[Bug tree-optimization/19833] New: bogus uninitialized variable warning for powerpc64

[janis at gcc dot gnu dot org]

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:

        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:

        * 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.)
