7084 already, reset in_changed_variables flag for it and propagate
7085 cur_loc_changed over to the new variable. On empty var
7086 always set cur_loc_changed. Set in_changed_variables on whatever
7087 var is added to changed_variables.
7088 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
7089 Use shared_var_p. When removing loc that is equal to cur_loc,
7090 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
7091 end, don't set it to something else, just call variable_was_changed.
7092 (delete_slot_part): Use shared_var_p. When cur_loc equals to
7093 loc being removed, clear cur_loc and set cur_loc_changed.

7095 (struct expand_loc_callback_data): New type.
7096 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
7097 allocated. Always create SUBREGs if simplify_subreg failed.
7098 Prefer to use cur_loc, when that fails and still in

7100 cur_loc_changed of variables which had to change cur_loc and
7101 compute elcd->cur_loc_changed if any of the subexpressions used
7102 had to change cur_loc.
7103 (vt_expand_loc): Adjust to pass arguments in
7104 expand_loc_callback_data structure.
7105 (vt_expand_loc_dummy): New function.
7106 (emitted_notes): New variable.
7107 (emit_note_insn_var_location): For VALUEs and DEBUG_EXPR_DECLs
7108 that weren't used for any other decl in current
7109 emit_notes_for_changes call call vt_expand_loc_dummy to update
7110 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
7111 first loc_chain location if NULL before. Always use just
7112 cur_loc instead of first loc_chain location. When cur_loc_changed
7113 is false, when not --enable-checking=rtl just don't emit any note.
7114 When rtl checking, compute the note and assert it is the same
7115 as previous note. Clear cur_loc_changed and in_changed_variables
7116 at the end before removing from changed_variables.
7117 (check_changed_vars_3): New function.
7118 (emit_notes_for_changes): Traverse changed_vars to call
