No, the 128-bit versions of these C intrinsics are strictly for AVX versions of the instructions (eg, vcmpps). Example from the bug report: cmp = _mm_cmp_ps((__m128)a, (__m128)b, 8); We're currently emitting illegal SSE instructions like: cmpps $0x8, %xmm1, %xmm0 <--- anything over '7' is reserved/undef http://reviews.llvm.org/D21306 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
