Subject: Array conversion and bounds
Date: Sun, 15 Apr 2018 11:36:19 +0200
Date: 2018-04-15T11:36:19+02:00	[thread overview]
Message-ID: <pav6el$pg1$1@gioia.aioe.org> (raw)

Do array bounds slide during conversion? Consider this:

    type A is array (Integer range <>) of Whatever;
    type B is array (Unsigned_32 range <>) of Whatever;

    X : A (-10..-1);
    Y : B (1..10);
begin
    Y := B (X); -- Is this OK?

If bounds slide it must be OK, if bounds do not slide, it must raise 
Constraint_Error.

Any language lawyers?
