That's news to me.

Seems Microsoft added AVX across the board to their compilers even for 32-bit targets which makes no sense to me (outside of just unifying compiler internals) as there are no 32-bit processors that support AVX , to my knowledge, since they were introduced in Sandy Bridge (Intel) and Bulldozer (AMD). Previously, it was also clear that this did nothing/should not do anything as the 32-bit targeting CL of MSVC did not offer -arch:AVX as a compile option. 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.
