Hello,
I am trying to use -finstrument-function provided by gcc.(4.9.2).
It is large code base. i have defined a header file, and source file
containing declaration and definition of following functions...
__attribute__((no_instrument_function)) void __cyg_profile_func_enter
(void *this_fn, void *call_site);
__attribute__((no_instrument_function)) void __cyg_profile_func_exit
(void *this_fn, void *call_site);
and definitions as-->
void __cyg_profile_func_enter (void *this_fn, void *call_site)
{
printf("Function Entering : %p %p \n", this_fn, call_site);
}
void __cyg_profile_func_exit (void *this_fn, void *call_site)
{
printf("Function Exiting : %p %p \n", this_fn, call_site);
}
Problem:
When i compile source code without instrumentation, it compiles. But
with instrumentation, I get lot of errors "undefined Reference to
'symbols' . There is change in the linking process.
Does -finstrument-function changes the linking process. If yes, how?
Please help me, not much data available on net regarding the same..
