You haven't provided the preprocessed testcase, so it is hard to guess, but
generally, if you have say a static function and call it also from assembly,
you need __attribute__((used)) to prevent the compiler from using different
calling conventions. Otherwise, if the compiler can see all possible callers
(inline asm doesn't count, then you have to use the used attribute), it can
decide not to emit the function at all, or use whatever calling convention it
thinks are best for the function.
