[llvm-exegesis] Add AArch64 operand initializers, SetRegTo (#169912)
Make llvm-exegesis more usable on AArch64 by doing the following:
Add some missing exegesis handling of register classes;
Add some missing LLVM AArch64 OperandTypes.
Llvm-exegesis can now handle many more AArch64 instructions.
AArch64 load/store instructions are not yet supported by llvm-exegesis,
until https://github.com/llvm/llvm-project/pull/144895 lands.

[clang] Enable fat-lto-object support for COFF targets (#172936)
This change allows using clang's `-ffat-lto-objects` flag with COFF
targets such as `i386-pc-win32`.
Follow-up to 759fb0a224e85c01fffcd42b1e71a4bea6fc757e from which it was
split off. The added tests are adapted from the pre-existing ELF tests.

[libc][wctype] Create generation script for classification lookup tables (#172042)
[#172040](https://github.com/llvm/llvm-project/issues/172040)
This patch implements the scripts for generating the lookup tables and
associated utils for wctype classification functions. Not all Unicode
properties are covered as not all need a lookup table, the rest will be
hardcoded. The size of the generated tables is 47,8KB.

llvm: Convert some assorted lit tests to opaque pointers (#174564)
Some of the MIR test hit a bug where it errors if there is a
raw global reference as the referenced value. Worked around some
of those by just keeping a no-op bitcast constant expression.

[Clang][Sema] Fix crash when applying sentinel to block variable (#173866)
This PR avoids the crash in Clang Sema when the sentinel attribute is
applied to a block variable, see https://github.com/llvm/llvm-project/issues/173820.
Basically, handleSentinelAttr always treated the type as a function with
a prototype which is not true for block variables like void (^a)() and
it caused Clang to crash. Now Clang will print a warning instead of
crashing.

[OpenMP] Add default stub for virtual methods (#174594)
Summary:
Recent OpenMP patches have added real support for virtual functions on
the device side. However, we don't provide some of the C++ ABI functions
that are emitted when using these. In practice these functions just call
`std::terminate` so we can just trap here. These are marked weak so they
will be overridden by a more correct implementation if not defined and
will also not extract on their own from a static library.

[X86] use `VPMADDWD` for widening adjacent addition (#174149)
The `_mm256_madd_epi16` intrinsic performs first a pointwise widening
multiplication, and then adds adjacent elements. In SIMD versions of the
adler32 checksum algorithm, a trivial multiplication by an all-ones
vector is used to get just the widening and addition behavior.
In the rust standard library, we like to implement intrinsics in terms
of simpler building blocks, so that all backends can implement a small
set of primitives instead of supporting all of LLVM's intrinsics. When
we try that for `_mm256_madd_epi16` in isolation it works, but when one
of the arguments is an all-ones vector, the multiplication is optimized
out long before the `vpmaddwd` instruction can be selected.
This PR recognizes the widening adjacent addition pattern that adler32
uses directly, and manually inserts a trivial multiplication by an
all-ones vector. Experimentally, performing this optimization increases
adler32 throughput from 41 gb/s to 67 gb/s

[clang][Driver][SPIR-V] Allow linking IR using llvm-link (#169572)
SPIR-V does not have a production-grade linker so it is often necessary
to stay in LLVM-IR as long as possible and only convert to SPIR-V at the
very end.
As such, it is common that we want to create a BC library that is linked
into a user program (motivating example here is the OpenMP device RTL).
We only convert to SPIR-V at the very end when we have a fully linked
program.
Other targets can achieve a similar goal by using LTO to get a linked-BC
file, but the SPIR-V linker does not support LTO, so we have no way to
do it with `clang`. We can do it with `llvm-link` directly, but my
understanding is that it is not intended to be directly called in
production workflows and does not fit well into code that supports
multiple targets.
Extend the existing behavior for `HIP` that allows `-emit-llvm` without
`-c`.

[NFCI] [Darwin] Add APPLE_TARGET_IS_HOST lit option to compiler-rt (#174522)
Darwin supports running tests on targets other than the host machine
e.g. simulators. In such configurations, tests are run via a wrapper
script (e.g. iossim_run.py).
This refactors the lit test config to use a dedicated option to
distinguish test suites that run on the host from those that run in any
other configuration. This will allow the test suites to distinguish a
local osx configuration from a "remote" one.

[TSan] Fix TSan instrumenting pointers from non-default address spaces (#174518)
Casting a pointer to a different address space is a nice trick to
prevent an access from being instrumented by sanitizers such as ASan.
However, this trick is currently broken, as the test demonstrates.
A minimal C PoC of the issue is:
```
void access(void *p) {
auto tmp = (unsigned long __attribute__((address_space(1))) volatile *)p;
*tmp = 0;
}
```
Under fsanitize=address, the access does not get instrumented, but under
fsanitize=thread, it does.
(Note: Before this patch, this test will actually hit a CallInst
assertion if you have them turned on, because the TSan runtime functions
are defined to take pointer arguments, and non-default address space
pointers are not compatible).

[llvm] Bypass sandbox in `sys::fs::createTemporaryFile()` (#174491)
Based on the name of the function, I think it's safe to assume
`sys::fs::createTemporaryFile()` is not to be used for formal compiler
outputs and should only be used for compiler-internal outputs (caches,
debugging output, etc.). Thus, it should be fine to disable the IO
sandbox and allow bypassing `vfs::OutputBackend` here.

[libc++] Refactor atomic_waitable_traits into its own header and remove pre 20 support (#173157)
It makes sense to decouple traits from the things they describe, since
that's the purpose of traits. Furthermore, this will make it possible to
reuse these traits from other places in the library (e.g. <semaphore>)
outside of the synchronization library.
Pre-C++20 support is removed as a drive-by since the synchronization
library does not support pre-C++20 anymore. This makes it possible to
simplify a few constructs by using concepts.

[cross-project] Add tests for LLDB data-formatters for llvm::ArrayRef (#173238)
This patch adds the bare-minimum tests for the LLDB `llvm::ArrayRef`
formatters. Since this would be the first LLVM data fromatter test for
LLDB, I wanted to keep the test itself minimal and mainly set up/agree
on the infrastructure (i.e., CMake machinery, etc.).
The setup mimicks that of GDB. The main differences are:
1. the GDB formatter tests put all the test cases in one monolithic test
file, whereas I'm planning on having one test-file per LLVM container.
2. the GDB formatter tests currently only get run if LLVM was built with
debug-info. Not sure we have any build-bots out there running this
configuration. In this patch we rely on just the debug-info from the
LLVM headers (see latest commit). That way the tests get more
consistently run (at least our public macOS buildbot runs the
cross-project-tests in Release+Asserts).

[Clang] prevent crash in early parsing of enable_if for C function declarators with identifier-list parameters (#174017)
Fixes #173826
---
This patch resolves an issue where Clang could crash while parsing the
`enable_if` attribute on C function declarators with identifier-list
parameters.
In C, identifier-list function declarators use parameter identifiers
rather than full parameter declarations, as specified by the C spec.
Since `enable_if` is parsed early to participate in redeclaration checks
https://github.com/llvm/llvm-project/blob/0f3a9f658a7f459b9aa701ec42a999b645653862/clang/lib/Parse/ParseDecl.cpp#L674-L675
the parser could encounter such identifiers before their parameter
declarations exist and incorrectly assume they were already formed,
leading to an assertion failure.
This change makes the early `enable_if` parsing path handle parameters
that have not yet been declared, preventing the crash while preserving
existing behavior for well-formed function prototypes.

[LLVM] Successor count added to InstCount (#171670)
Counts the number of Basic Block successors when stats are enabled
We want to track this metric for a project in which we analyze the
effects of having LLVM Intermediate Representation (IR) code with a high
number of branches. We plan to use these capabilities to learn how
enabling memory safety features increases the branchiness in LLVM IR and
further how it affects binary compilation time and the resulting binary
performance.

[compiler-rt] Support default-True lit config options (follow up to #174522) (#174642)
The option added in #174522 breaks simulator tests, since `set_default`
overrides `False` values with the default.
Since these options are either string or boolean, this patches
set_default to override only un-set or empty string values (empty string
is not truth-y and therefore would be overwritten by defaults currently,
so this is NFCI)

[clang] Reference-count `ModuleCache` non-intrusively (#164889)
The `ModuleCache` class is currently reference-counted intrusively. As
explained in https://github.com/llvm/llvm-project/pull/139584, this is
problematic. This PR uses `std::shared_ptr` to reference-count
`ModuleCache` instead, which clarifies what happens to its lifetime when
constructing `CompilerInstance`, for example. This also makes the
reference in `ModuleManager` non-owning, simplifying the ownership
relationship further. The
`ASTUnit::transferASTDataFromCompilerInstance()` function now accounts
for that by taking care to keep it alive.

[clang-doc] Make sidebar sections collapsible (#174531)
Collapsible lists are achieved via `<details>` and their child
`<summary>` tags. `<details>` tags allow for a section to be designated
as collapsible, while the `<summary>` tag is used as the sidebar
section's header. This approach was chosen over making the lists
stateful through various CSS properties.
This patch also refactors the `<li>` tag structure of sidebar sections.
Previously, the section header and list items were in separate `<li>`
tags without sharing a parent. Now, the header and items are under a
single `<li>` tag which makes more sense semantically.

This patch resolves an issue where C23 fixed-underlying enum constants
were incorrectly treated as the underlying integer type instead of the
enumeration type.
According to C23 `6.7.2.2p15`:
> The enumeration member type of an enumerated type with a fixed
underlying type is the same as the type itself.

[llvm][formatters] Add LLDB data-formatter for llvm::PointerIntPair (#173261)
Depends on:
* https://github.com/llvm/llvm-project/pull/173238
(only last commit relevant for review)
This patch revives the `llvm::PointerIntPair` LLDB data-formatter. The
previous version was commented out because it relied on expression
evaluation and was hence slow/brittle. The formatter in this PR doesn't
rely on evaluating expressions.
Drive-by change:
* removes the `llvm::PointerUnion` formatter which was also commented
out. A future version of it will look very different than it does now,
so there's no point in keeping it because the diff won't be helpful in a
review.

[lldb] Update LLDB DAP documentation. (#172580)
This adds a new page to lldb.llvm.org that includes a user guide for
lldb-dap.
The overall structure for documentation:
* https://lldb.llvm.org/resources/lldbdap.html - represents the user
facing documentation for lldb-dap, a high level overview of lldb-dap and
a place we can point users to for basic usage information.
* https://lldb.llvm.org/resources/lldbdap-contributing.html - represents
the contributing documentation for lldb-dap.
* llvm-project/lldb/tools/lldb-dap/README.md - The lldb-dap VSCode
Extension specific documentation.
This is a first pass at the documentation, I expect to expand on it
further as needed.

If we did not pair two viable `Xqcilsm` load/store instructions in
`RISCVLoadStoreOptimizer` we iterated over the second instruction when
looking for other pairs to merge. This leads to us missing out on
opportunities where the second instruction could have been the start of
another potential pair that could have been merged.

Conservatively predicate sdiv/srem:
- RHS may carry poison in masked‑off lanes.
- RHS could be −1 while LHS has masked‑off lanes (risking INT_MIN/−1
overflow).
We’ll relax this once we can prove non‑wrap/non‑poison conditions.
Fixes #170775.

[clang-doc] Add a border box to comments in HTML (#174541)
Comments weren't very visually distinctive in HTML. They immediately
proceeded the declaration header and didn't have spacing between them.
To visually organize them, they now have a thin border around them.
Different comment types are also now separated by a small gap. This also
allows them to be easily changed in the future. Some extraneous `<div>`
tags are also removed or merged.

[libc++][NFC] Refactor `[[nodiscard]]` tests (#173451)
Originally some `[[nodiscard]]` tests were implemented in
`*/test/libcxx/diagnostics`. The Standard has a library `Diagnostics`
and this folder should be reserved for it by convention. Most newer
tests were added to their respective sub-folders. This patch moves
around the already implemented `[[nodiscard]]` tests to their respective
folders where they belong and standardizes the name to
`nodiscard.verify.cpp` wherever possible.
N.B. This refactors only tests, which were merged. The remaining
(in-progress) ones will be moved in a future patch to reduce merge
conflicts.

[RISCV][llvm-readobj,llvm-objdump] Use getRISCVVendorRelocationTypeName for RISCV vendor relocations (#172811)
Use getRISCVVendorRelocationTypeName to resolve RISCV vendor-specific
relocation names (R_RISCV_CUSTOM192-255) when preceded by
R_RISCV_VENDOR.
This improves the output of llvm-readobj and llvm-objdump to show
vendor-specific names like R_RISCV_QC_ABS20_U, R_RISCV_QC_E_BRANCH
(QUALCOMM) and R_RISCV_NDS_BRANCH_10 (ANDES) instead of generic
R_RISCV_CUSTOM* names.
Per RISC-V psABI, R_RISCV_VENDOR must be placed immediately before its
associated vendor-specific relocation, so the vendor symbol is consumed
after one use. Unknown vendors fall back to R_RISCV_CUSTOM*.

[ELF] Add VersionNode lexer state for better version script parsing
... so that `local:*;` will be lexed as three tokens instead of a single
one in a version node. This is used by both version scripts and dynamic
lists. Fix #174363
In addition, clean up special code for space-separated `local :` and `global :`.
This patch brings our lexer behavior closer to GNU ld. While GNU ld
additionally rejects more characters like `~/+,=`, we don't implement
this additional validation.

[mlir] Fix crash in dropRedundantArguments with produced operands. (#172759)
dropRedundantArguments was incorrectly indexing into forwardedOperands
using the block argument index directly. This crashes when the block has
produced operands (generated by the terminator, not forwarded from
predecessors) because forwardedOperands doesn't include them.
The fix checks isOperandProduced() to skip produced arguments and uses
SuccessorOperands::operator[] which handles the offset correctly.

[MLIR][Python] Forward the name of MLIR types to Python side (#174700)
In this PR, I added a C API for each (upstream) MLIR type to retrieve
its type name (for example, `IntegerType` -> `mlirIntegerTypeGetName()`
-> `"builtin.integer"`), and exposed a corresponding `type_name` class
attribute in the Python bindings (e.g., `IntegerType.type_name` ->
`"builtin.integer"`). This can be used in various places to avoid
hard-coded strings, such as eliminating the manual string in
`irdl.base("!builtin.integer")`.
Note that parts of this PR (mainly mechanical changes) were produced via
GitHub Copilot and GPT-5.2. I have manually reviewed the changes and
verified them with tests to ensure correctness.

[Buildbot][Polly] Move polly-x86_64-linux-test-suite build instructions into main repository (#166809)
Allow the main llvm-project repository to contain the buildbot builder
instructions, instead of storing them in llvm-zorg. The corresponding
llvm-zorg PR is https://github.com/llvm/llvm-zorg/pull/648.
Using polly-x86_64-linux-test-suite as a proof-of-concept because that
builder is currently offline, I am its maintainer, and is easier to
build than an configuration supporting offload. Once the design has been
decided, more builders can follow.
Advantages are:
* It is easier to make changes in the llvm-project repository. There are
more reviewers than for the llvm-zorg repository.
* Buildbot changes can be made in the same PR with changes that require
updating the buildbot, e.g. changing the name of a CMake option.
* Configuration changes take effect immeditately when landing; no
buildbot master restart needed.
* Some builders store a CMake cache file in the llvm-project repository
for the reasons above. However, the number of changes that can be made
with a CMake cache file alone are limited.
Compared to AnnotatedBuilder, advantages are:
* Reproducing a buildbot configuration locally made easy: just execute
the script in-place. No llvm-zorg, local buildbot worker, or buildbot
master needed.
* Same for testing a change of a builder before landing it in llvm-zorg.
Doing so with an AnnotatedBuilder requires two llvm-zorg checkouts:
One for making the change of the builder script itself, which then is
pushed to a private llvm-zorg branch on GitHub, and a second that is
modified to fetch that branch instead of
https://github.com/llvm/llvm-zorg/tree/main.
* The AnnotatedBuilder scripts are located in the llvm-zorg repository
and the buildbot-workers always checkout is always the top-of-trunk.
This means that a buildbot configuration is split over three checkouts:
* The checkout of llvm-project to be tested
* The checkout of llvm-zorg by the buildbot-worker fetches; always the
top-of-trunk, i.e may not match the revision of llvm-project that is
executed (such as the CMake cache files located there), especially when
using the "Force build" feature.
* The checkout of llvm-zorg that the buildbot-master is running, which
is updated only when the master is manually restarted.
* The "Force Build" feature also allows for test-building any
llvm-project PR. This is correctly handled by zorg's
`addGetSourcecodeSteps`, but does not work with AnnotatedBuilders that
checkout the llvm-project source on their own.
The goal is to move as much as possible into the llvm-project repository
such that there cannot be a mismatch between checkouts of different
repositories. Ideally, the buildbot-master only needs to be
updated+restarted for adding/removing workers, not for build
configuration changes.

Reapply [ConstantInt] Disable implicit truncation in ConstantInt::get() (#171456)
Reapply after additional fixes.
-----
Disable implicit truncation in the ConstantInt constructor by default.
This means that it needs to be passed a signed/unsigned (depending on
the IsSigned flag) value matching the bit width.
The intention is to prevent the recurring bug where people write
something like `ConstantInt::get(Ty, -1)`, and this "works" until `Ty`
is larger than 64-bit and then the value is incorrect due to missing
type extension.
This is the continuation of
https://github.com/llvm/llvm-project/pull/112670, which originally
allowed implicit truncation in this constructor to reduce initial scope
of the change.

[Clang] prevent assertion failure by avoiding always-dependent lambdas in constraint-related nested scopes (#173776)
Fixes #172814
---
This patch resolves an issue in which a lambda could be classified as
always-dependent while traversing nested scopes, causing an assertion
failure during capture handling.
Changes in PR #93206 expanded scope-based dependency handling in a way
that could mark certain lambdas as always-dependent when no
template-dependent context was present.
This update refines the criteria for assigning
`LambdaDependencyKind::LDK_AlwaysDependent` and applies it only after
traversal reaches a distinct enclosing function scope with
template-dependent parameters.

[Delinearization] Remove `isKnownLessThan` (#171821)
Delinearization has `isKnownLessThan(a, b)` function to check if `a < b`
is known at compile time. To check the predicate, it calls
`isKnownNegative(a - b)`. There are at least two issues with this
approach:
- It mixed up a signed interpretation with an unsigned one.
- It doesn't consider overflow.
This function includes some additional logic, which suffers from the
same issues. This patch replace the call to `isKnownLessThan(a, b)` with
`ScalarEvolution::isKnownPredicate(ICmpInst::ICMP_SLT, a, b)` and
removes the former function entirely, since using it is risky and may
lead to incorrect results.

[AArch64][NFC] Fix label checks on ZCM tests (#173482)
Previous checks were dead code. Now we share single `ALL-LABEL` checks

`--match-full-lines` which is needed by itself because the previous
versions of these tests suffered from false positives due to partial

Fix lifetime safety analysis for pointer dereference operations by

Added support in `FactsGenerator::VisitUnaryOperator()` to handle the
dereference operator (`UO_Deref`). This change ensures that when a
pointer is dereferenced, the origin of the pointer is properly
propagated to the dereference expression.

Fixes https://github.com/llvm/llvm-project/issues/172893.
In the issue reported above there, it appears that LLDB is hitting a 3s
timeout as part of some CI tests; this patch attempts to fix the issue
by replacing the 3s timeout with a 60s timeout, which should be suitably
long for any CI job (lldb-dap itself will automatically time out after
30s, so this should not be hit unless the process hangs).

[mlir][Transforms] `remove-dead-values`: Rely on canonicalizer for region simplification (#173505)
This commit simplifies the `remove-dead-values` pass and fixes a bug in
the handling of `RegionBranchOpInterface` ops. The pass used to produce
invalid IR ("null value found") for the newly added test case.
`remove-dead-values` is a pass for additional IR simplification that
cannot be performed by the canonicalizer pass. Based on a liveness
analysis, it erases dead values / IR. (The liveness analysis is a
dataflow analysis that has more information about the IR than a
canonicalization pattern, which can see only "local" information.)
Region-based ops are difficult. The liveness analysis may determine that
an SSA value is dead. However, that does not mean that the value can
actually be removed. Doing so may violate an region data flow (as
modeled by the `RegionBranchOpInterface`). As an example, consider the
case where a region branch terminator may dispatch to one of two region
successor with the same forwarded values. A successor input (block
argument) can be erased only if it is dead on both successors.
Before this commit, there used to be complex logic to determine when it
is safe to erase an SSA value. That logic was broken. The new
implementation does not remove any block arguments or op results of
region-based ops. Instead, operands of region-based ops and region
branch terminators are replaced with `ub.poison` if all of their
successor values are dead. This simplifies the IR good enough for the
canonicalizer to perform the remaining region simplification (i.e.,
dropping block arguments etc.).

[libclc] Initial support for cross-compiling OpenCL libraries (#174022)
Summary:
The other GPU enabled libraries, (openmp, flang-rt, compiler-rt, libc,
libcxx, libcxx-abi) all support builds through a runtime cross-build. In
these builds we use a separate CMake build that cross-compiles to a
single target.
This patch provides basic support for this with the `libclc` libraries.
Changes include adding support for the more standard GPU compute triples
(amdgcn-amd-amdhsa, nvptx64-nvidia-cuda) and building only one target in
this mode.
Some things left to do:
This patch does not change the compiler invocations, this method would
allow us to use standard CMake routines but this keeps it minimal.
The prebuild support is questionable and doesn't fit into this scheme
because it's a host executable, I'm ignoring it for now.
The installed location should just use the triple with no `libclc/`
subdirectory handling I believe.

to
handle non-constant (dynamic) indices. When a dynamic index is
encountered, the
vector is spilled to the stack, and the element is accessed via
OpAccessChain
(lowered from spv_gep).
This patch also adds custom legalization for G_STORE to scalarize vector
stores
and refines the legalization rules for G_LOAD, G_STORE, and
G_BUILD_VECTOR.

[MLIR][Python] Forward the name of MLIR attrs to Python side (#174756)
This PR is quite similiar to #174700.
In this PR, I added a C API for each (upstream) MLIR attributes to
retrieve its name (for example, `StringAttr -> mlirStringAttrGetName()
-> "builtin.string"`), and exposed a corresponding type_name class
attribute in the Python bindings (e.g., `StringAttr.attr_name ->
"builtin.string"`). This can be used in various places to avoid
hard-coded strings, such as eliminating the manual string in
`irdl.base("#builtin.string")`.
Note that parts of this PR (mainly mechanical changes) were produced via
GitHub Copilot and GPT-5.2. I have manually reviewed the changes and
verified them with tests to ensure correctness.

[lldb] Add zlib to version -v output (#174753)
I know this is required for at least one feature, because
TestSectionAPI.py has failures if zlib isn't enabled. So I think it's
useful for users to be able to check.
Now that it's in the config, I have also used it to make a test
annotation so we don't get the failure in TestSectionAPI.py when zlib is
disabled.
Which for future reference was:

[lldb][Format] Introduce a `FormatEntity::Formatter` class and move the `Format` API into it (#174618)
This patch creates a new `FormatEntity::Formatter` class and moves
`FormatEntity::Format` (and related APIs) into it. Most of the
parameters to `Format` are immutable across all recursive calls, so I
made them `const` member variables of `Formatter`. The main changes are
just mechanical renaming of:
```
FormatEntity::Format(...)
```
to
```
FormatEntity::Formatter(...).Format(stream, entry, valobj)
```
and making use of the member variables from inside `Format`.
We can probably make most of the parameters to the `Formatter`
constructor defaulted, but I chose not to in this patch to keep the diff
smaller.
The motivation for this is that I'm planning on adding logic to detect
recursive format entities (which would crash LLDB). That requires some
state, which in my opinion is best kept inside the `Formatter` class
instead of another parameter to `Format`.
The patch should be entirely NFC.

[cross-project-tests] Unset _FORTIFY_SOURCE when building the LLDB formatter tests (#174770)
When building `cross-project-tests` with `_FORTIFY_SOURCE` set, we get
following warnings:
```

```
This patch works around this by undefining the macro when compiling the
LLDB formatter tests.
If this ever becomes an issue we could try to detect `_FORTIFY_SOURCE`
and skip the tests if set.

[HLSL][Matrix] Implement dynamic single subscript swizzle (#173201)
fixes #170777
If we don't use vector type and instead continue to pass on the matrix
type when we enter `EmitExtVectorElementExpr` Then we don't need to
store the row and column length on the LValue.
Using the Matrix type means we can reuse the isMatrixRow() cases in
EmitLoadOfLValue and EmitStoreThroughLValue and not have to support a
new lValue that is a hybrid between the ExtVectorElt and MatrixRow
cases.
All we need to do to support this is pass the list of column indices as
a `ConstantDataVector` and check the size of this Vector to know how
many column iterations we need to do. Further just index into the vector
to fetch the right encoded element index value.

[SPIRV] Add legalization pass for zero-size arrays (#172367)
This adds a legalization pass to convert zero size arrays to legal types
for common cases. It doesn't handle all cases, but if we see real use
cases for other cases, we can add them in the future.
For globals, and their initializers, we generally replace `[0 x T]` with
`ptr`.
For instructions, we either replace `[0 x T]` with `poision`, for
`alloca` we just allocate `T`.
This is motivated by IR generated by the OpenMP front end.

[mlir][OpenMP] Lower device clause for target data/enter/exit/update (#174665)
Extend OpenMP device clause lowering for target data, target enter data,
target exit data, and target update to accept non-constant values.
Previously, only constant device IDs could be lowered to LLVM IR.
Add Flang tests to validate device clause handling and mark the feature
as supported in the OpenMPSupport documentation. New tests cover:
- target teams
- target teams distribute
- target teams distribute parallel do
- target teams distribute parallel do simd
- target data
Tests for target update and target enter/exit were
already present in Flang.

[mlir][py] ability to downcast AffineExpr after #172892 (#174808)
AffineExpr is a separate hierarchy of LLVM-style nested classes that
doesn't rely on TypeID and is not extensible. We need the ability to
downcast the Python equivalent of those to a specific subclass that was
seemingly lost in PR #172892. Bring it back by having an explicit cast.
We don't really need user-defined type casters here since AffineExpr is
entirely closed and not typed, unlike values.

[cross-project-tests][formatters] Add a LIT feature that tests for a compatible LLDB version (#174812)
Most of this logic is similar to how we add the
`gdb-clang-incompatibility` attribute.
Some LLVM LLDB formatters will rely on LLDB features not available in
older versions of LLDB. This feature will allow those tests to add a
`REQUIRES: lldb-formatters-compatibility`, which will then mark the test
`UNSUPPORTED` for incompatible LLDB versions. I picked `19.0` pretty
arbitrarily based on when approximately the
`SBType::FindDirectNestedType` API was added to LLDB (which a future
formatter will require).

Reland "[llvm][formatters] Add LLDB data-formatter for llvm::PointerIntPair"
Reverts a4cc033408fe0a69aad6865ddc7e020d64098f20.
Relanding the original patch as-is, but changing the `__builtin_debugtrap`s to explicitly set breakpoints. Some bots failed to compile the tests when `__builtin_debugtrap` was used.
Also adding `REQUIRES: lldb-formats-compatibility` to the test because some build-bots run the tests with an LLDB version that doesn't support the `FindDirectNestedType` API.
Original commit message:
This patch revives the llvm::PointerIntPair LLDB data-formatter. The previous version was commented out because it relied on expression evaluation and was hence slow/brittle. The formatter in this PR doesn't rely on evaluating expressions.
Drive-by change:
* removes the llvm::PointerUnion formatter which was also commented out. A future version of it will look very different than it does now, so there's no point in keeping it because the diff won't be helpful in a review.

[offload][lit] XFAIL all failing tests on the Level Zero plugin (#174804)
We finally got our buildbot added (to staging, at least) so we want to
start running L0 tests in CI.
We need `check-offload` to pass though, so XFAIL everything failing.
There's a couple `UNSUPPORTED` as well, those are for sporadic fails.
Also make set the `gpu` and `intelgpu` LIT variables when testing the
`spirv64-intel` triple.
We have no DeviceRTL yet so basically everything fails, but we manage to
get
```
Total Discovered Tests: 432
Unsupported : 169 (39.12%)
Passed : 67 (15.51%)
Expectedly Failed: 196 (45.37%)
```
We still don't build the level zero plugin by default and these tests
don't run unless the plugin was built, so this has no effect on most
builds.

The current (and default) backend on z/OS is EBCDIC.
This patch updates the default backend to be ASCII, which is beneficial
when porting new languages. With this change, ASCII is the default when
no special metadata nodes (such as `zos_le_char_mode`) are present.

[Clang] [Lexer] Detect SSE4.2 availability at runtime in fastParseASCIIIdentifier (#171914)
This change attempts to maximize usage of the SSE fast path in
`fastParseASCIIIdentifier`.
If compiling for x86, we compile both the SSE fast path and the scalar loop. At
runtime, we check if SSE4.2 is available and dispatch to the right
function by using the `target` attribute. If it _is_ available, this
allows a net performance improvement. Otherwise, there's a very slight
but negligible regression... I believe that's perfectly reasonable for a
non-SSE4.2-supporting processor.
If we are not compiling for x86, then the behavior is the exact same, ensuring we have
no regressions. If the binary is compiled for x86 with SSE4.2 enabled, we still do a runtime check, but this has negligible impact ; furthermore, the point of the PR is that this is rarely the case.
The benchmark results are available at
[llvm-compile-time-tracker](https://llvm-compile-time-tracker.com/compare.php?from=f88d060c4176d17df56587a083944637ca865cb3&to=d5485438edd460892bf210916827e0d92fc24065&stat=instructions%3Au).

This caused a similar crash during `DXILIntrinsicExpansion` as reported
here:
https://github.com/llvm/llvm-project/pull/171456#issuecomment-3718690088.
This change fixes the test case from crashing in the DirectX backend by
manually specifying it as a signed integer.

[VPlan] Add specialized VPValue subclasses for different types (NFC) (#172758)
This patch adds VPValue sub-classes for the different cases we currently
have:
* VPIRValue: A live-in VPValue that wraps an underlying IR value
* VPSymbolicValue: A symbolic VPValue not tied to an underlying value,
e.g. the vector trip count or VF VPValues
* VPRecipeValue: A VPValue defined by a VPDef/VPRecipeBase.
This has multiple benefits:
* clearer constructors for each kind of VPValue
* limited scope: for example allows moving VPDef member to VPRecipeValue,
reducing size of other VPValues.
* stricter type checking for member variables (e.g. using VPLiveIn in
the Value -> live-in map in VPlan, or using VPSymbolicValue for symbolic
member VPValues)
There probably are additional opportunities for cleanups as follow-ups.

[clang-doc] Add a breadcrumb navigation bar (#173297)
This patch adds a breadcrumb navigation bar to the `<navbar>` element. Now, you can navigate between the different scopes of a record or namespace. This is done by keeping track of a Decl's parent Decl through its USR. That allows us to traverse the set of `Info`s through a directed graph during JSON generation to create `Context`s. A context is just a `Reference` that holds a relative path to a scope's file from a particular `Info`.

This extends the CastOp folder to handle integral casts between

This is in preparation for a change that will attempt to fold casts as
they are generated, but this change only performs the folding via the
cir-canonicalize pass.

[lldb][TypeSystemClang] Set access specifier for EnumConstantDecl's (#174865)
LLDB was already setting the access specifier on `EnumDecl`s
unconditionally to `AS_public`. But it wasn't doing so for the
`EnumConstantDecl`s. This triggered a Clang assertion during
auto-completion of expressions
(https://github.com/llvm/llvm-project/issues/171913).
Ideally the code-completion accessibility check would honor the
`AccessControl` language option, but that change is harder to
test/justify. Since this is a pretty straight-forward change I want to
land this before trying to do that.
There is no test coverage for this because it relies on the order in
which Clang decides to check the decls in scope for auto-completion,
which seems fragile. It's also consistent with how we handle access to
other decls in `TypeSystemClang`.

[flang] Added LoopInvariantCodeMotion pass for [HL]FIR. (#173438)
The new pass allows hoisting some `fir.load` operations early
in MLIR. For example, many descriptor load might be hoisted
out of the loops, though it does not make much difference
in performance, because LLVM is able to optimize such loads
(which are lowered as `llvm.memcpy` into temporary descriptors),
given that proper TBAA information is generated by Flang.
Further hoisting improvements are possible in [HL]FIR LICM,
e.g. getting proper mod-ref results for Fortran runtime calls
may allow hoisting loads from global variables, which LLVM
cannot do due to lack of alias information.
This patch also contains improvements for FIR mod-ref analysis:
We may recurse into `HasRecursiveMemoryEffects` operations and
use `getModRef` recursively to get more precise results for
regions with `fir.call` operations.
This patch also modifies `AliasAnalysis` to set the instantiation
point for cases where the tracked data is accessed through a load
from `!fir.ref<!fir.box<>>`: without this change the mod-ref
analysis was not able to recognize user pointer/allocatable variables.

[WebAssembly] Support v128.load{32,64}_zero for f32 and f64 types (#172291)
This patch extends the `load_zero` pattern matching to
support floating-point vector types (`v4f32` and `v2f64`).
Previously, the optimization to generate `v128.load32_zero` and
`v128.load64_zero` was only enabled for integer types
(`v4i32` and `v2i64`). This change adds the necessary TableGen
patterns to correctly match scalar floating-point loads inserted
into zero-initialized vectors.

[IR] Fix canReplacePointersIfEqual to properly validate vector pointers (#174142)
Previously, `canReplacePointersIfEqual` unconditionally returned
`true` for vectors of pointers (e.g., `<2 x ptr>`) because it only
checked for scalar pointer types.
This resulted in a failure to perform appropriate verification for
these types. This patch fixes the logic to ensure they are properly
validated.

[WebAssembly] Fold constant `i8x16.swizzle` and `i8x16.relaxed.swizzle` to `shufflevector` (#169110)
Resolves #169058.
This adds ~~an InstCombine pass~~ a TTI hook to the WebAssembly backend
that folds `i8x16.swizzle` and `i8x16.relaxed.swizzle` operations to
`shufflevector` operations if their mask operands are constant.
This is mainly useful for abstractions over the raw intrinsics--for
instance, in architecture-generic SIMD code that may not be able to
expose the constant shuffles due to type system limitations.
I took most of this from the x86 backend (in particular,
`simplifyX86vpermilvar` in `X86InstCombineIntrinsic`), and adapted it
for the WebAssembly backend. There wasn't any previous
`instCombineIntrinsic` method on the WebAssembly `TargetTransformInfo`,
so I added it. Right now, this swizzle optimization is the only one it
performs.
As I noted in the transform itself, the "relaxed" swizzle actually has
stricter preconditions than the non-relaxed one. If a non-negative but
still out-of-bounds index is provided, the "relaxed" swizzle can choose
between returning 0 and the lane at the index modulo 16. However, it
must make the same choice every time, and we don't know which choice the
runtime will make, so we can't constant-fold it.
The regression tests were mostly generated by Claude and adapted a bit
by me (I tried to follow the [InstCombine contributor
guide](https://llvm.org/docs/InstCombineContributorGuide.html#tests)).
There was previously no WebAssembly subdirectory within the InstCombine
tests, so I created that too; as of now, the swizzle fold test is the
only file in it. Everything else was written by myself (well, partly
copy-pasted from the x86 backend).
I'm not sure how to write an Alive2 test for this; I can't find any
examples where the input is an arbitrary constant.

[SPIRV] Handle aggregate arguments to `spv_store` (#172348)
This patch handles the special case where an extract value yields an
aggregate result, which then is used as an argument to a store. The
SPIRV BE uses special intrinsics (`spv_extractv` and `spv_store`) to
represent these through IRTranslator, however this creates a problem:
`spv_store` is called as a function, and IRTranslator cannot handle
arguments that take more than a vreg. For other functions, the aggregate
argument replacement pass would have solved things, but it does not
apply here. Hence, we apply the same mutate-into-Int32 solution here
when dealing with stores, and restore the extract value's type (which we
have available as a ValueAttr) during instruction selection.

[mlir][Linalg] Drop unit extent dim in non-trivial expressions (#173873)
The current implementation does not drop unit extent dimension if that
dimension is indexed by a non-trivial affine expression (i.e., not a
single dimension or constant 0) on the first application of the
transformation. However, it is possible to drop such dimensions if all
dimensions involved in the affine expression are going to be dropped. So
far, this required repeated application of the transformation, with the
changes in this PR, the dimensions are dropped with a single application
of the transformation.

[RISCV] Generate Xqcilsm multi-word load/store instructions for three or more words (#174789)
This patch adds support for generating the `Xqcilsm` multi-word
load/store instructions for three or more words. We add a new function
in the `RISCVLoadStoreOptimizer` pass for doing this separate from the
one that does load store pairing. The reason for this is that the
implementation currently only looks for consecutive loads and stores to
merge where as the pairing logic has no such restriction. We also only
traverse the basic block top down for now while looking for instructions
to merge.

[lldb][TypeSystemClang] Fix nullptr check when creating enumerator decls
There is no point in checking the `enumerator_decl` because it was just created with `CreateDeserialized` above (which would only fail if allocation failed, but we don't do those checks usually). We dereference it unconditionally above this check anyway.
What this intended to check was probably `enum_decl`, because we derefernce it for the first time right after the check. This patch changes the nullptr check to `enum_decl`.
No test coverage because this should be pretty uncontroversial.
Note, I just saw this while auditing the code, I didn't actually run into a crash.

[libc++] Optimize search_n (#171389)
This changes the algorithm to more efficiently skip ranges which cannot
match the needle for random access iterators. Specifically, we now
search for a mismatching element from the back of the subrange we want
to check. When a mismatch occurs we can directly start one after the
mismatched element, since there cannot possibly be a matching subrange
starting between the start of the subrange we checked and the mismatched
element (since all elements have to be equal). The algorithm also
remembers the subrange which was already match as being equal and
doesn't try to compare it a second time, reducing the time spent in case
of a match.

[Mips] Add MipsPat `(MipsGPRel tglobaladdr:$in)` to select MipsISD::GPRel TargetGlobalAddress (#165531)
The original logic:
```
SelectionDAG has 17 nodes:
t0: ch,glue = EntryToken
t2: i64,ch = CopyFromReg t0, Register:i64 %0
t11: i32 = truncate t2
t14: i32 = and t11, Constant:i32<1>
t20: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str.1> 0 [TF=3]
t21: i64 = add Register:i64 $gp_64, t20
t16: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str> 0 [TF=3]
t18: i64 = add Register:i64 $gp_64, t16
t7: i64 = select t14, t21, t18
```
When SelectionDAG process visitSELECT, would fold select(cond,
binop(x, y), binop(x, z)) to binop(x, select(cond, y, z)).
As follows:
```
SelectionDAG has 16 nodes:
t0: ch,glue = EntryToken
t2: i64,ch = CopyFromReg t0, Register:i64 %0
t11: i32 = truncate t2
t14: i32 = and t11, Constant:i32<1>
t20: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str.1> 0 [TF=3]
t16: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str> 0 [TF=3]
t22: i64 = select t14, t20, t16
t23: i64 = add Register:i64 $gp_64, t22
```
Therefore, the original MipsPat `add GPR64:$gp, (MipsGPRel
tglobaladdr:$in)` is no longer available. And there would be an assert:
```
ISEL: Starting selection on root node: t20: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str.1> 0 [TF=3]
ISEL: Starting pattern match
Initial Opcode index to 0
Match failed at index 0
LLVM ERROR: Cannot select: t20: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str.1> 0 [TF=3]
```
So we add a new MipsPat `def : MipsPat<(MipsGPRel tglobaladdr:$in),
(DADDiu ZERO_64, tglobaladdr:$in)>, ISA_MIPS3, ABI_N64;`
to parse MipsISD::GPRel TargetGlobalAddress.
Fix #142060.

[AArch64] Fold scalar-to-vector shuffles into DUP/FMOV (#166962)
Previously, LLVM emitted inefficient instructions when the low lanes of
a 128-bit vector were set to a scalar and high bits set to 0. This patch
utilises instructions fmov/dup to set the low lanes to the necessary
scalar and zeroes the high bits of the register.
E.g. in its worse case,
```
int8x16_t foo_s8(int8_t a) {
int8x16_t b = vcombine_s8(vdup_n_s8(a), vdup_n_s8(0));
return b;
}
```
LLVM would emit:
```
foo_s8(signed char):
movi v0.2d, #0000000000000000
mov v0.b[0], w0
mov v0.b[1], w0
mov v0.b[2], w0
mov v0.b[3], w0
mov v0.b[4], w0
mov v0.b[5], w0
mov v0.b[6], w0
mov v0.b[7], w0
ret
```
This patch now emits:
- <2 x i64> from i64 -> fmov d0, x0
- <4 x i32> from i32 -> dup v0.2s, w0
- <8 x i16> from i16 -> dup v0.4h, w0
- <16 x i8> from i8 -> dup v0.8b, w0

[Clang][Modules] Emit C++20 BMIs to working directory with -fmodule-output (#174560)
Close #173689.
When -fmodule-output is specified without an explicit path, Clang
currently emits the generated .pcm next to the source file. This
contradicts the documentation and breaks out-of-tree builds.
This patch updates the fallback behavior to emit the BMI in the working
directory, instead of the source file directory.
Driver tests are updated accordingly. Explicit -fmodule-output=PATH
behavior is unchanged.

[mlir][OpenMP] Translation support for taskloop construct (#174386)
This PR replaces #166903
This implements translation for taskloop, along with DSA clauses. Other
clauses will follow immediately after this is merged.
This patch was collaborative work by myself, @kaviya2510, and
@Stylie777. I’ve left the commits unsquashed to make authorship clear.
My only changes to other author’s commits are to rebase and run
clang-format.
The taskloop implementation in the runtime works roughly like this: if
the number of loop iterations to perform are more than some threshold,
the current task is duplicated and both resulting tasks gets half of the
loop range. This continues recursively until each task has a small
enough loop range to run itself in a single thread.
This leads to two implementation complexities:
- The runtime needs to be able to update the loop bounds used when
executing the loop inside of the task. This has been implemented by
forcing them to always have a fixed location inside of the structure
produced when outlining the task.
- When a task is duplicated, all data stored for the task’s
(first)private variables needs to also be duplicated and appropriate
constructors run. This is handled by a task duplication function invoked
by the runtime.
With regards to testing, most existing tests in the gfortran and fujitsu
test suites require the reduction clause (not part of OpenMP 4.5). I
wrote some tests of my own and was satisfied that it seems to be
working.

[libc++] Remove numpunct_byname::__init (#173283)
`numpunct_byname::__init` is only used inside the dylib, so we can
remove it. To do that we can move the code into one of the constructors
and delegate the other.

[LifetimeSafety] Add implicit tracking for STL functions (#170005)
Add support for tracking STL container methods and free functions in the
lifetime safety analysis.
- Added `VisitExprWithCleanups` to the `FactsGenerator` to properly
handle expressions with cleanup code
- Moved `shouldTrackImplicitObjectArg` and `shouldTrackFirstArgument`
from `CheckExprLifetime.cpp` to `LifetimeAnnotations.h/cpp` to make them
available to the lifetime safety analysis
- Enhanced the lifetime analysis to track STL container methods that
return pointers or references dependent on the container's lifetime
(e.g., `begin()`, `data()`, `c_str()`)
- Added support for tracking free functions like `std::begin`,
`std::data`, and `std::any_cast` that return pointers or references
dependent on their arguments

[MLIR][Python] Add GreedyRewriteDriverConfig parameter to apply_patterns_and_fold_greedily (#174913)
We already have `GreedyRewriteDriverConfig` on the Python side, but it
hasn’t yet been exposed as a parameter of
`apply_patterns_and_fold_greedily`. This PR does that.
Before:
```python
def apply_patterns_and_fold_greedily(module: ir.Module, set: FrozenRewritePatternSet) -> None
def apply_patterns_and_fold_greedily(op: ir._OperationBase, set: FrozenRewritePatternSet) -> None
```
After:
```python
def apply_patterns_and_fold_greedily(module: ir.Module, set: FrozenRewritePatternSet,
config: GreedyRewriteDriverConfig | None = None) -> None
def apply_patterns_and_fold_greedily(op: ir._OperationBase, set: FrozenRewritePatternSet,
config: GreedyRewriteDriverConfig | None = None) -> None
```
Note this PR is adapted from
https://github.com/llvm/llvm-project/pull/174785 but using
`std::optional` instead of `nb::object`. Note, this required refactoring
`PyGreedyRewriteDriverConfig` to have a `std::shared_ptr` so that it
could support a copy-ctor.

[SPIRV] Support additional comparison predicates for i1 types (#174585)
Previously, the SPIRV BE only handled equality and inequality
comparisons (ICMP_EQ, ICMP_NE) for i1 types using logical operations
(OpLogicalEqual, OpLogicalNotEqual). Other comparison predicates
(signed/unsigned less than, greater than, etc.) triggered an unreachable
assertion.
This patch extends the support for the missing predicates. The BE
considers i1 values as booleans and in SPIR-V only logical operations
can work on them. This patch lowers the missing predicates into
supported logical operations.
The lowering has been validated with instcombine to avoid introducing an
unsound transformation (using the new test case).

If a block with an INLINEASM_BR instruction and any of its

[WebAssembly] Change `half` to use soft promotion rather than `PromoteFloat` (#152833)
The default `half` legalization, which Wasm currently uses, does not
respect IEEE conventions: for example, casting to bits may invoke a lossy
libcall, meaning soft float operations cannot be correctly implemented.
Change to the soft promotion legalization which passes `f16` as an `i16`
and treats each `half` operation as an individual
f16->f32->libcall->f32->f16 sequence.
Of note in the test updates are that `from_bits` and `to_bits` are now
libcall-free, and that chained operations now round back to `f16` after
each step.

[IRCE] Prove predicates with and without loop-guarded SCEVs (#174843)
IRCE may fail to prove predicates when loop bounds are rewritten by
LoopConstrainer::applyLoopGuards(). In such cases, simple predicates
(e.g. %start < %limit) become obscured by strengthened SCEV expressions,
even though they are trivially implied by the guard in the loop
preheader.
See: https://github.com/llvm/llvm-project/issues/167827
This change makes IRCE attempt to prove predicates both on the original
SCEVs and on the guarded SCEVs, preventing incorrect rejection of loops
with safe bounds.

[PowerPC] Change `half` to use soft promotion rather than `PromoteFloat` (#152632)
On PowerPC targets, `half` uses the default legalization of promoting to
a `f32`. However, this has some fundamental issues related to inability
to round trip. Resolve this by switching to the soft legalization, which
passes `f16` as an `i16`.
The PowerPC ABI Specification does not define a `_Float16` type, so the
calling convention changes are acceptable.

[SPIRV] Additional fixes for const init via `UtoPtr` (#172584)
#166494 added support for using `inttoptr` in global initialisation, and
lowering int into `OpSpecConstantOp OpConvertUToPtr`. Unfortunately, it
slightly more subtle case / exposed an existing issue around the `COPY`
pseudo-op. This patch ensures that we glance through a `COPY` when
figuring out whether an `OpConvertUToPtr` is actually operating on a
global. We also correctly handle the case where a `G_PTR_ADD` is used by
an `OpSpecConstantOp` in the context of global initialisation, which
would otherwise lead to broken SPIR-V wherein the latter would reference
a non constant Op.

[lldb][Format] Reject recursive format entities (#174750)
Depends on:
* https://github.com/llvm/llvm-project/pull/174618
If a format entity calls back into `Format` and passes it a format
entity type that we're already in the process of parsing, we are likely
going to run into infinite recursion and blow the stack. I think this is
only an issue when a format entity calls Format on a format string
provided by the user (otherwise we're in control of the recursion). An
example of this can be seen in the test-case adjusted by this patch.
This seems to be causing actual crashes in the field, so this patch adds
basic tracking to `Formatter::Format` that checks whether we're
recursively parsing the same entity. This may very well be intended by
some entities (e.g., `Root` and `Scope`), so there is an escape hatch
for those. There's also a special case where `Variable` causes a
recursive format (which I pointed out in a source comment).
We could narrow the scope of what kind of recursion is allowed by adding
a `UserProvidedFormatChild` (or similar) flag to `Entry`, and only
disallow recursing on those kinds of entries. For now I just use an
exemption list in `IsInvalidRecursiveFormat`.
Adding a unit-test for this is unfortunately tricky because the only
format entity that currently suffers from this is
`${function.name-with-args}`, which requires a language plugin and valid
target. If we really wanted to we could probably mock all of those, but
the shell test provides test coverage for the previously crashing case.

in another block in `GetValueInMiddleOfBlock`. If we erase it too early,
this can lead to a use-after-erase.

[SLP] Use ConstantInt::getSigned for stride argument to strided load/store intrinsics (#175007)
strided-stores-vectorized.ll crashes for RV32 without fixing the
relevant logic in vectorizeTree, because the argument can't be
represented as a 32-bit unsigned value:
```
llvm::APInt::APInt(unsigned int, uint64_t, bool, bool): Assertion `llvm::isUIntN(BitWidth, val) && "Value is not an N-bit unsigned value"' failed.
```
It is intended to be signed, so we simply use ConstantInt::getSigned
instead. This fixes other stride-related instances in the file as well.
For further context, this change is part of unblocking rv32gcv
llvm-test-suite in CI.

[llvm-c] Add LLVMParseIRInContext2 (#174085)
This new function is the same as LLVMParseIRInContext except it doesn't
take ownership of the memory buffer. This fixes a wart that has been in
place since 5ebb7b311223bcd21d2b3d25413d1edacefcc63d changed the
underlying internal API to avoid taking ownership.
Reduce nesting in the implementation of LLVMParseIRInContext (now
LLVMParseIRInContext2) as well.
Update examples, OCaml bindings, and tests including plugging some
pre-existing memory leaks. OCaml bindings have renamed `parse_ir` to
`parse_ir_bitcode_or_assembly` to provoke compilation failures in
downstream code; this is intentional as this function now requires the
memory buffer to be disposed by the caller.

[RISCV] Bail out of combineNarrowableShiftedLoad for types other than scalar int (#175011)
Introduced in #170483 this was only ever meant to trigger for scalar
types. We get an error on rv32gcv for some inputs "Cannot implicitly
convert a scalable size to a fixed-width size in `TypeSize::operator
ScalarTy()`".
While we're editing this function, delete an accidentally repeated
comment.
Minimal reproducer:
```
define <vscale x 4 x ptr> @ham() {
bb:
%load = load <vscale x 4 x i32>, ptr null, align 4
%ashr = ashr <vscale x 4 x i32> %load, splat (i32 1)
%getelementptr = getelementptr i32, ptr null, <vscale x 4 x i32> %ashr
ret <vscale x 4 x ptr> %getelementptr
}
```
Added without test as the fix is trivial and the test is rather awkward/specialised. We will get coverage for this and similar issues from llvm-test-suite rv32gcv in CI.

through 5. The prescanner presently emits only a warning for this case.
Retain the warning for -E output, but otherwise diagnose an error.
(This change affected a number of tests that relied on this situation
being a warning just so that they could test prescanner warnings, and
those tests were adjusted to use another warning.)

The previous PR #173096 assumes that format attribute parameters always
refer to valid indices of arguments. It is a wrong assumption in itself
because the second attribute parameter could specify the index after the
last named parameter for variadic functions and no actual arguments
passed beyond named parameters. In addition, clang (possibly
incorrectly) allows the following uses of the attribute:
```
void f(const char *) __attribute__((__format__ (__printf__, 1, 2))); // The second attribute argument 2 will not refer to any valid argument at any call of 'f'
void g(const char *) __attribute__((__format__ (__printf__, 1, 99))); // Clang is even quiet on this, if assertions are disabled :(

[RISCV] Mark More Relocs as Relaxable (#151422)
Since this code was last reviewed, more relaxations have been added to
the psABI for existing standard relocations that LLVM didn't have marked
as relaxable.
This change ensures that LLVM marks the following relocations (and their
respective fixups) as relaxable:
- `R_RISCV_JAL`
- `R_RISCV_GOT_HI20`
- `R_RISCV_TPREL_HI20`
- `R_RISCV_TLSDESC_HI20`
This also updates the linker relaxation test to use `-NEXT` to check all
the output lines.
There are lots more emitted relocations, not only due to JAL being
relaxable, but branches are now also marked linker relaxable because
they can be turned into `b<cc>; jal` during assembly relaxation, which
may also be marked relaxable.

[mlir][python] Fail fast when nanobind is missing for Python bindings (#174649)
Remove problematic `return()` statements from
mlir_configure_python_dev_packages macro and convert nanobind detection
to FATAL_ERROR.
Using `return()` in a CMake macro is problematic because it returns from
the calling scope, not the macro itself, causing the parent
CMakeLists.txt to silently skip subsequent configuration steps. This
leads to confusing build failures when Python bindings are enabled but
nanobind is missing.
With this change, users get an immediate error with clear instructions
to install nanobind or set nanobind_DIR, rather than silent
configuration failures.

[SPIR-V] Add builtin/intrinsic for subgroup ballot (#174862)
Summary:
This patch adds an LLVM intrinsic and lowering for a subgroup ballot and
a corresponding clang builtin. This uses the already present support but
provides in a way accessible to other targets. With this and
https://github.com/llvm/llvm-project/pull/174655 we should be able to
most of the basic functions, like shuffling, active masks, and
reductions. More work will be needed for canonicalizing / exposing the
SPIR-V functions, but these are the fundamental builtins I need.

[AArch64] Add intra-block CSINC optimization to AArch64ConditionOptimizer (#173734)
This patch extends the AArch64ConditionOptimizer pass to handle CSINC
instructions within a single basic block, complementing the existing
cross-block branch optimization.
The optimization finds two CMP+CSINC pairs comparing the same register
with immediates differing by 1, and adjusts one comparison to enable CSE
to eliminate the redundant CMP instruction.
Example transformation:
```
cmp w8, #10
csinc w9, w0, w1, gt ; w9 = (w8 > 10) ? w0 : w1+1
cmp w8, #9 ; Removed by CSE after adjustment
csinc w10, w0, w1, gt ; w10 = (w8 > 9) ? w0 : w1+1
```
After optimization:
```
cmp w8, #10
csinc w9, w0, w1, gt ; w9 = (w8 > 10) ? w0 : w1+1
csinc w10, w0, w1, ge ; w10 = (w8 >= 10) ? w0 : w1+1
```
The existing cross-block logic has also been extracted into its own
method.
Any feedback on code quality and better practices is highly welcome.

Some tests are already supported on "remote" devices and simulators.
However, there is currently no way to distinguish a remote macOS host
from a local one.
This adds the darwin-remote feature which is common to all test targets
which use a wrapper script (e.g. iossim_run.py).

This change implements part of
https://discourse.llvm.org/t/rfc-lldb-make-pdbastbuilder-language-agnostic/89117,
the goal of which is make `PdbAstBuilder` language-agnostic.
It adds several new interface methods to `PdbAstBuilder` which allow
`SymbolFileNativePDB` to interact with it without using Clang-specific
types. These new methods would make up much of the interface of a future
abstract `PdbAstBuilder`. `SymbolFileNativePDB` is updated to use these.
The old Clang-specific methods were renamed if used by
`UdtRecordCompleter` or internally, or removed where possible.

A substring reference where the lower bound is higher than the upper

Thus, a reference to a substring of a CHARACTER*(0) string such as

foo().
We also should not error if the lbound > ubound at compile time.

The cause is that in `python3.14`, `fcntl.ioctl` now throws a buffer
overflow error
when the buffer is too small or too large (see
https://github.com/python/cpython/pull/132919). This caused the Python
interpreter to fail terminal detection and not properly echo user
commands back to the screen.
Fix by dropping the custom terminal size check entirely and using the
built-in `sys.stdin.isatty()` instead.

[mlir][acc] Add OffloadLiveInValueCanonicalization pass (#174671)
Introduce a pass to canonicalize live-in values for regions that will be
outlined for device execution.
When a region is outlined, values defined outside but used inside become
arguments to the outlined function. However, some values cannot or
should not be passed as arguments:
- Synthetic types (shape metadata, field indices)
- Constants better recreated inside the region
- Address-of operations for device-resident globals
This pass identifies such values and either sinks the defining operation
into the region (when all uses are inside) or clones it inside (when
uses exist both inside and outside).
To identify target regions in a dialect-agnostic way, this patch
introduces `OffloadRegionOpInterface`. This marker interface allows the
pass to work uniformly across OpenACC compute constructs, GPU
operations, and other offload dialects without hardcoding operation
types. The interface is attached to `acc.parallel`, `acc.kernels`, and
`acc.serial` directly through TableGen. It is also being attached to
`gpu.launch` and `cuf.kernel`, the latter through the FIR OpenACC
extensions.
The pass leverages existing interfaces for candidate detection:
`OutlineRematerializationOpInterface` marks operations producing
non-argument-passable values, while `ViewLikeOpInterface` and
`PartialEntityAccessOpInterface` allow tracing through casts and views
to find original defining operations. OpenACCSupport analysis provides
symbol validation for address-of operations.

[clang-tidy] Prefer the faster LLVM ADT sets and maps over `std::` ones (#174357)
The LLVM docs give a good description of [why `std::` containers are
slower than LLVM
alternatives](https://llvm.org/docs/ProgrammersManual.html#set). To see
what difference switching to the LLVM ones made, I [reused the
approach](https://github.com/llvm/llvm-project/pull/174237#issuecomment-3707395449)
of measuring how long it takes to run all checks over all standard
library headers (MSVC STL in my case). Using hyperfine (which basically
runs a program multiple times and computes how long it took):
```sh
hyperfine --shell=none './build/release/bin/clang-tidy --checks=* all_headers.cpp -header-filter=.* -system-headers -- -std=c++23'
```
...the results were:
Before:
```
Benchmark 1: ./build/release/bin/clang-tidy --checks=* all_headers.cpp -header-filter=.* -system-headers -- -std=c++23
Time (mean ± σ): 53.253 s ± 0.089 s [User: 46.480 s, System: 6.748 s]
Range (min … max): 53.118 s … 53.440 s 10 runs
```
After:
```txt
Benchmark 1: ./build/release/bin/clang-tidy --checks=* all_headers.cpp -header-filter=.* -system-headers -- -std=c++23
Time (mean ± σ): 51.798 s ± 0.126 s [User: 45.194 s, System: 6.575 s]
Range (min … max): 51.620 s … 51.995 s 10 runs
```
...which is a nice little speedup for just switching some containers. I
didn't investigate which checks in particular were the source of the
speedup though.

[InstCombine] Limit canonicalization of extractelement(cast) to constant index or same basic block (#166227)
The current canonicalization of extractelement(cast) requires that the
CastInst has only one use. However, when that use occurs inside a loop,
it still satisfies this condition, even though the cast is effectively
used multiple times, once per iteration, rather than truly being used
once.
```cpp
} else if (auto *CI = dyn_cast<CastInst>(I)) {
// Canonicalize extractelement(cast) -> cast(extractelement).
// Bitcasts can change the number of vector elements, and they cost
// nothing.
if (CI->hasOneUse() && (CI->getOpcode() != Instruction::BitCast)){
```
Before
```llvm
%34 = fptosi <4 x float> %33 to <4 x i32>
;/loop{
%40 = extractelement <4 x i32> %34, i32 %36
```
After
```llvm
;/loop{
%37 = extractelement <4 x float> %30, i32 %32
%38 = fptosi float %37 to i32
```
After canonicalization, for this particular example, it no longer uses a single instruction to cast the entire vector at once, but instead performs the cast for every element separately, which is less performant.
Ideally, we would like to check if the cast instruction **has one use and that this use is not called inside a loop**. However, InstCombine/InstCombineVectorOps.cpp does not provide utilities like `LoopInfo` to check that. It might be possible to approximate this by analyzing basic block successors or by building a dominance tree, but that may be a costly solution.
A solution to prevent this optimization could be to check if the index is an immediate value and if the use is inside the same basic block as the cast instruction:
```cpp
if (CI->hasOneUse() && (CI->getOpcode() != Instruction::BitCast)) {
Instruction *U = cast<Instruction>(*CI->user_begin());
if (U->getParent() == CI->getParent() || isa<ConstantInt>(Index)){
```

[CodeGen] Strip Coroutine suffixes when generating pseudo probe (#173834)
CoroSplit pass now creates separate DWARF symbols with the `.resume`,
`.destroy`, `.cleanup` suffixes.
https://github.com/llvm/llvm-project/pull/141889 But pseudo probes are
created in an earlier pass (`SampleProfileProbePass`) before the
CoroSplit, which creates a mismatch of Function GUIDs between the
original function name and the function names with the coroutine
suffixes during the CodeGen when the AsmPrinter iterates through the
`InlinedAt` chain and generates the `InlineStack`.
This will create mismatched pseudo probes in the final binary and
llvm-profgen will also fail when parsing the pseudo probe section. This
fix simply strips the coroutine suffixes from the inline callers' name,
so the CoroSplit changes will be transparent.

[SampleProf] Handle coro wrapper function name canonicalization (#174881)
Fix an issue where `FunctionSamples::getCanonicalFnName` incorrectly
canonicalizes coro await suspense wrapper functions to collide with the
coro function itself. This causes the sample annotation to skip coro
function. Canonicalization strips everything comes after the first dot
(.), unless the function attribute
"sample-profile-suffix-elision-policy" is set to "selected", in which
case it strips after the known suffixes. The wrapper function name has
the suffix of ".__await_suspend_wrapper__" + await_kind. Add the
attribute to wrapper function so that the suffix is not stripped.

[SPIR-V] Add clang builtin for subgroup shuffles (#174655)
Summary:
This is an attempt to begin filling out some missing pieces to allow
more generic compute code to use SPIR-V flavored builtins. This should
provide the basic shuffle operation. The next most important one is the
ballot, but I don't think we have an IR intrinsic for that yet.
I don't know SPIR-V very well so let me know if this is the proper
function with the proper semantic checks.

[SPIR-V] Add clang builtin for group-wide barrier (#175064)
Summary:
This adds a clang builtin for the existing group sync. I was considering
instead exposing a raw barrier operation and chaining it with a
`__scoped_atomic_thread_fence` but this seemed simpler. Right now this
implies a sequentially consistent memory fence. These semantics should
already match with what's implied with CUDA `__syncthreads`. I'm unsure
if there's a situation where we'd need more control. If we want more
control we'd probably just want to match it up with the scoped atomic
scopes.

Summary:
We already have a way to get the block count using the old grid size
lookup and dividing it by the number of threads. We did not want to make
a new intrinsic to do the same thing, so this optimization pattern
matches on this usage to automatically optimize it to the new form. This
should improve performance of old kernels by converting branches into a
simple index lookup and removing the division.

[lldb] Keep the unexpected b/p state for suspended threads (#174264)
This fixes stepping out for a case when two threads reach the
stepping-out target breakpoint simultaneously, but a concurrent thread
executes the breakpoint first. The issue affects platforms with software
breakpoints. The scenario is as follows:
* The `step-out` command is executed for thread `A`.
* `ThreadPlanStepOut` creates a breakpoint at the target location.
* All threads are resumed, because the `step-out` command does not
suspend other threads.
* Threads `A` and `B` reach the stepping-out address at the same time,
but `B` executes the breakpoint instruction first.
* `SetThreadStoppedAtUnexecutedBP()` is called for thread `A`, and
`SetThreadHitBreakpointSite()` is called for thread `B`.
* Thread `B` has no plans to stop at this location, so
`ThreadPlanStepOverBreakpoint` is scheduled.
* The plan disables the breakpoint and resumes thread `B` with
`eStateStepping`; for thread `A`, `ShouldResume(eStateSuspended)` is
called, which clears `m_stopped_at_unexecuted_bp`.
* After the stepping, `ThreadPlanStepOverBreakpoint` finishes, the
breakpoint is re-enabled, and all threads are resumed.
* At this moment, thread `A` is still at the location of the breakpoint,
but `m_stopped_at_unexecuted_bp` is cleared, so
`Thread::SetupToStepOverBreakpointIfNeeded()` schedules
`ThreadPlanStepOverBreakpoint` for it.
* `ThreadPlanStepOverBreakpoint` steps over the target breakpoint, so
`ThreadPlanStepOut` can't catch the execution there.

[ORC] Add JITDylibDefunct Error. (#174923)
This Error can be returned from operations on JITDylibs that cannot
proceed as the target JITDylib has been closed.
This patch uses the new error to replace an unsafe assertion in
JITDylib::define: If a JITDylib::define operation is run by an in-flight
task after the target JITDylib is closed it should error out rather than
asserting.

[SFrame][Retry] Add assembler option --gsframe (#165806)
This plumbs the option --gsframe through the various levels needed to
support it in the assembler.
This is the final step in assembler-level sframe support for x86. With
it in place, clang produces sframe-sections that successfully link with
gnu-ld.
LLD support is pending some discussion.
The previous PR (https://github.com/llvm/llvm-project/pull/165322) had a
bad merge, but the only comments were as below. Both done.
1. Fix some stray formatting.
2. Add tests that:
the option is passed on to cc1
the correct error is emitted when an unsupported platform is used
the assembler behaves as expected (even if this has been tested
elsewhere, an end-to-end "integration" test would be useful)
The test for assembler behavior simply checks that an sframe section is
added, and is modeled after the similar one for crel.

LocalStackSlotAllocation pass disallows negative offsets with respect to

frame references. This patch helps LocalStackSlotAlloca to additionally
consider the immediate offset of an instruction, when sorting frame refs
- hence, avoiding negative offsets and maximizing reuse of the existing
registers.

Commit

changed how frem is expanded during legalization and it
broke WebAssembly but we were missing test coverage. We want to maintain
our previous behavior of unrolling vectors and using a libcall to
implement scalar frem. I'm not sure why this now has to be different
(in ISelLowering) from other libcalls like fsin which work the same way
in the end, but this code does accurately describe what we want.

[ORC] Add utilities for limited symbolication of JIT backtraces (#175099)
This patch adds tools for capturing symbol information from JIT'd code
and using it to symbolicate backtraces. This is useful for debugging
crashes in JIT-compiled code where traditional symbolication tools may
not have access to the JIT symbol table. These tools are not a general
solution to the JIT symbolication problem (that will require further
integration with system components like libunwind, the dynamic linker,
and/or crash tracing tools), but will aid in JIT debugging and
development until a general solution is available.
APIs Added:
1. SymbolTableDumpPlugin - A LinkGraphLinkingLayer::Plugin that captures
symbol information as code is JIT'd and writes it to a file.
- Create(StringRef Path) ->
Expected<std::shared_ptr<SymbolTableDumpPlugin>> Creates a plugin that
appends symbol information to the specified file.
- Symbol table format: "<link graph name>" <address> <symbol name>
<address> <symbol name> ...
The plugin uses a PostAllocationPass to write symbols after addresses
have
been assigned but before the code is finalized.
2. DumpedSymbolTable - A class for symbolicating backtraces using a
previously dumped symbol table.
- Create(StringRef Path) -> Expected<DumpedSymbolTable> Loads and parses
a symbol table from a file.
- symbolicate(StringRef Backtrace) -> std::string Given text of a
backtrace, for rows ending with a hex address, adds the symbol name,
offset, and defining graph name.
New `llvm-jitlink` Command Line Options:
1. -write-symtab=<path> Enables the SymbolTableDumpPlugin to write
symbol information to the specified file as objects are JIT'd. The
symbol table can then be used to symbolicate backtraces from crashes or
signal handlers.
2. -symbolicate-with=<path> Runs llvm-jitlink in symbolication mode.
Reads the symbol table from <path> and symbolicates backtraces read from
stdin or input files.
Usage Examples:
$ llvm-jitlink -write-symtab=symbols.txt mycode.o
$ llvm-jitlink -symbolicate-with=symbols.txt - < backtrace.txt

* Adds some additional logging in the

is now emitted along the success path so we can see what the plugin
computed.
* `ComputeStopReasonAndSuggestedStackFrame` now logs if the debug info
vs no debug info path is taken.
* `CheckIfRuntimeIsValid` now prints the correct module path. Previously
it always printed `<unknown module>`.
* `Deactivate` now prints the breakpoint number correctly. Previously
this would try to print signed breakpoints IDs as unsigned. This problem
was observable because internal breakpoints use negative breakpoint IDs.

[llvm-jitlink] Replace IR backtrace symbolication testcase with asm. (#175117)
Some builds (e.g.
https://lab.llvm.org/buildbot/#/builders/154/builds/26180) failed for
this testcase, for reasons that aren't immediately clear from the logs.
Since the options being tested are for debugging only, this commit
switches to testing Darwin/arm64 only.
Whne similar backtrace symbolication options are added to lli we can
reintroduce a generic testcase and start investigating these failures.

Reapply "[llvm-exegesis] Add AArch64 operand initializers, SetRegTo" (#174729) (#174944)
This reverts commit f68774fd1ad570fef850439ac163b61dc96b98f1. The
original PR broke the sanitizer-aarch64-linux-bootstrap-asan builder:
https://lab.llvm.org/buildbot/#/builders/24/builds/16298
The cause of the failure was exegesis producing inconsistent results
across libc++ implementations when seeded with
'--random-generator-seed=<seed>'. The failing Buildbot does a 2-stage
build, in the 1st stage it builds LLVMs libc++ then builds LLVM with it
in the 2nd stage. The exegesis implementation relies on
uniform_int_distribution which doesn't guarantee consistent results
across implementations.
The tests seeded the RNG because FileCheck can't handle the wrap around
constraint of the register pairs, e.g. { v31.1d, v0.1d }. The test is
updated to no longer rely on '--random-generator-seed'. Unfortunately
the tests aren't particularly good anymore, but not sure what else can
be done for now.

[libc++] Correct `optional<T&>` implementation (#174537)
Resolves #174350
- Several issues were found in the current implementation of
`optional<T&>`
- `value()`, `operator*()`, `and_then()`, `transform()`, `operator->()`
still provided their ref-qualified versions for rvalues and `const&`.
- Using the listed methods on an rvalue `optional<T&>` would cause a
compile failure due to a mismatch in return types.
- On the latter, `operator*`, `operator->` would return `const` for a
`optional<T&>`, which is an incorrect deep const.
- A few constructors were missing (`optional<U>&`), and most
constructors relevant to `optional<T&>` were missing `noexcept`
- Constructors and `emplace` were not correctly constructing a `T&` as
specified in _`convert-ref-init-val`_
- Also corrects the behavior of `value_or` which should return
`remove_cv_t<T>` (in our case `decay_t<_Tp>`)
- Add several test cases to verify behavior, update `value_or` tests

[Clang] Let isAnyArgInstantiationDependent handle Null template arguments (#174698)
Unused template parameters, though never referenced during substitution,

The null type placeholder plays this role, while
isAnyArgInstantiationDependent() doesn't properly handle this case when
checking nested constraints.
There is no release note because this is a regression from concept
parameter mapping.

[AArch64] Optimize ANDS(CSET, CSET) to CCMP. (#174919)
We have existing optimizations for and(cset, cset) and or(cset, cset),
converting them to more optimal ccmp chains. This makes use of the same
optimization for ANDS instructions that do not require the result of the
AND (i.e. TSTs). We generate a cmp from a cset, for the flags produced
by the ANDS. This will then be optimised away in many cases, leaving the
ccmp and use of the flags.

[MLIR][OpenMP] Add Initial Taskloop Clause Support (#174623)
Following on from the work to implement MLIR -> LLVM IR Translation for
Taskloop, this adds support for the following clauses to be used
alongside taskloop:
- if
- grainsize
- num_tasks
- untied
- Nogroup
- Final
- Mergeable
- Priority
These clauses are ones which work directly through the relevant OpenMP
Runtime functions, so their information just needed collecting from the
relevant location and passing through to the appropriate runtime
function.
Remaining clauses retain their TODO message as they have not yet been
implemented.

operations like `_mm_ceil_sd` compile to suboptimal assembly:
```asm
roundsd xmm1, xmm1, 10
blendpd xmm0, xmm1, 1
```
This PR introduces a rewrite pattern to mitigate this, and fuse the corresponding operations.

[AArch64] Fix using NEON copies in streaming-mode-enable regions. (#174738)
The current checks for if we're allowed to use a NEON copy works based on
the function attributes, which works most of the time. However in one
particular case where a normal function calls a streaming one, there's a
window of time where we enable SM at the call site and the emit a copy for
an outgoing parameter. This copy was lowered to a NEON move which is illegal.
There's also another case where we could end up generating these,
related to zero cycle move tuning features.
Both of these cases is fixed in this patch by walking back from the copy
to look for any streaming mode changes (within the current block). I know
this is pretty ugly but I don't have a better solution right now.

[libc++] Introduce the notion of a minimum header version (#166074)
Introducing the notion of a minimum header version has multiple
benefits. It allows us to merge a bunch of ABI macros into a single one.
This makes configuring the library significantly easier, since, for a
stable ABI, you only need to know which version you started distributing
the library with, instead of checking which ABI flags have been
introduced at what point. For platforms which have a moving window of
the minimum version a program has been compiled against, this also makes
it simple to remove symbols from the dylib when they can't be used by
any program anymore.

preconditions, resulting in us rejecting valid code.
This also significantly improves performance for `deque` in some cases.

Currently `_LIBCPP_OVERRIDABLE_FUNCTION` takes the return type, function
name and argument list, but simply constructs the function and adds
attributes without modifying the signature in any way. We can replace
this with a normal attribute macro, making the signature easier to read
and simpler to understand what's actually going on. Since it's an
internal macro we can also drop the `_LIBCPP_` prefix.

Fix lld crash using --fix-cortex-a53-843419 (#170495)
Original crash was observed in Chromium, in [1]. The problem occurs in
elf::isAArch64BTILandingPad because it didn't handle synthetic sections,
which can have a nullptr as a buf, so it crashed while trying to read
that buf.
After fixing that, a second issue occurs: When the patched code grows
too
much, it gets far away from the short jump, and the current
implementation
assumes a R_AARCH64_JUMP26 will be enough.
This PR changes the implementation to:
(a) In isAArch64BTILandingPad, checks if a section is synthetic, and
assumes that it'll NOT contain a landing pad, avoiding the buffer check;
(b) Suppress the size rounding for thunks that preceeds section
(Making the situation less likely to happen);
(c) Reimplements the patch by using a R_AARCH64_ABS64 in case the
patched code is still far away.

[CodeGen] Generalise Hexagon flags for memop inline thresholds (#172829)
Generalise the Hexagon cmdline options to control if memset, memcpy or memmove intrinsics should be inlined versus calling library functions, so they can be used by all backends:
• -max-store-memset
• -max-store-memcpy
• -max-store-memmove
These flags override the target-specific defaults set in TargetLowering (e.g., MaxStoresPerMemcpy) and allow fine-tuning of the inlining threshold for performance analysis and optimization.
The optsize variants (-max-store-memset-Os, -max-store-memcpy-Os, max-store-memmove-Os) from the Hexagon backend were removed, and now the above options control both.
The threshold is specified as a number of store operations, which is backend-specific. Operations requiring more stores than the threshold will call the corresponding library function instead of being inlined.

[flang] Fix homonymous interface and procedure warning (#171696)
When emitting an homonymous generic interface and procedure warning,
the source locations of the interface and the procedure were being
compared to find the one that occurred later in the source file.
The problem is that they could be in different source/module files,
which makes the comparison invalid.
Fix it by using parser::AllCookedSources::Precedes() instead, that
correctly handle names in different source files.

[MLIR][NVVM] Fix crash on invalid optimization level in NVVMTargetAttr (#173280)
Update `NVVMTargetAttr` builder in `NVVMOps.td` to use `$_get` instead
of `Base::get`.
Now the auto-generated parser calls `getChecked`, allowing graceful
error handling for invalid parameters (e.g., `O=4`) instead of crashing
with an assertion failure.
Add a regression test in
`mlir/test/Dialect/LLVMIR/nvvm-target-invalid.mlir`.

[AllocToken] Fix attribute mismatch in AllocTokenPass (#174959)
Fixes an attribute mismatch error in `AllocTokenPass` that occurs during
ThinLTO builds at OptimizationLevel::O0.
The `getTokenAllocFunction` in `AllocTokenPass` was incorrectly copying
attributes from the instrumented function (`Callee`) to an *existing*
`void()` alloc-token function retrieved by `Mod.getOrInsertFunction`.
This resulted in arg attributes being added to a function with no
parameters, causing `VerifyPass` to fail with "Attribute after last
parameter!".
The fix modifies `getTokenAllocFunction` to pass the `Callee`'s
attributes directly to the `Mod.getOrInsertFunction` overload. This
ensures attributes are only applied when the alloc-token function is
*newly inserted*, preventing unintended attribute modifications on
already existing function declarations.
See https://g-issues.chromium.org/issues/474289092 for detailed
reproduction steps and analysis.

[flang][OpenMP] Prevent `omp.map.info` ops with user-defined mappers from being marked as parial maps (#175133)
The following test was triggering a runtime crash **on the host before
launching the kernel**:
```fortran
program test_omp_target_map_bug_v5
implicit none
type nested_type
real, allocatable :: alloc_field(:)
end type nested_type
type nesting_type
integer :: int_field
type(nested_type) :: derived_field
end type nesting_type
type(nesting_type) :: config
allocate(config%derived_field%alloc_field(1))
!$OMP TARGET ENTER DATA MAP(TO:config, config%derived_field%alloc_field)
!$OMP TARGET
config%derived_field%alloc_field(1) = 1.0
!$OMP END TARGET
deallocate(config%derived_field%alloc_field)
end program test_omp_target_map_bug_v5
```
In particular, the runtime was producing a segmentation fault when the
test is compiled with any optimization level > 0; if you compile with
-O0 the sample ran fine.
After debugging the runtime, it turned out the crash was happening at
the point where the runtime calls the default mapper emitted by the
compiler for `nesting_type; in particular at this point in the runtime:
https://github.com/llvm/llvm-project/blob/c62cd2877cc25a0d708ad22a70c2a57590449c4d/offload/libomptarget/omptarget.cpp#L307.
Bisecting the optimization pipeline using `-mllvm -opt-bisect-limit=N`,
the first pass that triggered the issue on `O1` was the `instcombine`
pass. Debugging this further, the issue narrows down to canonicalizing
`getelementptr` instructions from using struct types (in this case the
`nesting_type` in the sample above) to using addressing bytes (`i8`). In
particular, in `O0`, you would see something like this:
```llvm
define internal void @.omp_mapper._QQFnesting_type_omp_default_mapper(ptr noundef %0, ptr noundef %1, ptr noundef %2, i64 noundef %3, i64 noundef %4, ptr noundef %5) #6 {
entry:
%6 = udiv exact i64 %3, 56
%7 = getelementptr %_QFTnesting_type, ptr %2, i64 %6
....
}
```
```llvm
define internal void @.omp_mapper._QQFnesting_type_omp_default_mapper(ptr noundef %0, ptr noundef %1, ptr noundef %2, i64 noundef %3, i64 noundef %4, ptr noundef %5) #6 {
entry:
%6 = getelementptr i8, ptr %2, i64 %3
....
}
```
The `udiv exact` instruction emitted by the OMP IR Builder (see:
https://github.com/llvm/llvm-project/blob/c62cd2877cc25a0d708ad22a70c2a57590449c4d/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#L9154)
allows `instcombine` to assume that `%3` is divisible by the struct size
(here `56`) and, therefore, replaces the result of the division with
direct GEP on `i8` rather than the struct type.
However, the runtime was calling
`@.omp_mapper._QQFnesting_type_omp_default_mapper` not with `56` (the
proper struct size) but with `48`!
Debugging this further, I found that the size of `omp.map.info`
operation to which the default mapper is attached computes the value of
`48` because we set the map to partial (see:
https://github.com/llvm/llvm-project/blob/c62cd2877cc25a0d708ad22a70c2a57590449c4d/flang/lib/Optimizer/OpenMP/MapInfoFinalization.cpp#L1146
and
https://github.com/llvm/llvm-project/blob/c62cd2877cc25a0d708ad22a70c2a57590449c4d/mlir/lib/Target/LLVMIR/Dialect/OpenMP/OpenMPToLLVMIRTranslation.cpp#L4501-L4512).
However, I think this is incorrect since the emitted mapper (and
user-defined mappers in general) are defined on the whole struct type
and should never be marked as partial. Hence, the fix in this PR.

[CommandLine] Use DenseMap instead of StringMap (NFC) (#174988)
StringMap duplicates the option name to a new allocation for every
option, which is not necessary. Instead we can use the same StringRef
that the Option already uses inside a DenseMap. This reduces the amount
of allocations when loading libLLVM.

[clang][CodeGen] Fix ConstantInt::get for i1 in EmitScalarPrePostIncDec (#175152)
In ScalarExprEmitter::EmitScalarPrePostIncDec we create ConstantInt
values that are either 1 or -1. There is a special case when the type is
i1 (e.g. for unsigned _BitInt(1)) when we need to be able to create a
"i1 true" value for both inc and dec.
To avoid triggering the assertions added by the pull request #171456 we
now treat the ConstantInt as unsigned for increments and as signed for
decrements.

[SPIR-V] Initial support for SPIR-V in `gpuintrin.h` (#174910)
Summary:
https://github.com/llvm/llvm-project/pull/174862 and
https://github.com/llvm/llvm-project/pull/174655 provided the intrinsics
required to get the fundamental operations working for these. This patch
sets up the basic support (as far as I know).
This should be the first step towards allowing SPIR-V to build things
like the LLVM libc and the OpenMP Device Runtime Library. The
implementations here are intentionally inefficient, such as not using
the dedicated SPIR-V opcode for read firstlane. This is just to start
and hopefully start testing things later.
Would appreciate someone more familiar with the backend double-checking
these.

[LLD][COFF] Prefetch inputs early-on to improve link times (#169224)
This PR reduces outliers in terms of runtime performance, by asking the
OS to prefetch memory-mapped input files in advance, as early as
possible. I have implemented the Linux aspect, however I have only
tested this on Windows 11 version 24H2, with an active security stack
enabled. The machine is a AMD Threadripper PRO 3975WX 32c/64t with 128
GB of RAM and Samsung 990 PRO SSD.
I have used a Unreal Engine-based game to profile the link times. Here's
a quick summary of the input data:
```
Summary
--------------------------------------------------------------------------------
4,169 Input OBJ files (expanded from all cmd-line inputs)
26,325,429,114 Size of all consumed OBJ files (non-lazy), in bytes
9 PDB type server dependencies
0 Precomp OBJ dependencies
350,516,212 Input debug type records
18,146,407,324 Size of all input debug type records, in bytes
15,709,427 Merged TPI records
4,747,187 Merged IPI records
56,408 Output PDB strings
23,410,278 Global symbol records
45,482,231 Module symbol records
1,584,608 Public symbol records
```
In normal conditions - meanning all the pages are already in RAM - this
PR has no noticeable effect:
```

However when in production conditions, we're typically working with the
Unreal Engine Editor, with exteral DCC tools like Maya, Houdini; we have
several instances of Visual Studio open, VSCode with Rust analyzer, etc.
All this means that between code change iterations, most of the input
OBJs files might have been already evicted from the Windows RAM cache.
Consequently, in the following test, I've simulated the worst case
condition by evicting all data from RAM with
[RAMMap64](https://learn.microsoft.com/en-us/sysinternals/downloads/rammap)
(ie. `RAMMap64.exe -E[wsmt0]` with a 5-sec sleep at the end to ensure
the System thread actually has time to evict the pages)

[OpenMP] Remove testing LTO variant on CPU targets (#175187)
Summary:
This is only really meaningful for the NVPTX target. Not all build
environments support host LTO and these are redundant tests, just clean
this up and make it run faster.

[ConstantFolding] Allow truncation when folding wasm.dot
Changes this to getSigned() to match the signedness of the calculation.
However, we still need to allow truncation because the addition
result may overflow, and the operation is specified to truncate
in that case.
Fixes https://github.com/llvm/llvm-project/issues/175159.

[InstCombine] Fold intrinsics over multi-use selects when the intrinsic is the only user (#172723)
Closes #172176.
Previously, `FoldOpIntoSelect` wouldn't fold multi-use selects if
`MultiUse` wasn't explicitly true. This prevents useful folding when the
select is used multiple times in the same intrinsic call. Similar to
what is done in `foldOpIntoPhi`, we'll now check that all of the uses
come from a single user, rather than checking that there is only one
use.

This isn't NFC because using an immediate directly will call
computeKnownBits to fill in bits that are expected to be 1, but have
been cleared because they are known 0 in the LHS of the and. We don't
have tests for this, if it's important we can switch to a ComplexPattern
to restore that behavior.

emitting the case statements. This will help reduce the memory footprint
by not storing potentially long strings (for opcode names) in the map.

XCOFF associated metadata (#159096)
Add a new metadata node `!implicit.ref` to represent an implicit
dependency between 2 symbols. The metadata is unique to AIX and gets
lowered to a relocation that adds an explicit link between the section
the global that the metadata is placed on is allocated in, to the
asscoiated symbol. This relocation will cause the associated symbol to
remain live if the section is not garbage collected. This is used mainly
for compiler features where there is some hidden runtime dependency
between the symbols that isn't otherwise obvious to the linker.

argument to `process attach` is effectively ignored. This patch makes it
so that "gdb-remote" remains the default, while still honoring the
process plugin name specified in the attach info. The same thing applies
to launching a process.

[SPIR-V] Permit implicit conversion to generic AS (#175109)
Summary:
We rely on this in most places we work with address spaces. This allows
target address spaces to implicity convert to generic ones.
I actually have no clue if this is valid or correct with SPIR-V, hoping
someone with more target / backend knowledge can chime in.

[flang][cuda] Avoid inserting GetDeviceAddress call in offload regions (#175225)
In regions destined for GPU offload, computing an address_of means
getting device address directly - no need (and actually incorrect) to
insert a runtime call to get the address. This was already working for
regions such as `gpu.launch` - but now it applies to acc regions as
well.

[lldb] fix a problem in the ValueObject::GetExpressionPath method (#171521)
Consider the following program:
```
int main() {
int foo[2][3][4];
int (*bar)[3][4] = foo;
return 0;
}
```
If we:
- compile this program
- launch an LLDB debugging session
- launch the process and let it stop at the `return 0;` statement
then the following LLDB command:
```
(lldb) script lldb.frame.FindVariable("bar").GetChildAtIndex(0).get_expr_path()
```
will produce the following output:
```
bar->[0]
```
What we were expecting:
- a valid expression in the C programming language
- that would allow us (in the scope of the `main` function) access the
appropriate object.
What we've got is a string that does not represent a valid expression in
the C programming language.
This pull-request proposes a fix to this problem.

The encoding scheme for 48-bit and larger instructions has not

proposal that included 4 reserved major opcodes. LLVM's
disassembler implements this proposal as does binutils.
A vendor extension might have used the reserved opcodes,
as a non-conforming 32-bit extension. Try to decode as a
32-bit instruction first to catch these cases.
Should help with #174571.

[HLSL][Sema] Validate that occupied register numbers never exceed UINT32_MAX (#174028)
This PR adds validation for register numbers.
Register numbers ought never to exceed UINT32_MAX, or 4294967295
Additionally, resource arrays will have each resource element bound
sequentially, and those resource's register numbers should not exceed
UINT32_MAX, or 4294967295. Even though not explicitly given a register
number, their effective register number is also validated.
This accounts for nested resource declarations and resource arrays too.

[lldb] Fix TestMultithreaded.py when libc++ symbols are present (#174664)
There are a few test cases in TestMultithreaded.py. Most of them set a
breakpoint by name on "next". There's no problem with doing that, but
one of the tests cases in particular relies on being able to grab a
specific breakpoint location corresponding to the test inferior.
If you have libc++ symbols, this test will also have breakpoint
locations for symbols named `next` in libc++. I could have changed the
test to find the correct `next` breakpoint location, but it seems easier
to give it a more uncommon name instead.

[Clang][DebugInfo] Add a flag to use expansion loc for macro params.
This patch adds a flag to allow users to preserve the old behaviour -
use the macro expansion location for parameters. This is useful for
wider testing of sample profile driven PGO which relies on debug
information based mapping. This flag is intended to be temporary
and should be safe to remove by EOY 2026. Filed #175249 to
track the cleanup.

then the second lane index (1) will be out of bounds of what a signed

unsigned.
The test case come from tensorflow/XLA.

[OpenMP] Preserve the original address when `use_device_ptr/addr` lookup fails. (#174659)
As per OpenMP 5.1, we need to assume that when the lookup for
`use_device_ptr/addr` fails, the incoming pointer was already device
accessible.
Prior to 5.1, a lookup-failure meant a user-error (for
`use_device_ptr`),
so we could do anything in that scenario. For `use_device_addr`,
it was always incorrect to set the address to null.
OpenMP 6.1 adds a way to retain the previous behavior of nullifying a
pointer
when the lookup fails. That will be tackled by the PR stack
starting with https://github.com/llvm/llvm-project/pull/169603.

[clang-doc] Move navbar and sidebar into normal document flow (#175110)
The navbar and sidebar caused spacing and alignment issues since they
were fixed elements with defined height/width. It was difficult to have
all elements below them correctly offset the height. This patch changes
them
to sticky elements within the normal document flow that don't define
their
height/width explicitly. This actually lets us use existing HTML/CSS
properties (like the "content" div) more naturally.
This also changes the navbar behavior to not follow while scrolling.

[Coverage] Make additional counters available for BranchRegion. NFC. (#120930)
`getBranchCounterPair()` allocates an additional Counter to SkipPath in
`SingleByteCoverage`.
`IsCounterEqual()` calculates the comparison with rewinding counter
replacements.
`NumRegionCounters` is updated to take additional counters in account.
`incrementProfileCounter()` has a few additiona arguments.
- `UseSkipPath=true`, to specify setting counters for SkipPath. It
assumes `UseSkipPath=false` is used together.
- `UseBoth` may be specified for marking another path. It introduces the
same effect as issueing `markStmtAsUsed(!SkipPath, S)`.
`llvm-cov` discovers counters in `FalseCount` to allocate `MaxCounterID`
for empty profile data.

This patch changes the deferred worklist to store pairs of (index, kind)

worklist processing logic is updated to resolve the correct entry type.

LLVMCoverage: Unify getCoverageForFile and getCoverageForFunction. NFC (#120842)
Since #119952, `getCoverageForFile` and `getCoverageForFunction` have
similar structure each other. Ther merged method `addFunctionRegions`
has two lambda subfunctions.
* `getCoverageForFile`
- `MainFileID` may be `nullopt`.
- `shouldProcess` picks up relevant records along `FileIDs` that is
scanned based on `MainFileID`. They may have expanded source files.
- `shouldExpand` takes the presense of `MainFileID` into account.
* `getCoverageForFunction`
- This assumes the presense of `MainFileID`.
- `shouldProcess` picks up records that belong only to `MainFileID`.
- `shouldExpand` assumes the presense of `MainFileID`.
This change introduces a wrapper class `MergeableCoverageData` for
further merging instances. At the moment, this returns `CoverageData`
including `buildSegments()`.
This change itself is NFC.

Thread Safety Analysis: Add test for guarded member initialization pattern in C (#175267)
A common problem in C code with guarded members is object construction,
where it should be allowed to initialize guarded members without holding
a capability (which itself requires initialization).
One potential pattern to solve this is "init with reentrant assert"
followed by member initialization. The pattern assumes that capability
objects themselves have an init function, which then asserts the
capability as held. To permit immediate use of the capability, we have
to cast to any reentrant capability.
The current implementation of reentrant capability supports this pattern
as-is: Casting to ReentrantMutex works because the analysis determines
if a held lock is reentrant based on the type used when the lock was
added to the fact set. Since the assertion uses the reentrant type, the
analysis records that the lock is reentrant. When the subsequent
mutex_exclusive_lock() occurs, the analyzer checks the properties of the
already held lock; finding it marked as reentrant, it allows the
"re-acquisition" instead of flagging a double-lock error.
Despite the potential for false negatives (real double-lock), the
pattern requires explicit casting to an auxiliary reentrant capability,
so this is not something that can easily happen by accident, but rather
requires developer intent and deliberate use. This is a valid solution
to this problem encountered by the Linux kernel:

[MC/DC] Refactor MCDC::State::Decision. NFC. (#125408)
Introduce `ID` and `InvalidID`. Then `DecisionByStmt` can have three
states.
* Not assigned if the Stmt(Expr) doesn't exist.
* When `DecisionByStmt[Expr]` exists:
* Invalid and should be ignored if `ID == Invalid`.
* Valid if `ID != Invalid`. Other member will be filled in the Mapper.

[SDAG] Add freeze when simplifying select with undef arms (#175199)
Consider the following pattern:
```
%trunc = trunc nuw i64 %x to i48
%sel = select i1 %cmp, i48 %trunc, i48 undef
```
We cannot simplify `%sel` to `%trunc` as `%trunc` may be poison, which
cannot be refined into undef.
This patch checks whether the replacement may be poison. If so, it will
insert a freeze.
We may need SDAG's version of `impliesPoison` if it causes significant
regressions.

[MLIR][SCF] Fix Loop Trip Count Calculation for Unsigned Values (#175301)
Previously, loop trip count was calculated using signed division
and remainder for both signed and unsigned values.
For loops like:
```
scf.for unsigned 0 to -100 step 2147483647 : i32 {}
```
This resulted in a trip count of 1 when the actual trip count is 2.
This PR fixes it by using unsigned division and remainder for
unsigned values.

[lldb-dap] Add clipboard context support (#170644)
This patch introduces support for `clipboard` context from
[DAP](https://microsoft.github.io/debug-adapter-protocol/specification#Types_Capabilities).
This feature is very useful when you want to copy all nested values from
a structure or a container instead of a summary (e.g. `size = 3` for
vector). I added new short mode for description generation to reduce
output verbosity, which is particularly useful for primitive types.

[X86][SDAG] Fix shamt for vXi8 shift expansion (#175308)
The bailing-out logic for 3-stage shifts acts as follows:
```
if (MinLZ < 2) {
conditionally shift by 4
}
if (MinLZ < 1) {
conditionally shift by 2
}
conditionally shift by 1
```
When `MinLZ = 1`, only the shift by 4 and by 1 paths are executed. It is
weird.
Closes https://github.com/llvm/llvm-project/issues/175303. The original
reproducer is equivalent to the existing func `@shl2_v32i8`, so no new
tests need to be added.

[VPlan] Allow truncation for lanes in VPScalarIVStepsRecipe (#175268)
VPScalarIVStepsRecipe relies on APInt truncation in order to vectorize
blocks with a width greater than the maximum value the types of some of
their (changing) operands are able to hold (e.g., an i1 input with a
vector width of 4). Simply reenable implicit truncation in
ConstantInt::get() to cover this case.
Remove the helper function given it is only called in one place to
prevent accidentally using it elsewhere where we probably do not want
implicit truncation turned on.
This fixes another case that we saw after
acb78bde6fb613a9af2a604bc69fa744a8cee850 did not fix that issue, which
had the same stack trace. We still want to keep lane constants as
unsigned.
Somewhat similar to 6d1e7d4982fabc9e245897056a5425496df6a7a3.
This test case comes from a tensorflow/XLA compilation from a test case
in https://github.com/google-research/spherical-cnn.

[MLIR][Python] Register `OpAttributeMap` as `Mapping` for `match` compatibility (#174292)
This is a continuation of the idea from #174091 to add `match` support
for MLIR containers. In this PR the `OpAttributeMap` container is
registered as a `Mapping`, so be mapped as a "dictionary" in `match`
statements.
For this to work the `get(key, default=None)` method had to be
implemented. Those are pretty much copys of `dunderGetItemNamed` and
`dunderGetItemIndexed` with an added argument and `nb::object` as return
type, because they can now return other types than just `PyAttribute`.
Was unsure if I should refactor this to make `dunderGetItem...` use the
new `getWithDefault...` or if a separate method is preferred. Kept it as
a copy for simplicitys sake for now.
Even though the `OpAttributeMap` supports indexing by `int` and `str`,
Python does not allow to register it as a `Sequence` and a `Mapping` at
the same time. If it is registered as a Sequence it only returns the
attribute names as string, not as `NamedAttribute`. It is technically
possible to also use integer keys for the `dict`-like match, but it
doesn't provide any constraints on the number of attributes, etc., so
probably not recommended.
<details><summary>Example</summary>
```python
from mlir.ir import Context, Module, OpAttributeMap
from collections.abc import Sequence
ctx = Context()
ctx.allow_unregistered_dialects = True
module = Module.parse(
r"""
"some.op"() { some.attribute = 1 : i8,
other.attribute = 3.0,
dependent = "text" } : () -> ()
""",
ctx,
)
op = module.body.operations[0]
def test(attr):
match attr:
case [*args]:
print("matched a Sequence", args)
case _:
print("Didn't match as Sequence")
match attr:
case {"some.attribute": a, "other.attribute": b, "dependent": c}:
print("Matched as Mapping individually", a, b, c)
case _:
print("Didn't match a Mapping")
match attr:
case {0: a, 1: b}:
print("Matched as Mapping with 2 int keys", a, b)
case _:
print("Didn't match as Mapping with 2 int keys")
print("Registered as Mapping only:")
test(op.attributes)
print("\nAfter additonally registering as Sequence:")
Sequence.register(OpAttributeMap)
test(op.attributes)
```
Output:
```
Registered as Mapping only:
Didn't match as Sequence
Matched as Mapping individually 1 : i8 3.000000e+00 : f64 "text"
Matched as Mapping with 2 int keys NamedAttribute(dependent="text") NamedAttribute(other.attribute=3.000000e+00 : f64)
After additonally registering as Sequence:
matched a Sequence ['dependent', 'other.attribute', 'some.attribute']
Didn't match a Mapping
Didn't match as Mapping with 2 int keys
```

Control spacing for attribute printing (#174197)
This was motivated by the decl printing for the alignas() keyword
attribute:
class alignas(1) Foo;
would be printed as:
class alignas(1) Foo;
with two spaces before class name.
Rather than trying to help `prettyPrintAttributes` guess what the caller
wants in terms of leading and trailing spaces, have it return an
`optional<string>` which is either the pretty-printed attributes for
Pos,
or `nullopt` if no attributes were found.
That way callers can compose and only print desired prefix/suffix if
they know there are attributes to print.
Add simple test cases for alignas.

[clang] Add a valid begin source location for abbreviated function templates (#174723)
The begin source location for function templates is determined by the
source location of the template keyword.
Pure abbreviated function templates do not have the template keyword.
This results in an invalid begin source location for abbreviated
function templates.
Without a valid begin source location, comments cannot be attached to
the function template which leads to the bug described in
clangd/clangd#2565.
This patch introduces new begin locations for abbreviated function
templates (begin of the templated function) and generic lambdas (begin
of the introducer `[...]`) when creating the template parameter lists in
Sema.

[clang-format] Correctly annotate C compound literal braces (#173771)
Fixes https://github.com/llvm/llvm-project/issues/173583
clang-format mis-formats C compound literals used in macro bodies, e.g.
`#define getAddr(v, type) &(type){v}`, treating `{...}` as a
block/function body
and reflowing the macro with backslashes and spaces.
This change:
- Recognizes `&( ... ){ ... }` patterns in macro bodies and marks the
brace as a braced-init.
- Improves parsing stability for braced lists in macro bodies.
Tests:
- FormatTests

Since this type was only added a few days ago

[mlir] Remove loop peeling explicit C'tor (#175419)
The SCF dialect loop peeling pass has an explicit C'tor. This creates an
inconvenience to use non default pass options, since they can only be
passed as a string after the pass creation. After removing the explicit
C'tor, the code auto generation creates 2 C'tors, which one of them can
directly receive pass options struct in case non default values are
required.
The explicit C'tor does not match auto generated C'tor convention, so
this change requires any uses of the pass in downstream projects to
update to use the auto generated C'tor.

[mlir][Interfaces][NFC] Document that `RegionBranchTerminatorOpInterface` is mandatory (#174978)
Document that implementing the `RegionBranchTerminatorOpInterface` is
mandatory. Omitting this interface on a block terminator that models
region branching may lead to invalid/incomplete analyses and
transformations.
This commit does not change the op/interface semantics. It just puts in
writing an assumption that is made throughout the code base. For
example:
- It is baked into the API design of the `RegionBranchOpInterface`. You
cannot query the region successors of block terminators that do not
implement the `RegionBranchTerminatorOpInterface`:
`RegionBranchOpInterface::getSuccessors()` takes a `RegionBranchPoint`
parameter, and such region branch points can be constructed only from
`RegionBranchTerminatorOpInterface` and not arbitrary `Operation *`.
- Helper functions + default interface method implementations enumerate
region branch points by looking for `RegionBranchTerminatorOpInterface`
and ignoring other operations. E.g.,
`RegionBranchOpInterface::getAllRegionBranchPoints`, default
implementation of `RegionBranchOpInterface::getSuccessorRegions(Region
&)`, default implementation of
`RegionBranchOpInterface::getPredecessorValues`.
- Core analyses such as `DeadCodeAnalysis` look for
`RegionBranchTerminatorOpInterface` and misbehave when the interface is
not implemented. The analysis does not (and cannot) query region
successors of a region branching terminator that does not implement the
`RegionBranchTerminatorOpInterface`. In practice, this means that
forgetting to implement the `RegionBranchTerminatorOpInterface` may
incorrectly classify regions as dead.
- Other analyses / transformations that look for and depend on the
implementation of `RegionBranchTerminatorOpInterface`:
`mlir::getControlFlowPredecessors`,
`AbstractDenseBackwardDataFlowAnalysis`, ownership-based buffer
deallocation pass.

[UTC] Align label var handling of old lines to new lines (#173850)
BB labels have been treated as variables in newer UTC versions.
However, UTC previously handled BB labels in old lines differently from
new lines, causing incorrect `remap_metavar_names`.
E.g.,
- New lines var `exit:` and `label %exit`: UTC generalized them as
`[[@@]]` and `[[@@]]`.
- Old lines var `[[EXIT]]:` and `label %[[EXIT]]`: UTC generalized them
as `[[@@]]:` and `label %[[@@]]`, which mismatched with the
generalization of new lines.
This mismatch might cause unexpected variable name remappings, even if
the new lines are indeed equivalent to the old lines.
This PR aligns label var handling of old lines to new lines, i.e.,
generalizes `[[EXIT]]:` and `label %[[EXIT]]` as `[[@@]]` and `[[@@]]`.

float behavior, so over time most targets have switched to use
`softPromoteHalfType`. Swap to soft promotion by default and add
overrides for SystemZ and AMDGPU, which are the two remaining backends
that still depend on this behavior.
All basic `f16` op tests now pass on all remaining experimental arches.

implemented using getSignedMaxValue().isNonPositive().
2. SignPredicatesExhaustive test - An exhaustive test that validates the
correctness of isNegative(), isNonNegative(), isStrictlyPositive(),
isNonPositive(), and isNonZero() by iterating through all possible
KnownBits combinations for 1-bit and 4-bit widths and verifying that the
predicates return true if and only if all possible values represented by
the KnownBits satisfy the predicate.

[CIR][AArch64] Add lowering for unpredicated svdup builtins (#174433)
This PR adds CIR lowering support for unpredicated `svdup` SVE builtins.
The corresponding ACLE intrinsics are documented at:
* https://developer.arm.com/architectures/instruction-sets/intrinsics
(search for svdup).
Since LLVM provides a direct intrinsic for svdup with a 1:1 mapping, CIR
lowers these builtins by emitting a call to the corresponding LLVM
intrinsic.
DESIGN NOTES
------------
With this change, ACLE intrinsics that have a corresponding LLVM intrinsic can
generally be lowered by CIR by reusing LLVM intrinsic metadata, avoiding
duplicated intrinsic-name definitions, unless codegen-relevant SVETypeFlags are
involved. As a consequence, CIR may no longer emit NYI diagnostics for
intrinsics that (a) have a known LLVM intrinsic mapping and (b) do not use such
codegen-relevant `SVETypeFlag`s; these intrinsics are lowered directly.
IMPLEMENTATION NOTES
--------------------
* Intrinsic discovery logic mirrors the approach in
CodeGen/TargetBuiltins/ARM.cpp, but is simplified since CIR only
requires the intrinsic name.
* Test inputs are copied from the existing svdup tests:
tests/CodeGen/AArch64/sve-intrinsics/acle_sve_dup.c.
* The LLVM IR produced _with_ and _without_ `-fclangir` is identical,
modulo basic block labels, SROA, and function attributes.

The out-of-process execution in the interpreter depends on the orc

path. However, the clang runtime path is relative to clang's resource
directory which is relative to the clang binary. That does not work well
if clang is linked into a different binary which can be in a random
place in the build directory structure.
This patch performs a conservative approach to detect the common
directory structure and correctly infer the paths. That fixes the
out-of-process execution unittests. The patch also contains a small
adjustment for solaris.
Another take on trying to fix the issue uncovered by #175322.

[SystemZ] Remove the `softPromoteHalfType` override (#175410)
`softPromoteHalfType` is being phased out because it is prone to

remaining platforms to override the default, so remove it here.
This only affects SystemZ when the `soft-float` option is used.

The testcase has been dropped from this recommit as it failed on several

re-introduce the testcase in a follow-up commit so that it cane be
iterated on (and re-reverted if necessary) without affecting the options
introduced by this commit. (Since these options are best-effort
debugging tools it's ok if they live in-tree without a test for now).

0x2b750 [0xa8]: failed to process type: 10 [Operation not permitted]
```
It turns out that Header's Flags field was never initialized, so the
value could be random.
This patch fixes the issue by initialising all Header's fields.

[RISCV] Schedule RVV instructions with compatible vtype/vl first
This can reduce some vsetvli toggles.
This can be done in pre-ra scheduling as we have moved insertion of
vsetvli after the first RA.
Currently, we override `tryCandidate` and add a new heuristic based
on comparison of `vtype`/`vl`.

[PowerPC] Optimize not equal compares against zero vectors (#150422)
This patch is for special cases involving 0 vectors. During the
comparison of vector operands, current code generation checks with
`vcmpequh (vector compare equal unsigned halfword)` followed by a
negation `xxlnor (VSX Vector Logical NOR XX3-form)`.
This means that for the special case, instead of using `vcmpequh` and
then negating the result, we can directly use `vcmpgtuh (vector compare
greater than unsigned halfword)`.
As a result the negation is avoided since the only condition where this
will be false is for 0 as it is an `unsigned halfword`.

[SPIR-V] Fix Linkage capability with pushconstant (#175192)
When the SPIR-V backend handles a push constant, a new global with a
target-specific is generated. This global should have the same
visibility as the source, but turns out it was not the case: linkage was
still external, but visibility went from hidden to visible.
This causes the later passes to generate a Linkage decoration, adding
the Linkage capability, which is not compatible with Vulkan. Fixing
this.

And skip the isBeforeLegalize check when lowering i8 muls, because it

v16i8.
Also explicitly disable memory interleaving for any factor other than
two or four.

[clang-repl] Rework layering of incremental executors. (#175448)
The original Interpreter implementation had a hard dependency on ORC and
grew organically with the addition of out-of-process JIT support. This
tightly coupled the Interpreter to a specific execution engine and
leaked ORC-specific assumptions (runtime layout, symbol lookup,
exception model) into higher layers.
The WebAssembly integration demonstrated that incremental execution can
be implemented without ORC, exposing the need for a cleaner abstraction
boundary.
This change introduces an IncrementalExecutor interface and moves
ORC-based execution behind a concrete implementation. The Interpreter
now depends only on the abstract executor, improving layering and
encapsulation.
In addition, the Interpreter can be configured with user-provided
incremental executor implementations, enabling ORC-independent
execution, easier testing, and future extensions without modifying the
core Interpreter.

[LLDB] Fix MS STL `variant` with non-trivial types (#171489)
When using `std::variant` with non-trivial types, we need to go through
multiple bases to find the `_Which` member. The MSVC STL implements this
in `xsmf_control.h` which conditionally adds/deletes copy/move
constructors/operators.
We now go to `_Variant_base` (the holder of `_Which`). This inherits
from `_Variant_storage`, which is our entry point to finding the n-th
storage (going through `_Tail`).

[AMDGPU][SIInsertWaitcnt] Implement Waitcnt Expansion for Profiling (#169345)
Reference issue: https://github.com/ROCm/llvm-project/issues/67
This patch adds support for expanding s_waitcnt instructions into
sequences with decreasing counter values, enabling PC-sampling profilers
to identify which specific memory operation is causing a stall.
This is controlled via:
Clang flag: -mamdgpu-expand-waitcnt-profiling /
-mno-amdgpu-expand-waitcnt-profiling
Function attribute: "amdgpu-expand-waitcnt-profiling"
When enabled, instead of emitting a single waitcnt, the pass generates a
sequence that waits for each outstanding operation individually. For
example, if there are 5 outstanding memory operations and the target is
to wait until 2 remain:
**Original**:
s_waitcnt vmcnt(2)
**Expanded**:
s_waitcnt vmcnt(4)
s_waitcnt vmcnt(3)
s_waitcnt vmcnt(2)
The expansion starts from (Outstanding - 1) down to the target value,
since waitcnt(Outstanding) would be a no-op (the counter is already at
that value).
- Uses ScoreBrackets to determine the actual number of outstanding
operations
- Only expands when operations complete in-order
- Skips expansion for mixed event types (e.g., LDS+SMEM on same counter)
- Skips expansion for scalar memory (always out-of-order)
Releated previous work for Reference
- **PR**: llvm/llvm-project#79236 (related `-amdgpu-waitcnt-forcezero`)

[llvm-jitlink] Make -show-addrs work without -check, fix fallout. (#175491)
Ensures that the address scraping passes are added to the JIT linker pipeline
if either of the -check or -show-addrs are passed. Prior to this commit we only
considered -check, so passing -show-addrs on its own was printing an empty
(unpopulated) symbol table.
This change exposed bugs in RuntimeDyldChecker's `MemoryRegionInfo` type, aned
llvm-jitlink's symbol printing code:
- `MemoryRegionInfo` was assuming that zero-sized symbols wouldn't be defined
and was using Size == 0 as a proxy for "region info uninitialized". This was
triggering assertions for valid LinkGraphs containing zero-sized symbols.
- llvm-jitlink's symbol printing code was assuming that all defined symbols
contained content, and was not correctly handling zero-fill / absolute
symbols. This triggered assertions about requesting content addresses for
non-content symbols.
This commit fixes the issues above, and adds both a generic testcase for the
-show-addrs option, and an ELF-specific testcase with a zero-sized symbol to
check that the option works for such symbols.

[Clang] prevent an assertion failure caused by C++ constant expression checks in C23 floating conversions (#174113)
Fixes #173847
---
This patch addresses an assertion failure during compilation of C23 code
involving floating-point conversions.
As part of the C23 constexpr support introduced in PR #73099, Clang
began reusing parts of the C++ constant evaluation and narrowing logic.
In C23 mode, a failed constant evaluation caused the condition to
proceed to C++ constant-expression checks, resulting in an assertion
failure.
This change evaluates constants using `EvaluateAsRValue` in C23 mode and
restricts C++ constant-expression checks to C++ mode.

[include-cleaner] Report refs from macro-concat'd tokens as ambigious (#175532)
Previously we completely ignored these references as we couldn't detect

wanted to prevent false positives. Unfortunately these are resulting in
false negatives in certain cases and are breaking builds.
After this change, include-cleaner will treat such references as
ambigious to prevent deletion of likely-used headers (if they're already
directly included), while still giving user the opportunity to
explicitly delete them.

we use millicode for the strcpy function instead of a library call to
improve performance.

[flang] Enhance show_descriptor intrinsic to avoid extra descriptor copies (#173461)
Originally, the argument to show_descriptor() intrinsic was declared
with the passing mechanism of "asBox". This resulted in `fir.load`
instruction to be emitted to pass descriptor "asBox", which resulted in
extra llvm.memcpy in LLVM IR. The current change eliminates this, so
that show_descriptor() prints information about the original descriptor,
not about its copy.
The current change modifies the passing mechanism of the argument to
show_intrinsic() to "asInquired". The lowering of show_descriptor() now
passes the reference to a descriptor directly to the runtime routine. If
descriptor is passed as a value in SSA register, then it's spilled on
the stack and its address is passed to the runtime routine. If a
non-descriptor value is passed to show_descriptor(), then this value is
spilled to the stack, wrapped into a descriptor that is also spilled to
the stack, and the resulting descriptor pointer is passed to
show_descriptor().
show_descriptor() LIT test was modified to correspond to the new
implementation and additional test cases were added to it.

[VPlan] Remove verifier check that EVL can only be used by VPInstruction with one use (#175502)
Fixes #175028
We have a VPlanVerifier assertion that a VPInstruction that uses EVL
only has one use. This used to hold until we implemented CSE, but now we
can run into the case where e.g. a multiply from an expanded
VPWidenPointerInductionRecipe gets cse'd, causing it to have multiple
uses:
EMIT ir<%0> = WIDEN-POINTER-INDUCTION ir<%.pre3>, ir<6>, vp<%5>
EMIT ir<%1> = WIDEN-POINTER-INDUCTION ir<%.pre>, ir<6>, vp<%5>
EMIT-SCALAR vp<%5> = EXPLICIT-VECTOR-LENGTH vp<%avl>
-->
EMIT-SCALAR vp<%10> = EXPLICIT-VECTOR-LENGTH vp<%avl>
EMIT vp<%11> = mul ir<6>, vp<%10>
EMIT vp<%ptr.ind> = ptradd vp<%pointer.phi>, vp<%11>
EMIT vp<%12> = mul ir<6>, vp<%10>
EMIT vp<%ptr.ind>.1 = ptradd vp<%pointer.phi>.1, vp<%12>
-->
EMIT-SCALAR vp<%5> = EXPLICIT-VECTOR-LENGTH vp<%avl>
EMIT vp<%6> = mul ir<6>, vp<%5>
EMIT vp<%ptr.ind> = ptradd vp<%pointer.phi>, vp<%6>
EMIT vp<%ptr.ind>.1 = ptradd vp<%pointer.phi>.1, vp<%6>
This removes the check, as I'm not sure it's that useful anymore now
that we have CSE. Coincidentally, this crash only happened on RV32
because RV64 requires zexting the EVL, which sidesteps a lot of the
checks to begin with.

[SCEV] Handle all PtrtoIntExpr construction in CastSinkingRewriter (NFC) (#174435)
Move SCEVPtrToIntSinkingRewriter out of getLosslessPtrToIntExpr to be
re-used for PtrToAddr. Also streamline code in getLosslessPtrToIntExpr
by moving zero handling to the rewriter and removing special handling
for SCEVUnknown in getLosslessPtrToIntExpr. Instead, always use the
rewriter, which will automatically handle the case where the expression
is a SCEVUnknown.
This makes it slightly easier to add support for PtrToAddr as follow-up

These intrinsics can be converted to `@llvm.maxnum` and `@llvm.minnum`.
This optimization can be done if the inputs are free of: NaN, Inf,
Subnormal, and NegZero. If it is not sure to be free of these, the
instructions remain the same.

[llvm][formatters] Add LLDB formatter for llvm::PointerUnion (#175218)
We make use of the fact that the `PointerUnion` element is a
`PointerIntPair`, for which we have a synthetic provider already. We get
the `Int` portion of the pair (which is the index into the template
parameter pack of the union) to get the active type and the `Pointer`
portion of the pair to get the actual pointer value.
Before:
```
(lldb) (lldb) v -T z_float
(llvm::PointerUnion<Z *, float *>) z_float = {
(llvm::pointer_union_detail::PointerUnionMembers<llvm::PointerUnion<Z *, float *>, llvm::PointerIntPair<void *, 1, int, llvm::pointer_union_detail::PointerUnionUIntTraits<Z *, float *> >, 0, Z *, float *>) llvm::pointer_union_detail::PointerUnionMembers<llvm::PointerUnion<Z *, float *>, llvm::PointerIntPair<void *, 1, int, llvm::pointer_union_detail::PointerUnionUIntTraits<Z *, float *>, llvm::PointerIntPairInfo<void *, 1, llvm::pointer_union_detail::PointerUnionUIntTraits<Z *, float *> > >, 0, Z *, float *> = {

[AArch64] Add support for range prefetch intrinsic (#170490)
This patch adds support in Clang for the RPRFM instruction, by adding
the following intrinsics:
```
void __pldx_range(unsigned int *access_kind*, unsigned int retention_policy,
signed int length*, unsigned int count, signed int stride,
size_t reuse distance, void const *addr);
void __pld_range(unsigned int access_kind*, unsigned int retention_policy,
uint64_t metadata, void const *addr);
```
The `__ARM_PREFETCH_RANGE` macro can be used to test whether these
intrinsics are implemented. If the RPRFM instruction is not available, this
instruction is a NOP.
This implements the following ACLE proposal:

[SPIRV] Deduce result type for `G_SEXT` and `G_ZEXT` (#175401)
During legalisation we can fold / combine `sext` followed by a widening
via `zext`. Unfortunately, this yields a new result register with no
SPIRV Type, which leads to incorrect behaviour during post legalisation
when we end up deducing the (narrower) type from the operand. This patch
corrects the behaviour in that it ensures that we use the (widened) type
of the result to yield the SPIRV Type for the register.

[lldb][Formatters] Remove broken/redundant lookup into anonymous child when extracting from compressed pairs (#175564)
(brought to my attention in
https://github.com/llvm/llvm-project/pull/155153#discussion_r2682666325)
This patch removes the `anon_struct_idx` of
`GetValueOrOldCompressedPair`.
The latest `_LIBCPP_COMPRESSED_PAIR` wraps the members in an anonymous
structure. Around the time of the original patch that introduced
`GetValueOrOldCompressedPair`
(https://github.com/llvm/llvm-project/pull/155153),
`GetChildMemberWithName` wasn't capable of "seeing through" anonymous
structures when searching for children. However, around the same time as
https://github.com/llvm/llvm-project/pull/155153 landed, the
`GetChildMemberWithName` behaviour was fixed (in
https://github.com/llvm/llvm-project/pull/138487). So regardless of
whether the the compressed pair is wrapped in an anonymous structure,
simply calling `GetChildMemberWithName` is the right thing to do.
We weren't even using the result of `GetChildAtIndex`, so we were always
calling `GetChildMemberWithName` with the root ValueObject anyways.
Our `libcxx-simulators` already test both compressed pair layouts, so no
extra coverage is needed here.

[X86][NewPM] Port x86-fixup-inst-tuning (#175576)
Port x86-fixup-inst-tuning to the new pass manager. Standard porting
with refactoring of the pass to an impl, renaming the legacy pass, and
adding a NewPM wrapper around the impl. No test coverage added for now
as there are no MIR->MIR tests exercising this pass and we do not have
enough ported to run any end to end tests.

This is an NFC (No Functional Change) refactoring that improves code
maintainability by extracting reusable verification logic into a shared
utility.

[HLSL][Matrix] Load and store ConstantMatrixBoolTypes as i32 FixedVectorTypes (#175245)
Fixes #175236
This pull request improves support for HLSL constant matrix types with
boolean elements in Clang's code generation. The main changes ensure
that boolean (i1) matrices are correctly represented and stored as i32
vectors in LLVM IR. This includes updates to both the code generation
logic and related tests.
### Code generation improvements for HLSL boolean matrices
* Updated `convertTypeForLoadStore` in `CodeGenTypes.cpp` to represent
constant matrix types with boolean elements as `FixedVectorType` of
integers, ensuring atomic load/store operations and correct element type
conversion for HLSL.
* Modified `EmitToMemory` in `CGExpr.cpp` to handle both
`ExtVectorBoolType` and `ConstantMatrixBoolType`, improving the handling
of boolean matrices during memory emission.
### Test updates for boolean matrix codegen
* Adjusted test expectations in `BoolMatrix.hlsl` to reflect the new
representation, showing stores and loads of `<N x i32>` instead of `<N x
i1>` for boolean matrices, and added zero-extension where necessary.
* Added a new test for a 4x4 boolean matrix function to verify correct
code generation for initial stores to boolean matrix parameter
declaration allocas.

[flang] Fix SelectCaseOpConversion to convert block signatures (#175298)
When `fir.select_case` branches to blocks with arguments that have FIR
types (e.g., `!fir.ref`), the block signature must be converted to LLVM
types before creating the branch. Otherwise, the branch passes LLVM
types (`!llvm.ptr`) but the block expects FIR types, causing a type
mismatch error.
This adds block signature conversion similar to what
`SelectOpConversionBase` already does for `fir.select` and
`fir.select_rank`.

[flang][acc] Implement cache directive lowering (#174897)
The `acc.cache` operation is currently defined to be associated with a
loop. However, this implementation generates `acc.cache` as a standalone
data entry operation inside the loop body. The `acc.cache` operation
definition should be updated in a future change to reflect this usage.
Key implementation details:
- Add semantic checks to validate cache-specific constraints: at least
one bound must be specified for array sections, and only unit stride
is supported
- Use the shared `gatherDataOperandAddrAndBounds` infrastructure to
generate `acc.bounds` for cache operands, handling single elements
(`arr(i)`), full ranges (`arr(l:u)`), and partial ranges with missing
bounds (`arr(l:)` or `arr(:u)`)
- Set the data clause to `acc_cache` with the `readonly` modifier via
the `modifiers` attribute when the `readonly` clause is present
- Update the symbol map so subsequent lowering uses the cache result
- Insert cache operations after loop iterator setup
- Add symbol scope management for constructs inside `acc.loop`

[libc++] Fix filebuf resetting its underlying buffer upon close() (#168947)
When closing a filebuf, we would previously call setbuf(0, 0). Not only
does this get rid of any underlying buffer set by the user, but it also
sets the unbuffered mode.
This means that if the filebuf is then reopened to keep writing to a
file, it would have lost track of the original user-provided buffer (or
the default one which has a size of 4096), and instead it would use the
unbuffered mode, which is terribly slow.
This led to a bug report where users were complaining that closing and
reopening the filebuf led to a significantly worse performance than
using it without having closed and reopened. While this is a slightly
unusual usage pattern, it should definitely work.

[InstCombine] Fix i1 ssub.sat compare folding (#173742)
For every type other than i1, ssub.sat x, y = 0 implies x == y. But
ssub.sat.i1 0, -1 = 0 (because the result of 1 saturates to 0).
The changes to instcombine are not strictly necessary. Instcombine
canonicalizes the ssub.sat.i1 before we arrive at these pattern-matches.
The real fix is in ValueTracking.
Nonetheless we agreed in review it makes sense to add these checks to
instcombine, even though they're currently unreachable:

[NVPTX] Validate user-specified PTX version against SM version (#174834)
When users explicitly specify a PTX version via `-mattr=+ptxNN` that's
insufficient for their target SM, we now emit a fatal error. Previously,
we silently upgraded the PTX version to the minimum required for the
target SM.
When no SM or PTX version is specified, we now use PTX 3.2 (the minimum
for the default SM 3.0) instead of PTX 6.0.

[libc++] Remove some low value benchmarks (#175178)
This patch removes some of the benchmarks in our suite that are
relatively low value. Specifically:
- `lexicographical_compare` isn't benchmarked with every number of
elements between 1 and 8 anymore
- `bitset` isn't benchmarked with as many sizes anymore. Instead, only
some representative sizes are benchmarked.
- `to_chars` isn't benchmarked for every possible base anymore, but only
2, 8, 10, 16 and 23 (so we have an uncommon base as well)

[AMDGPU]: Rewrite mbcnt_lo/mbcnt_hi to work item ID where applicable (#160496)
This PR aims to optimize `llvm.amdgcn.mbcnt.lo` and
`llvm.amdgcn.mbcnt.hi` intrinsic patterns into simpler `workitem.id.x`
operations when work group sizes are known at compile time for
**improving performance of lane ID calculations**.
**visitMbcntLo:**
- Simple replacement: When `workgroup_size == wave_size` → Replace with
`workitem.id.x`
- Bitmask optimization: When work group evenly splits into waves →
Replace with `workitem.id.x & (wave_size - 1)`
**visitMbcntHi:**
- Copy optimization: On wave32, `mbcnt.hi(mask, val)` → `val` (upper 32
bits are always 0)
- Full pattern optimization: `mbcnt.hi(~0, mbcnt.lo(~0, 0))` → Replace
with `workitem.id.x`
**Example 1: Simple Replacement**
```llvm
; Before:
%a = call i32 @llvm.amdgcn.mbcnt.lo(i32 -1, i32 0); With workgroup_size = 32
; After:
%a = call i32 @llvm.amdgcn.workitem.id.x()
```
**Example 2: Bitmask Optimization**
```llvm
; Before:
%a = call i32 @llvm.amdgcn.mbcnt.lo(i32 -1, i32 0); With workgroup_size = 64 (2 waves)
; After:
%tid = call i32 @llvm.amdgcn.workitem.id.x()
%a = and i32 %tid, 31
```
**Example 3: Copy Optimization**

Remove CXXRecordDecl printer FIXME (#175397)
It suggested it would be better to print attributes before the decl
kind, to be consistent with value declarations.
But attributes are not accepted by the language before the decl kind:
[[deprecated]] class A;
__attribute__((deprecated)) class A;
__declspec(deprecated) class A;
are all invalid or ignored. The only way to put an attribute before the
decl kind is with something like:
[[deprecated]] struct A {} a;
But that declares a variable, not a record tyoe, and will be correctly
handled by the variable decl printer.

[flang][OpenMP] Fix crash when arrays used in LINEAR clause (#175383)
Closes #171007
Found this crash while testing OpenMP code - turns out putting an array
in a LINEAR clause on SIMD directives causes the compiler to blow up
with "unknown LLVM dialect type" and hit an UNREACHABLE.
The issue is that LINEAR clauses only accept scalar variables (rank 0),
but we weren't checking for that early enough. The invalid array type
would slip through semantic analysis and then crash during MLIR to LLVM
IR translation when it tried to convert the type.
**What changed:**
- Added a rank check in the LINEAR clause validation to catch arrays up
front
- Made an exception for `declare simd` with the REF modifier since
that's actually allowed per spec
- Added tests covering different array types (1D, multi-dim,
assumed-shape)
- Updated existing tests that now catch the new error
Tested with the original reproducer and it now fails cleanly with a
proper error message instead of crashing.

-Add CIR support for pmovqd512_mask.

truncation-and-selection logic
[X86.cpp.](https://github.com/llvm/llvm-project/blob/main/clang/lib/CodeGen/TargetBuiltins/X86.cpp#L1638),
so I added support for pmovwb512_mask using the same logic.
-Added a new LIT test case in
clang/test/CIR/CodeGen/pmovqd-mask-builtins.c to verify correct CIR
generation for both builtins.
-Added a type cast fix in CirGenCleanup.cpp where std::max encountered a
type mismatch between size_t and unsigned long on Win64. This caused
compile error on Windows for me while building it. Edit: This fix has
been moved to here https://github.com/llvm/llvm-project/pull/174519
This is my first request to this repo. If you noticed anything wrong
please comment and I'm looking forward for corrections.

[Clang] Improve CodeGenerator API a bit (#175239)
Essentially, figuring out how to use `CodeGenerator` was very confusing
to me and I figured the API could be improved a bit, so:
- the `CodeGenerator` ctor is now protected since an instance of
`CodeGenerator` that is not a `CodeGeneratorImpl` is a bit useless (and
deriving from it and implementing it yourself honestly just defeats the
point of using this to begin with);
- `ReleaseModule()` releases ownership of the module, so it should
return a `unique_ptr`;
- `CreateLLVMCodeGen()` also returns a `unique_ptr` now;
- added a `CreateLLVMCodeGen()` overload that takes a
`CompilerInstance&` and uses some of its state instead of requiring the
user to pass everything in manually; this is consistent w/ other parts
of our API, and most uses of this function in the codebase can be
refactored to use that overload instead (and a code search I did also
showed that a lot of people that use this API also just use the state
from a `CompilerInstance`).
I should have liked to replace `CreateLLVMCodeGen` w/
`CodeGenerator::Create`, but there are a lot of uses of
`CreateLLVMCodeGen()` in the wild, so the only thing we could do is keep
`CreateLLVMCodeGen()` and deprecate it, and at that point I don’t think
it’s really worth it; I added a comment to the `CodeGenerator()`
constructor declaration that points to it though.
Fixes #172169.

LSan, by design, can have false negatives, making it unreliable to check

[lldb][TypeSystem] Call Type::isIntegralType from TypeSystemClang::IsIntegerType (#175669)
Instead of re-implementing `Type::isIntegralType`, call it explicitly.
This means we get support for `BitIntType` out-of-the-box.
We don't use `IsIntegerType` here because we want to abide by the
language-specific notions of an integer type (which differ between C++
and C).
The slight behaviour change here is that `IsIntegerType` will now treat
complete enumerations as integers in C. This is correct according to the
C standard.

[flang] Fix spurious NaN result from infinite Kahan summation (#175373)
There are six instances of Kahan's extended precision summation
algorithm in flang/flang-rt, and they share a bug: the calculation of
the correction value produces a Nan due to the subtraction Inf-Inf after
the accumulation saturates to Inf. This leads to the surprising Nan
result from SUM([Inf, 0.]).
This bug doesn't affect run-time calculation of SUM when optimization is
enabled -- lowering emits an open-coded SUM that lacks Kahan summation
-- but it does affect compilation-time folding and -O0 runtime results.
Fix the one instance of Kahan summation in the runtime, and consolidate
the other five instances in Evaluate into one new member function, also
corrected.

[llvm-jitlink] Remove flaky testcase. (#175680)
On some systems, backtraces contain addresses with their high bits set*.
These high bits prevent symbolication using the JIT symbol table. Since
this test is for a best-effort debugging / diagnosis tool it seems best
to remove the test until/unless we can get it passing on all systems, or
find some way to identify systems that will fail.
See discussion in https://github.com/llvm/llvm-project/pull/175537.
* Note that the test does not use PAC or pointer tagging -- the high
bits are coming from somewhere else. Possibly libunwind, but that is
just speculation.

[clang][Tooling] Fix assertion failure when processing CUDA files (#173762)
Running clang-tidy on CUDA files without specifying `--cuda-host-only`
or `--cuda-device-only` would trigger an assertion failure in
`Actions.size() > 1`, a related discussion:
https://github.com/llvm/llvm-project/pull/173699#discussion_r2649279975.
This occurred because the Clang Driver generates a single top-level
`OffloadAction` in `-fsyntax-only`, `-E`, `-M`. This commit removes the
overly strict assertions.
Closes #173777

[profcheck] Fix encoding of 0 loopEstimatedTrip count (#174896)
We currently encode an estimated trip count of 0 as the latch having branch probabilities 0-0. That's an invalid pair of weights. The probability of a branch is computed as a fraction of its corresponding weight and the sum of the weights. In fact, `BranchProbabilityInfo::calcMetadataWeights` will convert this to a 1-1, meaning 50% - 50%, which isn't quite what we want. To indicate the loop is never taken, we just need to initialize the exit probability to non-zero (hence, 1)

[cmake] Make CMAKE_BUILD_TYPE=Release the default (#174520)
Currently, we report a fatal error if the user leaves CMAKE_BUILD_TYPE
blank. This was implemented in https://reviews.llvm.org/D124153 /
350bdf9227ceb , based on this RFC:
https://discourse.llvm.org/t/rfc-select-a-better-linker-by-default-or-warn-about-using-bfd/61899/1
Tom Stellard mentioned that he'd like to revisit this on Discord, and
Aiden, myself, and apparently most people on the original RFC agree, so
I'm proposing we do it. However, on the review, several folks objected
and insisted that Debug was a better default. I want to reopen the
question.
I think we've made the wrong tradeoff. I wish Debug builds worked out of
the box on most systems, but they don't, and LLVM has only gotten bigger
over the last four years, making the build scalability problems of Debug
builds worse. I think we should optimize our build configuration for new
developers, not experienced longtime contributors who are invested
enough to tweak the build to their liking.
With this PR, we emit a warning, and set the build type to Release,
which has a higher likelihood of success for first-time users. Making
the build work out of the box is very important for making LLVM
development more accessible to new contributors, so it seems worth
smoothing over this rough edge.
A separate possible improvement would be to set
LLVM_ENABLE_ASSERTIONS=ON, but that is out of scope for this PR.

in incorrect pseudo instruction opcodes lookup -- and to a larger
extent, incorrect scheduling class lookups -- in llvm-mca. This patch
fixes such issue.

[UniformityAnalysis] Jump over reducible cycles when locating join blocks (#174938)
When locating the join blocks of a divergent block, the algorithm relies
on pseudo-edges from the header of a reducible cycle to the cycle exits.
This was missed in the actual traversal, producing unnecessary joins
inside the reducible cycle. This caused an assert in the included test,
which expected that if a join existed in a reducible cycle for a
divergent branch outside the cycle, then it must be header.
This fixes the reverted commit from #174117

Calling `peek()` after constructing a stream is something one can use to
make the stream ignore empty inputs:
```
#include <sstream>
int main() {
std::istringstream s;
s.peek();
while (s && !s.eof()) {
char c;
s >> c;
printf("not eof; read \'%c\' (%d)\n", c, c);
}
}
```
as discussed in
https://github.com/llvm/llvm-project/pull/173754#discussion_r2669631585
this patch removes the `[[nodiscard]]` annotation.

[LoongArch] Enable tail calls for sret and byval functions (#168506)
Allow tail calls for functions returning via sret when the caller's sret
pointer can be reused. Also support tail calls for byval arguments.
The previous restriction requiring exact match of caller and callee
arguments is relaxed: tail calls are allowed as long as the callee does
not use more stack space than the caller.
Fixes #168152

part of 'f'. Make it a 4-bit 'f' and make the derived classes
concatenate the 0/1 when they need to widen from 3 bits to 4.

[clang-doc] Fix misnamed, mismatched, or incorrect tags (#175112)
This is mostly a chore patch that fixes misnamed, mismatched,
or non-existant tags. That includes renaming the function tags in the
class template to `Has*Methods` instead of `Has*Functions`. The "method"
style was already preferred in the template HTML.
Some extraneous tags were removed from the enum template. All templates
should use
`Description` for rendering comments, but it was still using an old tag
name. Also, the JSON generator currently doesn't serialize individual
enum value comments, so that tag was removed. Same for public members.
`Description` is removed for friends due to the way Mustache handles
missing
tags. If `Description` isn't present, it will use the parent's
description which is undesirable.

[LLD][MachO][NFC] Rename Reloc to Relocation (#175586)
Due to heavy use of using namespace llvm, Reloc is often ambiguous with
llvm::Reloc, the relocation model. Previously, this was sometimes
disambiguated with macho::Reloc. This ambiguity is even more problematic
when using pre-compiled headers, where it's no longer "obvious" whether
it should be Reloc or macho::Reloc.
Therefore, rename Reloc to Relocation. This is also consistent with
lld/ELF, where the type is also named Relocation.

[mlir] Consolidate patterns into `RegionBranchOpInterface` patterns (#174094)
Instead of op-specific cleanup patterns for region branch ops to remove
unused results / block arguments, etc., add a set of patterns that can
handle all `RegionBranchOpInterface` ops. These patterns are enabled
only for selected SCF dialect ops at the moment:
* `scf.execute_region`
* `scf.for`
* `scf.if`
* `scf.index_switch`
* `scf.while`
It is currently not possible to register canoncalization patterns for op
interfaces and some ops have incorrect interface implementations. In
follow-up PRs, the set of ops will be gradually extended within the SCF
dialect (`scf.forall`) and across other dialects
(`gpu.warp_execute_on_lane0`, (maybe) various affine dialect ops, ...),
and maybe eventually to apply to all `RegionBranchOpInterface` ops.
This commit removes many similar canonicalization patterns from the SCF
dialect. The newly added canonicalization patterns allow users to get
the same canonicalizations for free for their own ops. And even a few
additional new canonicalizations
([example](https://github.com/llvm/llvm-project/pull/174094/files#diff-54318cd685386d5519c42be49818e388b09d934edcbe4280548baa3601802977R2241),
[example](https://github.com/llvm/llvm-project/pull/174094/files#diff-54318cd685386d5519c42be49818e388b09d934edcbe4280548baa3601802977R1101),
...).
Implementation outline: This commit adds 3 canonicalization patterns.
* `MakeRegionBranchOpSuccessorInputsDead`: Remove uses of successor
inputs, by swapping them for successor operand values.
* `RemoveDuplicateSuccessorInputUses`: Remove uses of successor inputs
that are duplicates. (Similar to `WhileRemoveDuplicatedResults` in the
SCF dialect.)
* `RemoveDeadRegionBranchOpSuccessorInputs`: Remove dead successor
inputs if all of their "tied" successor inputs are also dead. (Similar
to `WhileUnusedResult` in the SCF dialect.)

The bytecode interpreter was crashing when seeing arrays with sizes that

Program::createDescriptor was using std::numeric_limits<unsigned>::max()
instead of the correct limit Descriptor::MaxArrayElemBytes.
This caused the check to pass for sizes that would later fail the
assertion in the Descriptor constructor.

In this case, we're experiencing a crash because we can have a PtrAdd
that uses EVL. This fixes it by adding PtrAdd to the list of allowed

Fixes https://github.com/llvm/llvm-project/issues/172013
Fixes https://github.com/llvm/llvm-project/issues/175391
This PR adds support for merging the `lifetimebound` attribute on the implicit `this` parameter when merging method declarations. Previously, if a method was declared with `lifetimebound` on its function type (which represents the implicit `this` parameter), this attribute would not be propagated to the method definition, causing lifetime safety warnings to be missed.
The implementation adds helper functions to extract the `lifetimebound` attribute from a function type and to merge this attribute from an old method declaration to a new one when appropriate.

The tests function has an unreachable block bb.2 leading to an
unreachable infinite loop bb.3. As BlockFolding removes the unreachable
bb.2, bb.3 is left only referencing itself. This block is then not
marked as unreachable and so left out of EHScopeMembership, leading to
an assert that FallThroughEHScope != EHScopeMembership.end(). This patch
makes sure that blocks not otherwise collected are added to
EHScopeMembership in the same way as unreachable blocks.

[llvm][release] Reveal download links based on uploaded assets (#167688)
For the 21.x release, download links were supposed to be revealed once
all the release builds had completed successfully. In reality, MacOS
never had a successful build so I had to hand edit the release messages.
This PR fixes this by focusing instead on what is in the release assets
after the release build step has finished (in whatever state that might
be).
1. Links are now built from a format string, with the linked files being
format arguments for that string. This is a balance between ease of
editing the format, and having the file names for use later (I tried
regex-ing file names out of the final links, which can work but is error
prone and will be hard to debug in production).
Here's an example line:
```
<!-- LINUX_X86 * [Linux x86_64](https://github.com/llvm/llvm-project/releases/download/llvmorg-vX.Y.Z-1/LLVM-vX.Y.Z-1-Linux-X64.tar.xz) ([signature](https://github.com/llvm/llvm-project/releases/download/llvmorg-vX.Y.Z-1/LLVM-vX.Y.Z-1-Linux-X64.tar.xz.jsonl)) -->
```
2. `uncomment_download_links` now looks at the release assets to decide
whether to reveal a given link line. If all the files that line links to
are present, it will be revealed. This means we can run this at the end
of release-tasks.yml, where it will be atomic.
This process is done for all assets we would like to link to, not just
the ones currently built in GitHub. So if some become automatically
built, they will "just work". If we want to hand edit the links in,
that's still an option because the full links are in the release
message, but hidden from view.
As we are looking for `<!-- SOME_TAG`, the script can be run multiple
times on the same release and it will not try to edit anything already
revealed.
As it's possible no link lines have all their files, the text
immediately after the links has been updated to make sense when there
are no links.
Initially I was going to accumulate the statuses from the release build
matrix job, but this does not seem to be possible
(https://github.com/orgs/community/discussions/17245). Workarounds for
this often include uploading artifacts from each job, which for us, is
the same as checking the release's assets.

We generally try to benchmark the empty container case in the
associcative containers, since there are some case where we previously
ran calculations for significant amounts of time, even though they were
really not needed. However, there are some benchmarks where trying to
run with an empty container doesn't make sense (e.g. when benchmarking
collisions). We've worked around this a bit in the benchmarks by not
actually benchmarking the empty case. This patch removes these
meaningless benchmarks instead to speed up running the benchmarks.

[mlir] Compose expand of collapse to cast (#172864)
In some cases `y = expand(collapse(x))` cannot be folded into x, since x
and y have different types.
In that case, we check if the two types are cast compatible.
If they are, it means the two types have compatible shape and layout and
y can be folded into cast(x).
This causes a change in memref::CastOp::areCastCompatible, where now a
dim of size 1 may have different strides.

[SeparateConstOffsetFromGEP] Perform offset calculations on APInt (#175732)
In general, GEP offset calculations are allowed to overflow (if no
poison flags are set). Using int64_t for this purpose can result in C
level signed integer overflow, which is UB. It also means that we
incorrectly model whether some offsets are zero, and thus generate
redundant zero-index GEPs.
Change the code to track offsets in APInts of the pointer index size,
like we do in other places (like accumulateConstantOffset etc).

[AMDGPU][Scheduler] Scoring system for rematerializations (#175050)
This is a significant refactoring of the scheduler's rematerialization
stage meant to improve rematerialization capabilities and lay strong
foundations for future improvements.
As before, the stage identifies scheduling regions in which RP must be
reduced (so-called "target regions"), then rematerializes registers to
try and achieve the desired reduction. All regions affected by
rematerializations are re-scheduled, and, if the MIR is deemed worse
than before, rematerializations are rolled back to leave the MIR in its
pre-stage state.
The core contribution is a scoring system to estimate the benefit of
each rematerialization candidate. This score favors rematerializing
candidates which, in order, would
1. (if the function is spilling) reduce RP in highest-frequency target
regions,
2. be rematerialized to lowest-frequency target regions, and
3. reduce RP in the highest number of target regions.
All rematerialization opportunities are initially scored and
rematerialized in decreasing score order until RP objectives are met or
pre-computed scores diverge from reality; in the latter case remaining
candidates are re-scored and the process repeats. New tests in
`machine-scheduler-rematerialization-scoring.mir` showcase how the
scoring system dictates which rematerialization are the most beneficial
and therefore performed first
A minor contribution included in this PR following previous feedback is
that rollback now happens in-place i.e., without having to re-create the
rematerialized MI. This leaves original slot indices and registers
untouched. We achieve this by temporarily switching the opcode of
rollback-able instructions to a debug opcode during re-scheduling so
that they are ignored.

[lldb-dap] Add testcases for stdio redirection on different console types. (#175048)
There are some bugs when launching in terminal with args and stdio
redirection.
- lldb-dap `--stdio` args is passed to the debuggee (should we change
this to use `--` to separate debuggee args from lldb-dap args, similar
to how we handle the `--client` args? ).
#### It also changes the behaviour of stdio redirection.
If a redirection is not specified, it uses to lldb default value. e.g.
```jsonc
"stdio": ["./stdin"]`
// now becomes
"stdio", ["./stdio", "./default_stdout", "./default_stderr"]
// instead of
"stdio", ["./stdin", "./stdin", "./stdin"]
// took quite some time to figure out where my output is going to.
```
Fixes [#174445](https://github.com/llvm/llvm-project/issues/174445)
Other bug I noticed but should be in a different PR.
- debuggee args that contains newline are not properly escaped when sent
to the terminal.

[AMDGPU][Scheduler] Fix compile failure due to const/sort interaction (#175755)
On some configurations sorting `ScoredRemat` objects which contains
const members causes a compile failure due to impossibility of
swapping/moving objects. The problem was introduced in #175050.
This removes const from those fields to address the issue. The design
will soon change anyway to not rely on sorting objects of this type, and
consts were only here for semantic clarity.

command line flag, hence the warning.

[LifetimeSafety] Add support for tracking non-trivially destructed temporary objects (#172007)
Add support for tracking loans to temporary materializations that
require non-trivial destructors. We only support non-trivially
destructed temporaries as they have a nice end-of-life marker via the
`CFGTemporaryDtor`.
This small PR introduces the following changes:
1. AccessPaths can now also represent `MaterializeTemporaryExpr *` via
`llvm::PointerUnion`
3. `FactsGenerator::VisitMaterializeTemporaryExpr` now checks to see if
the temporary materialization is such that it requires a non-trivial
destructor (by checking for a child `CXXBindTemporaryExpr` node when all
implicit casts are stripped away), and if so: creates a Loan whose
AccessPath is a pointer to that `MaterializeTemporaryExpr`, and issues
it to the origin represented by the `MaterializeTemporaryExpr` node we
were called on. When we cannot find a child `CXXBindTemporaryExpr`, we
fall-back to an `OriginFlow` as before.
4. `FactsGenerator::handleTemporaryDtor` is called from
`FactsGenerator::run` when it encounters a `CFGTemporaryDtor`. It then
issues an `ExpireFact` for loan to the corresponding destructed
temporary by matching on `CXXBindTemporaryExpr *`
5. Unit tests are extended via the matcher `HasLoanToATemporary` which
can check if an origin has a loan to at least 1 temporary. This is done
as we are not nicely and reproducibly able to uniquely identify a loan
with `AccessPath` `MaterializeTemporaryExpr *`, so we settle for
checking the presence of at least a loan to a temporary.
6. A lit test is added for the case where an already destructed
temporary is used.

[libc++][test] Move the SFINAE test for return types of `quoted` to `libcxx/test/libcxx/` (#157026)
[quoted.manip] only specifies that `operator<<`/`operator>>` is
well-formed for operands with suitable types, and leaves it undefined
whether they are SFINAE-friendly.
Although it's worthwhile making them SFINAE-friendly, perhaps the
SFINAE-friendliness should be considered as a libc++-specific choice at
this moment.
See LWG4364 for whether this should be considered portable.

[mlir][SCF] Fix region branch op interfaces for `scf.forall` and its terminator (#174221)
`scf.forall` does not completely implement the
`RegionBranchOpInterface`: `scf.forall.in_parallel` does not implement
the `RegionBranchTerminatorOpInterface`.
Incomplete interface implementation is a problem for transformations
that try to understand the control flow by querying the
`RegionBranchOpInterface`.
Detailed explanation of what is wrong with the current implementation.
- There is exactly one region branch point: "parent". `in_parallel` is
not a region branch point because it does not implement the
`RegionBranchTerminatorOpInterface`. (Clarified in #174978.)
- `ForallOp::getSuccessorRegions(parent)` returns one region successors:
the region of the `scf.forall` op.
- Since there is no region branch point in the region, there is no way
to leave the region. This means: once you enter the region, you are
stuck in it indefinitely. (It is unspecified what happens once you are
in the region, but we can be sure that you cannot leave it.)
This commit adds the `RegionBranchTerminatorOpInterface` (via
`ReturnLike`) to `scf.forall.in_parallel` to indicate the after leaving
the region, the control flow returns to the parent. (Note: Only block
terminators in directly nested regions can be region branch terminators,
so `in_parallel` is the only possible op. I.e., `parallel_insert_slice`
cannot be a region branch terminator.)
This commit also removes all successor operands / inputs from the
implementation. The number of successor operands and successor inputs
must match, but `scf.forall.in_parallel` has no operands. Therefore, the
region must also have 0 successor inputs. Therefore, the `scf.forall` op
must also have 0 successor operands.
This commit also adds a missing control flow edge from "parent" to
"parent": in case of 0 threads, the region is not entered.
Depends on #174978.

Fix a PIC-only crash in Hexagon HVX lowering where we ended up treating

PC-relative addresses), which triggers a type mismatch during lowering.
Build the constant-pool reference with the target pointer type instead,
then load the HVX vector from that address.

[MLIR][Python] Improve Iterator performance. Don't `throw` in `dunderNext` methods. (#175377)
In
https://github.com/llvm/llvm-project/pull/174139#issuecomment-3733259370
I wrote a scuffed benchmark that mostly iterates MLIR Container Types in
Python. My changes from that PR made the performance worse, so I closed
it.
However, when experimetning with that I also saw a large(?) performance
gain by changing the `dunderNext` methods of the various Iterators to
use `PyErr_SetNone(PyExc_StopIteration);` instead of `throw
nb::stop_iteration();`.
<details><summary>Benchmark attempt script</summary>
```python
import timeit
from mlir.ir import Context, Location, Module, InsertionPoint, Block, Region, OpView
from mlir.dialects import func, builtin, scf, arith
def generate_module():
m = Module.create()
with InsertionPoint(m.body):
f = func.FuncOp("main", builtin.FunctionType.get([], []))
with InsertionPoint(f.body.blocks.append()):
generate_ops(10, 2)
func.ReturnOp([])
return m
def generate_ops(count: int, depth: int):
if depth == 0:
return
lower = arith.ConstantOp(builtin.IntegerType.get_signless(64), 0)
upper = arith.ConstantOp(builtin.IntegerType.get_signless(64), 100)

for i in range(count):

with Context(), Location.unknown():

# From timeit.main:
t = timeit.Timer(lambda: walk_module(m))
number, _ = t.autorange()
repeats = 5
raw_timings = t.repeat(repeats, number)
timings = [dt / number for dt in raw_timings]
best = min(timings)
print(f"{number} loops, best of {repeats}: {best * 1000:.3g} msecs per loop")
```
</details>
The performance of the benchmark went from
```
50 loops, best of 5: 5.97 msecs per loop
```
to
```
50 loops, best of 5: 5.12 msecs per loop
```
in my setup, which is a ~14% improvement. (Though you should validate
that yourself, probably. My test setup is very scuffed)
The functions were previously set to return a C++ type like `PyRegion`.
Because of the removal of the `throw` they now had to [return a `NULL`
value to
Python](https://github.com/python/cpython/blob/aa8578dc54df2af9daa3353566359e602e5905cf/Objects/call.c#L49-L61),
so I changed the return type to
`nanobind::typed<nanobind::object,PyRegion>` so I could return an
`nb::object()` in case an error was set and otherwise `nb::cast` the
`PyRegion` value to `nb::object` instead of returning it directly.
I'm not a huge fan, that this changes the external "Usage" of the
functions, because now they won't bubble up exceptions, when they are
called from C++ The return type and Python Error State have to be
checked instead.
I couldn't find any location that called them in llvm itself, though.
Maybe these functions should not be public, because they are only
supposed to be called from Python anyway?

Note some of the tests currently fail with alive, but not
due to this patch. Namely, when performing the fadd x, 0 -> x
simplification in functions with non-IEEE denormal handling.
The existing instsimplify ignores the denormals-are-zero hazard by
checking cannotBeNegativeZero instead of isKnownNeverLogicalZero.
Also note the self handling doesn't really do anything yet, other
than propagate consistent known-fpclass information until there is
multiple use support.
This also leaves behind the original ValueTracking support, without
switching to the new KnownFPClass:fadd utility. This will be easier
to clean up after the subsequent fsub support patch.

AMDGPU: Directly use v2bf16 as register type for bf16 vectors. (#175761)
Previously we were casting v2bf16 to i32, unlike the f16 case. Simplify
this by using the natural vector type. This is probably a leftover from
before v2bf16 was treated as legal. This is preparation for fixing a
miscompile in globalisel.

[ObjCDirectPreconditionThunk] Setup helper functions (#170617)
## TL;DR
This is a stack of PRs implementing features to expose direct methods
ABI.
You can see the RFC, design, and discussion
[here](https://discourse.llvm.org/t/rfc-optimizing-code-size-of-objc-direct-by-exposing-function-symbols-and-moving-nil-checks-to-thunks/88866).
https://github.com/llvm/llvm-project/pull/170616 Flag
`-fobjc-direct-precondition-thunk` set up
https://github.com/llvm/llvm-project/pull/170617 **Code refactoring to
ease later reviews**
https://github.com/llvm/llvm-project/pull/170618 Thunk generation
https://github.com/llvm/llvm-project/pull/170619 Optimizations, some
class objects can be known to be realized
## Implementation details
1. `GenerateDirectMethodsPreconditionCheck`: Move some functionalities
to a separate functions. Those functions will be reused if we move
precondition checks into a thunk
2. `GenerateClassRealization` separates the class realization `[self
self]` logic into a new function. It comes handy later when we need to
sometimes inline class realization (for va arg functions)
3. Create `DirectMethodInfo`, a two pointer struct that manage true
implementation and its thunk. When `ObjCDirectPreconditionThunk` is not
used, only true implementation is valid pointing to the LLVM IR
Function.
## Tests
None, existing ones shouldn't break

[mlir][arith] Fix SelectOp unsafe int range inference with uninitialized range case (#173716)
This PR fixes a bug in `arith::SelectOp::inferResultRangesFromOptional`
where uninitialized SelectOp branch int ranges were incorrectly joined
with initialized int ranges during dataflow analysis, leading to
incorrect folding in `-int-range-optimizations`.
**The Issue:**
When a `arith.select` branch has an uninitialized range (e.g., from an
op like `nvvm.read.ptx.sreg.cluster.ctaid.x`, `scf.switch`, `llvm.call`,
... that lacks range inference), the analysis computed
`IntegerValueRange::join(Uninitialized, Constant) = Constant`. This
caused the `arith.select` to be replaced with the constant, ignoring the
dynamic branch.
**Example:**
```mlir
// The bug before fix: -int-range-optimizations replaces %1 with %c32
// led to incorrect results and unsafe behaviours
%0 = nvvm.read.ptx.sreg.cluster.ctaid.x : i32 // Uninitialized int range
%c32 = arith.constant 32 : i32
%1 = arith.select %cond, %0, %c32 : i32
```
**The Fix:**
Explicitly ensure `inferResultRangesFromOptional` all select cases have
initialized ranges before combining them. If any case is uninitialized,
the result is now treated as max range. Also added default max range for
`nvvmInferResultRanges` and `test.without_bounds` op to simulate and
test uninitialized ranges.

Log Message:
-----------
[DA] Add tests for nsw doesn't hold on entire iteration space (NFC) (#162281)
The monotonicity definition states its domain as follows:
```
/// The property of monotonicity of a SCEV. To define the monotonicity, assume
/// a SCEV defined within N-nested loops. Let i_k denote the iteration number
/// of the k-th loop. Then we can regard the SCEV as an N-ary function:
///
/// F(i_1, i_2, ..., i_N)
///
/// The domain of i_k is the closed range [0, BTC_k], where BTC_k is the
/// backedge-taken count of the k-th loop
```
Current monotonicity check implementation doesn't match this definition
because:
- Just checking nowrap property of addrecs recursively is not sufficient
to ensure monotonicity over the entire domain. The nowrap property may
hold for certain paths but not for all possible iteration combinations
of nested loops.
- It doesn't consider cases where exact backedge-taken counts are
unknown.
Therefore we need to fix either the definition or the implementation.
This patch adds the test cases that demonstrate this mismatch.

We left an error message for users of %T through the LLVM 22 branch
point to hopefully make it easier for anyone migrating versions rather
than having the checks silently fail with a %T ending up in the executed
command. Now that 22 has branched, we can remove this check as we all
downstream users should have seen the error by this point.

[flang][Lower] Lower OmpDependClause to Depend or Doacross (#175772)
The clause::Depend class was a variant that either held a TaskDep class
or a Doacross clause. This mirrors the OmpDependClause in the AST, which
due to changes in the OpenMP spec can contain two different forms.
This is not actually necessary, and we can save some complexity by
having clause::Depend only represent task dependence, and lowering
OmpDependClause to either clause:Depend or clause::Doacross.

[SROA] Use shufflevector instead of select for vector blend (#175756)
A patch from May 2013, commit 1e211913b56f390, changed SROA into using a
select instruction to perform vector blend. Idea was that using a select
was the canonical form, and that we optimize select better than
shufflevector.
This patch is changing SROA back into using shufflevector instead of
select when doing the blend (inserting a smaller vector into a larger
vector).
Motivation:
Nowadays InstCombine is canonicalizing this kind of vector blends, using
vector select instructions, into a shufflevector instruction. So it is
assumed that shufflevector is the canonical form now. It is also assumed
that we are better at optimizing shufflevector today, compared to back
in 2013.
Commit f26710d97d9c272be8a55 includes links to a discussion from 2016
(https://discourse.llvm.org/t/ir-canonicalization-vector-select-or-shufflevector/42257/6)
about picking shufflevector as the canonical form.

[AMDGPU] Fix builtin crash with template parameter size argument (#175767)
## Summary
`__builtin_amdgcn_global_load_lds` and related builtins crash when the
size argument is a template parameter. The semantic checker calls
`VerifyIntegerConstantExpression` without first checking if the
expression is value-dependent, causing an assertion failure.
**Affected builtins:**
- `__builtin_amdgcn_global_load_lds`
- `__builtin_amdgcn_raw_ptr_buffer_load_lds`
- `__builtin_amdgcn_struct_ptr_buffer_load_lds`
- `__builtin_amdgcn_load_to_lds`
**Reproducer:**
```cpp
template<int N>
__device__ void load(void* src, __shared__ void* dst) {
__builtin_amdgcn_global_load_lds(src, dst, N, 0, 0); // Crashes
}
template __device__ void load<16>(void*, __shared__ void*);
```
**Error before fix:**
```
Assertion `!isValueDependent() && "Expression evaluator can't be called on a dependent expression."' failed
```
**Fix:** Add `isValueDependent()` check before evaluating the constant
expression. Value-dependent expressions are accepted during template
definition and properly checked during template instantiation.
## Test plan
- [x] New lit test
`clang/test/SemaHIP/amdgpu-global-load-lds-template.hip`
- Tests valid template parameter sizes compile without errors
- Tests invalid sizes are caught at template instantiation
- [x] All existing SemaHIP tests pass (17/17)
- [x] Related builtin tests pass

[AMDGPU][Scheduler] Fix use-after-poison by printing before deleting (#175807)

```
This is because it was printing an instruction that had already been
deleted. This patch fixes this by reversing the order.
