GCC 4.6.1 Release Candidate available from gcc.gnu.org

GCC 4.6.1 Release Candidate available from gcc.gnu.org

[Jakub Jelinek]

The first release candidate for GCC 4.6.1 is available from

  ftp://gcc.gnu.org/pub/gcc/snapshots/4.6.1-RC-20110620

and shortly its mirrors.  It has been generated from SVN revision 175201.

I have so far bootstrapped and tested the release candidate on
x86_64-linux and i686-linux.  Please test it and report any issues to
bugzilla.

If all goes well, I'd like to release 4.6.1 early next week.

They aren't really regressions from 4.6.0 but on SPARC/Solaris we have:

FAIL: gcc.dg/vect/pr48377.c execution test (you know what I mean)

FAIL: g++.dg/cpp0x/lambda/lambda-eh2.C execution test (PR c++/49260)

and on SPARC64 we have an ACATS failure:

FAIL:   c94007a


The ACATS failure is a reorg.c bug, for which I have a straightforward fix, but 
I think I should first ask if you're interested in it for 4.6.1 before wasting 
CPU cycles. ;-)

For this a patch is awaiting review, but it is a testsuite only issue,
so not a blocker.

I guess it depends on how risky the patch is, while reorg.c affects only a
few targets, they still include some primary targets.  If it is not a
regression from 4.6.0 and the fix isn't very obviously safe, it would probably be
better to postpone it for 4.6.2 (though, I think CPU cycles wouldn't be
wasted by preparing a fix for 4.6.2).

I think it is as obviously safe as a reorg.c patch can be so I'm going to test 
it (on the branch) and post it afterward, but it will be your call of course.

Are these regressions from 4.6.0 release?  If not, they don't look like
4.6.1 release blockers.

It bootstraps C, C++ and Fortran in a ARM Cortex-A9 and ARMv5TE
configuration.  The test results are here:

 http://gcc.gnu.org/ml/gcc-testresults/2011-06/msg02633.html

with more detail here:

Ramana or Richard, could you have a read over the results please?
