Yes, it's how GCC works.

That's not acceptable.  We don't want to have to go through LLVM to fix issues
in GCC, especially for the platforms that LLVM doesn't support, i.e. most of
them.

Introducing such regressions is acceptable, provided that they can be quickly
fixed by the target maintainers.  Hence the "not acceptable" above.
