Java stack machine execution kernel dynamic instrumentation

摘要

A method and system for performing dynamic instrumentation. At least some of the illustrative embodiments are methods comprising setting at least one monitor value (wherein the at least one monitor value is associated with a software monitoring handler), detecting a value within a register equal to the at least one monitor value, and executing the software monitoring handler based on the detecting.

1. A method comprising:
setting at least one monitor value, wherein the at least one monitor value is associated with a software monitoring handler; wherein the at least one monitor value indicates a location of an executable instruction of a first instruction set; wherein the software monitoring handler comprises instructions of a second instruction set and is to be executed in addition to the executable instruction; detecting a value within a register equal to the at least one monitor value; executing the software monitoring handler based on the detecting; executing the executable instruction; and overwriting at least one association in a table that associates the monitor value with the software monitoring handler.
