MOV (SIMD&FP scalar, unpredicated)

Move indexed element or SIMD&FP scalar to vector (unpredicated)).

Unconditionally broadcast the SIMD&FP scalar into each element of the destination vector. This instruction is unpredicated.

.

Unconditionally broadcast the SIMD&FP scalar into each element of the destination vector. This instruction is unpredicated.

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

313029282726252423222120191817161514131211109876543210
00000101imm21tsz001000ZnZd

MOV <Zd>.<T>, <V><n>

is equivalent to

DUP <Zd>.<T>, <Zn>.<T>[0]

and is the preferred disassembly when BitCount(imm2:tsz) == 1.

MOV <Zd>.<T>, <Zn>.<T>[<imm>]

is equivalent to

DUP <Zd>.<T>, <Zn>.<T>[<imm>]

and is the preferred disassembly when BitCount(imm2:tsz) > 1.

Assembler Symbols

<Zd>

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

<T>

<n>

Is the number [0-31] of the source SIMD&FP register, encoded in the "Zn" field.
