See System.Generic_Vector_Operations. -- In the future this package may also define operations such as element-wise -- addition, subtraction, multiplication, minimum and maximum of vector-sized -- packed arrays of Unsigned_8, Unsigned_16 and Unsigned_32 values. These -- operations could be implemented as system intrinsics on platforms with -- direct processor support for them. package System.Vectors is pragma Pure (Vectors); type Vector is mod 2**System.Word_Size; for Vector'Alignment use Integer'Min (Standard'Maximum_Alignment, System.Word_Size / System.Storage_Unit); for Vector'Size use System.Word_Size; end System.Vectors;
