4745 (shared_var_p): New inline function.

4747 in_changed_variables fields. If var was in changed_variables,
4748 replace it there with new_var. Just copy cur_loc instead of

4764 clear cur_loc and set cur_loc_changed. Don't recompute cur_loc here.

4767 (dataflow_set_different_1): Adjust variable_different_p caller.
4768 (variable_was_changed): If dv had some var in changed_variables
4769 already, reset in_changed_variables flag for it and propagate
4770 cur_loc_changed over to the new variable. On empty var
4771 always set cur_loc_changed. Set in_changed_variables on whatever
4772 var is added to changed_variables.
4773 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
4774 Use shared_var_p. When removing loc that is equal to cur_loc,
4775 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
4776 end, don't set it to something else, just call variable_was_changed.
4777 (delete_slot_part): Use shared_var_p. When cur_loc equals to
4778 loc being removed, clear cur_loc and set cur_loc_changed.
4779 Set cur_loc_changed if all locations have been removed.

4781 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
4782 allocated. Always create SUBREGs if simplify_subreg failed.
4783 Prefer to use cur_loc, when that fails and still in
4784 changed_variables (and seen first time) recompute it. Set
4785 cur_loc_changed of variables which had to change cur_loc and
4786 compute elcd->cur_loc_changed if any of the subexpressions used
4787 had to change cur_loc.
4788 (vt_expand_loc): Adjust to pass arguments in
4789 expand_loc_callback_data structure.
4790 (vt_expand_loc_dummy): New function.

4795 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
4796 first loc_chain location if NULL before. Always use just
4797 cur_loc instead of first loc_chain location. When cur_loc_changed
4798 is false, when not --enable-checking=rtl just don't emit any note.
4799 When rtl checking, compute the note and assert it is the same
4800 as previous note. Clear cur_loc_changed and in_changed_variables
4801 at the end before removing from changed_variables.
4802 (check_changed_vars_3): New function.
4803 (emit_notes_for_changes): Traverse changed_vars to call
4804 check_changed_vars_3 on each changed var.
