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.
