| 16 | # Test unwinding when we have a frame inlined in the outer frame (in the sense | |
| 17 | # of frame.c:outer_frame_id). | |
| 18 | # | |
| 19 | # The conditions required to reproduce the original issue are: | |
| 20 | # | |
| 21 | # 1. Have an outer frame whose DWARF CFI explicitly says that the frame return | |
| 22 | # address is undefined. | |
| 23 | # 2. A frame inlined in this other frame. | |
| 24 | # | |
| 25 | # Because of (1), the test has to be written in assembly with explicit CFI | |
| 26 | # directives. | |
