/* 4.6.3 Relocation codes
*
* S (when used on its own) is the address of the symbol.
* A is the addend for the relocation.
* P is the address of the place being relocated (derived from r_offset).
* X is the result of a relocation operation, before any masking or
* bit-selection operation is applied
* Page(expr) is the page address of the expression expr, defined as
* (expr & ~0xFFF). (This applies even if the machine page size supported
* by the platform has a different value.)
* GOT is the address of the Global Offset Table, the table of code and data
* addresses to be resolved at dynamic link time. The GOT and each entry in
* it must be 64-bit aligned.
* GDAT(S+A) represents a 64-bit entry in the GOT for address S+A. The entry
* will be relocated at run time with relocation R_AARCH64_GLOB_DAT(S+A).
* G(expr) is the address of the GOT entry for the expression expr.
* Delta(S) if S is a normal symbol, resolves to the difference between the
* static link address of S and the execution address of S. If S is the
* null symbol (ELF symbol index 0), resolves to the difference between
* the static link address of P and the execution address of P.
* Indirect(expr) represents the result of calling expr as a function. The
* result is the return value from the function that is returned in r0.
* The arguments passed to the function are defined by the platform ABI.
* [msb:lsb] is a bit-mask operation representing the selection of bits in
* a value. The bits selected range from lsb up to msb inclusive. For
* example, ‘bits [3:0]’ represents the bits under the mask 0x0000000F.
* When range checking is applied to a value, it is applied before the
* masking operation is performed.
