54/// A Module instance is used to store all the information related to an
55/// LLVM module. Modules are the top level container of all other LLVM
56/// Intermediate Representation (IR) objects. Each module directly contains a

58/// other modules) this module depends on, a symbol table, and various data
59/// about the target's characteristics.
