How do we find out which object file is pulled in by the linker?

[prix prad]

Hi,
Two object files foo_1.o and foo_2.o each have the same function a()
defined and they
have no other functions. foo_1.o is in a library specified prior to
the library including
foo_2.o

The linker would pull in only foo_1.o in this case. What option can I
give to
gcc / ld to verify the above statement?

I basically looked at
http://stackoverflow.com/questions/715502/how-do-linkers-decide-what-parts-of-libraries-to-include

and

http://www.lurklurk.org/linkers/linkers.html#staticlibs

I understand the theory behind it, I am looking at how to get the
visible proof
w.r.t. what the linker is actually doing w.r.t. pulling in the object
files.

That's not a C question. You might try asking in gnu.gcc.help.
