Systems, apparatus, and methods are disclosed for generating pairs of conditional instructions corresponding to special predicate sequences from single instructions having a predicate. These pairs of conditional instructions update a destination register regardless of the truth or falsity of the predicate. The destination register is renamed to a new physical location. In this manner, register renaming can be used with predicate sequences to gain performance efficiencies and to overcome limitations of the prior attempted approaches.
