Abstract
A data processing apparatus is provided that comprises rename circuitry for performing a register rename stage of a pipeline in respect of a stream of operations. Move elimination circuitry performs a move elimination operation on the stream of operations in which a move operation is eliminated and the register rename stage performs an adjustment of an identity of registers in the stream of operations to compensate for the move operation being eliminated and demotion circuitry reverses or inhibits the adjustment in response to one or more conditions being met.
