Thanks for the report! Can you please tell me how OpenBLAS was built? I'm trying to replicate this, but I do not see a reference to `_QQmain` or the likes in the OpenBLAS library that I build on x86. https://github.com/llvm/llvm-project/pull/73124 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
