From b04445d4a809eaf0460fd4f1f35b1a7d458c8c72 Mon Sep 17 00:00:00 2001 From: Jason Merrill Date: Wed, 13 May 2020 15:15:13 -0400 Subject: c++: Replace "C++2a" with "C++20". C++20 isn't final quite yet, but all that remains is formalities, so let's go ahead and change all the references. I think for the next C++ standard we can just call it C++23 rather than C++2b, since the committee has been consistent about time-based releases rather than feature-based. gcc/c-family/ChangeLog 2020-05-13 Jason Merrill * c.opt (std=c++20): Make c++2a the alias. (std=gnu++20): Likewise. * c-common.h (cxx_dialect): Change cxx2a to cxx20. * c-opts.c: Adjust. * c-cppbuiltin.c: Adjust. * c-ubsan.c: Adjust. * c-warn.c: Adjust. gcc/cp/ChangeLog 2020-05-13 Jason Merrill * call.c, class.c, constexpr.c, constraint.cc, decl.c, init.c, lambda.c, lex.c, method.c, name-lookup.c, parser.c, pt.c, tree.c, typeck2.c: Change cxx2a to cxx20. libcpp/ChangeLog 2020-05-13 Jason Merrill * include/cpplib.h (enum c_lang): Change CXX2A to CXX20. * init.c, lex.c: Adjust. --- libcpp/macro.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'libcpp/macro.c') diff --git a/libcpp/macro.c b/libcpp/macro.c index 2573f31..dc4366f 100644 --- a/libcpp/macro.c +++ b/libcpp/macro.c @@ -1035,7 +1035,7 @@ _cpp_arguments_ok (cpp_reader *pfile, cpp_macro *macro, const cpp_hashnode *node if (argc < macro->paramc) { - /* In C++2a (here the va_opt flag is used), and also as a GNU + /* In C++20 (here the va_opt flag is used), and also as a GNU extension, variadic arguments are allowed to not appear in the invocation at all. e.g. #define debug(format, args...) something -- cgit v1.1
