EZProfPlus

EZProfPlus is a simple profiler based on the ideas and code snippets by Daniel Reinhold as described in his Haiku Newsletter article. Unlike the original article, mine is a native BeOS GUI application. I made it above all for my own training.

Usage

Include trace.c in your project (included in the download).
Recompile your project with -finstrument-functions gcc option.
Start EZProfPlus and load your recompiled program with 'Load Program Image'.
Start your program, trace messages fly by.
Quit your program and examine the run-time statistics.

The profiler works by capturing messages sent by a client (profiled) program. The client sends messages by using gcc's instrument functions feature. The compiler generates calls to special tracing functions to keep track of function invocations and exits. A module trace.c with the appropriate instrument functions is described in the above mentioned article and included in the download.

The actual profiler stuff is in ezprofutil.cpp, which can be also compiled as a stand-alone command-line program by

gcc ezprofutil.cpp -o ezprof -DSTANDALONE

Requirements

BeOS R5 and compatibles. May work on Dano, Zeta, Haiku.
