             Bug #: 56228
           Summary: [4.8 Regression] Indirect call fails to assemble
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: jakub@gcc.gnu.org
        ReportedBy: jakub@gcc.gnu.org
            Target: powerpc64-linux


short a[14] = { 1, 2 };
short b[15] = { 3, 4 };

int
foo ()
{
  void (*fna) (void) = (void (*) (void)) a;
  void (*fnb) (void) = (void (*) (void)) b;
  fna ();
  fnb ();
  return a[1] == b[1];
}

fails on ppc64, because call_indirect_aix64bit pattern uses "m" constraint for
64-bit loads instead of "Y" constraint.
