Quantify provides timing information (profiling) foremost. The path
coverage info is more of a accumulated timing tree. For coverage, IBM
Rational has Purecov.

I never managed to get gprof (I asume that's what you mean) working with
GNAT 3.x series when it tasking was involved. Quantify does this.
Besides, the nice thing with Quantify is that you don't have to
recompile to profile (usefull if you suddenly get a few hours spare).

The GUI isn't important to me as such, but it is nice to be able to
scroll the source code where each line has a % or count of cycles next
to them. :)

http://kprof.sourceforge.net/ is an existing project, of course not in
GtkAda.
