	Vector Test Bits takes each element in a vector, and bitwise ANDs it with the corresponding element of a second vector. If the result is not zero, the corresponding element in the destination vector is set to all ones. Otherwise, it is set to all zeros. The operand vector elements can be any one of: • 8-bit, 16-bit, or 32-bit fields. The result vector elements are fields the same size as the operand vector elements. Depending on settings in the CPACR, NSACR, and HCPTR registers, and the security state and mode in which the instruction is executed, an attempt to execute the instruction might be UNDEFINED, or trapped to Hyp mode. Summary of access controls for Advanced SIMD functionality on page B1-1232 summarizes these controls. ARM deprecates the conditional execution of any Advanced SIMD instruction encoding that is not also available as a VFP instruction encoding, see Conditional execution on page A8-288.
