[LLVMdev] MachineBasicBlocks Cloning

For some schedulers like Trace Scheduling it is necessary to clone basic blocks.
Instinctively I would think the "Machine Instruction Scheduler" would be the right place to do so.

Is it possible to clone MachineBasicBlocks in the "Machine Instruction Scheduler" pass? Any snares? Or is it to much effort to implement it there and there is a better place for such things?

Thank you,
