This is _not_ unexpected with different processor architectures, and thus different instruction sets. Speculation: the values lfor the .LC* variables look like bit-masks -- it may be that ia64 has opcodes that allow immediate operannds, obviating the need for a 'data' consntat in memory. "Something" in the source causes different processor-specific code to be generated -- one processor uses 'data' constants, the other doesn't. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
