We would need the output of
make clean
make V=1
when you compile your project, so we can effectively see how the compiler is invoked.

Hi Paramesh,
One way to know if your app is really compiled with
-finstrument-functions is doing
$ objdump -d my_test_app | grep cyg
You would typically see something like this:
0000000000001250 <__cyg_profile_func_enter@plt>:
1250: ff 25 fa 2d 20 00 jmpq *0x202dfa(%rip) #
204050 <__cyg_profile_func_enter@GLIBC_2.2.5>
0000000000001260 <__cyg_profile_func_exit@plt>:
1260: ff 25 f2 2d 20 00 jmpq *0x202df2(%rip) #
204058 <__cyg_profile_func_exit@GLIBC_2.2.5>
14a8: e8 a3 fd ff ff callq 1250
<__cyg_profile_func_enter@plt>
16d8: e8 83 fb ff ff callq 1260
<__cyg_profile_func_exit@plt>
19c5: e8 86 f8 ff ff callq 1250
<__cyg_profile_func_enter@plt>
19e2: e9 79 f8 ff ff jmpq 1260
<__cyg_profile_func_exit@plt>
1a0d: e8 3e f8 ff ff callq 1250
<__cyg_profile_func_enter@plt>
If you see nothing, as Mathieu said, you can check the individual make
commands and see what flags are being used on the command line.

Sorry for the delayed response,
@Mathieu,
I have attached the build log. 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>
.....................

Please help me.
Thanks in Advance,
Paramesh

Hi,
I am trying to use Function Tracing for my application running in 32-bit
ARM Platform. I have added below lines in my makefile for enabling Trace
Data for function tracing
AM_CFLAGS += -g -O0 -finstrument-functions
AM_CXXFLAGS += -g -O0 -finstrument-functions
**(My App have both C && CPP files, So I added CFLAGS & CXXFLAGS).
I am running below commands,
$lttng create session1
$lttng enable-event -u -a --loglevel-only TRACE_DEBUG_FUNCTION
$lttng start
$LD_PRELOAD=liblttng-ust-cyg-profile.so.0.0.0 my_test_app
$lttng start
$babeltrace /home/root/lttng-traces/session1
Its showing nothing.
I tried with below event-enable command also. There is no data
$lttng enable-event -u -a --loglevel TRACE_DEBUG_FUNCTION
But If I use the command, "lttng enable-event -u -a" for enabling the
event, I am getting below output from babeltrace,

Note: I have changed the Target Name as 'ZZZ' and some of the library name
as 'xxx' in the above log for some confidential issues.
Please guide me where I am making mistake and Please give your input on how
to check the application compiled with function instrument information for
tracing. I verified that application compiled with debugging information,
by running gdb command. Below is the output of gdb command,
/usr/bin # gdb my_test_app

I am not sure whether it is compiled with finstrumentation information.
Thanks in Advance,
