Sharing the FileManager across implicit module builds currently leaks paths looked up in an importer into the built module itself. This can cause non-deterministic results across scans. It is especially bad for modules since the path can be saved into the pcm file itself, leading to stateful behaviour if the cache is shared. This should not impact the number of real filesystem accesses in the scanner, since it is already caching in the DependencyScanningWorkerFilesystem. Note: this change does not affect whether or not the FileManager is shared across TUs in the scanner, which is a separate issue. Differential Revision: https://reviews.llvm.org/D131412 |

//===----------------------------------------------------------------------===// // 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 forums: https://discourse.llvm.org/c/clang/ If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
