[Bug java/41260] New: major regressions in libjava testsuite between 4.4.1 and gcc trunk

We have accumulated a large number of regressions in the libjava testsuite on
the x86_64-apple-darwin10 target in current gcc trunk compared to gcc 4.4.1...

http://gcc.gnu.org/ml/gcc-testresults/2009-09/msg00294.html
http://gcc.gnu.org/ml/gcc-testresults/2009-07/msg01866.html

Currently we have 133 failures on r151394 compared to only 14 for gcc 4.4.1.
These failures go back to at least 20090721 (137 failures). We will need to
perform a  manual regression hunt to try to bracket the revisions where these
were introduced after gcc 4.4 branched. Also we need to check the
x86_64-apple-darwin9 target for these regressions.

On i686-apple-darwin9 my latest regtest (r151159) shows:

Can you try testing x86_64-apple-darwin9 so I an focus on a regression hunt for
x86_64-apple-darwin10?

Dominique,
    Also if you are bothering to run the test suite on i686-apple-darwin9
periodically, you might as well shoot the results over to the gcc-testresults
mailing list (since Apple has never set up a i686-apple-darwin9 regress
server).

------- Comment #4 from howarth at nitro dot med dot uc dot edu  2009-09-05 01:24 -------
First round of regression hunting shows that r146781 (4/25/09) passes the
libjava like gcc 4.4.1 but r148013 (5/31/09) shows the additional 120+ libjava
failures.

------- Comment #10 from howarth at nitro dot med dot uc dot edu  2009-09-05 14:02 -------
Still running make check on r147995 but that revision appears to have caused
massive regressions in testsuite which aren't present in currently in gcc
trunk. Will look for any other test cases outside of libjava that are still
failing on x86_64-apple-darwin10 and started failing at r147995.

------- Comment #11 from howarth at nitro dot med dot uc dot edu  2009-09-05 14:27 -------
I just noticed PR 40304 which fixed regressions stack unwind from r147995. Will
move testing up to that revision to try to reduce the noise when looking for
residual regressions in current gcc trunk that may have been introduced at
r147995 (outside of libjava).

In r147989, we had no regressions in x86_64-apple-darwin10 in the g++
testsuite. However, in r148013 (which is after the fix for PR 40304), we have
the following g++ testsuite failures which still exist in gcc trunk on
x86_64-apple-darwin10...

Any idea of which of these would present the easy opportunity for debugging the

------- Comment #13 from howarth at nitro dot med dot uc dot edu  2009-09-05 15:32 -------
We also picked up failures in the gcc testsuite between r147989 and r1478013
of...

FAIL: gcc.dg/cleanup-12.c execution test
FAIL: gcc.dg/cleanup-8.c execution test

in case these are directly related to this regression.

Looking at the assembly output from the testcase...

the diff between that generated in r147989 and r1478013 is...
