Subject: Fix a bug in xmmintrin.h.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a67eeb084e52c1c3e64a77be5af952f2a0c9e8c8;p=clang

Fix a bug in xmmintrin.h.

The last step of _mm_cvtps_pi16 should use _mm_packs_pi32, which is a function
that reads two __m64 values and packs four 32-bit values into four 16-bit
values.
