<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: None (Sirraide) <details> <summary>Changes</summary> Following the discussion on [#<!-- -->101448](https://github.com/llvm/llvm-project/pull/101448#pullrequestreview-2217511926), this defines `__cpp_pack_indexing`. Since pack indexing is currently supported in all language modes, the feature test macro is also defined in all language modes. --- Full diff: https://github.com/llvm/llvm-project/pull/101956.diff 3 Files Affected: - (modified) clang/docs/LanguageExtensions.rst (+1) - (modified) clang/lib/Frontend/InitPreprocessor.cpp (+1) - (modified) clang/test/Lexer/cxx-features.cpp (+4) ``````````diff diff --git a/clang/docs/LanguageExtensions.rst b/clang/docs/LanguageExtensions.rst index 9dcb4ac9b75ca..be07f81cc41b0 100644 --- a/clang/docs/LanguageExtensions.rst +++ b/clang/docs/LanguageExtensions.rst @@ -1503,6 +1503,7 @@ Conditional ``explicit`` __cpp_conditional_explicit C+ ``static operator()`` __cpp_static_call_operator C++23 C++03 Attributes on Lambda-Expressions C++23 C++11 Attributes on Structured Bindings __cpp_structured_bindings C++26 C++03 +Pack Indexing __cpp_pack_indexing C++26 C++03 ``= delete ("should have a reason");`` __cpp_deleted_function C++26 C++03 -------------------------------------------- -------------------------------- ------------- ------------- Designated initializers (N494) C99 C89 diff --git a/clang/lib/Frontend/InitPreprocessor.cpp b/clang/lib/Frontend/InitPreprocessor.cpp index 17b9ca7cb9910..8e62461d8a181 100644 --- a/clang/lib/Frontend/InitPreprocessor.cpp +++ b/clang/lib/Frontend/InitPreprocessor.cpp @@ -763,6 +763,7 @@ static void InitializeCPlusPlusFeatureTestMacros(const LangOptions &LangOpts, Builder.defineMacro("__cpp_placeholder_variables", "202306L"); // C++26 features supported in earlier language modes. + Builder.defineMacro("__cpp_pack_indexing", "202311L"); Builder.defineMacro("__cpp_deleted_function", "202403L"); if (LangOpts.Char8) diff --git a/clang/test/Lexer/cxx-features.cpp b/clang/test/Lexer/cxx-features.cpp index 4c2aa3ae2c544..08b732132228b 100644 --- a/clang/test/Lexer/cxx-features.cpp +++ b/clang/test/Lexer/cxx-features.cpp @@ -38,6 +38,10 @@ #error "wrong value for __cpp_deleted_function" #endif +#if check(pack_indexing, 202311, 202311, 202311, 202311, 202311, 202311, 202311) +#error "wrong value for __cpp_pack_indexing" +#endif + #if check(placeholder_variables, 202306, 202306, 202306, 202306, 202306, 202306, 202306) #error "wrong value for __cpp_placeholder_variables" #endif `````````` </details> https://github.com/llvm/llvm-project/pull/101956 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
