* [clang-tidy] fix PR36489 - respect deduced pointer types from auto as wellJonas Toth2018-07-231-2/+6
| | | | | | | | | | | | | | | | | | | | Summary: The cppcoreguidelines-pro-bounds-pointer-arithmetic warns on all occassion where pointer arithmetic is used, but does not check values where the pointer types is deduced via `auto`. This patch adjusts this behaviour and solved PR36489. I accidentally commited a wrong patch, this Differential is meant to have a correct revision description and code attached to it. Because the patch was accepted by aaron.ballman already, i will just commit it.

* [clang-tools-extra] Format sources with clang-format. NFC.Mandeep Singh Grang2016-11-081-2/+2
| | | | | | | | | | | | | | | | Summary: Ran clang-format on all .c/.cpp/.h files in clang-tools-extra. Excluded the test, unittests, clang-reorder-fields, include-fixer, modularize and pptrace directories.

* [clang-tidy] Cleaning namespaces to be more consistant across checkers.Etienne Bergeron2016-05-021-0/+2
| | | | | | | | | | | | | | Summary: The goal of the patch is to bring checkers in their appropriate namespace. This path doesn't change any behavior. Reviewers: alexfh Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D19811 llvm-svn: 268264

| | | | | | | | | | | | | | | | 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
