Chris Bieneman	e0b5208650	[NFC] [DirectX] Prefix for intrinsics should be dx ... `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.	2022-07-06 13:27:12 -05:00
Xiang Li	43dc319049	[DirectX] add thread/group id DXIL operations. ... Add DXIL operation for thread/group id operations. ID Name Description 93 ThreadId reads the thread ID 94 GroupId reads the group ID (SV_GroupID) 95 ThreadIdInGroup reads the thread ID within the group (SV_GroupThreadID) 96 FlattenedThreadIdInGroup provides a flattened index for a given thread within a given group (SV_GroupIndex) Also add llvm intrinsic which map to these intrinsics to DXIL operation.

python3kgae	435897b41d	[TableGen][DirectX] Add tableGen backend to generate DXIL operation for DirectX backend. ... A new tableGen backend gen-dxil-enum is added to generate enum for DXIL operation and operation class. A new file "DXILConstants.inc" will be generated when build DirectX target which include the enums. More tableGen backends will be added to replace manually written table in DirectX backend. The unused fields in dxil_inst will be used in future PR. Reviewed By: bogner Differential Revision: https://reviews.llvm.org/D125435	2022-06-14 17:31:58 -07:00
