; This function contains two selects which differ only by having reversed
; operand order. They are in fact equivalent, since the icmps that preceede
; them also are the same except for reversed conditions. SelectionDAG will
; discover this and return the other SELECT_CCMASK when the operands are
; canonicalized. This must be handled by SystemZDAGToDAGISel::Select, or
; instruction selection will fail.
