MOV (from general)
Move general-purpose register to a vector element. This instruction copies the contents of the source general-purpose register to the specified vector element in the destination SIMD&FP register.
This instruction can insert data into individual elements within a SIMD&FP register without clearing the remaining bits to zero.
Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
This is an alias of INS (general). This means:
- The encodings in this description are named to match the encodings of INS (general).
- The description of INS (general) gives the operational pseudocode for this instruction.

MOV <Vd>.<Ts>[<index>], <R><n>
is equivalent to
INS <Vd>.<Ts>[<index>], <R><n>
and is always the preferred disassembly.

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.
