I have added a test in this case. `-fno-alias-analysis` takes precedence over `-Ofast` no matter their order. I don't think there is anything in clang that is equivalent to `-f[no-]alias-analysis`. These flags were added to flang so we could upstream alias analysis without enabling it by default. I would like to keep them after enabling by default in case alias analysis leads to any regressions. https://github.com/llvm/llvm-project/pull/73111 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
