+ * frame.c (get_current_frame): Check target_has_registers before
+ checking target_has_stack.
+ * eval.c (evaluate_subexp_standard): Use get_selected_frame,
+ instead of deprecated_selected_frame.
+ * findvar.c (value_of_register): Pass "frame", not
+ deprecated_selected_frame, to value_of_builtin_reg.

* regcache.c (regcache_cooked_write_signed): New function.
