Summary: This check flags all array subscriptions on static arrays and std::arrays that either have a non-compile-time-constant index or are out of bounds. Dynamic accesses into arrays are difficult for both tools and humans to validate as safe. array_view is a bounds-checked, safe type for accessing arrays of data. at() is another alternative that ensures single accesses are bounds-checked. If iterators are needed to access an array, use the iterators from an array_view constructed over the array. This rule is part of the "Bounds safety" profile of the C++ Core Guidelines, see https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds2-only-index-into-arrays-using-constant-expressions Reviewers: alexfh, sbenza, bkramer, aaron.ballman Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D13746 llvm-svn: 253401
