guiand added a comment. This whole thing is a little unfortunate, but maybe a better substitution would be leaving `%clang` as referring to the pure clang binary, with default arguments. Then we can have a `%clang_cc` which may only be used for a standard C compiler invocation.
Returning to the main issue, adding a default argument to `%clang` breaks a number of tests. Generally these tests change the compiler mode such that a C compiler argument makes no sense. Consider `%clang -cc1`: this gets expanded to `clang -Xclang -disable-noundef-analysis -cc1`, which IIRC causes an error. This isn't a problem with something like `%clang_cc`, because a C compiler flag would always be valid for that expansion. IMO it's better to just one-and-done programatically add `-Xclang -disable-noundef-analysis` to all the tests' RUN lines. That way there are no hidden flags.
