In GCC 14, as I previously mentioned [here](https://discourse.llvm.org/t/the-priority-of-fno-fast-math-regarding-complex-number-calculations/84679/8), `-f[no-]cx-fortran-rules` seems to have a higher priority than other options and does not follow the "last-flag-wins" behavior. From my investigation, among the combinations of GCC options (`-f[no-]fast-math`, `-f[no-]cx-limited-range`, `-f[no-]cx-fortran-rules`), there are 7 cases where the behavior differs from "last-flag-wins". I have added these as tests for Case B and C in `range-warnings.c`. https://github.com/llvm/llvm-project/pull/149028 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
