have complex pointer manipulation going on. This allows us to compile stuff like this: __m128i foo(__m128i x){ static const unsigned int c_0[4] = { 0, 0, 0, 0 }; __m128i v_Zero = _mm_loadu_si128((__m128i*)c_0); x = _mm_unpacklo_epi8(x, v_Zero); return x; } into: _foo: xorps %xmm1, %xmm1 punpcklbw %xmm1, %xmm0 ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41022 91177308-0d34-0410-b5e6-96231b3b80d8
