Except that at the assembly level you cannot guess which switches were
passed to gas. You may try to guess with cpp, but it isn't able to get at
whatever is passed with "-Wa". Also you have to reflect all the
conditional paths from the "asm" sections of specs in the "cpp" ones,
which is fragile.
Pretty tough at the moment, I'd say.
