45  *
46  * This modules provide an interface to libLLVMCore, which implements
47  * the LLVM intermediate representation as well as other related types
48  * and utilities.
49  *
50  * LLVM uses a polymorphic type hierarchy which C cannot represent, therefore
51  * parameters must be passed as base types. Despite the declared types, most
52  * of the functions provided operate only on branches of the type hierarchy.
53  * The declared parameter names are descriptive and specify which type is
54  * required. Additionally, each type hierarchy is documented along with the
55  * functions that operate upon it. For more detail, refer to LLVM's C++ code.
56  * If in doubt, refer to Core.cpp, which performs parameter downcasts in the
57  * form unwrap<RequiredType>(Param).
58  *
59  * Many exotic languages can interoperate with C code but have a harder time
60  * with C++ due to name mangling. So in addition to C, this interface enables
61  * tools written in such languages.
62  *
63  * When included into a C++ source file, also declares 'wrap' and 'unwrap'
64  * helpers to perform opaque reference<-->pointer conversions. These helpers
65  * are shorter and more tightly typed than writing the casts by hand when
66  * authoring bindings. In assert builds, they will do runtime type checking.
