If there is a way to determine whether the `-Woverriding-option` option is specified during driver processing (within `RenderFloatingPointOptions` in `Clang.cpp`), we might be able to implement this using `%select` or similar. However, I don't know how to determine if `-Woverriding-option` is specified. https://github.com/llvm/llvm-project/pull/144468 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
