sparc-linux results for 4.0.1 RC3

[Christian Joensson]

hmm, I get a few libstdc++ testsuite failuers....

http://gcc.gnu.org/ml/gcc-testresults/2005-07/msg00304.html

other than that, looks pretty fine.

Did you get them with 4.0.0 too?  If no, the libstdc++ folks will have to say 
whether they are really regressions (the testsuite harness has changed).

Yes, I would definitely encourage a little more analysis. I'm rather
puzzled. We have got very nice testsuites on sparc-solaris and on
*-linux, in general, and those failures certainly are not expected.
However, missing additional details, it's very difficult to guess: can
be almost anything, from a weirdness in the installed localedata to a
defect of the testsuite harness, to a code generation bug, to a latent
bug in the generic code of the library exposed only by that target, and
only now.

Probably we can exclude at least this first possibility: if I understand
well, everything related to glibc has not changed on the machine.

let me roll back binutils to and rebootstrap... or would you say I
could very well wait for 4.0.1 and test that?

Is the

FAIL: abi_check

failure expected?  Should config/abi/sparc-linux-gnu/baseline_symbols.txt be 
somehow updated?

Agreed, but were these tests simply run with the 4.0.0 testsuite?

Yes, probably we should concentrate on that failure. It's the most
strange, probably, because Benjamin and Jakub (certainly a Sparc expert)
updated the sparc-linux baseline around mid of June. Maybe we should
involve Jakub too in the discussion, at least to confirm that on his
sparc-linux machines abi_check doesn't fail.

Jakub?

I don't see these regression on Debian unstable, not exactly built
from the snapshot, but from CVS at the same date. Test results at

http://gcc.gnu.org/ml/gcc-testresults/2005-07/msg00280.html

However, there are 8 gfortran regressions, compared to 4.0.0:

FAIL: gfortran.dg/f2c_2.f90  -O0  execution test
FAIL: gfortran.dg/f2c_2.f90  -O1  execution test

The best would be if Christian could post (bzip2ed) readelf -Ws of
the libstdc++.so that fails the abi_check.

In fact, the excerpt from libstdc++.log that he sent privately doesn't
show the "check-abi Summary": as far as I know, abi_check can be
segfaulting (as is apparently happening for the other failures that he
reported).

sure, attached, this is with HJ's binutils-2.16.90.0.3-1 for linux
tarball test release rpm built for corona.

again, would you rather I backed off to a binutils-2.15.92.0.2-5?

I think it would be better to use Binutils releases when testing GCC releases, 
because that's what the users are supposed to do.  Binutils 2.16.x work fine 
on SPARC/Solaris so I presume they would work just fine on Linux too.

So, 4.0.0 testsuite posted at:

http://gcc.gnu.org/ml/gcc-testresults/2005-07/msg00344.html

What would you like me to do now?

I could back off binutils to binutils-2.15.92.0.2-5 and rebootstrap
both 4.0.0 and 4.0.1 RC3 for c++ only...
