25 * @defgroup LLVMC LLVM-C: C interface to LLVM
27 * This module exposes parts of the LLVM library as a C API.
33 * @defgroup LLVMCTransforms Transforms
37 * @defgroup LLVMCCore Core
39 * This modules provide an interface to libLLVMCore, which implements
40 * the LLVM intermediate representation as well as other related types
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).
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.
