MOV (register)

Move register value

This instruction copies the value in a source register to the destination register.

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

313029282726252423222120191817161514131211109876543210
sf0101010000Rm00000011111Rd
opcshiftNimm6Rn

Encoding for the 32-bit variant

Applies when (sf == 0)

MOV <Wd>, <Wm>

is equivalent to

ORR <Wd>, WZR, <Wm>

and is always the preferred disassembly.

Encoding for the 64-bit variant

Applies when (sf == 1)

MOV <Xd>, <Xm>

is equivalent to

ORR <Xd>, XZR, <Xm>

and is always the preferred disassembly.

Assembler Symbols

<Wd>

Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field.

<Wm>

Is the 32-bit name of the general-purpose source register, encoded in the "Rm" field.

<Xd>

Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.

<Xm>

Is the 64-bit name of the general-purpose source register, encoded in the "Rm" field.
