Hi,
Now I am working on ESP32 and want to do know which function used much CPU time.
When use -pg to compile project, the xtensa toolchain said: undefined reference to `_mcount'.
How can I know which function used much CPU time?
Thanks.

Hi yanbin,

Gprof support is in review at the moment, and should appear in master next week or so.
