- Redefines `DXILAttribute` to denote a function attribute, compatible
to how it was define in DXC/LLVM 3.7
- Fix how `DXILAttribute` is emitted to be a struct of set attributes
instead of an "or" of the enums
- Implement the lowering of `DXILAttribute` to LLVM function attributes
in `DXILOpBuilder.cpp`. A custom mapping is defined.
- Audit all current ops to specify the correct attributes consistent
with DXC. This is done here to allow for testing.
- Update testcases in `llvm/test/CodeGen/DirectX` of all ops with
attributes to match that attributes are set
- Update testcases of ops that had previously incorrectly set attributes
to check there is no attributes set
- Defines `DXILProperty` to denote the other type of attributes from DXC
used to query properties.
- Emit `DXILProperty` as a struct of set attributes.
- Updates `DXIL.td` to specify applicable `DXILProperty`s on ops

Note: `DXILProperty` was referred to as 'queryable attributes' in design
discussion. Changed to property to allow for better expression in
`DXIL.td`

 [DXIL] Add DXIL version-specific TableGen specification and implementation of DXIL Ops (#97593) 2024-07-30T21:25:58+00:00 S.

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. 
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.

[NFC] [DirectX] Prefix for intrinsics should be dx 2022-07-06T18:27:12+00:00 Chris Bieneman chris.bieneman@me.com 2022-07-06T17:18:09+00:00 e0b520865026828819a63d78f8f8bc77da34c34b `dxil` is an architecture supported by the DirectX backend. These intrinsics will likely be shared with other DirectX architectures like `dxbc`. Using a common prefix `dx` will make it more intuitive. Also the `dx` prefix is already set in the Triple, which causes intrinsics described here to be unmatchable via the ClangBuiltin mechanism.
