[Bug libc/13583] AVX check not done correctly for strcasecmp


http://sourceware.org/bugzilla/show_bug.cgi?id=13583

--- Comment #2 from Ulrich Drepper <drepper.fsp at gmail dot com> 2012-01-26 14:48:35 UTC ---
Actually, strcmp cannot have problems since the code only uses the AVX
instruction encoding, not the YMM registers.  Therefore any problem in that
area must have a completely different reason.  There is code which potentially
uses the YMM registers and I added protection there.
