32 -- This package defines a datatype which is most efficient for performing
33 -- logical operations on large arrays. See System.Generic_Vector_Operations.
35 -- In the future this package may also define operations such as element-wise
36 -- addition, subtraction, multiplication, minimum and maximum of vector-sized
37 -- packed arrays of Unsigned_8, Unsigned_16 and Unsigned_32 values. These
38 -- operations could be implemented as system intrinsics on platforms with
39 -- direct processor support for them.
