20278 replace it there with new_var. Just copy cur_loc instead of

20299 already, reset in_changed_variables flag for it and propagate
20300 cur_loc_changed over to the new variable. On empty var
20301 always set cur_loc_changed. Set in_changed_variables on whatever
20302 var is added to changed_variables.
20303 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
20304 Use shared_var_p. When removing loc that is equal to cur_loc,
20305 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
20306 end, don't set it to something else, just call variable_was_changed.
20307 (delete_slot_part): Use shared_var_p. When cur_loc equals to
20308 loc being removed, clear cur_loc and set cur_loc_changed.
20309 Set cur_loc_changed if all locations have been removed.
20310 (struct expand_loc_callback_data): New type.
20311 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
20312 allocated. Always create SUBREGs if simplify_subreg failed.
20313 Prefer to use cur_loc, when that fails and still in
20314 changed_variables (and seen first time) recompute it. Set
20315 cur_loc_changed of variables which had to change cur_loc and
20316 compute elcd->cur_loc_changed if any of the subexpressions used
20317 had to change cur_loc.
20318 (vt_expand_loc): Adjust to pass arguments in
20319 expand_loc_callback_data structure.
20320 (vt_expand_loc_dummy): New function.

20323 that weren't used for any other decl in current
20324 emit_notes_for_changes call call vt_expand_loc_dummy to update
20325 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
20326 first loc_chain location if NULL before. Always use just
20327 cur_loc instead of first loc_chain location. When cur_loc_changed
20328 is false, when not --enable-checking=rtl just don't emit any note.
20329 When rtl checking, compute the note and assert it is the same
20330 as previous note. Clear cur_loc_changed and in_changed_variables
20331 at the end before removing from changed_variables.
20332 (check_changed_vars_3): New function.
20333 (emit_notes_for_changes): Traverse changed_vars to call
20334 check_changed_vars_3 on each changed var.
