30374 (shared_var_p): New inline function.
30375 (unshare_variable): Maintain cur_loc_changed and

30398 already, reset in_changed_variables flag for it and propagate
30399 cur_loc_changed over to the new variable. On empty var
30400 always set cur_loc_changed. Set in_changed_variables on whatever
30401 var is added to changed_variables.
30402 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
30403 Use shared_var_p. When removing loc that is equal to cur_loc,
30404 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
30405 end, don't set it to something else, just call variable_was_changed.
30406 (delete_slot_part): Use shared_var_p. When cur_loc equals to

30408 Set cur_loc_changed if all locations have been removed.
30409 (struct expand_loc_callback_data): New type.
30410 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
30411 allocated. Always create SUBREGs if simplify_subreg failed.
30412 Prefer to use cur_loc, when that fails and still in
30413 changed_variables (and seen first time) recompute it. Set
30414 cur_loc_changed of variables which had to change cur_loc and
30415 compute elcd->cur_loc_changed if any of the subexpressions used
30416 had to change cur_loc.
30417 (vt_expand_loc): Adjust to pass arguments in
30418 expand_loc_callback_data structure.

30422 that weren't used for any other decl in current

30424 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
30425 first loc_chain location if NULL before. Always use just
30426 cur_loc instead of first loc_chain location. When cur_loc_changed
30427 is false, when not --enable-checking=rtl just don't emit any note.
30428 When rtl checking, compute the note and assert it is the same
30429 as previous note. Clear cur_loc_changed and in_changed_variables
30430 at the end before removing from changed_variables.
30431 (check_changed_vars_3): New function.
30432 (emit_notes_for_changes): Traverse changed_vars to call
