For the HLSL FE, there are already a few ids represented using intrinsics (unfortunately they use the DXIL naming rather than the SPIR-V but that's another point). I extended on that, were there reasons to not pursue this ? > The reason for this is we wanted to make sure the final load/store to be > explicit, and possibly optimized-out. The intrinsic model will achieve the same thing for Inputs: they are modeled as pure, so 2 calls with the same parameters will be folded into 1 call and unused will be removed. For Outputs, I don't know (out of scope of what I'm trying to achieve). https://github.com/llvm/llvm-project/pull/143909 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
