#ifndef RBIMPL_ANYARGS_H /*-*-C++-*-vi:se ft=cpp:*/ #define RBIMPL_ANYARGS_H /** * @file * @author Ruby developers <ruby-core@ruby-lang.org> * @copyright This file is a part of the programming language Ruby. * Permission is hereby granted, to either redistribute and/or * modify this file, provided that the conditions mentioned in the * file COPYING are met. Consult the file for details. * @warning Symbols prefixed with either `RBIMPL` or `rbimpl` are * implementation details. Don't take them as canon. They could * rapidly appear then vanish. The name (path) of this header file * is also an implementation detail. Do not expect it to persist * at the place it is now. Developers are free to move it anywhere * anytime at will. * @note To ruby-core: remember that this header can be possibly * recursively included from extension libraries written in C++. * Do not expect for instance `__VA_ARGS__` is always available. * We assume C99 for ruby itself but we don't assume languages of * extension libraries. They could be written in C++98. * @brief Function overloads to issue warnings around #ANYARGS. * * For instance ::rb_define_method takes a pointer to #ANYARGS -ed functions, * which in fact varies 18 different prototypes. We still need to preserve * #ANYARGS for storages but why not check the consistencies if possible. With * those complex macro overlays defined in this header file, use of a function * pointer gets checked against the corresponding arity argument. * * ### Q&A ### * * - Q: Where did the magic number "18" came from in the description above? * * - A: Count the case branch of `vm_method.c:call_cfunc_invoker_func()`. Note * also that the 18 branches has lasted for at least 25 years. See also * commit 200e0ee2fd3c1c006c528874a88f684447215524. * * - Q: What is this `__weakref__` thing? * * - A: That is a kind of function overloading mechanism that GCC provides. In * this case for instance `rb_define_method_00` is an alias of * ::rb_define_method, with a strong type. * * - Q: What is this `__transparent_union__` thing? * * A: That is another kind of function overloading mechanism that GCC * provides. In this case the attributed function pointer is either * `VALUE(*)(int,VALUE*,VALUE)` or `VALUE(*)(int,const VALUE*,VALUE)`. * * This is better than `void*` or #ANYARGS because we can reject all other * possibilities than the two. * * - Q: What does this #rb_define_method macro mean? * * - A: It selects appropriate alias of the ::rb_define_method function, * depending on the last (arity) argument. * * - Q: Why the special case for ::rb_f_notimplement ? * * - A: Function pointer to ::rb_f_notimplement is special cased in * `vm_method.c:rb_add_method_cfunc()`. That should be handled by the * `__builtin_choose_expr` chain inside of #rb_define_method macro * expansion. In order to do so, comparison like * `(func == rb_f_notimplement)` is inappropriate for * `__builtin_choose_expr`'s expression (which must be a compile-time * integer constant but the address of ::rb_f_notimplement is not fixed * until the linker). Instead we are using * `__builtin_types_compatible_p`, and in doing so we need to distinguish * ::rb_f_notimplement from others, by type. */ #include "ruby/internal/attr/maybe_unused.h" #include "ruby/internal/attr/nonnull.h" #include "ruby/internal/attr/weakref.h" #include "ruby/internal/cast.h" #include "ruby/internal/config.h" #include "ruby/internal/has/attribute.h" #include "ruby/internal/intern/class.h" #include "ruby/internal/intern/vm.h" #include "ruby/internal/method.h" #include "ruby/internal/value.h" #include "ruby/backward/2/stdarg.h" #if defined(__cplusplus) # include "ruby/backward/cxxanyargs.hpp" #elif defined(_WIN32) || defined(__CYGWIN__) # /* Skip due to [Bug #16134] */ # define RBIMPL_CAST_FN_PTR 1 #elif !
