[Valgrind-users] Callgrind: where do I find the list of event names?

[Dallman, J. <joh...@si...>]

I'm looking at using callgrind to replace an expensive Windows coverage tool,
and for some other work where the ideas are only part-formed.

The default callgrind run and callgrind_annonate display shows Ir events, but
I only need to count function entries. Is there a way to only collect those
and have callgrind run faster??

callgrind_annotate has the --show option to only show specific events, but I
can't find a list of event names to feed it. Where should I be looking?

To explain a bit, the reason I only need function entries is that we collect
coverage data on a per-function basis, for all our test cases, and then use
that to discover which test cases we need to run for changes to a given set
of functions.

The other task consists of trying to find the most-called functions, because
on a different platform, I am having to use a compiler option that adds a
small constant overhead to some, but not all, functions. If I can discover
the most-called functions, I can then find out if they are having the overhead
added by the compiler, and then try to revise them so that the compiler no
longer needs to do that.

thanks,
