34624 (shared_var_p): New inline function.
34625 (unshare_variable): Maintain cur_loc_changed and
34626 in_changed_variables fields. If var was in changed_variables,
34627 replace it there with new_var. Just copy cur_loc instead of

34647 (variable_was_changed): If dv had some var in changed_variables
34648 already, reset in_changed_variables flag for it and propagate
34649 cur_loc_changed over to the new variable. On empty var
34650 always set cur_loc_changed. Set in_changed_variables on whatever
34651 var is added to changed_variables.
34652 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
34653 Use shared_var_p. When removing loc that is equal to cur_loc,
34654 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
34655 end, don't set it to something else, just call variable_was_changed.
34656 (delete_slot_part): Use shared_var_p. When cur_loc equals to
34657 loc being removed, clear cur_loc and set cur_loc_changed.
34658 Set cur_loc_changed if all locations have been removed.
34659 (struct expand_loc_callback_data): New type.
34660 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
34661 allocated. Always create SUBREGs if simplify_subreg failed.
34662 Prefer to use cur_loc, when that fails and still in
34663 changed_variables (and seen first time) recompute it. Set
34664 cur_loc_changed of variables which had to change cur_loc and
34665 compute elcd->cur_loc_changed if any of the subexpressions used
34666 had to change cur_loc.
34667 (vt_expand_loc): Adjust to pass arguments in
34668 expand_loc_callback_data structure.
34669 (vt_expand_loc_dummy): New function.

34672 that weren't used for any other decl in current
34673 emit_notes_for_changes call call vt_expand_loc_dummy to update
34674 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
34675 first loc_chain location if NULL before. Always use just
34676 cur_loc instead of first loc_chain location. When cur_loc_changed
34677 is false, when not --enable-checking=rtl just don't emit any note.
34678 When rtl checking, compute the note and assert it is the same
34679 as previous note. Clear cur_loc_changed and in_changed_variables
34680 at the end before removing from changed_variables.
34681 (check_changed_vars_3): New function.
34682 (emit_notes_for_changes): Traverse changed_vars to call
