Nettetis the register on which the memory address is based. offset is an offset. If offset is omitted, the address is the contents of Rn. Rt2 is the additional register to load for doubleword operations. Not all options are available in every instruction set and architecture. Offset ranges and architectures NettetThe offset (if used) must be a constant and the base and index (if used) must be registers; the scale must be either 1, 2, 4, or 8. The default offset, base, and index are 0, and the default scale is 1. symbol_names are found only in compiler-generated assembly; disassembly uses raw addresses (0x601030) or %rip-relative offsets (0x200bf2(%rip)).
