20.11 BIT (vector)

Bitwise Insert if True.

Syntax

BIT Vd.T, Vn.T, Vm.T

Where:

Vd
Is the name of the SIMD and FP destination register.
T
Is an arrangement specifier, and can be either 8B or 16B.
Vn
Is the name of the first SIMD and FP source register.
Vm
Is the name of the second SIMD and FP source register.

Usage

Bitwise Insert if True. This instruction inserts each bit from the first source SIMD and FP register into the SIMD and FP destination register if the corresponding bit of the second source SIMD and FP register is 1, otherwise leaves the bit in the destination register unchanged.

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.
