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?
