* dummy-frame.h (dummy_frame_pop): Add prototype.
* dummy-frame.c: Include "observer.h".
(dummy_frame_push): Do not check for stale frames.
(dummy_frame_pop): New function.
(cleanup_dummy_frames): New function.
(_initialize_dummy_frame): Install it as inferior_created observer.
* frame.h (struct frame_id): Update comments.
(frame_id_inner): Remove prototype.
* frame.c (frame_id_inner): Make static. Add comments.
(frame_find_by_id): Update frame_id_inner safety net check to avoid
false positives for targets using non-contiguous stack ranges.
(get_prev_frame_1): Update frame_id_inner safety net check.
(frame_pop): Call dummy_frame_pop when popping a dummy frame.
* stack.c (return_command): Directly pop the selected frame.
* infrun.c (handle_inferior_event): Remove dead code.
* i386-tdep.c (i386_push_dummy_call): Update comment.

It's there, since all frame unwinders for a given target have to agree (within a certain margin) on the - definition of the stack address of a frame. Otherwise - frame_id_inner() won't work correctly. Since DWARF2/GCC uses the + definition of the stack address of a frame. Otherwise frame id + comparison might not work correctly. Since DWARF2/GCC uses the stack address *before* the function call as a frame's CFA. On the i386, when %ebp is used as a frame pointer, the offset between the contents %ebp and the CFA as defined by GCC. */ |
