             Bug #: 56382

           Summary: FAIL: gcc.c-torture/compile/pr55921.c  (internal

                    compiler error)

          Severity: normal

         Component: middle-end

This is a problem extracting the first subreg from a SCmode value.  Thia

occurs during reload after the point where pseudos can be created but we

need a pseudo to extract the subreg.  The problem is SCmode is the same

size as DImode on this target, so the subreg can't be extracted by a move.



I marked this a middle-end bug as the documentation indicates that complex

values are handled by it.
