Abstract

Circuitry and methods for implementing conditional fence instructions are described. In certain examples, a hardware processor (e.g., core) includes a branch predictor to predict one of a taken path and a not taken path for a conditional branch instruction; decoder circuitry to decode an instruction into a decoded instruction, the instruction comprising a field that indicates a condition to be set by execution of another instruction, and an opcode that indicates execution circuitry is to, in response to the condition being satisfied, implement an execution fence to delay execution of the instruction until prior instructions in program order execute and delay execution of instructions after the instruction in program order until the instruction executes; and the execution circuitry to execute the decoded instruction according to the opcode.
