            Bug ID: 109009
           Summary: Shrink Wrap missed opportunity
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jskumari at gcc dot gnu.org
  Target Milestone: ---

The following test case does not get shrink wrapped:

void bar (void);

long
foo (long i, long cond)
{
  if (cond)
    bar ();
  return i+1;
}

However, if we change the return statement from
   return i+1;
to
   return i;

then shrink wrapping kicks in.
