//===----------------------------------------------------------------------===// // 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/

This causes programs compiled with this flag to print a diagnostic when a control flow integrity check fails instead of aborting. Diagnostics are printed using UBSan's runtime library. The main motivation of this feature over -fsanitize=vptr is fidelity with the -fsanitize=cfi implementation: the diagnostics are printed under exactly the same conditions as those which would cause -fsanitize=cfi to abort the program. This means that the same restrictions apply regarding compiling all translation units with -fsanitize=cfi, cross-DSO virtual calls are forbidden, etc. Differential Revision: http://reviews.llvm.org/D10268 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@240109 91177308-0d34-0410-b5e6-96231b3b80d8
