| 16 | # This test checks if gdb can handle missing source files gracefully. | |
| 17 | # Testing steps are: | |
| 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. | |
| 21 | # 4. Remove main.c. | |
| 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. | |
