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.
Move vector element to scalar. This instruction duplicates the specified vector element in the SIMD&FP source register into a scalar, and writes the result to the SIMD&FP destination register.

This is an alias of DUP (element). This means:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
0 | 1 | 0 | 1 | 1 | 1 | 1 | 0 | 0 | 0 | 0 | imm5 | 0 | 0 | 0 | 0 | 0 | 1 | Rn | Rd |
is equivalent to
and is always the preferred disassembly.
<d> | Is the number of the SIMD&FP destination register, encoded in the "Rd" field. |
<Vn> | Is the name of the SIMD&FP source register, encoded in the "Rn" field. |
<T> |
Is the element width specifier,
encoded in
imm5:
| ||||||||||||
|
<index> |
Is the element index
encoded in
imm5:
