Hello,
I would like to know what is the runtime implementation of arrays used by compilers, and GNAT in particular.
Does an array is represented as an address, a starting index (First) and an ending index (Last) ? Or a First index and a Length.
Is the address the A’First’Address ?
And what about slicing ? Is the address modified ?
And what about passing arrays as reference ?
And what happens when the array is a component of a record :
type OneString (Length : Integer) is
record
Data : String(1 .. Length);
end record;
Is this optimized as a special kind of arrays ?
Is there a paper that discusses these implementation choices ?
Regards,
Vincent
