I think there are two natural approaches. 1) Do the VLIW bundling after delayed branch scheduling. The way to do that is to the bundling in TARGET_ASM_FUNCTION_PROLOGUE. The FRV backend does this. I've done this successfully in the past. 2) When you do the VLIW bundling, put the instructions into a PARALLEL. In general the gcc scheduler does not handle VLIW scheduling very well, and it needs a fair amount of target specific help. Ian
