Abstract:
A method includes, in a processor that executes instructions of program code, monitoring the instructions in a segment of a repetitive sequence of the instructions so as to construct a specification of register access by the monitored instructions. In response to detecting a branch mis-prediction in the monitored instructions, the specification is corrected so as to compensate for the branch mis-prediction. Execution of the repetitive sequence is parallelized based on the corrected specification.
