ZJIT: Read from correct CFP in forward fallback (#17875)
github/ruby/ruby · 2026-07-14
Lightweight frames need C code to use CFP_ISEQ(...).

The layout is shared by T_DATA objects and overflowed RObjects, so name the Rust variant after SHAPE_ID_LAYOUT_EXTENDED rather than one of i
Directly update existing instance variables in the fields object used by overflowed RObjects. Keep shape-changing writes on the generic path
Now share more code between the various cases: - Whether to copy all fields or just ivars - Whether to add or remove some capacity.
Followup: https://github.com/ruby/ruby/pull/17631 Now that complex `RObject` always have an IMEMO/fields, we no longer need to have an exte
By handling complex shapes in `rb_shape_rebuild` we can merge the two complex cases (when `src` is complex and when `dest` becomes complex).
It used to be that multiple paths would need to clear the generic ivar reference, but it's no longer the case.

Share more code with `rb_copy_generic_ivar`.
Doing it in `rb_gc_obj_changed_slot_size` is wrong as the object could still be moved back because of `invalidate_moved_plane`.
