The Project I am working is Yocto Project based build system. My App uses the shared object "libhw.so". So, it built first. As I said before,below are the flag I added AM_CFLAGS += -g -O0 -finstrument-functions AM_CXXFLAGS += -g -O0 -finstrument-functions From the log I found that "-finstrument-functions" flag included in compiling all the source files, ' libhw.la' file and 'my_test_app' binary, but not included for compiling 'libhw.so'. I am not sure why? My question is, as you see my shared object and binary includes following so's "libtinyalsa.so libexpat.so libbinder.so libutils.so libhwwrapper.so libhardware.so libcutils.so liblog.so". Are all these need to be compiled with finstrument flag. In that case, it will increase my workload, since some of them are custom build and some from the libs and each of them might have their own dependents. @gen, objdump doesn't support arm architecture. So, I used "arm-linux-gnueabi-objdump" tool. I could see cyg information to all my object files but I could not see for "libhw.so" and "my_test_app" files. cyg information of one of my source file, $ arm-linux-gnueabi-objdump -d libhw_la-hw_api.o | grep cyg 20: ebfffffe bl 0 <__cyg_profile_func_enter> 30: eafffffe b 0 <__cyg_profile_func_exit> 64: ebfffffe bl 0 <__cyg_profile_func_enter> a4: ebfffffe bl 0 <__cyg_profile_func_exit> ..................... ..................... 2548: ebfffffe bl 0 <__cyg_profile_func_exit> 258c: ebfffffe bl 0 <__cyg_profile_func_enter> 25d0: ebfffffe bl 0 <__cyg_profile_func_exit> 25e8: ebfffffe bl 0 <__cyg_profile_func_exit> Please help me.
