Subject testcase fails on powerpc64.

FAIL: gcc.dg/uninit-pred-9_b.c bogus warning (test for bogus messages, line 24)


Compiling standalone I see the following:

------- Comment #1 from davidxl at gcc dot gnu dot org  2010-07-14 04:12 -------

This seems to be specific to powerpc.

Could you attach the dump files with options:

-O2 -Wuninitialized -fdump-tree-cddce2 -fdump-tree-uninit-details

Thanks,

David
