    4646by exchanging the order of the two input vectors and modifying
    4747the shuffle selection mask, accordingly.   Second, when
    48 one of the input vectors is a constant vector (the vector of all zeroes {{{zeroinitializer}}}, in this case), then
    49 we can any selection mask index in this vector is equivalent to any other.
     48one of the input vectors is a vector of all zeroes ({{{zeroinitializer}}}), then

    5151This example also illustrates two rules for the conversion to canonical form
    5252in this case.   As described below,  if {{{zeroinitializer}}} occurs
    5353as an input vector, then it should normally occur as the second
    54 input vector.  Secondly, if the selection mask values for a constant
    55 vector always refer to the lowest element.   In the example, the
     54input vector.  Secondly, if the selection mask values for {{{zeroinitializer}}}
     55 always refer to the lowest element.   In the example, the
    5656selection mask values 5 and 6 are replaced by 4.
