Multi-condition branch instruction for conditional branch operations

Abstract

Various embodiments of the present disclosure relate to the conditional execution of program code. In an example embodiment, a system including instruction fetch circuitry, decoder circuitry, and multi-condition branch circuitry is provided. The instruction fetch circuitry is configured to fetch a multi-condition branch instruction (MCBI) from memory. The MCBI identifies multiple status registers and multiple branch destinations. The multiple status registers of the MCBI are representative of registers which hold results of multiple condition evaluations, such that each status register corresponds to a different one of the multiple condition evaluations. Similarly, the multiple branch destinations of the MCBI also correspond to a different one of the multiple condition evaluations. The instruction fetch circuitry provides the MCBI to the decoder circuitry. In response, the decoder circuitry is configured to cause the multi-condition branch circuitry to execute the multi-condition branch instruction.
