HLSL Working Group

2025-08-28 - HLSL Working Group Minutes

Propose a discussion topic by making an edit suggestion on the GitHub PR.

  • Discussion topics
    • Feature availablity for DXIL/SPIRV optional features
      • Maybe we should have a generalized approach that works for both DXIL optional features and SPIRV profiles and extensions.
      • Seems like general feeling is this would be an improvement over how DXC currently does things.
      • Action item: Chris B to write up a draft design to iterate with Steven on.
    • Quick updates:
      • A new Qualcomm Snapdragon X builder is coming online for the offload test suite.
      • Justin is aiming to have a PR up by the end of the week for constant buffer work.
      • Helena is reworking resource constructors and aims to get that in before Steven’s work on resource counters.
      • Farzon noted that we will need SPIRV backend legalization for vectors larger than 4 elements because some optimizations generate them.
