MOV (immediate, unpredicated)

.

Unconditionally broadcast the signed integer immediate into each element of the destination vector. This instruction is unpredicated.

The immediate operand is a signed value in the range -128 to +127, and for element widths of 16 bits or higher it may also be a signed multiple of 256 in the range -32768 to +32512 (excluding 0).

The immediate is encoded in 8 bits with an optional left shift by 8. The preferred disassembly when the shift option is specified is "#<simm8>, LSL #8". However an assembler and disassembler may also allow use of the shifted 16-bit value unless the immediate is 0 and the shift amount is 8, which must be unambiguously described as "#0, LSL #8".

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

313029282726252423222120191817161514131211109876543210
00100101size11100011shimm8Zd

MOV <Zd>.<T>, #<imm>{, <shift>}

is equivalent to

DUP <Zd>.<T>, #<imm>{, <shift>}

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>
00B
01H
10S
11D
<T>

Is the size specifier, encoded in size:

size<T>
00B
01H
10S
11D
<imm>

Is a signed immediate in the range -128 to 127, encoded in the "imm8" field.

<shift> Is the optional left shift to apply to the immediate, defaulting to LSL #0 and encoded in sh:
sh<shift>
0LSL #0
1LSL #8
<shift>

Is the optional left shift to apply to the immediate, defaulting to LSL #0 and encoded in sh:

sh<shift>
0LSL #0
1LSL #8
