Can I use SCHED_GROUP_P to make the VLIW bundle in the final pass?

[Ling-hua Tseng]

I'm porting the GCC 4.0.x snapshots to a VLIW architecture.
Currently, I need to bundle the instructions.

I want to use the "%P" (means parallel execution with the next insn) in the output template of
(define_insn ...) in the MD, and I want to use the SCHED_GROUP_P to determine whether
the next insn should be bundled with the current insn (by filling out the %P in the PRINT_OPERAND) .

Is this a correct solution for me?
Thanks a lot.
