+ * config/i386/i386.c (legitimate_constant_p): UNSPEC_TP is not
+ legitimate constant.
+ (legitimate_pic_operand_p): Neither pic operand.
+ (legitimate_address_p): But legitimate address.
+ (get_thread_pointer): Generate MEM/u instead of CONST around
+ UNSPEC_TP.
+ (print_operand): Remove printing of UNSPEC_TP.
+ (print_operand_address): And print it here.

* objc/objc-act.c (build_selector_translation_table): Issue warning,
when -Wselector is used,if method for which selector is being
created does not exist.
