Re: Scheduling and inserting NOPs

Is there some special reason you can't do this in machine dependent

block stuffing NOPs.

The problem isn't where, it's how. The insn-list after scheduling doesn't provide any information about cycles or delays, does it? How do I find out before which insn I have to insert a NOP, if the scheduler doesn't pass any info to me?
