Artem Dergachev 4579bad86c [analyzer] Add a checker for mmap()s which are both writable and executable.
This is a security check that warns when both PROT_WRITE and PROT_EXEC are
set during mmap(). If mmap()ed memory is both writable and executable, it makes
it easier for the attacker to execute arbitrary code when contents of this
memory are compromised. Some applications require such mmap()s though, such as
different sorts of JIT.

Re-applied after a revert in r324167.

Temporarily stays in the alpha package because it needs a better way of
determining macro values that are not immediately available in the AST.

Patch by David Carlier!

// 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
