Neonint32x2_tvqabs_s32(int32x2_t a)Vector arithmetic / Absolute / Saturating absolute value
Description
Signed saturating Absolute value. This instruction reads each vector element from the source SIMD&FP register, puts the absolute value of the result into a vector, and writes the vector to the destination SIMD&FP register. All the values in this instruction are signed integer values.

    element = SInt(Elem[operand, e, esize]);
    if neg then
        element = -element;
    else
        element = Abs(element);
    (Elem[result, e, esize], sat) = SignedSatQ(element, esize);         
    if sat then FPSR.QC = '1';
