`^` can be interpreted as `^` in regex, which means the beginning. `$`, on the other side, suggests the end. In CCC_OVERRIDE_OPTIONS (clang/lib/Driver/Driver.cpp), `^` is to add an option at the beginning, but there is no `$`. There is `+`, whose meaning is slightly different. https://github.com/llvm/llvm-project/pull/117573 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
