Any ideas? Right now, I help myself out with C macros but the

Well, easy answer would be to write the loop iteration count statistics
to a log file, in a well-defined format that included the function
name, a line number, etc., then have another tool (or even
a shell script using grep intelligently) to pull the data back out and
present it in a more nicely formatted way.

Thank you for your ideas. But, as I understood your ideas, they all
expect the user to add some individual code for each loop under test.
That's what I'm currently doing, but for more complex applications
this becomes a tedious job. This was the reason why I was looking for
an automatic approach, something in the direction of gcov...

There are some tools that might be helpful. For example:
http://covtool.sourceforge.net/
I did a port of this to WIN32 if you want it. It's C++ specific.
It's also aimed at code coverage rather than profile per se, but it
would be a good starting point. It is pretty clever in that it parses
the source code files and does the instrumentation for you.


There are lots of similar things on SourceForge.
