For consistency, change the address in the test case from 0xDEADBEEF to 0xCAFEBABE since 0xCAFEBABE that actually has a 2-byte alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183962 91177308-0d34-0410-b5e6-96231b3b80d8

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