MOV (scalar, unpredicated)

Move general-purpose register to vector elements (unpredicated)

This instruction unconditionally broadcasts 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, any constrained unpredictable behavior, and any operational information for this instruction.

Encoding

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>
00	W
01	W
10	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.
