18 # 1. Have a main() in main.c that calls an external function f2().
19 # 2. Have f2() implemented in f2.c.
20 # 3. Build the two files into one executable.
22 # 5. Open the executable inside gdb while having gdb in source layout.
23 # No source is found for the moment.
24 # 6. After a little bit of playing, we enter f2() and now the source
25 # layout must show the contents of f2.c.
26 # 7. Going back to main() shall result in no contents again.
28 # Check if start command is supported.
