| -- This package defines a datatype which is most efficient for performing |
| -- logical operations on large arrays. 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; |
| |
| 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; |
