About João Saffran

  • I work on HLSL language support in Clang.
  • I'm on the DirectX Shader Compiler team at Microsoft since 2024.
  • I am a contributor to Clang and DirectX, SPIR-V backends in LLVM.
  • Curated Contributions:
    • llvm/llvm-project:
      • Root Signature Support: Implemented Root Signature support in the DirectX backend.
      • HLSL intrinsics: Added matrix type overloads for HLSL intrinsics.
      • HLSL support to Vulkan: Added an opt flag to run the SPIR-V structurizer pass in isolation; Added support for hlsl instrinsics in vulkan.
    • microsoft/DirectXShaderCompiler:
      • auto type: Contributed to HLSL auto type deduction in DXC.
      • HLK tests: Extended HLK driver-compiler tests to validate Long Vector operations.
      • Vulkan SDK Release: Contributed fixes, test coverage and CI/CD pipelines to DXC Vulkan SDK releases.
    • microsoft/hlsl-specs:
      • Root Signature spec: Contributed to the formal specification of Root Signature syntax and semantics for the next HLSL language revision.
      • Vulkan SDK release spec: Contributed HLSL-to-SPIR-V behavior specifications aligned with the Vulkan SDK release cycle.
    • llvm/offload-test-suite:
      • HLSL intrinsics tests: Added end-to-end execution tests for HLSL intrinsics and language features.
      • Cross-IHV validation: Audited and fixed the test suite to validate shader correctness across hardware from AMD, Intel, and NVIDIA.
  • Before joining Microsoft, I was a compiler and HPC researcher:
