All blacklisting logic is now moved to the frontend (Clang). If a function (or source file it is in) is blacklisted, it doesn't get sanitize_address attribute and is therefore not instrumented. If a global variable (or source file it is in) is blacklisted, it is reported to be blacklisted by the entry in llvm.asan.globals metadata, and is not modified by the instrumentation. The latter may lead to certain false positives - not all the globals created by Clang are described in llvm.asan.globals metadata (e.g, RTTI descriptors are not), so we may start reporting errors on them even if "module" they appear in is blacklisted. We assume it's fine to take such risk: 1) errors on these globals are rare and usually indicate wild memory access 2) we can lazily add descriptors for these globals into llvm.asan.globals lazily. llvm-svn: 212505 |

//===----------------------------------------------------------------------===// // 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.cs.uiuc.edu/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
