MOV (register)

Move (register) copies the value in a source register to the destination register.

This is an alias of ORR (shifted register). This means:

313029282726252423222120191817161514131211109876543210
sf0101010000Rm00000011111Rd
opcshiftNimm6Rn

32-bit (sf == 0)

MOV <Wd>, <Wm>

is equivalent to

ORR <Wd>, WZR, <Wm>

and is always the preferred disassembly.

64-bit (sf == 1)

MOV <Xd>, <Xm>

is equivalent to

ORR <Xd>, XZR, <Xm>

and is always the preferred disassembly.

Assembler Symbols
