ABSTRACT:
A compiler-directed speculative approach to resolve performance-degrading long latency events in an application is described. One or more performance-degrading instructions are identified from multiple instructions to be executed in a program. A set of instructions prefetching the performance-degrading instruction is defined within the program. Finally, at least one speculative bit of each instruction of the identified set of instructions is marked to indicate a predetermined execution of the instruction.
