Currently adding attribute no_sanitize("bounds") isn't disabling -fsanitize=local-bounds (also enabled in -fsanitize=bounds). The Clang frontend handles fsanitize=array-bounds which can already be disabled by no_sanitize("bounds"). However, instrumentation added by the BoundsChecking pass in the middle-end cannot be disabled by the attribute. The fix is very similar to D102772 that added the ability to selectively disable sanitizer pass on certain functions. In this patch, if no_sanitize("bounds") is provided, an additional function attribute (NoSanitizeBounds) is attached to IR to let the BoundsChecking pass know we want to disable local-bounds checking. In order to support this feature, the IR is extended (similar to D102772) to make Clang able to preserve the information and let BoundsChecking pass know bounds checking is disabled for certain function.

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