30// directly give them their exact sizes. We don't need to worry about
31// endianness because these are just the types in the YAMLIO structures,
32// and are appropriately converted to the necessary endianness when
33// reading/generating binary object files.
34// The naming of these types is intended to be ELF_PREFIX, where PREFIX is
35// the common prefix of the respective constants. E.g. ELF_EM corresponds
36// to the `e_machine` constants, like `EM_X86_64`.
37// In the future, these would probably be better suited by C++11 enum
38// class's with appropriate fixed underlying type.
