This seems to be specific to the order of operations, which is related to "-funsafe-math-optimizations", but not necessarily the other three. If Clang has, and sets the same flags as GCC docs imply, we should only set the macro for that one flag. http://reviews.llvm.org/D12633 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
