SMOV (vector)
Signed Move vector element to general-purpose register.
Syntax
SMOV
Wd, Vn.Ts[index] ; 32-bit
SMOV
Xd, Vn.Ts[index] ; 64-bit
Where:
Wd- Is the 32-bit name of the general-purpose destination register.
Ts-
Is an element size specifier:
- 32-bit
-
Can be one of
BorH. - 64-bit
-
Can be one of
B,HorS.
index- Is the element index, in the range shown in Usage.
Xd- Is the 64-bit name of the general-purpose destination register.
Vn- Is the name of the SIMD and FP source register.
Usage
Signed Move vector element to general-purpose register. This instruction reads the signed integer from the source SIMD and FP register, sign-extends it to form a 32-bit or 64-bit value, and writes the result to destination general-purpose 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.
