Summary: We're using the clang static analyzer together with a number of custom analyses in our CI system to ensure that certain invariants are statiesfied for by the code every commit. Unfortunately, there currently doesn't seem to be a good way to determine whether any analyzer warnings were emitted, other than parsing clang's output (or using scan-build, which then in turn parses clang's output). As a simpler mechanism, simply add a `-analyzer-werror` flag to CC1 that causes the analyzer to emit its warnings as errors instead. I briefly tried to have this be `Werror=analyzer` and make it go through that machinery instead, but that seemed more trouble than it was worth in terms of conflicting with options to the actual build and special cases that would be required to circumvent the analyzers usual attempts to quiet non-analyzer warnings. This is simple and it works well. Reviewed-By: NoQ, Szelethusw Differential Revision: https://reviews.llvm.org/D62885 llvm-svn: 362855 |

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
