* [clang-tidy] Add bugprone-suspicious-memset-usage checkGabor Horvath2017-07-141-39/+0
| | | | | | | | | | | | | | | | | | Created new module bugprone and placed the check in that. Finds memset() calls with potential mistakes in their arguments. Replaces and extends the existing google-runtime-memset-zero-length check. Cases covered: * Fill value is a character '0'. Integer 0 might have been intended. * Fill value is out of char range and gets truncated. * Byte count is zero. Potentially swapped with the fill value argument.

* [clang-tidy] Update docs for clang-tidy checks. NFCAlexander Kornienko2015-08-271-1/+1
| | | | | | | | | | | Changes mostly address formatting and unification of the style. Use MarkDown style for inline code snippets and lists. Added some text for a few checks. The idea is to move most of the documentation out to separate rST files and have implementation files refer to the corresponding documentation files. llvm-svn: 246169
* [clang-tidy] Fixed header guards using clang-tidy llvm-header-guard check. NFC.Alexander Kornienko2015-03-091-3/+3

* Implemented clang-tidy-check-specific options.Alexander Kornienko2014-09-121-0/+2
| | | | | | | | | | | | | | | | | Summary: Each check can implement readOptions and storeOptions methods to read and store custom options. Each check's options are stored in a local namespace to avoid name collisions and provide some sort of context to the user.

* [clang-tidy] Add a checker for zero-length memset.Benjamin Kramer2014-07-161-0/+35
If there's memset(x, y, 0) in the code it's most likely a mistake. The checker suggests a fix-it to swap 'y' and '0'. I think this has the potential to be promoted into a general clang warning after some testing in clang-tidy. Differential Revision: http://reviews.llvm.org/D4535 llvm-svn: 213155
