Hey hey hey,
I tried to build a variant of vppsb and failed miserably
for lack of the __mm_testz_si128 symbol.
>From whence does that arrive on my doorstep?
I'm trying to figure out if vppsb needs to #define something new,
or #include something first, or if my system is suddenly missing
something assumed to be present and VPP cleverly allowed for
it to be missing while vppsb was less so?
Thanks,
jdl
