Problems solved by technology

Unfortunately the benefits of conventional performance analysis tools are not available to all types of programs and functions.
Specifically, conventional performance analysis tools will not work properly with inlined functions.
Because conventional performance analysis tools correlate to the binary executable and the regular functions therein as opposed to the source code, and because conventional performance analysis tools do not take into account inlined function information, inlined functions can not be properly analyzed using existing performance analysis tools.

Abstract

A method and a system for examining an inlined function using a performance analysis tool are described. An inlined function is identified in computer code. Upon identification of the inlined function, and for example in response to executing a breakpoint associated with the inlined function, a performance analysis tool is used to perform desired task on the inlined function.

Description

TECHNICAL FIELD[0001]The present claimed invention relates to analysis of a computer program. More specifically, the present claimed invention relates to analyzing of inlined functions.BACKGROUND ART[0002]Over recent years, the computing community developed a strong set of tools and methods used to analyze and monitor run-time behavior of a program. Performance analysis tools include, for example, basis tools which allow for mapping of periodically taken snapshots during a program's execution to the program's source (e.g. sampling applications) and more complex tools which allow a broader range of program analysis (e.g. code instrumentation applications). Measurements such as basic-block coverage and function invocation counting can be accurately made using code instrumentation. One specific type of code instrumentation is referred to as dynamic binary instrumentation. Dynamic binary instrumentation allows program instructions to be changed on-the-fly. Additionally, dynamic binary i...
