Doesn't matter. If gcc passes "-mtune=i686" down to gas and thus the end
result doesn't match gcc's own documentation (and whole point of -mtune),
then it's still a gcc bug, even if it may not be a "cc1" bug. The fact
that "cc1" and "gas" are two different phases is pretty much irrelevant.
gcc calls them both.
But sure, if there are separate bugzillas, post it in both.
