Numpy failing to enable CPU features

Compiling Numpy with MSVC entails the following output

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 INFO: ########### CLIB COMPILER OPTIMIZATION ########### INFO: Platform : Architecture: aarch64 Compiler : msvc CPU baseline : Requested : '+neon' Enabled : none Flags : none Extra checks: none CPU dispatch : Requested : 'max -xop -fma4' Enabled : none Generated : none

Requesting any permutation off features always return Enabled: none. You can try this with:

1 python setupy.py build --cpu-baseline="max"

In case you force clang with

1 python setup.py build --compiler=clang++

Numpy fails to compile as it doesn’t know how to compile with clang on platform NT.

This needs to be fixed as SIMD optimizations seem to be all disabled.
