Hello.
Following small patch set targets $subject, where we ICE if someone
uses #pragma GCC target ("arch=generic"). My attempt is to not to
create a new target optimization node in case of a wrong value
of march string. Such approach does not generate multiple errors.
Apart from that, I also improved i386 option handling as mentioned
in: [1]
Patch bootstraps and survives regression tests on powerpc64le-unknown-linux-gnu.
Ready for trunk?
Thanks,
Martin
