The existing code used ssse3, and because it isn't compiled in a separate file compiled with that, it is usually not used (that, of course, could be fixed...), whereas sse2 is always present at least with 64bit builds. This should be pretty much as fast as the pshufb version, albeit those code paths aren't really used on chips without llc in any case. v2: fix andnot argument order, add comments v3: use pshuflw/hw instead of shifts (suggested by Matt Turner), cut comments Reviewed-by: Matt Turner <mattst88@gmail.com> |
