Microsoft Visual Studio 2012 Internal Compiler Error
Raw
gistfile1.txt
// Put this in a .c file and cl it to cause the internal compiler error. It also crashes as a .cpp, but you have to extern "C" the declarations.
typedef union __m128 {float m128_f32[4];} __m128;
__m128 _mm_load_ps(float const *);
void _mm_store_ps(float *, __m128);
void main(void) {_mm_store_ps(0, _mm_load_ps(0));}
