* [clang-tidy] cppcoreguidelines-pro-bounds-pointer-arithmetic: ignore ↵Matthias Gehre2015-11-261-5/+9
| | | | | | | | | | | | | | | | generated pointer arithmetic Summary: Inside a range-based for-loop over an array, the compiler generates pointer arithmetic (end = array + size). Don't flag this.

* [clang-tidy] new check cppcoreguidelines-pro-bounds-pointer-arithmeticMatthias Gehre2015-10-121-0/+53
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
