MOV (scalar)
Move vector element to scalar.
This instruction is an alias of DUP (element).
The equivalent instruction is DUP .Vd, Vn.T[index]
Syntax
MOV
Vd, Vn.T[index]
Where:
V- Is the destination width specifier, and can be one of the values shown in Usage.
d- Is the number of the SIMD and FP destination register.
Vn- Is the name of the SIMD and FP source register.
T- Is the element width specifier, and can be one of the values shown in Usage.
index- Is the element index, in the range shown in Usage.
Usage
Move vector element to scalar. This instruction duplicates the specified vector element in the SIMD and FP source register into a scalar, and writes the result to the SIMD and FP destination register.
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.
The following table shows the valid specifier combinations:
