(In reply to comment #2) > Stack alignment isn't supported on Windows. Since this bug effectively prevents using 256bit AVX instructions when compiling for Windows using GCC, I was wondering if there are any plans to support the stack alignment. It seems that simply adding andq $-32, %rsp to the function prologue would fix this. Or would it be feasible to replace VMOVAPS by unaligned VMOVUPS when accessing the stack?
