25 // These types are invariant across 32/64-bit ELF, so for simplicity just
26 // directly give them their exact sizes. We don't need to worry about
27 // endianness because these are just the types in the YAMLIO structures,
28 // and are appropriately converted to the necessary endianness when
29 // reading/generating binary object files.
30 // The naming of these types is intended to be ELF_PREFIX, where PREFIX is
31 // the common prefix of the respective constants. E.g. ELF_EM corresponds
32 // to the `e_machine` constants, like `EM_X86_64`.
33 // In the future, these would probably be better suited by C++11 enum
34 // class's with appropriate fixed underlying type.
