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 parameter 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. * * @{ */ /** * @defgroup LLVMCCoreTypes Types and Enumerations * * @{ */ typedef int LLVMBool; /* Opaque types. */ /** * The top-level container for all LLVM global data.
