38 *
39 * This modules provide an interface to libLLVMCore, which implements
40 * the LLVM intermediate representation as well as other related types
41 * and utilities.
42 *
43 * LLVM uses a polymorphic type hierarchy which C cannot represent, therefore
44 * parameters must be passed as base types. Despite the declared types, most
45 * of the functions provided operate only on branches of the type hierarchy.
46 * The declared parameter names are descriptive and specify which type is
47 * required. Additionally, each type hierarchy is documented along with the
48 * functions that operate upon it. For more detail, refer to LLVM's C++ code.
49 * If in doubt, refer to Core.cpp, which performs parameter downcasts in the
50 * form unwrap<RequiredType>(Param).
51 *
52 * Many exotic languages can interoperate with C code but have a harder time
53 * with C++ due to name mangling. So in addition to C, this interface enables
54 * tools written in such languages.

1086 * functions are defined by a macro, so it isn't obvious which are
1087 * available by looking at the Doxygen source code. Instead, look at the
1088 * source definition of LLVM_FOR_EACH_VALUE_SUBCLASS and note the list
1089 * of value names given. These value names also correspond to classes in
1090 * the llvm::Value hierarchy.
