Almost a year ago I tried to bring in the support for AMD's barcelona
chipset into our gcc. This actually filled a lot of holes in that were left
when similar intel support was brought in.
Unfortunately I had to revert rapidly such support as it broke building
some C++ ports even when it was not being used.
jkim@ did some cleanup of the support and the patch has been
gathering rust here:

The patch still applies cleanly and there is a good chance it will work
since there have been other fixes merged since the last time.
I did some basic testing and so far it works for me but I don't have
the specific chipset. Additional testing would be welcome.
I have to question the general direction of this work. We switched to Clang as
the default compiler for i386/amd64 some months ago and now you're working on
improving our base GCC especially for amd64? I don't really understand how
useful this is. It doesn't strike me as a good idea to see people working on
things that will eventually be replaced / removed.
It is probably a better use of time to work on getting the tree to build
with an out-of-tree gcc 4.7 or 4.8 instead. Why spend more effort on a
completely dead branch of gcc? Newer gcc's have better code generation,
support for more modern CPUs, and better diagnostics (including even
those controversial carets ;-).
FWIW, upstream gcc has a bug that affects ctfmerge and they have
been very slow to fix it. I submitted a bug report and a workaround
patch for ctfmerge to the Illumos guys but they have been very slow
to review it as well.
I do agree having out-of-tree compilers is important though; and
much preferable than carrying two compilers ;).
Pedro.
