[hint] sse2neon #57
Description
even if there is no plan to implement arm-instructions, it is moslty possible to use the sse2neon lib to emulate sse instructions on ARM.
So you can use vectorclass on ARM
i found some things to be defined before including the vectroclass.h
and a small change that has to be made to the instrset.h file.
it is working as far as i could test on apple M1 chips
maybe those changes can be directly applied to vectorclass due to a preprocesse like "VCL_USE_SSE2NEON"
cheers
/*
ARM compatible include of the vectorclass
on ARM/MAC the sse2neon lib will be imported
and some parameters for the vectorclass are prepared.
#IMPORTANT in vectorclass.h->instrset.h the cpuid function must be
hidden, since it is not compatible with ARM-compilers.
if missing, add the header-include check #if !defined(SSE2NEON_H)
to the function to hide it when compiling on ARM
remember that a dispatcher is not possible in this case.
