intel intrinsic 8bit int to float

[Q139]

How to convert 8bit uint to float using most optimal AVX512 or older features?
Could be vectorized operation but i am new to intel intrinsics and cannot figure it out.

Isn't compiling with '-O2 -funroll-loops' enough? According to godbolt.org I would say yes. And when you're sure the target supports AVX instructions then add ' -mavx'
