3387 already, reset in_changed_variables flag for it and propagate
3388 cur_loc_changed over to the new variable. On empty var
3389 always set cur_loc_changed. Set in_changed_variables on whatever
3390 var is added to changed_variables.
3391 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
3392 Use shared_var_p. When removing loc that is equal to cur_loc,
3393 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
3394 end, don't set it to something else, just call variable_was_changed.
3395 (delete_slot_part): Use shared_var_p. When cur_loc equals to

3400 allocated. Always create SUBREGs if simplify_subreg failed.
3401 Prefer to use cur_loc, when that fails and still in

3403 cur_loc_changed of variables which had to change cur_loc and
3404 compute elcd->cur_loc_changed if any of the subexpressions used
3405 had to change cur_loc.
3406 (vt_expand_loc): Adjust to pass arguments in
3407 expand_loc_callback_data structure.

3413 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
3414 first loc_chain location if NULL before. Always use just
3415 cur_loc instead of first loc_chain location. When cur_loc_changed
3416 is false, when not --enable-checking=rtl just don't emit any note.
3417 When rtl checking, compute the note and assert it is the same
3418 as previous note. Clear cur_loc_changed and in_changed_variables
3419 at the end before removing from changed_variables.
3420 (check_changed_vars_3): New function.
