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