I am not. I think we need to emit an error for -mwavefrontsize64 for HIP on gfx10+. If we do this as if -Werror=unsafe-wavefrontsize64 is the default, then users can use -Wno-error=unsafe-wavefrontsize64 I suppose. This seems like a weird use of -Wno-error though. https://github.com/llvm/llvm-project/pull/140185 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
