     1  This directory contains code for x86-64 processors with fast
     2  implementations of SSE operations, hence the name "fastsse".
     3  
     4  Current processors that might benefit from this code are:
     5  
     6    AMD K10
     7    AMD Bulldozer/Piledriver/Steamroller/Excavator
     8    Intel Nocona
     9    Intel Nehalem/Westmere
    10    Intel Sandybridge/Ivybridge
    11    Intel Haswell/Broadwell
    12    VIA Nano
    13  
    14  Current processors that do not benefit from this code are:
    15  
    16    AMD K8
    17    AMD Bobcat
    18    Intel Atom
    19  
    20  Intel Conroe/Penryn is a border case; its handling of non-aligned
    21  128-bit memory operands is poor.  VIA Nano also have poor handling of
    22  non-aligned operands.
