            Bug ID: 65364
           Summary: FAIL: gcc.dg/uninit-19.c  (test for warnings, line 22)
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: danglin at gcc dot gnu.org

On hppa64-hp-hpux11.11 and other PIC targets, the expected warning
does not occur at the expected line number.  I believe the test
was already adjusted once.

/* { dg-warning "may be used uninitialized" "" { target nonpic } 13 } */^M
/* { dg-warning "may be used uninitialized" "" { target { ! nonpic } } 22 }
*/^M

The hppa64-hp-hpux11.11 target is always PIC and the warning occurs at line 13.

Confirmed on darwin.

See https://gcc.gnu.org/ml/gcc-patches/2015-02/msg00557.html for a patch and
https://gcc.gnu.org/ml/gcc-patches/2015-02/msg00737.html for some analysis for
darwin.

hppa64-hp-hpux* uses the default binding heuristics.  Maybe the nonpic 
test doesn't really
determine on which line the warning occurs.
