3382 already, reset in_changed_variables flag for it and propagate
3383 cur_loc_changed over to the new variable. On empty var
3384 always set cur_loc_changed. Set in_changed_variables on whatever
3385 var is added to changed_variables.
3386 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
3387 Use shared_var_p. When removing loc that is equal to cur_loc,
3388 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
3389 end, don't set it to something else, just call variable_was_changed.
3390 (delete_slot_part): Use shared_var_p. When cur_loc equals to
3391 loc being removed, clear cur_loc and set cur_loc_changed.

3393 (struct expand_loc_callback_data): New type.
3394 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
3395 allocated. Always create SUBREGs if simplify_subreg failed.
3396 Prefer to use cur_loc, when that fails and still in

3398 cur_loc_changed of variables which had to change cur_loc and
3399 compute elcd->cur_loc_changed if any of the subexpressions used
3400 had to change cur_loc.
3401 (vt_expand_loc): Adjust to pass arguments in
3402 expand_loc_callback_data structure.
3403 (vt_expand_loc_dummy): New function.
3404 (emitted_notes): New variable.

3406 that weren't used for any other decl in current
3407 emit_notes_for_changes call call vt_expand_loc_dummy to update
3408 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
3409 first loc_chain location if NULL before. Always use just
3410 cur_loc instead of first loc_chain location. When cur_loc_changed
3411 is false, when not --enable-checking=rtl just don't emit any note.
3412 When rtl checking, compute the note and assert it is the same
3413 as previous note. Clear cur_loc_changed and in_changed_variables
3414 at the end before removing from changed_variables.
3415 (check_changed_vars_3): New function.
3416 (emit_notes_for_changes): Traverse changed_vars to call
