OK.

The only usage of the word "event" in the callgrind.out file, apart from
the names of functions that happen to include "event", is in the header:

$ more callgrind.out.xyz
version: 1
creator: callgrind-3.8.1
pid: 7926
cmd:  xxxx.xxx

desc: I1 cache:

ob=(2) ???
fl=(2) ???
fn=(302) 0x00000000053fecd8
0 2

cfi=(8) ???
cfn=(304) 0x0000000000000df0
calls=1 0
...


That doesn't look as if there are any other events present, unless they're
called something different. I realise I've jumped to the conclusion that
calls are events, and this might not be true.

I guess I can write something to digest the .out file and produce call
counts from it.

thanks,
