There is a page talking about enabling some simd, such as SSE2, AVX, AVX2
https://learn.microsoft.com/en-us/cpp/build/reference/arch-x86?redirectedfrom=MSDN&view=vs-2019

However, it does not mention how to enable other simd optimizations, e.g., SSE4.1, SSE4.2, SSE3
Is it possible to add a table/list for all the supported simd flags?

    The quickest and most direct resolution is to use the Feedback links at page bottom to make these suggestions.
