Call counts are semantically different from other event types, which can be aggregated over the whole run e.g. for inclusive costs. And it makes no sense to compare call counts of different functions directly. Therefore call counts are differently handled than other costs. However, callgrind_annotate does show the call counts after function names of callers and callees of functions. For this, you have to ues e.g. "--tree=both": ... 120,470 < _dl_lookup_symbol_x (203x) [/lib/x86_64-linux-gnu/ld-2.23.so] 67,527 * do_lookup_x [/lib/x86_64-linux-gnu/ld-2.23.so] 22,407 > check_match (186x) [/lib/x86_64-linux-gnu/ld-2.23.so] 30,536 > dl_name_match_p (309x) [/lib/x86_64-linux-gnu/ld-2.23.so] ...
