Don Hinton 28413dd87a [clang-tidy] Add new checker: llvm-prefer-isa-or-dyn-cast-in-conditionals Summary: Looks at conditionals and finds cases of ``cast<>``, which will assert rather than return a null pointer, and ``dyn_cast<>`` where the return value is not captured. Additionally, finds cases that match the pattern ``var.foo() && isa<X>(var.foo())``, where the method is called twice and could be expensive. .. code-block:: c++ // Finds cases like these: if (auto x = cast<X>(y)) <...> if (cast<X>(y)) <...> // But not cases like these: if (auto f = cast<Z>(y)->foo()) <...> if (cast<Z>(y)->foo()) <...> Reviewers: alexfh, rjmccall, hokein, aaron.ballman, JonasToth Reviewed By: aaron.ballman Subscribers: xbolva00, Eugene.Zelenko, mgorny, xazax.hun, cfe-commits Tags: #clang-tools-extra, #clang Differential Revision: https://reviews.llvm.org/D59802 llvm-svn: 359142		2019-04-24 21:25:57 +00:00

// Clang Tools repository
//===----------------------------------------------------------------------===//

Welcome to the repository of extra Clang Tools.  This repository holds tools
that are developed as part of the LLVM compiler infrastructure project and the
Clang frontend.  These tools are kept in a separate "extra" repository to
allow lighter weight checkouts of the core Clang codebase.

This repository is only intended to be checked out inside of a full LLVM+Clang
tree, and in the 'tools/extra' subdirectory of the Clang checkout.

All discussion regarding Clang, Clang-based tools, and code in this repository
should be held using the standard Clang mailing lists:
  http://lists.llvm.org/mailman/listinfo/cfe-dev

Code review for this tree should take place on the standard Clang patch and
commit lists:
  http://lists.llvm.org/mailman/listinfo/cfe-commits

If you find a bug in these tools, please file it in the LLVM bug tracker:
  http://llvm.org/bugs/
