Check applied to unbounded (incomplete) arrays and pointers to spot cases where the computed address is beyond the largest possible addressable extent of the array, based on the address space in which the array is delcared, or which the pointer refers to. Check helps to avoid cases of nonsense pointer math and array indexing which could lead to linker failures or runtime exceptions. Of particular interest when building for embedded systems with small address spaces. This is version 2 of this patch -- version 1 had some testing issues due to a sign error in existing code. That error is corrected and lit test for this chagne is extended to verify the fix.

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