#ifndef RUBY_BACKWARD2_ATTRIBUTES_H /*-*-C++-*-vi:se ft=cpp:*/ #define RUBY_BACKWARD2_ATTRIBUTES_H /** * @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 Various attribute-related macros. * * ### Q&A ### * * - Q: Why are the macros defined in this header file so inconsistent in * style? * * - A: Don't know. Don't blame me. Backward compatibility is the key here. * I'm just preserving what they have been. */ #include "ruby/internal/config.h" #include "ruby/internal/attr/alloc_size.h" #include "ruby/internal/attr/cold.h" #include "ruby/internal/attr/const.h" #include "ruby/internal/attr/deprecated.h" #include "ruby/internal/attr/error.h" #include "ruby/internal/attr/forceinline.h" #include "ruby/internal/attr/format.h" #include "ruby/internal/attr/maybe_unused.h" #include "ruby/internal/attr/noinline.h" #include "ruby/internal/attr/nonnull.h" #include "ruby/internal/attr/noreturn.h" #include "ruby/internal/attr/packed_struct.h" #include "ruby/internal/attr/pure.h" #include "ruby/internal/attr/restrict.h" #include "ruby/internal/attr/returns_nonnull.h" #include "ruby/internal/attr/warning.h" #include "ruby/internal/has/attribute.h" /* function attributes */ #undef CONSTFUNC #define CONSTFUNC(x) RBIMPL_ATTR_CONST() x #undef PUREFUNC #define PUREFUNC(x) RBIMPL_ATTR_PURE() x #undef DEPRECATED #define DEPRECATED(x) RBIMPL_ATTR_DEPRECATED(("")) x #undef DEPRECATED_BY #define DEPRECATED_BY(n,x) RBIMPL_ATTR_DEPRECATED(("by: " # n)) x #undef DEPRECATED_TYPE #if defined(__GNUC__) # define DEPRECATED_TYPE(mesg, decl) \ _Pragma("message \"DEPRECATED_TYPE is deprecated\""); \ decl RBIMPL_ATTR_DEPRECATED(mseg) #elif defined(_MSC_VER) # pragma deprecated(DEPRECATED_TYPE) # define DEPRECATED_TYPE(mesg, decl) \ __pragma(message(__FILE__"("STRINGIZE(__LINE__)"): warning: " \ "DEPRECATED_TYPE is deprecated")) \ decl RBIMPL_ATTR_DEPRECATED(mseg) #else # define DEPRECATED_TYPE(mesg, decl) \ <-<-"DEPRECATED_TYPE is deprecated"->-> #endif #undef RUBY_CXX_DEPRECATED #define RUBY_CXX_DEPRECATED(mseg) RBIMPL_ATTR_DEPRECATED((mseg)) #undef NOINLINE #define NOINLINE(x) RBIMPL_ATTR_NOINLINE() x #undef ALWAYS_INLINE #define ALWAYS_INLINE(x) RBIMPL_ATTR_FORCEINLINE() x #undef ERRORFUNC #define ERRORFUNC(mesg, x) RBIMPL_ATTR_ERROR(mesg) x #if RBIMPL_HAS_ATTRIBUTE(error) # define HAVE_ATTRIBUTE_ERRORFUNC 1 #endif #undef WARNINGFUNC #define WARNINGFUNC(mesg, x) RBIMPL_ATTR_WARNING(mesg) x #if RBIMPL_HAS_ATTRIBUTE(warning) # define HAVE_ATTRIBUTE_WARNINGFUNC 1 #endif /* cold attribute for code layout improvements RUBY_FUNC_ATTRIBUTE not used because MSVC does not like nested func macros */ #undef COLDFUNC #define COLDFUNC RBIMPL_ATTR_COLD() #define PRINTF_ARGS(decl, string_index, first_to_check) \ RBIMPL_ATTR_FORMAT(RBIMPL_PRINTF_FORMAT, (string_index), (first_to_check)) \ decl #undef RUBY_ATTR_ALLOC_SIZE #define RUBY_ATTR_ALLOC_SIZE RBIMPL_ATTR_ALLOC_SIZE #undef RUBY_ATTR_MALLOC #define RUBY_ATTR_MALLOC RBIMPL_ATTR_RESTRICT() #undef RUBY_ATTR_RETURNS_NONNULL #define RUBY_ATTR_RETURNS_NONNULL RBIMPL_ATTR_RETURNS_NONNULL() #ifndef FUNC_MINIMIZED #define FUNC_MINIMIZED(x) x #endif #ifndef FUNC_UNOPTIMIZED #define FUNC_UNOPTIMIZED(x) x #endif #ifndef RUBY_ALIAS_FUNCTION_TYPE #define RUBY_ALIAS_FUNCTION_TYPE(type, prot, name, args) \ FUNC_MINIMIZED(type prot) {return (type)name args;} #endif #ifndef RUBY_ALIAS_FUNCTION_VOID #define RUBY_ALIAS_FUNCTION_VOID(prot, name, args) \ FUNC_MINIMIZED(void prot) {name args;} #endif #ifndef RUBY_ALIAS_FUNCTION #define RUBY_ALIAS_FUNCTION(prot, name, args) \ RUBY_ALIAS_FUNCTION_TYPE(VALUE, prot, name, args) #endif #undef RUBY_FUNC_NONNULL #define RUBY_FUNC_NONNULL(n, x) RBIMPL_ATTR_NONNULL(n) x #undef NORETURN #define NORETURN(x) RBIMPL_ATTR_NORETURN() x #define NORETURN_STYLE_NEW #undef PACKED_STRUCT #define PACKED_STRUCT(x) \ RBIMPL_ATTR_PACKED_STRUCT_BEGIN() x RBIMPL_ATTR_PACKED_STRUCT_END() #undef PACKED_STRUCT_UNALIGNED #define PACKED_STRUCT_UNALIGNED(x) \ RBIMPL_ATTR_PACKED_STRUCT_UNALIGNED_BEGIN() x \ RBIMPL_ATTR_PACKED_STRUCT_UNALIGNED_END() #undef RB_UNUSED_VAR #define RB_UNUSED_VAR(x) x RBIMPL_ATTR_MAYBE_UNUSED() #endif /* RUBY_BACKWARD2_ATTRIBUTES_H */
