Implement Matrix QueryAccumulatorLayout Builtin #7912

@V-FEXrt

Description

@V-FEXrt

Create __builtin_LinAlg_MatrixQueryAccumulatorLayout() and lower it to dx.op.matrixQueryAccumulatorLayout as specified in https://github.com/microsoft/hlsl-specs/blob/main/proposals/0035-linalg-matrix.md

Changes required:

  • If necessary, update the intrinsic definition in utils/hct/gen_intrin_main.txt
  • In lib/HLSL/HLOperationLower.cpp
    • Create a new lowering function TranslateLinAlgMatrixQueryAccumulatorLayout
    • Update the mapping table for IOP___builtin_LinAlg_MatrixQueryAccumulatorLayout from EmptyLower to TranslateLinAlgMatrixQueryAccumulatorLayout
  • Write frontend tests in tools/clang/test/SemaHLSL/hlsl/linalg/builtins/matrixqueryaccumulatorlayout
  • Update frontend tests in tools/clang/test/SemaHLSL/hlsl/linalg/builtins
  • If necessary, update the opcode definition in utils/hct/hctdb.py (be sure to check allowed stages)
  • Update codegen tests in tools/clang/test/CodeGenDXIL/hlsl/linalg/builtins
  • For complex ops, write codegen tests in tools/clang/test/CodeGenDXIL/hlsl/linalg/builtins/matrixqueryaccumulatorlayout

Note: The spec is not final therefore this issue may fall out of date. The spec is the source of truth and should be referenced during implementation.
