How to fill delay slot for a VLIW target?

[Jeff Chen]

i am porting GCC for a VLIW target, the target has six slots, it can 
issue at most 6 insns in one cycle. the branch, and call insn requires a 
delay slot of one VLIW bundle. i want to use define_delay to handle 
filling of delay slot. but define_delay can only describe insns which 
need a FIXED number of delay slots, in my case, the number of insns in 
the delay slot (which forms a VLIW bundle) may VARY.

it seems that GCC schedules delay slot on the basis of insn, not on VLIW 
bundle, so is it possible to use define_delay for such a VLIW target?
