(java_push_parser_context): Remember ctxp->gclass_list across contexts. (java_pop_parser_context): Simply return if no context exists. Remember gclass_list across contexts. (issue_warning_error_from_context): New function. (parse_error_context): Don't setup ctxp->elc here. Call issue_warning_error_from_context instead. (parse_warning_context): Likewise. (maybe_create_class_interface_decl): Removed DECL_ARTIFICIAL setup. Link new class/interface to ctxp->gclass_list. (add_superinterfaces): Register interface as incomplete if not loaded. (create_class): Remember class unqualified name in ctxp->current_parsed_class_un. Check class deprecation. (register_fields): Check field deprecation. Remember static final field value in DECL_LOCAL_STATIC_VALUE. Changed comment in part processing INIT. (method_header): New local variable ORIG_ARG. Use unqualified current class name for check on constructor errors. Promote return type if of record type. Argument list fix moved in fix_method_argument_names, called here. Check method deprecation. (fix_method_argument_names): New function. (method_declarator): Promote record typed arguments. (safe_layout_class): Check class methods before layout. (java_complete_class): Compute field layout when patched. (do_resolve_class): Try to load class after having it renamed after the package name. (get_printable_method_name): Use DECL_CONTEXT. (reset_method_name): New function. (check_method_redefinition): Use reset_method_name. (java_check_regular_methods): New local variable SAVED_FOUND_WFL. Temporarily reinstall overriding/hiding method names for error report. Check for compile-time error when method found has default (package) access. (java_check_abstract_methods): Now takes an interface DECL node as an argument. Also reinstall real name on unchecked overriding/hiding methods for error report. (java_check_methods): Fixed leading comment. Get classes to verify from ctxp->gclass_list. Use CHECK_METHODS macro and set CLASS_METHOD_CHECKED_P on class verification. (lookup_java_method2): Get real method name if necessary. (find_in_imports): Don't check package class access here. (resolve_package, lookup_package_type): New functions. (java_layout_classes): Fixed leading comment. Take classes to be laid out from ctxp->gclass_list. (java_complete_expand_methods): Don't expand native and abstract methods. (java_expand_classes): New function. (resolve_expression_name): Use additional argument ORIG. Retrieve values of static final field of primitive types. (resolve_field_access): Handles static final field of promotive type. (resolve_qualified_expression_name): Handle STRING_CST as primaries and package name resolution. Check deprecation on found decls. Set where_found and type_found on non static field resolved during qualification. Layout non primitive field decl types. (check_deprecation): New function. (maybe_access_field): Simplified. (patch_method_invocation_stmt): Local variable CLASS_TYPE removed. Reverse method's argument when primary is a type. Don't use CLASS_TYPE to report problems, use IDENTIFIER_WFL instead. Include abstract class in the list of class searchable for constructors. Use DECL_CONTEXT of found method for access checks. Check method deprecation. (patch_invoke): Pay extra care to NEW_CLASS_EXPR type call when converting arguments. Handle INVOKE_INTERFACE. (lookup_method_invoke): Search constructor using existing infrastructure (don't rely on lookup_java_constructor anymore). (find_applicable_accessible_methods_list): Extra argument flag LC. Now include constructor in the search. (qualify_ambiguous_name): Conditional expression are primaries. (not_initialized_as_it_should_p): static final are always initialized. (java_complete_tree): Pass extra NULL argument to resolve_expression_name. Stricter test to carry on patching assignments. New case for INSTANCEOF_EXPR. (complete_function_arguments): Inline PRIMTYPE.TYPE read access. (check_final_assignment, maybe_build_primttype_type_ref): New functions. (patch_assignment): Detect resolved static finals and carry normal assignment error check on them. Inline PRIMTYPE.TYPE read access. (try_builtin_assignconv): Access constant 0 on all primitive types. (valid_builtin_assignconv_identity_widening_p): Accept identical types. Accept all promoted type on int type. (valid_ref_assignconv_cast_p): Accept a null pointer to be assigned to a reference. (valid_method_invocation_conversion_p): Accept to check null pointers. (build_binop): Merge declaration and initialization of local variable BINOP. (patch_binop): New case for INSTANCEOF_EXPR. NE_EXPR to accept all numeric types. Improved validity test for qualify operators on references. (patch_unaryop): Broadened rejection test for PREDECREMENT_EXPR and PREINCREMENT_EXPR. Also detect resolved static finals of a primitive type and issue the appropriate error message. (resolve_type_during_patch): Mark class loaded when resolved. (patch_cast): Allow null to be cased to reference types. (build_null_of_type): New function. (patch_array_ref): Handle array on references correctly. (patch_return): Removed unused local variable MODIFY. Force boolean to be returned as integers. Allows null to be returned by a function returning a reference. * typeck.c (convert_to_integer, convert_to_real, convert_to_pointer): Prototypes moved to convert.h (lookup_argument_method): Use method real name, if necessary. This improves method checking, gets rid of a cross file type dependency bug and does a more robust job at laying out classes when necessary. It unifies the regular methods and constructors lookup. It implements the `instanceof' operator and interface method invocations. It also fixes random bugs. From-SVN: r23599
