Subject: gallium: GCC 4.9 allows to include tmmintrin.h without -msse3.
X-Git-Tag: upstream/17.1.0~17016
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb643db30e1bdf5171d0a012674016c317925b6e;p=platform%2Fupstream%2Fmesa.git

gallium: GCC 4.9 allows to include tmmintrin.h without -msse3.

Fixes build with MinGW x86_64 build with GCC 4.9, due to conflicting
definition _mm_shuffle_epi8 of u_sse.h and system headers.

Trivial.
