gcc -Wl,linker-option

gcc -Wl,-option passes the linker specific option -option to the linker.

prog.c

I am going to compile and link the following simple program: 
#include <stdio.h>

int main() {
    return 0;
}
Github repository about-gcc, path: /options/Wl/prog.c

Makefile

When I link the program, we want to pass the -t flag to the linker so that it traces the names of the input files that the linker processes.
This can be achieved by invoking gcc with -Wl,-t: 
a.out: prog.o
	@gcc -Wl,-t $^ -o $@

prog.o: prog.c
	@gcc -c $< -o $@
Github repository about-gcc, path: /options/Wl/Makefile

Output

The output of the -t option on my machine is:
