Of course, this was the intent from the beginning of Sun's working with gcc for
AMD64. And, so far, all of the changes that can go into the mainline are
already in the mainline.
There are some changes that were needed for Solaris that the gcc mainline could
not accept (and probably will not be able to accept in the foreseeable future).
Thus, the ongoing need for the branch.

It cannot go into 4.2 apparently. I believe you're familiar with gcc policies.

should be backed by the opensolaris community as a whole): one off gcc
4.1 and another off gcc mainline.
branch of the mainline ?!
Such things are designed for new features and not for OS support.
'diff csl-sol210-3_4-branch gcc_343' should go into mainline, otherwise
we'll end up with 'sol' branches for every major gcc release ON care to
support.

As you can see Linux _never_ switched to plain gcc release.
New releases can be provided in distro, but kernel is alwasy based
on some branch of some release branch. Currently they are 4.0s and 4.1s
The former certainly does not happen, the latter does, as you can see from
regular bug reports about issues detected when building and running Linux
with gcc mainline.
Great ultimate goal.
The prerequisite for that is to have 'diff csl-sol210-3_4-branch gcc_343'
integrated into gcc trunk
should effectively target the Solaris 11 release, so baseing something on
GCC 4.0 for that release is a bad idea since that compiler will be
completely obsolete/unmaintained at that time.
I completely disagree. gcc is still patching 3.4 branch.
