Abstract
An apparatus comprises at least one register rename table structure comprising rename entries for indicating register mappings between architectural registers and corresponding physical registers, and register rename circuitry to update the register mappings indicated by the rename entries. Rename entries corresponding to at least one set of architectural registers support a cleared-register encoding. In response to an operation specifying a source architectural register for which a corresponding rename entry is set to the cleared-register encoding, the register rename circuitry controls the processing circuitry to process that operation with a source operand corresponding to the source architectural register being treated as having a predetermined value. In response to detection of a register clearing event indicating that at least one set of architectural registers is to be treated as having been cleared to the predetermined value, the register rename circuitry sets rename entries corresponding to the at least one set of architectural registers to the cleared-register encoding.
