21560 (shared_var_p): New inline function.
21561 (unshare_variable): Maintain cur_loc_changed and
21562 in_changed_variables fields. If var was in changed_variables,
21563 replace it there with new_var. Just copy cur_loc instead of
21564 resetting it to something else.

21568 of their DEBUG_EXPR_TREE_DECLs.
21569 (canonicalize_loc_order_check): Verify that cur_loc is NULL
21570 and in_changed_variables and cur_loc_changed is false.

21573 (variable_merge_over_src): Don't call variable_canonicalize.

21583 (variable_was_changed): If dv had some var in changed_variables
21584 already, reset in_changed_variables flag for it and propagate
21585 cur_loc_changed over to the new variable. On empty var
21586 always set cur_loc_changed. Set in_changed_variables on whatever
21587 var is added to changed_variables.
21588 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
21589 Use shared_var_p. When removing loc that is equal to cur_loc,
21590 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
21591 end, don't set it to something else, just call variable_was_changed.
21592 (delete_slot_part): Use shared_var_p. When cur_loc equals to
21593 loc being removed, clear cur_loc and set cur_loc_changed.
21594 Set cur_loc_changed if all locations have been removed.
21595 (struct expand_loc_callback_data): New type.
21596 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
21597 allocated. Always create SUBREGs if simplify_subreg failed.
21598 Prefer to use cur_loc, when that fails and still in
21599 changed_variables (and seen first time) recompute it. Set
21600 cur_loc_changed of variables which had to change cur_loc and
21601 compute elcd->cur_loc_changed if any of the subexpressions used
21602 had to change cur_loc.
21603 (vt_expand_loc): Adjust to pass arguments in
21604 expand_loc_callback_data structure.
21605 (vt_expand_loc_dummy): New function.
21606 (emitted_notes): New variable.
21607 (emit_note_insn_var_location): For VALUEs and DEBUG_EXPR_DECLs
21608 that weren't used for any other decl in current
21609 emit_notes_for_changes call call vt_expand_loc_dummy to update
21610 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
21611 first loc_chain location if NULL before. Always use just
21612 cur_loc instead of first loc_chain location. When cur_loc_changed
21613 is false, when not --enable-checking=rtl just don't emit any note.
21614 When rtl checking, compute the note and assert it is the same
21615 as previous note. Clear cur_loc_changed and in_changed_variables
21616 at the end before removing from changed_variables.
21617 (check_changed_vars_3): New function.
21618 (emit_notes_for_changes): Traverse changed_vars to call
21619 check_changed_vars_3 on each changed var.
