Thank you very much. I've read that section on cycles several times in the last few days, but I missed that. It would helped my Google searches and my eyes if the manual used the parens: "functions with names "func()", "func()'2", "func()'3" and so on..." Hopefully the manual's authors will read this and consider a clarification.
It's odd that I see some instances of foo()'2 without a corresponding foo(). Once example is memset()'2. That's probably why I suspected the notation referred to threads. I must have some cycle issues to explore further. Callgrind did identify some cycles, to my surprise. Again, thanks.

Or for all functions with |--separate-recs <http://valgrind.org/docs/manual/cl-manual.html#opt.separate-recs>=10|, but this will give you much bigger profile data files. In the profile data, you will see the recursion levels of "func" as the different functions with names "func", "func'2", "func'3" and so on. > Date: Wed, 30 Jun 2010 17:54:29 -0400 > From: Steven Meuse <[email protected]> > Subject: [Valgrind-users] KCachegrind notation- what is '2 in > "foo()'2"? > To: "'[email protected]'" > <[email protected]> > Message-ID: > <0a40042d85e7c84db443060ec44b3fd3253eef5...@dekaexchange07.deka.local> > Content-Type: text/plain; charset="us-ascii" > > I've searched Google and read all I could find.
