MOV (to/from SP)
Move between register and stack pointer: Rd = Rn.
This is an alias of ADD (immediate). This means:
- The encodings in this description are named to match the encodings of ADD (immediate).
- The description of ADD (immediate) gives the operational pseudocode for this instruction.

32-bit (sf == 0)
is equivalent to
and is the preferred disassembly when (Rd == '11111' || Rn == '11111').
64-bit (sf == 1)
is equivalent to
and is the preferred disassembly when (Rd == '11111' || Rn == '11111').
Assembler Symbols
