From 9e5b21156632fd14bfaeea24919c614e56645989 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Sat, 13 Nov 2010 09:52:00 +0000 Subject: c-tree.h (enum c_typespec_kind): Add ctsk_none. 2010-11-13 Paolo Bonzini * c-tree.h (enum c_typespec_kind): Add ctsk_none. (struct c_declspecs): Replace tagdef_seen_p and type_seen_p with typespec_kind. * c-decl.c (build_null_declspecs): Initialize typespec_kind. (shadow_tag_warned, check_compound_literal_type): Adjust uses of tag_defined_p. (declspecs_add_type): Set typespec_kind. * c-parser.c (c_parser_declaration_or_fndef, c_parser_declspecs, c_parser_struct_declaration, c_parser_parameter_declaration, c_parser_type_name, c_parser_objc_diagnose_bad_element_prefix): Adjust uses of type_seen_p. * c-typeck.c (c_cast_expr): Use typespec_kind instead of tag_defined_p, pass ctsk_firstref through. testsuite: 2010-11-13 Paolo Bonzini * gcc.dg/Wcxx-compat-8.c: Add testcases involving incomplete types.
