I've just realised the above cannot be done for Visual Studio because it can't generate code for SSE4. The /arch option[1] only has selections for AVX, AVX2 and AVX512. This means Visual Studio binaries must remain where they are today. So what shall we do for MinGW? Both compilers (Clang and GCC) *can* generate SSE4 code. But is it worth having a different minimum for MinGW compared ti MSVC?
