The A64 instruction set is used when executing in the AArch64 Execution state. It is a fixed- arm instructions are fixed size, there is simply no room to load a full 64 bit immediate. You either load from memory (literal pool) or you put it together from parts. The various relocation types are tailored to particular instruction formats.
