------- Comment #13 from hjl dot tools at gmail dot com 2008-08-02 15:19 ------- We should also test -O0. This code:
extern __inline __m128i __attribute__((__gnu_inline__, __always_inline__, __artificial__)) _mm_movpi64_epi64 (__m64 __A) { return _mm_set_epi64 ((__m64)0LL, __A); } extern __inline __m128i __attribute__((__gnu_inline__, __always_inline__, __artificial__)) _mm_move_epi64 (__m128i __A) { return _mm_set_epi64 ((__m64)0LL, _mm_movepi64_pi64 (__A)); } Why do we use _mm_movepi64_pi64 at all? _mm_movepi64_pi64 is an MMX intrinsic. It isn't necessary here. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36992
