From b212f3783a23a6c9fb18ffb450223e7117ab9c55 Mon Sep 17 00:00:00 2001 From: giovannibajo Date: Sun, 25 Jul 2004 22:52:22 +0000 Subject: PR c++/9283 PR c++/15000 * c-common.c (c_common_attribute_table): Allow handle_visibility_attribute to be called for types. (handle_visibility_attribute) When given a type, set the visibility bits on the TYPE_NAME. When given a decl, don't set no_add_attrs so that we can check later whether the attribute was present. Added warning if attribute applied to non class type. * c-decl.c (diagnose_mismatched_decls): Updated rules for merging decls and checking that they are consistent. * common.opt: Added -fvisibility. * c.opt, c-opts.c: Added -fvisibility-inlines-hidden. * c-pragma.h, c-pragma.c: Added handle_pragma_visibility(). * flags.h, tree.h: Added assorted support defines for overall patch * opts.c: Added parsing support for -fvisibility. * tree.c (build_decl): Set visibility for all decls to be whatever is in force at that time. * varasm.c (default_binds_local_p_1): Reworked logic determining when to make a symbol locally bound. * doc/invoke.texi: Added documentation for -fvisibility and -fvisibility-inlines-hidden. PR c++/15000 PR c++/9283 * class.c (check_field_decls): Apply hidden visibility if -fvisibility-inlines-hidden and inlined unless otherwise specified (build_vtable): Set vtable visibility to class visibility. (check_field_decls): Default static member visibility to class visibility. (check_methods): Default method visibility to class visibility. * cp-tree.h: Added CLASSTYPE_VISIBILITY and CLASSTYPE_VISIBILITY_SPECIFIED macro. * decl.c (duplicate_decls): New logic for merging definition decls with declaration decls. Added ignore & warning when non default applied to global operator new or delete. * method.c, optimize.c, rtti.c: Added setting of VISIBILITY_SPECIFIED wherever VISIBILITY was changed * rtti.c (get_tinfo_decl): Set typeinfo visibility to class visibility. (tinfo_base_init): Set typeinfo name visibility to class visibility.
