MOV (SIMD&FP scalar, unpredicated)

Operation

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

Operational information

If FEAT_SVE2 is implemented or FEAT_SME is implemented, then 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.

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.

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

The encodings in this description are named to match the encodings of DUP (indexed).

The description of DUP (indexed) gives the operational pseudocode, any constrained unpredictable behavior, and any operational information for this instruction.

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.

MOV <Zd>.<T>, <V><n>
is equivalent to

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

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