[libc] Fix modular printf attributes (#194003)
This fixes the validation error related to modular printf missing format attribute in C++ code by moving the validation after the implicit format attribute is added for builtins and known library functions.
This also adds a simple C++ test since the C code did compile successfully because the implicit attributes were added in time for the validation happening for C code.
Assisted-by: codex, reviewed and cross checked, also tested with ATfE,
by me. Modular printf reduced code size from ~37K to ~13K for int-only
printf sample.

[AArch64] Fix fmaxv/fminv/fmaxnmv/fminnmv/lasta/lastb sched info in A64FX (#198483)
I've been experimenting with a new TableGen warning on unused defs and
it found a couple bugs in the A64FX scheduling model [1]:
llvm/lib/Target/AArch64/AArch64SchedA64FX.td:2288:5: warning: def
'A64FXWrite_FMAXVD' appears to be unused
llvm/lib/Target/AArch64/AArch64SchedA64FX.td:2334:5: warning: def
'A64FXWrite_LAST_R' appears to be unused
It looks like similarly named defs were used where they should have been
and the microarchitecture manual [2] seems to confirm it.

[analyzer] Fix false positive in CStringChecker for offset buffer arg… (#198346)
…uments
CStringChecker::checkInit() was checking the wrong array elements when
the buffer argument pointed into the middle of an array (e.g.,
memcpy(dst, &arr[i], size)). It was called with BufEnd instead of
BufStart, making the ElementRegion index off by (size-1), and the
element lookups were relative to array index 0 instead of the actual
buffer start offset.

Reland "[AMDGPU] Account for inline asm size in inst_pref_size calculation" (#197227)
This relands commit 7ddee0b619f658cef905a69427ef9531fd1d229d (PR
#192306) which was reverted in 70a70e0ed664 (#197070) due to a missing
MC assembler parser case for the `instprefsize` MCExpr, breaking text
assembly roundtrip tests.
Fix:
- Add `"instprefsize"` to the `StringSwitch` in
`AMDGPUAsmParser::parsePrimaryExpr` so the MC assembler can parse
`instprefsize(...)` expressions emitted by `llc` in text assembly mode.
- Add roundtrip lit tests (`llc -filetype=asm | llvm-mc -filetype=obj |
llvm-objdump`) for both GFX11 and GFX12 to prevent regressions.
Confirmed by compiling the new lit test using the original commit that
it was failing and passes now.
_Original PR description_
> `SIProgramInfo::getFunctionCodeSize()` with `IsLowerBound=true` was
completely skipping inline assembly instructions, treating them as zero
bytes. This caused `amdhsa_inst_pref_size` to be severely underestimated
for kernels containing inline asm, defeating instruction prefetch on
gfx11+.
>
> Use MCExpr label subtraction (`.Lfunc_end - func_sym`) to compute
exact function code size, resolved at assembly time. Add a new
`AMDGPUMCExpr` variant (`AGVK_InstPrefSize`) to compute
`min(divideCeil(codeSize, cacheLineSize), maxFieldVal)`.
>
> Remove the `IsLowerBound` parameter from `getFunctionCodeSize()` as it
is no longer needed.

[MLIR][XeGPU] Avoid chained-reductions in multi_reduction unrolling (#198307)
The PR adds a new unrolling pattern for `vector.multi_reduction` to the
`xegpu-blocking` pass. In comparison with [the upstream reduction
unrolling](https://github.com/llvm/llvm-project/blob/2da84a8307e4ef729458d990b221650a5da22639/mlir/lib/Dialect/Vector/Transforms/VectorUnroll.cpp#L372),
the new pattern performs partial row-wise reductions via elementwise
ops, instead of generating a chain of several multi-reduction ops:
```mlir
// reduction to unroll:
// tile-shape: [8x16]
vector.multi_reduction <add> %vec, %cst : vector<8x48xf32> to vector<8xf32>
// upstream unrolling:
%3 = vector.multi_reduction <add>, %tile_0, %cst [1] : vector<8x16xf32> to vector<8xf32>
%4 = vector.multi_reduction <add>, %tile_1, %3 [1] : vector<8x16xf32> to vector<8xf32>
%5 = vector.multi_reduction <add>, %tile_2, %4 [1] : vector<8x16xf32> to vector<8xf32>
// new xegpu-unrolling
%3 = arith.addf %tile_0, %tile_1 : vector<8x16xf32>

[AllocToken] Propagate !alloc_token through inlined allocation wrappers (#198535)
Simple inline allocation wrappers have been preventing AllocToken
coverage for such callsites. Instead of converting such inline wrappers
to macros, we can support covering standard allocation calls in inline
allocation wrappers when inlined.
When an allocation wrapper with malloc/alloc_size attributes is inlined,
propagate its call-site !alloc_token onto return-value producing calls
exposed by inlining, so the late AllocToken pass assigns the correct
type-derived token even in default (non-extended) mode.
Propagation is restricted to calls producing the return-value(s) that
the wrapper actually returns. This keeps unrelated calls in the wrapper
body unchanged, which matters under -fsanitize-alloc-token-extended,
where any !alloc_token-carrying call is instrumented.

[Flang][bbc] Add support for -fintrinsic-module-path (#198565)
Add support for -fintrinsic-module-path to bbc. With #196558 the default
search path in the resource directory is determined by the driver, not
by the frontend (-fc1 and bbc). For tests of either frontend the tests
will need to append the search path themselves. Adding support for
`-fintrinsic-module-path` will allow using the same additional argument
for flang_fc1 and bbc tests.
Also rewriting the awkward tests that expect standard modules to fail
only because they do not contain a checksum. Maintaining this way of
testing became burdonsome because there are multiple ways of how default
modules are resolved. Fixing one breaks another.
Extracted out of #171515 to make that patch a bit smaller.

[CUF] Fix `do concurrent` PFT navigation in `cuf.kernel` lowering (#198585)
When lowering a cuf kernel directive with an explicit loop depth (e.g.
`do(2)`), the code navigated `nestedLoops-1` levels deeper in the PFT
expecting nested regular do-loops. For a `do concurrent` construct with
multiple index variables (e.g. `do concurrent(i=1:k,j=1:n)`), the PFT
represents the entire construct as a single node, so the extra
navigation stepped off into a plain statement with no nested evaluations
and triggered an assertion in `getNestedEvaluations()`.
Fix by skipping the depth navigation loop for `do concurrent`, which is
always a single flat PFT construct regardless of how many index
variables it declares.

[clang-sycl-linker] Infer target triple from input bitcode (#198036)
Previously clang-sycl-linker required `-triple=` on the command line and
errored out if it was missing. This is unnecessary requirement,
since LLVM bitcode modules already carry a target triple in
their metadata.
Resolve the triple in this order:
1. `-triple=` on the command line, if given.
2. Input bitcode's `target triple` metadata, if exists.
3. Otherwise, error out.
When inputs disagree with the resolved triple, emit an error.
Triple discovery is folded into the existing input
loop in `linkDeviceCode`, so no extra I/O pass over the bitcode files.
Update the test to drop redundant `-triple=spirv64` flags and add
coverage for inference, mismatch errors, the triple recorded in
the offload image, and the no-triple error path.

[RISCV] Fix musttail with indirect arguments by forwarding incoming pointers (#185094)
When a `musttail` call passes arguments indirectly (fp128 on RV32, i128
on RV32), the backend allocates a stack temporary and hands the callee a
pointer. The tail call deallocates the caller's frame, and the pointer
dangles.
Fix by forwarding the incoming indirect pointers instead. They point to
the caller's caller's frame, which stays valid after the tail call.
Forwarded formal parameters reuse the pointer directly; computed values
get stored into the incoming buffer first.
The pointers are saved in virtual registers (`CopyToReg`/`CopyFromReg`)
rather than SDValues. The SelectionDAG is cleared between basic blocks
and musttail calls can appear in non-entry blocks, so storing raw
SDValues across BBs is unsound (this was the bug that led to the revert
in 501417baa60f). The vreg save only fires when the function has
musttail calls; other functions see no codegen change.
Non-musttail tail calls with indirect args are still rejected.
Fixes #185089.

When the per-pid query returns nothing, fall back to the bulk

[SLP] Support ordered fadd reduction via reduction intrinsics
Add matchOrderedReduction() to recognize linearized ordered fadd chains
(both LHS- and RHS-associated) and tryToReduceOrdered() to vectorize
them using ordered reduction intrinsics (llvm.vector.reduce.fadd).
Previously, the SLP vectorizer could only vectorize ordered reductions
by keeping the original scalar chain and emitting extractelement
instructions. The new path replaces the scalar chain with a vector
ordered reduction intrinsic (where profitable), which allows the backend to lower it
more efficiently.

[flang] Do not set nuw flag on mul/add/getelementptr when lowering array_coor from a box base. (#198014)
This change is aimed to fix an issue that can be seen with the following
example, based on a test case reported in issue #197393:
subroutine s2(n1)
implicit none
integer :: n1, c(-5:-1)
associate(w => c(-1:-5:-n1))
w(n1:5:1) = 3
end associate
if (any(c /= 3)) print *, 'error', c
end subroutine s2
call s2(1)
The problem is that base pointer in a box can actually point at the end of array, which means that in order to access array elements offsets are going to be negative. That in turn means that nuw flag can't be set as
it results in poison from that GEP. Similar issue fixed with mul/add that are part of offset calculation fed into the GEP.
Fixes issue #197393.

[CIR] Hoist allocas out of deferred conditional cleanup scopes (#198680)
When a temporary alloca is created for an aggregate inside a conditional
cleanup, the alloca will also be referenced in the cleanup region of the
cleanup scope operation enclosing the conditional expression. In order
to guarantee that the alloca dominates the cleanup region, the alloca
must be hoisted out of the cleanup scope.
After CFG flattening, any allocas created at the beginning of the
cleanup scope's body region would, technically, dominate the cleanup
region, but because we can exit in the middle of the body region (via an
exception) the body region itself does not dominate the cleanup region,
and so the verifier considers any allocas within the body region as not
dominating the cleanup region.
This change looks for allocas within a deferred cleanup scope and hoists
them out of the cleanup scope before the cleanup region is populated.

Summary:
Right now we have a very heavy dependency on `flang` for a single module
file. The flang build will handle creating the actual module file, we
just need to export the symbols. This PR ports the source file from the
flang .f90 to equivalent C++. This allows us to build `flang-rt`
standalone without bringing in the entire flang infrastructure, which is
by far the heaviest build in the entire LLVM project.
I verified the symbols and values against a previous build, so they are
identical.

[mlir][emitc] Support struct and union definition (#198198)
This patch extends the `emitc.class` op to define structs and unions in
addition to classes using a new enum attribute with the values:
- class_ (class, value 0) -- default
- struct_ (struct, value 1)
- union_ (union, value 2)
Class op now takes an optional class_type, defaulting to `class`. The
attribute is printed to the assembly only when it differs from the
default, retaining current semantics, e.g.:
emitc.class @Foo { ... } // class (default, omitted)
emitc.class struct @Foo { ... } // struct
emitc.class union @Foo { ... } // union
emitc.class struct final @Foo {} // struct + final
The translator emits the class_type instead of the previously hard-coded
`class`, and for `class` types also emits `public:` inside the body,
retaining the current 'all-public classes' behavior of `emitc.class`.

[NFC][LifetimeSafety]: Track assignment history within a single CFGBlock (#196075)
## Summary
Tracking assignment history allows us to backtrack and provide more
informative error messages, helping users better understand the root
cause.
As discussed in
https://github.com/llvm/llvm-project/pull/188467#issuecomment-4359071778,
I am splitting the original #188467 into smaller parts. This PR submits
the core logic: performing a reverse search for assignment history
within a single CFG block.
A simple unit test has been added to verify the basic functionality of
the algorithm.
## Details
This function is straightforward: it iterates through each
`OriginFlowFact` in reverse order and saves the appropriate
`SrcOriginID`. Here, "appropriate" means the `Origin` contains the
target `Loan`.

everything passes with exit code 0 it is wrong not to, but make a note

[AArch64] Use ADDP tree for v16i8 to i16 bitmask extraction (#192974)
```
Before:
ext v1.16b, v0.16b, v0.16b, #8
zip1 v0.16b, v0.16b, v1.16b
addv h0, v0.8h
fmov w0, s0
After:
addp v0.16b, v0.16b, v0.16b
addp v0.16b, v0.16b, v0.16b
addp v0.16b, v0.16b, v0.16b
umov w0, v0.h[0]
```
The existing lowering in vectorToScalarBitmask for v16i8 used an
EXT+ZIP1+ADDV sequence to pack the per-lane bits into an i16. The
horizontal ADDV is expensive on some microarchitectures and forces an
early SIMD-to-GPR domain crossing.
Replace it with a three-level pairwise-add (ADDP) tree. After the AND
with the powers-of-two constant, each byte lane holds at most one set
bit within its 8-byte group, so pairwise addition cannot carry and is
equivalent to OR at every level. Three ADDPs therefore losslessly pack
the 16 per-lane bits into the low i16 of the result vector, from which
we extract the bitmask with a single UMOV.
This keeps all computation in the vector register file until the final
extract and avoids the horizontal reduction.
Partially addresses #192749. Follow-up work can extend this transform to
N=32 and N=64 by fusing across Q-registers in the first ADDP level.

[flang][OpenMP] Fix EQUIVALENCE variable privatization in OpenMP (#197726)
Fixes #197553
EQUIVALENCE aliases are lowered with `fir.ptr` addresses
(`castAliasToPointer` in ConvertVariable.cpp) to inform alias analysis.
However, `privatizeSymbol()` in Utils.cpp treated all `fir::PointerType`
values as true Fortran POINTERs, skipping the `unwrapRefType` that
computes the correct allocation type. For arrays, this caused the
privatizer to allocate pointer-sized storage instead of the full array,
resulting in stack buffer overflows at runtime.
The fix adds a `!semantics::IsPointer()` check so that only true Fortran
POINTERs preserve the `fir.ptr` wrapping. EQUIVALENCE aliases are
correctly unwrapped to their underlying type.
**Changes:**
- flang/lib/Lower/Support/Utils.cpp: Gate the `PointerType` guard on
`semantics::IsPointer` to distinguish true POINTERs from EQUIVALENCE
aliases
- flang/test/Lower/OpenMP/DelayedPrivatization/equivalence.f90: Update
existing test to match corrected output (alloc type is now `f32`, not
`fir.ptr<f32>`)
- flang/test/Lower/OpenMP/lastprivate-equivalence.f90: New test for
EQUIVALENCE'd array with lastprivate, verifying correct allocation,
deallocation, and writeback

the `directory:` field requires a non-empty directory, which isn't
guaranteed. Relax it to accept any string, including the empty string.

[lldb] Fix data race on shared global ProcessProperties callback (#197980)
ProcessProperties::ProcessProperties was installing a per-process
value-changed callback on ePropertyDisableLangRuntimeUnwindPlans. The
property was declared Global in TargetProperties.td, so
OptionValueProperties::CreateLocalCopy shared the underlying OptionValue
across every ProcessProperties. Every Process constructor therefore
wrote into the same std::function slot, racing with concurrent
constructors and silently clobbering any earlier Process's callback.

[lldb] Prioritize the MAKE_NO_DEBUG_INFO flag (#198801)
Some tests require an executable with no debug information. When
`lldb-dotest` is run with `--dwarf-version`, that flag currently takes
precedence over the debug info type specified in the test. This is
incorrect when the test explicitly expects the executable to have no
debug information.
Ensure `MAKE_NO_DEBUG_INFO` takes priority over `--dwarf-version` so
that tests requiring stripped executables behave correctly regardless of
how the test suite is invoked.

[mlir][vector] Migrate drop-lead-unit-dim to shape_cast (#196206)
Post-merge discussion on #195686 led to the conclusion that we should
change the behavior of drealeadunitdim to use shape_cast instead of
extracts and broadcasts since those are now the canonical form of such
unit-dimension striping. This commit implements that change.
The one exception is that vector contractions where the accumulator is
reduced to a scalar still use extract/broadcast. Said contract handling
also now omits any vector.transpose emissions since those are all
order-preserving and will fold into shape_casts.
The PR adds tests to ensure that scalable dimensions function correctly,
per previous PR comments. They should already have worked, but they
weren't tested.
AI: Codex 5.5 did most of the work on this one.

[OpenMP][OMPIRBuilder] Avoid querying SmallPtrSet during removal (#198690)
openmp-cli-fuse02.mlir can intermittently leave behind a dead block
after loop fusion, causing LLVM IR verification to fail.
(https://github.com/llvm/llvm-project/pull/197637#issuecomment-4497502486)
This happened because `removeUnusedBlocksFromParent` queried
`BBsToErase` while using `SmallPtrSet::remove_if` on the same set, which
made the result depend on the set's internal mutation order during
removal.
This patch tracks candidate blocks by index with `SmallBitVector`
instead of mutating and querying the same `SmallPtrSet`. This also
preserves the original `BBs` order when collecting the final dead
blocks.

The original PR was created with assistance from Copilot. The later
analysis and fix were revised based on reviewer feedback.

[llvm][OpenMP] Add option to disable default max threads adjustment (#198719)
This commit adds the option
`-openmp-ir-builder-use-default-max-thread=<boolean-value>` to
enable or disable the use of a default max threads in OpenMPIRBuilder
when no max threads constant is provided. The option is enabled by
default, thus maintaining the same behavior as it is currently.
This flag is useful to avoid limiting the number of threads that an
OpenMP target region can run with when no `thread_limit` or
`num_threads` (in a nested parallel region) are specified. This flag may
be used when recording a kernel to allow replaying it later with a
higher number of threads (e.g., reaching the maximum thread limit
supported by the device).

[flang][PPC] Improve vector type names in expression diagnostics (NFC) (#197821)
Improve Flang semantic diagnostics for vector types by printing vector
type spellings in Fortran syntax instead of internal builtin-derived
type names.
Use `DerivedTypeSpec::VectorTypeAsFortran()` when producing vector
operand type names in `ArgumentAnalyzer::TypeAsFortran()`, instead of
relying on the generic type formatting path.
This updates diagnostics to print vector types as Fortran source-like
spellings, such as:
- `vector(integer(4))`
- `vector(real(4))`
while preserving the existing formatting for non-vector derived types.

[libc++] Require the exact assignment expression to be trivial in __uninitialized_allocator_copy_impl (#196648)
Fixes https://github.com/llvm/llvm-project/issues/196645
`__uninitialized_allocator_copy_impl` has an optimization that replaces
`allocator_traits::construct` with `std::copy` for raw pointer ranges
when the element type is trivially copy constructible and trivially copy
assignable.
The copy-assignment trait only checks whether assignment from `const T&`
is trivial. That is weaker than the expression used by `std::copy`,
which evaluates `*out = *in`. If overload resolution selects a different
non-trivial assignment operator for that expression, `std::copy` can
call that operator on uninitialized storage.
Check `is_trivially_assignable<_Out&, _In&>` instead. This matches the
assignment expression used by `std::copy`, preserves the optimized path
when that assignment is actually trivial, and avoids making non-const
raw pointer callers select the generic `allocator_traits::construct`
overload due to a qualification conversion.
Add a vector copy-constructor regression test with a type whose
defaulted copy assignment is trivial but whose templated assignment
operator is selected for non-const lvalue sources.

[Offload] Make profiling support opt-in on events (#198810)
Summary:
Profiling requires getting time stamp information, which required
actually materializing barriers on the event. This caused performance
regressions in some OpenMP applications. Instead, we want to make this
opt in. This just adds a new argument to `olCreateEvent` which takes
some flags. Right now this is just none and profiling. Pretty mechanical
beyond that. Should revert this to the old behavior for OpenMP.

[VPlan] Add type in VPRecipeValue, migrate first set of recipes. (NFC) (#195485)
This patch adds a new Type field to hold the scalar type for the
VPRecipeValue. It starts the migration of an initial set of recipes to
set the scalar type and use it directly in VPTypeAnalysis, removing
special handling for those types.
Eventually, VPTypeAnalysis can be retired when the migration is
complete, hopefully eliminating the need for type related caching, which
can lead to subtle invalidation errors.
To help the transition, a temporary getScalarTypeOrInfer has been added,
which returns the scalar type set in the VPValue for already migrated
recipes or falls back o type inferrence otherwise.
VPlanVerifier has been extended verify the set scalar type where
possible.
Tracking the type directly means a few places that change the type will
need to be updated to create a new replacement recipe with correct
types.

[CIR] Fix bugs with array new in a ternary expression (#198869)
While attempting to compile Clang with CIR enabled, we ran into a
problem with the cleanup handling for array new inside of a ternary
operation. The reduced test case ended up showing different failure
modes with and without exceptions enabled, but it failed in both cases.
With exceptions enabled, we were failing to spill the value to be
returned and reload it outside of the cleanup scope. With exceptions
disabled, we were pushing an effectively empty entry on the EH stack and
later asserting when trying to pop it.
This change fixes the spill and reload problem by inserting a
RunCleanupsScope RAII object around the ternary branch generation code
with a call to forceCleanups to generate the spill and reload.
The assertion failure is fixed by replacing the assert call with code to
safely handle the condition of having an empty cleanup on the EH stack.
We should probably modify the code that pushes EH-only cleanups to avoid
doing so when exceptions are disabled, but that's a more extensive
change and having the new handler as a safe backstop seems like a good
idea.
Manual inspection revealed a second location where we're generating a
cir.ternary operation that had the same spill and reload problem
described above, so that is fixed here too.

ScriptedProcess, BreakpointResolverScripted, ScriptedFrameProvider) pass
their existing ScriptedMetadata directly, removing the need to re-bundle
class_name and args at every call site.
ScriptedBreakpoint, ScriptedFrameProvider and ScriptedProcess no longer
carry a redundant `args_sp` parameter; their callers fold those args
into the metadata, and the Python overrides reconstruct a
StructuredDataImpl from the metadata's args dict for the dispatched
call.
ScriptedInterface gains an `m_scripted_metadata` member and a
`GetScriptedMetadata()` accessor; ScriptedPythonInterface populates it
when CreatePluginObject is invoked so subclasses can later report which
script class is in play.
Hook/StopHook/ThreadPlan public interfaces keep their existing `args_sp`
parameter for now; subsequent commits consolidate that.

[clangd] Fix crash when server shuts down with in-flight rename or tweak (#198019)
Fixes #196225.
Root cause: When clangd shuts down, `ClangdLSPServer`'s destructor calls
`Server.reset()` to destroy the `ClangdServer` object. `ClangdServer`
then destroys the work scheduler, which blocks and waits for in-flight
tasks to finish. If a rename task is in flight, the callback will try to
access the now-reset `ClangdLSPServer::Server` in
https://github.com/llvm/llvm-project/blob/4f9a7d09f4760ac9c5745e8bb829366d29ff9687/clang-tools-extra/clangd/ClangdLSPServer.cpp#L916-L917
The same issue occurs with `onCommandApplyTweak`, as its callback also
accesses `ClangdLSPServer::Server`:
https://github.com/llvm/llvm-project/blob/4f9a7d09f4760ac9c5745e8bb829366d29ff9687/clang-tools-extra/clangd/ClangdLSPServer.cpp#L828-L829
A reproducer has been added to #196225.
This PR fixes these issues by capturing a reference to `ClangdServer`
and using it in the callbacks instead of the `ClangdLSPServer::Server`
optional. The reference is guaranteed to remain valid because the work
scheduler syncs while the server is being destroyed.
Includes a unit test that verifies the fix for `rename`. The test for
`applyTweak` was omitted because the mocked LSP client would trigger an
`ADD_FAILURE()` ("Unexpected server->client call") when intercepting the
outgoing `workspace/applyEdit` request. While this could be handled with
`EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS`, it would make the test flaky
because the task could occasionally finish before the server shuts down.

This file uses `EFIAPI`, but it's not included. It looks like
compilation currently succeeds because `EFI_SYSTEM_TABLE.h` is the only

We will be adding Bazel rules for this file, and Bazel typically
requires all headers to be compilable on their own. This build error is
theoretically reproducable by running cmake build with
`-DCMAKE_VERIFY_INTERFACE_HEADER_SETS` if we had the appropriate

[RISCV] NFC: Use the new "let append" TableGen feature to reduce duplication (#198761)
llvm#182382 introduced a language extension to accumulate field values:
“append” concatenates the new value after the current value, whilst
"prepend" concatenates before the existing value. This change uses that
feature to eliminate repetition in the definition of some of the
compressed instructions.
For example, line 267 of RISCVIntrInfoC.td establishes a scope for “`let
Predicates = [HasStdExtZca] in {`”; this scope ends on line 515.
Meanwhile, line 454 wants to add the `IsRV64` predicate for a single
instruction but was forced to duplicate the previous condition as well:
“`let Predicates = [HasStdExtZca, IsRV64] in`”. That’s no longer
necessary since the addition can now be explicit: “`let append
Predicates = [IsRV64] in `”
I‘ve verified that this change has no effect on the TableGen output.
It seems quite likely that this same change could be made in some of the
other RISC-V TableGen source files…

The Windows API can deliver `LOAD_DLL_DEBUG_EVENT` with `hFile` set to

inside Windows Server Core containers for system DLLs like
`kernel32.dll`, `KernelBase.dll` and `ucrtbase.dll`. This is the issue

`DebuggerThread::HandleLoadDllEvent` previously dropped any such event.
This patch improves the module path resolution with the 2 following

- `GetFileNameByLoadAddress`: resolve the module path given its base
load address.
- `GetFileNameFromImageNameField`: resolve the module path given the
`LOAD_DLL_DEBUG_INFO::lpImageName` field.

[Clang] Disallow `break`/`continue` in loop conditions (#198436)
tl;dr: This makes e.g. `while (({ break; 1; })) {}` ill-formed.
GCC used to allow this a long time ago (< GCC 9 I believe), but
eventually removed support for it; we originally allowed this both for
GCC compatibility and because there was actual code in the wild using it
(see Richard’s comment here for more background:
https://github.com/llvm/llvm-project/pull/152606#issuecomment-3166130973).
Note that this _is_ still allowed inside another loop, e.g. this
```c++
for (;;) {
while (({ break; true; })) {}
}
```
is well-formed; the `break` here will break out of the `for` loop.
Removing support for this gets rid of quite a bit of code and has a few
more benefits:
1. Currently, GCC and Clang _disagree_ on the meaning of this construct
in nested loops: in the code snippet above, Clang breaks out of the
`while` loop, whereas GCC breaks out of the `for` loop; this patch
changes Clang to align with GCC here. As a result, we can also remove
code that emits a warning for such cases.
2. It frees up a bit in `ScopeFlags::Flags`, which is a good thing
because I need one for expansion statements, and we’re out of bits. This
is because we currently use a bit as a hack to disallow `continue`
inside the declaration of the condition variable (because we’d
`continue` to the condition before initialising the variable); this bit
becomes obsolete with this patch because `continue` is now disallowed
entirely within the condition (if there is no outer loop).
Without this change, I’d have to refactor `Flags` to be a 64-bit
integer, which would also entail updating every place where we use an
`unsigned` to store scope flags.
There is another change that I needed to make here: we currently
suppress `-Wcomma` (which warns about comma operators, because in most
contexts, you probably didn’t mean to use one) in some places, including
the third part of a C-style `for` loop. This is implemented by checking
if we’re in a `BreakScope | ContinueScope`, but those scope flags are
now only set when parsing the loop body. Instead, we now check for
`ControlScope`. This requires us to also set that flag in C90 mode, but
that seems to be harmless as the only use of `ControlScope` I was able
to find is in C++ code paths, where that bit was already set anyway.
When we introduced named loops for C2y, we purposefully didn’t support
labeled break/continue in the condition, so there’s nothing to be done
there (we already have tests for this too).

[CIR][CIRGen] Cast stack allocas to the language-visible address space (#196868)
This patch aims to improve parity with OG codegen on targets with
non-flat alloca address space. I observed this after getting some
crashes while compiling PolybenchGpu for HIP (amdgpu). This work had
previously been merged in the incubator, most notably:
https://github.com/llvm/clangir/pull/2090,
https://github.com/llvm/clangir/pull/2088.
CIR currently returns the raw `cir.alloca` address from temporary/local
alloca creation. On AMDGPU, stack allocas live in private addrspace(5),
but ordinary C/C++/HIP auto variables are still used through the
language-visible generic/flat address space.
OG CodeGen handles this by creating the alloca in the target stack
address space and immediately casting it to the language-visible address
space when those differ. For example:
```llvm
%fmt = alloca [6 x i8], align 1, addrspace(5)
%tmp = alloca ptr, align 8, addrspace(5)
%fmt.ascast = addrspacecast ptr addrspace(5) %fmt to ptr
%tmp.ascast = addrspacecast ptr addrspace(5) %tmp to ptr
%arraydecay = getelementptr inbounds [6 x i8], ptr %fmt.ascast, i64 0, i64 0
store ptr %arraydecay, ptr %tmp.ascast, align 8
```
I've also added a helper to recover the underlying alloca through casts
for callers that need to annotate the original cir.alloca, and preserves
source pointer address spaces when creating pointer bitcasts.

[libc] Update prctl() declaration to use variadic arguments. (#198654)
prctl declaration should typically use variadic arguments (e.g. see
https://man7.org/linux/man-pages/man2/prctl.2.html), as the types /
quantity of subsequent arguments depends on the `option`. We can't
depend on all `<prctl.h>` users to explicitly cast arguments to
`unsigned long` and passing all 5 of them every time.
* Don't add any option-specific logic, and just consume `arg2`-`arg5`
from variadic arguments and pass them to syscall implementation as-is,
assuming that they won't be used by the kernel if they are not needed,
and consuming these arguments won't lead to crashes.
* Updated the test to use `prctl` variants with less than 5 explicit
arguments (for PR_SET_NAME and PR_GET_NAME).

[NVPTX] Add commutativity to SETP instructions to enable MachineCSE of inverted predicates (#191890)
Inverted predicates can be used freely in PTX. If we can invert a
predicate and CSE the generating instruction we can save calculating the
inverse.
Teach the NVPTX `commuteInstructionImpl` that SETP instructions can be
inverted to allow CSEing with previous SETP that match the inverted
form. This also inverts the branch users of the predicate to maintain
correctness.
Currently only allow the SETP inversion if all users are branches.
Future work can extend this to `sel` and `not` instructions.
Depends on #191889.

This change adds support for properly defining and obtaining

thread-id (which satisfies necessary restrictions of having total order,
being hashable and formattable) as `pthread_id_np_t` type and uses
`pthread_getthreadid_np` and `pthread_getunique_np` functions to obtain
it (added in

discussions in https://github.com/llvm/llvm-project/pull/195139 and
https://github.com/llvm/llvm-project/pull/195202).
We also let `_LIBCPP_NULL_THREAD` macro use a more portable
`PTHREAD_NULL` (defined in the latest POSIX) when this macro is
available, so that it would work as expected for opaque `pthread_t`
implementations, where default constructor might not necessarily
zero-initialize all the members.
This is the last remaining change to allow building libc++ against
llvm-libc with threads enabled (test-suite results TBD).

[LLDB] Add a progress event to xcrun invocations (#198931)
LLDB invokes xcrun to find SDKs on disk. This is usually very fast, but
sometimes (after an Xcode update, or when the searched SDK does not
exist) it can take very long (10s or more). The progress event provides
user feedback to explain the hang.

[Github] Add timeouts to libc tests (#198934)
None of these jobs do not take anywhere close to the six hour timeout
that Github uses by default. Set timeouts that are 2-3x the typical job
runtime so that if there is a test/build step that hangs indefinitely,
the job times out in a reasonable amount of time and does not hold any
resources that could be used elsewhere.
This should not impact any jobs that do not hang, will not change the
result of jobs that do hang, and means we can more effectively deal with
cases like today where tests were hanging, from a resource perspective.
This is also standard in some other workflows like the main premerge
workflow definition.

[AggressiveInstCombine] Recognizing tail truncation in the popcount pattern (#198658)
We're currently able to recognize the following popcount pattern
```
int popcnt(unsigned x) {
x = x - ((x >> 1) & 0x55555555);
x = x - 3*((x >> 2) & 0x33333333);
x = (x + (x >> 4)) & 0x0F0F0F0F;
x = x + (x >> 8);
x = x + (x >> 16);
return x & 0x0000003F;
}
```
but if a truncation follows right after the last AND instruction:
```
int16_t popcnt(unsigned x) {
x = x - ((x >> 1) & 0x55555555);
x = x - 3*((x >> 2) & 0x33333333);
x = (x + (x >> 4)) & 0x0F0F0F0F;
x = x + (x >> 8);
x = x + (x >> 16);
return int16_t(x & 0x0000003F);
}
```
since InstCombine canonicalizes `(trunc (and y, C))` into `(and
trunc(y), C')`, we might loose the opportunity to turn the above snippet
into `(trunc (popcount x))` as there is a `trunc` interrupting the
pattern matching.
This patch fixes this issue by considering this extra `trunc` during
pattern matching, and appending it in the final popcount result, if
there is any.

[lldb] Make TypeSystem::m_sym_file atomic to fix data race (#198923)
SymbolFileCommon::GetTypeSystemForLanguage unconditionally writes this
pointer with `ts->SetSymbolFile(this)` on every lookup, which races with
concurrent reads from other threads.
The race is benign in practice: there is exactly one SymbolFile per
Module, so every writer stores the same pointer, but it is still
undefined behavior under the C++ memory model.
Make the field std::atomic<SymbolFile *> and turn SetSymbolFile into a
compare-exchange that asserts a TypeSystem is never rebound to a
different SymbolFile, documenting the invariant that lets us get away
with this.
The alternative is to have the SymbolFile pointer passed in through the
constructor, but that would require updating a bunch of call sites,
including various plugin interfaces.
Found by ThreadSanitizer as part of #197792.

[AMDGPU] Rewrite `-march` to `-mcpu` in the AMDGPU Toolchain (#198877)
Summary:
Pretty much every target uses either `-mcpu` or `-march` consistently.
AMDGPU has been accidentally using both for a while, mostly from some
fallout with the OpenMP Toolchain. This is too deep to pull out without
potentially disrupting users, but I want to at least contain it by
canonicalizing `-march` to `-mcpu` in the driver. This means we don't
need to bother checking both like every other target does.

[flang-rt] Silence -Wfenv-access in the runtime fenv wrappers (part 1) (#198692)
Upstream clang's commit 5f2bedca, PR #187860, enabled a warning that
fires whenever code calls a `<fenv.h>` / `<cfenv>` primitive without
enabling proper FP exception behavior. This caused warnings in compiling
flang-rt, which in turn caused certain buildsbots to fail with
`-Werror`.
This change enables FP trap behavior for parts of flang-rt that are
known to require it. The other parts will be addressed by a future
change.

extend the existing isPExtPackedType branch in lowerSELECT to bitcast to
an integer of matching width: single-GPR types select on XLenVT
directly, while RV32 double-wide types select on i64 which
type-legalizes to two scalar selects on the i32 halves.
v2i32 is left to natural type-legalization since it splits cleanly into
two scalar i32 selects without a Custom hook.

[LoopInterchange] Always create a new latch when interchanging (#194574)
In the transformation phase of loop-interchange, when the inner loop to
be interchanged is the innermost one, a new latch BB is created and
several instructions are moved from the original BB to the new one to
generate valid IR. I'm not sure why this process was performed only when
the target loop is the innermost loop, but as demonstrated in #163954,
this process is also necessary when interchanging non‑innermost loops,
e.g., when a reduction exists and the reduction operation is located in
the latch BB of the inner loop.
This patch removes the conditional branch and always creates a new latch
during the transformation.
Fix #163954

[LoopInterchange] Make the instorder profitability check GEP-independent (#181991)
The heuristic function `instorder` assumes that the structure of GEPs
reflect the original memory access patterns, which is not always true.
Moreover, recent trends in LLVM are moving in a direction where such
patterns are no longer preserved. If the migration from GEP to ptrtoadd
is completed, this heuristic will no longer make sense.
To achieve what this heuristic is trying to do, we should examine the
SCEV of the pointer operands of loads/stores, rather than relying on
GEPs. This patch replaces the GEP‑dependent logic with an SCEV‑based
analysis. Instead of relying on the operand order in GEPs, the
SCEV‑based approach walks through the SCEV expression, identifies the
step recurrences of the relevant loops, and compares them. This allows
us to perform what `instorder` intends to do without relying on how
memory access patterns are represented in the IR.

[LV] Convert gather loads with constant stride into strided loads (#147297)
This patch detects non-consecutive load accesses (i.e. gather) with a
constant stride, such as:
```
void stride(int* a, int *b, int n) {
for (int i = 0; i < n; i++)
a[i * 5] = b[i * 5] + i;
}
```
and converts them into strided loads when legal and profitable, using
experimental_vp_strided_load.
The new VPlan transformation, convertToStridedAccesses, hoists the
functionality of RISCVGatherScatterLowering into the vectorizer,
enabling a more precise cost estimation during vectorization.
Additionally, by leveraging SCEV for stride analysis, the vectorizer can
potentially detect more opportunities to optimize gathers into strided
loads.
This enables more efficient code generation for targets like RISC-V that
support strided loads natively.

[LoopInterchange] Bail out when memory instruction ratio is high (#192954)
Currently, to save compile-time, LoopInterchange limits the number of
memory instructions and bails out early if it exceeds a threshold.
However, the dependence analysis phase in LoopInterchange has `O(N^2)`
complexity, where `N` is the number of memory instructions. This means
that even a small number of memory instructions can have a
non‑negligible impact on compile-time. In fact, I found such a case
(about +5% compile‑time regression), which the most instructions in the
loop are stores.
This patch replaces the heuristic which determines whether we should
continue the analysis or bail out to save compile time. The idea is that
if the ratio of the squared number of memory instructions to the total
number of instructions is small, LoopInterchange is allowed to continue
its analysis. The existing option `-loop-interchange-max-meminstr-count`
is removed.
Compile-time improvement:

[clang] Complete fields in __builtin_offsetof designators (#195126)
Code completion was a no-op inside `__builtin_offsetof`: a cursor at `
__builtin_offsetof(T, ^)` or `__builtin_offsetof(T, a.^)` fell through
to ordinary-name completion instead of suggesting fields. Route the
code_completion token to a new SemaCodeCompletion entry point that walks
the designator path so far, resolves the subobject's type, and
enumerates its members. Methods are filtered out, inherited fields are
included, indirect fields from anonymous unions and structs are peeled,
and `using Base::field` resolves through its UsingShadowDecl. A
code_completion token past a complete component (right after `]` or at
the end of the chain) is dropped rather than offering fields the user
can't paste without first typing `.`.
The offsetof and designated-initializer type walkers are folded into one
helper parameterized by a field-lookup callback, which incidentally
fixes reference-field and indirect-field traversal in
designated-initializer completion too.
Tests: lit cases in offsetof.cpp covering empty/dot/array/inheritance/
reference/anonymous/using-shadow/macro forms, extended desig-init.cpp
walker cases, and a clangd unit test exercising the IDE path.

[CostModel] Move the arbitrary load latency into getMemoryOpCost (#198790)
Currently TargetTransformInfoImpl returns an arbitrary cost of 4 for the
latency of loads in getInstructionCost. This means even if a target
correctly reports the latency for loads in getMemoryOpCost we still get
this arbitrary cost in getInstructionCost. It also means the latency
cost is inconsistent depending on whether you go through
getInstructionCost or getMemoryOpCost.
Solve this by moving the current arbitrary cost into getMemoryOpCost.
This has the side-effect of affecting the cost of masked loads if they
aren't handled by the target, as in BasicTTIImpl the cost for these is
calculated using getMemoryOpCost. This should mean the cost is more
accurate though, and likely won't have any effect as in any
transformation that could introduce masked loads (e.g. vectorization)
the current cost is probably high enough that it's already not worth
using.

`func3` and `func4` are

[Proof of correctness](https://alive2.llvm.org/ce/z/ZthC9m)
```c++
#include <stdint.h>
uint64_t func3(int32_t a, int32_t b) {

}
uint64_t func4(int32_t a, int32_t b) {
return (b < a ? 0 : (uint32_t)(b - a));
}
```
In x86-64, it would make shorter code by zero-extending instead of
sign-extending b - a.
My PR fixes this by handling all patterns below:
`(X < Y) ? 0 : (X - Y)`
`(X > Y) ? 0 : (Y - X)`
`(X < Y) ? (Y - X) : 0`

[LoopInterchange] Disable LoopCacheAnalysis-based heuristic by default (#193478)
LoopInterchange has three types of heuristics for profitability
decisions: `cache`, `instorder`, and `vectorize`. Currently, the
profitability check invokes these heuristics in this order. The
heuristic corresponding to `cache` is based on LoopCacheAnalysis.
However, LoopCacheAnalysis applies several aggressive heuristics, which
can sometimes lead to undesirable decisions. In contrast, the heuristic
corresponding to `instorder` is relatively simpler than `cache`, but its
behavior is clear and it is likely sufficient for practical cases.
In light of the default enablement, I believe it is better to use a
simpler, easier‑to‑reason‑about, and more stable heuristic rather than
an aggressive but complex one. Therefore, this patch disables the
LoopCacheAnalysis‑based profitability check by default.

[Flang][OpenMP][NFC] Remove Fortran Evaluate Depedancy from Support (#198742)
Following #197442, FortranEvaluate was implicitly included in
OpenMP-utils.h which should be avoided to ensure front-end data
structures in the Optimizers can stop and restart pure MLIR source
without any side-data structures.
To ensure this is done, EntryBlockArgs has been stripped back to only
track vars, objects are now tracked within ObjectEntryBlockArgs in
Lowering as this is a more appropriate place for this information, and
the existing symbol tracking in EntryBlockArgsEntry was only used here.
This ensures FortranEvaluate is not needed within the Optimizers, and
objects can still be maintained when lowering. This enables better
referencing in Reduction Clauses, where previously context was being
lost for expressions such as ArrayElements.

[RISCV] Ensure AVL dominates True in vmerge peephole (#199008)
When folding vmerge into its true operand, if vmerge has an AVL defined
by a register and true has VLMAX, then the minimum AVL will be the
register. In this case it's not guaranteed to dominate true, so we need
to potentially sink true so it does.
This teaches ensureDominates to check multiple definitions at the same
time, since we want the sinking to be atomic.
Fixes #198733

all such operations.

This patch implements

been accepted into C++26 at the Croydon meeting through [CWG Motion
3](https://github.com/cplusplus/draft/issues/8824).
This change has not been designated a defect report. However, there was
recently some discussion about this designation and GCC implements it as
DR. Therefore, this is treated as DR regardless.

[PowerPC] set libcall lowering for fp setcc ops on SPE boards (#153238)
SPE fp comparison instructions don't comply with IEEE-754. They treat
special values like NaN and Inf as normalized numbers, which leads to
incorrect results. For example, when comparing NaN with a normal, the
result can be true, even though the standard requires comparisons with
NaN to be false.
This patch fixes the issue by lowering these operations to libcalls. SPE
comparison instructions can still be used when fast-math flag is
enabled.

clang: Add BoundArch/OffloadKind argument to getSupportedSanitizers (#196503)
Currently the AMDGPU HIP and OpenMP toolchains falsely report
all host sanitizers are supported, and then go out of their way
to skip forwarding those to the device compiles. Add an offloading
kind argument so that in the future this can be handled in one
place in the base toolchain.

[CIR] Fix problem with multiple references to an alloca in a cleanup (#198928)
A recent change to hoist allocas out of a deferred cleanup scope had a
bug wherein if multiple entries in the deferred cleanup stack referenced
the same alloca, the second attempt to see if it needed to be hoisted
would assert in the MLIR region code. This was happening because when we
hoist the alloca, we hoist it to a block that is still under
construction. On the second encounter when we're walking its parent
chain to see if it is contained within the cleanup scope we're
processing, our call to get the parent region of the block containing
the alloca would assert because the alloca is in an unlinked block (it
gets added to a region after we're done constructing it).
To fix this problem, I changed the way we're checking for the alloca
being nested within the cleanup scope, using a more robust
implementation that will tolerate encountering unlinked operations.

clang: Refactor handling of offload sanitizer arguments (#196737)
Previously the AMDGPU toolchains hackily handled -fsanitize arguments.
They would lie and report that all host side sanitizers are available,
then TranslateArgs would filter out the device side cases that do not
work, providing diagnostics for the skipped cases. Move that logic
into the base sanitizer argument parsing.
This makes the produced diagnostics more consistent. Previously we
would get repeated warnings when a sanitizer is fully unsupported
by amdgpu, which should now be once for the toolchain. These could
be further improved; we're printing the specific field of -fsanitize
in more cases where it could be skipped. In other cases we have the
opposite problem, where we aren't reporting the exact sanitizer
from the -f flag in the case that depends on a subtarget feature.
This will help fix other broken target specific flag forwarding bugs
in the future.

It used to need to get the whole bb predecessor count and then check

check against 1, 2 or 3. By using its already existing basic block
predecessor count function, these attributes can be counted much faster.
Now it doesn't need to go through the whole list. The moment it gets to
the 3rd element, no matter how many predecessors there might be, we have
our answer for the metrics

[clang] Allow clang only write module/pch when output is different (#198881)
Add an parameter to the output file creation function in clang to allow
it to configure output backend to only write output if the file is
different from the file on the disk. This is useful in a legacy build
system where the incremental build state is tracked by timestamp. For
example, producing the same clang module in the build will not update
the timestamp, thus downstream jobs do not need to be re-run.
The default value is not change so NFI is expected. This is only to
allow clients need such behavior to enable when needed.

[AMDGPU] Skip bridge copies for grouped MFMA instructions (#198555)
When the MFMA-form rewrite moves a chain of matrix ops from VGPR to AGPR
form, the bridges between ops in the chain don't exist post-rewrite,
instead they all live in AGPR-form together. The cost model was counting
those phantom bridges and rejecting rewrites that were actually
profitable.
Treat the candidate set as a group. Edges inside the group need no
bridge. Skip candidates whose results escape to non-matrix users.

rendered 'moot' by the former patch.
After looking into it further, I believe that the former is the
'correct' patch.
THIS patch is a partial revert of my patch, leaving the lambda (as I
think it is a good 'readability' improvement), plus leaving/updating
the test.

`sanitize_hwaddress`, `sanitize_mem_tag`). This prevents the Attributor
from inferring "amdgpu-agpr-alloc"="0" for sanitized functions or their
callers, letting the register allocator conservatively reserve AGPR
capacity.
This patch should prevent kernel to exceeds the hardware register budget
on gfx90a where VPGR and AGPR share the same physical register file.

[PowerPC][NFC] Change arguments of PPCPostRAExpPseudo/PseudoXFormMemOp (#198861)
The assembler string of the pseudo is almost always a # followed by the
name of the pseudo. A good part of the pseudos does not have a pattern.
Changing the order of arguments asmstr and pattern in PPCPostRAExpPseudo
and PseudoXFormMemOp, and assigning default values, reduces repetitions.

[flang][AddAliasTags] Fix segfault when type contains `fir.boxproc` (#198997)
`fir.boxproc` currently has no LLVM representation (its converter
returns `std::nullopt`). When `AddAliasTags` called
`getTypeSizeAndAlignment` on a type containing `fir.boxproc` (e.g. a
sequence of a derived type with procedure pointer components),
`convertRecordType` and `convertSequenceType` would crash trying to
mlir::cast a null type.
For any type that might recursively contain a non-convertible type
(`fir.boxproc` in this case), `TypeConverter` would now propagate an
empty optional `mlir::Type` and emit a debug warning that conversion
failed. This helps us avoid seg faulting expecting that the type or some
part of it were converted correctly.

enabling modular printf support. This is safe for older clang and other

[Driver][MSVC] Use LLD if DWARF is requested (#198600)
Clang can emit DWARF on Windows if requested with `-gdwarf` (or
`-gdwarf-N`). The generated object files will then have the `.debug_*`
sections. These section names are all larger than eight bytes. This
creates an issue in the final executable. PE/COFF executables don't
allow section names longer than eight characters. From the
[docs](https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#section-table-section-headers):
> **Name**: An 8-byte, null-padded UTF-8 encoded string. If the string
is exactly 8 characters long, there is no terminating null. For longer
names, this field contains a slash (/) that is followed by an ASCII
representation of a decimal number that is an offset into the string
table. Executable images do not use a string table and do not support
section names longer than 8 characters.
MSVC's linker follows this and will truncate section names in
executables. So a `.debug_info` would become `.debug_i`. LLD on the
other hand does allow these long section names (with a warning). This
makes DWARF work on MinGW.
The MSVC toolchain will use the MSVC linker by default (unless
`CLANG_DEFAULT_LINKER` specifies a different one). This will truncate
the section names. So if one would want to use DWARF, they'd also need
to link with LLD.
This PR changes the default linker to LLD if DWARF is requested.
Otherwise, the old default will be used.

of the bundle, vectorizeTree later sets the IRBuilder insertion point

[Clang][AST] Fix ExplicitInstantiationDecl accessors for variable templates with tag types (#197856)
Several `ExplicitInstantiationDecl` accessors assumed that
`TypeSourceInfo` always encodes a class entity, but for variable
templates the `TypeSourceInfo` holds the *declared type* (e.g. `Plain`,
`Color`, `Wrap<int>`). When that declared type happened to be a
`TagType` or `TemplateSpecializationType`, the accessors would
misinterpret it:
- `getTypeAsWritten()` returned `nullptr` → crash in `DeclPrinter`
- `getQualifierLoc()` leaked the type's qualifier into the variable name
- `getTagKWLoc()` returned the type's elaborated keyword
- `getNumTemplateArgs` / angle-loc getters extracted from the type
instead of the variable's template arguments
Add a private `getClassTypeLoc()` helper that returns the entity
`TypeLoc` only for class-like instantiations
(`isa<RecordDecl>(getSpecialization())`), and guard all `TypeSourceInfo`
fallback paths with it. For non-class entities the accessors now
correctly skip the `TypeSourceInfo` and return defaults or read from
trailing objects.
Also fix stale template argument source locations for variable
templates: when an explicit instantiation definition follows a prior
declaration, `VarTemplateSpecializationDecl::getTemplateArgsAsWritten()`
returns the first declaration's locations. Construct fresh
`ASTTemplateArgumentListInfo` from the current declarator instead.

[flang] Canonicalize sliced array access by fir.array_coor. (#197845)
This patch adds a canonicalization pattern for pulling rank-reducing
slices into `fir.array_coor`. This is helpful to preserve the original
rank of the array in `fir.array_coor`, which then helps representing
slice accesses in memref dialect as accesses to the original array.
This way, further conversion to affine dialect has benefits of
exposing the math applied to indices of all array dimensions.
For example, if a non-scalar slice depends on a loop IV, pulling
this into the original array access allows building access maps
enabling affine dependency analysis.
I considered the following three models for the addressing used
in `fir.array_coor` with rank reducing slices:
1) Mixed model:
- Encoding
* Scalar-sliced dims: index is slice_lb
* Non-scalar dims: index is section-style (1-based)
- Pros
* Minimal canonicalization math
* Keeps scalar selection explicit in the index list
- Cons
* Semantics are mixed in one array_coor
* Harder to reason about/debug
* Requires special-case logic in later lowering (FIRToMemRef / CodeGen)
to interpret non-scalar dims differently from scalar dims
2) Uniform section-style model (all 1-based):
- Encoding
* Scalar-sliced dims: index is 1
* Non-scalar dims: index is section-style (1-based)
* Scalar selection recovered only from slice_lb
- Pros
* Conceptually clean and consistent (single index convention)
* Easier mental model
- Cons
* Needs coordinated changes in both lowerings
* Lowerings must always reconstruct scalar selected coordinates
from slice metadata
* Higher migration risk unless all paths are updated together
3) CodeGen-compatible coordinate-space model (the implemented one):
- Encoding
* Scalar-sliced dims: index is slice_lb
* Non-scalar dims: index converted to coordinate-space (lb + idx - 1)
- Pros
* No behavioral changes needed in CodeGen logic
* Aligns canonicalized IR with existing coordinate-space assumptions
* Avoids extra CodeGen compatibility branches
- Cons
* Canonicalization is more complex (must synthesize index transforms)
* FIRToMemRef still needs alignment for full-rank vs reduced-rank
index consumption
* Slightly less "visually uniform" than all-1-based

[AIX][clang][compiler_rt] rename libatomic archive to libclang_rt (#197485)
This PR implements the following on AIX to avoid conflicts between LLVM
libatomic and the GNU libatomic in the AIX toolbox as they share the
same library name:
- Updates the clang driver to use `-lcompiler_rt` instead of `-latomic`
- Renames the compiler-rt archive from `libatomic.a` to
`libcompiler_rt.a`
Only the archive and not the shared object (`libatomic.so.1`) is renamed
because renaming one component is enough to distinguish between the LLVM
and GNU libatomic libraries. This also allows us to add additional
shared objects to the `libcompiler_rt.a` archive in the future if
needed.

[lldb][CMake] Enforce lldbUtility and lldbHost layering invariants (#198952)
lldbUtility cannot depend on any other lldb library, and lldbHost can
only depend on lldbUtility. Breaking those invariants is an easy mistake
to make and has happened repeatedly: most recently in #198931.
Because LLDB statically links its libraries on macOS, a stray LINK_LIBS
entry, or a stray cross-library #include without a matching CMake
dependency, both succeed at link time and only surface much later as a
layering bug.
Add two configure-time checks in `add_lldb_library` so the build fails
fast when these invariants are broken:
1. A new `ALLOWED_INTERNAL_DEPENDENCIES <list>` parameter allowlists
which `^lldb`-prefixed `LINK_LIBS` entries a target may depend on. The
existing `NO_INTERNAL_DEPENDENCIES` flag is the empty-allowlist case and
continues to work.
2. Whenever either of those is set, also scan the target's sources and
public headers for `#include "lldb/<Library>/..."` directives outside
the allowlist, and FATAL_ERROR with the offending file and line. This
catches the macOS static-linking case where a missing CMake dependency
silently resolves at link time.
Apply the new parameter to lldbHost (allowing only lldbUtility plus the
Darwin Objective-C++ shim lldbHostMacOSXObjCXX) and to that shim itself.
lldbUtility already used `NO_INTERNAL_DEPENDENCIES` and now picks up the
header scan automatically.
`lldb/Host/windows/windows.h` is special-cased in the scan: it is a
system-header wrapper used tree-wide and carries no real dependency.
Drop two unused `lldb/Target/*` includes from `Utility/FileSpecList.cpp`
that the scan would otherwise flag.

[flang] Implement lowering for BOZ literal arguments in BGE, BLE, BGT, BLT (#191874)
BGE/BGT/BLE/BLT allow one or both arguments to be a BOZ literal
constant. Unlike other intrinsics that accept BOZ arguments, these do
not convert the BOZ to a typed value during semantic analysis.
When both arguments are constants, the comparison is folded at compile
time in `fold-logical.cpp`. However, when the non-BOZ argument is a
variable, folding is skipped and the BOZ literal constant persists in
the expression tree through to lowering.
The lowering implementation wraps the `BOZLiteralConstant]` in a
`Constant<LargestInt>` and feeds it through the existing
`convertConstant` infrastructure. Since BOZ is always a scalar, this
always produces a trivial SSA value. This follows the same pattern as
`gen(Constant<T>)` for the trivial scalar path. The `AddrOfOp` branch
from that template is intentionally omitted because a scalar i128
constant never produces a global reference. The
`outlineBigConstantInReadOnlyMemory` parameter is set to false to make
this intent explicit.
Tests:
- Added BOZ lowering tests to bge.f90, bgt.f90, ble.f90, blt.f90
covering BOZ in first position, second position
- Wider-than-companion BOZ (z'1FFFFFFFF' with i32 companion) lowering
test added to bge.f90

[clang-format] Fix unrecognized qualifiers breaking east-const (#198656)
Long time reader, first time contributor. :3
I've been experimenting with `_Nullable` and `_Nonnull` qualifiers in my
project for which the `.clang-format` configures:
```
QualifierAlignment: Custom
QualifierOrder: [type, const, volatile]
```
This results in the following form:
```cpp
T const* _Nullable const identifier =
```
Formatting as:
```cpp
T const* _Nullable identifier const =
```
Which naturally doesn't compile. This is semi-blocking my project, so I
would like to contribute it reasonably quickly if possible. I'll try to
respond to feedback promptly.
This is possible to fix in a targeted way within the format rule, but I
believe the underlying issue is these qualifiers need to hold true under
`isQualifier`. That seems to fix my issue and may fix others I haven't
discovered. I've extended this to other qualifiers I know of, but not
`__ptrauth` family which seems to have its own special handling.

[CIR] Fix a problem with hoisting allocas out of nested cleanup scopes (#199093)
A recent change to the code that hoists allocas out of a cleanup scope
introduced an assertion that triggers when we're trying to hoist an
alloca that is in a cleanup scope that is nested within the cleanup
scope we're processing. I didn't think that could happen, but it turns
out the LLVM code itself triggers it.
This change removes the assertion and updates the check for the alloca
being contained within the cleanup scope we're processing so that it can
handle the case with nested scopes.

[SLP] Use TrackedVals for trailing scalars in tryToReduceOrdered
The trailing scalar fold passed the original candidate value to
createOp instead of its tracked form. When the same scalar also
appears inside the vectorized window, vectorizeTree replaces its
scalar uses with an extractelement (the scalar is added to the
externally-used values list), so the original instruction is gone
by the time the trailing fold runs. createOp then builds an fadd
that references the stale, replaced scalar, producing invalid IR
or a crash.
Look up the candidate in TrackedVals to retrieve the current
(extractelement when applicable) value, matching the leading
scalar fold loop above.

[CIR] Allow clz/ctz/popcount on u8 and u128 widths (#198911)
libcxx with `-fclangir` was rejecting `cir.clz`, `cir.ctz`, and
`cir.popcount` when the operand type is `!u8i` or `!u128i` — the
verifier only allowed 16/32/64-bit widths even though codegen already
emits the right `llvm.ctlz` / `llvm.cttz` / `llvm.ctpop` intrinsics for
those sizes. That shows up heavily in the May 20 upstream-main libcxx
baseline (`verifier-rejects-pre-pass-ir` bucket).
Widen the TableGen width lists on the three ops to match `bitreverse`
(8 through 128). `builtin-bit.cpp` gains `popcountg` on `unsigned char`,
and `popcountg` / `clzg` / `ctzg` on `unsigned __int128` when
`__SIZEOF_INT128__` is 16, each with CIR/LLVM/OGCG checks.

Follow up to #197311 and based on the feedback on that PR.
One way a Python synthetic formatter can construct a child is with
`SBValue::GetSyntheticChildAtOffset`. However those values were are not
marked as having been generated by `SyntheticChildren`. This means the
previous PR (#197311) did not apply to them as would be expected. The
fix is to call `SetSyntheticChildrenGenerated(true)` on the child values
created in `GetSyntheticChildAtOffset`.

[CIR] Lower __builtin_assume_dereferenceable (#197262)
`__builtin_assume_dereferenceable` was reported NYI by ClangIR. It's
heavily exercised by libcxx via `__memory/valid_range.h`, so most of
`<algorithm>` currently fails to compile under `-fclangir`.
Adds a `cir.assume_dereferenceable` op (pointer + pointer-sized
integer), emits it from CIRGenBuiltin, and lowers it to
```
call void @llvm.assume(i1 true) [ "dereferenceable"(ptr, i64) ]
```
which is what classic Clang's `Builder.CreateDereferenceableAssumption`
produces.
The size operand is widened/narrowed to `intptr_t` at the CIRGen layer
to match classic CodeGen's `IntPtrTy` conversion.
Tests cover the dynamic-size, constant-size, and narrow-integer-size
cases against CIR, CIR->LLVM, and OGCG.

[CIR] Implement getUndefRValue for scalar, complex, and aggregate (#198921)
NYI builtin and call paths in CIR were calling getUndefRValue but the
helper only reported "unsupported type for undef rvalue" and returned
null. libcxx then hit follow-on failures (including scalar-conversion
crashes) on the same translation units that already had other NYI
diagnostics.
Implement the same three cases as classic CodeGen: #cir.undef for
scalar and complex, and an undef.agg.tmp stack slot for aggregates.
Lower cir.const #cir.undef to llvm.undef in DirectToLLVM so emit-llvm
does not assert in the constant op lowering. builtin-undef-rvalue.cpp
covers the __builtin_reduce_or NYI stub path with CIR/LLVM/OGCG checks.

[Polly] Do not invalidate SCEV before codegen (#194677)
ScopInfo expects the state of the IR to reflect the state before
codegen. Invalidating ScalarEvolution/SCEVs has the effect that values
need to be reanalyzed, but this is not possible during codegen where the
CFG and SSA is not yet in a consistent state. That is, we rely on
ScalarEvolution to cache SCEVs from before the codegen phase. If
ScalarEvolution did not already do this, Polly would need to more
aggressively store SCEVs itself (in this case: `canSyntheziseInStmt`)
instead of asking ScalarEvolution.
The SCEV invalidation was introduced in
a61eda769890900903ee65278bf1ee07dfbd4ca5 which unfortunately does not
explain the issue it intends to fix. The added test case passes even
without the invalidation. In any case, SCEVs should represent the state
before codegen.
Fixes #192208

Typically we forgo prefixing things with clang::doc or llvm:: unless

group things to avoid non-internal symbols by placing types in the
anonymous namespace, and more logically grouping things that don't need
to be in the clang::doc namespace.

[CIR] Add CallConvLowering pass + Direct/Ignore ABI rewriting (#195737)
Depends on #195725 (merged).
Stacked on #195725 (PR A1). The diff in this PR is the CIR side; A1 has
the dialect-agnostic infrastructure.
Adds the `cir-call-conv-lowering` pass plus the `CIRABIRewriteContext`
skeleton with handlers for Direct (true pass-through) and Ignore (drop
empty-record args/returns). Subsequent PRs in the split add Extend,
Direct-with-coercion + a new reinterpret op, Indirect/sret,
Indirect/byval, and Expand — each is purely additive because the
rewriter dispatches on `argClass.kind` via a switch with explicit "not
yet implemented" diagnostics for every other kind.
The pass takes one of two driver options: `target=test` uses the test
target from PR A1, and `classification-attr=<name>` reads a pre-built
`DictionaryAttr` from each `cir.func` (also via the helper from PR A1).
It also requires `dlti.dl_spec` on the module and emits a clear
diagnostic otherwise, since classification can't run without
sizes/alignments.
Six `.cir` tests covering the Direct/Ignore behavior via both drivers,
plus the missing-DataLayout error case. `check-clang-cir` and
`check-clang-cir-codegen` both pass with no regressions.
`clang/docs/CIR/ABILowering.rst` gets a short pipeline-position section
(where this pass runs vs CXXABILowering and HoistAllocas, the DataLayout
requirement, the alloca-placement invariant).
The 11 C++ unit tests in #192119 each map onto a `.cir` test in this
series — 6 ported here (Direct passthrough, Ignore arg, Ignore return,
declaration rewrite, plus their call-site variants), 3 deferred to PR B
(Extend), 2 deferred to PR C (Direct-with-coercion). The 5 from #192124
split between PRs D and E. None get dropped, and the original C++ test
file lives only on the closed branches.

[CIR] Fix Cmp-Xchg generation when casting to int (#198924)
We have logic in CIRGenAtomic to handle 'cast float to an int', which
works for most of our atomics. However, compare-exchange uses a second
'val' value, which was not getting cast, which caused a verification
error.
This patch ensures that the correct cast is generated for 'val2' as
well.

[CIR] Implement lowering of atomic-func ptrs (#199045)
This actually is a near-zero effort implementation, since other than an
assertion, we had everything correct. It isn't clear where that
assertion came from (other than an over abundance of caution?). It
doesn't exist in classic codegen, which always counts on the
fallthrough.
However, we ARE missing some ptr-auth work in that area, so a
MissingFeatures is added to be a placeholder for it.

the variable + a null terminator, but the size must be larger!
This patch counds on 'trailing-zeroes' to make sure the null terminator
is in place.

[lldb] Consolidate Target Hook/StopHook scripted state into ScriptedMetadata (#199088)
This is a follow-up to 1b4a578a9f77.
Replace `Target::HookScripted`'s and `Target::StopHookScripted`'s
separate `m_class_name` and `m_extra_args` members with a single
`m_scripted_metadata`, and update `SetScriptCallback to take a `const
ScriptedMetadata &` directly. Drop the now-redundant `args_sp` parameter
from ScriptedHookInterface::CreatePluginObject and
ScriptedStopHookInterface::CreatePluginObject; the Python overrides
construct a StructuredDataImpl from the metadata's args dict for the
dispatched call.
Each hook subclass keeps its own `m_scripted_metadata` member because
the interface's metadata is only set when SetScriptCallback runs the
Python override of CreatePluginObject; the hook needs to hold the
metadata between construction and that callback. Read-side description
printing goes through the new GetScriptClassName() helper which
delegates to m_interface_sp->GetScriptedMetadata(). The two
s.Printf("%s\n", class_name.data()) sites are also converted to
s.Format("{0}\n", class_name).

[lldb] Add Locked<T> and SharedLocked<T> RAII handles in Utility (NFC) (#198941)
Introduce two RAII handles that pair a pointer-like value with a lock on
a caller-supplied mutex.
- Locked<PtrT, Mutex>: holds std::unique_lock<Mutex>. Move-only;
enforces exclusive access. Defaults to std::recursive_mutex to match
LLDB's existing synchronization style.
- SharedLocked<PtrT, Mutex>: holds a reference-counted
std::shared_lock<Mutex>. Copyable — copies share the same reader lock
and the lock releases when the last copy goes away. Defaults to
llvm::sys::RWMutex, the LLDB convention.
PtrT may be a raw pointer, std::shared_ptr, or std::unique_ptr;
convenience aliases LockedPtr/LockedSP/LockedUP and
SharedLockedPtr/SharedLockedSP/SharedLockedUP cover the common
combinations. SharedLocked's borrowed pointer is const-qualified so
readers can't mutate the pointee.

[LLDB] Add a progress event to xcrun invocations (#198953)
LLDB invokes xcrun to find SDKs on disk. This is usually very fast, but
sometimes (after an Xcode update, or when the searched SDK does not
exist) it can take very long (10s or more). The progress event provides
user feedback to explain the hang.
Previously this functionality was in HostInfo, but it may not depend on
Core, so this patch is instrumenting the call sites instead.

IR: Move `simplify_type<(const) Use *>` to Use.h and fix a bug.
These overloads live in User.h because the type of
`User::(const_)op_iterator` is `(const) Use *`, but they do not
necessarily need to be used together with `User`, so let's move them to
Use.h with the canonical type used in the overload for clarity.
There's also a bug where `dyn_cast_or_null` with a `Use *` argument
crashes if the argument is null. Fix it by adding a null check to
these overloads. The null check is expected to be optimized out of the
implementation of `isa`/`cast`/`dyn_cast` because these functions will
unconditionally load from the result of `getSimplifiedValue`.

[NFC][PowerPC][AIX] add explicit code model to 64-bit AIX tests (#199159)
A later PR will propose updating the default code model, so this PR sets
an explicit code model on tests that don't have it. This is strictly
NFC, as we are just setting the existing code model.

[llvm-profgen] Speed up parsing of MMap events (#197871)
During the mmap extraction, `extractMMapEventForBinary()` is invoked
line by line to parse the perf script(usually 100K to 1M+ lines). This
patch tries to early quit when the current line does not contain the
Binary name, and this will help to avoid subsequent parsing
overhead(baseline behavior uses regex to extract the name, returning
false if it doesn't match the current binary).
With this minor change, the execution time of
extractMMapEventForBinary() dropped from 13,600ms to 32ms(-99%) in an
internal workload test(827K lines).

[alpha.webkit.UncountedLocalVarsChecker] Some forms of mutating a guardian variable is ignored (#198950)
This PR fixes a bug in UncountedLocalVarsChecker that it was allowing
mutations to guardian variables within the same scope of a guarded raw
pointer/reference. Since mutating a guardian can affect the lifetime of
a guarded object, we must not consider it as a guardian variable for the
scope.
VisitCXXConstructExpr was just looking for smart pointer's move
constructor but any constructor which takes a guardian smart pointer
using a non-const function argument is problematic so detect all those
cases. Also add VisitCallExpr to detect all forms of function calls to
which a guardian variable is passed via a non-const argument. For
VisitCXXMemberCallExpr, we consider calling any non-const member
function on a guardian variable to be dangerous except conversion
operators (e.g. operator T()).

[libc] Enforce standard identifier validation in hdrgen (#198971)
Implemented validation for standard identifiers in the hdrgen tool to
catch typos and unknown standards. Aggregated standards from all entity
types (macros, types, etc.) for validation, addressing a TODO in
header.py.
Added llvm_libc_ext, stdc_ext, and llvm_libc_stdfix_ext to the canonical
identifiers. Standardised invalid or inconsistently formatted standards
in several YAML files.
This enforces the correctness of any provided standards field but does
not yet require that every entity has one (many entities still inherit
standards from the header level).

Including `SPIRV_AnyFloat` in the majority of types caused fp8 and bf16
to be allowed in ops that are not allowed by float8 and bfloat16
extensions. This patch tries to rectify to only allow fp8 and bf16 in
ops allowed by the respective specs. Additional tests have been also
added to increase the coverage with respect to those types.

[ELF] Reduce symbol partitions to shim binaries (#198718)
The experimental symbol partition feature can move arbitrary symbols and
input sections out of the main partition into named loadable partitions
that consumers extract with `llvm-objcopy --extract-partition`. It is
incompatible with many features, has seen no adoption beyond Chromium's
`build/extract_partition.py`. Chrome hasn't needed this feature for many
years.
The partitioning machinery (per-partition `MarkLive` runs, `moveToMain`,
cross-partition pull in `InputSection::replace`, per-symbol
dynsym/gnuhash/thunk-compat filters, `PartitionIndexSection`,
`copySectionsIntoPartitions`, etc.) does not pull its weight for that.
Remove the partitioning brain and keep a minimal shim shell.
`Symbol::partition` is deleted; every dynsym add goes to
`ctx.mainPart`. `ctx.partitions` wraps a `std::vector<Partition>`
whose iterator yields only the main partition; shim partitions live
in `storage[1..]` and are reached via `shims()`. The two paths that
actually emit shim binaries (`createPhdrs` and `pageAlign` in
Writer.cpp) name `shims()` directly.
Shim partitions carry no per-partition synthetic content; the
extracted shim is just an ELF header plus PT_PHDR/PT_LOAD.
`llvm-objcopy --extract-partition` keeps working but
`--dump-section .note.gnu.build-id` on a shim no longer finds
anything. Features that previously used `dlopen()` to lazy-load a
feature partition now live in main and are always loaded.

[clang] Avoid invalidating specialization lookup (#196533)
Fixes a use-after-free in `ASTReader::LoadExternalSpecializationsImpl`
when loading external specializations with `-ftime-trace` enabled.
This resolves the https://github.com/llvm/llvm-project/issues/196482 and
builds upon the https://github.com/llvm/llvm-project/pull/172658
The function kept a pointer into `SpecLookups`:
```cpp
LookupTable = &It->getSecond();
```
Then it constructed a `TimeTraceScope` whose name callback calls
`getNameForDiagnostic`. That call may deserialize additional AST state
and mutate `SpecLookups`, invalidating the saved pointer before it is
later used for:
```cpp
LookupTable->Table.find(HashValue);
```
This is observed as an ASAN `heap-use-after-free` in:
```text
MultiOnDiskHashTable<LazySpecializationInfoLookupTrait>::find
ASTReader::LoadExternalSpecializationsImpl
```
The fix computes the template-argument hash and copies the lazy
specialization lookup result before constructing the time-trace scope.
This avoids retaining a `DenseMap` iterator or pointer into
`SpecLookups` across code that may trigger deserialization.
Validation from a local reproducer:
- Unpatched Clang + PCH + `-ftime-trace`: ASAN heap-use-after-free.
- Unpatched Clang + same PCH without `-ftime-trace`: passes.
- Patched Clang + PCH + `-ftime-trace`: full downstream wasm build
passes.
I cannot attach the original PCH-based reproducer publicly because the
PCH contains private project paths and serialized private headers, but
the reduced failing source no longer contains project logic and the ASAN
trace points directly at invalidation inside
`LoadExternalSpecializationsImpl`.

[MLIR][Linalg] Specialize more binary elementwise ops (#192290)
Extends the matching logic for `linalg.generic` ops that can be
represented as named op or `linalg.elementwise` to cover all variants
currently supported by `RegionBuilderHelper::buildBinaryFn`. We
previously detected only `add`, `sub`, `mul` and `div` for floating
point types.
I combined the detection for unary and binary functions to make it
tractable to morph operations such as
```mlir

// ...
%c123_i32 = arith.constant 123 : i32
%0 = linalg.generic
{indexing_maps = [#map, #map], iterator_types = ["parallel"]}

^bb0(%in: i32, %out: i32):
%v = arith.addi %c123_i32 , %in : i32
linalg.yield %v : i32
} -> tensor<?xi32>
```

```mlir
#map = affine_map<(d0) -> ()>
#map1 = affine_map<(d0) -> (d0)>
// ...

[VPlan] Assert that replacement types match in VPUser::setOperand (NFC). (#195891)
Add assertion to VPValue::setOperand to check if types of the new
operand matches the old operand.
This makes it easier to catch replacements with incorrect types at the
source, instead only later during verification.
A few places currently preform replacements with mis-matching types,
which only get fixed up later. Update those to avoid type-violation.

[flang-rt] Remove library dependency from flang-rt to offload (#198793)
Summary:
We need the offload project's RPC thread to handle the IO requests
originating from the GPU. Previously we did the 'easy' solution and just
linked this handler directly into the offload proejct. This is not ideal
because it prevents people's ability to build and configure libraries
separately.
This PR inverts the dependency, flang-rt now conditionally enables
support using the existing RPC callback mechanism. The cost is that
every flang-rt program now pays the cost of a boolean compare, the
benefit is the libraries are now independent of each-other.

[SLP] Retry vectorization of FMA candidates after block processing
fadd/fsub instructions that canConvertToFMA returns valid for were
unconditionally skipped in tryToVectorize, causing regressions
where SLP failed to vectorize loops containing such patterns even when
FMA formation never fires.
Collect skipped FMA candidates during vectorizeChainsInBlock and retry
them with AllowFMACandidates=true after all other instructions in the
block have been processed. The cost model still rejects the retry when
actual FMA formation is more profitable (e.g. FMA4 on bdver2), so
existing FMA-profitable cases are unaffected.

[lldb] Fix dummy target filtering regression in CommandInterpreter (#198949)
In #198429 (reland), CommandObject::GetTarget() was tightened to return
nullptr instead of the dummy target when no real target exists, unless
the command explicitly opts in via eCommandAllowsDummyTarget or standard
target requirements
However in CommandInterpreter::GetExecutionContext(bool
adopt_dummy_target) :
```
ExecutionContext
CommandInterpreter::GetExecutionContext(bool adopt_dummy_target) const {
return !m_overriden_exe_contexts.empty()
? m_overriden_exe_contexts.top()
: m_debugger.GetSelectedExecutionContext(adopt_dummy_target);
}
```
If m_overriden_exe_contexts is not empty, the method returned the top
context immediately—completely ignoring the adopt_dummy_target argument
requested by the command object.
Because of this:
1. During sourced script runs, process attach received the dummy target
as its execution target (since adopt_dummy_target = false was ignored).
2. It bypassed the target == nullptr check and proceeded to attach
directly to the dummy target.
3. As the dummy target was never registered in m_target_list , the main
target list remained empty ( No targets. ), causing all subsequent
commands (e.g., setting breakpoints or continuing) to fail with invalid
target errors.
### The Fix:
lldb/source/Interpreter/CommandInterpreter.cpp :
Respect adopt_dummy_target = false in GetExecutionContext when a dummy
target is present in the overridden execution context stackm so that if
adopt_dummy_target is false and the overridden context on the stack
contains the dummy target, we clear the context before returning it.
This forces GetTarget() to return nullptr as originally intended.
### Test:
• lldb/test/Shell/Commands/process-attach-dummy.test :
Add a new standalone Lit shell test to replicate this scenario. The test
sources a command sequence executing process attach when no target
exists, and verifies that target list successfully registers the newly
created real
target ( target #0: <none> ) instead of leaving the list empty.

[LV] Avoid stale VPTypeAnalysis cache in convertToStridedAccesses (#199222)
VPlanTransforms::convertToStridedAccesses calls
VPWidenMemoryRecipe::computeCost, which uses VPTypeAnalysis in
VPCostContext to infer the pointer type of the load address. However,
CachedTypes in VPTypeAnalysis may be invalidated since earlier
transformations in tryToBuildVPlan could erase recipes from the plan.
This pollutes the cache with stale types.
Fix this by creating a new VPCostContext locally scoped to
convertToStridedAccesses, ensuring VPTypeAnalysis reflects the current
plan state. This serves as a quick fix to prevent accidental reuse by
future transformations.

[lldb] Adopt LockedPtr in Module (NFC) (#199160)
Follow-up to #198941, which introduced Locked<T> and SharedLocked<T>.
Add GetObjectFileLocked, GetSymbolFileLocked, GetSymtabLocked, and
GetSectionListLocked alongside the existing accessors.
The locked variants cover two things:
1. They prevent the pointer from being swapped out from under the
caller. The old getters take m_mutex only during lazy initialization and
release it before returning. The unique_ptr or shared_ptr that owns the
pointee can therefore be reassigned by another thread while the caller
still holds the raw value. LockedPtr keeps the Module mutex held
alongside the borrowed pointer, pinning the binding for the lifetime of
the handle.
2. They serialize access to the pointee itself. This is not new, the
classes in question were already relying on the Module mutex for
synchronization.
Migrate the four call sites in Module where the existing patter maps to
a single LockedPtr.
The legacy raw-pointer getters remain so call sites can migrate
incrementally.

[clang] Use FileError in FileManager::getFileRef, getDirectoryRef (#199126)
Most callers are unchanged, since they either ignore the specific error
or have their own formatting of the error that includes both the path
and the errorToErrorCode-unwrapped value. However, for clients that just
forward the error it's helpful to ensure we do not lose track of the
filename that the error is associated with, so use FileError.
Incidentally remove two uses of errorToErrorCode that were being used
instead of consumeError; in both cases getOptionalFileRef was more
appropriate.

[flang-rt] Remove fallback if RPC headers not found (#199211)
Summary:
These are stored in the libc/shared and have a unified CMake helper to
find them. Likely these will be a more core dependency as LLVM uses them
for constexpr math, libcxx uses it, and compiler-rt will probably use
bits of it.
The original intention was to allow building flang-rt with a partial
checkout, but i don't think this is a reasonable use-case and I do not
think this exists in practice.

[FileCheck] Resurrect overflow tests (#198136)
D150880 (landed as 0726cb004718) uses `APInt` to eliminate most integer
overflow issues from FileCheck numeric variables. It also removes the 4
tests in `llvm/test/FileCheck/match-time-error-propagation`.
While the elimination of overflow issues reduces the importance of those
tests, the tests still seem worthwhile. Without them, I see no test that
exercises the "unable to substitute variable or numeric expression:
overflow error" diagnostic in FileCheck input dumps.
This patch resurrects those tests and updates them to exercise the
remaining unsigned underflow case.

[docs] update noescape semantics to disallow free (#195973)
This changes the documented semantics of the `noescape` attribute to
disallow freeing the pointer, and allow escapes of the integer value of
the memory address, as discussed in
https://discourse.llvm.org/t/rfc-updating-the-semantics-of-the-noescape-attribute/90326.
It also clarifies that the attribute may only be used to annotate the
outermost pointer level of nested pointer parameters.

[FileCheck] Refactor -dump-input test (#198137)
This PR is stacked on PR #198136.
This patch refactors `llvm/test/FileCheck/dump-input/annotations.txt` to
improve maintainability and coverage and to prepare for the upcoming
implementation of search range annotations.
Lit substitutions
=================
The test repeats the same basic set of RUN lines *many* times. This
patch encapsulates those in lit substitutions to improve
maintainability. By doing so, it also helps to ensure more consistent
coverage of all cases and thus slightly expands coverage.
-strict-whitespace
==================
Via those substitutions, this patch adds `-strict-whitespace` throughout
the test, and it drops the initial `-strict-whitespace` case because it
is then redundant. That causes many whitespace changes throughout the
test, so this patch is easier to read with `git diff -w`.
When I originally wrote the test, I thought maintaining it would be too
painful with `-strict-whitespace`. However, I now think it is important
for usability to thoroughly check that annotations are correctly aligned
with the input, especially given the upcoming search range annotations.
-dump-input-label-width
=======================
To address that anticipated maintenance pain, and to make the above
change easier to implement, this patch also implements a new hidden
FileCheck option, `-dump-input-label-width`. It enables tests like this
one not to have to fuss with fluctuations in the label column width that
are caused when varying the verbosity options. I do not anticipate this
option will be used outside FileCheck's own test suite.
Splitting directive blocks
==========================
To improve readability, this patch splits apart directive blocks where
the same annotations appear multiple times with small differences at
different verbosity levels. See new header comments for details.

hours.
Long compilation time in reduce.cu was only exposed by jump-threading.
In my view the primary causes were due to inlining, SROA tripling the IR
code size, and SSA updating 26K phi-nodes resulting in an O(N^2) search
for duplicates. #195744 limits phi search times.
This reverts commit a76750e6de6aba2223097dc505578556ec245d50.

For now this is limited to cases where the first operand is a constant,
so the SExt can be folded to a new constant. This can be relaxed in the

[offload] Use device memory for the multithreaded kernel lanuch test (#199132)
This commit modifies the multithreaded kernel launch test to use device
memory instead of managed memory. The test is reported to be failing
intermittently in systems where concurrent managed memory access is
not supported. This is the case for NVIDIA devices that do not support
CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
The concept of concurrent and coherent managed memory access should
be exposed to liboffload users somehow, e.g., adding it as device property,
so it is clear what execution patterns are allowed with managed memory.
However, this test is just testing concurrent kernel launches. This commit
fixes it until we decide how to proceed with the guarantees on that type of
allocations.

[OpenCL] Fix image2d_t qualifier for intel_sub_group_block_write_ui (#199232)
The intel_sub_group_block_write_ui[2,4,8] overloads for image2d_t were
declared with a read_only qualifier, both in opencl-c.h and in
OpenCLBuiltins.td. A write operation cannot target a read_only image,
and
the base intel_sub_group_block_write together with the analogous _us,
_uc
and _ul aliases all correctly use write_only image2d_t.
Per the cl_intel_subgroups_short [1], cl_intel_subgroups_char [2] and
cl_intel_subgroups_long [3] specifications, the _ui aliases are added
"for
naming consistency [...] There is no change to the description or
behavior
of these functions" relative to the cl_intel_subgroups base, which uses
write_only image2d_t for writes.
The typo was introduced in b833bf6ae14f and preserved across all
later edits to this area.
Switch the qualifier from read_only to write_only in both opencl-c.h and
OpenCLBuiltins.td, and update intel-subgroups-builtins.cl to match the
corrected signature (the existing test was exercising the buggy
overload).

[OpenCL] Add Intel subgroup buffer prefetch and local block I/O builtins (#199258)
Add cl_intel_subgroup_buffer_prefetch and
cl_intel_subgroup_local_block_io
declarations to OpenCLBuiltins.td and cover them with header-free SPIR
tests.
This keeps the generated OpenCL builtins in sync with opencl-c.h for the
Intel subgroup buffer prefetch and local block I/O extensions.
Per the cl_intel_subgroup_local_block_io specification, the _ui local
aliases (intel_sub_group_block_read_ui*, intel_sub_group_block_write_ui*
with __local pointer) are declared under
FuncExtIntelSubgroupLocalBlockIO
alone, without a char/short/long prerequisite. A dedicated test
(intel-subgroup-local-block-io-ui-without-char-short-long.cl) verifies
that
they resolve when only cl_intel_subgroup_local_block_io is active.

-----------
[CIR] Include union tail pad in getTypeSizeInBits (#198361)
Padded CIR unions (e.g. libstdc++ `std::string` SSO layout) carry a
trailing byte-array member so the record matches the AST layout size.
`RecordType::getTypeSizeInBits` was returning only the largest-aligned
member and ignored that tail, so the CIR view of the union was 8 bytes
smaller than what `LowerToLLVM` emits. Parent structs then picked up
a spurious trailing pad via `insertPadding`, arrays of those structs
used the wrong stride, and heap allocations could be overrun (Eigen's
`array_of_string` hits this directly).
The fix adds the padding member's size when the union is marked
`padded`, so struct size, GEP strides, and `new T[n]` allocation sizes
match OGCG. Regression test models the SSO-shaped record and checks
the 96-byte `new` for three elements.

[Clang][CodeGen] map `noescape` to capture(address) (was capture(none)) (#199281)
`capture(none)` has very restrictive semantics and an easy footgun to
accidentally fire some UB into your code with. Most significantly it
does not allow any visible side-effects of whether a pointer was null or
not to escape the function. This means that the function cannot perform
different side effects depending on whether a pointer marked `noescape`
is null. Relax this to `captures(address)`, which allows information
about the numerical address to escape the function, but no provenance
(i.e. nothing that could be dereferenced) may escape.
As discussed in
https://discourse.llvm.org/t/rfc-updating-the-semantics-of-the-noescape-attribute/90326.

[RISCV][TTI] Make getShuffleCost check we have a vector before querying getVectorElementCount (#199286)
Fixes the assert reported here:
<https://github.com/llvm/llvm-project/pull/198446#issuecomment-4522589671>
I believe this happens when the element type isn't a legal RVV element
type and so has been scalarised by type legalisation.
Adding this guard also matches the AArch64 implementation.
The test change is LLM generated.

covering both the CodeGen direct path (`emitCallToBadCast`) and the

- Drop the now-fulfilled `MissingFeatures::opFuncNoReturn` entry and
the corresponding TODO/assert at the lone caller in
`LowerItaniumCXXABI.cpp`.
- Update FileCheck expectations in `dynamic-cast.cpp`,
`dynamic-cast-exact.cpp`, and `abi-lower-after-unreachable.cpp` to
require the `{noreturn}` attribute on the lowered
`cir.call @__cxa_bad_cast()`.

Update the auto-upgrade for llvm.nvvm.abs.i and llvm.nvvm.abs.ll to use
the generic llvm.abs intrinsic with is_int_min_poison=true. The previous
expansion used neg/icmp/select which gives defined INT_MIN -> INT_MIN
behavior, but loses the poison/undefined signed-min semantics needed for
NVPTX to select PTX abs.s32 and abs.s64 instrucitons when the source
operation permits signed-min overflow to be undefined. This is a
followup to #183851 . Using llvm.abs(..., true) preserves intended IR
semantics and lowers through the new ABS_MIN_POISON. We also update the
tests and add NVPTX CodeGen coverage for the legacy nvvm abs intrinsics.

Some Windows bots using MSVC 2019 and 2022 get assertion errors in the
clang-doc lit tests (see
[here](https://github.com/llvm/llvm-project/pull/198066). This seems to
be due to MSVC having trouble with a correctly initializing structures
using std::initializer_list when embedded in a struct declared with
constexpr.
This workaround changes constexpr to const in a struct definition to
avoid this issue.

[SimplifyLibCalls] Fix optimizeFdim for Inf-Inf cases (#199306)
fdim(x,y) is defined as

optimizeFdim computed fdim(x,y) as max(x-y, +0). This is not correct
when x == y == +/-Inf; the result should be 0, but this optimization
returns NaN.
I was surprised by this bug because there's even a testcase checking the
incorrect behavior. But returning 0 matches the description in C99 and
POSIX, where, just to be extra clear, the spelling of the piecewise
function is
NaN if either input is NaN
x - y if x > y
+0 if x <= y
Returning +0 also matches the behavior of libc on my machine
gcc.godbolt.org.

LibCallSimplifier can fold a libcall to fmod to an frem instruction if

fmod(x, y) sets errno if x == +/-Inf or y == 0. The old code assumed
that this was also a sufficient condition to prove that the result is
not NaN, and so unconditionally set the nnan fmf on the new frem
instruction. That's not sound; e.g. fmod(x, NaN) == frem(x, NaN) ==
NaN.
We don't actually have to worry about propagating the `nnan` flag;
B.CreateFRemFMF does it for us automagically.

[RISCV] Reserve all sub-registers of user reserved GPRs (#199302)
When a GPR is reserved by the user (e.g., via `-mattr=+reserve-x27`)
or marked as constant, only the top-level register was being marked
reserved in `RISCVRegisterInfo::getReservedRegs`. Its sub-registers
(`X27_W` and `X27_H`) remained unreserved.
This broke `LiveIntervals` when register pressure tracking was enabled
by #115445. Because the sub-registers were not reserved, the register
unit was considered non-reserved, causing `LiveIntervals` to track its
liveness and crash in the Machine Verifier due to the reserved
register missing from basic block live-in lists.
Instead, we should ensure that reserving a register also reserves all
of its sub-registers, so that the register unit is correctly
identified as reserved and ignored by `LiveIntervals`.

[compiler-rt] Use `size_t` rather than `int` for first argument to `__atomic_load_c` et al. (#197519)
I noticed this discrepancy in emscripten when trying to test 128 bit
atomics under wasm64:
https://github.com/emscripten-core/emscripten/pull/26937
The LLVM CodeGen appears to use `size_t` in this position when it
generates calls to these functions.
This doesn't effect other platforms I imagine because they don't require
signature checking at the linker level.
This doesn't effect wasm32 where size_t and int are the same size.

[X86] LowerFLDEXP: convert widened int exponent to FP before SCALEF (#199263)
For vector ldexp cases that LowerFLDEXP implements by widening to a
512-bit SCALEF operation, the code widened both X and Exp but passed
the widened integer exponent directly to SCALEF, which interprets
its inputs as IEEE-754 floats.
Convert the widened integer exponent to FP and pass that to SCALEF.
Reproducer (clang -O2 -mavx512f repro.c -o repro && ./repro):
```
#include <stdio.h>
typedef float v4f __attribute__((vector_size(16)));
typedef int v4i __attribute__((vector_size(16)));
__attribute__((noinline))
v4f ldexp_v4(v4f x, v4i e) {
return __builtin_elementwise_ldexp(x, e);
}
int main(void) {
v4f x = {1, 2, 4, 8};
v4i e = {1, 2, 3, 4};
v4f r = ldexp_v4(x, e);
printf("got %g %g %g %g\n", r[0], r[1], r[2], r[3]);
printf("expected 2 8 32 128\n");
}
```
Before this patch, ldexp_v4 lowered to the following (note no
vcvtdq2ps):
```
vmovaps %xmm1, %xmm1
vmovaps %xmm0, %xmm0
vscalefps %zmm1, %zmm0, %zmm0 ; xmm1 still holds integer bits
```
so the program printed "got 1 2 4 8".

Remove the special cost logic for loads predicated by the header mask,
as it does not accurately reflect the cost of the generated VPlan.
Unmasking the load can only be done in general if we don't unroll or if
the address is actually uniform-across-vf-and-uf. The former we cannot
really determine before selecting the VF as UF is picked after VF. The
latter is not really useful in practice.

[X86][GISel] Fix carry-in for selectUAddSub. (#199261)
When G_UADDE/G_USUBE was chained off a previous G_UADDE/G_UADDO/
G_USUBE/G_USUBO, selectUAddSub re-materialized EFLAGS.CF from the
previous SETB byte using CMP r, 1. That computes (r - 1) and sets
CF iff r < 1 unsigned, i.e. CF = (r == 0) -- the inverse of the
desired carry. The following ADC/SBB then consumed the wrong CF and
produced an off-by-one upper word; e.g. `add i128 0xFF..FF, 1` under
-global-isel returned hi=0 lo=0 instead of hi=1 lo=0.
Emit NEG r instead: NEG sets CF iff its operand is non-zero, matching
the SETB byte. NEG is a two-address (tied) instruction, so emit it
into a fresh virtual register rather than redefining the carry-in
vreg.
C reproducer (compile on x86_64-linux-gnu and run):
```
// clang -O2 -fglobal-isel repro.c -o repro && ./repro
#include <stdio.h>
__attribute__((noinline))
__int128 add128(__int128 a, __int128 b) { return a + b; }
int main(void) {
__int128 a = (__int128)0xFFFFFFFFFFFFFFFFULL;
__int128 r = add128(a, 1);
unsigned long long lo = r, hi = r >> 64;
printf("hi=0x%llx lo=0x%llx\n", hi, lo);
return (hi == 1 && lo == 0) ? 0 : 1;
}
```
Without -fglobal-isel: prints "hi=0x1 lo=0x0", exits 0.
With -fglobal-isel: prints "hi=0x0 lo=0x0", exits 1.
The buggy code-gen emits the inverted-carry sequence (clang trunk,
pre-fix):
```
add128:
movq %rdx, %rax
addq %rdi, %rax
setb %dl
cmpb $1, %dl # CF = (dl == 0), inverse of intended
adcq %rsi, %rcx
movq %rcx, %rdx
retq
```

[llvm,clang] Don't assume non-erased DenseMap entries remain valid after erase. NFC (#198982)
In preparation for switching DenseMap from tombstone deletion to
backward-shift deletion, update call sites that reuse an iterator or a
bucket reference after erasing another entry from the same map.
These work under tombstone deletion because unrelated buckets stay put,
but backward-shift deletion relocates entries to close the gap.
Add DenseMap::remove_if, similar to SmallPtrSet::remove_if, as
replacement for erase-while-iterating, and use it where applicable.

[CodeGenPrepare] Report an error if ProfileSummaryAnalysis is not available (#199268)
CodeGenPreparePass can't declare ProfileSummaryAnalysis as required,
because PSA is a module-level analysis, but CFP is a function-level pass.
Therefore it accesses PSA using getCachedResult, and PSA might be null.
In practice this doesn't happen, because the CGP pass pipeline
preparation code ensures that PSA is present. But if you invoke
CGP via opt -passes=codegenprepare, then it's not
there, and we segfault.
Fix for https://github.com/llvm/llvm-project/issues/173360.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

[SLP] Ensure TreeCost is scaled for ordered fadd reductions (#199388)
Resolves #199267
Addresses an issue where `getScaleToLoopIterations()` can return 1 on
isolated SLP trees because `UserTreeIndex` is invalid. This prevents
`TreeCost` from scaling alongside `ReductionCost`, causing the cost
model to incorrectly treat an unprofitable vector reduction as
profitable.
This patch passes the reduction root instruction down into
`calculateTreeCostAndTrimNonProfitable` and the underlying scale
calculation so `getScaleToLoopIterations` can get the correct block
context.

GCC has fixed SFINAEing on `delete` since at least GCC 11, so we can
properly constrain the constructor.

[mlir] Don't assume non-erased DenseMap entries remain valid after erase. NFC (#199365)
Like the preceding llvm/ change, fix MLIR sites that reuse an iterator
or bucket reference after erasing from the same map, in preparation for
backward-shift DenseMap deletion which relocates surviving entries.
Use DenseMap::remove_if in ThreadLocalCache::clearExpiredEntries and the
RootOrdering cycle contraction (deferring the in-cycle graph erases
until
after iteration). ThreadLocalCache::get reads the value into a local and
bufferizeOp snapshots the worklist before folding, since those erases
re-enter via a rewriter listener.

[libc++] remove duplicate assertions for void/reference const any_cast (#199425)
For test cases of the const overload of any_cast, such as:
```C++
void test() {
std::any a = 0;
const std::any& a2 = a;
(void)std::any_cast<int&>(&a2);
}
```
(And similarly for void).
The problem is that the assertions are implemented both in the const and
non-const any_cast overloads, but since the const overload delegates to
the non-const overload, that ends up producing the same assertion twice.
This separates those test cases, because those assertions are
implemented in the function body, and that's only instantiated once per
specialization, not once per use.

CodeGen (`clang/lib/CodeGen/TargetBuiltins/ARM.cpp`): bitcast both

[AMDGPU] Fix v_dot4_i32_i8 alias to set neg_lo modifiers (#197998)
Fixes issue here https://github.com/ROCm/ROCm/issues/6126
The `v_dot4_i32_i8` assembly alias was not setting the `neg_lo` modifier
bits when converted to `v_dot4_i32_iu8`, which causes signed int8
operands to be treated as unsigned.
For example: `q=[1,-1,1,-1], k=[1,1,1,1]`: expected 0, returned 512. The
instruction is computing `1*1 + 255*1 + 1*1 + 255*1 = 512` ; treating
`-1 (0xFF)` as `255`.
On AMD GFX11+, the native `v_dot4_i32_i8` instruction doesn't exist. The
hardware provides `v_dot4_i32_iu8` with `neg_lo` modifier bits to
control signedness of each operand. The compiler correctly lowers
`v_dot4_i32_i8` intrinsics by setting `neg_lo:[1,1,0]`, but inline
assembly using the `v_dot4_i32_i8` mnemonic bypasses this lowering and
goes directly to the assembler.
The assembler accepted `v_dot4_i32_i8` as a simple mnemonic alias but
didn't set the neg_lo modifiers, this results in all-unsigned behavior
which is wrong.
This patch adds assembly parser logic to detect when `v_dot4_i32_i8` is
used and automatically inject `neg_lo=0x3` *(src0 and src1 signed, src2
unsigned)* during operand conversion.

The original crash from the reproducer no longer reproduces after

Also added regression tests for the crash:

SinkInteriorBorrow(std::string *dest, int n) : dest_(dest->data()) { // expected-warning {{parameter which escapes to a field is later invalidated}}

This is arguably an enhancement rather than a bugfix. But
AtomicExpandPass already tries to support some non-integer atomic ops
using cmpxchg by bitcasting to/from an integer type. We're just missing
this one path used by atomic load. Seems easy enough to support it.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

clang-offload-bundler incorrectly errors on multi-CCOB binaries (#182579)
Issue: https://github.com/ROCm/llvm-project/issues/448
Objects can have multiple Clang Compressed Offload Bundles (CCOB) in the
.hip_fatbin section. This happens when there are multiple
translation/compilation units built and then linked together into an
Archive or Shared Object. The resulting .hip_fatbin section will have
multiple offload bundles delimited by the magic string "CCOB" (on a 4k
alignment boundary). The Clang Offload bundler API, when a List of
bundle entries is requested, was not properly iterating (looping) over
each separate bundle.
REPRODUCTION

This prevents iterator invalidation when sinking or hoisting recurrence

- Take the implicit object's actual type (e.g., the type before any

`isGslOwnerType` call sites with the same pattern (e.g.,
`isGslOwnerType(MCE->getImplicitObjectArgument()->getType())` in
`VisitCXXMemberCallExpr`) lack a real-world trigger today and are
deferred to a follow-up.
- Unify the GSL Owner checks inside `shouldTrackImplicitObjectArg` so
they share a single source of truth.

[lit] Normalize RLIM_INFINITY to "infinity" in print_limits.py for Python 3.15+ (#190953)
Python 3.15 changed resource.getrlimit() to return the platform's
maximum value (e.g., 18446744073709551615 on 64-bit systems) instead of
-1 for RLIM_INFINITY. This breaks lit tests that expect -1 for unlimited
resource limits.
This patch normalizes the return value to "infinity" when it equals
RLIM_INFINITY to maintain compatibility with existing tests across all
Python versions.
Fixes test failure: shtest-ulimit-nondarwin.py
Expected: RLIMIT_FSIZE=-1
Got: RLIMIT_FSIZE=18446744073709551615

It does not look like this has been used anywhere since it was
implemented. I see no uses of it in LLVM, anywhere in our internal
monorepo, or across the entirety of Github outside of other copies of
LLVM tests. Given that, remove it. The intended use case around SSO ASan
string annotations is also likely to be significantly reworked soon.

would start to emit invalid profile information after

best redundant with BFI. So we restrict metadata emission to only if we
have a sufficient number of values for the VP metadata to be valid.

[RISCV][P-ext] Fold bitcast of v4i8/v2i16 const splat to scalar on RV64 (#199513)
clang lowers `int8x4_t f(int8x4_t a) { return ~a; }` to a
bitcast-wrapped vector xor with splat(-1). v4i8/v2i16 aren't legal on
RV64, so the xor gets scalarized to i64 with the constant still wrapped
in BITCAST:
`i64 = xor X, (bitcast (v8i8 splat -1))`
The scalar `not` PatFrag (xor X, -1) requires a literal constant and
can't see through BITCAST, so XORI -1 (= `not`) misses and we emit `li
-1; xor` (2 insns). The v8i8/v4i16/v2i32 paths stay at vector level and
match the bitcast-aware vector `vnot` td-pat, so they're fine; only the
widened-from-v4i8/v2i16 path falls through to scalar `not`.
Fix it by folding the bitcast of a v4i8/v2i16 constant splat to a scalar
i32 constant pre-legalization. Type promotion sign-extends to i64 -1 and

[CodeGenPrepare] splitMergedValStore: don't split atomic stores. (#199592)
splitMergedValStore notices when you do e.g.
z = x | (y << 32)
store z
and may split this up into 32-bit two stores, of x and y, depending
e.g. on the type of x and y.
It skips this optimization for volatile stores, but currently does NOT
skip it for atomics (!!). So an atomic store can be split up into two
(non-atomic!) stores.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

[AArch64] Add support for MSVC-style mangling for SVE (#196738)
Fixes #196170
Recent MSVC toolchains added support for AArch64 SVE types and use
dedicated builtin manglings such as `$_CD` instead of the older
artificial `__clang` struct manglings.
Update Clang's Microsoft mangling implementation to match MSVC for
supported SVE builtin types.
Unsupported SVE types continue using the existing artificial tag
mangling until MSVC gains support for them.
Adds representative coverage for:
* scalar SVE types
* tuple/vector SVE types
* fallback manglings for unsupported types

[NFC] [clangd] [C++20] [Modules] Fix false duplicate module warning for equivalent paths (#199343)
When checking for multiple source files declaring the same module, the
comparison used raw string equality on file paths. This causes false
positives when the same file is represented by different but equivalent
path strings.
Use pathEqual(normalizePath(...), normalizePath(...)) instead to compare
canonical paths, consistent with how clangd handles path comparisons
elsewhere.

3. Online packing - loop peeling is now based on `step` size,
4. Extends support for `f8` lowering (`mx-fp8` lowering will be
supported after vector.contract has `mx` support).

- `approx = true`: fast hardware approximation (`div.approx[.ftz].f32`), 2 forms -- f32 only.
- `full = true`: full-range approximation (`div.full[.ftz].f32`), 2 forms -- f32 only.

[IR] Inline remove_if in PMDataManager::removeNotPreservedAnalysis (#199571)
PR #198982 rewrote removeNotPreservedAnalysis to use DenseMap::remove_if
with one predicate shared across two call sites. The predicate is always
inlined; the cost is that two call sites make
DenseMapBase::remove_if<...>
itself emit out of line instead of inlining into the caller. As this
runs
after every modifying codegen pass (legacy PM), it shows up as a small
instructions:u regression, most visibly at -O0 where the legacy codegen
PM
is a large fraction of compile time:
https://llvm-compile-time-tracker.com/compare.php?from=69a5cf515fd317bcf918e48de9137dd8549870c5&to=6302439f5aaea6cb776d8ceb5c2ef9108fccf702&stat=instructions%3Au
Collect the maps into a SmallVector and prune them from a single
remove_if
call site, so the instantiation is inlined again.

[DenseMap] Invalidate iterators on erase (#199369)
Tighten DenseMap's `erase` contract so that, like `insert` and `grow`,
it invalidates iterators and references obtained before the call.
Under the current tombstone-based deletion this is purely an
LLVM_ENABLE_ABI_BREAKING_CHECKS check — the bucket array is not actually
mutated for other entries — but it surfaces stale-iterator-after-erase
patterns now rather than when DenseMap's deletion scheme changes.
Mirrors the SmallPtrSet change in #96762, which dropped tombstones in
small mode and likewise had `erase` invalidate iterators.
Depends on #198982 and #199365

-----------
[Clang][Sema] Fix crash in __builtin_dump_struct with immediate callables (#192880)
## Motivation
`ComplexRemove` (used by `Sema::PopExpressionEvaluationContext` to strip
nested `ConstantExpr` wrappers) inherits the default
`TreeTransform::TransformOpaqueValueExpr`, which asserts on any
`OpaqueValueExpr` with a non-null `SourceExpr` unless a binding has
already been set up.
`__builtin_dump_struct` binds the record pointer to an `OpaqueValueExpr`
inside a `PseudoObjectExpr`. When the callable argument is
immediate-escalated (e.g. via `__builtin_is_within_lifetime`),
`RemoveNestedImmediateInvocation` roots `ComplexRemove` inside the PSE's
semantic form, reaching that OVE without the binding the assert expects
- triggering a crash.
## Closing Issues
Closes #192846

[RISCV] Fix fixed-length masked.{u,s}{div,rem} lowering not converting operands (#197913)
Similar to #197724, but this time I also somehow forgot to convert the
operands to scalable vectors. I'm surprised that nothing asserted here,
since SDT_RISCVIntBinOp_VL has a type profile constraint that the
operands and result types need to be the same.

-----------
[LoongArch] Fix musttail with indirect arguments by forwarding incoming pointers (#198965)
When a `musttail` call passes arguments indirectly (fp128 on LA32, i128
on LA32), the backend allocates a stack temporary and hands the callee a
pointer. The tail call deallocates the caller's frame, and the pointer
dangles.
Fix by forwarding the incoming indirect pointers instead. They point to
the caller's caller's frame, which stays valid after the tail call.
Forwarded formal parameters reuse the pointer directly; computed values
get stored into the incoming buffer first.
The pointers are saved in virtual registers (`CopyToReg`/`CopyFromReg`)
rather than SDValues. The SelectionDAG is cleared between basic blocks
and musttail calls can appear in non-entry blocks, so storing raw
SDValues across BBs is unsound (this was the bug that led to the revert
in 501417baa60f). The vreg save only fires when the function has
musttail calls; other functions see no codegen change.
Non-musttail tail calls with indirect args are still rejected.
This uses the same strategy as the corresponding RISC-V fix (#185094).

[mlir][mem2reg] fix assert for indirect blocking uses inside regions (#199193)
When adding new blocking uses created by the interface of a previous
blocking uses (typically forwarding the blocking uses to the op result
users), the mem2reg framework was assuming that the new blocking uses
are in the same region as the original blocking use, which is not true
in general and lead to the assert:
`Transforms/Mem2Reg.cpp:743: void
{anonymous}::MemorySlotPromoter::removeBlockingUses(mlir::Region*):
Assertion `op->getParentRegion() == region && "all operations must still
be in the same region"' failed.`
This patch fixes this by adding the new uses into the userToBlockingUses
for the region of the new blocking uses.

[Coroutines] Allow rematerialization of unary operators and selected intrinsics (#197698)
All of those can be cheaply recomputed when the coroutine has resumed.
Before this change, results of unary operators and intrinsics were
spilled into the coroutine frame and reloaded on resume:
```
%neg = fneg float %n
store float %neg, ptr %neg.spill.addr
; In resume:
%neg.reload = load float, ptr %neg.reload.addr
; ... use %neg.reload
```
After this change, only the operand is spilled and the operation is
rematerialized on each resume, avoiding the frame store:
```
store float %n, ptr %n.spill.addr
; In resume:
%n.reload = load float, ptr %n.reload.addr
%neg = fneg float %n.reload
; ... use %neg
```

The i8 source is zero-extended to XLEN before applying the riscv_brev8

high zero bytes remain zero, so the result can be truncated back to i8.

This enables testing both path separator behaviors (forward slash vs.

The environment variable is checked once and cached in a static variable
for performance.
Also updated relevant tests in SupportTests (Path.cpp and
CommandLineTest.cpp) to dynamically detect the preferred separator style
at runtime instead of relying on the compile-time macro, making them
compatible with the override.

[SLP] Fix assertion "Deleting out-of-tree value" for struct-typed vectorized operands
When an external-use scalar had a struct-typed vectorized operand, OperandIsScalar
incorrectly returned true (because the struct scalar was in ValueToExtUses), causing
the scalar to be cloned into ExternalUsesAsOriginalScalar. The clone used the struct
scalar directly, but struct-typed vectorized scalars are deleted after vectorization
- their external-use handling erases the extractvalue user rather than replacing the

[JumpThreading] Freeze undef/poison select condition in unfoldSelectInstr (#199408)
When unfoldSelectInstr rewrites a select as a conditional branch, it
used SI->getCondition() directly, without freezing it first. A select
with an undef or poison condition does not immediately cause UB,
but branching on undef or poison does, so we need to freeze it.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

[InferAlignment] Propagate alignment information across blocks (#198114)
This patch implements DT-based cross-block alignment propagation. The
algorithm processes the basic blocks in a depth-first traversal of DT.
The stack is emulated to avoid recursive visiting.
IR diff: https://github.com/dtcxzyw/llvm-opt-benchmark-nightly/pull/321.
Most of the improvement is useless, as it makes load/store instructions
overaligned. But several alignment checks are eliminated:

[clang][test] Move offload tools tests to clang/test/OffloadTools (#198434)
Tests for clang-offload-bundler, clang-linker-wrapper,
clang-nvlink-wrapper, and clang-sycl-linker were scattered across
clang/test/Driver/ and clang/test/Tooling/. Neither location was
appropriate: Driver/ is for testing the compiler driver, and Tooling/ is
for testing the LibTooling infrastructure.
Move them to clang/test/OffloadTools/ with one subdirectory per tool,
following the convention used by llvm/test/tools/. The tool-name prefix
is dropped from filenames since the containing directory already
identifies the tool.
The spirv-tools feature/substitution setup is carried over from
Tooling's lit.local.cfg into a new lit.local.cfg in
clang-linker-wrapper/, since the parent clang/test/lit.cfg.py does not
set up that feature. The dead spirv-tools block is removed from
Tooling/lit.local.cfg now that no tests there depend on it.
`clang-linker-wrapper-spirv.cpp` was relying on libomp in the
environment. It is now rewritten to run the `clang-linker-wrapper`
directly rather than going through the driver and added stub symbols
allow avoiding linking against OpenMP runtime libraries.

[mlir][async] Lazily create the coroutine destroy-cleanup block (#199583)
`setupCoroMachinery` previously emitted a `cleanupForDestroy` block
unconditionally, alongside the normal `cleanup` block. That block is
only ever used as the "destroy" successor of an `async.coro.suspend`, so
for coroutines that never suspend (e.g. an `async.func` whose body
contains no `async.await`) it ended up unreachable in the lowered CFG.
Make `cleanupForDestroy` mirror the existing `setError` (and
`setupSetErrorBlock`) pattern and materialize it lazily via a new
`setupCleanupForDestroyBlock` helper, called only from the two places
(`outlineExecuteOp` and the `async.await` lowering) that actually wire
it up. Store the coroutine id on `CoroMachinery` so the helper can
rebuild the block contents without keeping the original `async.coro.id`
op around.
This change is in preparation of adding a new builtin token type. Dead
`async.coro.free` ops are inefficient and cause problems in the lowering
to LLVM.

We can use the pssha instructions. These instructions look at the lower
8-bits of the shift amount and treat positive values as a left shift and
a negative value as a right shift.
Since out of bound shift amounts for SSHLSAT are poison, we can directly
pass the shift amount to the instruction.

llvm: Fix most LLVM_ABI annotations in Transforms (#199042)
This updates most LLVM_ABI annotations in the Transforms headers to
match expected usage:
* All public APIs should be properly annotated.
* Inlined functions should not be annotated.
These changes were done by a script fixing annotations on LLVM public
headers and manually checked.
This effort is tracked in #109483.

In XeGPU layout propagation, when a trivially rematerializable producer

layouts, clone the producer once per required layout so each def retains
a single well-defined layout. This avoids inserting a bridging
xegpu.convert_layout whose WG-to-SG lowering would otherwise force a
costly SLM round-trip to redistribute data across subgroups.

[lld][macho] Restructure thunk generation algorithm (#193367)
Refactor the algorithm that generates thunks for Mach-O. Prior to this
PR, sections were finalized as early as possible while still leaving
enough room (`slopScale * thunkSize`) for new thunks to be created.
There was also additional bookkeeping
(`estimateBranchTargetThresholdVA()`) so that once all sections were
finalized, we could estimate the end of the stubs sections. This avoided
new thunks to stubs sections in some cases.
In this PR, I've restructured the algorithm to avoid eagerly finalizing
sections. Instead, I maintain a `branchesToProcess` queue to hold
branches that could need to use a thunk. I avoid processing this branch
until its target has been finalized, or if finalizing another section
not leave enough room for new thunks (computed using `slopScale`). This
increases the likelihood that a branch will be direct, rather than use a
thunk, as reflected in the test change. Once all sections are finalized,
we can compute an upper bound on the number of thunks that need to be
created. We use this to estimate the end of the stubs section, allowing
us to keep some direct branches.
For testing, I linked a large binary before and after this PR. Results
show a 0.80% reduction in the number of thunks and 6.6% reduction in
number of thunk calls. The change in the duration of the link was
negligible.

During the promotion of a v16bf16 vector setcc with 256 bit sve, a
v16i16 setcc(v16f32) is created, that gets legalized to a v8i16
setcc(v8f32), which trips up an assert in the aarch64 custom lowering to
vector registers. It could be solved elsewhere but this addresses it by
making sure that when the f32 setcc is created, the result type matches
getSetCCResultType.
The mvn+xtn vs xtn+mvn is mostly benign, and should both probably be a
subhn if it can be done without causing regressions.

-----------
[lld][MachO] Preserve __eh_frame ordering during BP section sorting (#191412)
The Balanced Partitioning section orderer collects all live
`ConcatInputSection`s as candidates for content-similarity reordering.
This includes `__eh_frame` CIE and FDE records, which have internal
ordering constraints: each FDE contains a backward-relative 32-bit
offset to its parent CIE, requiring CIEs to precede their FDEs.
When the BP orderer assigns priorities to `__eh_frame` subsections and
`Writer.cpp` sorts by those priorities, FDEs can end up before their
parent CIEs. The resulting CIE-pointer offsets resolve correctly with
32-bit wrapping arithmetic but underflow with 64-bit pointer arithmetic,
causing DWARF consumers (crash reporters, debuggers) to silently lose
unwind data.
## Fix
Have the BP orderer skip the Mach-O `__TEXT,__eh_frame` section
explicitly before collecting candidate subsections, preserving the
existing CIE/FDE order without adding state to `Section`.
This is the only MachO section with this constraint:
- `__unwind_info` is a `SyntheticSection` (not a `ConcatOutputSection`),
so it never enters the BP pipeline
- `__gcc_except_tab` LSDA entries are referenced by absolute offset, so
reordering is safe
- `-order_file` is unaffected because it assigns priorities through
symbol definitions (which live in `__text`, not `__eh_frame`). Only the
BP orderer enumerates sections directly.
## Production impact
Verified on a large iOS application (~218 MB binary, ~34,000 FDEs)
linked with `lld` + `--bp-compression-sort=both`.
### Static analysis of `__eh_frame`
Simulating 64-bit CIE pointer resolution on the output binary across
multiple builds:
| Build | `__eh_frame` layout | FDEs resolved (64-bit) | FDEs failed |
|---|---|---|---|
| lld + BP sort | FDEs first | 15 / 34,257 | **34,242 (99.96%)** |
| lld + fix | CIEs first | 30,558 / 30,558 | **0** |
### Runtime verification
Proxied crash report uploads from a device running both the affected and
fixed binaries:
| | Affected build | Fixed build |
|---|---|---|
| Threads captured | 3 | 24 |
| Total frames | 28 | 135 |
| Background threads | 0-2 | 23 |
The affected build lost ~85% of thread data. The crash reporter could
only unwind the crashed thread (via compact unwind). All background
thread unwind data was silently dropped.
## Reproducer
Minimal test case (ARM64). Requires `--bp-compression-sort=both` to
trigger:
```bash
llvm-mc -filetype=obj -emit-compact-unwind-non-canonical=true \
-triple=arm64-apple-macos11.0 test.s -o test.o
ld64.lld -arch arm64 -platform_version macos 11.0 11.0 \
-syslibroot $(xcrun --show-sdk-path) -lSystem -lc++ \
test.o -o test --bp-compression-sort=both
llvm-objdump --dwarf=frames test
# Without fix: "error: parsing FDE data at 0x0 failed due to missing CIE"
# With fix: CIE records correctly precede their FDEs
```
Standalone reproducer with 64-bit CIE simulation script:
https://gist.github.com/karim-alweheshy/ae28196c4fbb295f81cc793cfbe0c1b7
## Test
The lit test creates multiple functions with `cfi_escape` (forcing DWARF
unwind mode) and different personality functions (producing separate
CIEs), then links with `--bp-compression-sort=both`. Verified on both
x86_64 and arm64.

[ORC] Shutdown the socket FD before closing it in FDSimpleRemoteEPCTransport (#196835)
It is totally possible that when
`FDSimpleRemoteEPCTransport::disconnect` is called,
`FDSimpleRemoteEPCTransport::listenLoop` is still reading on the socket
FD the former is closing. On Linux, closing a socket FD when it is being
read by another thread is an undefined behavior I believe. And on modern
kernels, the reading thread will not be waken up, so `listenLoop` will
be blocked forever and preventing the process from exiting.
This patch fixes this issue by calling `shutdown(2)` on the socket FDs
before closing them.

[flang][OpenMP] Warn that declare simd in an interface body has no effect (#199248)
Follow-up to the crash fix for #192581. A DECLARE SIMD directive may
legally appear in the specification part of an interface body, but it
applies to the external procedure being declared rather than to any
definition in this compilation. Flang does not propagate the directive
to callers, so it has no effect and is silently dropped during lowering.
Detect this in semantics by checking whether the program unit containing
the directive is an interface body (SubprogramDetails::isInterface())
and emit an -Wopenmp-usage warning so the user knows the directive is
ignored.
Updates #192581

[mlir][MemRef] Move FlattenMemRefs to interfaces (#198625)
Use IndexedAccessOpInterface for indexed memory operations and
VectorTransferOpInterface update methods for vector transfers ops. Add
an IndexedMemCopyOpInterface-based flattening pattern for DMA-like
operations.
This gets rid of the hardcoded operation list in the patterns, allowing
dialects like AMDGPU to transparently work with memref flattening.
As a consequence, the specialized vector- and memref-dialect only
constructors that only load a subset of the flattening patterns are
removed.
Also adds a max() method to SaturatedInteger because it was useful for
computing the size of a flat memref.

[AMDGPU] Lay groundwork for stridemark type / addrspace(9) via sgep (#198930)
This commit introduces and documents the `amdgpu.stridemark` target
type, which is used to express when a structured.gep intrinsic is being
used to increment/decrement the index part of a `ptr addrspace(9)` (as
opposed to GEP, which manipulates the offset part)
Future PRs will add inbounds/nusw/nuw support to structured GEP to
enable more efficient code generation and then will implement a lowering
of these structured GEPs to struct.buffer intrinsics.

[lldb] Set SO_NOSIGPIPE on platforms that support it (#198044)
On macOS, I've seen instances where debugserver goes down very quickly
after it starts up (less than 100ms). Normally, LLDB is able to detect
when debugserver goes down and report it without bringing down the
entire debug session. However that's not happening here. My best guess
is that debugserver is going down before LLDB is ready to react to it.
To mitigate this scenario, adopt SO_NOSIGPIPE. Note that this mostly
matters for tools that embed liblldb. The LLDB driver ignores all
SIGPIPEs.

This enables excluding the absolute path to the sysroot from debug info
for reproducible builds. These fields are used by lldb, which also has
fallbacks since it's possible these paths don't exist on the machine
doing the debugging when built remotely anyways.
This was also possible using
`-fdebug-prefix-map=/path/to/Xcode.app=/some/path`
but depending on the environment you might not be able to easily pass
that with the user specific developer directory path.

[SSAF][WPA] Bounds propagation graph is a supergraph of the pointer-flow graph (#198889)
Background: The whole-program UnsafeBufferReachableAnalysis propagates
bounds between pointers. It uses the pointer-flow graph extracted and
linked from translation units.
This commit patches the gap between the semantics of bounds propagation
and pointer-flow: the bounds propagation graph is a super graph of the
pointer-flow graph in that a pointer-flow graph edge `(src, i) -> (dst,
j)` is the projection of a finite set of bounds propagation graph edges
`{(src, i+d) -> (dst, j+d) | 0 <= d < UB}` for a small constant upper
bound UB. See the following example for the idea:
```
void f(int ***p, int **q) {
*p = q;
(**p)[5] = 0;
}
```
There is one edge for the static pointer assignment: '(p, 2) -> (q, 1)'.
In terms of bounds propagation, this assignment implies that if 'p' at
pointer level 2 requires bounds, 'q' at pointer level 1 must also have
them. Furthermore, this relationship propagates to deeper indirection
levels: if 'p' at level 3 requires bounds (due to '(**p)[5]'), so does
'q' at level 2.

[lld][MachO] Fix SIGBUS crash in saveOrHardlinkBuffer (#198381)
This change removes a hardlink in saveOrHardlinkBuffer if the
hardlink already exists.
On Mac, -object_path_lto files are hardlinked to the cache when
possible. If the hardlink fails, the saveOrHardlinkBuffer method
falls back to saveBuffer instead.
saveBuffer() opens the file that is being written to as a
raw_fd_ostream object, which truncates a file when opening if the
file already exists.
Most of the time this is not an issue, however, if the hardlink
fails because it actually already exists, AND the hardlink exists
specifically between the -object_path_lto file and the cache file,
then when the file is opened and truncated, we also accidentally
truncate the file we are trying to read from.
This fixes a recurring issue Chromium saw in buildbots that
occassionally hit the above circumstances to cause the crash.
Chromium bug for reference is crbug.com/40060675.
This test adds a new file with a large-ish array (32KB) to ensure
the file is large enough to be mmap'd during the linking process.
This was necessary to reproduce the crash, as smaller files were
not mmap'd. The SIGBUS crash only occurs when the file is mmap'd
then truncated.

[clang][SemaOpenACC] Reject VLA reduction (#199178)
`GenerateReductionInitRecipeExpr` only handled `ConstantArrayType` when
walking the operand type to build an InitListExpr. A VariableArrayType
`(int arr[i+1])` fell through to the final else branch and tripped
`assert(Ty->isScalarType())`.
Rather than silently accepting VLAs (which have no reasonable lowering.
unlike pointers, there is an expectation of initialized values,but we
cannot statically enumerate elements), reject them outright in
`CheckVarType` with a new diagnostic err_acc_reduction_vla. This is
consistent with the fact that neither codegen nor lowering currently
supports VLA reductions, and other compilers (GCC crashes, NVC++
silently ignores) do not meaningfully handle them either. The fix
upgrades the existing warning path for non-constant arrays in
`CheckVarType` to an error when the clause kind is Reduction, so VLAs
never reach `GenerateReductionInitRecipeExpr`.
Reproducer:
```c
void foo(void) {
int i;
int arr[i + 1];
#pragma acc parallel reduction(& : arr)
while (1) ;
}
```
Fixes #199162

[DSE] Restrict partial-overlap store merging to matching orderings. (#199728)
Partial-overlap store merging folds the later killing store into the
earlier dead store and erases the killing store. That is invalid if the
killing store is volatile or has stronger-than-unordered atomic
ordering, because erasing it drops an observable write. It is also invalid
if the killing and dead stores have different atomic orderings, because
the bytes originally written by the killing store would inherit the dead
store's atomicity after the merge -- silently dropping (or adding)
atomicity for those bytes.
Require both stores to be unordered (i.e. non-volatile with ordering at
most unordered) and to share the same ordering. This preserves the
existing fold for two simple stores or two unordered-atomic stores
(e.g. simple.ll's test43a) while leaving volatile, ordered-atomic, and
atomicity-mismatched cases in place.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

Treat `type(c_devptr), value` arguments in BIND(C) interfaces like
`type(c_ptr), value` by passing the nested raw address value instead of
the outer derived type ABI. This keeps call signatures consistent for
CUDA Fortran generic specifics that share a C binding label and avoids
argument misclassification at the x86_64 register/stack boundary.

[1/3][RegAlloc][LiveRegMatrix] Fix inconsistency in HoistSpillHelper delegates (#197773)
HoistSpillHelper's LiveRangeEdit delegate callbacks did not keep the
LiveRegMatrix consistent when eliminateDeadDefs triggered interval
shrinking and splitting during spill hoisting.
Three issues:
1. No LRE_WillShrinkVirtReg override: when eliminateDeadDefs shrinks a
vreg's interval via shrinkToUses, the matrix was not updated. Add an
override that unassigns the vreg from the matrix and records it in
PendingReassignments for later re-assignment.
2. LRE_DidCloneVirtReg called VRM.assignVirt2Phys without
Matrix->assign: when splitSeparateComponents creates new vregs, the
clones got VRM entries but were never inserted into the matrix. Fix by
consuming PendingReassignments and properly assigning both Old (shrunk)
and New (split) intervals to the matrix.
3. No flush for shrink-without-split: if a vreg was shrunk but not
split, LRE_DidCloneVirtReg was never called to re-assign it. Add a flush
loop at the end of hoistAllSpills to re-assign any remaining pending
vregs.
Also update LRE_CanEraseVirtReg to clear pending entries for erased
vregs.

When include scanning is enabled, the `PassRegistry.def` gets omitted
because it the include scanner does not handle this case. Providing it
via `additional_compiler_inputs` ensures it is included even in that
case.

[SLP] Fix FMA regression in FMA-candidate retry
When tryToVectorize is called with AllowFMACandidates=true, falling
through to tryToVectorizeList vectorizes the fmul operands of an
FMA-candidate fadd without accounting for the lost FMA opportunity.
canConvertToFMA requires those fmuls to have one use, so vectorizing
them always breaks FMA formation. The cost model for tryToVectorizeList
omits the fadd from the tree and compares "2 fmuls vs 1 vfmul", missing
the scalar FMA savings entirely.
Block tryToVectorizeList when AllowFMACandidates=true. TryToReduce is
safe because computeReductionCost accounts for FMA in the scalar
baseline via canConvertToFMA on the fadd user.

[Clang][AArch64] Fix crash with large arguments to MTE built-ins (#197620)
The second argument to `__builtin_arm_irg()` and `__builtin_arm_gmi()`
is expected to be 64-bit. When a wider type is passed, the compiler
still generates a `zext` instruction, leading to a backend error:
```
> cat test.c
unsigned test(void* a, unsigned __int128 m) {
return __builtin_arm_gmi(a, m);
}
> clang -target aarch64 -march=armv9+memtag -S test.c
fatal error: error in backend: Cannot select: ... i64,ch = load<... zext from i128>
```
This is fixed by applying the required implicit conversions to the
argument in Sema.

[AMDGPU] Fix ELF note emission to include null terminator (#199720)
The `AMDGPUTargetELFStreamer::EmitNote()` function claims the note name
includes a null terminator (NameSZ = Name.size() + 1) but only emits the
string bytes via `emitBytes(Name)`, relying on alignment padding to
provide the null byte. Works for most situations but breaks with 8-byte
names where padding lands exactly at the boundary.
Explicitly emit null terminator with `S.emitInt8(0)` after
`emitBytes(Name)`.

[lldb] Fix vtable support on arm64e (#199116)
There were 2 small issues.
1. ValueObjectVTableChild was not fixing the addresses it was pulling
from signed pointers. This broke things like `SBValue::GetLoadAddress`
and identifying the function pointer type from debug info.
2. TestVTableValue.py made a lot of assumptions that did not hold on
arm64e. a. GetValueAsUnsigned will return a raw pointer value. Most of
the time, we needed GetValueAsAddress. b. The test was reading pointers
out of memory without fixing them up. c. The summary for a function
pointer on arm64e includes the load address. This isn't true on other
platforms.

[lldb] New expedited register specfication for unavailable regs (#193894)
When lldb-server/debugserver send a stop packet, they expedite the
vaLues of many of the general purpose registers in the stop packet, so
lldb doesn't need to fetch them separately.
On Darwin systems using an AArch64 M4 or newer SOC with SME, we need to
fetch the streaming vector length (svl) register when in Streaming SVE
Mode to correctly size the registers in lldb. On Darwin systems, when we
are not in SSVE mode, svl is undefined -- it is not included in the
expedited registers. However, lldb will still try to fetch the value, so
we get a register-read packet at every stop on M4 and newer systems,
trying to fetch the value.
This patch adds a new format for the expedited registers. They are
normally a `;` separated series of `{regnum}:{native endian bytes}`.
This allows for `{regnum}:` alone, indicating that the register value
for regnum cannot be fetched at this stop.
It updates debugserver to always add svcr, tpidr2, and svl to the
expedited registers, whether we can fetch them or not.
Most of the changes happen in GDBRemoteRegisterContext. This class
maintains a buffer sized for the register context bytes, and an array of
bool to indicate whether we have fetched the value for a given register
yet or not. If we have fetched the value, we can supply the bytes from
the register context byte array. If it is not yet fetched, we read it.
This PR changes this fetched-or-not bool array to a LazyBool with
eLazyBoolYes meaning we have the bytes for the register value in the
lldb buffer.
eLazyBoolCalculate means we have not yet tried to read the register
value.
eLazyBoolNo means that the register is currently readable.
The meaning of these 3 LazyBool states could be a little confusing as
you read GDBRemoteRegisterContext, so all getting/setting of these is
done through the methods
SetAllRegistersValid()
SetAllRegistersUnfetched()
{Set,Get}RegisterIsValid()
{Set,Get}RegisterIsUnavailable()
{Set,Get}RegisterIsUnfetched()
Whcih I think makes it a little easer to understand. The changes to
GDBRemoteRegisterContext were the trickiest part of this PR, all the
other changes are simple.
Linux et al mostly work on AArch64 systems with SVE + SME, in which case
we have either a vector length or a streaming vector length, at all
times. But the M4 & newer SOCs from Apple don't have any SVE registers
when not in streaming SVE mode, so we have this issue of an extra
register read at all stops, unless in SSVE mode.

[LoopFusion] Do not fuse loops with different guards (#199724)
The testcase that was originally contributed to #193641 exposed a
functional issue in which loop fusion can fuse functions with different
loop guards. There seem to two distinct bugs and each of them alone is
enough to let this happen.
- The condition that checks loop guards are identical, intends to
exclude loops that require peeling. But the condition is not correct and
it allows some loops that do not require peeling to pass.
- The condition that checks two guards are identical implicitly assume
conditions of guard branches are instructions, but this is not
necessarily always correct.
This patch fixes the problem for the loops that do not require peeling.
The issue still exists for loops that require peeling and will be fixed
separately.

This is a follow-up on Jean's comment
https://github.com/llvm/llvm-project/pull/198933#discussion_r3279535746
This patch makes use of the descriptor strides when `fir.array_coor`'s
memref is a `fir.box` that is not a fir.embox result.

[flang] Enabled pulling of rebox into array_coor. (#199161)
This patch enables pulling slicing `fir.rebox` operations
into `fir.array_coor`. This helps preserve information about
the original rank of the array being accessed.
`FIRToMemRef` and later passes may benefit from this.

[AArch64] Fix hasNearbyPairedStore to handle non-inbounds GEPs (#199137)
Problem: `hasNearbyPairedStore` uses
`stripAndAccumulateInBoundsConstantOffsets` to decompose store pointers
into (base, offset) pairs and check whether two stores are 16 bytes
apart. This fails when LSR has rewritten pointer arithmetic into
non-inbounds GEPs because the function refuses to look through them. The
two stores then appear to have different base pointers and the check
returns false. When this happens, `lowerInterleavedStore` proceeds to
emit `ST2` for a pattern that would be more profitable as `zip+stp`,
since the load-store optimizer can pair adjacent stores into `STP` but
cannot merge `ST2` with anything. On a bf16-to-fp32 NEON conversion loop
this causes a regression from 11 to 17 instructions per iteration.
Note: Interleaved stores support was added for RISCV in
https://github.com/llvm/llvm-project/pull/115354. Turning this off
produces the desired STP instructions.
https://godbolt.org/z/1afsjPd3e
Fix: Switch to `stripAndAccumulateConstantOffsets` with
`AllowNonInbounds=true`. The function is a bail-out heuristic doing pure
address arithmetic, so the inbounds semantic guarantee is not needed for
correctness.

[WebAssembly] WASIP3 Library Call Thread Context Support (#175800)
The [WebAssembly Component
Model](https://component-model.bytecodealliance.org/) has added support
for [cooperative
multithreading](https://github.com/WebAssembly/component-model/pull/557).
This has been implemented in the [Wasmtime
engine](https://github.com/bytecodealliance/wasmtime/pull/11751) and is
part of the wider project of [WASI preview
3](https://wasi.dev/roadmap#upcoming-wasi-03-releases), which is
currently tracked
[here](https://github.com/orgs/bytecodealliance/projects/16).
These changes require updating the way that `__stack_pointer` and
`__tls_base` work purely for a new `wasm32-wasip3` target; other targets
will not be touched. Specifically, rather than using a Wasm global for
tracking the stack pointer and TLS base, the new
[`context.get/set`](https://github.com/WebAssembly/component-model/blob/main/design/mvp/CanonicalABI.md#-canon-contextget)
component model builtin functions will be used (the intention being that
runtimes will need to aggressively optimize these calls into single
load/stores). For justification on this choice rather than switching out
the global at context-switch boundaries, see [this
comment](https://github.com/WebAssembly/wasi-libc/issues/691#issuecomment-3716405618)
and [this
comment](https://github.com/WebAssembly/wasi-libc/issues/691#issuecomment-3716916730).
This PR adds support for using library calls instead of globals for
holding the stack pointer and TLS base. When used, this thread context
ABI emits calls to `__wasm_{get,set}_{stack_pointer,tls_base}` when
needed. These functions can then be implemented in `libc`. This is
enabled only for the WASIp3 target.
There is a temporary macro define for `__wasm_libcall_thread_context__`
which can be removed once `wasi-libc` has fully migrated to the new ABI
for the WASIp3 target.

[lit][NFC] remove new-style class opt-ins (#199784)
In Python 3.0 and later it is no longer necessary to explicitly derive
from `object` to opt into "new-style" classes, they are the default.
Since the current minimum Python version is 3.8, this is no longer
required. This patch removes `object` from the base class lists of all
affected classes in lit.

[LV] Add support for partial alias masking with tail folding (#182457)
This patch adds basic support for partial alias masking, which allows
entering the vector loop even when there is aliasing within a single
vector iteration. It does this by clamping the VF to the safe distance
between pointers. This allows the runtime VF to be anywhere from 2 to
the "static" VF.
Conceptually, this transform looks like:
```
// `c` and `b` may alias.
for (int i = 0; i < n; i++) {
c[i] = a[i] + b[i];
}
```
->
```
svbool_t alias_mask = loop.dependence.war.mask(b, c);
int num_active = num_active_lanes(mask);
if (num_active >= 2) {
for (int i = 0; i < n; i += num_active) {
// ... vector loop masked with `alias_mask`
}
}
// ... scalar tail
```
This initial patch has a number of limitations:
- The loop must be tail-folded
* We intend to follow-up with full alias-masking support for loops
without tail-folding
- The mask and transform is only valid for IC = 1
* Some recipes may not handle the "ClampedVF" correctly at IC > 1
* Note: On AArch64, we also only have native alias mask instructions
for IC = 1
- Reverse iteration is not supported
* The mask reversal logic is not correct for the alias mask (or
clamped ALM)
- First order recurrences are not supported
* The `splice.right` is not lowered correctly for clamped VFs
- Reductions are not supported
* The final horizontal reduction needs to set lanes past the
"ClampedVF" to the identity value
- This style of vectorization is not enabled by default/costed
* It can be enabled with `-force-partial-aliasing-vectorization`
* When enabled, alias masking is used instead of the standard diff
checks (when legal to do so)
This PR supersedes #100579 (closes #100579).

Compute GUIDs once and store in metadata (#184065)
This allows us to keep GUIDs consistent across compilation phases which
may change the name or linkage type.
See https://discourse.llvm.org/t/rfc-keep-globalvalue-guids-stable/84801
This is a large change since the addition of metadata breaks many tests.
The test changes are mostly just trivial changes to checks to get them
passing.

Fix the column `0` for the `<total>` row in llvm-mca's `Average Wait times` report. The `total`
row now represents the total dynamic execution count used to normalize the averages,
instead of the per-instruction iteration count. Update the timeline view docs and autogenerated
test expectations accordingly.

[MC] Diagnose unfinished CFI frame from an earlier section (#196775)
Fixes #177852.
The reproducer has two `.cfi_startproc` directives separated by a
`.popsection`. The first is never closed; the second is properly paired
with `.cfi_endproc`. `MCStreamer::finish()` only inspects the last entry
of `DwarfFrameInfos`, so the unfinished earlier frame slips through and
crashes `finishImpl()` when it emits frame data with a null End label.
Use `hasUnfinishedDwarfFrameInfo()` instead, which walks the full
`FrameInfoStack` and catches every unfinished frame.

[compiler-rt][ARM] Add missing SUPERSEDES for optimized FP comparison sources (#199604)
PR #179924 and #179925 added optimized assembly implementations for ARM
double-precision and single-precision FP comparisons (arm/cmpdf2.S,
arm/gedf2.S, arm/unorddf2.S, arm/cmpsf2.S, arm/gesf2.S, arm/unordsf2.S)
but only added SUPERSEDES annotations for the thumb1 variants. The arm
variants were missing these annotations, causing both the generic and
optimized implementations to be included in libclang_rt.builtins.a.
For double-precision, the archive contains:
- comparedf2.c.obj (pos 28): defines __unorddf2, __aeabi_dcmpun, ...
- divdc3.c.obj (pos 32): defines __divdc3; refs __aeabi_dcmpun
- unorddf2.S.obj (pos 126): defines __unorddf2, __aeabi_dcmpun
- aeabi_dcmp.S.obj (pos 158): defines __aeabi_dcmpeq; refs __eqdf2
When linking divdc3_test.c, the linker loads divdc3.c.obj which
introduces __aeabi_dcmpun as undefined. BFD-like linkers (GNU ld, ELD)
continue scanning forward and resolve __aeabi_dcmpun from unorddf2.S.obj
(pos 126). Later, aeabi_dcmp.S.obj introduces __eqdf2 as undefined,
which is resolved by comparedf2.c.obj (pos 28) on the next pass. Since
both comparedf2.c.obj and unorddf2.S.obj define __unorddf2, the linker
reports a duplicate symbol error.
lld does not encounter this because of the difference in the way it
resolves symbol references. This causes comparedf2.c.obj (pos 28) to be
selected first for __aeabi_dcmpun, making unorddf2.S.obj unnecessary.
The same pattern exists for single-precision where arm/comparesf2.S and
arm/unordsf2.S both define __unordsf2 and __aeabi_fcmpun.
The fix adds SUPERSEDES annotations so that the generic implementations
(comparedf2.c for double-precision and arm/comparesf2.S for single-
precision) are removed from the source list when the optimized assembly
replacements are present. The assembly files together provide all
symbols that the generic implementations define.
The surrounding code was reviewed, and this PR was developed with the
assistance of AI.

[lit] Move maxIndividualTestTime from global to test suite config (#198192)
Simplify LitConfig initialization and setter to allow None values.
TestingConfig.maxIndividualTestTime is initialized to 0 (or resolved to
0 if None) strictly during initialization.
This fixes an issue where the aggressive BOLT timeout of 60s (previously
set globally on lit_config) was leaking and affecting libc++ tests. By
moving the timeout configuration from the global lit_config to the
individual test suite config, we ensure that timeouts are isolated and
respect suite-local settings without leaking.

[LifetimeSafety] Add details for `-Wlifetime-safety-return-stack-addr` diagnostic (#199432)
Most of the diagnostic's wording was taken from `-Wreturn-stack-address`
with exceptions such as:
- We do not special-case `[[clang::musttail]]`
- We do not special-case `CompoundLiteralExpr` as it is mostly a C
thing.
This patch does not add any new tests, it only updates already existing
test warnings to follow the new wording.

[llvm-debuginfo-analyzer] Add support for LLVM IR format. (#135440)
llvm-debuginfo-analyzer is a command line tool that processes debug
info contained in a binary file and produces a debug information
format agnostic “Logical View”, which is a high-level semantic
representation of the debug info, independent of the low-level format.
Add support for the LLVM IR format and be able to generate logical
views. Both textual representation (.ll) and bitcode (.bc) formats
are supported.

Instead provide both variants: a const accessor returning a const ref
and non-const one returning a mutable ref.

which doesn't help with figuring out what's going wrong.

Add builtin to clear padding bytes. This is the pre-work to implement
`std::atomic::compare_exchange_[weak/strong]` that ignores padding bits.
PR draft here: https://github.com/llvm/llvm-project/pull/76180
This PR picked up this patch from 3 years ago
https://reviews.llvm.org/D87974
The above patch no longer works as things changed quite a lot. I've made
some changes on top of the above patch:
it handles:
- struct
- builtin types with paddings (like `long double` and types with
`__attribute__((ext_vector_type(N)))`
- _Complex long double
- constant array
- union
- bit field
- types with virtual functions
- types with virtual bases

[AArch64][TTI][EarlyCSE] Add support for ld1xN and st1xN intrinsics (#198765)
Handle ld1x2, ld1x3, ld1x4, st1x2, st1x3, st1x4 in:
- AArch64TTIImpl::getTgtMemIntrinsic
- AArch64TTIImpl::getOrCreateResultFromMemIntrinsic
This enables EarlyCSE to optimize these NEON load/store intrinsics.
To test the changes, a new testcase (intrinsics-1xN.ll) derived from
llvm/test/Transforms/EarlyCSE/AArch64/intrinsics.ll is added.

[SelectionDAGBuilder] Replace asserts inside LLVM_DEBUG (#199748)
These assert were inside an LLVM_DEBUG macro, meaning they were very
rarely if ever tested. The second "LowerFormalArguments emitted a value
with the wrong type!" assert would fire in a number of tests so has been
removed. The other was replaced with an all_of assert.
Noticed when looking at #198107 / #199412.

[MLIR][AMDGPU] Add permlane16.var and permlanex16.var intrinsic ops (#199501)
## Summary
Add ROCDL and AMDGPU dialect support for the GFX12+ variable-selector
permlane intrinsics (`v_permlane16_var_b32` / `v_permlanex16_var_b32`).
Unlike the existing fixed-selector `permlane16`/`permlanex16` ops where
source-lane indices come from SGPR immediates, the "var" variants take
per-lane source-lane indices from a VGPR, enabling arbitrary per-lane
intra-row and cross-row permutations within a wave32 subgroup.
### ROCDL dialect
- `ROCDL_Permlane16VarOp` → `llvm.amdgcn.permlane16.var`
- `ROCDL_PermlaneX16VarOp` → `llvm.amdgcn.permlanex16.var`
- Both take `(old, src0, src1, fi, boundControl)` with `fi` and
`boundControl` as immediate i1 attrs
### AMDGPU dialect
- `AMDGPU_PermlaneVarOp` — high-level wrapper supporting arbitrary
int/float/vector types
- `cross` attribute selects between intra-row (`permlane16.var`) and
cross-row (`permlanex16.var`)
- Lowering uses `LLVM::decomposeValue`/`composeValue` to automatically
repack types (f16, i8, vectors, etc.) into i32 register slots
### Tests
- ROCDL roundtrip (parser/printer) tests
- ROCDL → LLVM IR translation tests
- AMDGPU → ROCDL lowering tests covering i32, f32, f16, vector<4xf16>,
cross variants, and fi/bound_ctrl attributes

[clangd] Prefer .hpp files over .h with header source switch (#198152)
Previously, The "Switch Between Source/Header" action picked `.h` over
`.hpp` when both files existed next to a `.cpp` file, because `.h` is
listed first in the header-extension list.
This patch reorders `HeaderExtensions` and `SourceExtensions` so the
`C++`-flavored extensions come before `.h` and `.c`. `C++`-flavor of
file is preffered since (at least in my opinion) more people using
`clangd` for `C++` than `C` with `.hpp` ext so switching from `.cpp`
should go into `.hpp`, not `.h`.
This brings an edje case that when swithing from `.c` it will go into
`.hpp` instead of `.h`, but I think this situation is more rare than
having `.cpp` with `.hpp` and `.h` combination since `.h` headers can be
used as `extern "C"` wrapper of cpp library.

Extract the VF-independent VPlan1 setup pipeline (header phis,
simplification, early-exit handling, middle check, loop regions, tail
folding, mask introduction) into a new helper tryToBuildVPlan1().
Construct the initial Vlan1 once, and pass to repeated buildVPlans
calls.
Note that this means we need to move collectInLoopReductions up. We not
may construct VPlan1 on code paths where we did not before, because we
failed UserVF validation/selection, but I think that should be fine as
this makes the overall code simpler and the UserVF code paths are for
testing.

from the demanded insert instructions. Move the scalarization cost adjustment
to after InMask is computed so ForPoisonSrc reflects the actual base vector

[DebugInfo] Introduce DW_AT_LLVM_language_dialect (#194898)
This PR introduces an LLVM vendor DWARF attribute on compile units that
carries an optional target-specific language dialect enumerator,
distinct from DW_LANG_*. The intent of this addition is to allow a DWARF
consumer to differentiate the source programming language from the
programming model (e.g., CUDA/SIMT, Tile, etc.). This concept could also
be used to differentiate OpenMP, or other parallel models, from host
language.
As older languages adopt newer programming models, there's no need to
introduce a new language enumerator to encode that representation;
rather, the model can be encoded as a dialect and treated as a
refinement to the source language being compiled. For ease of
extensibility, we've decided to represent the value of this new dialect
attribute as a string.
Code/comments/description were developed with LLM assistance.

Add Pre-Optimization FunctionPropertiesStatistics Pass - All Properties (#199293)
Adding a PreOptimization pass for function properties that provides the
statistics preoptimization without leading to timeouts (also thanks to
https://github.com/llvm/llvm-project/pull/198940 and internal changes on the faulty target)
First iteration led to timeouts so it got reverted
https://github.com/llvm/llvm-project/pull/188837
(UPDATE) Through a flame graph proved that changes in
https://github.com/llvm/llvm-project/pull/198940 , mainly the change
inside the loop, was the one responsible for the timeout. Flame graph spent a majority of the time on updateForBB, and it's the only part there could be a blocker. Furthermore, target was fixed internally.
Previous iteration tried to get only some of the statistics, but managed
to prove locally that it's not necessary to distinguish between them
https://github.com/llvm/llvm-project/pull/199073 since the changes mentioned previously were good enough

[PowerPC] Drop invalid range metadata when lowering i64 load to fp in INT_TO_FP (#198705)
When lowering an i64 load in LowerINT_TO_FP, we were forwarding the
original !range metadata to a new f64 load. This is invalid because the
metadata no longer matches the value type/semantics, and can trigger
assertions when lowering i64 to fp (double or float) conversions.
This patch fixes this by passing a nullptr for the Ranges operand when
calling getLoad() and adds extra test cases to cover signed/unsigned i64
to f32/f64 conversions and to ensure they do not assert when the !range
metadata is present.
The assertion this patch attempts to fix is:
```
Assertion failed: (!MMO->getRanges() || (mdconst::extract<ConstantInt>(MMO->getRanges()->getOperand(0)) ->getBitWidth() == MemVT.getScalarSizeInBits() && MemVT.isInteger())) && "Range metadata and load type must match!"
```
This assert was originally seen when building Rust on AIX.

Reapply "[clang][ssaf][NFC] Rework how the Force linker anchors are defined and used" (#194693)
This reverts commit 582958c4337f539e650096c0257a322315298e1a.
Drop "const" from these anchor variables - like they are in clang-tidy
Turns out, MSVC likely doesn't conform with the C++ standard and makes
`const volatile` global variables have *internal* linkage - while they
should have *external* linkage.
https://eel.is/c++draft/basic.link#3.2
```
(3) The name of an entity that belongs to a namespace scope has internal linkage if it is the name of
(3.1) a variable, variable template, function, or function template that is explicitly declared static; or
(3.2) a non-template variable of non-volatile const-qualified type, unless
(3.2.1) it is declared in the purview of a module interface unit (outside the private-module-fragment, if any) or module partition, or
(3.2.2) it is explicitly declared extern, or
(3.2.3) it is inline, or
(3.2.4) it was previously declared and the prior declaration did not have internal linkage; or
```
Consequently, `const volatile` globals should NOT have *internal*
linkage, because `volatile` variables are exempt by (3.2).

[lld][ELF] Exclude SHT_NOBITS sections from LMA overlap checks (#196423)
In embedded applications it's sometimes useful to load a section at the
same virtual address as the .bss section. For example, one possible use
case is for temporary code/data that is only needed for a short time
when the program is starting up:
REGIONS {
RAM : ORIGIN = 0x100000, LENGTH = 1M
INIT : ORIGIN = 0x200000, LENGTH = 1M
}
.text { *(.text); } > RAM
.bss (NOLOAD) : { *(.bss); } > RAM
.init : AT(LOADADDR(.bss)) { *(.init); } > INIT
The .init section gets placed in the file immediately after the .text
section. At startup the .init section contents are copied to the INIT
region before zeroing .bss. Once the .init section is no longer needed
its memory can be reused, eg. as heap memory.
Currently, lld does not support this and prints an error because the
LMAs of .bss and .init overlap. There are two workarounds:
1. Use --no-check-sections to disable all overlap checks, but this also
disables VMA and file offset checks, which might not be desired.
2. Assign a fake LMA to the .bss section, which doesn't overlap with the
LMA of any other section. However, this is not very intuitive and
affects the generated program headers (because a second Phdr is needed
now that .bss has a unique p_paddr), which might not be acceptable.
These ugly workarounds can be avoided by ignoring LMA overlaps involving
SHT_NOBITS sections. This is also what binutils does, which is why the
example above works under GNU ld.

wait for "relevant" outstanding operations to complete. With the new
memory model, it is possible to disable the cache write-back using
"non-av". This patch cleanly separates the existing implementation so
that the write-backs can be selectively applied after checking for
non-av semantics.

[AMDGPU] Fix ShiftAmt32Imm to use unsigned comparison (#199052)
ShiftAmt32Imm used a signed 'Imm < 32' predicate, which incorrectly
matched negative immediates such as -1. The scalar fshr fast path:
def : GCNPat<(UniformTernaryFrag<fshr> i32:$src0, i32:$src1,
(i32 ShiftAmt32Imm:$src2)),
(i32 (EXTRACT_SUBREG (S_LSHR_B64 ..., $src2), sub0))>;
When fshl(scalar, X, Z) is lowered via expandFunnelShift for any
constant Z in [0, 31], the generic code converts it to fshr(..., ~Z) or
fshr(..., -Z), producing a negative shift amount. Because all such
values satisfy Imm < 32 in a signed comparison, ShiftAmt32Imm matched
and the pattern passed the negative immediate directly to S_LSHR_B64
without the S_AND_B32 masking. S_LSHR_B64 then shifted by the wrong
amount, producing an incorrect result.
Fix by changing the predicate to an unsigned comparison so that only
values in [0, 31] match, and negative values fall through to the general
pattern which correctly applies S_AND_B32 before S_LSHR_B64.
Fixes miscompilations of scalar fshl with any constant shift amount at
-O0 on AMDGPU targets, covering both fshl(scalar, const, Z) and
fshl(scalar, scalar, Z) for all Z in [0, 31].

[LLVM] Add per-target runtime directory to rpath (#199755)
Summary:
This simply adds the LLVM_DEFAULT_TARGET_TRIPLE to the LLVM build's
rpath if present. This keeps things hermetic for the library (offload)
that depends on it.
The reason this is required is because `llvm-gpu-loader` calls
`DynamicLibrary` on the Offload runtime. However, in a shared library
build the actual call is in libLLVMSupport.so, which does not have this
RPath, so `dlopen` delegates to that which does not know how to find it.
The only options to fix this are to use `dlopen` directly in the loader,
or add the rpath to the LLVM binaries.
I think this makes sense for LLVM, because the target-specific directory
can contain LLVM related libraries.

This was introduced in #194924 to limit code-size growth from runtime
unrolling, but PartialThreshold also gates compile-time partial
unrolling of constant-trip-count loops. This change will make the
PartialThreshold back to the default value for both compile-time partial
unrolling and runtime partial unrolling.
Benchmarked across CK, llama.cpp, and xpu-perf — no performance impact
from restoring the default.

[win][x64] Updated `llvm-objdump` and `llvm-readobj` to be able to dump Windows x64 Unwind v3 information. (#199120)
Public docs:
<https://learn.microsoft.com/en-us/cpp/build/x64-unwind-information-v3?view=msvc-170>
The change adds Windows x64 unwind v3 info decoding and printing support
in LLVM, including new data structures, enums, and decoding functions to
handle the different WOD opcodes and epilog descriptors. It also updates
the dumping utilities (llvm-readobj and llvm-objdump) to correctly
interpret v3 unwind info.

[Flang][OpenMP] Support declare reduction without initializer (#196211)
For declare reduction without an explicit initializer clause, the init
callback now handles initialization inline rather than relying on the
_FortranAInitialize runtime call, which is available on the device
runtime but has known issues on GPU targets.
The initialization logic first checks whether an initializer clause is
present. If one is provided, it is used directly. Otherwise, for derived
types, the code checks whether the type has default component
initialization. If it does, each component is initialized inline:
components with explicit default values use those values, components
that are themselves derived types with defaults are recursively
initialized, and components without any default are zero-initialized.
Derived types with allocatable components that require runtime
initialization are guarded by a TODO.

[mlir][SliceAnalysis] Fix visited set to avoid infinite recursion (#200008)
Fixes #139694, which introduced use-def cycle detection during slice
analysis, but some cycles were still not detected, potentially leading
to infinite recursion.
This PR fixes the handling of the visited set, which tracks the current
DFS path during recursion. Previously, the set could fail to detect
double cycles because entries were erased even when no recursive call
was made. The insert/erase operations are now only performed when
recursion actually occurs, ensuring that cycle detection correctly
reflects the active DFS path.

Since debugger's output is not I/O intensive, there is no risk of

Reapply "[clang] Use FileError in FileManager::getFileRef, getDirectoryRef" (#199759)
Most callers are unchanged, since they either ignore the specific error
or have their own formatting of the error that includes both the path
and the errorToErrorCode-unwrapped value. However, for clients that just
forward the error it's helpful to ensure we do not lose track of the
filename that the error is associated with, so use FileError.
To reduce the overhead of using FileError, keep it only in the public
getFileRef and getDirectoryRef themselves, and use ErrorOr in the
implementation. For callers of getOptional* this should avoid
allocations for errors entirely, and for callers of getFileRef and
getDirectoryRef it makes the error allocation inlinable, which may (in
theory, not tested) let us optimize it away if the Error is immediately
unwrapped back to an error code, for example.
Incidentally clean up some callers to use getOptionalFileRef where they
throw away the error immediately.

[AMDGPU] Use shorter form for i16 operands (#198005)
For 16-bit operands an inline constant is zero extended
which in particular allows to use FP constants. These
will have 16 bits of zeroes in the high half and FP16
value in the low 16 bits.
The patch changes semantics of the FP literal argument
used in i16 context in the asm parser to fp16.

[CIR] Handle the 'before case' block of a switch statement. (#199752)
Before this patch, we would fail any time there was a block with
entry/exit (in this case, one with successors thanks to a label) with a
verification error. This patch adds special handling for that first
block.
This patch DOES choose to not trim them however. Unless there is a label
inside of the block, there isn't any way to get there, and it is dead
code. I've opted to NOT do that optimization, as I suspect that might be
valuable to future passes/something we may wish to warn about in some
sort of CFG analysis.
Additionally, there is some minor changes to FlattenCFG, first to make
sure we skip the switch ONLY if it is truly empty, and second to make
sure we transform any 'break' in the pre-case region.

[clang][lit] Add option to skip clang-repl checks (#199255)
Whenever lit or llvm-lit is invoked to run clang tests, clang-repl is
run at least once to check for host jit capabilities, and possibly
several more times to probe related capabilities. This adds a noticeable
delay before testing starts, especially for debug builds.
This change adds a lit parameter (clang_skip_clang_repl_checks) and an
environment variable check (CLANG_LIT_SKIP_CLANG_REPL_CHECKS) to allow
the clang-repl probes to be skipped. When this option is used, any tests
that rely on jit execution will be reported as unsupported.
This option is intended only to allow quicker targeted testing during
development. It should not be used for comprehensive verification before
submitting a patch.
On my local test system, executing `ninja check-clang-cir-codegen` with
a previously completed debug build took 18 seconds to run 354 tests with
this option and 53 seconds without it. This is the sort of use case I am
targeting -- lit test runs when the clang-repl overhead will constitute
a significant portion of the total time to execute the tests.

[CIR] Handle throwing an exception from a cleanup scope (#199121)
The CIR FlattenCFG pass had been ignoring any ThrowOp that occurred
inside a cleanup scope or try operation, which led to the thrown
exception not triggering local cleanups and bypassing local catch
handlers.
This change introduces a new CIR operation, TryThrowOp, which is
analagous to the existing TryCallOp. The TryThrowOp (as well as the
ThrowOp) will eventually be lowered to a function call, but which
function gets called is a target-dependent detail, so we need an
abstract operation before EHABI lowering.
The Flatten CFG pass replaces any ThrowOp inside a cleanup scope or try
operation with a TryThrowOp that has an unreachable normal destination
and unwinds to the appropriate cleanup or catch dispatch block.

[CUDA][HIP] Defer device diagnostics in implicit H+D explicit instantiations (#197214)
When clang explicitly instantiates a class template, it must emit
device-side
bodies for the implicit `__host__ __device__` members so the vtable and
instantiation symbols resolve. Some of those members chain into
host-only
calls (for example libstdc++ destructors that eventually call ::operator
delete). If no device code actually uses the class, the user still sees
errors about calling a `__host__` function from device code, even though
they
wrote no device code that touches it. Overload ambiguity in the same
context
behaves the same way.
This patch defers device-side errors in implicit `__host__ __device__`
functions reached only via an explicit template instantiation. At the
end of
the translation unit, clang checks whether a real device caller exists.
If
one does, the deferred errors are surfaced with the usual call-stack
notes.
If not, the diagnostics are dropped and the function gets a trap body,
so the
vtable and instantiation symbols stay well-formed and the failure only
fires
if device code ever calls the function. This works without
-fgpu-defer-diag.

[llvm-profgen] Fix assertion condition for the top-level probes address range checks (#198674)
Top-level functions may contains multiple disjoint address ranges, and
the pseudo probes may not be stored as sorted. The original assertion
check is problematic because the first pseudo probe may not necessarily
falls into the current function range even though they are both part of
the same function.
Update the assertion condition so that we won't hit the assertion
failure as long as there one pseudo probe falls in the checked function
range.

[AMDGPU] Implement CFI for CSR spills (#183150)
Introduce new SPILL pseudos to allow CFI to be generated for only CSR
spills, and to make ISA-instruction-level accurate information.
Other targets either generate slightly incorrect information or rely on
conventions for how spills are placed within the entry block. The
approach in this change produces larger unwind tables, with the
increased size being spent on additional DW_CFA_advance_location
instructions needed to describe the unwinding accurately.

For read-only MemoryBuffer_MMap, advise the kernel that access pattern

on *NIX. This function should not be called on a writable buffer.
The implementation follows existing pattern in
`mapped_file_region::dontNeedImpl()` and
`mapped_file_region::willNeedImpl()`.

Reland: [lit] Move maxIndividualTestTime from global to test suite config (#199996)
Simplify LitConfig initialization and setter to allow None values.
TestingConfig.maxIndividualTestTime is initialized to 0 (or resolved to
0 if None) strictly during initialization.
This fixes an issue where the aggressive BOLT timeout of 60s (previously
set globally on lit_config) was leaking and affecting libc++ tests. By
moving the timeout configuration from the global lit_config to the
individual test suite config, we ensure that timeouts are isolated and
respect suite-local settings without leaking.

[alpha.webkit.UnretainedCallArgsChecker] Emit a warning for a non-const RetainPtr member (#184243)
This PR fixes a bug in UnretainedCallArgsChecker that it wouldn't emit a
warning when calling a function with the return value of a getter of a
RetainPtr non-const member variable even if such a member variable could
be mutated during such a function call.
The bug caused by tryToFindPtrOrigin treating any call of a getter on a
smart pointer member variable as safe. Fixed the bug by limiting this to
only when the variable is a local variable or a function parameter.
In addition, this PR fixes a bug in WebKit checkers that it would
erroneously emit a warning when calling a getter on a const RetainPtr
member variable beacuse isOwnerPtr was returning false for RetainPtr.
This false negative was previously masked / hidden by the false positive
fixed in this PR.

[SeparateConstOffsetFromGEP] Set `inbounds` correctly. (#199304)
swapGEPOperand reorders the GEPs (ptr+off)+const into (ptr+const)+off.
When it does so, it needs to determine if the inner GEP is inbounds.
Previously the way it did this was to call
stripAndAccumulateInBoundsConstantOffsets on (ptr+const), and then check
if this offset was indeed in-bounds.
However, this GEP was not necessarily marked as `inbounds` itself. If it
was not, stripAndAccumulateInBoundsConstantOffsets would return 0 for
the offset (instead of `const`), in which case we'd check if
`0 < [obj width]`, which is trivially true, and then incorrectly mark
the GEP as inbounds.

[lldb] Keep addr for Memory Modules separate (#199810)
This change is to make DataFileCache symbol table caching work with
memory-read binary modules.
When we read a Module out of memory, we keep the address of the module
in Module's m_object_name field as a string. This is normally the name
of a file in a ranlib/static library/.a archive like the "main.o" in
"foo.a(main.o)". The address is most often seen in the "image list"
output, and is the only easy way to distinguish in that output which
binaries were read out of memory, versus found on local disk. The "name"
of the Module ends up being the combination of the FileSpec plus this
m_object_name.
Reading a binary out of memory is expensive, primarily because of
reading the symbol table. The DataFileCache feature that Greg introduced
five years ago can cache the Symbol Table for a binary locally, and when
we see the same binary loaded again in a future debug session/lldb
session, we can skip parsing the symbol table (or in the case of Memory
Module, reading it from memory).
Unfortunately because the "name" of the Module is the combination of the
FileSpec PLUS the address, if this is a system where binaries can load
at different addresses, we may not be able to use the DataFileCache for
a memory module. The address should not be part of the name for this.
In Module, I created a new optional ivar to track the memory module
address, if this is one, instead of putting the string representation in
m_object_name. In all places (except the DataFileCache name
construction), I append the address to the name just like we do with
m_object_name.
There were a few logging points that were manually constructing the name
when a method would do it for them already; I changed them to call the
method instead.
Probably the least clean part is in CommandObjectTarget (the image list
output), we add the ObjectName to the FileSpec here as well. For now,
instead of trying to leverage one of the methods in Module that combine
them already, I changed it to use the same change.
I used a std::optional for this address instead of the
LLDB_INVALID_ADDRESS convention because it was a lot cleaner to read, I
thought, even if it is different than most often used in the codebase.
Open to using the older coding style if other people think consistency
is more important.

I was reading through Greg Clayton's DataFileCache PR and fixed a few
small typeos as I went along.
I also had a little trouble understanding the two types of hashes that
are calculated for a file, at first, and I tried to write comments for
the relevant methods (in Module, ObjectFile, and DataFileCache) to be
more explicit about their role and the role of the other hashes that are
calculated. It may be more detail than necessary, but it would have been
helpful for me while reading this through.

[flang][FIRToMemRef] fix stride calculation for complex lowering (#200035)
**Summary**
When `fir.array_coor` targets a projected slice of a complex array (path
0 = real, 1 = imag), FIRToMemRef must not treat the result as a dense
memref.
**Bug:** The pass stopped after fir.convert to `memref<…×complex>` (or
static-shape fast path) and used default/dense strides. Loads/stores
then stepped by sizeof(complex) instead of sizeof(re)/sizeof(im).
**Fix:** For constant `%re/%im` on `complex<T>` storage:
`fir.convert` storage to `memref<…×2×T>` and index the component (0 or
1).
Read layout from `fir.box_dims` on the box (even if the memref shape is
static).
Set each memref stride to `box_dims_byte_stride / sizeof(T)`.

%merge1 = or disjoint <vscale x 8 x i32> %high0, %high1
```
is really just doing `deinterleave2` but on `<vscale x 32 x i16>`. That
is, the same total vector size but with half the element width. So we
can turn it into:
```
%narrow.v = bitcast <vscale x 16 x i32> %v to <vscale x 32 x i16>
%d = llvm.vector.deinterleave2 <vscale x 32 x i16> %narrow.v
%f0 = extractvalue { <vscale x 16 x i16>, <vscale x 16 x i16> } %d, 0
%f1 = extractvalue { <vscale x 16 x i16>, <vscale x 16 x i16> } %d, 1
%merge0 = bitcast <vscale x 16 x i16> %f0 to <vscale x 8 x i32>
%merge1 = bitcast <vscale x 16 x i16> %f1 to <vscale x 8 x i32>
```
I put this in VectorCombine because I'm worried that the newly created
bitcast might be expensive for some targets, hence a profitability check
before committing the transformation.

[lldb][Darwin] Read Mach-O binaries out of memory more efficiently (#200072)
When lldb needs to read a Mach-O binary out of memory, it first reads
512 bytes to get the mach header, which includes the size of the load
commands, and then does a second read to get the mach header and load
commands.
I am changing the initial read to get 3192 bytes, which will include the
full load commands for most binaries.
In April I changed debugserver to return the correct size of the mach
header and load commands in a `sizeof_mh_and_loadcmds` key. If this
number is provided, refine the amount we read to this size.
This reduces the number of memory read packets we issue from 2 to 1 for
a memory module, outside of packets that may be needed to get the symbol
table.

[gsymutil] Disable readahead in `GsymReader::openFile()` (#199230)
`GsymReader::lookup()` has random access pattern (i.e. binary search an
address, then spot-load/parse info from rest of the GSYM data).
Readahead strategies in kernels (which was enabled by default) don't
necessarily improve (and may degrade) performance. This patch disables
readahead.
In a production system, similar change has seen 5% improvement on IOPS
and data reads. An offline performance test on a Linux machine shows
similar results - it reduces 14.3% total data read, 3.5% CPU%, and 2.9%
wall time (while adding 9.4% page faults). The reduction of total data
read and CPU % may help the performance of a heavily-loaded production
system.

```
The test is performed by doing 100 cold runs, where each run first
purges kernel page cache, then opens/mmaps a 3.8 GB GSYM file, and then
looks up 3 addresses at the beginning/middle/end of the address list.
See [test
script](https://gist.github.com/royitaqi/c06c733cccfbf747d63750b06db77b4a).
The pre-existing hidden option `llvm-gsymutil --benchmark-reader` is
extended to take optional `=<start>,<stride>` to make performance
testing easier.

[PGO][AMDGPU] Add basic HIP offload PGO support (#177665)
Provide the minimum HIP/offload path for device profile collection and
merge on HIP before layering profile-format and uniformity-specific
changes separately.
This adds the ROCm collection runtime, hooks device collection into the
host write-file path, lowers AMDGPU instrumentation to
__llvm_profile_instrument_gpu with regular counters, and disables GPU
indirect-call value profiling.

-----------
[coro] Use C calling convention for C++20 coroutines (#198943)
Change the calling convention for resume / destroy functions of C++
coroutines from `fastcc` to the C calling convention.
The resume / destroy functions are exposed as part of the coroutine ABI
and must be compatible with other compilers and other versions of LLVM.
fastcc is an LLVM-internal, unstable calling convention, though.
In practice, fastcc and the C calling convention are in sync for `void
func(void*)` function signatures on almost all platforms. Therefore, I
think we can still do this change without widespread ABI breakage.
`fastcc` and `ccc` do differ for i686 (x86-32), MIPS O32, PowerPC64
ELFv1 and Lanai. Afaik, those are all legacy ABIs and a recent feature
like C++20 coroutines is unlikely to be used by projects still targeting
legacy ABIs.
Historical context: I tried to figure out why `fastcc` was used. It is
around since the original commit f93082e71a94 from 2016, predating the
cross-vendor coroutine ABI work. I could not find any discussion of
whether this should use `fastcc` on the review or on the mailing list.
As a side-effect, this also fixes #91123.

test(llvm-symbolizer): fix Wasm layering violation by using YAML (#200080)
Avoid using wasm-ld in LLVM tests by prebuilding the test binary
as a YAML file and using yaml2obj at test time.
This matches the approach taken in
4bce216e6b550c770f2e536422c3d95333f65ba3.
Because yaml2obj always uses 5-byte LEBs, the CODE section offset
shifted from 0x37 to 0x4b, so the file offsets passed to llvm-symbolizer
were updated accordingly.

This fixes failure in libc tests which checks the exact encoding

Shorter encodings were created here:

[AMDGPU] Use shorter form for i16 operands (#198005)
For 16-bit operands an inline constant is zero extended
which in particular allows to use FP constants. These
will have 16 bits of zeroes in the high half and FP16
value in the low 16 bits.
The patch changes semantics of the FP literal argument
used in i16 context in the asm parser to fp16.
Apparently this breaks some libc tests with bf16. I do not know
why, these were not supposed to be affected. Reverting for now.

merge for copy pairs even when the first copy was not an `a0/a1-based`
CM candidate.
Fix by only running `findMatchingInst` when the current copy is a valid
CM candidate.

ExpandAMDGPUPredicateBuiltIn synthesized an IntegerLiteral typed
_Bool/bool — a shape no other producer creates, and one that
StmtPrinter::VisitIntegerLiteral has no case for. -ast-print on the

Emit the canonical boolean literal instead:

In the C case this matches what <stdbool.h>'s true/false macros expand

[PGO][HIP] Stop pulling ROCm.o into every PGO host link (#200101)
PR #177665 added an unconditional `extern` reference to
`__llvm_profile_hip_collect_device_data` from `InstrProfilingFile.c`,
which forces `InstrProfilingPlatformROCm.o` (and its sanitizer_common /
interception dependencies) out of `libclang_rt.profile.a` in every PGO
binary. That breaks bots without `-lpthread` and races dlsym/PLT state
in non-HIP programs via the interceptor constructor.
Fix:
- Declare the hook `COMPILER_RT_WEAK` and gate the call on its address.
No `COMPILER_RT_VISIBILITY`: a hidden weak-undef function would be
non-preemptible and the address test would fold to true.
- Gate `installHipModuleInterceptors` on `dlsym(hipModuleLoad)` so the
constructor is a no-op if `ROCm.o` is still pulled in.
Fixes:
- https://lab.llvm.org/buildbot/#/builders/66/builds/31311
- https://lab.llvm.org/buildbot/#/builders/174/builds/36180
Verified:
- `check-profile` 134/134 pass.
- `nm` on a non-HIP `clang -fprofile-generate` binary: zero
`installHip`/`ROCm`/`sanitizer`/`hip_collect` symbols.
- HIP offload PGO end-to-end on gfx1101 (compile → run → `llvm-profdata
merge` → `llvm-cov`) still works; interceptor installs, device profile
collected via shared API.

[LoopFusion] reject unsafe scalar flow dependences (#195895)
`loop-fusion` treats any loop-invariant scalar non-anti dependence as
safe to fuse. In the linked issue, it incorrectly allows scalar flow
dependences where the first loop writes a loop-invariant location and
the second loop later reads that same location. Fusion interleaves the
producer and consumer and this changes the value observed by the second
loop.
Example C source would look like:
```C
for (int i = 0; i < N; i++) {
ptr[0] = i;
}
for (int j = 0; j < N; j++) {
out[j] = ptr[0];
}
=>
for (int i = 0; i < N; i++) {
ptr[0] = i;
out[i] = ptr[0];
}
```
This patch makes the DA scalar-dependence shortcut **_more
conservative_** by rejecting scalar non-anti and allowing input/output
dependences. This preserves the existing safe read and write cases while
preventing the miscompile above.
The patch also updates the `loop-fusion` debug message to reflect the
narrower accepted case, updates the existing regression to check the new
debug message, and adds a new regression from the linked issue.

[LangRef] Do not allow free via synchronization in nofree (#195658)
The nofree attribute is currently specified to only forbid direct free
calls inside the function. A nofree function is still allowed to compel
a pointer to be freed by a different thread through synchronization.
This is currently only spelled out for the function-level nofree
attribute, but I assume the same semantics also hold for argument nofree
(and this matches how the Attributor implementation infers it).
The original motivation for this definition was to keep the attributes
orthogonal and independently inferable. However, the problem is that
nosync is a too strong condition: It excludes *any* synchronization, not
just synchronization that results in the free of a pointer.
Some frontends like Rust can guarantee that most pointer arguments
cannot be freed for the duration of a function call, including via
synchronization. However, they cannot guarantee that no synchronization
takes place at all. The current definition of nofree makes this
inexpressible in LLVM IR, which blocks further progress on
dereferenceable-at-point semantics.
This PR makes two changes to the nofree spec:
* Function-level nofree now disallows free via synchronization,
specified in terms of happens-before.
* Argument-level nofree is now specified in terms of provenance: The
argument has derived provenance that makes it UB to free during the
execution of the function (which includes freeing on another thread with
appropriate synchronization). This also clarified that argument-level
nofree only applies to the particular pointer (similar to `captures`
etc). The underlying object may still be freed via a different argument
to which the same pointer is passed.
Note: The necessary inference changes for the new semantics will
be implemented in a separate PR.

[FunctionAttrs][Attributor] Update nofree inference (#196266)
This updates nofree inference after the semantics changes in
https://github.com/llvm/llvm-project/pull/195658.
FunctionAttrs currently only supports function-level nofree inference,
so we just need to check for potentially synchronizing instructions.
Attributor also supports argument nofree, in which case we make
additional changes:
* For callsite arguments, in addition to checking nofree, we also need
to check nocapture. If the call itself doesn't free the arg, it may
still capture it and then we may free it via the captured pointer later.
The way this was handled was already incorrect prior to the semantics
changes.
* Reformulate the handling for other instructions in terms of looking
for provenance captures, as that's what the code was essentially doing,
in a crude way. I'm including this to avoid some regressions for cases
where we can no longer infer function nofree, but can still infer
argument nofree.

[LLD] [COFF] Fix handling of immediates in ARM64_SECREL_HIGH12A (#200060)
Just like for PAGEBASE_REL21, the immediate in SECREL_HIGH12A is the
byte offset, not a page offset. The byte level offset is added to the
symbol offset, which only then after that gets shifted right by 12. This
makes the handling of this immediate consistent with what MS link.exe
does.
The existing testcase had a zero immediate in the instruction for this
relocation.
This makes it clear that immediate offsets with SECREL_HIGH12A do work
fine, where the byte level offsets end up carrying over to the upper
bits.

[mlir][mem2reg] Promote memory slots through transparent view operations (#196924)
This patch enables mem2reg to operate on load/store that are made
through cast/views of the memory slot (not directly using the SSA value
produced by the allocation op).
This is done by adding a new `PromotableAliaserInterface` interface that must
be implemented by operations that define view of the slot and through which
mem2reg should still happen.
This interface comes with three APIs. The first one allows the operation to
provide new MemorySlots that are aliasing an input MemorySlot. The slot pointers
of these new MemorySlot are results of the operation.
The other two APIs allows projecting the reaching values between the input and output
MemorySlot (one API for each direction).

[mlir][spirv] Add SPIR-V NonSemantic.Graph.DebugInfo (#199519)
Add serialization and deserialization support for the SPIR-V
NonSemantic.Graph.DebugInfo.1 extended instruction set used by ARM graph
modules.
When debug info emission is enabled, serialize DebugGraph,
DebugOperation,
and DebugTensor records for graph objects, TOSA operations, graph
tensors,
and tensor constants. Emit the records after the SPIR-V objects they
reference, and make DebugOperation point at the DebugGraph result id.
Deserialize these records back into MLIR locations and diagnose
malformed
or undefined debug-info references.
Enable SPV_KHR_non_semantic_info in the default TOSA-to-SPIR-V target
environment so debug info can be emitted by default.

[GlobalISel] Replace `GIM_CheckFeatures` with `GIM_Try_CheckFeatures` (#198461)
This has two benefits. First, it slightly reduces the size of the match
table.
Secondly, if the target feature is not present, we can directly go to
the fail
case, instead of having to do another loop of the interpreter, speeding
up
rejection of rules that do not have the required target feature.
We could do the same with CheckSimplePredicate but it's less used (only
in the combiners I think)
so it is less of a priority.

[IR][FunctionAttrs] Clarify memory effects of atomics (#193768)
FunctionAttrs was treating atomic instructions, including with ordering
stronger than monotonic, as only reading/writing their operand.
I don't think doing this is correct, because we model the ordering
constraints of synchronizing atomics via reading/writing "all" memory.
So e.g. if you have a function with a release store on an argument,
marking it as argmem-only is wrong, because that would permit reordering
accesses to other locations around it. (What this PR is doing is not
*sufficient* to model this correctly due to the fence-like effects on
not-yet-escaped memory, but it brings us closer to correctness.)
I initially tried to implement mayReadFromMemory() and
mayWriteToMemory() on top of getMemoryEffects(), but this caused
significant compile-time regressions, so I've kept the logic duplicated.

These changes were done by a script fixing annotations on LLVM public

[mlir][tosa] Limit consecutive concat rewrite to MAX_TENSOR_LIST_SIZE (#199051)
Previously folding could produce an operation that would later be
considered invalid in validation due to the number of operands it has.
This change adds a check to prevent rewriting consecutive concat
operations if the resulting operation has more than MAX_TENSOR_LIST_SIZE
operands, based on the selected target environment level. If no level is
specified, folding will proceed as before.
In addition, this change rewrites the concat folder as a
canonicalization pattern, since it is not a fold of constant operands.
The change also consolidates testing in
canonicalize.mlir.

[AArch64] Fix definition of system register move instructions (#185709)
Current implementation of these instructions makes bit20 in the encoding
part of the system register operand, which is incorrect since
[specification](https://developer.arm.com/documentation/ddi0602/latest)
specifies that bit must be set to 1. This patch changes that and removes
the bit 20 from the encoding of the operand and makes it fixed field for
these instructions. It also fixes the parser and codegen by checking
that Op0 in system register name/encoding is correctly constrained to 2
or 3.
Depends on #185970

[DirectX] Generate shader debug file name part in llc (#199555)
This change modifies DXContainerGlobals pass to generate debug name
(ILDN) part in DXContainer. ILDN part allows consumers to find PDB file
containing shader debug info.
As ILDB emission PR is not merged yet, and PDB file creation is not
upstreamed yet, debug name is generated based on MD5-hash of bitcode
module in DXIL part.
This corresponds to DXC behavior when a shader is compiled with `/Zi
/Qembed_debug /Zsb` flags (with `/Qembed_debug`, DXC does not produce an
actual PDB file, but still emits ILDN, `/Zsb` tells DXC to use bitcode
from DXIL to compute hash).
However, here ILDN is emitted for any debug info flag configuration.
assuming that it won't break debug info consumers, and that PDB creation
will be added later.

[LangRef] Specify that syncscopes can affect the monotonic modification order (#189017)
If a target specifies that atomics with mismatching syncscopes appear
non-atomic to each other, there is no point in requiring them to be ordered in
the monotonic modification order. Notably, the [AMDGPU target user
guide](https://llvm.org/docs/AMDGPUUsage.html#memory-scopes) has specified
syncscopes to relax the modification order for years.
So far, I haven't found an example where this less constrained ordering would
be observable (at least with the AMDGPU inclusive scope rules). Whenever a load
would be able to see two monotonic stores with non-inclusive scope, that's
considered a data race (i.e., the load would return `undef`), so it cannot be
used to observe the order of the stores.

[flang] Fix -E -dM macro dumping for stdin and .f90 inputs (#200144)
Issue:
flang -E -dM does not consistently print predefined macros for stdin and
.f90 inputs, unlike expected behavior.
Root cause:
Flang only initialized predefined macros when preprocessing was implied
by -cpp or suffix-based inference (mustBePreprocessed), but not when -dM
alone requested macro dumping.
Fix:
Treat -dM as an explicit trigger to initialize macro predefinitions in,
and add a stdin regression test for flang -E -dM - < /dev/null.
Fixes #198234

Currently, all assumes of the same kind in an assume bundle are dropped,
even though only a single one is actually checked to be redundant and
should be dropped. This introduces a new `removeOperandFromBundleAt`,
which instead drops a bundle at a specific position. This should also be
faster, since copying the bundles can now be done into an already
correctly allocated vector.

[libc] Move fixed buffer GPU test to an integration test (#200042)
Move the `fixedbuffer` GPU test to an integration test.
libc tests are intended to be GTest style tests written with the normal
`TEST(Suite, Test)` GTest macros. Example
[here](https://github.com/llvm/llvm-project/blob/main/libc/test/include/SignbitTest.h#L32).
This test has its own `main` which ends up causing a `main multiple
definitions` linker error when compiling for SPIR-V (work in progress).
I'm not sure why this error doesn't occur for AMDGPU, probably the fact
we have to compile with a ton less compile/linker flags for SPIR-V and
one of them hides the issue.
Specifically the fix is that we don't link against
`libc/test/UnitTest/CMakeFiles/LibcTest.hermetic.dir/LibcTestMain.cpp.o`
which has its own main which conflicts with the one defined in the test.
All other tests in this directory are integration tests too.
A quick check of other uses of the `TEST_MAIN` macro also showed them
using `add_integration_test` and not `add_libc_test`.

This patch implements the lowering to CIR for exception handling.
Unfortunately the missing components of Flatten-CFG don't work here, so
we only test that we get successfully to CIR, not to LLVM-IR.
This patch runs the 'await-resume' in a try/catch, and only if that
succeeds, does it run the coroutine body (also in a try/catch if there
is an exception handler).
This is nearly identical to the implementation in classic-codegen,
except we invert the resume-eh variable's value, so we can just use a
simple `if` op for the branch.

[llubi] Add basic support for provenance modeling (#185977)
There are four solutions to model the provenance in the memory:
1. `(allocid, bitindex)` for each bit: It follows the definition of byte
type.
2. `(allocid, bitindex)` for each byte: This assumes the pointer/byte
types are always byte-sized, and requires bitextract/bitinsert to shift
by multiples of 8, as posted in
https://discourse.llvm.org/t/rfc-add-a-new-byte-type-to-llvm-ir/89522/53.
I believe this is true in most real-world cases.
3. Assign a random tag for each memory object: The tag has the same
width as the address. It is stored in the memory like addresses. Thus,
each logical byte only occupies 4 bytes. When loading a pointer, the tag
is loaded and used to recover the provenance. Incorrect bit ordering
will result in nullary provenance (with a negligible rate of false
negatives). I think it is feasible because we can always turn a false
negative into a positive with a different seed. It is also compatible
with captured components
(https://github.com/dtcxzyw/llvm-ub-aware-interpreter/blob/d15dfef5bc0c1b30b05512bbc28fddb2b50cc0b1/ubi.h#L187)
and noalias (https://jhostert.de/blog/2025/noalias/) if we maintain the
tree structure in a hashmap.
4. Maintains a `addr -> provenance` map like
[miri](https://github.com/rust-lang/rust/blob/main/compiler/rustc_middle/src/mir/interpret/allocation/provenance_map.rs).
It also looks expensive to maintain the provenance at the bit level.
This patch implements the third approach. After
https://github.com/llvm/llvm-project/pull/178666 lands, I can add more
tests to play with byte types.

[AArch64] Do not generate indexed addressing mode for volatile accesses (#196305)
Instructions performing register writeback do not set a valid
instruction syndrome, making it impossible to handle MMIO in protected
hypervisors. Suppress the use of postinc/preinc addressing modes for
volatile accesses, which may be used to interact with MMIO.
There are three different places that can form indexed addressing modes:
* GISel via isIndexingLegal()
* SDAG via getPreIndexedAddressParts() and getPostIndexedAddressParts()
* AArch64LoadStoreOptimizer
The the latter case, exclude volatile accesses on SP (which are relevant
for stack probing) and MTE tag stores, as both cannot be MMIO.
Fixes https://github.com/llvm/llvm-project/issues/173014.

[SCEV] Canonicalise round-up idiom when some bits known (#197126)
Since #174380, instcombine can clear some set bits in the added constant
in expressions like this, when A has some known-clear low order bits.
(A + 15) & ~15
This transformation is valid, but can make it harder for later passes to
recognise this idiom for rounding up to a power of 2. This is causing
the ARM MVE tail predication pass to fail on loops with a trip count
which is a multiple of a small power of 2.
The fix is to reverse the transformation when building SCEV expressions,
canonicalising to always use the largest valid value for the added
constant.

[clang][modules-driver] Precompile std modules independently of -o and final phase (#199289)
With this, Standard library modules are always precompiled as the
primary output of their `-cc1` invocation, instead of being produced as
a byproduct of compiling the Standard library modules to object files.
This also keeps Standard library module precompilation independent of
the final phase specified on the command line, so importing them keep
working under `-fsyntax-only` (and other command-line options that
specify the final phase).
This also makes the Standard library module precompilation independent
of the `-o` flag, so that a command like `clang -std=c++23
-fmodules-driver main.cpp -o main` no longer redirects the Standard
library module outputs to 'main', breaking the compilation.

[lit] Optimize ShLexer string construction (#199641)
`lex_arg_quoted` and `lex_arg_slow` methods in the `lit`'s `ShLexer`
class used `+=` for string concatenation, which was inefficient. This change
replaces that pattern by collecting string fragments in a list and using
`"".join()` at the end.

Updated `ProgressBar.py` to replace four instances of

[flang][OpenMP] Fix declare reduction accessibility in module scope (#197078)
Fix four interacting issues with OpenMP declare reduction accessibility
when reductions are declared in Fortran modules:
1. Accessibility propagation (resolve-names.cpp): Reduction symbols like
`op.+` had no linkage to the corresponding `operator(+)` accessibility.
`ApplyDefaultAccess()` now reverse-maps mangled names to their Fortran
identifiers and inherits operator/procedure accessibility.
2. USE-associated duplicate detection (resolve-names.cpp):
`FindSymbol()`
searched parent scopes and found USE-associated symbols, causing false
"Duplicate definition" errors. Changed to scope-local `FindInScope()`
with proper `UseDetails` handling that shadows USE symbols.
3. Module file serialization (mod-file.cpp): `PutUserReduction()` never
emitted accessibility, so PRIVATE was lost on module file round-trips.
Now emits `private::<identifier>` when no GenericDetails symbol already
carries PRIVATE (avoiding duplicates with PutGeneric output).
4. Reduction clause checking (check-omp-structure.cpp):
`CheckSymbolSupportsType()` scanned all module scopes ignoring
accessibility. Now skips PRIVATE reductions in the module scope scan.
Also fixes a pre-existing bug in `MakeNameFromOperator()` where the
CharBlock lengths for OR, EQV, and NEQV included the null terminator
(6/7/8 instead of 5/6/7), causing silent mismatches in StringSwitch
comparisons.
Note: `CheckSymbolSupportsType` still scans all global module scopes
rather than only USE-reachable ones. This pre-existing over-broad lookup
is improved by the PRIVATE filter added here but a proper
scope-restricted resolution is left as future work.

[DAGCombiner] Loop unfreeze step in visitFREEZE freezeOtherUses (#200120)
The first ReplaceAllUsesOfValueWith in visitFREEZE's freezeOtherUses
block can leave users of N behind: when the inner RAUW cascade
encounters a freeze user whose hash collides post-mutation, the
recursive merge prepends new freeze users to N's use-list that the outer
iterator deliberately skips (PR3018 invariant). Those leftover users
then collide with the self-cycle the next RAUW step creates, firing
"Node is not in map!" in RemoveNodeFromCSEMaps.
Wrap the unfreeze in a convergence loop so all such prepended users are
drained before the second RAUW. Each iteration strictly shrinks N's
use-set, bounded by the depth of the freeze chain.

[DenseMap] Replace tombstone deletion with TAOCP 6.4 Algorithm R (#199615)
DenseMap uses quadratic probing with lazy deletion: an erased entry
becomes a tombstone, a third bucket state alongside empty and live that
every find/insert must inspect.
Switch to linear probing with backward-shift deletion (Knuth TAOCP 6.4
Algorithm R), similar to the SmallPtrSet change #197637. This removes
the tombstone state entirely.
In exchange, erase now relocates the following live entries to close the
hole, so it invalidates iterators and references other than the erased
one. For callers that cache pointers into the bucket array,
erase(Key, OnMoved) and erase(iterator, OnMoved) fire a callback once
per
shifted bucket, so fix-ups cost O(cluster) rather than O(NumEntries).
ValueHandleBase::RemoveFromUseList uses this to refresh each moved
handle's PrevPtr.
Linear probing is more vulnerable to primary clustering than quadratic
probing, so this relies on the stronger DenseMapInfo<T*>::getHashValue
mixer from #197390.
Operation distribution when compiling CGExpr.cpp/ScalarEvolution.cpp:
62.8% lookups, 34.3% inserts, 2.9% erases. The heaviest DenseMap
specializations have pointer keys and 16-byte key/value pairs.
Alternatives such as Robin Hood hashing, Verstable, and Boost's
unordered_flat_map were evaluated; they are slower and have a larger
code footprint. I believe the current in-band sentinel value approach,
despite the pain (#146595), is the best, or at least very difficult to
beat.

[libc] Don't touch str_end in strto* and wcsto* functions when base is incorrect (#200073)
Updates the behavior of `stro*` and `wcsto*` endpoints to not touch
`str_end` pointer when the provided value of `base` is incorrect and
errno is set to `EINVAL`.
`strto*` and `wcsto*` functions accept `base` as an input argument,
which can only be 0 or lie in [2,36] range. In case of invalid argument,
the functions should return 0 and set errno accordingly. Should the
"output argument" of `str_end` be updated in this case to point to the
beginning of the input string?
* C standard is unclear about it -
is says that `str` should be stored in `str_end` **if `str` is empty or
does not have the expected form** -- but there is no "expected form" for
invalid base values.
* POSIX standard explicitly mentions that for incorrect base value errno
should be set to `EINVAL` and points out that the value of `str_end`
is **unspecified** in this case.
Known implementations don't have a universal agreement about it:
* musl sets `str_end` unconditionally
* glibc doesn't do that in `EINVAL` case
* newlib doesn't do that either.
LLVM-libc used to unconditionally set `str_end` even in `EINVAL` case,
which is changed in this PR. This would not only help with portability,
but makes sense by itself - if input arguments are clearly invalid,
let's not touch output arguments either.

[InstCombine] Fold zext into de-interleaving (factor=2) instructions (#195330)
Given the following de-interleaving shufflevectors and the consuming
zexts:
```
%f0 = shufflevector <8 x i32> %v, <4 x i32> <i32 0, i32 2, i32 4, i32 6>
%f1 = shufflevector <8 x i32> %v, <4 x i32> <i32 1, i32 3, i32 5, i32 7>
%z0 = zext <4 x i32> %f0 to <4 x i64>
%z1 = zext <4 x i32> %f1 to <4 x i64>
```
We can actually bitcast the input value, `%v`, first into a vector type
with double the element size but half the vector length, before
replacing zexts with simple arithmetics on this new bitcast:
```
%bc = bitcast <8 x i32> %v to <4 x i64>
%z0 = and <4 x i64> %bc, splat (i64 4294967295)
%z1 = lshr <4 x i64> %bc, splat (i64 32)
```
This transformation is almost always benefitial as shufflevector is
generally more expensive than normal arithmetics.

[Clang][Sema] Use correct DeclContext when checking 'this' (#163243)
As mentioned in #163089, clang crashes for the following inputs:
```cpp
struct S {
static void f() {
auto x = []() -> decltype(this) {};
}
};
```
```cpp
struct S {
static void f() {
auto x = []() noexcept(decltype(this)()) {};
}
};
```
The crash happens because we currently pass `CurContext` to
`isLambdaCallWithExplicitObjectParameter` in `Sema::CheckCXXThisType`
when we should be passing `DC` (returned from
`getFunctionLevelDeclContext`).
Fixes #163089.

[lldb][Darwin] Save "most recent SDK root" in local var (#200095)
In PlatformRemoteDarwinDevice::GetSharedModule we have an array of "sdk
root" directories (aka DeviceSupport directories) for a remote device,
which contain all of the system shared libraries on the local mac. We
may have 6 SDK Root directories for different OS builds. We try to
identify the correct one for the target based on version number, but
when we find a file with a matching UUID in one directory we set that as
the "most recently successful" directory, and start our searches with
that one. Then we fall back to searching all the other directories.
Since adding parallel module loading, because this method doesn't lock
access to the "most recently successful directory"
(m_last_module_sdk_idx), we could check the m_last_module_sdk_idx
directory, and then if that was unsuccessful, check all other entries !=
m_last_module_sdk_idx. But m_last_module_sdk_idx could mutate via
another thread, and we skip one of our SDK Root directories. Resulting
in reading a binary out of memory, when we had a local copy of it.
This PR reads the value of m_last_module_sdk_idx into a local const, and
uses the same local index to check for it -- and if not found, to skip
that directory when iterating over all directories again, instead of
adding locking around access to this.
The array itself is created when the Platform is initialized and not
mutated when parallel-binary-loading, so there are no concerns with
that.

[lldb][NativePDB] Use decl context from a method's class (#199221)
When we look up the parent decl context for a method, we used to look
for that by name. For "regular" types that works well.
Say, we have a `struct ns::Foo` and `ns::Foo::bar`. We'd search for
`ns::Foo` and use its context.
For special types - mainly lambdas - this doesn't work. They can't be
found by looking for the name we get from the function symbol. That name
won't be in the TPI hash table we use.
I'm not fully sure under which name they're in that table. For example,
if we get the name `Foo::fun::<lambda_1>::operator()` from the function
symbol, we'd look for `Foo::fun::<lambda_1>`. This fails. A class with
this name is actually present, but it has a different unique name. Its
unique name demangles to `` `public: void __cdecl
Foo::fun(void)'::`1'::<lambda_1> `` which doesn't match what we searched
for. That might be the issue.
If we can't find a class/struct, we create namespaces. So before, we
created namespaces for each segment and added a regular function inside.
This was wrong for methods.
However, we can tell that a function is a method by looking at its
function type. And we know the parent class from this type. With this PR
that parent class is used if it's available.

[flang][OpenMP] Fix crash on standalone ordered with depend(source|sink:) (#200193)
A standalone ordered construct using the pre-OpenMP 5.2 depend(source) /
depend(sink:) spelling crashed flang with an assertion failure in
buildConstructQueue ("Construct decomposition failed"), or emitted a
TODO when assertions were disabled.
These dependence types are valid on ordered since OpenMP 4.5, but flang
represents them internally as a doacross clause, which construct
decomposition only accepts from OpenMP 5.2. As a result, decomposition
produced an empty output and tripped the assertion at every OpenMP
version below 5.2 (including the default 3.1).
Lowering of the standalone ordered directive is not implemented yet
(genOrderedOp only emits a "not yet implemented" message and ignores the
construct queue). Build the construct queue only for the
block-associated variant and emit the TODO directly for the standalone
directive, so the decomposition that would otherwise assert is no longer
reached.
Note: at versions below 4.5 the construct is technically invalid, but
flang's semantics accepts it silently. Making semantics emit a "requires
OpenMP 4.5" error/warning is probably a good idea.

[Instrumentor] Introduce BasePointerIO to communicate base pointer information (#197607)
Loads, stores, and later probably calls, can request a base pointer info
object from the user runtime. This object is queried right after the
base pointer of the operation is defined, and then passed to the
pre/post runtime calls of the loads and stores. This allows users to
inspect pointers early and once, but provide the analysis results to all
operations that might be executed in loops. A potential use case is to
lookup the size and start of the underlying object and then provide
those to the access runtime calls for in-bounds checking.

[CIR] Omit nsw/nuw on integer vector binops (#199123)
CIRGen was attaching `nsw` to `cir.add` on `!cir.vector` integer types
because the signed-overflow path keys off `compType` (the element type,
still `!s32i`), while the verifier only allows `nsw`/`nuw` on scalar
`!cir.int` results. That mismatch showed up 144 times in the libcxx
CIR sweep on `std::experimental::simd` — `experimental/__simd/vec_ext.h`
increment/decrement (`__data + 1` / `__data - 1`).
Classic CodeGen never enters the signed-overflow block for vector
computation types; CIR now skips the scalar `nsw`/`nuw` path when the
MLIR operand is an integer vector, and uses `getAs<VectorType>()` for
`compType` so typedef-wrapped GCC vectors resolve the element type
correctly.

We now allow to have instrumentation opportunities for many instructions
(=opcodes) to bundle common classes together. Users can use filters on
the opcode, type-id, and size to statically select what they are
interested in.
Coded with Claude.

[llvm] Fix LLVMOrcTargetProcess symbol export with MinGW/Cygwin shared libs (#174266)
When any symbol in a DLL carries dllexport, the MinGW/Cygwin linker
switches to exclusive-export mode and omits all other symbols from the
export table. LLVMOrcTargetProcess uses LLVM_ALWAYS_EXPORT (__declspec(
dllexport)) so its symbols can be found via GetProcAddress from a
statically linked executable, which triggers this behaviour.
Add --export-all-symbols to LLVMOrcTargetProcess for MinGW/Cygwin
BUILD_SHARED_LIBS builds to restore full symbol export.

[2/3][RegAlloc][LiveRegMatrix] Fix inconsistency when fold creates a CopyMI (#197776)
When TargetInstrInfo::foldMemoryOperand produces a side-effect CopyMI,
the copy destination vreg's LiveInterval is extended via addSegment. If
that vreg is already assigned in LiveRegMatrix, the matrix becomes
inconsistent because it still holds the old (smaller) interval.
Fix this in two places:
- InlineSpiller::foldMemoryOperand: unassign the vreg from the matrix
before addSegment, reassign after, so the matrix reflects the updated
interval.
- LiveRangeEdit::foldAsLoad: notify the delegate via
LRE_WillShrinkVirtReg before addSegment.

verification as in https://github.com/llvm/llvm-project/pull/197778 but

type and casts it to an int (as this is a pretty useful task, that I
believe I've seen before).

While making a test for the first bug, I found that `frame variable
recognizer_arg` will
both successfully print the variable, and also report a false positive
error:
```
error: <user expression>:1:1: use of undeclared identifier 'recognizer_arg'
1 | recognizer_arg

This change fixes both bugs, including when using `--regex`.

[llvm-offload-binary] Fix test failures on z/OS by splitting malformed tests (#200258)
## Summary
This PR fixes test failures in `llvm-offload-binary.ll` on z/OS (and
potentially other EBCDIC platforms) by splitting the malformed file
tests into a separate test file.
## Problem
The test was failing on z/OS because it uses `printf` with octal escape
sequences to create malformed binary test data:
```bash
printf "\020\377\020\255\012" > %t9
```
On z/OS, the shell's I/O redirection performs automatic EBCDIC-to-ASCII
translation on the output from `printf`. This means the binary data
written to the file gets translated, resulting in different bytes than
intended. The malformed test data is therefore not created correctly,
causing `llvm-offload-binary` to fail in unexpected ways or not produce
the expected error messages.
## Benefits of this solution
- Main test file now passes on all platforms including z/OS
- Malformed file error handling tests are preserved for ASCII-based
systems
- Clear separation of concerns between standard tests and
platform-specific tests
- No loss of test coverage on supported platforms

lowering recognize allocatable WHERE self-updates as aligned even when

This avoids generating full-sized RHS temporaries for these masked

[PGO][HIP] Skip ROCm interceptor in profile-only compiler-rt builds (#200111)
PR #177665 made `libclang_rt.profile.a` merge `RTInterception` and
`sanitizer_common` object libs to support the `hipModuleLoad*` host
interceptor added in `InstrProfilingPlatformROCm.cpp`. Those object-lib
targets are only created when `COMPILER_RT_BUILD_SANITIZERS / _MEMPROF /
_XRAY / _CTX_PROFILE` is enabled (see `compiler-rt/lib/CMakeLists.txt`),
so a profile-only configuration fails at configure time:
```
CMake Error at cmake/Modules/AddCompilerRT.cmake:365 (add_library):
Error evaluating generator expression:
$<TARGET_OBJECTS:RTInterception.x86_64>
Objects of target "RTInterception.x86_64" referenced but no such target
exists.
Call Stack (most recent call first):
lib/profile/CMakeLists.txt:233 (add_compiler_rt_runtime)
```
Fix: gate the object-lib merge on the `RTInterception.<arch>` /
`RTSanitizerCommon*.<arch>` targets actually existing, and drop
`InstrProfilingPlatformROCm.cpp` from `PROFILE_SOURCES` in that case so
the static archive stays self-contained. The host-side hook
`__llvm_profile_hip_collect_device_data` is already declared weak in
`InstrProfilingFile.c` (PR #200101), so its absence is fine at link
time.
Verified:
- Profile-only standalone compiler-rt build
(`-DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_MEMPROF=OFF
-DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_CTX_PROFILE=OFF
-DCOMPILER_RT_BUILD_PROFILE=ON`) now configures and links cleanly.
- Default runtimes build still merges the object libs and produces the
interceptor; `check-profile` 134/134 pass.

handle the splice form.
It adds a pattern match helper to match both vp.reverse and
vector.splice.right. If vp.reverse is removed in future, then this
pattern match helper can be removed.

[CIR] Add emitBuiltinWithOneOverloadedType helper (#199518)
Port `emitBuiltinWithOneOverloadedType<N>` from classic
CodeGen(`CGBuiltin.h`) to `CIRGenFunction` so the common pattern "emit N
scalar operands and call an LLVM intrinsic whose return type matches the
first operand" can be written as a one-liner across all targets.
Used it to simplify a few existing AMDGPU builtin lowerings (`div_fmas`,
`ds_swizzle`, `readlane`, `readfirstlane`).

[profcheck] Fix profile metadata propagation for Large FP Operations (#175864)
This PR improves the propagation of profile metadata within the
ExpandIRInsts pass. When lowering non-standard floating-point
operations, the pass now ensures that branch weights are correctly
attached to the generated control flow, preventing the loss of profile
data during IR expansion.
This enhancements cover the conversions between non-standard
floating-point formats and large integers (e.g., `fptosi/fptoui`,
`sitofp/uitofp` involving `i129`).
This PR implements Heuristic-Based Branch Weights labeling using
established heuristics for Floating-point rounding overflow and
saturation checks and adds detailed comments within the expansion logic
to explain the rationale behind specific branch weight choices and the
underlying mathematical invariants.
Please refer to the implementation details in the source code for the
specific branch weight values and the logic governing their application.

[lldb] Make TestSBModule a no-SHARED_BUILD_TESTCASE (#188265)
Building libfoo.a twice (quickly) confuses the cache in
ObjectContainerBSDArchive (which works only with second granularity),
and causes the second test to fail due to accessing wrong parts of the
file.
I'm also making this a NO_DEBUG_INFO_TESTCASE as the debug info
distinction is not particularly relevant for this test. Technically,
this would be enough as the collision is between two debug info variants
of the same test case, but SHARED_BUILD_TESTCASE=False seems like a more
principled fix.

[BPF] crash fix for memcpy with unsupported alignment (#199541)
### Summary
BPF only has scalar load/store opcodes up to 8 bytes and `memcpy` with
16 byte alignment crashes with `llvm_unreachable("unsupported memcpy
alignment");` in `BPFInstrInfo::expandMEMCPY`
### Issue
The crash can be reproduced from Rust code like:
```rust
#[no_mangle]
pub extern "C" fn entry(src: *const u128) -> u64 {
let mut dst = [0u128; 2];
unsafe { ptr::copy_nonoverlapping(src, dst.as_mut_ptr(), 2) };
let _ = black_box(dst);
0
}
```
This produces a `memcpy` with 16-byte alignment and
`BPFSelectionDAGInfo::EmitTargetCodeForMemcpy` emit the `BPFISD::MEMCPY`
pseudo for 16-byte alignment. That pseudo later reaches `expandMEMCPY`
during the Post-RA pseudo expansion pass and hits:
```
llvm_unreachable("unsupported memcpy alignment");
```
The crash report looks like:
```
= note: PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/
and include the crash backtrace and instructions to reproduce the bug.
Stack dump:
0. Running pass 'Function Pass Manager' on module 'linked_module'.
1. Running pass 'Post-RA pseudo instruction expansion pass' on function '@entry'
```
### Fix
Return `SDValue()` in `BPFSelectionDAGInfo::EmitTargetCodeForMemcpy`
when the alignment is larger than 8 bytes. LLVM then naturally falls
back to the existing libcall path and emits `call memcpy` instead of
creating a pseudo instruction that cannot be expanded later.
Since `memcpy`, `memset`, and `memmove` are now whitelisted, I think
this fallback behavior is the right fix: unsupported target expansion
should decline and use the existing libcall path instead of crashing.
### Opt-in controls around libcalls
I also want to use this chance to introduce two opt-in controls around
libcalls for VM/runtime use cases built on top of the BPF backend (both
controls are opt-in and disabled by default, so existing kernel projects
and current BPF behavior remain unchanged),
### --bpf-max-stores-per-memfunc
First, an opt-in flag to control over
`BPFSelectionDAGInfo::getCommonMaxStoresPerMemFunc()`.
Today, the target memory expansion path uses:
```c++
if (StoresNumEstimate > getCommonMaxStoresPerMemFunc())
return SDValue();
```
This threshold controls whether `EmitTargetCodeForMemcpy` continues
emitting the BPF memory pseudo(which is later expanded with load/store
ops) or falls back to the libcall path.
Currently this value is effectively fixed at 128, which means most
constant-size memory operations are expanded into inline load/store
sequences. Exposing the threshold gives VM/runtime users a way to allow
more memory operations to fall through to libcalls, while keeping the
current default behavior unchanged.
### --bpf-allows-libcalls (PR #199542 )
Second, an opt-in flag to allow additional libcalls beyond the currently
whitelisted ones.
Today BPF rejects unsupported libcalls here:
```c++
if (Sym != BPF_TRAP && Sym != "__multi3" && Sym != "__divti3" &&
Sym != "__modti3" && Sym != "__udivti3" &&
Sym != "__umodti3" && Sym != "memcpy" &&
Sym != "memset" && Sym != "memmove")
fail(
CLI.DL, DAG,
Twine("A call to built-in function '" + Sym +
"' is not supported."));
```
With the new flag enabled, _this error path is skipped_ so VM/runtime
environments can provide their own libcall implementations.
For VM runtimes using the BPF backend, libcalls are useful because they
create an interface between normal compiler-generated code and
runtime-specific optimization. We have already explored this model for
u128 arithmetic, where libcalls allow normal Rust code to stay unchanged
while the runtime can provide optimized behavior:
https://blueshift.gg/research/accelerating-u128-math-with-libcalls-and-jit-intrinsics
The same idea applies to memory operations. Users can continue writing
normal Rust like `ptr::copy_nonoverlapping`, while the runtime can
choose an implementation tailored to its execution environment.
Both controls are opt-in and disabled by default, so existing kernel
projects and current BPF behavior remain unchanged.

[Clang] Mark new as inaccessiblememonly if sane (#197199)
If `-fassume-sane-operator-new` (the default), assume that `operator
new` does not read or write accessible memory.
Currently, this assumption already exists due to special treatment in
BasicAA. I'd like to remove this special treatment (see
https://github.com/llvm/llvm-project/pull/197180), and instead rely only
on the `memory` attribute.
It's worth noting that this is consistent with GCC's interpretation of
the flag (where it is also enabled by default):
> [...] With -fassume-sane-operators-new-delete option GCC may assume
that calls to the replaceable global operators from new or delete
expressions or from __builtin_operator_new or __builtin_operator_delete
calls don’t read or modify any global variables or variables whose
address could escape to the operators (global state; except for errno
for the new and new[] operators). [...]

[LoongArch] Emit DTPREL relocations for TLS debug info (#199326)
Teach the LoongArch backend to lower thread-local debug references using
target-specific DTPREL relocations.
This adds .dtprelword and .dtpreldword directive parsing and streaming,
introduces 32-bit and 64-bit DTPREL fixups and ELF relocation mappings,
and uses a LoongArch target object file to represent debug TLS symbols
as VK_DTPREL expressions. LoongArchAsmPrinter is updated to emit the new
directives for debug TLS values in assembly output.
Add MC and debug info tests for assembly emission and object
relocations.

[SystemZ] Handle pointer size correctly in getVectorBitmaskConversionCost(). (#200171)
Unfortunately, getScalarSizeInBits() returns 0 for PointerTy, which
means that the loop vectorizer got way too high costs for sext i1 after
a compare(ptr, 0).
There is already a version of getScalarSizeInBits() in
SystemZTargetTransformInfo.cpp that handles this, so this is fixed by
using this in the needed places.
As a result, a few more loops are vectorized, and perl improves ~1%.

[SystemZ] Global Stackprotector and associated location section (#169317)
This commit allows `-mstack-protector-guard=global` for `s390x`.
It also adds a new arch-specific option
`-mstack-protector-guard-record`, analogous to `-mrecord-mcount`, which
will cause `clang` to emit a `__stack_protector_loc` section containing
all the locations in the output binary that load the stack guard
address, for the purposes of later rewriting of those loads by the
kernel. This new option only works together with the `global` stack
protector.
In order to minimize exposure of the stack guard, both the storing of
the stack guard onto the stack, and the later comparison of that value
against the reference value, are handled via direct mem-to-mem
instructions, those being `mvc` and `clc`.
This is achieved by introducing two new pseudo instructions,
`MOVE_STACK_GUARD` and `COMPARE_STACK_GUARD`, which are inserted by the
DAGCombiner after SelectionDAG construction. These pseudos stick around
throughout the entire backend pipeline, and are lowered only in the
AsmPrinter.
This commit also adds tests for both kinds of stack protectors (tls and
global), for the proper insertion of the pseudos, the proper emission of
the, `__stack_protector_loc` section, as well as the option
compatibility checks for the new options.

[IR] Skip remove_if scan for empty maps in removeNotPreservedAnalysis (#200292)
removeNotPreservedAnalysis runs after every legacy-PM pass. #198982
changed it to DenseMap::remove_if, which iterates the raw bucket array
even when the map is empty. The old begin()/end() loop did not:
begin()'s
makeBegin returns end() directly for an empty map (its "avoid advancing
past empty buckets" shortcut), so the loop touched no buckets. These
maps
are usually empty here but keep a grown bucket array after their entries
are erased (a 64-bucket array when compiling sqlite3.i at -O0 -g), so
remove_if walks empty buckets for nothing, regressing instructions:u
(most visible at -O0). #199571 was a small fix for the out-of-lined
remove_if call; this addresses the dominant cost.
Skip empty maps, which fixes the regression:

[VectorCombine] Don't scalarize atomic loads (#200263)
scalarizeLoad tries to convert e.g.

%b = extractelement %a, 1
into a scalar load. Before this patch it would do this even when the
load is atomic, but in doing so it accidentally dropped the atomicity of
the load!
Although it is correct to apply this transformation to unordered
atomics, for now we simply don't apply this pass to atomics at all.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

[LSR] Improve the recognition of vscale immediates (#196998)
Previously, the extraction of vscale immediates was handled the same as
the non-scalable case. That is we'd look for a `vscale * constant`
scMulExpr on the LHS of the SCEV expression.
However, within a SCEV expression operands are ordered by "complexity",
which is defined (mostly) by the order of the SCEVTypes enum:
https://github.com/llvm/llvm-project/blob/bcb84e234980ca42ee47e21e4c97180c788c946a/llvm/include/llvm/Analysis/ScalarEvolutionExpressions.h#L38-L59
So, (non-scalable) constants would always occur on the LHS as the
simplest expression type, but a scMulExpr could occur later in the
operand list for a scAddExpr (e.g., after a sext/zext expression). This
meant in some cases we'd fail to find vscale immediates.
This patch updates `ExtractImmediate` to search later operands to find
vscale offsets, and prefer vscale offsets based on the access type and
current BaseOffset. So for scalable accesses, we prefer finding vscale
immediates over fixed immediates when both are present.

[Flang] Move builtin .mod generation into runtimes (Reapply #137828) (#171515)
Reapplication of #137828 and #169638
Move building the .mod files from openmp/flang to openmp/flang-rt using
a shared mechanism. Motivations to do so are:
1. Most modules are target-dependent and need to be re-compiled for each
target separately, which is something the LLVM_ENABLE_RUNTIMES system
already does. Prime example is `iso_c_binding.mod` which encodes the
target's ABI. Constants such as `c_long_double` also have different
values).
Most other modules have `#ifdef`-enclosed code as well. For instance
this caused offload targets nvptx64-nvidia-cuda/amdgpu-amd-amdhsa to use
the modules files compiled for the host which may contrain uses of the
types REAL(10) or REAL(16) not available for nvptx/amdgpu.
2. CMake has support for Fortran that we should use. Among other things,
it automatically determines module dependencies so there is no need to
hardcode them in the CMakeLists.txt.
Currently the dependencies between builtin modules and `omp_lib.mod`
seem to be incorrect:
https://github.com/llvm/llvm-project/pull/174474#issuecomment-3880189581
3. It allows using Fortran itself to implement Flang-RT. Currently, only
`iso_fortran_env_impl.f90` emits object files that are needed by Fortran
applications (#89403). The workaround of #95388 could be reverted (PR
#169525).
If using Flang for cross-compilation or target-offloading, flang-rt must
now be compiled for each target not only for the library, but also to
get the target-specific module files. For instance in a bootstrapping
runtime build, this can be done by adding:
`-DLLVM_RUNTIME_TARGETS=default;nvptx64-nvidia-cuda;amdgpu-amd-amdhsa`.
Some new dependencies come into play:
* openmp depends on flang-rt for building `lib_omp.mod` and
`lib_omp_kinds.mod`. Currently, if flang-rt is not found then the
modules are not built.
* check-flang depends on flang-rt: If not found, the majority of tests
are disabled. If not building in a bootstrpping build, the location of
the module files can be pointed to using
`-DFLANG_INTRINSIC_MODULES_DIR=<path>`, e.g. in a flang-standalone
build. Alternatively, the test needing any of the intrinsic modules
could be marked with `REQUIRES: flangrt-modules`.
* check-flang depends on openmp: Not a change; tests requiring
`lib_omp.mod` and `lib_omp_kinds.mod` those are already marked with
`openmp_runtime`.
As intrinsic are now specific to the target, their location is moved
from `include/flang` to `<resource-dir>/finclude/flang/<triple>`. The
mechnism to compute the location have been moved from flang-rt
(previously used to compute the location of `libflang_rt.*.a`) to common
locations in `cmake/GetToolchainDirs.cmake` and
`runtimes/CMakeLists.txt` so they can be used by both, openmp and
flang-rt. Potentially the mechnism could also be shared by other
libraries such as compiler-rt.
`finclude` was chosen because `gfortran` uses it as well and avoids
misuse such as `#include <flang/iso_c_binding.mod>`. The search location
is now determined by `ToolChain` in the driver, instead of by the
frontend. Another subdirectory `flang` avoids accidental inclusion of
gfortran-modules which due to compression would result in
user-unfriendly errors. Now the driver adds `-fintrinsic-module-path`
for that location to the frontend call (Just like gfortran does).
Since the driver determines the location,
tests invoking `flang -fc1` and `bbc` must also be passed the location
by llvm-lit. This works like llvm-lit does for finding the include dirs
for Clang using `-print-file-name=...`.

[Compiler-rt][CMake][BoundsSafety] Add `COMPILER_RT_ENABLE_TEST_SUITES` to control which test suites are enabled (#196385)
This change introduces a new CMake cache variable
`COMPILER_RT_ENABLE_TEST_SUITES` that allows users to have fine-grained
control over which test suites are included and therefore run when
running `ninja check-all`.
For example building with `COMPILER_RT_ENABLE_TEST_SUITES=builtins;asan`
will only enable the builtins and asan tests under `compiler-rt/tests`.
The default value of `COMPILER_RT_INCLUDE_TESTS` is `all` which is a
special value that includes everything and it being the default means
this patch preserves existing behavior. Note this new option only has
affect when `COMPILER_RT_INCLUDE_TESTS` is On.
The primary use case for this change is it allows controlling tests that
don't have a corresponding runtime to be enabled/disabled. An example of
this is the `shadowcallstack` test suite. `-fbounds-safety` also has a
downstream test suite in compiler-rt like this. Previously there was no
way to disable including these tests when `COMPILER_RT_INCLUDE_TESTS`
was on.
The `-fbounds-safety` test suite will be upstreamed once the necessary
clang pieces exist upstream.
A side benefit of this change is it allows building runtimes but not
testing some of them which can be useful in some testing environments
(e.g. smoke-test). It is not the primary motivation though.
While the existing `COMPILER_RT_BUILD_<NAME>` options can be used to
prevent running tests (by not building corresponding runtimes) that
isn't a good solution because it:
* Doesn't work for tests that have no corresponding runtime to be built
like `shadowcallstack` because there's no CMake option for it.
* Requires specifying multiple CMake options to disable building each
runtime that we don't want tested. This approach disallows "building
but not testing certain runtimes" and also is annoying to maintain
because its effectively a subtractive list (you say what you don't
want) that has to be updated everytime a new runtime is introduced
whereas COMPILER_RT_ENABLE_TEST_SUITES is an additive list (you say
what you want) that doesn't need modifying everytime a new runtime is
introduced.
To implement this all test directories in `compiler-rt/test` are now
added through the `compiler_rt_test_runtime()` function which has been
adapted to accommodate all use cases.
