Test gcc.dg/uninit-4.c has failed on powerpc64-unknown-linux-gnu with -m64
since 2004-12-17 for a bogus uninitialized variable warning. No other target
for which test results have been reported for the last few days gets this
failure. The change is with this patch:
2004-12-17 Diego Novillo <dnovillo@redhat.com>
tree-optimization/18501
* tree-optimize.c (init_tree_optimization_passes): Run
pass_late_warn_uninitialized before the last DCE run.
The following testsuite changes were made at the same time:
2004-12-17 Diego Novillo <dnovillo@redhat.com>
* gcc.dg/pr18501.c: New test.
* gcc.dg/uninit-5.c: XFAIL.
* gcc.dg/uninit-9.c: XFAIL.
This is probably low priority, but I wanted a PR to reference when I mark
uninit-4.c XFAIL for { powerpc64*-*-* && lp64 }. (The new XFAILs for the
other tests don't have such references to PRs.)

It also fails on powerpc-darwin with -m64 too. So maybe xfailing it for powerpc*-*-* && lp64 would
be a better idea.

Diego, can this PR be closed as fixed?
Test gcc.dg/uninit-4.c started to XPASS with this patch from dnovillo:
http://gcc.gnu.org/ml/gcc-cvs/2005-05/msg00529.html
On the same day, test uninit-9.c also started to XPASS on:
hppa2.0w-hp-hpux11.11
hppa2.0w-hp-hpux11.*
hppa64-hp-hpux11.*
i686-pc-cygwin
i686-pc-linux-gnu
ia64-unknown-linux-gnu
mips-sgi-irix6.5
powerpc64-unknown-linux-gnu
powerpc-apple-darwin7.4.0
powerpc-ibm-aix5.2.0.0
s390-ibm-linux-gnu
x86_64-unknown-linux-gnu
I'd like to remove the xfail for these two tests and close this PR.

Yes. Apologies for not having done this before. The
uninitialized warning machinery needs to be re-designed, though.
Right now, we are at the mercy of whether certain passes were
done in some specific order.
Diego.
