Also, as I understand it this change shouldn't affect gcc's SPEC benchmark scores, since they're typically done with -O3 or better.
It's not all about benchmark scores. I think most users compile at -O2 and they also won't understand why they get a performance drop on their code.
You say you doubt it affects performance. Based on what? Facts please, not guesses and hand-waiving...
