This is currently mimicking gfortran (https://gcc.gnu.org/onlinedocs/gfortran/Code-Gen-Options.html), which runs it at Ofast. We have not seen much benefits because Flang mostly allocates on the stack. @tblah is that right? https://github.com/llvm/llvm-project/pull/101701 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
