Note that there is no requirement at all that this work, but it is not surprising to find that it would work (accidentally? is it documented, I am not sure that it is properly documented for GNAT either come to think about it) since it is an obvious way of implementing things. All the more reason for the ARG to insist on it. There are issues of what types it can be applied to. Shift operations applied for example to non-binary modular types are quite a puzzle. In GNAT, we allow shifts to be applied to any signed or binary unsigned integer type whose size is 8, 16, 32, or 64 (i.e. natural machine sizes for which shifts make sense). It would be interesting to know what restrictions other compilers impose on this usage. -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
