MaskRay added a comment.
@ychen The GCC behavior ("omit" wins over "no-omit") makes sense because: in
the 4 states:
- 00) leaf retained, non-leaf retained
- 01) leaf retained, non-leaf omitted
- 10) leaf omitted, non-leaf retained
- 11) leaf omitted, non-leaf omitted
State 10) doesn't make sense. I think `-momit-leaf-frame-pointer` was designed
to omit leaf frame pointer when frame pointer is enabled
(`-fno-omit-frame-pointer` is in action). To make the other 3 states
representable, letting "omit" wins over "no-omit" (the current GCC behavior) is
the only sensible choice.
