           Summary: ICE in rs6000_emit_le_vsx_store, at
                    config/rs6000/rs6000.c:10367
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal

  Target Milestone: ---

Following code snippet ICEs:

$ cat ice.ii
void _setjmp ();
void a (unsigned long *);
void
b ()
{
  for (;;)
    {
      _setjmp ();
      unsigned long args[9]{};
      a (args);
    }
}

$ ./xgcc -B. ice.ii -O1 -fstack-protector-strong -c
during RTL pass: reload
ice.ii: In function ‘void b()’:
ice.ii:12:1: internal compiler error: in rs6000_emit_le_vsx_store, at
config/rs6000/rs6000.c:10367
