; 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.
