I'm running some C code on the device and trying to figure out what I can do to make it faster. Unfortunately, I'm having trouble figuring out how to get the information I need from the tools available.
In this case, 99.7% of the time spent is in "hidden (pdpathfinder.c:568". Is this part of the API? Is there a way to tell where I'm calling this code from? Something like stack sampling would be really nice or, failing that, some of the source for the internal libraries would really help with debugging / profiling.
