Artem Dergachev cbd7cd8360 [analyzer] Improve subscripting null arrays for catching null dereferences.
Array-to-pointer cast now works correctly when the pointer to the array
is concrete, eg. null, which allows further symbolic calculations involving
such values.

Inlined defensive checks are now detected correctly when the resulting null
symbol is being array-subscripted before dereference.

// 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:

If you have questions or comments about Clang, a great place to discuss them is
