// Test that we produce the correct relocation.
// FIXME: move more relocation only tests here.

// Check prefixes:
// RELOC - Check the relocation in the object.
// FIXUP - Check the fixup on the instruction.
// ENCBE - Check the big-endian encoding on the instruction.
// ENCLE - Check the little-endian encoding on the instruction.
// ????? - Placeholder. Relocation is defined but the way of generating it is
//         unknown.
// FIXME - Placeholder. Generation method is known but doesn't work.
