New Revision: 218895
URL: http://svn.freebsd.org/changeset/base/218895

Log:
  Backport svn r124339 from gcc 4.3 and add opteron-sse3, athlon64-sse3
  and k8-sse3 cpu-types for -march=/-mtune= gcc options.
  These new cpu-types include the SSE3 instruction set that is supported
  by all newer AMD Athlon 64 and Opteron processors.
  All three cpu-types are supported by clang and all gcc versions
  starting with 4.3 SVN rev 124339 (at that time GPLv2 licensed).
  
  PR:		gnu/154906
  Discussed with:	kib, kan, dim
  Obtained from:	gcc 4.3 (r124339, GPLv2 licensed)
  MFC after:	2 weeks
