2026-03-12 - HLSL Working Group Minutes

• Discussion topics
  • @s-perron mentioned that llvm/offload-test-suite#756 has been merged, adding depth texture support for the test suite for SPIR-V.
  • @icohedron mentioned llvm/wg-hlsl#394, a proposal to move HLSL library function definitions into tablegen, rather than implementing the header entirely by hand.
  • @farzonl pointed out that we’re getting quite a few PRs from folks outside of the meeting, and reminded people to watch for these so that they get good and prompt reviews.
  • @bogner pointed out that the vector elementwise-alignment datalayout specifier is now available as of llvm/llvm-project#180617. He’s implementing this for DirectX but would like help for the SPIR-V side.
  • @s-perron about the status around llvm/llvm-project#183367. @bogner pointed out that we’d like to be consistent between DirectX and SPIR-V here if possible, but if not we should follow @s-perron’s suggestion to convert the “unbounded” value when processing the intrinsic itself for SPIR-V.
  • @s-perron reminded everyone that when writing Vulkan specific tests, the flags to spirv-val need to be set appropriately so that it doesn’t run its validation under the wrong environment.
