Explicit NOPs for a VLIW Machine

[Balaji V. Iyer]

Hi Everyone,
    I am porting GCC 4.0.0 to a proprietary VLIW machine, and I want to
insert NOPs explicitly wherever there is an Output/Flow/Anti dependencies. I
am currently doing this insertion in the machine dependent reorganization
phase. Is there a way to do this in machine description file (or during
scheduling phase) itself (or a better way to do this)?

Thanks,

Balaji V. Iyer.
