539 (shared_var_p): New inline function.
540 (unshare_variable): Maintain cur_loc_changed and

562 (variable_was_changed): If dv had some var in changed_variables
563 already, reset in_changed_variables flag for it and propagate
564 cur_loc_changed over to the new variable. On empty var
565 always set cur_loc_changed. Set in_changed_variables on whatever
566 var is added to changed_variables.
567 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
568 Use shared_var_p. When removing loc that is equal to cur_loc,
569 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
570 end, don't set it to something else, just call variable_was_changed.
571 (delete_slot_part): Use shared_var_p. When cur_loc equals to
572 loc being removed, clear cur_loc and set cur_loc_changed.

576 allocated. Always create SUBREGs if simplify_subreg failed.
577 Prefer to use cur_loc, when that fails and still in

579 cur_loc_changed of variables which had to change cur_loc and
580 compute elcd->cur_loc_changed if any of the subexpressions used
581 had to change cur_loc.
582 (vt_expand_loc): Adjust to pass arguments in
583 expand_loc_callback_data structure.

587 that weren't used for any other decl in current
588 emit_notes_for_changes call call vt_expand_loc_dummy to update
589 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
590 first loc_chain location if NULL before. Always use just
591 cur_loc instead of first loc_chain location. When cur_loc_changed
592 is false, when not --enable-checking=rtl just don't emit any note.
593 When rtl checking, compute the note and assert it is the same
594 as previous note. Clear cur_loc_changed and in_changed_variables
595 at the end before removing from changed_variables.
596 (check_changed_vars_3): New function.
597 (emit_notes_for_changes): Traverse changed_vars to call
598 check_changed_vars_3 on each changed var.
