     10 |* This header declares the C interface to libLLVMCore.a, which implements    *|
     11 |* the LLVM intermediate representation.                                      *|
     12 |*                                                                            *|
     13 |* LLVM uses a polymorphic type hierarchy which C cannot represent, therefore *|
     14 |* parameters must be passed as base types. Despite the declared types, most  *|
     15 |* of the functions provided operate only on branches of the type hierarchy.  *|
     16 |* The declared parameter names are descriptive and specify which type is     *|
     17 |* required. Additionally, each type hierarchy is documented along with the   *|
     18 |* functions that operate upon it. For more detail, refer to LLVM's C++ code. *|
     19 |* If in doubt, refer to Core.cpp, which performs paramter downcasts in the   *|
     20 |* form unwrap<RequiredType>(Param).                                          *|
     21 |*                                                                            *|
     22 |* Many exotic languages can interoperate with C code but have a harder time  *|
     23 |* with C++ due to name mangling. So in addition to C, this interface enables *|
     24 |* tools written in such languages.                                           *|
     25 |*                                                                            *|
     26 |* When included into a C++ source file, also declares 'wrap' and 'unwrap'    *|
     27 |* helpers to perform opaque reference<-->pointer conversions. These helpers  *|
     28 |* are shorter and more tightly typed than writing the casts by hand when     *|
     29 |* authoring bindings. In assert builds, they will do runtime type checking.  *|
     30 |*                                                                            *|
