ABSTRACT:
During compilation of a computer program, a branch instruction within the computer program is identified as having a characteristic (e.g., as being dependent upon unpredictable data) that influences the accuracy of a branch prediction for the branch instruction. Responsive to this identification, a compiler, again during compilation of the computer program, flags the branch instruction. During execution of the computer program, speculative execution of instructions is suppressed responsive to detection of the flagged branch instruction.
