From dc48412c938f39d51b8980db9f957cab30af671e Mon Sep 17 00:00:00 2001 From: Matthias Gehre Date: Mon, 12 Oct 2015 21:53:19 +0000 Subject: [clang-tidy] new check cppcoreguidelines-pro-bounds-pointer-arithmetic Summary: This check flags all usage of pointer arithmetic, because it could lead to an invalid pointer. Subtraction of two pointers is not flagged by this check. Pointers should only refer to single objects, and pointer arithmetic is fragile and easy to get wrong. array_view is a bounds-checked, safe type for accessing arrays of data. This rule is part of the "Bounds safety" profile of the C++ Core Guidelines, see https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds1-dont-use-pointer-arithmetic-use-array_view-instead Depends on D13313 Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D13311 llvm-svn: 250116 --- .../clang-tidy/cppcoreguidelines/CppCoreGuidelinesTidyModule.cpp | 3 +++ 1 file changed, 3 insertions(+) (limited to 'clang-tools-extra/clang-tidy/cppcoreguidelines/CppCoreGuidelinesTidyModule.cpp') diff --git a/clang-tools-extra/clang-tidy/cppcoreguidelines/CppCoreGuidelinesTidyModule.cpp b/clang-tools-extra/clang-tidy/cppcoreguidelines/CppCoreGuidelinesTidyModule.cpp index 358bd6ec8fd..07ba15a8b4a 100644 --- a/clang-tools-extra/clang-tidy/cppcoreguidelines/CppCoreGuidelinesTidyModule.cpp +++ b/clang-tools-extra/clang-tidy/cppcoreguidelines/CppCoreGuidelinesTidyModule.cpp @@ -10,6 +10,7 @@ #include "../ClangTidy.h" #include "../ClangTidyModule.h" #include "../ClangTidyModuleRegistry.h" +#include "ProBoundsPointerArithmeticCheck.h" #include "ProTypeConstCastCheck.h" #include "ProTypeReinterpretCastCheck.h" #include "ProTypeStaticCastDowncastCheck.h" @@ -22,6 +23,8 @@ namespace cppcoreguidelines { class CppCoreGuidelinesModule : public ClangTidyModule { public: void addCheckFactories(ClangTidyCheckFactories &CheckFactories) override { + CheckFactories.registerCheck( + "cppcoreguidelines-pro-bounds-pointer-arithmetic"); CheckFactories.registerCheck( "cppcoreguidelines-pro-type-const-cast"); CheckFactories.registerCheck( -- cgit v1.2.3
