test/Driver should only test how the driver passes options to cc1. For inline assembly, you usually test that clangCodeGen correctly generates LLVM IR and the backend can lower asm. See `#77886` (x86 "Ws") for a good example (I carefully add tests. Many early-day asm patches might not add appropriate tests.) https://github.com/llvm/llvm-project/pull/79116 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
