5714 already, reset in_changed_variables flag for it and propagate
5715 cur_loc_changed over to the new variable. On empty var
5716 always set cur_loc_changed. Set in_changed_variables on whatever
5717 var is added to changed_variables.
5718 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
5719 Use shared_var_p. When removing loc that is equal to cur_loc,
5720 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
5721 end, don't set it to something else, just call variable_was_changed.
5722 (delete_slot_part): Use shared_var_p. When cur_loc equals to

5727 allocated. Always create SUBREGs if simplify_subreg failed.
5728 Prefer to use cur_loc, when that fails and still in

5730 cur_loc_changed of variables which had to change cur_loc and
5731 compute elcd->cur_loc_changed if any of the subexpressions used
5732 had to change cur_loc.
5733 (vt_expand_loc): Adjust to pass arguments in
5734 expand_loc_callback_data structure.
5735 (vt_expand_loc_dummy): New function.

5740 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
5741 first loc_chain location if NULL before. Always use just
5742 cur_loc instead of first loc_chain location. When cur_loc_changed
5743 is false, when not --enable-checking=rtl just don't emit any note.
5744 When rtl checking, compute the note and assert it is the same
5745 as previous note. Clear cur_loc_changed and in_changed_variables
5746 at the end before removing from changed_variables.
5747 (check_changed_vars_3): New function.
