6587 (shared_var_p): New inline function.

6590 replace it there with new_var. Just copy cur_loc instead of

6597 and in_changed_variables and cur_loc_changed is false.
6598 (variable_merge_over_cur): Clear cur_loc, in_changed_variables

6600 (variable_merge_over_src): Don't call variable_canonicalize.

6611 already, reset in_changed_variables flag for it and propagate
6612 cur_loc_changed over to the new variable. On empty var
6613 always set cur_loc_changed. Set in_changed_variables on whatever
6614 var is added to changed_variables.
6615 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
6616 Use shared_var_p. When removing loc that is equal to cur_loc,
6617 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
6618 end, don't set it to something else, just call variable_was_changed.
6619 (delete_slot_part): Use shared_var_p. When cur_loc equals to
6620 loc being removed, clear cur_loc and set cur_loc_changed.

6622 (struct expand_loc_callback_data): New type.
6623 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
6624 allocated. Always create SUBREGs if simplify_subreg failed.
6625 Prefer to use cur_loc, when that fails and still in

6627 cur_loc_changed of variables which had to change cur_loc and
6628 compute elcd->cur_loc_changed if any of the subexpressions used
6629 had to change cur_loc.
6630 (vt_expand_loc): Adjust to pass arguments in
6631 expand_loc_callback_data structure.
6632 (vt_expand_loc_dummy): New function.
6633 (emitted_notes): New variable.

6635 that weren't used for any other decl in current
6636 emit_notes_for_changes call call vt_expand_loc_dummy to update
6637 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
6638 first loc_chain location if NULL before. Always use just
6639 cur_loc instead of first loc_chain location. When cur_loc_changed
6640 is false, when not --enable-checking=rtl just don't emit any note.
6641 When rtl checking, compute the note and assert it is the same
6642 as previous note. Clear cur_loc_changed and in_changed_variables
6643 at the end before removing from changed_variables.
6644 (check_changed_vars_3): New function.
6645 (emit_notes_for_changes): Traverse changed_vars to call
