What is your question or problem?

hi, I just found some difference between spirv-ll-tool and llvm-spirv -r on same spv kernel, why spirv-ll-tool exists ? will(can) it be replaced with https://github.com/KhronosGroup/SPIRV-LLVM-Translator ?

Hi, it's there for historical reasons, and this is something we'd hope to review in the future.

just make a initial support for llvm-spirv in

torch-nupu@b123420

mainly for issue

• spirv OpExtension SPV_KHR_non_semantic_info is not supported #614

I did not do a complete tests for this patch, It seems just works when not using llvm options O0 (some llvm passes need adapt)
