  "textContent": "> So, building with -arch:AVX (or later) on a 32-bit target assumes you are not building true 32-bit binaries. I don't know why that would be desirable over 64-bit native.\n\nIt looks like things are even more complicated.\n\nThe SSE2 command extension appeared in the Intel Pentium 4 processor along with the EM64T. Therefore, the code that is compiled with the -arch:SSE2 key is no longer an ordinary 32-bit code. If you need a real i386, then there is key -arch:IA32. At the moment, I think there are no more systems left that do not support SSE2. The only question is AVX. Unfortunately, most “simple” even new processors do not support it.\n\n* * *",
