Abstract

A code instrumentation method and a code instrumentation apparatus for instrumenting object codes of programs to enable memory access tracing. The code instrumentation method includes: identifying an object code block to be executed circularly in object codes; identifying at least one memory access instruction in the object code block where a memory address to be accessed during the circular execution of the object code block keeps unchanged; and inserting a routine for tracing the memory access to be executed by the at least one memory access instruction outside the object code block.
