26662 replace it there with new_var. Just copy cur_loc instead of

26683 already, reset in_changed_variables flag for it and propagate
26684 cur_loc_changed over to the new variable. On empty var
26685 always set cur_loc_changed. Set in_changed_variables on whatever
26686 var is added to changed_variables.
26687 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
26688 Use shared_var_p. When removing loc that is equal to cur_loc,
26689 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
26690 end, don't set it to something else, just call variable_was_changed.
26691 (delete_slot_part): Use shared_var_p. When cur_loc equals to

26695 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
26696 allocated. Always create SUBREGs if simplify_subreg failed.
26697 Prefer to use cur_loc, when that fails and still in

26699 cur_loc_changed of variables which had to change cur_loc and
26700 compute elcd->cur_loc_changed if any of the subexpressions used
26701 had to change cur_loc.
26702 (vt_expand_loc): Adjust to pass arguments in

26709 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
26710 first loc_chain location if NULL before. Always use just
26711 cur_loc instead of first loc_chain location. When cur_loc_changed
26712 is false, when not --enable-checking=rtl just don't emit any note.
26713 When rtl checking, compute the note and assert it is the same
26714 as previous note. Clear cur_loc_changed and in_changed_variables
26715 at the end before removing from changed_variables.
