Description: Clang is an LLVM native C/C++/Objective-C compiler, which
aims to deliver amazingly fast compiles (e.g. about 3x
faster than GCC when compiling Objective-C code in a
debug configuration), extremely useful error and warning
messages and to provide a platform for building great
source level tools. The included Clang Static Analyzer is
a tool automatically finds bugs in your code, and is a
great example of the sort of tool that can be built using
the Clang frontend as a library to parse C/C++ code.
