Analyze linux program function calling status

[ debug linux optimize reverse-design ] 23 Oct 2020

function calling status tracing

use linux utilities valgrind (it also can analyze memory leakage) and kcachegrind ui tool to help us analyze function usage status

in ubuntu system, use the command to install these utilities:

sudo apt install kcachegrind valgrind

use the valgrind to generate report for calling usage status

valgrind --tool=callgrind <process>

after the command, the report file likes “callgrind.out." should be generated in your folder

the report document has lots of information, we can use the utility kcachegrind to help us show these information:

kcachegrind callgrind.out.<pid>
