See System.Generic_Vector_Operations. 34 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. 40 41package System.Vectors is 42 pragma Pure; 43 44 type Vector is mod 2**System.Word_Size; 45 for Vector'Alignment use Integer'Min 46 (Standard'Maximum_Alignment, System.Word_Size / System.Storage_Unit); 47 for Vector'Size use System.Word_Size; 48 49end System.Vectors; 50
