[llvm-ir2vec] Breaking up llvm-ir2vec lib implementation to clean up MIR deps from ir2vec python bindings (#194414)
The Python bindings only expose IR2Vec functionality. MIR2Vec has no
Python API. However, the single `LLVMEmbUtils` library bundled both
IR2VecTool and MIR2VecTool, causing CodeGen and Target components to be
linked into the nanobind module unnecessarily.
This patch splits the library along that boundary. LLVMIREmbUtils covers
IR2Vec and is linked by both the CLI tool and the Python bindings.
LLVMMIREmbUtils covers MIR2Vec and is linked only by the CLI tool.
Result: Python wheel size reduces from ~14 MB to ~4 MB.
[llvm-ir2vec] Setting up ir2vec python bindings testing for ml-opt bots (#194593)
- ~We are enabling IR2Vec Python binding tests in the LLVM monolithic
Linux CI by adding -D LLVM_IR2VEC_ENABLE_PYTHON_BINDINGS=ON to
monolithic-linux.sh.~
- We're adding testing for ir2vec python bindings with the ml-opt
buildbots. To that end, we need to add pip install requirements, and
other relevant flags to make way for a seamless warning-free llvm build.
The following changes are being done here
- Adding a requirements.txt file, putting out an explicit nanobind
requirement.
- Adding the option for downstream users to test bindings as part of the
`check llvm` umbrella, by passing the appropriate bindings flag
- Suppressing warnings from the nanobind headers, in order to ensure a
seamless llvm cI build
[clang-tidy] Fix false positives about reinitialization detection in `bugprone-use-after-move` (#197438)
When calling base class's `operator=` through derived object, a implicit
cast with `UncheckedDerivedToBase` will be generated:
```
void foo() {
Base b;
Derived d;
std::move(d);
d = b;
}
```
AST for `d = b`'s `d`:
```
|-ImplicitCastExpr <col:3> 'GH62206::Base' lvalue <UncheckedDerivedToBase (Base)>
| `-DeclRefExpr <col:3> 'Derived' lvalue Var 0x1d11a400 'd' 'Derived'
```
This patch considers possible `implicitCastExpr` in the reinit matcher,

[PHIElimination] Clear stale LiveVariables AliveBlocks for undef PHI sources (#197764)
When PHI Elimination lowers a PHI with an undef source (e.g. from an
`IMPLICIT_DEF),` it skips the LiveVariables kill/AliveBlocks update
because the value is undefined. However, the source register's
AliveBlocks may still mark intermediate blocks as live-through from its
definition to the (now eliminated) PHI use. This causes MachineVerifier
failures in EXPENSIVE_CHECKS builds.
Fix by calling `recomputeForSingleDefVirtReg` on undef source registers
when their last PHI use on a CFG edge is eliminated, which correctly
clears the stale AliveBlocks entries.
Fixes the EXPENSIVE_CHECKS failure introduced by #196895.
ap24-auth-gssapi: Import apache2.4 module mod_auth_gssapi-1.6.5
This is a modern replacement for mod_auth_kerb (www/ap-auth-kerb),
built with the standardized GSSAPI rather than with the not-quite-so
standardized libkrb5.
[OpenACC] Fix invalid using inside of an openacc directive (#198058)
Bug report #197858 comes up with a reproducer where an invalid `using`
declaration checks the Scope it is in, and asserts if it isn't in a
DeclScope. Since all of the important directives that create scopes end
up causing a new scope anyway, this patch adds 'DeclScope' to the parse
scope for an OpenACC directive. This follows the guidance of the OpenMP
directives.
Fixes: #197858
[clang][bytecode] Fix wrong 'never produces a constant expression' diagnostic with static data members (#197881)
They can be initialized later, similar to extern variables.
thunderbolt: make code -Wunused clean
This change modifies code paths and uses `__diagused` to address `-Wunused`
issues that occur when `THUNDERBOLT_DEBUG` == `0`.

Downgrade mismatch when checking pack version minor from error to
warning.
With relative API stability in Godot 3.x, don't error when Godot bin
minor is less than pack file minor, warn instead. This is stop refusing
to run games that are built with HEAD and report higher minor version
than latest release.

[libc] Make cpp::byte alias-safe (#194171)
Change LIBC_NAMESPACE::cpp::byte from an enum-backed type to unsigned
char so libc’s raw-memory utilities and sorting code can legally access
object representations without violating C++ strict-aliasing rules.
