SHL (scalar)

Shift Left (immediate).

Syntax

SHL Vd, Vn, #shift

Where:

V
Is a width specifier, D.
d
Is the number of the SIMD and FP destination register.
n
Is the number of the first SIMD and FP source register.
shift
Is the left shift amount, in the range 0 to 63.

Usage

Shift Left (immediate). This instruction reads each value from a vector, right shifts each result by an immediate value, writes the final result to a vector, and writes the vector to the destination SIMD and FP 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.
