Author: Henrik Gramner <hen...@gramner.com> Committer: Derek Buitenhuis <derek.buitenh...@gmail.com> Date: Wed Sep 11 17:49:29 2013 +0200 x86inc: remove misaligned cpu flag Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether.
