<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Vlad Serebrennikov (Endilll) <details> <summary>Changes</summary> This patch adds `CXXPre26Compat` and `CXXPre26CompatPedantic` groups (which are concerned with new features not available in older language modes) to `CXX98Compat`, etc. This way, if user has `-Wc++20-compat` and they use pack indexing, they will be warned. Ideally this should have been done when C++26 groups were created, but we shipped two releases of Clang since then. --- Full diff: https://github.com/llvm/llvm-project/pull/97806.diff 2 Files Affected: - (modified) clang/docs/ReleaseNotes.rst (+4) - (modified) clang/include/clang/Basic/DiagnosticGroups.td (+20-10) ``````````diff diff --git a/clang/docs/ReleaseNotes.rst b/clang/docs/ReleaseNotes.rst index 36cf615a4287c..cf1b529eb7321 100644 --- a/clang/docs/ReleaseNotes.rst +++ b/clang/docs/ReleaseNotes.rst @@ -476,6 +476,10 @@ Modified Compiler Flags evaluating to ``true`` and an empty body such as ``while(1);``) are considered infinite, even when the ``-ffinite-loop`` flag is set. +- Diagnostics groups about compatibility with a particular C++ Standard version + now include dianostics about C++26 features that are not present in older + versions. + Removed Compiler Flags ------------------------- diff --git a/clang/include/clang/Basic/DiagnosticGroups.td b/clang/include/clang/Basic/DiagnosticGroups.td index 9431eea1f6be2..a4496431e46e4 100644 --- a/clang/include/clang/Basic/DiagnosticGroups.td +++ b/clang/include/clang/Basic/DiagnosticGroups.td @@ -344,7 +344,8 @@ def CXX98Compat : DiagGroup<"c++98-compat", CXXPre14Compat, CXXPre17Compat, CXXPre20Compat, - CXXPre23Compat]>; + CXXPre23Compat, + CXXPre26Compat]>; // Warnings for C++11 features which are Extensions in C++98 mode. def CXX98CompatPedantic : DiagGroup<"c++98-compat-pedantic", [CXX98Compat, @@ -353,7 +354,8 @@ def CXX98CompatPedantic : DiagGroup<"c++98-compat-pedantic", CXXPre14CompatPedantic, CXXPre17CompatPedantic, CXXPre20CompatPedantic, - CXXPre23CompatPedantic]>; + CXXPre23CompatPedantic, + CXXPre26CompatPedantic]>; def CXX11NarrowingConstReference : DiagGroup<"c++11-narrowing-const-reference">; def CXX11Narrowing : DiagGroup<"c++11-narrowing", [CXX11NarrowingConstReference]>; @@ -384,39 +386,47 @@ def CXX11Compat : DiagGroup<"c++11-compat", CXXPre14Compat, CXXPre17Compat, CXXPre20Compat, - CXXPre23Compat]>; + CXXPre23Compat, + CXXPre26Compat]>; def : DiagGroup<"c++0x-compat", [CXX11Compat]>; def CXX11CompatPedantic : DiagGroup<"c++11-compat-pedantic", [CXX11Compat, CXXPre14CompatPedantic, CXXPre17CompatPedantic, CXXPre20CompatPedantic, - CXXPre23CompatPedantic]>; + CXXPre23CompatPedantic, + CXXPre26CompatPedantic]>; def CXX14Compat : DiagGroup<"c++14-compat", [CXXPre17Compat, CXXPre20Compat, - CXXPre23Compat]>; + CXXPre23Compat, + CXXPre26Compat]>; def CXX14CompatPedantic : DiagGroup<"c++14-compat-pedantic", [CXX14Compat, CXXPre17CompatPedantic, CXXPre20CompatPedantic, - CXXPre23CompatPedantic]>; + CXXPre23CompatPedantic, + CXXPre26CompatPedantic]>; def CXX17Compat : DiagGroup<"c++17-compat", [DeprecatedRegister, DeprecatedIncrementBool, CXX17CompatMangling, CXXPre20Compat, - CXXPre23Compat]>; + CXXPre23Compat, + CXXPre26Compat]>; def CXX17CompatPedantic : DiagGroup<"c++17-compat-pedantic", [CXX17Compat, CXXPre20CompatPedantic, - CXXPre23CompatPedantic]>; + CXXPre23CompatPedantic, + CXXPre26CompatPedantic]>; def : DiagGroup<"c++1z-compat", [CXX17Compat]>; -def CXX20Compat : DiagGroup<"c++20-compat", [CXXPre23Compat]>; +def CXX20Compat : DiagGroup<"c++20-compat", [CXXPre23Compat, + CXXPre26Compat]>; def CXX20CompatPedantic : DiagGroup<"c++20-compat-pedantic", [CXX20Compat, - CXXPre23CompatPedantic]>; + CXXPre23CompatPedantic, + CXXPre26CompatPedantic]>; def : DiagGroup<"c++2a-compat", [CXX20Compat]>; def : DiagGroup<"c++2a-compat-pedantic", [CXX20CompatPedantic]>; `````````` </details> https://github.com/llvm/llvm-project/pull/97806 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
