https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83402 --- Comment #11 from Bill Schmidt --- Conclusion is that we still need a fix to emmintrin.h along the lines of Steve's original two comments. Additionally, we need to fix trunk to complain about the out of range value, rather than quietly

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83402 --- Comment #9 from Steven Munroe --- I suggested fixing the emmintrin.h source for both eventually ... If you only fix AT11 then sometime later some will discover the difference and try fix it. And likely break it again. So fix AT immediately
