             Bug #: 52823
           Summary: [4.8 Regression] FAIL: gnat.dg/renaming5.adb
                    scan-tree-dump-times optimized "goto" 2
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dominiq@lps.ens.fr
                CC: ebotcazou@gcc.gnu.org, iains@gcc.gnu.org,

At revision 185913, the test gnat.dg/renaming5.adb fails on
x86_64-apple-darwin10:

FAIL: gnat.dg/renaming5.adb scan-tree-dump-times optimized "goto" 2

[macbook] f90/bug% grep goto renaming5.adb.149t.optimized 
    goto <bb 5>;
    goto <bb 4>;
  goto <bb 3>;

AFAICT the test passes at r185912 on s390-ibm-linux-gnu default (see
http://gcc.gnu.org/ml/gcc-testresults/2012-03/msg03204.html), but fails at
r185969 (see http://gcc.gnu.org/ml/gcc-testresults/2012-03/msg03354.html) as
well as on x86_64-unknown-linux-gnu (see
http://gcc.gnu.org/ml/gcc-testresults/2012-03/msg03405.html).

Note that gnat.dg/return3.adb fails on s390-ibm-linux-gnu default and
x86_64-unknown-linux-gnu:

FAIL: gnat.dg/return3.adb scan-assembler loc 1 6

I did not checked if a pr has already been filled for it or not. If not, since
I don't see it on darwin, I'll let a linux user fill it.
