32 -- This package contains generic procedures for vector operations on arrays.
33 -- If the arguments are aligned on word boundaries and the word size is a
34 -- multiple M of the element size, the operations will be done M elements
35 -- at a time using vector operations on a word.
36
37 -- All routines assume argument arrays have the same length, and arguments
38 -- with mode "in" do not alias arguments with mode "out" or "in out".
39 -- If the number N of elements to be processed is not a multiple of M
40 -- the final N rem M elements will be processed one item at a time.
