I think we should raise the baseline to include the byte-word extension (BWX) which I think would be EV56. In addition to giving some optimisations generally to libc it would eliminate a class of unaligned access bugs across the archive where gcc performs an optimisation based on a flawed determination that certain alignment exists in the memory access of a byte or 16-bit word.
