MOV (scalar, unpredicated)

Move general-purpose register to vector elements (unpredicated).

Unconditionally broadcast the general-purpose scalar source register into each element of the destination vector. This instruction is unpredicated.

This is an alias of DUP (scalar). This means:

  • The encodings in this description are named to match the encodings of DUP (scalar).
  • The description of DUP (scalar) gives the operational pseudocode for this instruction.

MOV <Zd>.<T>, <R><n|SP>

is equivalent to

DUP <Zd>.<T>, <R><n|SP>

and is always the preferred disassembly.

Assembler Symbols

<Zd>

Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T> Is the size specifier, encoded in size:
size <T>
00 B
01 H
10 S
11 D
<R> Is a width specifier, encoded in size:
size <R>
01 W
x0 W
11 X
<n|SP>

Is the number [0-30] of the general-purpose source register or the name SP (31), encoded in the "Rn" field.

Operation

The description of DUP (scalar) gives the operational pseudocode for this instruction.

Operational information

If PSTATE.DIT is 1:

  • The execution time of this instruction is independent of:
    • The values of the data supplied in any of its registers.
    • The values of the NZCV flags.
  • The response of this instruction to asynchronous exceptions does not vary based on:
    • The values of the data supplied in any of its registers.
    • The values of the NZCV flags.
