GCC ports with more than one delay-slot are SOL; there be bugs. (No port in the official repository has more than one delay-slot, so if reorg.c ever was bug-free in that regard, there's little chance to spot any regression. It might even be sanity-preserving to erroring out (or emitting a warning) in genwhatever for such a define_delay.) Sorry! brgds, H-P
