Description Stefan Sorensen 2002-07-16 22:38:12 UTC 
When compiling with -finstrument-functions, inlined functions are not
instrumented. Example with main calling a single (possibly) inlined function:

Without inlining:
$ gcc -finstrument-functions -o foo foo.c
$ ./foo
this_fn=0x8048404 call_site=0x420165c4
this_fn=0x80483d6 call_site=0x804842d

Both main and the called functions are instrumented.

With inlining:
$ gcc -O -finstrument-functions -o foo foo.c
$ ./foo
this_fn=0x8048404 call_site=0x420165c4

Only main has been instrumented.

gcc version: 3.1-7

Comment 2 Jakub Jelinek 2002-07-18 08:29:36 UTC 
This is the expected behaviour until -finstrument-functions is reimplemented
on AST (it is currently down at RTL level and since AST inlining was introduced
(for C++ in 2.96-RH, for C in 3.0) thus -finstrument-functions code doesn't
see inlined function boundaries any longer.
