Employing sampled register values to infer memory accesses by an application

A system comprising:

• a processor;
• and
• a storage medium storing instructions which, when executed by the processor, cause the system to:
• obtain samples collected when executing an application, the samples comprising sampled register values;
• obtain application code of the application, the application code including sampled instructions that were executing when the samples were taken and other instructions of the application;
• iterate through the sampled instructions and the other instructions of the application while updating the sampled register values to obtain updated register values;
• identify memory accesses based at least on the other instructions and the sampled register values or the updated register values;
• and
• output the memory accesses.

A computer-readable storage medium storing instructions which, when executed by a computing device, cause the computing device to perform acts comprising:

• receiving user input specifying a sampling configuration for an application;
• configuring sampling of the application according to the sampling configuration;
• obtaining samples collected when executing the application according to the sampling configuration, the samples comprising sampled register values of a processor when the samples were collected;
• and
• identifying memory access characteristics of the application by analyzing the sampled register values, sampled instructions that were executing when the samples were collected, and other instructions of the application.
