# This test checks if gdb can handle missing source files gracefully.
|
|
# Testing steps are:
|
|
# 1. Have a main() in main.c that calls an external function f2().
|
|
# 2. Have f2() implemented in f2.c.
|
|
# 3. Build the two files into one executable.
|
|
# 4. Remove main.c.
|
|
# 5. Open the executable inside gdb while having gdb in source layout.
|
|
# No source is found for the moment.
|
|
# 6. After a little bit of playing, we enter f2() and now the source
|
|
# layout must show the contents of f2.c.
|
|
# 7. Going back to main() shall result in no contents again.
