If bool x:1 has the size of bool, then wouldn't int x:1 have the size of int? But my little experiments suggest that the size is the smallest that fits the requested bits and alignment chosen by the compiler, regardless of the type. bool x:1 has the advantage that anything that is not 0 is considered true. So for bool x:1, x = 4 is true, while for int x:1, x = 4 is false. But the :1 adds instructions, so at least for only one bool, where little space is saved, it is probably not worth it. julia _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
