- create a clang built-in in Builtins.td
- add semantic checking in SemaHLSL.cpp
- link the WaveReadLaneAt api in hlsl_intrinsics.h
- add lowering to spirv backend op GroupNonUniformShuffle
with Scope = 2 (Group) in SPIRVInstructionSelector.cpp
- add WaveReadLaneAt intrinsic to IntrinsicsDirectX.td and mapping
to DXIL.td
- add tests for HLSL intrinsic lowering to spirv intrinsic in
WaveReadLaneAt.hlsl
- add tests for sema checks in WaveReadLaneAt-errors.hlsl
- add spir-v backend tests in WaveReadLaneAt.ll
- add test to show scalar dxil lowering functionality
- note that this doesn't include support for the scalarizer to
handle WaveReadLaneAt will be added in a future pr
This is the first part #70104
