Abstract
A computer program product is provided for performing a method including: generating a test instruction stream of a program that includes a plurality of executable instructions; setting controls for a runtime-instrumentation process; simulating execution of the test instruction stream and sampling of the test instruction stream according to the controls, and storing simulated records associated with the sampling in a predicted collection buffer (PCB); accessing a program buffer of a processor, the program buffer storing records associated with sampling the test instruction stream according to the controls during execution of the test instruction stream by the processor; examining individual records in the program buffer to determine whether the individual records are valid and in proper sequence; and comparing the simulated records of the PCB and the records of the program buffer to validate the program buffer.
