Emit an error if `-Zdwarf-version=1` is requested DWARF 1 is very different than DWARF 2+[^1] and LLVM does not really seem to support DWARF 1 as Clang does not offer a `-gdwarf-1` flag[^2] and `llc` will just generate DWARF 2 with the version set to 1[^3]. Since this isn't actually supported (and it's not clear it would be useful anyway), report that DWARF 1 is not supported if it is requested. Also add a help message to the error saying which versions are supported. cc #103057 [^1]: https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html#index-gdwarf [^2]: https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-gdwarf [^3]: https://godbolt.org/z/s85d87n3a |
