturnObject.
This is a small part of calls found with:
* VSCode search for
`(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\\n"` and
replace with `$1"`.
* Asserting that the last character of the format string is not a
newline.
* Manual inspection.

[LLD][MinGW] Introduce --native-def argument (#193598)
This is the MinGW counterpart of -defarm64native.
When --native-def is not specified, pass the input def file as
-defarm64native on the ARM64X target as well. This reflects the most
common intent when providing a def file for ARM64X and, since the
regular def file is already passed as an input file, it feels consistent
to allow a proper build without requiring additional arguments. This can
be overridden by passing an empty value with --native-def= if using only
the EC def file is desired.

When foldICmpDivConstant encounters a signedness mismatch between the
sdiv and the icmp (e.g. icmp ugt (sdiv X, 64), 2), it previously bailed
out. This patch allows it to proceed by checking whether the sdiv's
dividend is known non-negative (via assumes/known bits) and the divisor
is a positive constant. In that case, sdiv is equivalent to udiv, so we
set DivIsSigned=false and let the existing udiv folding handle the rest.

[AArch64] Fix `shufflevector` miscompilation on `aarch64_be` (#193076)
A function like
```llvm
define <4 x i16> @xtn_shuffle_even_v8i16(<8 x i16> %a) {
entry:
%r = shufflevector <8 x i16> %a, <8 x i16> poison, <4 x i32> <i32 0, i32 2, i32 4, i32 6>
ret <4 x i16> %r
}
```
will use the `xtn` instruction, which for each 32-bit vector element
keeps only the lower 16 bits, so effectively this is a truncation.
However, if the vector actually has 16-bit elements, then the conversion
from a shuffle to a truncation is only valid on LE, not on BE. On BE,
`uzp1` should be used instead. So this PR moves some logic to right
after a check for LE, so that BE does not miscompile.
I filed this as an issue on `rust-lang-rust` as
https://github.com/rust-lang/rust/issues/155459, and we had some
discussion at [#t-libs/stdarch > `simd_shuffle!` behaves
strangely on

[DA] Remove monotonicity-related code and tests (#193697)
The concept of monotonicity was introduced in #162280 to abstract the
assumptions used in dependence tests. However, for the ZIV / SIV / RDIV
tests, this concept is excessive and not meaningful. For the MIV tests,
I believe such a concept is necessary, but since we have decided to
disable the Banerjee MIV test for now (see #174733), monotonicity has
effectively become a maintenance burden. Let's clean it for the time
being and reintroduce it only when we truly need it.

Add C++20 diagnostic to macro-braces-recovery.cpp.
For C++17 (clang's default standard) this test passes fine. For C++20 or
above standards as default this test produces an additional diagnostic

To fix this I've added a --std=c++17 to the original run line,
introduced a second run line for C++20 and a cxx20-note expectation for
the new language spec diagnostic.

HandleInlineMemberFunction before adding deferred coverage mappings,
consistent with the top-level check.
Fixes #164448.

Sub-only (partial) reductions are transformed by the LoopVectorizer to
add-reductions with a scalar sub in the middle block. When there is a
sub-reduction in a chain that has both adds and subs, the resulting
partial reduction with the negation/sub is expanded. This PR improves
codegen of such operations to make use of the [USF]MLSLB/T instructions.

[LV] Factor out VF-independent code from cost model (NFC). (#192426)
LoopVectorizationCostModel currently contains state and helpers to deal
with both VF-dependent and independent aspects of cost modeling.
Some of the state it tracks is per-VF, other state is shared across all
VFs.
This patch tries to factor out most of the VF-independent state +
functions to a new class, to try to more clearly separate those aspects,
and make it easier to reason about what decisions are independent of
VF-specific costs.

[NFC][LLVM] Simplify IIT encoding for scalable vectors (#191737)
Currently, scalable vectors are represented as an `IIT_SCALABLE_VEC`
token in the IIT info table, followed by a IIT encoding for the vector.
This requires remembering the last token seen when decoding the IIT
table and passing that into the recursive call to decode the vector.
Instead, change the representation to use:
```
IIT_V<Size>, IIT_SCALABLE_VEC (optional), Element Type
```
This allows decoding the scalable vector type without having to pass the
last token seen in `DecodeIITType` calls.

[mlir][IntegerRangeAnalysis] Don't unsoundly update constant lattice (#193546)
Fixes #119045
Integer range analysis tried to be clever and update the constant value
lattice when it inferred something to be a constant. However, this
caused correctness issues, because the integer range analysis can go
from "constant" to "not a constant" once more control edges are
analyzed, but the constant value lattice is used by dead code
elimination to skip branches ... including those that might prove that
the conditional for the branch isn't actually a constant.
Unlike in my ancient attempt at a fix, the solution is just to stop
trying to be clever.
This change required loading the constant propagation analysis in
-arith-unsigned-when-equivalent to keep tests working (which should have
been loaded anyway to make the dead code analysis work correctly).

[LangRef] Make volatile loads non-willreturn (#192992)
We currently define that volatile stores are not willreturn (i.e. they
may trap). However, volatile loads are willreturn.
I think that we should align these semantics to say that volatile
operations are always non-willreturn. There's two motivations for this:
* N3128 (part of C23) clarifies the intended meaning of "undefined
behavior" to not allow backwards propagation of UB across certain
observable side-effects, including all volatile operations. This only
made it into the standard as a non-normative note, so complying with
this is not *strictly* necessary for conformance. However, I don't think
there is a strong reason not to follow the recommendation.
* This gives a well-defined (if not very ergonomic) way to interact with
potentially trapping memory.

[AMDGPU] misched: avoid subregister dependencies (#140255)
There are some VOP3P instructions which operate on packed values
and can be configured (op_sel/op_sel_hi) to only use one of the values.
This patch adapts the scheduling dependencies so that a write to vgpr3,
for example, is not a data dependency for a read from vgpr2_vgpr3 in
case only vgpr2 is actually used.

[Lit][NFC] Refactor shell environment functionality and in-process builtins from TestRunner.py into new modules (Reopened) (#177358)
This is a fresh PR for https://github.com/llvm/llvm-project/pull/176761,
reopening after my rebasing error.
Original description:
This is the first in a series of PRs reworking Lit's handling of
in-process builtins to be run as part of command pipelines, and to
enable users to provide new in-process builtins via Lit's configuration.
The full series of patches can be found here:
https://github.com/BStott6/llvm-project/tree/lit-inproc-builtins.
This work is required for the test daemonization project:
https://discourse.llvm.org/t//88612/9
This PR moves the shell environment functionality and existing
in-process builtins from TestRunner.py into new modules. This is
important not just for organizational purposes but also because,
eventually, user defined in-process builtins will need to be able to
import items from these modules, but these cannot import TestRunner as
this would result in a dependency cycle.

[flang] Ignore -fno-realloc-lhs for polymorphic allocatable LHS with warning (#192697)
When -fno-realloc-lhs is specified and the LHS of an assignment is a
polymorphic allocatable (class(*) or class(T)), reallocation semantics
are required by the Fortran 2003 standard for dynamic type tracking and
cannot be safely skipped. Previously, the compiler generated invalid FIR
in such cases (type mismatch between i32 and
!fir.class<!fir.heap<none>>), causing a compilation error.
With this change, when -fno-realloc-lhs is in effect and a polymorphic
allocatable LHS is detected, the compiler emits a warning that the
option is being ignored for that assignment and proceeds with
reallocation semantics.

Log Message:
-----------
[AMDGPU] Fix s_cselect scc clobber issue (#193498)
The frame index elimination e.g., for S_CSELECT_B32 (which reads SCC)
uses the SCC-preserving S_ADDC_U32+S_BITCMP1_B32+S_BITSET0_B32 sequence
instead of a plain S_ADD_I32, even when the regscavenger reports SCC as
unused due to its backward scan removing the SCC def from the live set.
Root cause: scavengeRegisterBackwards scans backward from MI and calls
LiveRegUnits::stepBackward() on each instruction. stepBackward removes
defs from the live set. When it processes the S_AND_B64 (which defines
SCC) immediately before S_CSELECT_B32, SCC is removed from LiveUnits.
This makes RS->isRegUsed(SCC) return false, so NeedSaveSCC was false
before the fix.
The fix adds MI->readsRegister(SCC) to the NeedSaveSCC condition so the
SCC-preserving ADDC+BITCMP1+BITSET0 sequence is always used when MI
reads SCC, regardless of what the regscavenger reports.

should keep the function call so the programmer can observe the side

Before
https://github.com/llvm/llvm-project/commit/b9c0e590f1fd4ea37da5c2b9b78d8e715c885f56
switched the C++ status page to a reverse chronological order, it made
sense to avoid wasting vertical space for already-implemented standards.
After that switch, it would make sense however to unfold them by
default.
This is for example why I had opened #61426, because CRTL+F did not show
P0588 on the status page[^1]. But not just for this paper, I think the
ease of finding papers is a good argument for folding out those tables.
[^1]: together with the fact that other status pages
([example](https://en.cppreference.com/cpp/compiler_support/20)) have
sorted this paper under C++20 rather than C++11.

[mlir][vector] Generalize castAwayContractionLeadingOneDim (#187312)
This PR generalizes castAwayContractionLeadingOneDim to allow
accumulators with rank 1 to be matched.
With this generalization we allow the following contractions:
```
%c = vector.contract {
indexing_maps = [
affine_map<(d0, d1) -> (d0)>,
affine_map<(d0, d1) -> (d1, d0)>,
affine_map<(d0, d1) -> (d1)>],
iterator_types = ["reduction", "parallel"],
kind = #vector.kind<add>
} %0, %1, %2 : vector<64xf32>, vector<1x64xf32> into vector<1xf32>
```
to be matched and transformed to
```
map = affine_map<(d0) -> (d0)>
map1 = affine_map<(d0) -> ()>
%2 = vector.contract {
indexing_maps = [#map, #map, #map1],
iterator_types = ["reduction"],
kind = #vector.kind<add>
} %arg0, %0, %1 : vector<64xf32>, vector<64xf32> into f32
```
I noticed the following chain of transformations in IREE which led me to
this fix:
```
%23 = vector.shape_cast %22 : vector<64xf32> to vector<1x64xf32>
%24 = vector.contract {indexing_maps = [affine_map<(d0, d1) -> (d0)>, affine_map<(d0, d1) -> (d1, d0)>, affine_map<(d0, d1) -> (d1)>], iterator_types = ["reduction", "parallel"], kind = #vector.kind<add>} %14, %23, %cst_0 : vector<64xf32>, vector<1x64xf32> into vector<1xf32>
```
ContractionOpToOuterProductOpLowering
```
%23 = vector.shape_cast %22 : vector<64xf32> to vector<1x64xf32>
// transpose rhs
%24 = vector.transpose %23, [1, 0] : vector<1x64xf32> to vector<64x1xf32>
```
FoldTransposeShapeCast
```
%21 = vector.shape_cast %20 : vector<64xf32> to vector<64x1xf32>
```
With this generalization, `castAwayContractionLeadingOneDim`'s will be
transformed to a reduction during ContractionOpLowering.

IntptrTy (i32) for allocas and byval arguments, causing an assertion:
Calling a function with a bad signature!
Add CreateZExtOrTrunc to widen Size to U64Ty before the call. This is a
no-op on 64-bit targets where IntptrTy is already i64.

[DAGCombiner] Fold bswap of single-byte-known-nonzero value to a shift (#193473)
When computeKnownBits proves that a bswap operand has at most one byte
of possibly-nonzero bits at a known byte-aligned position, the bswap is
equivalent to a shift that moves that byte to the mirror position. This
is a producer-side known-bits rule; it fires in visitBSWAP regardless
of how the narrow-value provenance was established, covering shapes
such as
bswap(and X, 0xFF)
bswap(and X, 0xFF00) ; all byte positions
bswap(zext i8 X to iN)
bswap(zext i16 X to i64)
Motivation. While investigating a RISCV codegen regression under
-combiner-topological-sorting (bswap-shift.ll), I traced the root cause
to the existing consumer-side rule in
TargetLowering::SimplifyDemandedBits
for ISD::BSWAP: when a consumer demands only one byte of the bswap
result, that rule rewrites the inner bswap as a shift. Under topological
(producer-first) worklist ordering, this rewrite fires on the inner
bswap of bswap(srl(bswap X, 8)) before visitBSWAP's syntactic pattern
bswap(srl X, 8) -> (bswap X) shl 8 can collapse the whole chain, so
the outer bswap is stranded as bswap(and(X, MASK)), which no existing
combine recognizes.
The new rule is orthogonal: it matches when the operand's known bits
(rather than the consumer's demand) characterize a single-byte value,
so it closes the gap in both topological and non-topological modes. It
also captures genuinely new missed optimizations that are independent
of the ordering problem: bswap(zext i8 -> i64) previously emitted
zext.b + rev8 on RISCV+zbb and is now a single slli 56.
Placement choice. The rule is a natural dual of the existing consumer-
side rule in TargetLowering::SimplifyDemandedBits for ISD::BSWAP; the
needed information (computeKnownBits of the source) is readily
available there. I prototyped that placement and found it strictly
weaker: SimplifyDemandedBits runs later in the pipeline, typically
after integer type promotion, so a rewrite of a native i16 bswap fires
only after the value has been widened to i64 and the outer i16->i64
promotion shifts block further simplification. Placing the rule in
visitBSWAP fires pre-type-legalize on native i16/i32 values, letting
the resulting shift compose cleanly with downstream combines. A
comment in visitBSWAP cross-references the dual rule for future
readers.
Potential extension. The same logic can also be added to
TargetLowering::SimplifyDemandedBits (as a second check after the
existing one-byte-demanded rule, using computeKnownBits(Src) rather
than the demand-restricted Known2) for cases where visitBSWAP is not
reached via the combiner worklist but the bswap is recursed into by a
parent's demand analysis. I did not include that duplicate here
because no pre-existing test exercises such a path; the visitBSWAP
placement alone closes every case I found.

[libc] Honor per-test timeout in lit test format (#193772)
The custom LibcTest format did not pass litConfig.maxIndividualTestTime

hanging tests like fdiv_test on AMDGPU blocked the entire suite until
the buildbot watchdog killed the process after 1200s.
Added timeout propagation and handling of ExecuteCommandTimeoutException
to return lit.Test.TIMEOUT. This follows the same pattern used by the
GoogleTest format in googletest.py.

[RISCV][GlobalISel] Add intial support for inline asm (#193314)
This patch adds the (almost) minimal changes to support inline assembly
in the RISC-V GlobalISel backend.
The tests are mostly from
`llvm/test/CodeGen/AArch64/GlobalISel/irtranslator-inline-asm.ll` but
sadly not all test could be taken. I am planning to address the
remaining tests in later PRs.
The motivation for the PR was a fallback to SelectionDAG when compiling
libc. The motivating case can be seen in the test
`test_input_register_pointer`. That is also the reason for the small
changes in `RISCVInstructionSelector::selectCopy`.

This is the first in a series of PRs reworking Lit's handling of

This PR moves the shell environment functionality and existing
in-process builtins from TestRunner.py into new modules. This is
important not just for organizational purposes but also because,
eventually, user defined in-process builtins will need to be able to
import items from these modules, but these cannot import TestRunner as
this would result in a dependency cycle.

[flang] Support polymorphic types in conditional expressions (#192684)
Add lowering support for polymorphic (`CLASS(T)`) conditional
expressions.
`ConditionalExpr::GetType()` now checks both branches and returns the
polymorphic type if either is polymorphic (F2023 10.1.4(7)). In
lowering, polymorphic conditionals use `fir::ClassType` instead of
`fir::BoxType` for the allocatable temporary so that dynamic type info
is preserved through `hlfir.assign` realloc.
Covers scalar, array, and mixed `TYPE(T)`/`CLASS(T)` operands. Unlimited
polymorphic `CLASS(*)` does not have a declared type, and is therefore
rejected in semantics. LIT tests for lowering and semantics have been
updated.

[ConstantRange] Expand makeAllowedICmpRegion to use samesign to give tighter range (#174355)
After the addition of samesign then instcombine correctly transforms
unsigned greater than to use it if it can prove that value is greater
than zero and then removes the assume that allowed it to prove that. For
example:
```
define i8 @remove_for_samesign(i8 %x) {
%gt = icmp sgt i8 %x, 10
call void @llvm.assume(i1 %gt)
%gt.zero = icmp sge i8 %x, 0
call void @llvm.assume(i1 %gt.zero)
ret i8 %x
}
```
Is optimized to:
```
define i8 @remove_for_samesign(i8 %x) {
%gt= icmp samesign ugt i8 [[X:%.*]], 10
call void @llvm.assume(i1 %gt)
ret i8 %x
}
```
This leads to a wrong range being returned from computeConstantRange
because it doesn't look at samesign when constructing a range from
assumes, this patch fixes that.

[HLSL] Add codegen for accessing resource members of a struct (2nd merge attempt) (#193584)
Any expression that accesses a resource or resource array member of a global struct instance must be during codegen replaced by an access of the corresponding implicit global resource variable.
When codegen encounters a `MemberExpr` of a resource type, it traverses the AST to locate the parent struct declaration, building the expected global resource variable name along the way. If the parent declaration is a non-static global struct instance, codegen searches its `HLSLAssociatedResourceDeclAttr` attributes to locate the matching global resource variable and then generates IR code to access the resource global in place of the member access.

Reland PR #176893 which was an attempt to reland PR #176429.
Fix:
There was a test case asserting that for types `StructA` `StructB` where
`operator==(const StructB &, const StructA &)` is defined,
`has_equality_comparison_v<StructA, StructB>` is false because the
arguments are the wrong way around. However, in C++20, operator overload
resolution was changed so that for reflexive comparison operators `==`
and `!=` if a candidate exists with the arguments swapped then this will
be used. This means the test case failed when compiled with C++20. That
check was simply removed in this version.

[flang] Route elemental CHARACTER MIN/MAX OPTIONAL cases through custom lowering (#191244)
Follow-up to #189464.
Elemental CHARACTER MIN/MAX with dynamically optional arguments was
bypassing the custom optional-handling path and could lower incorrectly.
This change routes those cases through `genCustomIntrinsicRefCore` so
they hit the existing TODO instead of producing bad code. It also
unwraps sequence types before checking `fir::isa_char`, so the same TODO
is triggered for elemental calls as well as scalar ones, and adds a
negative test for the diagnostic.

Remove unused parameter; NFC (#193767)
As part of removing delayed typo handling in
9eef4d1c5fa6b1bcbbe675c14ca8301d5d346f7b, the KeywordReplacement
parameter ended up being unused, so this patch removes it and adjusts
the callers. This issue was discovered by a downstream static analysis
scan.
It is an NFC change because the callers of the function were looking for
a sentinel return value to determine whether they needed to call
UnconsumeToken on that parameter, but those calls cannot be reached
because the sentinel return value cannot be produced any longer.

[lit] Fix `progress-bar.py` flaky test (#193741)
The `lit` progress-bar test was checking for exact progress-bar text
like `0.. 10.. 20.. 30.. 40..`, but that output is not stable from run
to run.
The progress bar is based on timing estimates, including saved timings
from earlier runs, so small timing differences can change which numbers
get printed.
That made the test flaky: `FileCheck` could match the wrong `Testing:`
line
and then fail later, even though the actual test failures were correct.
Relax the test to verify ordering instead of exact progress-bar
contents. The updated checks assert that the test header is printed,
that
each failing test result is separated by a `Testing:` progress-bar line,
and that the final failed-tests summary lists all expected tests in
order.
This preserves coverage for the simple progress-bar path while removing
dependence on unstable timing-derived percentages.

This expands the set of scalable typed binary intrinsics which can be

provided by clang. Support for the binary ones will follow in a separate
patch.
Note that the lowering quality is terrible, particularly when the libc
entry for the scalar routine doesn't preserve vector registers (e.g.
RISC-V default). This is a functional fix to avoid crashes when trying
to codegen these, nothing more.

Host-side packing now unpacks each memref descriptor into its scalar

Add `OMPD_parallel_loop` to `GetLoopDirectives()` in the Flang OpenMP
parser so that the valid OpenMP 5.0 combined construct
`!$omp parallel loop` is recognized as a loop construct.
Previously, the parser failed to match `parallel loop` as a loop
directive. It then fell through to matching `parallel` as a block
construct, leaving `loop` as an unexpected token, producing:
```
error: expected OpenMP construct
!$omp parallel loop
^
```
The directive was already fully defined in OMP.td and handled in the
semantics directive sets, lowering, and MLIR `GenericLoopConversion`
passes. Only the parser set was missing the entry.

Re-apply "[AMDGPU][Scheduler] Use MIR-level rematerializer in rematerialization stage (#189491)" (#192443)
This fixes compilation errors in EXPENSIVE_CHECKS introduced by
[be62f27](https://github.com/llvm/llvm-project/commit/be62f270fd01e8c526f1e37df74ff1061e360dab).
This is solved by moving the EXPENSIVE_CHECKS block at its original
caller's site so that the data it reads is available.
Original PR description below.
---
This makes the scheduler's rematerialization stage use the
target-independent rematerializer. Previosuly duplicate logic is
deleted, and restrictions are put in place in the stage so that the same
cosntraints as before apply on rematerializable registers (as the
rematerializer is able to expose many more rematerialization
opportunities than what the stage can track at the moment). Consequently
it is not expected that this change improves performance overall, but it
is a first step toward being able to use the rematerializer's more
advanced capabilities during scheduling.
This is *not* a NFC for 2 reasons.
- Score equalities between two rematerialization candidates with
otherwise equivalent score are decided by their corresponding register's
index handle in the rematerializer (previously the pointer to their
state object's value). This is determined by the rematerializer's
register collection order, which is different from the stage's old
register collection order. This is the cause of all test changes but
one, and should not be detrimental to performance in real cases.
- To support rollback, the stage now uses the rematerializer's rollback
listener instead of its previous ad-hoc method (setting the opcode of
rematerialized MIs to a DBG_VALUE, and their registers to the sentinel).
This is the source of test changes in
`machine-scheduler-sink-trivial-remats-debug.mir`. The new rollback
mechanism completely removes the behavior tested by
`misched-remat-revert.ll` so the test is deleted.

With some recent refactorings, these builds are almost entirely

to get the total wall-time down.
This wouldn't have as big of an advantage if we were using the just
built base image, but should still be wall-time advantagous even if we
go back to doing that when relevant.

[CIR] Handle negative offsets in pointer constants (#193624)
When a negative offset was used as an index into a global array as part
of a global pointer initialization, CIR was hitting an unreachable
marker while trying to construct a GlobalView attribute to describe the
pointer initialization. Although this sort of negative offset is UB,
Clang allows it, so we want to produce the same results via CIR.

[CIR] Implement handling for destroying delete (#193607)
This adds CIR handling for destroying delete calls. The basic support
for deleting objects via virtual and non-virtual delete calls was
already in place. All that was needed was to add the function to emit
these calls when a destroying operator delete was encountered in
`emitCXXDeleteExpr` and to add the code to add the destroying delete tag
parameter when it is needed.
Note, classic codegen elides the destroying delete tag parameter for the
new test case because it represents an empty class. That will be handled
as part of ABI lowering in CIR, but it is not yet implemented.

[CIR] Allow multi-block ctor regions on GlobalOp (#193596)
C++14 variable templates with non-constexpr constructors (e.g., `static
const Foo<N> x{}` where `Foo()` is not constexpr) crash CIR codegen
with:
```
'cir.global' op region #0 ('ctorRegion') failed to verify
constraint: region with at most 1 blocks
```
The problem is that `GlobalOp`'s `ctorRegion` is declared as
`MaxSizedRegion<1>`, but when exceptions are enabled, `emitAggExpr` can
create additional blocks in the ctor region for EH cleanup scaffolding
(unreachable/trap terminators). These extra blocks are dead code —
`LoweringPrepare` already discards them when it moves the ctor region
into `__cxx_global_var_init`.
This patch relaxes the constraint to `AnyRegion` and replaces the
`llvm_unreachable("Multiple blocks NYI")` in the static-local guard path
with an assert (that path will be reworked by #193576).

[CIR] Add restrict→noalias on non-builtin pointer params (#191483)
Map `restrict`-qualified pointer parameters to `noalias`, skipping
builtins (e.g. `printf`) where OGCG doesn't apply it. OGCG only adds
`noalias` from `restrict` through its calling-convention lowering path,
which builtins bypass, so the `!fd->getBuiltinID()` guard keeps CIR in
line.
`constructFunctionArgumentAttributes` now takes `targetDecl` so it can
look up `ParmVarDecl` qualifiers.
Updated `asm-label-inline-builtins.c` checks to reflect the new
`noalias` on the non-builtin `__vfprintf_chkieee128` call. New test:
`restrict-noalias.c` (CIR / LLVM / OGCG).

[lldb] Speculative fix for crash in Function::GetCallEdges() (#193636)
Replace the unprotected union+bool lazy resolution in DirectCallEdge
with `std::call_once`/`std::once_flag`.
Multiple threads can call `GetCallee` on the same edge concurrently and
the old code had no synchronization on the union discriminator or its
contents. This could lead to a corrupted pointer that would explain the
crash we're observing sporadically.

Remove the getLinkerVersion checks that gated default enablement of

AArch64 Darwin targets.
The linker support for these stubs was added a long time ago, so the
version checks are no longer necessary. Additionally, getLinkerVersion
returns the version of the linker that was used to build clang, which
can differ from the linker actually used at invocation time, making the
check unreliable.

[MLIR][Mem2Reg] Ensure dominance of default value in regions (#193708)
When we promote an allocation, and a default value for a load from an
uninitialized slot is required, this value used to get inserted in the
same block as the allocation. However, in some cases, the default value
needs to be available in the predecessor blocks so that they can pass it
to the block of the allocation as an argument. For example, this is the
case for loops containing an allocation where the promoted value will
become and IV.
Make sure the default value is always available to all blocks by
creating it in the entry block of the region.
For reference, this is what used to be the output for the test. Note the
use of `%1`.

[PreISelIntrinsicLowering] Use index type for index in intrinsic expansion (#193807)
We'd chosen intptr type for the binary in review, but on reflection the
index type is probably a conceptually better fit. On riscv, these are
going to be the same, so it's purely a conceptual issue.
For the unary case, this is an actual change since we were using i64
unconditionally. This improves codegen for RV32 by avoiding the need for expensive legalization of i64 expressions for the IV.

[mlir][canonicalize] Add filter-dialects option (#193041)
Add a new `filter-dialects` list option to the canonicalize pass. When
provided, only canonicalization patterns from the listed dialects are
collected, and the named dialects are force-loaded via
getDependentDialects.
Loading flow: the Canonicalizer's getDependentDialects override calls
`registry.addDialectToPreload(name)` for each filter-dialect name, which
records the name in a new `dialectsToPreload` list on DialectRegistry.
The PassManager's pipeline-init then calls
`dependentDialects.preloadSelectDialects(ctx, emitError)`, which loads
each preload entry via `context->getOrLoadDialect(name)` — the real
allocator is resolved from the context's own registry (registered by
the tool) and the dialect is loaded before multi-threaded execution
begins. If a requested dialect has no registration in the context, a
diagnostic `"can't load dialect '<name>': missing registration?"` is
emitted.
DialectRegistry API changes:
- New `addDialectToPreload(StringRef)` method: records a dialect name
that should be loaded into the MLIRContext but whose allocator lives
in the context's own registry. The registry itself does not load the
dialect — it just carries the request.
- New `preloadSelectDialects(MLIRContext *,
function_ref<InFlightDiagnostic()> = {})`
method: loads every preload-registered dialect into the context,
returning failure (and optionally emitting a diagnostic) for the
first name that cannot be resolved.
- `getDialectNames()` is split into two accessors:
* `getRegisteredDialectNames()` — names of allocator-backed entries
from the registry map.
* `getDialectsToPreload()` — preload-only entries added via
`addDialectToPreload(StringRef)`.

call sub((x > 10 ? a : x > 5 ? b : c))
call sub((flag ? a : .NIL.))
- Add ConditionalArg and ConditionalArgTail parse tree nodes
- Add Nil empty class for .NIL. representation
- Add ConditionalArg as a new alternative in ActualArg
- Add parser rules for conditional-arg, consequent, and chained branches
- Add unparse support for round-trip printing
- Add dump-parse-tree and FeatureList support
- Add parser tests covering simple, multi-branch, .NIL., BOZ, NULL(),
keyword arguments, and module procedure cases

[Clang] Fix sret AS for non-trivial-copy returns. (#186275)
classifyReturnType used getAllocaAddrSpace() for sret, which is wrong
on targets like AMDGPU where alloca lives in addrspace(5). For types
with deleted copy/move constructors, there is no way to construct into
a temp and copy out — the sret pointer must point directly to the caller's
destination in the default address space.
Add a target hook getSRetAddrSpace() so AMDGPU can return LangAS::Default
for non-register-passable types.

ReturnsNonNullAttr (e.g. operator new), guarded by !NullPointerIsValid.
Add nonnull to pointer parameters with __attribute__((nonnull)), both
per-parameter and function-level forms.
Thread targetDecl into constructFunctionArgumentAttributes and build a
parallel ParmVarDecl array in the zip_equal loop to access
parameter-level attributes without manual index arithmetic.
Restrict->noalias handling has been moved to #191483.

[lldb/test] Fix TestOSIndSYM for Darwin embedded platforms (#193839)
The test used CreateTarget(None) and relied on the attach to discover
the executable and load the dSYM. On remote platforms this doesn't find
the local dSYM, so the OS plugin never loads. Switch to
CreateTarget(executable) so the dSYM Python module is loaded before
attach.
Also split the test into two methods: test_python_os_plugin uses
spawn+attach which works both locally and on real remote platforms,
while test_python_os_plugin_remote simulates remote debugging by
manually spawning debugserver and is skipped on embedded platforms where
this setup conflicts with lldb-platform.

[flang][cuda] Preserve fir.rebox captured by cuf.kernel in SimplifyArrayCoorOp (#193837)
SimplifyArrayCoorOp folds fir.rebox → fir.array_coor by rewriting the
array_coor to consume the rebox's source box directly. This is unsafe
when the array_coor is inside a cuf.kernel and the rebox is not: in CUF,
a rebox of a device-attributed value (e.g. a dummy with cuf.data_attr =
device) is the op whose lowering copies the descriptor into
GPU-accessible memory. Folding it out skips the copy, so the kernel
dereferences a host-side descriptor on the device, causing
cudaErrorIllegalAddress (or cudaErrorUnknown on H100 under ATS).
The pattern already guards this hazard for OpenACC via
ACC_COMPUTE_AND_DATA_CONSTRUCT_OPS / ACC_DATA_ENTRY_OPS; this change
adds the analogous guard for cuf::KernelOp.

[MachineOutliner] Do not allow debug instructions to affect liveness computations. (#192336)
Because DBG_VALUE precedes the actual definition of a physical register,
considering
these during the liveness updating phase of MachineOutliner was causing
every register
definition to also be marked as a use, which would eventually lead to a
verifier error
when a use without a def was detected.
A MIR testcase for this is present at
https://github.com/CHERIoT-Platform/llvm-project/commit/b71f6d67e338e70a1dc23e15a77805da3e3cd015
but it depends on CHERIoT instructions that are not in LLVM upstream at
present. It's also very senstive to small changes to the input, so I
have not been able to reproduce it on an in-tree target. That said, I
believe this change is small enough that its correctness is verifiable
by inspection.

[CIR] Handle boolean expression as array indexes (#193814)
We were hitting a CIR verification error in some cases when a boolean
expression was used as an index to an array because the GetElementOp
verifier expected the index operand to be a fundamental integer type. To
fix this, I'm updating the emitArraySubscriptExpr to cast index values
to ptrDiffTy, which more closely matches what classic codegen does in
the corrsponding code.
The improved alignment with the classic codegen implementation caused
some minor changes in generated IR that required some tests to be
updated.

Reapply "[clang][modules-driver] Add support for C++ named modules and `import std`" (#193815)
This reverts #193677 and relands #193312.
This adds basic support for explicit C++ named module builds, managed
natively by the Clang driver, including support for use of the Standard
library modules. This follows #187606, which adds the same for Clang
modules.
Current limitations:
- Standard library modules are still compiled to object files instead of
using the provided shared library. (This will be addressed in a
follow-up soon.)
- Caching is not supported yet (but likely to be added during the
upcoming GSoC cycle).
- Importing C++ standard library modules into Clang modules is not
supported (and not expected in the near term).

[CIR] Add coroutine cleanup handling and update co_return semantics (#189281)
This PR adds cleanup handling for coroutine frame destruction. The
cleanup is emitted as a conditional that checks the result of the
`coro.free` builtin, which is used to determine whether the coroutine
frame was heap-allocated, if the returned pointer is null, no
destruction is performed. Additionally, this PR changes how co_return is
represented: previously, it was lowered directly into a branch to the
block containing the final suspend logic, but now a new `cir.coro.body`
operation is introduced to represent the user-written coroutine body.
Inside this region, `cir.co_return` operations mark exits from the
coroutine body and represent structured control flow that transfers
execution to the final suspend point. The lowering of this structured
control flow into explicit branches is deferred to a future PR in the
FlattenCFG pass.

[Clang][CodeGen] Fix sret lifetime marker AS mismatch after #186275 (#193850)
After #186275, the sret address space can differ from the alloca address
space (e.g., AS 0 vs AS 5 on AMDGPU). In CGCall.cpp EmitCall(), when a
discarded-value sret temporary is created, SRetPtr is allocated in the
alloca AS and a lifetime.start is emitted. The pointer is then
addrspacecast'd to match the sret AS, but the CallLifetimeEnd cleanup
was using the addrspacecast'd pointer, triggering an assertion in
EmitLifetimeEnd ("Pointer should be in alloca address space").
Saves the original alloca pointer before the addrspacecast and uses it
for the lifetime-end cleanup.

could be combined into them. Now that these intrinsics are expanded too,
the lowering for these is dead and can be removed.

[clangd] [C++20] [Modules] Introduce persistent cache for clangd built module file (#193883)
Currently clangd lacks a persistent cache for clangd built module file.
It implies that every time a new clangd process starts, or a user close
all tabs and opening all a new tab. Clangd will build all the module
files required. This is a slow process. Especially, the building happens
in the building thread for the opening tab. That is, if the user only
opens a single tab, clangd needs to build all the module file in a
single thread. This is very slow in practice.
As clangd is basically a wrapper for clang, we can't do nothing to speed
the building process actually and the only thing we can do is to
introduce a better cache mechanism.
So everytime the user opens a new tab, now clangd won't try to build all
the needed module file at first but try to see if these module files are
already built and up-to-date. So clangd can try to avoid a lot of time
to rebuilding the same thing.
For details,
now the built module file will live in
<cache-root>/<module-unit-source-name>-<source-hash>/<command-hash>/<module-name>[-<version>].pcm
Here <cache-root> stands for
<path-to-compilation-database>/.cache/clangd/modules or
<user-home>/.cache/clangd/modules
the <source-hash> in <module-unit-source-name>-<source-hash> means the
hash of the path of the corresponding module unit, as we can have
different a.cppm in different directories in a project.
<command-hash> means the hash of the command. As we can produce
different BMI with different command.
Then <module-name>.pcm means the newest BMI. And
<module-name>-<version>.pcm means a CopyOnRead BMI of <module-name>.pcm.
We did this to ease the concurrency management. As now, we can be sure
<module-name>.pcm won't be used by anyone in clangd itself.
TODO: We didn't implement a GC so that cache size may increase
consistently. We will didi that in following patches.
AI assisted.

[IR] Remove pointer arguments from loop.dependence.{war|raw}.mask (#188248)
Passing pointer arguments is quite inconvenient for practical use. These
intrinincs only care about the difference between the address bits of
two pointers, but by taking pointer arguments it is implying they care
about other details of the pointers (such as addrspace, or other pointer
bits).
This metadata is currently not preserved when gathering diff checks in
the loop vectorizer, so requiring pointers makes emitting these
intrinsic more complex (or requires preserving information that is
ultimately unused).

[lldb] Add regression test for stale Symbol pointer crash in statusline (#193854)
Add a test that exercises the code path fixed in
[88f024223cc4](https://github.com/llvm/llvm-project/pull/188377)
("[lldb] Fix stale Symbol pointer crash in statusline after 'target
symbols add'").
The bug: when `target symbols add` is called, `Symtab::AddSymbol()` can
reallocate the underlying `std::vector<Symbol>`, invalidating all
existing `Symbol*` pointers. The statusline caches an
`ExecutionContextRef` containing a `StackID` with a
`SymbolContextScope*` (which can be a `Symbol*`). If a concurrent
statusline redraw occurs between the Symtab reallocation and
`Process::Flush()` (e.g. from a progress event on the event handler
thread), the cached `StackID` matches the old frame via pointer-equal
comparison, and `GetSymbolContext()` dereferences the dangling
`Symbol*`.
The test:
1. Builds a stripped binary and its unstripped counterpart.
2. Runs the stripped binary and stops at a breakpoint in `main`.
3. Enables the statusline (populating the cached `ExecutionContextRef`).
4. Calls `target symbols add` to add debug symbols back.
5. Forces a statusline redraw via terminal resize, which calls
`Redraw(std::nullopt)` using the cached (potentially stale) execution
context.
6. Verifies the statusline still renders correctly.
The dangling pointer is a use-after-free that silently succeeds in
non-sanitizer builds (the freed memory is still accessible). This test
is most effective under AddressSanitizer, which poisons freed memory and
immediately detects the stale access.

[mlir][EmitC] Add tests for arith.max/min float/signed int conversions (#190160)
This patch adds test coverage for the combined `-arith-expand |
-convert-arith-to-emitc` pipeline for selected `arith` max/min operations.
The new tests exercise:
- `arith.maximumf`
- `arith.minimumf`
- `arith.minsi`
- `arith.maxsi`
The intent is not to re-test the individual passes in isolation. Expansion is
already covered in `test/Dialect/Arith/expand-ops.mlir`, and the direct
Arith-to-EmitC lowering is already covered in
`test/Conversion/ArithToEmitC/arith-to-emitc.mlir`. This patch specifically
checks that the combined pipeline produces the expected EmitC operations after
expansion.
For floating-point max/min, the test verifies the expanded form lowers to the
expected sequence of `emitc.cmp`, `emitc.logical_or`, and `emitc.conditional`
operations. For signed integer min/max, it verifies lowering to the expected
`emitc.cmp` and `emitc.conditional` sequence.
The test also documents currently unsupported cases for the combined pipeline:
vector cases are excluded because expansion introduces `arith.cmpf`, and
`ArithToEmitC` does not convert `VectorType`; tensor cases are excluded because
`ArithToEmitC` only lowers scalar `cmpf`.
Assisted-by: Codex (refine tests and comments).
I reviewed all code and tests before submission.

[LV] Simplify live-out extraction for first-order recurrence phis when tail folding (#176108)
The idea is similar to ba40a7bc2e65be86ac23c9cf6038ac085dda77eb. Due to
tail folding, the recurrence vector in the final iteration may contain
only a single active element, making it impossible to extract the
penultimate active element. This patch instead directly extracts the
last active element from the vector produced by splicing the recurrence
phi and the previous value, without needing to select which value to
extract based on the number of active lanes.

[libc] Honour LIBC_GPU_TEST_JOBS in lit test runs (#193797)
Under CTest, LIBC_GPU_TEST_JOBS controlled a ninja job pool that limited
concurrent GPU test processes. The AMD GPU buildbot sets this to 4 to
avoid overloading the GPU driver.
When running tests via lit, this constraint was lost because lit uses
its own -j flag (defaulting to nproc, or set to 64 on the AMD bot via
LLVM_LIT_ARGS). All GPU loader processes launched simultaneously,
leading to hangs from GPU resource exhaustion.
Propagated LIBC_GPU_TEST_JOBS into the lit site config as a parallelism
group so lit throttles GPU test concurrency independently of the global

[libc] Switch check-libc from CTest to lit (#193798)
Renamed check-libc-lit to check-libc, replacing the old CTest-driven
target. Dependencies now use -build targets (e.g.
libc-hermetic-tests-build) so that check-libc only builds test
executables and delegates execution to lit.

[flang][debug] generate llvm.fake.use for arguments at -g and O0 (#187044)
Fix for https://github.com/llvm/llvm-project/issues/185432.
This patch extends the lifetime of procedure dummy arguments using llvm.fake.use
so that they are accessible in debugger during the whole lifetime of the function.
This is done by:
- adding a new fir.fake_use operation and emitting it in AddDebugInfo.cpp for
dummy arguments at the end of the procedure scope.
- lower this new fir.fake_use to the llvm.fake.use intrinsic.
This is done under -g at O0 only to avoid pessimizing the generated code when
optimizations are requested.

[lldb][test] Remove full stop from expected error messages (#193748)
I am about to update a bunch of uses of AppendErrorWithFormat to not
have a full stop at the end, to confirm to
https://llvm.org/docs/CodingStandards.html#error-and-warning-messages.
Reviewing all those changes is going to be difficult so I am updating
the tests first and then we can land the other changes in batches
(because the tests will continue to pass as we do that).
Note that I have only run the test suite on Linux AArch64, so there are
probably more that need to be updated. We will catch those in CI or
post-commit.

To fit the style guide:

I found these with:
* Find `(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\."`
and replace with `$1"` using Visual Studio Code.
* Putting a call to `validate_diagnostic` in `AppendErrorWithFormat`.
* Manual inspection.
Note that this change *does not* include a call to `validate_diagnostic`
because I do not know what's going to crash on platforms that I haven't
tested on.

[mlir][math] Use APFloat::SemanticsToEnum in constant folding (#193914)
Refactor constant folding in the Math dialect to use APFloat::SemanticsToEnum() instead of getSizeInBits() when checking
floating-point semantics. Inferring semantics from bitwidth is fragile: different formats may share the same bit width but have distinct semantics, leading to incorrect dispatch. SemanticsToEnum() matches on the exact semantics descriptor, making the intent explicit and ensuring correct dispatch.

The missing support was highlighted while building an opensource

[lldb][Linux] Read memory protection keys for memory regions (#182246)
Memory protection keys
(https://docs.kernel.org/core-api/protection-keys.html) are implemented
using two things:
* A key value attached to each page table entry.
* A set of permissions stored somewhere else (in a register on AArch64
and X86), which is indexed into by that protection key.
So far I have updated LLDB to show the permissions part on AArch64 Linux
by reading the por register. Now I am adding the ability to see which
key each memory region is using.
```
(lldb) memory region --all
[0x0000000000000000-0x000aaaae3b140000) ---
[0x000aaaae3b140000-0x000aaaae3b150000) r-x /tmp/test_lldb/linux/aarch64/permission_overlay/2/TestAArch64LinuxPOE/a.out PT_LOAD[0]
protection key: 0
[0x000aaaae3b150000-0x000aaaae3b160000) rw- /tmp/test_lldb/linux/aarch64/permission_overlay/2/TestAArch64LinuxPOE/a.out
protection key: 0
```
The key is parsed from the /proc/.../smaps file, and so will only be
present for live processes, not core files.
This is sent as part of the qMemoryRegionInfo response as a new
"protection-key" key. As far as I know "memory protection keys" are
Linux specific, but I don't know of a good generic name for it, so I've
copied what smaps calls it.
I have updated the "memory region" command to show this key. A lot of
the time this will be the default 0 key. I considered hiding this, but
decided that for this initial support it's better to be explicit and
verbose (this also prevents a Linux specific detail being added to the top level
memory region command).
I have not added protection keys to the SBAPI because:
* I don't know of a specific need for them.
* They are very easy to add if someone does want them later (just a
HasProtectionKey and GetProtectionKey).
* Arm's POE2
(https://developer.arm.com/community/arm-community-blogs/b/architectures-and-processors-blog/posts/future-architecture-technologies-poe2-and-vmte)
is coming soon, which makes these permissions more complex. There's no
need to risk adding something too simple to handle those.
The ability to see the permissions the key refers to, and the final
permissions after the overlay, will be in a follow up PR.

-----------
[LangRef] Allow monotonic & seq_cst accesses to inter-operate with other accesses (#189014)
Currently, the LangRef says that atomic operations (which includes `unordered`
operations, which don't participate in the monotonic modification order) must
read a value from the modification order of monotonic operations.
In the following example, this means that the load does not have a store it
could read from, because all stores it may see do not participate in the
monotonic modification order:
```
; thread 0:
store atomic i32 1, ptr %p unordered, align 4
; thread 1:
store atomic i32 2, ptr %p unordered, align 4
load atomic i32, ptr %p unordered, align 4
```
The same applies if the load is monotonic instead of unordered (or if it is
replaced by a monotonic RMW operation). Either case seems wrong.
Similarly, the LangRef currently says "Each sequentially-consistent read sees
the last preceding write to the same address in this global order [of seq_cst
operations]." Strictly read, this means that the load in the following example
must read from the first store (or at least cannot read the second one),
because the second one is not sequentially consistent and therefore not in the
seq_cst order. That also seems wrong.
```
; thread 0
store atomic i32 1, ptr %p seq_cst, align 4
store atomic i32 2, ptr %p monotonic, align 4
load atomic i32, ptr %p seq_cst, align 4
```
This patch aims to resolve these inconsistencies.

Reland "[lldb][Linux] Read memory protection keys for memory regions (#193934)" (#193936)
This reverts commit 390a29ea833965f481a7011b07deed9612229d6e.
Two tests failed on the X86 buildbot but not in GitHub CI because the
buildbot has protection keys and the CI machines do not. I ran the tests
on an AArch64 host without protection keys, and only selected tests on a
simulated AArch64 machine with protection keys, so I did not find this
earlier.
The fix was to add "protection-key" to the list of possible
qMemoryRegionInfo response keys.

`FEAT_MPAMv2_VID` instructions and system registers, as introduced
in change d30f18d2c, are being removed at this time, as they've been
removed from the latest Arm ARM, which doesn't preclude them returning
in some form in future.
Other system registers introduced with `FEAT_MPAMv2` are unaffected,
and these continue to be ungated, but since `+mpamv2` gating is now
empty,
I'm removing this superfluous gating code.

[flang][OpenMP] Make OpenMPLoopConstruct inherit from OmpBlockConstruct (#193823)
Conceptually OpenMPLoopConstruct has the exact same structure as
OmpBlockConstruct: directive specification for the begin directive,
optional one for the end directive, and a block of code. The reason why
OpenMPLoopConstruct was not originally made to be a descendant of
OmpBlockConstruct was to preserve the behavior of AST visitors, where a
separate (type-based) visitor could be defined for the begin/end
directives of a block construct, and for a loop construct. The AST nodes
representing the begin/end directives in block and loop construct had
different types: Omp{Begin|End}Directive for block constructs, and
Omp{Begin|End}LoopDirective for loop constructs.
Today this distinction is not needed anywhere, and so the loop construct
will be represented in the same way as a block construct.

[lldb][Linux] Add overlay and effective permissions to "memory region" (#184115)
In this change I'm extending the "memory region" command to show users
the
overlay permissions that a protection key refers to, and the result of
applying that overlay to the page table permissions.
For example, protection key 0 refers to Perm0 in the por register.
```
(lldb) register read por
Perm0 = Read, Write, Execute
```
This is the default key, so many regions use it.
```
(lldb) memory region --all
<...>
[0x000ffffff7db0000-0x000ffffff7f40000) r-x /usr/lib/aarch64-linux-gnu/libc.so.6 PT_LOAD[0]
protection key: 0 (rwx, effective: r-x)
```
Protection keys can only change what was already enabled in the
page table. So we start with read and execute. Then a read/write/execute
overlay
is applied. We cannot add write, so the result is read and execute.
Here's an example of its use with a real crash (output edited):
```
(lldb) c
* thread #1, name = 'test.o', stop reason = signal SIGSEGV: failed protection key checks (fault address=0xffffff7d60000)
-> 106 read_only_page[0] = '?';
(lldb) memory region 0xffffff7d60000
[0x000ffffff7d60000-0x000ffffff7d70000) rw-
protection key: 6 (r--, effective: r--)
(lldb) register read por
Perm6 = Read
```
The calculation of permissions is implemented by a new ABI method.
It's in ABI for 2 reasons:
* These overlays are usually in a register (X86 and AArch64 are)
and that register name is architecture specific.
* The way the overlay values apply may differ between architecture.
AArch64 treats a set bit as adding a permission, but some may
treat it as removing.
Technically this is dependent on operating system and architecture.
However, so are the methods for removing non-address bits, and those
are in ABI too.
To test this I have changed the allocations in the test program
to use read+execute permissions by default. With read+write+execute
I could not observe that the overlay only changes enabled permissions.

[mlir][tosa] Fix integer bilinear (quantized) tosa.resize lowering to use floordivsi (#193821)
## Background
`tosa.resize` in bilinear integer (quantized) mode lowers to a
`linalg.generic`
body that, for each output pixel, computes a corresponding input
coordinate and
blends the four neighboring input pixels. The mapping is:
```
val = out_coord * scale_d + offset
index = val / scale_n // integer part — which input pixel to start from
delta = val - index * scale_n // fractional part, scaled to [0, scale_n)
```
`delta` is the interpolation weight toward the next pixel. The bilinear
formula
(integer path) is:
```
topAcc = pixel[y0,x0] * (scale_x - dx) + pixel[y0,x1] * dx
bottomAcc = pixel[y1,x0] * (scale_x - dx) + pixel[y1,x1] * dx
result = topAcc * (scale_y - dy) + bottomAcc * dy
```
For this to be a valid convex combination (interpolation, not
extrapolation),
`dx` and `dy` must be in `[0, scale_n]`.
The pixel indices `y0`, `y1`, `x0`, `x1` are computed by
`getClampedIdxs`:
```cpp
y0 = clamp(iy, 0, H-1)
y1 = clamp(iy+1, 0, H-1)
```
---
## The Bug
The integer path uses `DivSIOp` (truncation toward zero):
```cpp
// getIndexAndDeltaInt — mlir/lib/Conversion/TosaToLinalg/TosaToLinalg.cpp
index = arith::DivSIOp::create(b, val, scaleN); // truncates toward zero
delta = arith::MulIOp::create(b, index, scaleN);
delta = arith::SubIOp::create(b, val, delta); // = val - (val/scaleN)*scaleN
```
When `val < 0` (which happens at boundary output pixels when `offset` is
negative), `DivSIOp` truncates toward zero instead of toward -∞. This
produces
a negative remainder, i.e. a negative `delta`, which causes
extrapolation.
Note: the code comment on line 2058 already says `// ix = floor(x /
scale_n)`,
but the code uses truncation — this mismatch is the root cause of the
bug.
The float path (`getIndexAndDeltaFp`) uses `FloorDivSIOp` and is
unaffected:
with floor division, `r = val - floor(val/scaleN)*scaleN` is always in
`[0, scaleN-1]`.
---
## Concrete Example
**Setup:** 2×2 input upsampled to 4×4, `scale=[4,2,4,2]`,
`offset=[-1,-1]`
- `scale_y_n=4`, `scale_y_d=2`, `scale_x_n=4`, `scale_x_d=2`
- `offset_y=-1`, `offset_x=-1`
- Input: `tensor<1x2x2x1xi8>` with `input[0,0,0,0]=100`, all others `0`
**At output pixel (0,0):**
```
val = 0 * 2 + (-1) = -1
```
### Without any fix (DivSIOp, buggy)
```
iy = DivSIOp(-1, 4) = 0 // truncates -0.25 toward zero
dy = -1 - 0*4 = -1 // OUT OF RANGE: should be in [0, 4]
y0 = clamp(0, 0, 1) = 0
y1 = clamp(0+1, 0, 1) = 1 // different rows
ix = DivSIOp(-1, 4) = 0
dx = -1 // same issue
x0 = clamp(0, 0, 1) = 0
x1 = clamp(0+1, 0, 1) = 1
// pixels:
y0x0 = input[0,0,0,0] = 100
y0x1 = input[0,0,1,0] = 0
y1x0 = input[0,1,0,0] = 0
y1x1 = input[0,1,1,0] = 0
topAcc = 100*(4-(-1)) + 0*(-1) = 500 // EXTRAPOLATION
bottomAcc = 0*(4-(-1)) + 0*(-1) = 0
result = 500*(4-(-1)) + 0*(-1) = 2500 // WRONG
```
### Fix w/ FloorDivSIOp
```
iy = FloorDivSIOp(-1, 4) = -1 // floors -0.25 toward -∞
dy = -1 - (-1)*4 = 3 // naturally in [0, scale_n-1]
y0 = clamp(-1, 0, 1) = 0
y1 = clamp(-1+1, 0, 1) = 0 // SAME row — both snap to boundary
dx = 3 (same by symmetry)
// all four neighbors collapse to the same boundary pixel:
y0x0 = y0x1 = y1x0 = y1x1 = input[0,0,0,0] = 100
topAcc = 100*(4-3) + 100*3 = 400
bottomAcc = 100*(4-3) + 100*3 = 400
result = 400*(4-3) + 400*3 = 1600 // correct
```
`y0=y1=0` means boundary replication is enforced by `getClampedIdxs`,
making
`dy` irrelevant.
## Semantic Analysis of the fix
- `iy=-1` correctly signals "this position is before the first input
pixel."
- `getClampedIdxs` does its intended job: both `y0` and `y1` snap to the
boundary pixel, enforcing replication explicitly.
- `dy=3` **appears** valid (it's in `[0, scale_n-1]`) but is
semantically
meaningless: the true position is `-0.25`, which is outside the image —
there
is no "3/4 toward the next pixel" to interpolate toward. It is harmless
only
because `y0=y1`.
- Same analysis for dx=3 by symmetry.
- Fixes the root cause (wrong division op, matching the existing code
comment
and mirroring the float path), but `delta` still carries a misleading
value
at out-of-bounds positions.

[CIR] Introduce LocalInitOp, & lower static locals (#193576)
During an investigation of something else, I discovered that our
handling of static-local as a ctor/dtor on a GlobalOp meant that it
couldn't actually be initialized with reference to any local, parameter,
or member declarations. This is obviously problematic.
This patch instead introduces a `LocalInitOp`, which is an operation
that represents the location of initialization for the static local.
This is lowered during lowering-prepare, same as we did previously (in
fact, it uses basically the exact same lowering code, with some slight
modifications).
Lowering from AST itself splits slightly from global declarations, but
the two share implementation as closely as possible.
At the moment, this operation only works for static-locals, and has a
handful of asserts to do the same. It is intended that the
thread-local-storage use the exact same mechanism, with some slight
modifications to the lowering-prepare pass to introduce the different
init behavior.

* Adds a new warning emitted for use-after-free.
* Renames `reportUseAfterFree` to `reportUseAfterScope`, since the old
name was misleading (the warnings are still called `use_after_scope`).
* Adds a new `AccessPath::Kind` value, `NewAllocation`, which is used

* Adds `VisitCXXNewExpr` and `VisitCXXDeleteExpr`, which handle loan
issuance and origin propagation for `new` and `delete`.
* Comes with extensive test coverage for the new features, including new
use-after-free tests and use-after-scope coverage for `new`.
Remerges #192504
# Changes over original PR
* Fixed a crash when allocating `void*`, and added a regression test for
it
* The `AccessPath` root implementation was changed in #193520, so this

[clangd] [C++20] [Modules] Introduce GC for clangd built modules (#193973)
This patch introduces simple GC for clangd built module files to avoid
the clangd built module cache to increase infinitely.
The strategy is, in a clangd built module file cache, if the clangd
built module (we think all PCM files in clangd cache are built by
clangd) was not accessed in a time (by default 3 day, controlled by
--modules-builder-versioned-gc-threshold-seconds)，clangd will remove it.
The strategy is not perfect. e.g., I heard in some systems, the atime
was forbid or not update. But given a trade off between usability and
maintainability. I feel the current stategy is fine.

[lldb][AArch64][Linux] Rename "por" register to "por_el0" (#193983)
As agreed with my Arm colleagues working on GDB.
The suffix means we are matching the architectural name exactly, and
reducing confusion if you're
debuging multiple exception levels where there could be por_el<N> as
well.
In the process of updating the tests I found some
"register read" output has changed alignment so I
have fixed that too.

This enables the instruction to be disassembled regardless of what bits
are in those fields, which helps diagnose broken code. Previously, the

of app address space; addresses differing only in bits 28-31 alias in
the shadow. kAppAddr is set to 0xC0000000 to size the mmap to exactly
the 1GB shadow region.

This reverts commit a1d11348aba4b70295ef9ada4a13a722455165d3.
Two problems have been identified:
- The expansion for powi was functionally wrong - the second argument
stales scalar even when the first is a vector.
- AArch64 uses the Expand option on libcalls to select vector libcalls
in some cases. The test coverage for this uses -start-after which
happens to miss this pass.

We observed that following command can cause an assertion fail
`flang -fopenmp -fdo-concurrent-to-openmp=devic,e` <file>
It happened because `parseDoConcurrentMapping` reported an error but
still called `val.value()` on failure, tripping std::optional
assertions.
The fix is to return false on error and wire return into
`createFromArgs`.

CodeGen: Fix double counting bundles in inst size verification (#191460)
The AMDGPU implementation handles bundles by summing the
member instructions. This was starting with the size of the
bundle instruction, then re-adding all of the same instructions.
This loop is over the iterator, not instr_iterator, so it should
not be looking through the bundled instructions. Most of the other
uses of getInstSizeInBytes are also on the iterator, not the
instr_iterator so the convention seems to be targets need to handle
BUNDLE correctly themselves.

[ThinLTO] Reduce the number of renaming due to promotions in distribu… (#188074)
…ted mode
For thin-lto, the pull request [1] reduced the number of renaming due to
promotions in process mode. This has been used in linux kernel ([2]) as
it helps kernel live patching a lot.
Recently, I found Rong Xu has added thin-lto distributed mode support in
linux kenrel ([3]) and it is likely to be merged in kernel as well. So
it would be a good idea for llvm to support reducing the number of
renaming in distributed mode too.
To implement this, in function gatherImportedSummariesForModule(),
import functions into summaries if those functions does not need rename.
This will ensure that imported functions have the same name as in there
original module.

[SLP] Skip FMulAdd conversion for alt-shuffle FAdd/FSub nodes (#193960)
isAddSubLikeOp() admits alt-shuffle nodes that mix FAdd and FSub, so
transformNodes() was marking them with CombinedOp = FMulAdd. The cost
model then priced the node as a single llvm.fmuladd vector intrinsic,
but emission for an alt shuffle still goes through the ShuffleVector
path and produces fmul + fadd + fsub + shufflevector, which the backend
cannot fuse into a single fmuladd. The resulting under-count made SLP
choose the vector form over the scalar form even when the scalar form
lowers to real FMAs (e.g. fmadd + fmsub on AArch64).

[DirectX] Denote `dx.resource.getpointer` with `IntrInaccessibleMemOnly` and `IntrReadMem` (#193593)
`IntrConvergent` was originally added to `dx.resource.getpointer` to
prevent optimization passes (`SimplifyCFG`, `GVN`) from sinking the
intrinsic out of control flow branches, which would create phi nodes on
the returned pointer.
Using `IntrInaccessibleMemOnly` and `IntrReadMem` semantics still
prevent passes from merging or sinking identical calls across branches.
However, this allows the call to be moved within a single control flow
path.
Updates relevant tests and adds a new test to demonstrate a now legal
potential optimization.
This was discovered when
https://github.com/llvm/llvm-project/pull/188792 caused the following
failure:
https://github.com/llvm/llvm-project/actions/runs/24577221310/job/71865579618.
When emitting convergence control tokens, each resource access is then a
user of the convergence control tokens, which makes it's use more
unnecessarily restrictive for optimizations and in this case would
prevent a loop unroll from taking place.

addresses matching. Since Clang allows this, this change is updating the
cir.copy operation to allow it.

[flang] [flang-rt] Implement AT edit descriptor for Fortran 202X with appropriate handling and tests (#189157)
This PR is to add AT edit descriptor, a new feature of Fortran 2023, 5.1
US 10.
AT is like A (character output) but trims trailing blanks before
emitting the string. AT is functionally the same as TRIM intrinsic.
AT is treated as a variant of A during parse. The trimming of the
trailing spaces are implemented the same as TRIM(). There exists a
method, LenTrim, that can be used to do the trimming. However it's local
to a different .cpp file, character.cpp. And the code is so simple that
no need to make extra effort to use LenTrim.
AT is output only and do not accept width.
This PR will fix #181379.

[llvm] Introduce TargetInfo (#190730)
This PR introduces ABIInfo and TargetCodeGenInfo, the abstract ABI
lowering layer for the LLVM ABI library introduced in #158329.
This is a direct parallel to clang::ABIInfo and
clang::TargetCodeGenInfo, but operating entirely on the llvm::abi type
system rather than Clang's AST, keeping ABI logic independent of the
frontend. It is a prerequisite for implementing the target specific
lowering passes that lower FunctionInfo to LLVM IR calling conventions.

[CIR] Update uses of no-prototype GetGlobalOp (#193868)
When a no-prototype function is replaced by a proper definition, we
update uses of the previous function, mostly cir::GetGlobalOp
operations. If the result of the GetGlobalOp was being used in a store,
this was leading to verifier errors because the type being stored no
longer matched the expected type. This change fixes that by introducing
a bitcast when the GetGlobalOp is updated. It also introduces a new cast
folder to eliminate cast chains that are circular after this new bitcast
is inserted.

[DirectX] Resolve unreachable default branches in switch statements (#193592)
Add a legalization to resolve unreachable default branches in switch
statements. These are introduced when the
`CorrelatedValuePropagationPass` proves all cases of a switch are
covered, leaving the default as an unreachable block.
The default destination is replaced with either the common successor
block or the first switch case destination.
This was discovered from the following case:
https://godbolt.org/z/W7zE1GMT6, where we can see that the unrolling of
the outer loop is not successful and the switch statement with an
`unreachable` branch remains.

[compiler-rt] Improve ubsan-minimal runtime for GPU use (#193597)
Summary:
GPUs are resource constrained, and we don't want to incur too much
overhead for using the runtime over a trap version. Unlike the other
targets, we have cheap `printf` on account of all the complexity being
done on the host, so we use that directly instead of custom formatting.
Additionally, we split the main function out into a helper function.
Listing it as `[cold]` prevents spurious inlining that massively bloated
register costs (this is an error reporting mechanism so hopefully that's
not controversial).
In practice for some basic tests, This cuts the register usage by more
than half and the stack size is no longer dynamically sized. The only
stack I saw was for the PC relative checks. This could be lowered
further with more intelligent PC caching, but this is a good, minimally
invasive, start.

[CIR] Add `__attribute__((annotate(...)))` support (#193329)
Implement end-to-end (Dialect, CIRGen, Lowering) support for
__attribute__((annotate(...))) on functions and global variables.
Dialect:
- cir::AnnotationAttr (#cir.annotation<name = "...", args = [...]>).
- $annotations on cir.func and cir.global (ArrayAttr of AnnotationAttr).
FuncOp gets a custom parser/printer entry; for GlobalOp it's tacked onto
the assemblyFormat.
CIRGen:
- Annotations are attached as deferred entries in CIRGenModule and
flushed at end-of-TU so the most up-to-date ValueDecl wins (decl
annotations + def annotations both stick).
- emitAnnotationArgs uniques arg ArrayAttrs via FoldingSetNodeID so two
functions with identical args share one ArrayAttr (and one .args
constant in LLVM lowering).
- addGlobalAnnotations supports both GlobalOp and FuncOp paths,
including function-local statics (emitStaticVarDecl).
Lowering:
- CXXABILowering treats AnnotationAttr as legal (no ABI conversion).
- Direct-to-LLVM lowering filters the annotations attribute off
cir.func, then collects (sym_name, AnnotationAttr, loc) tuples
pre-conversion and post-conversion emits @llvm.global.annotations plus
the supporting strings/args constants in section "llvm.metadata" —
bit-for-bit comparable to OGCG. String constants and per-arg structs are
deduplicated; identical args ArrayAttrs share one .args global (an
improvement over OGCG's per-site copies).

[CIR] Fix remaining (part 2) FlattenCFG rewriter contract violations (#192503)
Fix all 17 remaining MLIR expensive pattern check violations in
CIRFlattenCFGPass. Found by MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS=ON.
Fingerprint violations (patterns modifying IR without notifying
rewriter):
- Use rewriter.replaceAllUsesWith() instead of direct
replaceAllUsesWith() in replaceCallWithTryCall (tests: invoke-attrs.cpp,
try-catch.cpp, try-catch-all-with-cleanup.cpp)
- Use rewriter.modifyOpInPlace() for removeCleanupAttr() in TryOp
flattening (tests: flatten-try-op.cir, flatten-cleanup-scope-eh.cir,
flatten-throwing-in-cleanup.cir)
IR verification failures (invalid intermediate IR after pattern
application):
- Expand nested op checks in Switch, Loop, CleanupScope, and TryOp
flattening to include all structured CIR ops (ScopeOp, IfOp, TernaryOp,
etc.), not just CleanupScopeOp. Break/continue/return inside nested
structured ops creates invalid cross-region branches when the enclosing
op hasn't been flattened yet (tests: switch.cir, loop.cpp,
cleanup-scope-return-in-loop.cpp, partial-array-cleanup.cpp, switch.cpp,
typeid.cpp, flatten-cleanup-scope-simple.cir,
flatten-cleanup-scope-multi-exit.cir)
- Relax CIR_ResumeOp ParentOneOf to include all structured ops, since
cir.resume can temporarily appear inside them during flattening (test:
new-delete-deactivation.cpp). Feels weird to do that, but extended
documentation to account for.
- Change loop region constraints from SizedRegion<1> to
MinSizedRegion<1> for cond/step regions, since cleanup scope flattening
inside these regions may create multiple blocks (test:
loop-cond-cleanup.cpp)

[mlir] Add analysis filter in dataflow solver (#192998)
Adds an optional filtering control function to the dataflow solver's
initializeAndRun callback, which controls which analyses will be
initialized when running the solver. This makes it possible to reuse
existing dataflow solver instances that have already run to a fixpoint
without re-initializing all of the analyses that have already converged.
A new analysis and test pass is also added, which illustrates how the
filtering can be useful to run a staged analysis, which would not have
been possible before. The example analysis, called `BarAnalysis`,
depends on the converged state of the `FooAnalysis`. The Bar analysis is
a forward analysis that tracks, for each program point, whether any of
the preceding program points hold a `foo_state` that is divisible by 4.
In the example test, the control flow graph looks like the following:
```
entry-block
/ \
bb0 bb2
\ /
bb1
```
The `foo_state` of `bb1` depends on the `foo_state` of `bb0` and `bb2`.
If the solver goes through `bb0->bb1` before `bb2->bb1`, then there is
an intermediate stage in the analyses where the state of `bb1` could be
divisible by 4, even though the final state of `bb1` will not be
divisible by 4 in the converged state. If the `BarAnalysis` runs on
`bb1` in this intermediate state, then it will get stuck with the
"divisible by 4" state, and the analysis will not yield the desired
results.
This PR ensures that the `BarAnalysis` will see the correct state
`foo_state`, because the `FooAnalysis` will fully run to a fixpoint
before the `BarAnalysis` is loaded, initialized, and run.
The Foo and Bar analyses are just trivial examples, but this pattern is
useful when there are analyses that can be made more effective by using
complementary analyses like integer range/divisibility analyses.
**Note for integration:**
DataFlowSolver::load now stores the concrete analysis TypeID, exposed
via DataFlowAnalysis::getTypeID(). Downstream DataFlowAnalysis
subclasses defined in anonymous namespaces must add
MLIR_DEFINE_EXPLICIT_INTERNAL_INLINE_TYPE_ID(ClassName) to their class
body.

[LoopVectorize] Don't replace widen with replicate for ExtractValueInst (#193404)
VPWidenRecipe with an underlying ExtractValueInst stores the
ExtractValue's indices() as part of the recipe's "operands",
necessitating special handling (see VPRecipeBuilder::tryToWiden() and
VPWidenRecipe::execute()). This makes it incompatible with conversion to
VPReplicateRecipe, because VPReplicateRecipe's scalarizeInstruction()
may attempt to set each operand of the cloned ExtractValueInst, but the
indices cannot be set via setOperand().
This patch works around the issue by preventing the conversion of
ExtractValueInst-based VPWidenRecipe to VPReplicateRecipe.

This PR adopts the following strategy for emitting optimization remarks

- Emit passing optimization remarks any time we decide to unroll.
- Only emit missed optimization remarks if the user explicitly requested
unrolling and we aren't able to honor their request.
- Only emit passing or missed optimization remarks when we're certain
that unrolling will succeed or fail.
- In lieu of emitting more informative passing/failing optimization
remarks when unrolling may still fail/pass, emit analysis optimization
remarks so users can understand the reason as to why unrolling may have
failed on that loop.

[lldb][Darwin] debugserver expedite new binary info, lldb use (#192754)
When lldb stops at the "new binaries loaded" internal breakpoint, it
must read the list of addresses of the new binaries out of process
memory, then send a jGetLoadedDynamicLibrariesInfos packet to
debugserver to get the filepath, uuid, and addresses of where all the
segments are loaded in memory.
It's possible for debugserver to find the "new binaries loaded" function
address in the inferior itself, recognize when it has stopped at a
breakpoint there, and expedite some/all of the information lldb is going
to ask for in the stop info packet that we send to lldb. This will make
big improvements to a large-batch-of-binaries loaded stop event, but
also focuses even more on the single-binary-loaded `dlopen()` use case,
which can be quite expensive when many binaries are loaded one by one.
This PR reduces the packet traffic for a new binary load notifications
by
1. When debugserver sees a thread that has hit a breakpoint, and the pc
matches the new-binaries-loaded function address, reads the list of
binaries that have been newly added and includes them in the stop info
packet (or the jThreadsInfo packet) in the `added-binaries` key. The
value is a list (array) of binary addresses.
2. If the number of binaries is small (today: one), debugserver may
collect the full information that jGetLoadedDynamicLibrariesInfos would
send back about it, and also expedite that in the stop info packet (or
jThreadsInfo) in the `detailed-binaries-info` key. This is a JSON
string, and the stop info packet is a semicolon separated series of
key-values, so it must be asciihex encoded, just like the `jstopinfo`
key. In the jThreadsInfo packet, the JSON for the binary information is
included in the response as-is as the value-dictionary.
3. If the remote stub doesn't provide these new keys, lldb will use the
same process as before. However, in
DynamicLoaderMacOS::NotifyBreakpointHit I was reading the load addresses
out of memory individually, with each binary having a 24-byte entry.
lldb's memory cache meant we read 512 bytes per 8-byte read, but when
1000 binaries were being loaded at process launch time, that was 24,000
bytes of VM that we would read in 512 byte batches. This patch changes
that to read the entire VM range that we will be accessing in one large
memory read (as large as the remote gdb RSP stub will support),
dramatically reducing packet traffic in that case.
4. debugserver needs to read the "new binaries loaded" function pointer
out of the "dyld_all_image_infos" structure in the inferior, and it is a
signed function pointer on arm64e processes, so debugserver needs to
strip off the signing bits before comparing the pc. I hoisted the strip
function out of DNBArchImplArm64 into DNBFixAddress(), and the only
complicated bit here is in DNBProcessAddrSize(), when an arm64e
debugserver is debugging an arm64_32 process on a watch. It's not a
common combination (mostly we will have arm64e debugservers debugging
arm64 processes, or arm64_32 debugservers debuggging arm64_32 processe),
but it is supported.
5. A very minor enhancement, I have debugserver now include a new key,
`sizeof_mh_and_loadcmds` in the full binary information that
jGetLoadedDynamicLibrariesInfos returns. When lldb needs to read a
binary out of memory, it needs to read the Mach-O header & load
commands, and it doesn't know the full size of that, so we end up doing
one read of the Mach-O header, then the header + load commands. I'm not
using this information in lldb yet, but I would like to, to improve
that.
At an implementation detail level, ProcessGDBRemote collects these two
new data from the stop packet / jThreadsInfo, and passes them to the
method that creates a new ThreadGDBRemote. I added two methods to the
Thread base class to retrieve the information. DynamicLoaderMacOS will
try to read the data from the thread that hit the "new binaries loaded"
breakpoint, and if the number of entries matches the number expected by
the register value, uses them. Else it falls back to fetching them the
traditional way. On an old debugserver that doesn't support these new
expedited fields, DynamicLoaderMacOS will get back a zero-length of
binary addresses and a null StructuredData dictionary for the detailed
image information, and behave as it always does. I tested this patch
with both the debugserver changes, and without.
Testing is clearly the big questionmark here - I added none. While
writing these patches, I had some bugs and the lldb testsuite on macOS
was very good at finding them, simply with our normal process launching
and dlopen'ing in our existing API tests. I could imagine a test that
would capture the packet log and try to ensure that the expedited
information is being used by lldb and we are not re-fetching the
information, though.

Originally, the smfmac verifier expects for the sparse indices, which
describe which the positions of the non-zero elements per lane, the
following:
```
8 bit source -> require vector<2xi16>, ABID range [0, 1]
16 bit source -> require vector<4xi8>, ABID range [0, 3]
```
which is correct for CDNA3 and what was stated in the CDNA4 ISA
description as well. However, because the CDNA4 variants have double K
of the CDNA3 variants, meaning e.g, for 16 bit variants, each lane
carries 8 non-zero values rather than 4, we need 16 bit sparse indices
to express the full range of non-zero elements. This is in line with the
layout tables presented in the CDNA4 ISA.
Direct comparison for 16 bit elements:
On gfx942; we can select from one of four 8-bit sets of sparse indices
with ABID. Each set represents the location of four non-zero values per
8 following 4:2 structured sparsity. For example:
```
a0 a1 0 0 a3 a4 0 0 | a5 a6 0 0 0 0 a7 a8 | a9 0 0 a10 0 a11 0 a12 | 0 a13 0 a14 0 a15 0
```
On gfx950; because each lane carries 8 non-zero values; we can only
specify the full range of 8 non-zero values per 16 from one of two
16-bit sets. For example:
```
a0 a1 0 0 a3 a4 0 0 a5 a6 0 0 0 0 a7 a8 | a9 0 0 a10 0 a11 0 a12 0 a13 0 a14 0 a15 0
```
Similarly, for 8 bit variants on gfx950, we would need the full 32 bits
to describe the full range of the locations for the 16 non-zero 8 bit
elements. In this case, there is no option to select from different sets
of indices.
The issue arises in downstream use cases if we want to use use a set of
sparse indices targeting gfx950; because we are unable to specify the
full range of the non-zero values at the moment, we will get numerical
issues.

[llvm] Implement the BPF ABI (#194031)
Implements BPFTargetInfo, the first target-specific ABI lowering for the

BPFTargetInfo mirrors the BPF ABI rules currently encoded in
`clang::BPFABIInfo` (clang/lib/CodeGen/Targets/BPF.cpp), but operates
entirely on `llvm::abi` types, keeping the logic frontend-independent:
- Empty aggregates and void returns are ignored
- Aggregates ≤64 bits are coerced to an aligned integer type
- Aggregates 65–128 bits are coerced to [2 x i64]
- Aggregates >128 bits and oversized _BitInt types are passed/returned
indirectly
- Promotable integers are sign/zero extended
- All aggregate returns are indirect
Also adds the `createBPFTargetInfo` factory function declaration to
TargetInfo.h.

- The legacy pass manager wrapper has been renamed to
AArch64StackTaggingPreRALegacy and updated to call the shared
implementation.
- The pass is registered in AArch64PassRegistry.def to make it available
to the New PM.

without any additional rewrites.

[llvm-profgen] Add support for ETM trace decoding (#191584)
This patch introduces ETMReader to llvm-profgen,
enabling the reconstruction of execution profiles from ETM formatted
trace data.
- Integrate OpenCSD (CoreSight Decoding Library) as an optional
dependency via the LLVM_ENABLE_OPENCSD flag.
- Implement ETMTraceDecoder in ProfileData to interface with OpenCSD.
- Implement ETMReader, which uses hardware configuration and ELF memory
mapping to decode instruction traces.
- Add the --etm command-line option to specify raw trace inputs.
- Add the --target-triple command-line option to override the target
architecture for the binary.
The implementation targets microcontroller-class (Cortex-M) devices
based on the binary's target triple.

[RISCV] Expand fcanonicalize on vector types (#193842)
This change does a couple of related things:
1) It changes the default expansion strategy for scalable
vectors for fcanonicalize. This switches us from
emitting a loop (directly parallel to unrolling)
to using the already available fmul expansion.
2) Mark RISC-V legal scalable vector types as Expand
to leverage the previous item.
3) Wrap fixed vector types in their corresponding
scalable types to avoid unrolling.
The net effect is to improve the lowering for fixed vector cases and to
no longer crash for the scalable ones. We were crashing because the
scalable cases were marked Legal, not Expand. We could have just fixed that, but doing everyone at once seemed like a good investment.
Note that we can also choose to follow Aarch64 and consider a vfmin
based lowering. I left that until later thought it is worthwhile noting
that's what we do for scalar code.

[lldb] Handle partial memory region coverage in IRMemoryMap::FindSpace (#194001)
FindSpace walks process memory regions to find addresses that won't
collide with the inferior's real memory. This is necessary even for
host-only allocations because the IR Interpreter works entirely in
inferior virtual addresses. IRMemoryMap remaps those addresses to read
from host memory instead of inferior memory, so overlapping ranges would
silently read the wrong data.
For WebAssembly, GetMemoryRegionInfo succeeds for the first region
(linear memory) but fails for addresses beyond it. The previous fix
(#193124) skipped the memory region walk entirely when `CanJIT()` is
false. However, as Jason points out, that removes the
collision-avoidance mechanism and risks overlapping with real inferior
memory.
Instead, handle the GetMemoryRegionInfo failure gracefully. If the
target can't describe memory beyond a certain point, treat the remaining
address space as unmapped and use it for the allocation. This preserves
the collision avoidance while avoiding the lldbassert.

[compiler-rt][WebAssembly] Use an int as CMP_RESULT (#194093)
LLVM uses an i32 as the default for `getCmpLibcallReturnType`, but
compiler-rt uses a word-sized integer by default. On most physical
hardware this happens to work because `i32` is largely ABI-compatible
with a word. On wasm64, however, they are not compatible so this causes
problems.
Resolve this by using `int` as the comparison result in compiler-rt.

Add checks to ensure that an alias and its target have compatible types:

- Issue a warning for mismatches in function types.
- Ignore type discrepancies for variables.
This behavior aligns with similar diagnostics in GCC.

Linux Kernel has removed scc.h header completely from the source code

https://github.com/torvalds/linux/commit/64edfa65062dc4509ba75978116b2f6d392346f5#diff-1ca78e598a5041ee51ae795d168435afad598b82a7a0ce80f215993589b96c7c
Without removing it, not only it breaks compiler-rt but also GCC build
since GCC always builds libsanitizer for linux targets.
After merging this we will need to cherry pick to GCC.

[LoongArch] Combine rounded vector shifts to VSRLR/VSRAR (#192921)
Add DAG combines to recognize canonical rounded shift patterns and lower
them to target-specific vector rounded shift instructions.
The combines match vector arithmetic and logical right shifts with
rounding implemented as:
```
add (srl/sra X, shift),
(and (srl X, shift-1), 1)
```
and the shift-by-1 variant:
```
add (srl/sra X, 1),
(and X, 1)
```
Additionally, handle the guarded form generated when shift may be zero:
```
vselect (setcc shift, 0, seteq),
X,
rounded_shift
```
and fold it to the corresponding rounded shift instruction.
Define new target DAG nodes VSRLR and VSRAR and add instruction
selection patterns for both LSX and LASX, including register and
immediate shift forms.

not non-template case.

[libc++] Fix constant_wrapper::operator() (#193573)
As Tomasz pointed out on mattermost,
given
```cpp
template <class T>
struct MustBeInt {
static_assert(std::same_as<T, int>);
};
struct Poison {
template <class T>
constexpr auto operator()(T) const noexcept -> MustBeInt<T> {
return {};
}
};
std::cw<Poison{}>(std::cw<5>);
```
This should work according to the wording
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2026/p3978r3.pdf
```cpp
template<class... Args>
static constexpr decltype(auto) operator()(Args&&... args) noexcept(see below);
```
```
- Let call-expr be constant_wrapper<INVOKE (value, remove_cvref_t<Args>::value...)>{} if all types
in remove_cvref_t<Args>... satisfy constexpr-param and constant_wrapper<INVOKE (value, remove_-
cvref_t<Args>::value...)> is a valid type, otherwise let call-expr be INVOKE (value, std::forward<Args>(args)...).
- Constraints: call-expr is a valid expression.
- Effects: Equivalent to: return call-expr;
- Remarks: The exception specification is equivalent to noexcept(call-expr).
```
so basically the spec says, there are two cases
- constexpr-param case
- runtime case
and if constexpr-param case works, uses it, otherwise fallback to
runtime case if it is valid, otherwise substitution error.
In this case, `std::cw<5>` satisfy `constexpr-param`, and
`constant_wrapper<Poison{}(5)>` is valid , it should just work. however,
our implementation implemented the two cases in two overload
```cpp
template <class... _Args>
requires(__constexpr_param<remove_cvref_t<_Args>> && ...)
_LIBCPP_HIDE_FROM_ABI static constexpr auto __call(_Args&&...) noexcept
-> constant_wrapper<std::invoke(value, remove_cvref_t<_Args>::value...)> {
return {};
}
template <class... _Args>
_LIBCPP_HIDE_FROM_ABI static constexpr auto
__call(_Args&&... __args) noexcept(noexcept(std::invoke(value, std::forward<_Args>(__args)...)))
-> decltype(std::invoke(value, std::forward<_Args>(__args)...)) {
return std::invoke(value, std::forward<_Args>(__args)...);
}
```
The logic is that, both overloads use return type SFINAE and the
constexpr-param case's concept is more constrained so it will be picked
first if constexpr-param case works.
However, in this example, the second overload's return type SFINAE
causes a hard error by the `static_assert` in the user code.
The fix is simply constrain the second overload and not using return
type SFINAE so it short circuits if constexpr-param case is valid.
As a drive by, removed the internal helper function and directly make
the public interface `operator()` two overloads so that we can apply
`[[nodiscard]]` on the constexpr-param case

[Clang][RISCV] Introduce OFP8(E4M3, E5M2) RISC-V vector types (#191349)
Currently there's no OFP8 scalar type supported in both clang and llvm
type system, the vector OFP8 RVV types are lowered to i8 llvm types for
now.
The reason to support only clang type is because of intrinsics
definition capability. If we make the clang type also using uint8 vector
types, it's not able to distinguish between E4M3 type and E5M2 type so
that we have to append additional type suffix to it.

This helps by avoiding the difficult predicate generation in scalar, using
natural extends to all-zero or all-ones in scalar as opposed to re-extending
them in vector registers.

now as other places can generate those nodes. performVP_TRUNCATECombine
needs to be updated to match the plain non-VP node when forming vaaddu.

[mlir][math] Add rounding modes to `math.fma` (#192839)
Rounding modes have recently been added for `arith` FP operations
(#188458). This commit adds rounding modes to `math.fma`, following the
same design as for `arith` FP operations.
If a rounding mode is present, the LLVM lowering produces
`llvm.intr.experimental.constrained.fma`.
In the absence of a rounding mode, the rounding behavior is deferred to
the target backend.

- **Note**: Moved theI nstruction Replacement Table and cross-function
cached maps as members of the Impl class.
- **Note**: Updated `InstReplInfo::RC` to be a pointer rather than a
stack object, because we're putting it into MRI
[here](https://github.com/llvm/llvm-project/blob/704c60fe9110256d2698d8e56b8c44ec5d1e733f/llvm/lib/Target/AArch64/AArch64SIMDInstrOpt.cpp#L532).
- Renamed existing pass with "Legacy" suffix and updated references
- Added NewPM pass AArch64SIMDInstrOptPass
- Updated pass type to `aarch64-simd-instr-opt` (prev:
`aarch64-simdinstr-opt`)
No existing `.mir` tests to update.

[clang] Make serenity.cpp more independent of the host (#193981)
Tests matching crt files previously relied on the host system not using
the same file paths as Serenity. This breaks on AIX, as both systems use
`/usr/lib/crt0.o`.
Redirect most tests to an empty sysroot so they match only on the
filename and remain independent of the host system. Also add a test that
verifies crt files can be found in a normal sysroot.

The compiler version was bumped in

include this. We should probably just hash pin the version in future
workflows for future toolchain upgrades.

what it should really be checking that the iterator is not the end
iterator. Fix this assert by introducing and using a variant of
vputils::findUserOf.

[BOLT] Support negative hex in pre-aggregated profile (#192391)
Handle signed values in parseHexField by falling back to int64_t parsing
when uint64_t fails. This allows pre-aggregated profile tools to use -1
for BR_ONLY, -2 for FT_EXTERNAL_ORIGIN, -3 for FT_EXTERNAL_RETURN.
Guard the external address reset loop in parseAggregatedLBREntry to
preserve sentinel values (offsets >= FT_EXTERNAL_RETURN).
Add tests for -1/-2/-3 in parseHexField and T entries with -1,
ffffffffffffffff, and buildid:-1 as BR_ONLY.

- r (FT_EXTERNAL_RETURN) records.
- B and T records using the negative -1 hex form (#192391),
which is parsed as the BR_ONLY/FT_ONLY sentinel.
- Error paths: invalid record type letter and malformed hex address
(perf2bolt is expected to exit non-zero with a parser error).
The two error-path inputs are tiny raw files under Inputs/ since they
contain intentionally malformed records that link_fdata doesn't process.

[MC] Always lower .fill to MCFillFragment (#194164)
Constant-count, constant-pattern .fill expands inline into the current
fragment via emitIntValue per byte, wasting both memory and time (a
redundant copy at MCAssembler.cpp). #50974 reports a 4s compile dropping
to 0.6s when the loop is removed.
Drop the inline path so .fill always becomes MCFillFragment.
This cannot be done before commit 507efbcce03d (2023) allowed
label differences to be separated by a MCFillFragment.
In directive_fill.s, the parse time warning is now diagnosed by
MCAssembler.

[MC] Drop MCTargetOptions parameter from MCTargetAsmParser (#194120)
Since #180464, MCAsmInfo holds the canonical MCTargetOptions.
The MCTargetAsmParser::MCOptions member is a redundant by-value copy,
which may have inconsistent values (llvm-exegesis passes a temporary
MCTargetOptions(), but this probably doesn't matter in practice; other
in-tree uses are correct).
Remove the field in favor of getParser().getContext().getTargetOptions,
and remove the MCTargetOptions parameter from the base ctor, all
subclass ctors, Target::createMCAsmParser, MCAsmParserCtorTy, and
RegisterMCAsmParser.

Two incompatible assembler syntaxes exist for symbol assignment:
```
sym = val -- accepted by most GNU assembler targets; rejected by
Hexagon, which interprets it as a mnemonic
.set sym, val -- accepted by Hexagon; rejected by Alpha, which
reserves .set for assembler mode flags
```
Switch all to `sym = val`, and opt out Hexagon to `.set sym`.

Summary:
Previously, `nvptx64--` would reject `nvptx64-unknown-unknown`. Two
options, either normalize all the triples in CMake, or just check the
architecture. I went with the former because it makes it easier for
people to pass different values.

[MC] Add MCTargetOptions to MCAsmInfo constructor. NFC (#194200)
Since #180464 the canonical MCTargetOptions pointer is stored in
MCAsmInfo, but it is bound after construction via `setTargetOptions`
called from TargetRegistry::createMCAsmInfo.
Direct constructions in unit tests can leave the pointer null, leading
to a runtime assert failure. Add MCTargetOptions to every MCAsmInfo
subclass constructor, store it as a reference in MCAsmInfo, and remove
`setTargetOptions()`.

[clang][bytecode] Add new IntegralType for function addresses (#194206)
We used to use just `::Address` for functions, which later caused
problems because we casted the pointer to `ValueDecl*` and passed it to
`Program::getOrCreateGlobal()`, which doesn't work of course.

[SLP] Fix spill-cost cache lookup and predecessor scan
A cached intra-block scan that stopped at a call or budget limit only
proves the sub-range below the stop point is call-free; do not reuse
the cached bit for queries whose First lies above it. Also switch the
cross-block predecessor scan to "exists a call-free backward path"
semantics, skip blocks strictly dominated by Root, and memoize only
the (Root, OpParent) key. Fixes a false-positive spill cost that was
blocking profitable vectorization.

Move the logic to validate FOR users and introduce the split directly to

It also means sinking only needs to be done once, instead for each
VPlan.

[InstCombine] Div ceil optimizations (#190175)
Relates: https://github.com/llvm/llvm-project/issues/187838
This PR improves handling of `div_ceil` from rust (which emits a div +
rem).
Currently, these three rust functions:
```rust
use std::hint::assert_unchecked;
#[unsafe(no_mangle)]
pub fn div_ceil_without_assume(x: u32) -> u32 {
x.div_ceil(7)
}
#[unsafe(no_mangle)]
pub fn div_ceil_with_assume(x: u32) -> u32 {
unsafe {
assert_unchecked(x <= u32::MAX - 7);
}
x.div_ceil(7)
}
#[unsafe(no_mangle)]
pub fn div_ceil_with_range(x: u32) -> u32 {
x.count_zeros().div_ceil(7)
}
```
Will emit this IR (cleaned up): The IR looks pretty good to me as both
the assert_unchecked and the popcount are providing range information.
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7

}

After running through opt and llc on main with popcnt for less noise:
`build/bin/opt -O2 -S < test.ll | build/bin/llc --x86-asm-syntax=intel
-mattr=+popcnt -O2 -o -`
```asm

(as a sidenote, just running llc seems to generate better code? I find
this a bit odd)
`build/bin/llc test.ll --x86-asm-syntax=intel -mattr=+popcnt -O2 -o -`
```asm

Anyway the llvm IR when run through opt at -O2:
On main:
The only changes I see are the urem being rewritten to a mul + sub for
all the instructions, and the range information is persisted but not
used.
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {

}
define noundef range(i32 0, 613566757) i32 @div_ceil_with_assume(i32 noundef %x) unnamed_addr {

ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 6) i32 @div_ceil_with_range(i32 noundef %x) unnamed_addr {
start:
%self = xor i32 %x, -1
%0 = tail call range(i32 0, 33) i32 @llvm.ctpop.i32(i32 %self)
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%d3 = udiv i8 %d.lhs.trunc, 7
%d.zext = zext nneg i8 %d3 to i32
%1 = mul i8 %d3, 7
%r4.decomposed = sub i8 %d.lhs.trunc, %1
%_6.not = icmp ne i8 %r4.decomposed, 0
%2 = zext i1 %_6.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %2, %d.zext
ret i32 %_0.sroa.0.0
}
declare void @llvm.assume(i1 noundef)
declare i32 @llvm.ctpop.i32(i32)
```
However, both the assume and the popcount provide range information so
we can do an optimization. Div_ceil is emitted as a udiv and urem. We
can combine them given the following rules:
Assuming you have floor division of X / Y, we can add Y - 1 to X and
floor division will always give us (floor_divide(X / Y) + 1) which gives
us the same result.
So the formula in general is:
```
div_ceil(X, Y) = X / Y + (1 if X % Y > 0 else 0) -> X + Y - 1 / Y
```
But this fails since I forgot about wrapping. So we need a condition
that X + Y - 1 does not wrap, and of course Y cannot be 0. Technically
we should ignore Y / 1 since that's a trivial identity.
That gets us:
```
add(udiv(X, Y), zext(icmp ne(urem(X, Y), 0))) -> udiv(add nuw(X, Y - 1), Y)
```
[Alive proof here](https://alive2.llvm.org/ce/z/nBvyv4)
This is where I thought I was done, because this should handle the range
and assume case (the assume case provides less information than the
popcount because popcount's range is narrower for X). So I thought I was
done.
Unfortunately this only optimizes one case (the assume case with the
wide code). The culprit here is in the popcount case, there's a trunc
for the popcount to bound it to an i8 since narrower arithmetic allows
for better optimizations before zero extending.
```llvm
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%d3 = udiv i8 %d.lhs.trunc, 7
%d.zext = zext nneg i8 %d3 to i32
%r4 = urem i8 %d.lhs.trunc, 7
%_6.not = icmp ne i8 %r4, 0
%1 = zext i1 %_6.not to i32
```
So we need to handle another form, when the udiv needs to be zexted to
the return type (because it was previously trunced, due to the
popcount).
```
add(zext(udiv(X, Y)), zext(icmp ne(urem(X, Y), 0))) -> zext(udiv(add nuw(X, Y - 1), Y))
```
[Alive2 Proof](https://alive2.llvm.org/ce/z/w7bRZW)
There was another oddity I found that trunced information wasn't passing
constant ranges, so I added that to ValueTracking.cpp to fix this fold
too.
On this branch the IR now transforms:
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7
%0 = mul i32 %d, 7
%r.decomposed = sub i32 %x, %0
%_4.not = icmp ne i32 %r.decomposed, 0
%1 = zext i1 %_4.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %d, %1
ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 613566757) i32 @div_ceil_with_assume(i32 noundef %x) unnamed_addr {
start:
%cond = icmp ult i32 %x, -7
tail call void @llvm.assume(i1 %cond)
%0 = add nuw i32 %x, 6
%_0.sroa.0.0 = udiv i32 %0, 7
ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 6) i32 @div_ceil_with_range(i32 noundef %x) unnamed_addr {
start:
%self = xor i32 %x, -1
%0 = tail call range(i32 0, 33) i32 @llvm.ctpop.i32(i32 %self)
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%1 = add nuw nsw i8 %d.lhs.trunc, 6
%2 = udiv i8 %1, 7
%_0.sroa.0.0 = zext nneg i8 %2 to i32
ret i32 %_0.sroa.0.0
}
declare void @llvm.assume(i1 noundef)
declare i32 @llvm.ctpop.i32(i32)
```
And we get this asm emitted:
```asm

[AArch64] Optimize vector fmul(sitofp/uitofp, 1/2^N) -> scvtf/ucvtf (#141480)
When a vector integer-to-float conversion is followed by a multiply with a
reciprocal power-of-two constant, we can fold both operations into a single
SCVTF or UCVTF instruction with a fixed-point shift operand.
For example, `fmul(sitofp(v2i32 x), <0.5, 0.5>)` becomes `scvtf.2s v0, v0, #1`.
This is a reworked version with several improvements over the original
submission:
- Rewrite the C++ operand matcher to share implementation with the existing
`SelectCVTFixedPointVec` (MOVIshift, FMOV, and DUP handling with correct
truncation for f16)
- Add `uitofp`/`ucvtf` patterns via a `CVTFRecipPat` multiclass
- Add full GlobalISel support (`GIComplexOperandMatcher` + renderer)
Supported vector types: `v2f32`, `v4f32`, `v2f64`, `v4f16`, `v8f16`.

lldb-dap: Fix race condition in event threads creation (#194012)
Move the registration of the SBListener to before
the event threads (`ProgressEventThread` and `EventThread`) start
This prevents a race condition where a stop event
could be missed if it was sent immediately after thread creation, which
would lead to a deadlock. It is most likely to happen under heavy CPU
load with test that fails early like
TestDAP_commands::test_command_directive_abort_on_error_init_commands.

[sanitizer] Fix race condition in GetNamedMappingFd with decorate_pro… (#190981)
…c_maps=1
Multi-threaded programs crash randomly when
ASAN_OPTIONS=decorate_proc_maps=1 is enabled due to filename collision
in /dev/shm.
Root Cause:
All threads use the same filename format '/dev/shm/<PID> [name]',
causing race conditions where one thread deletes a file created by
another thread, resulting in ENOENT errors.
Solution:
Add thread ID (TID) to the filename to ensure uniqueness:
- Old format: /dev/shm/<PID> [name]
- New format: /dev/shm/<PID>.<TID> [name]
This ensures each thread has a unique filename, eliminating the race
condition.
Testing:
- Original version: 30% crash rate (6 crashes in 20 runs)
- Fixed version: 0% crash rate (0 crashes in 50 runs)

[GVN] Propagate isMemorySSAEnabled() into ValueTable (#193938)
`GVNPass::runImpl()` calls `VN.setMemorySSA(MSSA)` with a single
argument. The second parameter of `ValueTable::setMemorySSA()`,
`MSSAEnabled`, defaults to `false`, so `ValueTable::IsMSSAEnabled`
remains false even when the pass is configured with
`-enable-gvn-memoryssa=1` or `-passes='gvn<memoryssa>'`.
The MemorySSA-backed value-numbering paths in
`ValueTable::lookupOrAddCall()` and `ValueTable::computeLoadStoreVN()`
are gated on `IsMSSAEnabled`, making them unreachable from runImpl() on
main today.
This patch forwards isMemorySSAEnabled() as the second argument to
setMemorySSA(), so selecting the MemorySSA backend actually enables
MemorySSA-aware value numbering.

AMDGPU: Back-propagate wqm for sources of side-effect instruction (#193395)
For readfirstlane instruction, as it would get undefined value if exec
is zero. To handle the case that only helper lanes execute the parent
block, we let the readfirstlane to execute under wqm. But this is not
enough. If the parent block was also executed by non-helper lanes, we
also need to make sure its sources were calculated under wqm. Otherwise,
if the instruction that generate the source of readfirstlane was
executed under exact mode, the value would contain garbage data in help
lane. The garbage data in helper lane maybe returned by the
readfirstlane running under wqm.
To fix this issue, we need to enforce the back-propagation of wqm for
instructions like readfirstlane. This was only done if the instruction
was possibly in the middle of wqm region (by checking OutNeeds).

scalar_to_vector for us. But on 32-bit targets, i64 isn't legal, and the
generic legalizer will end up emitting two 32-bit loads. This patch uses
f64 to avoid the splitting entirely and the redundant int->fp
conversion.

[NVPTX] Improve error diagnostic when handling unknown intrinsics (#191194)
Following up on #146726, it may be desirable to gracefully fail the
compilation in the presence of unknown NVVM intrinsics, which
cannot be lowered by the NVPTX backend, rather than silently
emitting invalid PTX.

[flang] only instantiate required symbols from parent modules (#193689)
Currently lowering is instantiating (creating
fir.address_of/hlfir.declare) for all module variables from host module
and submodules (for instance, in the new
host_module_variable_instantiation.f90 test, a fir.address_of was
generated the unused var2 inside the procedure foo).
This created a lot of noise (and in the worst cases, compile time
performance issues), and also some extra complexity at least for OpenACC
where the IR acc routine ended up referencing globals that are no
actually needed, creating the need to copy them on the GPU or to have
custom logic to ignore the globals.
This patch addresses this by doing a visit of the parse tree to detect
the required symbols and only instantiate those.

[MC] Take MCAsmInfo by reference in MCContext and TargetMachine. NFC (#194280)
Both MCContext::MCContext and TargetMachine::getMCAsmInfo treat
MCAsmInfo as a pointer that must be non-null. Make the contract
explicit:
* MCContext's constructor takes `const MCAsmInfo &MAI`.
* TargetMachine::getMCAsmInfo returns `const MCAsmInfo &`.
Make this change now since the MCContext ctor has recently been updated.

[AArch64] Sanitise pow inputs using a target DAG combine (#192958)
Sometimes we see LLVM IR like this:
%pow = call fast <4 x float> @llvm.pow.v4f32(...)
%fcmp = fcmp fast ...
%res = select <4 x i1> %fcmp, <4 x float> %val, <4 x float> %pow
where the pow intrinsic is called unconditionally, but only certain
lanes of the result are used. In fact, LLVM actively encourages code
like this due to the intrinsic being marked as safe to speculatively
execute. However, we know when using certain vector libraries like
ArmPL that this can be very costly if the unused lanes would take
the pow call down an expensive path. For example, if an input to
pow is a special value (inf, NaN, -0) then it triggers slow special
case handling, and ultimately the result is going to be ignored
anyway. For this reason we prefer to sanitise the pow input to
use 'safe' values when we know the result is going to be discarded.
The above example LLVM IR would then look like
%fcmp = fcmp fast ...
%sel = select <4 x i1>, <4 x float> splat(float 1.0), ...
%pow = call fast <4 x float> @llvm.pow.v4f32(<4 x float> %sel, ...)
%res = select <4 x i1> %fcmp, <4 x float> %val, <4 x float> %pow
where the value 1.0 is chosen due to the fact pow is known to always
return 1.0 for all powers.

[libc] Add struct cmsghdr and associated macros (#193756)
The macros are the main source of subtlety. The interesting aspects are:
- some implementations CMSG_ALIGN the size of struct cmsghdr, but this
is a noop. Instead of doing that, I added an assertion in the test.
- POSIX permits CMSG_NXTHDR to return null if the buffer has no space
for the data array, and this behavior differs between implementations.
This implementation does not do that in order to match CMSG_FIRSTHDR,
which doesn't have such an option.
- some implementations redirect the CMSG_NXTHDR macro to an (extern or
static inline) function. I implemented this inside the macro to avoid
having to define a (private ?) entry point for that function.

[AggressiveInstCombine] Fold split-width i32 cttz/ctlz patterns into wide i64 intrinsics (#192296)
This patch teaches `AggressiveInstCombine ` to recognize and fold common split-width i32 cttz/ctlz intrinsic calls into a single full-width i64
cttz/ctlz intrinsic.
For ex:
```
define i32 @src(i64 %val) {
%lo = trunc i64 %val to i32
%cmp = icmp eq i32 %lo, 0
%shr = lshr i64 %val, 32
%hi = trunc i64 %shr to i32
%cttz_hi = call i32 @llvm.cttz.i32(i32 %hi, i1 true)
%hi_plus32 = or i32 %cttz_hi, 32
%cttz_lo = call i32 @llvm.cttz.i32(i32 %lo, i1 true)
%result = select i1 %cmp, i32 %hi_plus32, i32 %cttz_lo
ret i32 %result
}
define i32 @tgt(i64 %val) {
%cttz64 = call i64 @llvm.cttz.i64(i64 %val, i1 false)
%result = trunc i64 %cttz64 to i32
ret i32 %result
}
```
and similarly for ctlz intrinsic.
Alive proof for the 2 folds added by this patch.

[memref] Simplify loads from reinterpret_cast of 1D contiguous memrefs (#188459)
Rewrite `memref.load` operations whose source is a `reinterpret_cast` that
represents a rank reshape of a 1D contiguous `memref` with a single non-unit
dimension.
Assisted-by: ChatGPT (refine implementation + tests). I reviewed all code and
tests before submission.
## Example
Before:
```mlir
%reinterpret_cast = memref.reinterpret_cast %src
to offset: [0], sizes: [1, 1, 999], strides: [999, 999, 1]
: memref<999xi64> to memref<1x1x999xi64>
%0 = memref.load %reinterpret_cast[%c0, %c0, %i]
: memref<1x1x999xi64>
```
After:
```mlir
%0 = memref.load %src[%i] : memref<999xi64>
```
## Motivation
This simplifies the IR, makes indexing explicit, and reduces indirection,
which in turn improves downstream transformations and lowerings (e.g. EmitC).
## Scope
This rewrite is intentionally narrow:
- Applies only to rank-expansion and rank-collapsing of a contiguous 1D buffer
(at most one non-unit dimension).
- Requires `reinterpret_cast` with zero offset and fully static sizes and
strides.
- Requires the non-unit dimension to be at a boundary (first or last).
- Requires any dropped indices (from size-1 dimensions) to be statically zero.
It does **not** handle:
- general `memref.reinterpret_cast` with arbitrary strides or offsets
- multiple non-unit dimensions
- cases where index dropping would change semantics
For example:
```mlir
%reinterpret_cast = memref.reinterpret_cast %src
to offset: [0], sizes: [1, 1, 1, 108], strides: [108, 108, 108, 1]
: memref<1x108xf32> to memref<1x1x1x108xf32>
%0 = memref.load %reinterpret_cast[%c0, %c1, %c0, %c0]
: memref<1x1x1x108xf32>
```
The pattern would skip `%c1` when forming the indices for the replacement load,
since it cuts the dimensions that were added to the left, including the
dimension where the non-zero index is:
```mlir
%0 = memref.load %src[%c0, %c0]
: memref<1x108xf32>
```
causing the rewrite to discard a non-zero index on a size-1 dimension, which is
not semantics-preserving.
## Correctness
In the accepted cases, the cast is a pure view that does not alter memory
layout. Size-1 dimensions do not contribute to address computation, and the
single non-unit dimension determines the access.
Dropping indices for size-1 dimensions (or inserting zeros when collapsing
rank) preserves the computed address. The rewrite is only applied when such
indices are statically zero, ensuring in-bounds semantics.
Therefore, the rewritten load is equivalent to the original load through the
`reinterpret_cast`

[Clang] No longer advertise support for coroutines on x86 windows. (#193456)
There are a large number of long standing issues with coroutines on
x86_32 windows as discussed here

- #59382
- #58556
- #58543
- #56989
- #193161
- #136481
As such this patches
- No longer defines `__cpp_impl_coroutine` on that platform
- Warn when using coroutines on that platform
The reason to not plainly error is that it would break too much valid
valid code, ie there are people who probably use coroutines sucessfully.
And we also want to keep testing on that platform, up until the point we
were to pull support completely.
Hopefully this is all temporary and someone will feel compelled to
improve the situation enough that we can unceremoniously revert this
patch.

[clang][CodeView] Prevent the input name from appearing in LF_BUILDINFO (#194140)
The implicit contract of an `LF_BUILDINFO` record (represented in LLVM
by
[`BuildInfoRecord`](https://github.com/llvm/llvm-project/blob/6f0b55ec55f3e5e1ccc0d6b0d04a307479218768/llvm/include/llvm/DebugInfo/CodeView/TypeRecord.h#L667))
is that its `CommandLine` field should not contain the input source file
— a separate `SourceFile` field is reserved for that.
When the command-line flattening was moved from `llvm/` to `clang/` in
#106369, the comparison value used to identify and strip the source
positional was switched from `MainSourceFile->getFilename()` (the full
input path resolved by clang) to `CodeGenOpts.MainFileName` (just the
basename, set via `-main-file-name`). As a result, when the driver is
invoked with an absolute source path the cc1 positional is that absolute
path and no longer matches `MainFileName`, so the source filename leaks
into `CommandLine` as a trailing positional cc1 argument.
This is a regression in Clang 20. It breaks downstream tooling such as
Live++, whose unity-splitting feature relies on the embedded command
line being the cc1 invocation minus the source. Reported in #193900.
This PR restores the previous behavior by passing the resolved frontend
input path(s) to `flattenClangCommandLine` and including them in the
equality check that strips the source positional. The basename match
against `MainFileName` is kept for the relative-input case. A regression
test (and a symmetric relative-path test) is added to
`clang/test/DebugInfo/Generic/codeview-buildinfo.c`.
Should fix #193900.

[HLSL] Handle logical pointer for array assign (#193227)
This commits adds SPIR-V testing on an existing test (almost-NFC on DXIL
testing). It also copies it and invokes Clang using the experimental
logical pointer flag.
Adding this flag shows a missing case in the frontend, handled with this
commit.
Due to the difference in index handling between the structured.gep and
legacy one, the Cbuffer load codegen had to be rewritten. It's a bit
more naive, as we get one gep per level, but this will be handled by
optimizations later on.

[MLIR][OpenMP] Remove Generic-SPMD early detection (#150922)
This patch removes logic from MLIR to attempt identifying Generic
kernels that could be executed in SPMD mode.
This optimization is done by the OpenMPOpt pass for Clang and is only
required here to circumvent missing support for the new DeviceRTL APIs
used in MLIR to LLVM IR translation that Clang doesn't currently use
(e.g. `kmpc_distribute_static_loop` ). Removing checks in MLIR avoids
duplicating the logic that should be centralized in the OpenMPOpt pass.
Additionally, offloading kernels currently compiled through the OpenMP
dialect fail to run parallel regions properly when in Generic mode. By
disabling early detection, this issue becomes apparent for a range of
kernels where this was masked by having them run in SPMD mode.

[MLIR][OpenMP] Support allocations of device shared memory (#150924)
This patch updates the allocation of some reduction and private
variables within target regions to use device shared memory rather than
private memory. This is a prerequisite to produce working Generic
kernels containing parallel regions.
In particular, the following situations result in the usage of device
shared memory (only when compiling for the target device if they are
placed inside of a target region representing a Generic kernel):
- Reduction variables on `teams` constructs.
- Private variables on `teams` and `distribute` constructs that are
reduced or used inside of a `parallel` region.
Currently, there is no support for delayed privatization on `teams`
constructs, so private variables on these constructs won't currently be
affected. When support is added, if it uses the existing

[OpenMP][OMPIRBuilder] Use device shared memory for arg structures (#150925)
Argument structures are created when sections of the LLVM IR
corresponding to an OpenMP construct are outlined into their own
function. For this, stack allocations are used.
This patch modifies this behavior when compiling for a target device and
outlining `parallel`-related IR, so that it uses device shared memory
instead of private stack space. This is needed in order for threads to
have access to these arguments.

[OpenMPOpt] Make parallel regions reachable from new DeviceRTL loop functions (#150927)
This patch updates the OpenMP optimization pass to know about the new
DeviceRTL functions for loop constructs.
This change marks these functions as potentially containing parallel
regions, which fixes a current bug with the state machine rewrite
optimization. It previously failed to identify parallel regions located
inside of the callbacks passed to these new DeviceRTL functions, causing
the resulting code to skip executing these parallel regions.
As a result, Generic kernels produced by Flang that contain parallel
regions now work properly.
One known related issue not fixed by this patch is that the presence of
calls to these functions will prevent the SPMD-ization of Generic
kernels by OpenMPOpt. Previously, this was due to assuming there was no
parallel region. This is changed by this patch, but instead we now mark
it temporarily as unsupported in an SPMD context. The reason is that,
without additional changes, code intended for the main thread of the
team located outside of the parallel region would not be guarded
properly, resulting in race conditions and generally invalid behavior.

[OMPIRBuilder] Add support for explicit deallocation points (#154752)
In this patch, some OMPIRBuilder codegen functions and callbacks are
updated to work with arrays of deallocation insertion points. The
purpose of this is to enable the replacement of `alloca`s with other
types of allocations that require explicit deallocations in a way that
makes it possible for `CodeExtractor` instances created during
OMPIRBuilder finalization to also use them.
The OpenMP to LLVM IR MLIR translation pass is updated to properly store
and forward deallocation points together with their matching allocation
point to the OMPIRBuilder.
Currently, only the `DeviceSharedMemCodeExtractor` uses this feature to
get the `CodeExtractor` to use device shared memory for intermediate
allocations when outlining a parallel region inside of a Generic kernel
(code path that is only used by Flang via MLIR, currently). However,
long term this might also be useful to refactor finalization of
variables with destructors, potentially reducing the use of callbacks
and simplifying privatization and reductions.
Instead of a single deallocation point, lists of those are used. This is
to cover cases where there are multiple exit blocks originating from a
single entry. If an allocation needing explicit deallocation is placed
in the entry block of such cases, it would need to be deallocated before
each of the exits.

Descriptions are updated to follow the format of most other operations

[Flang][MLIR][OpenMP] Add explicit shared memory (de-)allocation ops (#161862)
This patch introduces the `omp.alloc_shared_mem` and
`omp.free_shared_mem` operations to represent explicit allocations and
deallocations of shared memory across threads in a team, mirroring the
existing `omp.target_allocmem` and `omp.target_freemem`.
The `omp.alloc_shared_mem` op goes through the same Flang-specific
transformations as `omp.target_allocmem`, so that the size of the buffer
can be properly calculated when translating to LLVM IR.
The corresponding runtime functions produced for these new operations
are `__kmpc_alloc_shared` and `__kmpc_free_shared`, which previously
could only be created for implicit allocations (e.g. privatized and
reduction variables).

[Flang][OpenMP] Add pass to replace allocas with device shared memory (#161863)
This patch introduces a new Flang OpenMP MLIR pass, only ran for target
device modules, that identifies `fir.alloca` operations that should use
device shared memory and replaces them with pairs of
`omp.alloc_shared_mem` and `omp.free_shared_mem` operations.
This works in conjunction to the MLIR to LLVM IR translation pass'
handling of privatization, mapping and reductions in the OpenMP dialect
to properly select the right memory space for allocations based on where
they are made and where they are used.
This pass, in particular, handles explicit stack allocations in MLIR,
whereas the aforementioned translation pass takes care of implicit ones
represented by entry block arguments.

[MLIR][OpenMP][OMPIRBuilder] Improve shared memory checks (#161864)
This patch refines checks to decide whether to use device shared memory
or regular stack allocations. In particular, it adds support for
parallel regions residing on standalone target device functions.
The changes are:
- Shared memory is introduced for `omp.target` implicit allocations,
such as those related to privatization and mapping, as long as they are
shared across threads in a nested parallel region.
- Standalone target device functions are interpreted as being part of a
Generic kernel, since the fact that they are present in the module after
filtering means they must be reachable from a target region.
- Prevent allocations whose only shared uses inside of an `omp.parallel`
region are as part of a `private` clause from being moved to device
shared memory.

[AArch64] Enable Spillage Copy Elimination by default (#186093)
In times of high register pressure, the greedy register allocator can
emit large eviction chains that consist of many `mov` instructions. The
Spillage Copy Elimination pass handles this, by finding these chains and
decreasing their impact. Take a mov chain such as the following where
`x8` is used for an 8-byte Folded Reload:
```
mov x7, x6
mov x6, x5
mov x5, x4
mov x4, x3
mov x3, x2
mov x2, x1
mov x1, x30
mov x30, x8
< use x8 >
mov x8, x30
mov x30, x1
mov x1, x2
mov x2, x3
mov x3, x4
mov x4, x5
mov x5, x6
mov x6, x7
```
Becomes:
```
mov x7, x6
mov x6, x8
< use x8 >
mov x8, x6
mov x6, x7
```
This provides performance benefits for long mov chains, where we are no
longer needing to copy these values between registers.
This does introduce compile time regressions, as was originally noted in
the initial review. From my testing, this was around 0.17% on average
using LLVM Test Suite.

[InstCombine] Require one-use intermediate binop in foldBinOpShiftWithShift (#194341)
foldBinOpShiftWithShift rewrites
binop(shift(X,C) op Mask, shift(Y,C))
to
binop(shift(X+Y,C), Mask).
Both shifts are matched with m_OneUse, but the enclosing binop that
wraps (shift(X,C), Mask) is not. When that binop has additional users
the rewrite cannot eliminate the originals and only adds new
instructions. The reproducer in the issue shows this: a shared base
with several downstream consumers gets duplicated on each one, so the
fold grows the IR instead of shrinking it.
Wrap the outer m_c_BinOp in m_OneUse so the fold only fires when the
binop can actually be replaced. Mirrors the one-use discipline already
applied to both shifts in the same matcher.
Fixes #194007.

[Clang] prevent crash in delayed default-argument lambda captures (#176749)
Fixes #176534
---
This patch resolves a crash when parsing delayed default arguments that
contain lambda expressions.
```cpp
struct S {
void f(int x, int = sizeof([x] { return x; }()));
};
```
When late-parsing default arguments that contain lambdas, `Sema` builds
a `FunctionScopes` stack containing only the lambda scope
(`FunctionScopes.size()` equals 1), however, `tryCaptureVariable`
expects an enclosing function scope outside the lambda scope
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19473-L19474
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19518
Scope capture handling logic decrements `FunctionScopesIndex` to align
declaration contexts
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19696
and later relies on it when traversing and accessing outer scopes
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19522-L19524
preserving the function scope in the late-parsing path prevents invalid
traversal during lambda capture handling

[AMDGPU][MC] Permit unneeded VOPD mov operands to be non-zero (#194060)
Use ? instead of 0 in the tablegen definitions for VOPD containing
v_mov. This enables the instruction to be disassembled regardless of
what bits are in those fields, which helps diagnose broken code.
Previously, the disassembler would reject these.

[offload] Fix use of AsyncInfoWrapper's finalize function (#194098)
The expected use is to forward the error from the asynchronous
operation's issuing (e.g., launchImpl) directly into the
AsyncInfoWrapper::finalize(). The check of the error is already
performed inside that function. No need to forward a dummy success error
code.

[LiveDebugValues] Use std::sort for register sorting in collectIDsForRegs (#194339)
VarLocBasedLDV::collectIDsForRegs sorts a SmallVector<Register> using
array_pod_sort which is a thin wrapper around qsort. That shows up as a hotspot
in compile-time profiles under __GI___qsort_r.
Switching this to an explicit-comparator llvm::sort call, which takes the
std::sort path instead improves compile-time with no change to code-size.

[Attributor] Support SPIR-V address spaces (#192725)
Right now Attributor assumes that if the the target is a GPU is can use

address space, but that's not true in general, so add SPIR-V support,
which uses different values.
This fixes an instruction incorrectly being marked as dead and optimized
out for an OpenMP SPIR-V offloading example.

[lldbremote][NFC] Factor out code handling breakpoint packets (#192915)
This commit extracts the code handling breakpoint packets into a helper
function that can be used by a future implementation of the
MultiBreakpointPacket.
It is meant to be purely NFC.
There are two functions handling breakpoint packets (`handle_Z` and
`handle_z`) with a lot of repeated code. This commit did not attempt to
merge the two, as that would make the diff much larger due to subtle
differences in the error message produced by the two. The only
deduplication done is in the code processing a GDBStoppointType, where a
helper struct (`BreakpointKind`) and function
(`std::optional<BreakpointKind> getBreakpointKind(GDBStoppointType
stoppoint_type)`) was created.

[flang][semantics][openacc] Allow collapse clauses on do concurrent (#192488)
This PR generalizes the semantic checking for collapse clauses to work
on `do concurrent` and fixes two bugs exposed along the way:
- The first was that `collapse (n)` where n < the number of nested loops
was giving an assertion violation.
- The second was do concurrent index variables were causing an assertion
violation because they hadn't been declared before looking them up.
The lowering is implemented as a TODO which will happen in a following
diff.

[clang-format] Recognize more braced initializers (#192299)
new
```C++
a = {x * x, x * x};
```
old
```C++
a = {x * x, x *x};
```
Fixes #57442.
The patch makes the program treat a brace following an equal sign a
braced initializer.
The patch changes these tests.
- In UnderstandsSingleLineComments and CommentsInStaticInitializers, the
comment in the formatted code used to be on a separate line, now it is
on the same line as the brace. The new behavior is consistent with
comment in braced lists that are correctly identified. Here is the
code for it from the test LayoutCxx11BraceInitializers and the
function mustBreakBefore.
```C++
// In braced lists, the first comment is always assumed to belong to the
// first element. Thus, it can be moved to the next or previous line as
// appropriate.
verifyFormat("function({// First element:\n"
" 1,\n"
" // Second element:\n"
" 2});",
"function({\n"
" // First element:\n"
" 1,\n"
" // Second element:\n"
" 2});");
if (Right.is(tok::comment)) {
return Left.isNoneOf(BK_BracedInit, TT_CtorInitializerColon) &&
Right.NewlinesBefore > 0 && Right.HasUnescapedNewline;
}
```
- In FormatsBracedListsInColumnLayout, the style is configured to one
which allows a trailing comment in the first line.

[CodeGen] Fix incorrect index in rematerialization tracking (#194387)
When deleting the last rematerialization of a register, we should delete
the rematerializer's remat tracking map's entry that corresponds to the
index of the *original* register, not the rematerialized register.
The existing typo has no impact on correctness at the moment because
entries with rematerialized register indices are never created (so there
is nothing to erase), and having an empty set in a value does not break
any code invariant; it just wastes memory.

[Flang][OpenMP] Allow Fortran BLOCK construct inside WORKSHARE region (#193352)
**Problem**
Flang incorrectly rejects Fortran BLOCK constructs inside OpenMP
WORKSHARE regions. This fixes the semantic check to recursively validate
the contents of BLOCK constructs instead of rejecting them.
The Fortran BLOCK construct (F2008) is a transparent scoping wrapper
that does not affect execution semantics. When a BLOCK appears inside a
WORKSHARE region, the restriction on allowed statements should apply to
the contents of the BLOCK, not the BLOCK construct itself.
**Fix**
The function CheckWorkshareBlockStmts (check-omp-structure.cpp) loops
through each statement inside a WORKSHARE region and checks if it's
allowed.
Before this fix, it only recognized:
```
Assignments, FORALL, WHERE statements
OpenMP constructs (ATOMIC, CRITICAL, PARALLEL)
When it saw a Fortran BLOCK, it didn't recognize it and threw an error.
```
When we see a BLOCK construct, instead of rejecting it, we "look inside"
and check if the statements inside the BLOCK are valid. This is done by
calling the same function recursively on the BLOCK's contents.

[Clang][RAV] Visit components of __builtin_offsetof designators (#194122)
`RecursiveASTVisitor` previously only traversed the type operand of an
`OffsetOfExpr,` ignoring the field/identifier/base/array-index
components of the designator. This meant tools built on RAV (clang-tidy,
clangd, indexers, ...) silently missed every field reference inside
`__builtin_offsetof(T, a.b.c)`.
Add a `TraverseOffsetOfNode / VisitOffsetOfNode` pair following the same
pattern used for `ConceptReference`, `ObjCProtocolLoc`, and friends. The
`DEF_TRAVERSE_STMT` for `OffsetOfExpr` now invokes
`TraverseOffsetOfNode` for each component; array index expressions
continue to be reached via the existing children() traversal. Default
visitation is a no-op, so the change is opt-in for consumers and
behavior-preserving otherwise.
Also expose `OffsetOfNode` as a `DynTypedNode` kind via `ASTTypeTraits`
so that downstream machinery (`SelectionTree`, parent maps, matchers)
can reference these nodes uniformly.
The same gap exists for Designator inside `DesignatedInitExpr` and can
follow this recipe in a follow-up.
Related: https://github.com/llvm/llvm-project/pull/192953. The current
PR enables precise component resolves in clangd (support to be added in
a followup).

not clear from the naming. This change
- introduces the hw-mode dependent register class `GxRC`, and the
associated register operands
- removes register class `ptr_rc_idx_by_hwmode`, and replaces the only
use with `gxrc`
- uses the `EQV` instruction as an example how to use the new class

[PowerPC] Simplify implementation of atomis loads (#191044)
The code for atomic loads is verbose. There are 10 different operations
and 4 memory sizes to support, which means 40 pseudo instructions are
used, with all the details repeated. This PR changes the following:
- Use a loop over the operations and the sizes to create the pseudo
instruction
- Adds the memory size as last operand to the pseudo instruction
- Updates the C++ code to take advantage of the memory size in the
pseudo instruction

[WebAssembly] Support f16x8.demote_f32x4_zero (#193564)
Add support for the f16x8.demote_f32x4_zero instruction. This
instruction converts a v4f32 vector to a v4f16 and pads the result with
zeros to fill the 128-bit register.
This enables efficient lowering of fptrunc operations from v4f32 to
v4f16 when the result is zero-extended or when only the low lanes are
needed. A DAG combine is included to recognize these patterns and fold
them into the new instruction.

`__builtin_frexpf`, `__builtin_modf`, `__builtin_powi`, and related

handler in `emitBuiltinExpr`, which calls `createBoolToInt` /
`createIsFPClass`. This produced a `cir.cast` with an integer result
type when the actual return type is floating-point, failing CIR
verification.
Break out of the switch so these builtins fall through to the
`isLibFunction()` path, which emits them as regular library calls.

[CIR] Fix eraseOp assertion in TryOp flattening with unreachable handlers (#193615)
When a try block has catch handlers but no throwing calls, the handler
regions are unreachable and the TryOp is erased. However, ops inside the
handler regions may reference values that were inlined from the try body
into the parent block, causing an assertion in `eraseOp` ("expected that
op has no uses").
This drops all defined value uses from handler regions before erasing
the TryOp.

[Clang] Avoid an extra `FunctionPrototypeScope` for lambda trailing requires-clauses (#194068)
`ParseTrailingRequiresClause` currently always creates a synthetic
`FunctionPrototypeScope`. This is needed for ordinary function
declarators
whose prototype scope has already ended, but it is wrong for lambda
trailing
requires-clauses because they are parsed while the lambda prototype
scope is
still active.
The extra counted scope gives parameters in nested requires-expressions
an
incorrect function scope depth. Split the synthetic prototype-scope
setup from
the trailing requires-clause parser so the lambda path can parse the
clause in
the existing prototype scope.

[Offload] Make kernel dynamic memory handling more generic (#194403)
Make sure we do not get unexpected NumThreads and NumBlocks values when
launching non-bare kernels, and generalize the computation of the
dynamic block memory allocation to handle multi-dimensional blocks.
The DynBlockMem fallback is never used in a non-bare context where
`NumBlocks[1]` and `NumBlocks[2]` are not 1 so the code was correct, but
this patch makes sure that assumption is made explicit, and also
future-proofs the code in case we decide to allow multi-dimensional
blocks for fallback dyn block mem in some path.

[DirectX] Add DXILDebugInfo pass (#191254)
The pass is enabled for DXILBitcodeWriter and ValueEnumerator to
transform LLVM IR and provide data required to lower it to DXIL.
There are 3 ways how DXILDebugInfo pass can change lowering to DXIL:
1. Transform LLVM IR directly in DXILDebugInfoPass::run. This works well
when the target IR does not break any invariants of LLVM IR.
2. Add extra metadata for ValueEnumerator to process with MDExtra map.
When ValueEnumerator enumerates a Key of MDExtra, it also follows the
Value and all its operands.
3. Replace a metadata for ValueEnumerator with a another metadata. When
ValueEnumerator enumerates a Key of MDReplace, or when the writer uses
getMetadataID, the corresponding value of MDReplace map is returned
instead.

[AsmParser] Revamp how floating-point literals work in LLVM IR. (#190641)
This adds support for the following kinds of formats:
* Hexadecimal literals like 0x1.fp13
* Special values +inf/-inf, +qnan/-qnan
* NaN values with payloads like +nan(0x1)
Additionally, the floating-point hexadecimal format that records the
bitpattern exactly no longer requires the 0xL or 0xK or similar code for
the floating-point type. The current hexadecimal syntax is retained for
the moment, but it is expected to be ripped out after the next release
of LLVM.
These changes were discussed in an RFC at
https://discourse.llvm.org/t/rfc-floating-point-literals-in-llvm-ir/82974.

[SLP]Bail out on non-schedulable expanded binop with multi-use operand
In tryScheduleBundle's DoesNotRequireScheduling path, an expanded binop
(shl X, 1 modeled as add X, X) doubles the dependency count of the
duplicated operand. Unlike the regular scheduling path, this branch does
not clear stale operand ScheduleData dependencies, so when that operand
has more uses than this bundle member the schedule's decrement count
exceeds calculateDependencies' increment count and UnscheduledDeps goes
negative, hitting "Expected valid number of unscheduled deps".
Fixes #194303.

[lldb] Fix has_lldb_codesign check (#194412)
I met a problem with this test on WSL. WSL has access to Windows's
files. Windows distribution has `security` dir (
`/mnt/c/Windows/security` from WSL point of view). So when we try to run
`security` command we get `PermissionError` instead of
`FileNotFoundError`. It is would not be a problem, but Python firstly
calls decorators for methods (see example below), so we call
`has_lldb_codesign()` not only on Darwin platform. Also I think some
Linux distros might have `security` command, so the current check is not
robust enough.
```python
import unittest
def checker():
raise Exception("test")
@unittest.skipUnless(False, "")
class Tests(unittest.TestCase):
@unittest.skipUnless(checker(), ())
def test():
pass

`gpu.async.token` operand). When the IR contained `gpu.launch_func`, the
dialect-conversion framework picked the structural pattern, silently
dropping the event record. The `async.execute` then yielded a stream
pointer where its consumers expected an event, and the host await ended
up calling `cuEventSynchronize` on a stream pointer. That call returns
an error without waiting, so the host raced against the GPU.
This change implements a fix which registers
`ConvertAsyncYieldToGpuRuntimeCallPattern` with pattern benefit 2 so it
wins on yields carrying `gpu.async.token` operands. The structural
rewriter still handles yields without token operands.
Also adds a new test `lower-async-to-gpu-runtime-calls.mlir` to check
the correct IR shape of `async.yield` after a `gpu.launch_func`.

[analyzer] Fix use-after-free in CheckerContext::getMacroNameOrSpelling (#194174)
This UAF bug was introduced 14 years ago, in 43de767b55c07.
The first use of this API was in
3b754b25bde4914e5ab693e7db9533c3260e926e, roughly around the same era.
It was dormant because the first param of `socket` and friends are
macros, and those didn't trigger this UAF.
I decided to go against adding a test because I figure that would be not
really meaningful.

[flang][cuda] Fix CUFDeviceGlobal duplicate skip and CUFAddConstructor for empty gpu.module (#194290)
**Fix 1:**
```fortran
module m
real, device :: a(3), b(3), c(3)
contains
attributes(global) subroutine kernel()
a(1) = 1.0
end subroutine
end module
```
When a kernel references global `a`, an earlier pass
(`CUFDeviceFuncTransform`) clones it into the `gpu.module`. When
`CUFDeviceGlobal` later processes all device globals, it finds `a`
already exists, and `break` exits the loop — skipping `b` and `c`
entirely.
Fix: Change `break` to `continue` in `CUFDeviceGlobal.cpp`.
**Fix 2:**
```fortran
module kernels_m
real, device :: dev_var
contains
attributes(global) subroutine my_kernel()
end subroutine
end module
program main
use kernels_m
end program
```
When a compilation unit USEs a CUDA module but defines no kernels
itself, the empty `gpu.module` is still registered with the CUDA
runtime, causing `cudaErrorNoKernelImageForDevice`.
Fix: Return early from the constructor if the `gpu.module` has no
kernels. Also skip variable registration for globals not in the
`gpu.module`.

The assertion in `flattenCatchHandler` required `end_catch` to be the

can have additional operations between `end_catch` and `yield`. The

Example:

For arrays with mixed constant and dynamic extents
(`!fir.array<?x4x?xf32>`), the allocation size only includes the dynamic
extents (`n * m * 4 bytes`), missing the constant extent `4`. This
under-allocates by a factor of 4, causing `cudaErrorIllegalAddress`.
Fix: After multiplying the dynamic extents, also multiply in constant
extents from the type, producing the correct size (`n * m * 4 * 4
bytes`).

__kmpc_reduce_nowait is passed as null to prevent the runtime from
selecting the tree reduction method for host, which carries a barrier.

[clang-tidy][readability-identifier-length] add structured bindings support (#193838)
This change extends the `readability-identifier-length` check to structured
binding declarations. Currently, only the names of regular variables,
function parameters, exceptions variables in catch blocks and loop
variables are checked. In other words, `int a = ...` warns but `auto [a]
= ...` does not.
This change enables the check to warn when the length of the names
introduced in structured bindings declarations is too short, following
the same rules as for the other kinds of declarations. Two new options
are introduced:
- `MinimumBindingNameLength` defines the number of characters below
which a warning is issued (the default it set to 2, like for loop
variables and exceptions variables)
- `IgnoredBindingNames` defines the names for which warnings should not
issued (by default, `_` is the only allowed exception)
To implement this feature, a new matcher is registered which matches all
the individual binding names. For example, in `auto [x, y] = ...`, it
matches `x` and `y` separately and the logic for determining if a
warning should be issued is applied independently to each binding name
introduced. Unlike the other matchers which return `VarDecl` nodes, this
new matcher returns `BindingDecl` nodes. The `utils::allDeclRefExpr`
helper function is modified to work for any `ValueDecl` node (the
closest common ancestor of `VarDecl` and `BindingDecl`) in order for the
line count threshold feature to work with this extension.

Allow DIBasicType (and others) to have a scope and location (#190217)
DIBasicType derives from DIType and so it already has slots to store the
scope and location of the type. However, the DIBasicType constructor
(and corresponding DIBuilder method) does not expose this, presumably
because it is not needed by C or C++.
In Ada it is more common to create one's own basic type. So, for Ada
exposing this functionality would be handy.
This patch adds a new overload of DIBuilder::createBasicType to allow
this. Because only Ada uses fixed point types, the patch simply updates
these DIBuilder methods unconditionally.
Note that DwarfUnit already handles this scenario and so no changes were
needed there.

[Clang] Emit LLVM flatten attribute instead of per-callsite alwaysinline (#188615)
Follow-up to #174899 which added the flatten function attribute to LLVM
IR and implemented recursive inlining in the `AlwaysInliner` pass.
This patch updates Clang to emit the LLVM flatten attribute on functions
with `__attribute__((flatten))`, instead of the previous approach of
marking each call site with `alwaysinline`. This completes the
transition to matching GCC's flatten semantics.
Changes:
- Remove the callsite `alwaysinline` annotation logic from CGCall.cpp
- Emit the flatten function attribute in CodeGenModule.cpp
- Update clang/test/CodeGen/flatten.c to reflect the new IR output
- Update clang/test/CodeGen/AArch64/sme-inline-callees-streaming-attrs.c
to reflect the new behavior
- Add release notes documenting the behavior change

[CIR] Implement static-local-tls lowering (#194059)
thread_local variables at function scope work very much like
static-locals, except with slightly different lowering from
cir-lowering-prepare. This patch implements that lowering. Global tls
variables are left to a later patch.
One decision I made here was that LocalInitOp lost its
'static-local'-ness, and assumes it is always static-local. Global TLS
is probably just going to use Global directly, so we don't need to to
permit it.
I DID leave it in the printing, as it makes it more clear what is
happening/for symmetry with get_global/global.

fix preserve_none in X86 backend (#192300)
This is a bug in the X86 backend affecting preserve_none with -O1. At
-O1, clang emits:
```
tail call preserve_nonecc void @_Z14func(ptr noundef nonnull byval(%struct.S) align 8 %1)
```
The `preserve_none` + `byval` never emitted the required caller-side
copy of the pointee. The callee received a pointer directly to the
original memory, violating the byval contract from LangRef: "a hidden
copy of the pointee is made between the caller and the callee, so the
callee is unable to modify the value in the caller".
The root cause is that CC_X86_64_Preserve_None in X86CallingConv.td had
no byval handling. As a result, byval arguments were falling through to
the register assignment rules and being assigned to registers instead of
stack slots.
The bug is fixed by one line in CC_X86_64_Preserve_None:
```
CCIfByVal<CCPassByVal<8, 8>>,
```
This ensures byval arguments are assigned to stack slots before the
register assignment rules are considered, consistent with all other
x86-64 calling conventions.

[CodeGen] Change -O0 bool load codegen to have nonzero model (#193783)
The main follow-up item to
https://github.com/llvm/llvm-project/pull/160790 was changing -O0
codegen to convert in-memory i8 bool values to i1 with the `nonzero`
rule (`icmp ne i8 %val, 0`) rather than the `truncate` rule (`trunc i8
%val to i1`).
Bool values can only be `true` or `false`. While they are notionally a
single bit, the smallest addressable unit is CHAR_BIT bits large, and
CHAR_BIT is typically 8. Programming errors (such as memcpying a random
byte to a `bool`) can cause the 8-bit storage for a `bool` value to have
a bit pattern that is different from `true` or `false`, which then leads
to undefined behavior.
Clang has historically taken advantage of this in optimized builds
(everything other than -O0) by attaching range metadata to `bool` loads
to assume that the value loaded can only be 0 or 1. This leads to
exploitable security issues, and the correct behavior is not always easy
to explain to C developers. To remedy this situation, Clang accepted a
[-fstrict-bool](https://discourse.llvm.org/t/defining-what-happens-when-a-bool-isn-t-0-or-1/86778)
switch to control whether it can assume that loaded bool values are
always necessarily 0 or 1. By default, it does (maintaining the status
quo), and users must specify `-fno-strict-bool` to opt out of that
behavior.
When opting out, users can optionally request that bool i8 values are
converted to i1 either by truncation or by comparing to 0. The default
is comparing to 0. However, since `-O0` alone _technically_ uses
-fstrict-bool, unoptimized builds convert i8 bool values to i1 with a
`trunc` operation, whereas `-O1 -fno-strict-bool` converts i8 bool
values to i1 with `icmp ne 0`. This is a surprising inconsistency.
This PR changes -O0 codegen to align with -fno-strict-bool. This is
achieved with a single-line change:
```
bool isConvertingBoolWithCmp0() const {
switch (getLoadBoolFromMem()) {
case BoolFromMem::Strict:
+ return !isOptimizedBuild();
case BoolFromMem::Truncate:
```
However, it impacts a _very large_ number of tests, so we agreed to move
it out of the -fstrict-bool PR to reduce the chances we would have to
back out the whole thing for this secondary item.
This PR does the change and modifies the tests accordingly. I expect
that it will go stale rather quickly. If this needs more discussion,
I'll only update it once we reach consensus.

[Sema] Enforce parameter match for ownership_returns attribute (#192339)
Previously parsing multiple ownership_returns attributes with different
arguments could lead to a crash. The documentation states that if
forward declarations have ownership_returns, they must have the same
arguments, and it may appear at most once per declaration.
This patch ensures that if multiple ownership_returns attributes are
present, their arguments (identifier and the optional index) must
exactly match. The diagonstic err_ownership_param_mismatch is introduced
for clarity.
Test cases for f15, C::f, and the newly added f22 were also updated to
match the requirement that all declarations of ownership_returns have
the same arguments, using the err_ownership_param_mismatch diagonstic.

[CIR] Eliminate SymbolTable::lookupSymbolIn hotspots (#193362)
mlir::SymbolTable::lookupSymbolIn is O(n) per lookup, so cumulative
symbol lookups during CIRGen are O(n^2) in the number of global symbols.
On template-heavy translation units this becomes a significant
compile-time hotspot.
Replace the SymbolTable lookup path with a per-CIRGenModule DenseMap
cache keyed by symbol name, giving O(1) lookups.
On a synthetic template-heavy stress test, end-to-end compile time on
`clang -fclangir -S -emit-llvm -O0` improves by ~11% on a 33K-LOC input
(5.86s -> 5.21s) and ~16% on a 67K-LOC input (16.09s -> 13.52s). The
super-linear growth of the win with input size confirms the O(n^2) ->
O(n) effect.
Similar to previous compile time fix, repro shape (scale records and
template instantiations into the hundreds/thousands to amplify):
template <typename T, int N> struct Box { T head; Box<T, N-1> tail; };
template <typename T> struct Box<T, 0> { T head; };
struct R0; struct R1;
struct R0 { int v; Box<int, 4> b; R1* next; };
struct R1 { long v; Box<long, 4> b; R0* next; };
int f0(R0*); int f1(R1*);
int f0(R0* r) { return r->v + (r->next ? f1(r->next) : 0); }
int f1(R1* r) { return (int)r->v + (r->next ? f0(r->next) : 0); }

[Offload][libsycl][clang-sycl-linker] Simplify SYCL Offload wrapping (#193876)
Replace the __sycl_tgt_bin_desc/__sycl_tgt_device_image-based fat binary
registration with a simpler OffloadBinary-native approach:
- __sycl_register_lib/__sycl_unregister_lib now take (BinaryStart, Size)
instead of a __sycl_tgt_bin_desc pointer; __sycl_unregister_lib only
needs BinaryStart since the runtime looks up the binary by its start
address.
- OffloadWrapper's SYCL wrapping is significantly simplified: the
__tgt_bin_desc/__tgt_device_image structs and the descriptor
construction code are replaced by a single embedded OffloadBinary blob
passed directly to the register/unregister entry points.
- clang-sycl-linker generates a single OffloadBinary, which contains
multiple images.
- ProgramAndKernelManager::registerFatBin parses the blob via
OffloadBinary::create, keying MDeviceImageManagers by BinaryStart to
eliminate the reparse on unregister.
- DeviceImageManager owns std::unique_ptr<OffloadBinary> instead of
borrowing a __sycl_tgt_device_image pointer; getRawData renamed to
getOffloadBinary.
- Introduce forEachSymbol and SymbolTable serialization
(writeSymbolTable/ SymbolTableHeader/SymbolTableEntry) in Utility.h to
expose the kernel symbol table embedded in the OffloadBinary "symbols"
section for consumption by the SYCL runtime.
- device_binary_structures.hpp reduced to DeviceBinaryTripleSPIRV64.

[lldb] Unify python shebangs (#187257)
As per PEP-0394[1], there is no real concensus over what binary names
Python has, specifically 'python' could be Python 3, Python 2, or not
exist.
However, everyone has a python3 interpreter and the scripts are all
written for Python 3. Unify the shebangs so that the ~50% of shebangs
that use python now use python3.

lldb] Fix two issues causing TestEvents.py flakiness (#194438)
This PR fixes two issues that contribute to `TestEvents.py` being flaky
in CI:
1. `ProcessEventData::DoOnRemoval` runs the full stop-handling logic
(like `ShouldStop` and `RunStopHooks`) every time an event is consumed
from any listener. When the primary listener consumes an event and then
the shadow listener consumes the same event, the logic runs twice. The
second execution can race with subsequent event processing. Fix this by
incrementing `m_update_state` after the first successful run so
secondary listeners skip the full logic.
2. Target::RunStopHooks updates `m_latest_stop_hook_id` (marking a stop
as "handled") before checking whether any threads have stop reasons. If
the check fails and hooks don't run, the stop ID is already consumed,
preventing hooks from ever running for that stop. Fix this by deferring
the update until we're certain we'll actually run hooks.

PR #181446 ("[asan] API for getting multiple pointer ranges") added five

compiler-rt/lib/asan/asan_interface.inc without updating
asan_abi_tbd.txt
or implementing them in compiler-rt/lib/asan_abi/asan_abi.cpp. This
broke
the AddressSanitizerABI-arm64-darwin ::
Darwin/llvm_interface_symbols.cpp
test, which diffs asan_interface.inc (minus asan_abi_tbd.txt) against
the
symbols actually exported by libclang_rt.asan_abi_osx.a.
List the new symbols alongside the existing __asan_get_report_* entries
so the stable-ABI test passes. The symbols remain unimplemented in the
stable ABI library; this change only reflects that they are
intentionally
not part of the stable ABI surface.

[InlineSpiller] Fix live-range update in hoisting within bb (#193880)
The InlineSpiller tries to shorten the live-ranges used when storing a
value that is defined by a sibling register by performing the following
transformation:
```
a = copy b
store a
```
=>
```
store b
```
That is, it eliminates the copy and store the original value at the copy
location.
As far as `b`'s live-range is concerned, this transformation is neutral
as long as the store is inserted in place of the copy being removed.
That doesn't hold when the copy is part of the basic block prologue. In
that case, the earliest insertion point for the store is after the
prologue:
```
a = copy b # part of bb prologue
... # more prologue instrs
store a <-- earliest insertion point
```
Therefore when this optimization kicks in and the copy is in the bb's
prologue, b's live-range needs to be extended to that insertion point.
This is exactly what this fix does.
Note: This issue is fairly easy to understand from an IR stand point and
one would expect a small reproducer.
Indeed, we would need only something that looks like:
```
a = copy b # prologue compatible copy
... # some more prologue instrs
... # high pressure point
= use a
```
The problem is the InlineSpiller optimization (implemented in
InlineSpiller::hoistSpillInsideBB) triggers only if `a` and `b` are
sibling registers, meaning they are the product of a live-range
splitting. Controlling live-range splitting is hard and I couldn't come
up with a smaller test case. The problem also disappears if we run
greedy alone because the live-ranges are repacked (well the slot indices
to be exact) compared to what the scheduler produces. That changes the
allocation order and the bug is not hit anymore.
The alternative would be to run the pipeline from the
coalescer/scheduler but that's not a whole lot more robust than the LLVM
IR path, plus the reproducer would be ~20k line long!
The other option (maybe something we should do in the long term) would
be to serialize/deserialize the VirtRegMap object so that we can set the
Virt2SplitMap map in a state that register a and b as siblings.

This should fix up the last DeclRefExpr LValue that appears other than
MSGuids and named global registers, both of which are specific to
individual attributes.

Reland "[clang][modules-driver] Add support for C++ named modules and import std" (2nd attempt) (#194475)
This reverts #193857 and relands #193312.
This adds basic support for explicit C++ named module builds, managed
natively by the Clang driver, including support for use of the Standard
library modules. This follows #187606, which adds the same for Clang
modules.
Current limitations:
- Standard library modules are still compiled to object files instead of
using the provided shared library. (This will be addressed in a
follow-up soon.)
- Caching is not supported yet (but likely to be added during the
upcoming GSoC cycle).
- Importing C++ standard library modules into Clang modules is not
supported (and not expected in the near term).

[CIR] Lower constant NTTP objects (#194496)
Like my previous patch, this just stores an NTTP object as a global
(using the same code, with 1 level of indrection slipped off), and
initializes it as a const. This patch also fleshes out the
CIRGenExprConstant.cpp area, leaving just 2 'NYI's in the area, 1 of
which is the MSGuidAttr again.

[RISCV] Improve getInterleavedMemoryOpCost for interleave groups with tail gaps. (#192074)
For interleaved access groups where gaps are only at the tail (i.e.
members are contiguous starting from index 0 but do not fill the entire
factor), the interleaved memory access pass can lower them to
vlsseg/vssseg intrinsics with NF equal to the number of group members
rather than the factor after #151612 and #154647.
Previously these groups fell through to the generic fixed-vector shuffle
cost model. This patch adds a dedicated cost path that checks legality
and estimates appropriate cost for them.
TODO: Support scalable vector type.
Fix #151497

[CIR] Implement PredefinedExpr in aggregate emitter and add consteval… (#194484)
… aggregate test
Handle PredefinedExpr by delegating to emitAggLoadOfLValue, removing the
NYI fallback. Also add a test for ConstantExpr aggregate emission
(consteval functions returning structs), which was already implemented
but lacked test coverage.
This unblocks ~206 libcxx test failures that involve aggregate
ConstantExpr and PredefinedExpr.
Note on LLVM IR divergence (will be addressed in follow-up PRs): For
consteval functions returning aggregates, CIR currently emits a global
constant + cir.copy that lowers to llvm.memcpy from the global, while
OGCG decomposes the constant into per-field stores. The added CIR / LLVM
/ OGCG CHECK lines in consteval-aggregate.cpp document this difference.
Convergence will come from a follow-up that decomposes the consteval
aggregate stores into per-field stores in LoweringPrepare (and related
GEP-index handling for padded structs).

This PR extends the DpasMx operation to support MXFP (microscaling
floating point) matrix multiply with separate scale factor layouts.
1. Op Definition
Added layout_a_scale and layout_b_scale attributes to DpasMx op
Removed AllElementTypesMatch<["a", "b"]> trait to allow different types
for A/B with scales
2. Layout Infrastructure
setupDpasMxLayout(): Creates anchor layouts for all 5 operands (A, B,
C/D, scale_a, scale_b)
Derives scale layouts from parent matrix layouts by dividing innermost
dimension
Supports all layout kinds: Subgroup, InstData, Lane
Fix a bug in getupDpasSubgroupLayouts(): sg_data of A/B matrix should
keep the full K dimension.
3. Layout Propagation
visitDpasMxOp(): Propagates layout attributes from op to operands during
dataflow analysis

[InstCombine] Reland #165975: Fix #163110: Support peeling off matching shifts from icmp operands via canEvaluateShifted (#190918)
This relanding of #165975 fixes the bug that caused the bootstrap-asan
buildbot failure
(https://lab.llvm.org/buildbot/#/builders/52/builds/16329).
## Original optimization
Consider a pattern like: `icmp (shl nsw/nuw X, L), (add nsw/nuw (shl
nsw/nuw Y, L), K)`
When K is a multiple of 2^L, this can be simplified to: `icmp X, (add
nsw/nuw Y, K >> L)`
This patch extends `canEvaluateShifted` to support `Instruction::Add`
and refactors its signature to accept a `ShiftSemantics` enum (`Lossy` /
`Unsigned` / `Signed`) instead of a bare opcode. This allows the
function to enforce losslessness requirements according to the overflow
flags (nsw/nuw) of the operands. The logic is wired into
`foldICmpCommutative` to fold `icmp (shl nuw/nsw X, C), Op1` into `icmp
X, (Op1 >> C)` when Op1 can be right-shifted losslessly by C bits.
## Bug fixed since #165975
`canEvaluateShiftedShift` unconditionally returned `true` for
same-direction logical shifts, ignoring the `ShiftSemantics` parameter.
This caused `foldICmpCommutative` to incorrectly transform:
`icmp uge (shl nuw X, 4), (lshr Y, 1) → icmp uge X, (lshr Y, 5) ← WRONG`
**Fix:** `canEvaluateShiftedShift` now returns `true` for same-direction
shifts only when `Semantics == ShiftSemantics::Lossy`, blocking the
unsafe fold for `Unsigned`/`Signed` semantics. Regression test added in
`Transforms/InstCombine/icmp_shl_lshr_fold.ll`.

making the constraint of this transformation stricter via an extra
isOperationLegalOrCustom guard on USUBO_CARRY. All other backends will
still receive generic lowering as implemented in the original patch.

[Flang][OpenMP] Clear close on descriptor members for box parents in USM (#194287)
Extend the MapInfoFinalization walk introduced in #185330 so
parent/member close consistency is enforced whenever
unified_shared_memory is in effect, not only when the parent map's
variable is a fir.RecordType. Allocatable (box) roots expand to member
maps the same way as derived-type instances; getDescriptorMapType may
add OMP_MAP_CLOSE to implicit descriptor members while the parent map
does not set close, which led to bad device behavior under
-fopenmp-force-usm with multiple mapped allocatables.

[clang-tidy] Fix UB in SuspiciousIncludeCheck when IgnoredRegex is not set (#194521)
When the "IgnoredRegex" option is not set, `IgnoredRegexString` is
default-constructed, i.e. initialized with a null data pointer. This is
passed to `llvm_regcomp` as the pattern argument, causing a nullptr+0 UB
in regcomp.c (caught by UBSan). Fix by initializing
`IgnoredRegexString` with an empty string literal instead.

[mlir][tosa] Make tosa-attach-target optional in addTosaToLinalgPasses (#193467)
addTosaToLinalgPasses unconditionally scheduled tosa-attach-target, thus
adding a `tosa.target_env` attribute to the module. Callers therefore
had no way to opt out of such attribute. This attribute is consumed if
validationOptions is enabled, which is optional. Therefore, if the
caller disables validationOptions, the tosa-attach-target attribute will
exist even after TosaToLinalg. So consumers that don't load the TOSA
dialect can't even parse the resulting module.
This PR makes sure that we schedule tosa-attach-target only when the
caller actually needs it, i.e. when validationOptions or
attachTargetOptions is set. The default values stay inside the
`!attachTargetOptions` branch so callers that set validationOptions
still get a target env to validate against, preserving existing
behavior.
Also add a `validation` pipeline option (default `true`) to the
registered `tosa-to-linalg-pipeline`, so it can be invoked without
scheduling either `tosa-attach-target` / `tosa-validate`. A lit test is
also added.

[LangRef][AMDGPU] Specify that syncscope can cause atomic operations to race (#189015)
Targets should be able to specify that the syncscope of atomic operations
influences whether they participate in data races with each other.
For example, in AMDGPU, we want (and already implement) the load in the
following case to be in a data race (i.e., return `undef` according to the
current definition), because there is an atomic store with workgroup syncscope
executing in a different workgroup:
```
; workgroup 0:
store atomic i32 1, ptr %p syncscope("workgroup") monotonic, align 4
; workgroup 1:
store atomic i32 2, ptr %p syncscope("workgroup") monotonic, align 4
load atomic i32, ptr %p syncscope("workgroup") monotonic, align 4
```
This is consistent with the behavior of, e.g., [heterogeneous-race-free (HRF)
memory models](https://research.cs.wisc.edu/multifacet/papers/asplos14_hrf.pdf) and the [HSA memory model](https://hsafoundation.com/standards/).

[X86] lock opt ptr const inconsistencies (#185195)
Resolves: https://github.com/llvm/llvm-project/issues/147280
The linked issue mentions cases of atomic arithmetic followed by a test
which can be recovered by flags that are emitting cas loops instead of
lock + op which can be inferred from flags.
There's one fold that solves the issue's code: `lock and` sets ZF on the
result of old & C, so any nonzero comparison against new = old & C can
be answered with ZF, so this fold does just that, reduces to a != 0 or
== 0.
I also decided to refactor `shouldExpandCmpArithRMWInIR` into a
dispatching function and make `getCmpArithCC` just return X86::CondCodes
directly. This deleted the dispatching switch later in the code.
Also I broke out the different cases of `getCmpArithWithCC` into helper
functions for each case (add, sub, and, xor, or, add with overflow, sub
with overflow) and turned them guard clause style to reduce nesting
since the original `getCmpArithWithCC` had everything in a nested
function which was hard to read. The functions are named so it's
straightforward to add new cases or move them around as desired.

[flang] improve array section analysis for WHERE (#194399)
The array section analysis in the HLFIR pass in charge of WHERE lowering
was unable to tell that the LHS and RHS are the same array section when
the base is an assumed shape or when a variable is used as indices.
This patch adds an optional callback to the array section
analysis to tell if two SSA values have the same value. This call back
is then implemented to tell that two SSA values are the same only if:
they are the result of equivalent operations with no memory effect (ok
to be non speculatable) and with operands that have the same value
(recursively), or if they are the load from the same variable (which is
OK in the context of WHERE RHS/LHS thanks to Fortran 2023 10.1.4 that
guarantee that a variable referred both on the RHS and LHS cannot be
modified by side effects in the RHS/LHS).

[AArch64][GlobalISel] Lower BF16 FPTRUNC (#193941)
When the architecture +bf16 features is available this is simple as we
lower to a standard instruction. When not available we need to expand to
a series of instructions that performs the necessary rounding. The code
to do that is a port of TargetLowering::expandFP_ROUND to GISel, minus
the float64 odd rounding via expandRoundInexactToOdd. f64 will follow in
a followup patch.
uitofp and sitofp are currently disabled, so that we can take this one
step at a time and check each part in turn. The LLT fp types attempt to
return true for ieee types without UseExtended for types of the correct
size, always returning false for non-standard types.

* Find `(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\."`
and replace with `$1"` using Visual Studio Code.
* Putting a call to `validate_diagnostic` in `AppendErrorWithFormat`.
* Manual inspection.
Note that this change *does not* include a call to `validate_diagnostic`
because I do not know what's going to crash on platforms that I haven't
tested on.

[InstCombine] Combine llvm.sin/llvm.cos libcall pairs into llvm.sincos (#184760)
Teach InstCombine to recognize pairs of `llvm.sin(x)` and `llvm.cos(x)`
intrinsic calls that share the same argument and replace them with a
single `llvm.sincos(x)` call, extracting the individual results.
The optimization works in two phases:
1. **SimplifyLibCalls**: Convert `sin`/`cos` C library calls (e.g.
`sinf`, `cosf`, `sin`, `cos`, `sinl`, `cosl`) into `llvm.sin` /
`llvm.cos` intrinsics when the call does not access memory (i.e. does
not set `errno`). This normalization step brings library calls into
the same form as compiler-generated intrinsics.
2. **InstCombineCalls**: When visiting an `llvm.sin` or `llvm.cos`
intrinsic, scan the users of the shared argument for a matching
counterpart. If found, emit a single `llvm.sincos` call placed right
after the argument definition, replace both original calls, and erase
the matched instruction.
Also remove the completed sincos TODO from Target/README.txt.

[Clang][AArch64] Fix codegen for SVE vector compare operations (#194013)
Overloaded operartors `<`, `>`, `<=`, `>=`, `==`, and `!=` with SVE
integer vector operands emitted LLVM IR with a couple of issues:
* The `icmp` instruction always performed unsigned comparison, even for
signed operands.
* The result of the comparison was zero-extended, whereas the intent is
to follow established NEON conventions and sign-extend it.
This patches fixes these issues.

[clang][test] Fix test failures when LLVM_WINDOWS_PREFER_FORWARD_SLASH is ON (#193156)
This commit addresses several test failures in Clang that occur on
Windows when
the CMake option -DLLVM_WINDOWS_PREFER_FORWARD_SLASH=ON is enabled.
Key changes:
- unit tests: Normalized expected paths to native style using
llvm::sys::path::native
(Basic/FileManagerTest, Frontend/ReparseWorkingDirTest) or updated
diagnostic matching
to be separator-agnostic (Driver/ToolChainTest).
- regression tests: Updated FileCheck patterns to use flexible regex
{{[/\\\\]}} or
{{[/\\\\]+}} to match both path separator styles.
- absolute-paths-windows.test: Skipped when forward slashes are
preferred because
mklink does not support forward slashes in directory paths and
interprets them
as command-line switches. Added 'windows-prefer-forward-slash' lit
feature.

[AsmPrinter][debug] Materialize abstract lexical blocks referenced by global vars (#193986)
After 63074da2 moved global variable emission from beginModule() to
endModule(), getOrCreateContextDIE() is called after abstract scope DIEs
have been built. However, skipLexicalScope() may have elided an abstract
lexical block that has no local variables. When a global variable (e.g.,
a function-scope static) is scoped to such a block,
getOrCreateContextDIE() returns nullptr causing an assertion. This PR
keeps abstract lexical blocks when they are the scope target of a global
variable in the compile unit.
Derived via LLM usage.

[NFC][analyzer] Refactor Environment to map Expr to SVal instead of Stmt to SVal (#193295)
Previously the `Environment` mapped `{Stmt *, LocationContext}` pairs to
symbolic values; but semantically it represents the values produced by
the evaluation of _expressions_, so there was no good reason to use
non-`Expr` statements in this mapping.
This commit replaces `Stmt` with `Expr` (its subclass) in this mapping
to accurately represent the actually relevant type.
This change is also propagated to methods, variables etc. that handle
the `Environment`.
There was a special case in `Environment::getSVal` that allowed looking
up a `ReturnStmt` in the `Environment` (and translated this to a lookup
of the "return value" sub-expression of the `ReturnStmt`). This commit
eliminates this and modifies the callers to explicitly look up the
sub-expression of the `ReturnStmt`.

[LoongArch] Support VBIT{CLR,SET,REV}I patterns for non-native element sizes (#193719)
Extend vsplat_uimm_{pow2,inv_pow2} matching to allow specifying an
explicit element bit width, enabling recognition of splat patterns whose
logical element size differs from the vector's native element type.
Introduce templated selectVSplatUimm{Pow2,InvPow2} helpers with an
optional EltSize parameter, and add corresponding ComplexPattern
definitions for i8/i16/i32 element widths. This allows TableGen patterns
to match cases such as operating on v8i32/v4i64 vectors with masks
derived from smaller element sizes.
With these changes, AND/OR/XOR operations using inverse power-of-two or
power-of-two splat masks are now correctly selected to VBITCLRI,
VBITSETI, and VBITREVI instructions instead of falling back to vector
logical operations with materialized constants.

[clang][bytecode] Don't start record field lifetime by default (#193496)
Even though we have per-field lifetime information we did not previously
diagnose this test:
```c++
struct R {
struct Inner { constexpr int f() const { return 0; } };
int a = b.f();
Inner b;
};
constexpr R r;
```
because the life time was started by default.
This patch makes record members be `Lifetime::NotStarted` by default
(unless they are primitive arrays) and then starts the lifetime when in
`Pointer::initialize()`.

[flang] allow rebox/embox of OPTIONAL (#194319)
Delay materialization of branches when building local temporary
descriptor for OPTIONAL from hlfir-to-fir until pre-cg-rewrite.
This makes the IR easier to analyze with OPTIONAL (for instance alias
analysis does not need to handle the branches to find the source).
This is done by adding an "optional" attribute to fir.embox, fir.rebox,
and fir.rebox_assumed_rank to indicate that their cogeneration must be
conditional.
The conditional aspect is implemented in pre-cg-rewrite to avoid
complexifying codegen and the fir.cg dialect.

[SPIR-V] Matrix in struct pointer legalization (#193073)
When looking to load an object at the start of a struct, the types do
not always match exactly. When we have an HLSL matrix the type in the
load will not match the type in memory. We need to improve the pointer
legalization pass to look for any "compatible" type at the start of an
aggragate.
A compatible are two types that the pass knows know to convert from one
to another.
This involves a refactoring of the code to make the check more general.

[SLP][NFC]Cache IsExternallyUsed by Value in cost computation
Same V is commonly seen in multiple TEs (shared scalars), and the
expensive part of IsExternallyUsed walks V->users() with multiple
match() pattern checks plus per-user getTreeEntries lookups - all
V-only-dependent. Split out the V-dependent body and memoize by
Value pointer, leaving the TE-specific copyable check at the call
site. DeletedNodes is read-only during the cost loop, so caching
is safe.

[AMDGPU][NFC] Remove redundant Args.size() assertions from AMDGPUMCExpr (#194488)
Remove redundant `Args.size()` assertions from `AMDGPUMCExpr` evaluate
functions (`evaluateExtraSGPRs`, `evaluateTotalNumVGPR`,
`evaluateAlignTo`, `evaluateOccupancy`).
These assertions are redundant with the `zip_equal` size checking
performed in the `evaluateMCExprs` helper function introduced in
#193859.

[Lit] Change processRedirects to open all files in binary mode (#194368)
This PR is the second in a series of patches upgrading Lit's in-process
built-ins to be able to run with piped input/output and full redirection
support, and to allow custom in-process builtns to be provided via the
Lit config. The remaining patches to Lit's test runner can be found here@
https://github.com/BStott6/llvm-project/compare/lit-inproc-builtins.
This is part of the Lit daemonized testing project:
https://discourse.llvm.org/t/88612.
This PR makes Lit's `processRedirects` function open all input/output
files in binary mode. This makes sure that in-process builtins have the
expected behaviour when reading and writing from them:
Newline translation is not required for any of the current in-process
built-ins, in fact, the in-process built-in for `echo`, which is the
only one that writes to `stdout`, explicitly re-opens the output file
with `newline=""` on Windows, to avoid newline translation. Also,
in-process builtins will eventually need to be able to read or write
binary data: for example, `opt` without `-S` running in daemon mode.
I believe this has no functional change for regular process invocations;
I have confirmed that programs invoked by Lit which write to files
opened in binary mode by Lit still have the newline translation
performed as normal on Windows, unless they change the mode of their
output stream themselves.

[Lit] Open sub-processes with text=`False` (#194577)
This PR is part of a series of patches upgrading Lit's in-process
built-ins to be able to run with piped input/output and full redirection
support, and to allow custom in-process builtns to be provided via the
Lit config. The remaining patches to Lit's test runner can be found here:
https://github.com/BStott6/llvm-project/compare/lit-inproc-builtins.
This is part of the Lit daemonized testing project:
https://discourse.llvm.org/t/88612
This PR makes Lit open all sub-processes with `text=False`, so that the
Python code will be able to read and write binary data to and from their
IO streams. This currently causes no functional change, as when Lit
reads output from the sub-processes, it already handles the case that
the read output is `bytes` by decoding it, but we will need to be able
to read binary data from a sub-process's STDIN if its output, which may
be binary, is piped into an in-process built-in, and we will need to be
able to write binary data to a sub-process's STDOUT if its input is
piped from an in-process builtin.
I have made sure that on Windows, when a sub-process invoked by Lit has
its output redirected to a file by Lit, the `\n -> \r\n` conversion is
performed as usual when writing to the file from the process - this
change only affects how the Python code interacts with the streams.

[flang][cuda] Preserve fir.rebox captured by cuf.kernel via CUDAKernelOpInterface (#193890)
Reland of #193837 (reverted in #193855), now using a marker op interface
to avoid the link cycle that broke `BUILD_SHARED_LIBS=ON` builds.
`SimplifyArrayCoorOp` folded `fir.rebox` into `fir.array_coor` across a
`cuf.kernel` boundary. CUF lowering needs the captured rebox to
materialize a managed-memory descriptor for the kernel; folding it away
makes the kernel dereference the host-side descriptor and crash with
`cudaErrorIllegalAddress`.
Fix is to add `fir::CUDAKernelOpInterface`, a marker op interface
defined in FIRDialect and implemented by `cuf.kernel`. The
canonicalization guard queries the interface, so the `TypeIDResolver`
symbol lives in `libFIRDialect.so` and no `FIR -> CUF` link edge is
introduced.

[OpenMPIRBuilder] Cast device num_threads to i32 for __kmpc_parallel_60 (#194634)
I observed a crash in device OpenMP lowering when compiling with
`-fdefault-integer-8`. In `targetParallelCallback`, `NumThreads` can be
`i64`, but `__kmpc_parallel_60` expects an `i32` `num_threads`
parameter, which caused a bad-signature assertion during call creation.
The fix is to use `CreateZExtOrTrunc(..., Int32)` for the `num_threads`
argument before building the runtime call. This matches the handling
used in clang in `CGOpenMPRuntimeGPU::emitParallelCall`.
The problem can be seen with the following testcase whe compiled with
`flang -fopenmp --offload-arch=gfx90a test.f90 -fdefault-integer-8``
```
program test
implicit none
integer :: nthreads
integer :: i
nthreads = 137

do i = 1, 1
end do
!$omp end target teams distribute parallel do

A variant of https://github.com/llvm/llvm-project/pull/176253 with a
change to reduce compile-time impact.
Since "llvm_unreachable" is actually allowed in constexpr functions,
simply emit the bodies of the selected functions in the header file.
In the previous PR the `isAllowedClauseForDirective` function was made
constexpr, but since it was very long it had a significant impact on
compilation time. In this PR that function is no longer constexpr.

[LLVM] Disable IO sandbox in symbolizeAddresses (#194597)
The function `symbolizeAddresses` is used by debugify to symbolize
addresses captured in the current invocation of LLVM, which it does by
executing llvm-symbolizer with temporary input and output files.
Creating the temporary files has an explicit sandbox exclusion, as
temporary files are necessarily not part of the compiler's formal
output, but attempting to read back the output file via MemoryBuffer
triggers a sandbox violation. Since we are always only operating on
temporary files within symbolizeAddresses, this patch disables the IO
sandbox in that function.

[LLVM] Fix use-after-free in AlwaysInliner flatten worklist (#194485)
Functions with both `alwaysinline` and `flatten` attributes were
collected into the `NeedFlattening` worklist, then erased during
always-inline processing, leaving dangling pointers. Fix by collecting
flatten functions after the always-inline loop, and eliminate the
separate worklist by iterating the module directly.

and other warning configuration.
Added regression test to make sure that diagnostic options are properly
applied in the fixit-recompile path.

[HIP][MacOS] Mach-O support and Darwin toolchain fixes (#183991)
This PR adds support for HIP on macOS: Mach-O section naming, Darwin
host toolchain initialization guards, and HIPSPV behavior when Darwin is
the host.
This has been verified using chipStar on MacOS via the PoCL OpenCL
implementation.
## Uninitialized target workaround
Darwin’s toolchain is only initialized when its own TranslateArgs runs.
For HIP/CUDA device jobs, Darwin is used as the HostTC and never gets
its args translated, so its target stays uninitialized. The new checks
avoid asserting on that uninitialized state. A better long-term fix is
to initialize Darwin earlier (see the FIXME in Driver.cpp
BuildJobsForAction).
- [ ] Initialize Darwin toolchain during construction instead of lazily
in TranslateArgs. See Driver.cpp BuildJobsForAction FIXME.
- [x] In Darwin’s addClangTargetOptions, skip host-stdlib flags when
DeviceOffloadKind != OFK_None so HIPSPV can safely delegate to the host.

- `Loop::setLoopMustProgress` (LoopInfo.cpp)
- `postUnswitch` partial/injection (SimpleLoopUnswitch.cpp)

[Clang] Simplify target specific implementations in gpuintrin.h (#194669)
Summary:
Previously we had a three-way dance where the top-level defined an impl
then the lower level defined potentially an override and then we
stitched those together.
This simplifies that, instead just defining a macro that says whether
or not we need it. This works because the target-specific portions are
always included first, so this basically says "Do we need to make a
default version".

[AArch64] Optimize lowering of i1 vector reduction (#187912)
This pr optimizes code generation in AArch64 for comparing bitcast <N x
i1> results with 0 or -1 using eq/ne. For scenarios where only "all
zeros or all 1s" are considered, the backend no longer prioritizes
materializing packed bitmasks and using vector reduction methods like
addv/umaxv/uminv. Instead, it expands the boolean vector into a regular
integer vector and performs the comparison via a more direct scalar
comparison path. For 64-bit and 128-bit cases that can be folded down to
64-bit, a lighter instruction sequence like fmov + cmp/cmn + cset/csel
is generated.
Functionally, this brings several benefits:
- Optimized the `setcc(bitcast(vNi1), 0/-1)` and
`select_cc(bitcast(vNi1), 0/-1, ...)` modes.
- In scenarios like <8 x i1>, a zero/all-one check can be performed
directly on the entire comparison result, avoiding additional vector
lateral reduction.
- In 128-bit scenarios like <16 x i1>, the vector is first folded using
ext + orr/and before a scalar comparison is performed.

[WebAssembly] Fix EHPadStack calculation in fixCallUnwindMismatches (#194184)
After #187484, `fixCallUnwindMismatches` now runs after
`fixCatchUnwindMismatches`. But `fixCallUnwindMismatches` was not
handling newly generated `try_table`s and trampoline BBs in
`fixCatchUnwindMismatches` correctly. See the comments for details.
This is mean to replace #192968 and adds its test case to
`cfg-stackify-eh.ll` and `cfg-stackify-eh-legacy.ll`. (The bug only
happens in the standard (exnref) EH so `cfg-stackify-eh.ll`, but I added
the same test to `cfg-stackify-eh-legacy.ll` as well for more coverage.)
`exception.ll`'s `inlined_cleanupret`'s results have changed because we
were generating unnecessary `try_table`s, thinking there were call
unwind mismatches when there weren't. (This wouldn't have resulted in
incorrect execution; it just added more unnecessary instructions.) This
also fixes some comments for `inlined_cleanupret`, because "throw_ref
targets the top level cleanuppad" is confusing. (This comment was
probably copy-pasted from "delegate targets ...".)
Closes #192968.

[CIR] Implement null check for CXXNewExpr (#192848)
When operator new is allowed to return null (e.g. nothrow new), the
initialization needs to be guarded by a null check,Previously this was
an errorNYI.
This wraps the initialization in a cir.if conditioned on the allocation
being non null, then uses cir.select to pick between the allocation
pointer and null as the result. Also removes
MissingFeatures::exprNewNullCheck.

A dependent member-pointer type doesn't necessarily have a class

This simplifies the check performed in a helper for diagnosing a cast

This fixes a regression introduced in
https://github.com/llvm/llvm-project/pull/132401, which landed in the
last release, and this will be back ported, so no release notes.

[clang] Fix interaction of __ob_wrap with signed divide. (#194474)
At first glance, signed divide overflow seems similar to other forms of
signed overflow, but it's significantly different: it's the only form of
signed overflow that is not affected by -fwrapv, it has undefined
behavior at the LLVM IR level, and it can trigger trap on x86.
Given that, make ubsan trigger on signed divide overflow even if a type
is marked __ob_wrap.

Fix #193892.
This is found during libc++ bringing up process. This patch:
- implement recursive mutex support for real.
- fix the issue that pthread mutex initializer and public mutex
interface misalign with internal representation. this was the root cause
that hangs the libc++ test as padding bytes effectively pollute the
futex state if default initializer was used.
- additionally, we changed the field to bitfield to allow encoding more
data. (e.g. the error checking flag that is not yet added). timed bit is
removed as we always support it anyway. PI bit is added instead.

[OpenMP] Fix use of uninitialized Dl_info when dladdr fails in ompd_init (#193643)
When dladdr() fails, dl_info is left uninitialized. The code printed the
error but then fell through to unconditionally call
strrchr(dl_info.dli_fname, '/'), accessing an uninitialized pointer --
typically NULL on the stack -- causing a SIGSEGV.
Fix by turning the second 'if' into 'else if', so the path-extraction
block is only reached when dladdr() succeeded and dl_info is valid.

[LLDB] Add module hook implementation (#185465)
Introduce a unified target hook command system for LLDB that handles
multiple target lifecycle events (module load, module unload, process
stop) through a single Hook class.
The existing target stop-hook commands remain unchanged for now, meaning
stop-hooks can now be created through either target stop-hook add or
target hook add -S.
A future follow-up can alias target stop-hook to the unified system to
consolidate the two paths.
New commands:
- target hook add [-o cmd] [-P class] [-u] [-S] - create a hook (fires
on module load by default, optionally on unload/stop)
- target hook add-filter [filter-opts] <hook-id> - attach stop-event
filters (shlib, function, file/line, thread) to an existing hook
- target hook list / delete / enable / disable - manage hooks
- target hook {enable,disable} {module-loaded|module-unloaded|stop-hook}
<id> - per-event toggling
top-event filter options live on a separate add-filter command rather
than on target hook add, keeping the add command clean and making the
system safe for filters on other event types.
Ran the tests + Made sure stop tests are passing as well.

[HLSL] Make load methods take const attribute (#193858)
Previously, HLSL shaders that declare a local resource const, cannot use
the `Load` method, since it is not attributed with const.
Load does not change a resource, it is a read-only operation, so the
method should be marked const.
This PR changes the methods so that they are marked const.

[AMDGPU][MIRFormatter] Printer & parser for S_WAITCNT human-readable mask (#193895)
This patch implements a printer and parser for the S_WAITCNT mask. It
prints the mask in a human-readable format, showing the counter values
like `Vmcnt_<NUM>_Expcnt_<NUM>_Lgkmcnt_<NUM>`.
The format matches the printing style of S_WAITCNT_DEPCTR. For example:
```
S_WAITCNT .Vmcnt_0_Expcnt_0_Lgkmcnt_0
S_WAITCNT .Expcnt_0
S_WAITCNT .AllOff
```
Counters at their maximum value (meaning "don't wait") are omitted. When
all counters are at max, `.AllOff` is printed.

[lldb] Define breakpoint location "." to mean the location(s) at which the current thread is stopped (#194272)
Adds `.` as a new `breakpt-id` syntax. Users can specify `.` to mean the breakpoint
location(s) that caused the current thread to stop.
I selected `.` to mean the current breakpoint locations for two reasons. In a shells,
period means <ins>current</ins> directory. In prose, a period is a <ins>stop</ins>.
My workflow often starts with multiple breakpoint locations, such as with regex
breakpoints, or basename breakpoints for overloaded/overridden names. As locations are
hit, I realize which locations are no longer needed. This new syntax makes it quick and
easy to disable the currently stopped location(s).
Another use case for this is to quickly repeat commands for the current location:
``` break com add -o 'p someVar' . ```
Usage example:
``` (lldb) b main.c:2 Process 47071 stopped * thread #1, queue =
'com.apple.main-thread', stop reason = breakpoint 1.1
frame #0: ... main`main at main.c:2:3
1 int main() {
-> 2 return 0;
3 }
Target 0: (main) stopped. (lldb) breakpoint disable . 1 breakpoints disabled. (lldb)
breakpoint list Current breakpoints: 1: file = 'main.c', line = 2, exact_match = 0,
locations = 1
1.1: where = main`main + 12 at main.c:2:3, address = ..., hit count = 1 Options:
disabled
```

This makes it less convoluted and more robust to when substeps fail. The

which is quite difficult to understand.

[WebAssembly] Print BB names better for CFGStackify debugging (#194187)
Currently, if a MBB does not have a corresponding original bitcode BB,
because it was generated later in the backend,
`MachineBasicBlock::getName()` returns an empty string. This adds
`getBBName` method, which prints BB names in the format of
`bb.3.catch.start` in case the original BB name is `catch.start`, and
just `bb.3` when there is no matching original BB, and uses it for
`LLVM_DEBUG` statements.

[git] [LLVM utils] Require `pyjwt[crypto]==2.12.1`, `cryptography==47.0.0`, and `urllib3==2.6.3` (#194707)
**Context:**
The MSVC team (👋 ) consumes the LLVM repo and is receiving security
alerts due to the git utils `requirements.txt` file requesting
transitive dependencies with known CVEs.
Namely, we're looking at the following CVEs:
- https://nvd.nist.gov/vuln/detail/CVE-2026-32597, fixed in
`pyjwt>=2.12.0`
- https://nvd.nist.gov/vuln/detail/CVE-2026-26007, fixed in
`cryptography>=46.0.5`
- https://nvd.nist.gov/vuln/detail/CVE-2026-21441, fixed in
`urllib3>=2.6.3`
**This PR** aims to address this re-computing the `requirements.txt` for
those dependencies, via:
> pip-compile --generate-hashes --upgrade-package pyjwt
--upgrade-package cryptography --upgrade-package urllib3
--output-file=requirements.txt requirements.txt.in
For auditability, I'm pasting my terminal session output below, so you
can see how the `requirements.txt` file was generated.

[bazel] Prevent bazel from scanning .git metadata (#194745)
This prevents race condition when git triggers its GC during a bazel
build. Bazel build fails as follows in that case:
```

[CIR] __builtin_source_location lowering for constant (#194505)
This handles the UnnamedGlobalConstantDecl lowering, which is only used
for the source-location object. This uses similar logic to the classic
compiler, so we end up with roughly the same IR.
There is a slight difference in how we choose which strings to uniquify
(preexisting) and how we name them/name duplicates, but it isn't really
relevant to the text itself.

[WebAssembly][GlobalISel] Migrate to extended LLT (#193047)
Moves Wasm GISel to use the the new extended LLTs added by #155107.
Extended LLTs have (optional) information about whether a particular
scalar is integer vs floating-point. This is a big win for Wasm, since
we can avoid a lot of guess work, and map LLT i32, i64, f32, and f64
directly to their Wasm counterparts.
To take full advantage of this, RegBankSelect has been automated,
iterating over all operands and mapping typed LLTs to their appropriate
register bank.

[CIR] Always set base subobject type for C++ records (#194504)
For unions and final C++ classes, computeRecordLayout previously left
the base-subobject type as a default-constructed (null) cir::RecordType.
The non-virtual size always equals the size for those kinds of records,
so no separate ".base" variant is needed, but `BaseSubobjectType` itself
was never set to the complete type either.
That null leaked through
getCIRGenRecordLayout(RD).getBaseSubobjectCIRType(), which is called by
getStorageType(const CXXRecordDecl *) when laying out a
[[no_unique_address]] / potentially-overlapping field. The null
mlir::Type was then stored as MemberInfo::data and tripped a
SmallVector::back() !empty() assertion in
CIRRecordLowering::fillOutputFields, because a member with null data is
interpreted as a bitfield placeholder and reads fieldTypes.back() that
was never pushed.
Match classic CodeGen (CGRecordLayoutBuilder.cpp) and unconditionally
set baseTy = *ty for any CXXRecordDecl, only constructing a separate
".base" record when nv-size != size (which excludes unions and final
classes by construction).
Reproducer:
```
union U { int a; long b; };
struct S {
[[no_unique_address]] U u;
int x;
} s;
```
This comes from a crash on the libc++ test-suite (~1,500 tests affected,
all crashing inside CIRRecordLowering::lower while laying out
__compressed_pair_padding-style structs in <string>).

[flang] Do not mark CUDA device variables as dso_local (#194500)
A follow-up to https://github.com/llvm/llvm-project/pull/189709.
```fortran
integer, constant :: zzz = 4
bind(c, name='zzz_from_c') :: zzz
```
In this code, `zzz` is a CUDA `constant` variable with an initializer.
With PIE enabled, flang marks it as `dso_local`, causing LLVM to emit
direct addressing (`leaq`) instead of GOT-indirect addressing (`movq
@GOTPCREL`). The CUDA runtime interposes on these symbols via
`cudaRegisterVar`, so the wrong address gets registered, leading to a
segfault.
Fix: skip `dso_local` for globals with a CUDA data attribute.

[RISC-V][RVY] Add a DataLayout component for CHERI capabilities
This adds a new pointer address space to the data layout when RVY is
enabled, making use of the new 'e' flag for pointers with
[external state](https://github.com/llvm/llvm-project/pull/105735).
I chose address space 200 since that is what has been used in the
downstream CHERI forks for the past decade and therefore makes it slightly
easier to upstream tests, etc. but am happy to use any other value if that
is preferred. We can look at the ABI name parameter to detect
pure-capability ABIs, so this does not support the "hybrid" CHERI case that
is supported downstream where capability registers are supported (i.e.
the AS200 pointer attributes exist in the data layout), but the default
address spaces are still integers instead of AS200.
to handle the "hybrid" case where only some pointers use Y registers.

[ORC] Move JITLinkMemoryManager ownership out of ExecutorProcessControl. (#192665)
Removes the JITLinkMemoryManager pointer and getMemMgr() accessor from
ExecutorProcessControl, replacing them with a
createDefaultMemoryManager() virtual factory method. This follows the
same decoupling pattern applied to DylibManager and MemoryAccess in
earlier patches.
JITLinkMemoryManager ownership moves to the client:
- LLJIT gains a MemMgr member and a MemoryManagerCreator builder hook.
- EPCIndirectionUtils takes a JITLinkMemoryManager& parameter.
- LinkGraphLinkingLayer and ObjectLinkingLayer lose their no-arg
constructors (MemMgr is now required).
- SimpleRemoteEPC::Setup is removed; custom memory manager selection now
happens at the client level rather than during EPC setup.

This reland incorporates the following fixes:
1) Change LLVM_ENABLE_OPENCSD to default to OFF (opt-in).
2) Parse the OpenCSD version from ocsd_if_version.h and gate OpenCSD
support on a minimum version of 1.5.4 to avoid compilation errors.
3) Refactor the test feature detection to use a
configure-time LLVM_HAVE_OPENCSD variable instead of runtime checks in
lit.local.cfg.

The rv32/rv64 here were the length of the vector types. The
rvp-ext-rv32.ll test has rv32 and rv64 RUN lines. Rename to make this
clearer.
I want to add rv32 RUN lines to the rvp-simd-64.ll, but we need to fix
some crashes first.

[mlir][xevm] Fix greedy rewriter crash in HandleVectorExtractPattern matches shuffles on block arguments (#192213)
`HandleVectorExtractPattern` could report `success()` without rewriting
the IR when `llvm.shufflevector` extracted a contiguous slice from a
**block argument** (no defining op). The greedy rewriter’s expensive
checks then aborted with *“pattern returned success but IR did not
change”*.
The pattern only performs work when the shuffle’s operand is defined by
another op (`FPExt`, `FPTrunc`, `bitcast`, nested `shufflevector`, or
`load`). For operands like function arguments, `getDefiningOp()` is
null, so nothing is rewritten; the function still fell through to
`return success()` without changing the IR and would crash when
`MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS` is on. `mlir-opt
--convert-xevm-to-llvm --split-input-file
mlir/test/Conversion/XeVMToLLVM/xevm_mx-to-llvm.mlir` no longer hits the
fatal error.

[AMDGPU][MC] update USER_SGPR_COUNT bits for GFX1250 (#192579)
When we work on the triton kernel with tensor descriptor created on the
host side, there is a error message `amdgpu_user_sgpr_count smaller than
than implied by enabled user SGPRs`.
After some debugging, we find the `USER_SGPR_COUNT` is not updated with
GFX125 and this patch updates it for USER_SGPR_COUNT from
https://llvm.org/docs/AMDGPUUsage.html#amdgpu-amdhsa-compute-pgm-rsrc2-gfx6-gfx12-table.
On GFX125, COMPUTE_PGM_RSRC2::USER_SGPR_COUNT is 6 bits wide. The MC
helper S_00B84C_USER_SGPR only masks to 5 bits; when the true user SGPR
count is 32 or more, the masked value wraps (e.g. 32 -> 0).
`AMDGPUAsmPrinter` then emits a .amdhsa_user_sgpr_count with 0, that
disagrees with the implied count from enabled user SGPRs (including
kernarg preload), and finally assembling llc output with `llvm-mc` fails
in `AMDGPUAsmParser`

[clangd] Resolve __builtin_offsetof designator components precisely (#194407)
Building on the new TraverseOffsetOfNode hook in RecursiveASTVisitor and
the OffsetOfNode DynTypedNode kind, teach SelectionTree, FindTarget, and
the explicit-references collector to address each designator component
individually. Cursor positions inside a nested designator (for example
the 'B' in __builtin_offsetof(A, B.c)) now resolve to the corresponding
field instead of always picking the innermost component.
- SelectionTree: wrap each OffsetOfNode visit in traverseNode so it
becomes a selectable node alongside its enclosing OffsetOfExpr.
- FindTarget::allTargetDecls: resolve OffsetOfNode (Field kind) to its
FieldDecl, and drop the OffsetOfExpr fallback so non-component
selections do not guess a field target.
- ExplicitReferenceCollector: emit one ReferenceLoc per component via a
new VisitOffsetOfNode hook, replacing the manual component loop in
refInStmt.
Tests:
- TargetDeclTest.OffsetOf: precise resolution for outer/inner/base/
identifier components, macro form, array index expressions, and
non-component selections.
- Hover.All and Hover.OffsetOfBuiltin: field cases for nested offsetof,
and expression hover on the builtin token.
- LocateSymbol.All: simple, outer, inner, macro, inherited-field, and
builtin-token cases.
- AllRefsInFoo: existing offsetof cases continue to pass via the new
per-component VisitOffsetOfNode path.

[flang] Avoid exponential traversal in deep type extensions (#191955)
`HasDestruction()` and `IsFinalizable()` walked component iterators that
already descend into parent scopes, and then also recursed through
derived-type components. With deep type extension chains, that caused
the same inheritance structure to be traversed repeatedly and compile
time to grow exponentially.
Iterate only over the current type scope instead. The scope contains the
type's own components plus its parent component, so the existing
recursion through derived-type components still handles inheritance
without double traversal.
Add a regression test with a deep type extension hierarchy.

[ThinLTO] Preserve Unicode characters in module paths when writing the combined-index (#194320)
`IndexBitcodeWriter::writeModStrings()` serializes module path strings
into a `SmallVector<unsigned>` before emitting `MST_CODE_ENTRY` records.
When a path contains UTF-8 bytes with the high bit set, appending from
`StringRef::begin()/end()` can be incorrect. Instead, append the module
path through `bytes_begin()/bytes_end()`, so the bitcode writer always
serializes unsigned bytes.

The various `findBounds` helpers (e.g. `findBoundsLT`) are suspected to
be incorrect because they do not account for potential integer overflow,
which can lead the dependence analysis to produce incorrect results.
Since these helpers are used by the BanerjeeMIV dependence test, this
patch disables BanerjeeMIV by default to avoid unsafe results and
progress the default enablement of DA. The Banerjee test is required for
our motivating example, and we will working on correctness issues and
reenabling it after default enablement.

The original symbol needs to be visited in the PFT so that it will be

use_device are treated in a special way in order to give them the DEVICE

When extracting from logicops, we often don't need to extract the result
if one of the element sources is identity (and(x,-1) -> x, or/xor(x,0)

peek through to an underlying build_vector.
I had hoped to make this generic, but there's still a lot of yak shaving
to deal with first, as usual - I've included the minimal x86-specific
fixes:
* missing constant folding of (vXi1 logicop(bitcast(c1),bitcast(c2)))
* fold kshiftr(concat_vectors(x,y,z,w),c) -> concat_vectors(z,w,0,0)

[SPIRV] Add missing OpenCL atomic_fetch_min/max builtin mappings (#190443)
## Summary
The SPIR-V backend maps OpenCL `atomic_fetch_add`/`sub`/`or`/`xor`/`and`
(and their `_explicit` variants) to SPIR-V atomic opcodes, but was
missing support for `atomic_fetch_min`/`atomic_fetch_max`, their
`_explicit` variants, and the legacy `atom_min`/`atom_max` builtins.
This caused OpenCL programs using these atomics to emit unresolved
function calls instead of the correct
`OpAtomicSMin`/`OpAtomicSMax`/`OpAtomicUMin`/`OpAtomicUMax`
instructions.
### Approach
Unlike add/sub/or/xor/and (which are sign-agnostic), min/max require
distinct signed vs unsigned SPIR-V opcodes. Rather than inspecting the
`OpTypeInt` signedness bit at runtime (which is always 0 in this
backend), this patch uses the existing prefix-based builtin lookup
mechanism in `lookupBuiltin`: the itanium demangler exposes the argument
type (`int` vs `unsigned int`), and the lookup adds an `s_` or `u_`
prefix accordingly, matching the correct `.td` entry.
### Changes
- **`SPIRVBuiltins.td`**: Add 12 prefixed `DemangledNativeBuiltin`
entries (`s_`/`u_` variants for `atomic_fetch_min`, `atomic_fetch_max`,
`atomic_fetch_min_explicit`, `atomic_fetch_max_explicit`, `atom_min`,
`atom_max`)
- **`SPIRVBuiltins.cpp`**: Add
`OpAtomicSMin`/`OpAtomicSMax`/`OpAtomicUMin`/`OpAtomicUMax` cases to the
`generateAtomicInst` switch to route these opcodes to
`buildAtomicRMWInst` (also fixes the pre-existing
`__spirv_Atomic{S,U}{Min,Max}` builtins that were defined in `.td` but
not handled in the switch)
- **New test**: `atomic_fetch_min_max.ll` covering all 6 builtins for
both signed and unsigned `i32` types

[clang][analyzer] Add support for detecting uninitialized dynamically-allocated objects
Adapt the allocated region into a `TypedValueRegion` by retrieving its
type and wrapping it in an `ElementRegion`.
The `willObjectBeAnalyzedLater` function must therefore fall back on
using `SubRegion`s.

[MLIR][GPU] Add cooperative launch support to gpu.launch_func (#190639)
Add a `cooperative` UnitAttr to `gpu.launch_func` that enables
cooperative kernel launch semantics. Cooperative launches guarantee that
all thread blocks in the grid are co-resident on the GPU simultaneously,
enabling grid-wide synchronization patterns.
## Implementation
When `cooperative` is set (with or without cluster sizes), the lowering
emits a call to the new `mgpuLaunchKernelCooperative` runtime function,
which uses `cuLaunchKernelEx` with a `CUlaunchConfig` and
`CU_LAUNCH_ATTRIBUTE_COOPERATIVE`. This API is guarded behind
`CUDA_VERSION >= 12000`. The HIP path funnels through
`hipModuleLaunchCooperativeKernel`.
## Changes
- **GPUOps.td**: add `cooperative` UnitAttr and assembly format keyword
- **SelectObjectAttr.cpp**: add `getKernelLaunchExFn()`, route
cooperative and/or cluster launches through `mgpuLaunchKernelEx`
- **CudaRuntimeWrappers.cpp**: implement `mgpuLaunchKernelCooperative`
via `cuLaunchKernelEx` or `hipModuleLaunchCooperativeKernel`, depending
on platform
- **GPUToLLVMConversion.cpp**: propagate cooperative attribute through
the legalization pattern
- **test/Dialect/GPU/ops.mlir**: round-trip tests for cooperative
keyword with and without clusters
## Context
MLIR currently has no support for cooperative kernel launches. Flang
works around this with a CUF-specific attribute (PRs #124325, #124362),
but there is no first-class support in the GPU dialect. This patch adds
it at the `gpu.launch_func` level so all frontends can use it.

[X86][FastISel] Restore support for struct returns (#194586)
After #180322, X86 FastISel forces SDAG fallback for any call with a
struct return. This caused major compile-time regressions for debug
builds in Rust, where struct returns are very common.
The type legality check should work on the de-aggregated types, not on
the return type directly.

[VPlan] Don't create sub(ext(mul(...))) partial reductions (#194660)
Currently if we have a loop that does a sub(ext(mul(...))) reduction
then createPartialReductions will try to transform it to a partial
reduction but then crash due to hitting an llvm_unreachable in
createPartialReductionExpression.
It looks like handling this in createPartialReductionExpression would
require adding a new expression recipe kind, so for now just don't try
to use a partial reduction so we avoid the crash.
Fixes #194000

[llvm-ir2vec] Place IR2Vec Python bindings in the tools/llvm-ir2vec/Bindings build directory (#194301)
## Place IR2Vec Python bindings `.so` in the Bindings build directory
Without an explicit output directory, CMake places the nanobind
extension module
in `<build>/lib/`, alongside unrelated LLVM libraries.
- This change adds `set_target_properties` to redirect the output to
`<build>/tools/llvm-ir2vec/Bindings/`, keeping the Python bindings
isolated within its own tool's build tree. This mirrors MLIR's
convention,
where Python extension modules are placed under
`<build>/tools/mlir/python_packages/` rather than the global `lib/`
directory.
- %llvm_lib_dir was pointing to build-llvm/lib but the .so actually
lives at build-llvm/tools/llvm-ir2vec/Bindings/. The tests were silently
passing only because the conda env's site-packages had ir2vec installed,
masking the broken PYTHONPATH entirely.
- Two changes:
- `lit.local.cfg` — replaced `%llvm_lib_dir` substitution with
`%ir2vec_python_dir` pointing to the correct build output path
- All 6 test `.py` files — updated the RUN line from
`PYTHONPATH=%llvm_lib_dir` to `PYTHONPATH=%ir2vec_python_dir`
