[clang] fix transformation of subst constant template parameter nodes (#161029)

2025-09-28T01:30:06+00:00

This simplifies those transforms a lot, removing a bunch of workarounds
which were introducing problems.

The transforms become independent of the template instantiator, so they
are moved to TreeTransform instead.

Fixes #131342

This PR was already reviewed and approved at
https://github.com/llvm/llvm-project/pull/160777, but I accidentally
merged that into another PR, instead of main.

[clang] simplify placeholder type deduction for constant template parameters (#160439)

2025-09-28T00:59:53+00:00

This makes the deduction for dependent types operate in more similar
ways to the non-dependent one, such as when matching template template
parameters, making errors in those generate similar diagnostics to the
non-dependent ones. This also removes some superfluous implicit casts,
simplifying the resulting AST a little bit.

[VPlan] Allow multiple users of (broadcast %evl).

2025-09-27T20:47:54+00:00

CSE may replace multiple redundant broadcasts of EVL with a single
broadcast which may have more than 1 user. Adjust the verifier to allow
this.

Fixes a crash when building llvm-test-suite with EVL:

[GitHub][docker] Fix 'FromAsCasing' violation in CI dockerfile (#161017)

2025-09-27T20:39:35+00:00

Fixes https://docs.docker.com/reference/build-checks/from-as-casing/
which also gives warning when building container from command line:
```
=> WARN: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 1)

[VPlan] Mark VPInstruction::Broadcast as not reading/writing memory.

2025-09-27T19:48:42+00:00

This enables additional DCE/CSE opportunities and ensures that we don't
end up with multiple redundant users of a VPInstruction using EVL. It
fixes a verifier error in the added test_3_inductions test.

[clang-format][NFC] Rename a unit test

[MLIR][Python] add unchecked gettors (#160954)

2025-09-27T18:54:33+00:00

Some of the current gettors require passing locations (i.e., there be an
active location) because they're using the "checked" APIs. This PR adds
"unchecked" gettors which only require an active context.

[X86] matchVPMADD52 - only use 512-bit MADD52 on AVX512IFMA targets (#161011)

2025-09-27T16:43:58+00:00

If we have a AVX512 target capable of AVXIFMA but not AVX512IFMA then we must split 512-bit (or larger) types to 256-bits

Fixes #160928
