I don't understand how this pass fits into the SPIR-V lowering pipeline. Is this confusing [SPIR and SPIR-V](https://en.wikipedia.org/wiki/Standard_Portable_Intermediate_Representation)? SPIR being the format based on LLVM IR (although on an old version of LLVM 3.4)? SPIR-V being a custom [Khronos-defined format](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html). [While SPIR-V easily maps to LLVM IR](https://github.com/KhronosGroup/SPIRV-LLVM-Translator/blob/main/docs/SPIRVRepresentationInLLVM.rst), it is far from being a standardized mapping and the actual translation is usually handled by either [SPIRV-LLVM-Translator](https://github.com/KhronosGroup/SPIRV-LLVM-Translator) or the in-tree SPIR-V backend. Could you please comment on how this pass and the changes would fit into the current SPIR-V code generation flow through the SPIR-V backend? https://github.com/llvm/llvm-project/pull/131190 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
