# mmx : 'mmx_funcs.c',
# sse : 'sse_funcs.c',
# sse2 : 'sse2_funcs.c',
# <etc>
# configuration : cdata, # adds HAVE_XXX
# compiler : cc)
#
# and then have a target that uses the result in links_with.
# The following headers need to be added. Also Thumb and Altivec.
#<wmmintrin.h> AES
#<zmmintrin.h> AVX512
