Git commit 1c7c783ba262a9ce9d6e5c070f0d7fb85125cedd by GitHub (on behalf of Mayank) on 22/07/2026 at 11:25..
[Docs] Remove dead Phabricator link from DeveloperPolicy (#210934)

The Phabricator committing-a-change anchor no longer resolves since
Phabricator has been discontinued, so drop the reference and keep the
GitHub Issues guidance for linking reviewed/closed bugs.

Git commit 88840f264de6e0e6548219429ff62b3354db5210 by GitHub (on behalf of Ayokunle Amodu) on 22/07/2026 at 11:30..
[CIR][CUDA] Add support for scoped NVVM atomic builtins (#210863)

Adds codegen support for the block and system-scoped NVVM atomic
builtins: add, and, or, xor, min, max, inc and dec.

These are lowered to the corresponding CIR `cir.atomic.fetch` operations
and subsequently lowered to LLVM `atomicrmw` instructions.

This completes the third step of
https://github.com/llvm/llvm-project/issues/156680
This change is a follow-up to
https://github.com/llvm/llvm-project/pull/177854, following the release
branching, to ensure a one release-cycle deprecation period.

AMDGPU: Validate VOPD/VOPD3 physical source registers against operand RC (#196515)

Replace isVGPR checks with isValidVOPDSrc that validates physical source
registers against the actual combined VOPD/VOPD3 instruction's operand
register classes. Now we also validate operands for VOPD instructions.

Git commit 3369ddd384780f2ae60c3b20264735c2823d261c by GitHub (on behalf of Petar Avramovic) on 22/07/2026 at 12:10..
AMDGPU: Reland: Codegen for v_dual_dot2acc_f32_f16/bf16 from VOP3 (#196516)

For V_DOT2_F32_F16 and V_DOT2_F32_BF16 add their VOPDName and mark
them with usesCustomInserter which will be used to add pre-RA register
allocation hints to preferably assign dst and src2 to the same physical
register. When the hint is satisfied, canMapVOP3PToVOPD recognises the
instruction as eligible for VOPD pairing by checking if it is VOP2 like:
dst==src2, no source modifiers, no clamp, and src1 is a register.
Mark both instructions as commutable to allow a literal in src1 to be
moved to src0, since VOPD only permits a literal in src0.

Original patch had a bug where it did not check if physical src
registers match register class of appropriate operand in fullVOPD
instructions, check is now done via isValidVOPDSrc.

have been combined by earlier passes.
