New Revision: 206952
URL: http://svn.freebsd.org/changeset/base/206952

Log:
  MFC assembler version of match functions for amd64 and i386(*).
  
  This gives approximately 15% improvement on compression case.
  
  (*) i386 assembler version is enabled ONLY when MACHINE_CPU have
  'i686' which is not default on FreeBSD/i386.  One can specify
  for instance CPUTYPE=pentium4 in /etc/make.conf to get this
  feature.
