527 (shared_var_p): New inline function.
528 (unshare_variable): Maintain cur_loc_changed and

535 of their DEBUG_EXPR_TREE_DECLs.
536 (canonicalize_loc_order_check): Verify that cur_loc is NULL

540 (variable_merge_over_src): Don't call variable_canonicalize.

542 removing loc that is equal to cur_loc, clear cur_loc,

544 (dataflow_set_remove_mem_locs): Use shared_var_p. Only

550 (variable_was_changed): If dv had some var in changed_variables
551 already, reset in_changed_variables flag for it and propagate
552 cur_loc_changed over to the new variable. On empty var
553 always set cur_loc_changed. Set in_changed_variables on whatever
554 var is added to changed_variables.
555 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
556 Use shared_var_p. When removing loc that is equal to cur_loc,
557 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
558 end, don't set it to something else, just call variable_was_changed.
559 (delete_slot_part): Use shared_var_p. When cur_loc equals to
560 loc being removed, clear cur_loc and set cur_loc_changed.
561 Set cur_loc_changed if all locations have been removed.
562 (struct expand_loc_callback_data): New type.
563 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
564 allocated. Always create SUBREGs if simplify_subreg failed.
565 Prefer to use cur_loc, when that fails and still in
566 changed_variables (and seen first time) recompute it. Set
567 cur_loc_changed of variables which had to change cur_loc and
568 compute elcd->cur_loc_changed if any of the subexpressions used
569 had to change cur_loc.
570 (vt_expand_loc): Adjust to pass arguments in
571 expand_loc_callback_data structure.
572 (vt_expand_loc_dummy): New function.
573 (emitted_notes): New variable.
574 (emit_note_insn_var_location): For VALUEs and DEBUG_EXPR_DECLs
575 that weren't used for any other decl in current
576 emit_notes_for_changes call call vt_expand_loc_dummy to update
577 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
578 first loc_chain location if NULL before. Always use just
579 cur_loc instead of first loc_chain location. When cur_loc_changed
580 is false, when not --enable-checking=rtl just don't emit any note.
581 When rtl checking, compute the note and assert it is the same
582 as previous note. Clear cur_loc_changed and in_changed_variables
583 at the end before removing from changed_variables.
584 (check_changed_vars_3): New function.
585 (emit_notes_for_changes): Traverse changed_vars to call
586 check_changed_vars_3 on each changed var.
587 (emit_notes_for_differences_1): Clear cur_loc_changed and

589 (emit_notes_for_differences_2): Clear cur_loc if new variable appears.
