[workstream] Resources #8

Open bogner opened 7 months ago

bogner commented 7 months ago

HLSL has buffer, texture, and sampler types that need to be lowered to resource representations when lowered to DXIL and SPIR-V.

Blocked on the design being finalized

bogner commented 6 months ago

For the middle/back end parts we need the following tasks:

[ ] llvm/llvm-project#91366
[ ] llvm/llvm-project#91406
[ ] llvm/llvm-project#92147
[ ] llvm/llvm-project#92148
[ ] llvm/llvm-project#91367
[ ] Introduce llvm.dx.rawBufferLoad/Store and lower them to rawBufferLoad/Store dxil ops
[ ] Implement llvm.dx.getDimensions and lower it to the dxil op
[ ] Implement llvm intrinsics for texture sampling and lower them to the dxil ops
[ ] Implement load/store (and other non-sampling) intrinsics for textures and lower them to dxil ops

I'll make a separate list for frontend parts

In clang, we'll need these tasks:

[ ] Introduce an HLSLResource builtin type (See llvm/llvm-project#90631)
[ ] llvm/llvm-project#95952
[ ] llvm/llvm-project#95956
[ ] llvm/llvm-project#84824
[ ] Implement builtins for texture sampling operations on HLSLResource types that will lower to the llvm intrinsics

@bogner - particle life seems to coincidentally be using alignment for structured buffers that work well, but @python3kgae suggests that we'll need to has plan for the vector alignment difference between hlsl(the element) and c++(the whole vector) . (This note to remind us to capture this somewhere in our plans).
