This directory contains code for x86-64 processors with fast
implementations of SSE operations, hence the name "fastsse".
Current processors that might benefit from this code are:
AMD K10
AMD Bulldozer/Piledriver/Steamroller/Excavator
Intel Nocona
Intel Nehalem/Westmere
Intel Sandybridge/Ivybridge
Intel Haswell/Broadwell
VIA Nano
Current processors that do not benefit from this code are:
AMD K8
AMD Bobcat
Intel Atom
Intel Conroe/Penryn is a border case; its handling of non-aligned
128-bit memory operands is poor. VIA Nano also have poor handling of
non-aligned operands.
