Abstract
A processor includes a front end to decode an instruction and pass the instruction to execution units with branch suffix information. The processor further includes execution units to execute the instruction and a retirement unit to retire the instruction. The instruction is to specify an operation to be conditionally executed based upon a branch suffix to identify previous execution. The processor further includes logic to, upon retirement of the instruction, determine the result of a series of branch operations preceding execution of the instruction, compare the result to the branch suffix information, allow execution and retirement of the instruction based on a determination that the result matches the branch suffix information, and generate a fault based on a determination that the result does not match the branch suffix information.
