Since we are using the Scalarizer pass in the backend we needed a way to
allow this pass to operate on Target intrinsics.
We achieved this by adding `TargetTransformInfo ` to the Scalarizer
pass. This allowed us to call a function available to the DirectX
backend to know if an intrinsic is a target intrinsic that should be
scalarized.
Update TableGen specification of DXIL Op records in DXIL.td per the
current design document.
- Facilitate specification of overloads, shader stage and attributes
predicated on DXIL Ops predicated DXIL version.
Implement functionality to consume in TableGen backend, DXILEmitter, the
above specification enhancements, and generate C++ code (in
(DXILOperations.inc) that represents properties of DXIL Ops, associated
type declarations and corresponding accessor functions.
Changes to DXIL Op Lowering pass to consume the DXIL Op representation
generated by the TableGen back end.
Add mtriple with the required shader model version to commandline of
tests.
This change implements #70074
- `hlsl_intrinsics.h` - add the `rsqrt` api
- `DXIL.td` add the llvm intrinsic to DXIL op lowering map.
- `Builtins.td` - add an hlsl builtin for rsqrt.
- `CGBuiltin.cpp` add the ir generation for the rsqrt intrinsic.
- `SemaChecking.cpp` - reuse the one arg float only checks.
- `IntrinsicsDirectX.td` -add an `rsqrt` intrinsic.
