Computer program product, a method for implementing the runtime instrumentation indirect sampling by address, and the system (runtime by the address instrumentation indirect sampling)

摘要

Provided to realize the run-time instrumentation indirect sampling by address. A one aspect of the present invention includes a method for realizing a run-time instrumentation indirect sampling by address. The method includes reading the sample point address, a plurality of sample point address from the array, the processor, associated with the plurality of sample point address to an instruction from the instruction stream being executed on a processor and including comparing the address. The method further comprises recognizing the sample points during execution of instructions associated with one of the matching address in the plurality of sample point address. Runtime instrumentation information is obtained from the sample point. Moreover, the method also includes storing the runtime instrumentation information as the runtime instrumentation program buffers reported group. .BACKGROUND 13
