Hi,
I'm a new Valgrind / Callgrind user, and I'm trying to perform some profiling
of my code at source level, per C++ line of code.
My code is running on Android platform, it was built under ndk-build with debug
information included (-g option)
I activated valgrind with the following command in adb shell : valgrind
--tool=callgrind ...
It successfully activated my code and generated as output an 898 Kbyte file -
callgrind.out.6265
I then ran callgrind_annotate with the following command : callgrind_annotate
--auto=yes callgrind.out.6265 > callgrind.out.txt
When reading callgrind.out.txt I could find some of my code - actually 1
function, with its correct function name, under "Ir file:function", with a
count of 4,262,514
But no code-line level annotation was provided for this function (nor for any
other function).
When I tried to run callgrind_annotate without the --auto=yes option but
explicitly specifying my source file xyz.cpp, I got the following output :
No information has been collected for xyz.cpp
Does anyone have a clue regarding what can cause this behavior ?
Thanks,
Joel
