Hi,

I'm currently working on an optimization pass, that requires the execution
between instruction selection and scheduling. In addition, this pass is working
on MachineFunction/Function level. Therefore it's necessary, that the
instruction selection for the whole Function is completed before any scheduling
is done.
After the optimization pass had completed it's work, the regular scheduling
should start.
Is there a way to split those two phases and let the instruction selection
complete for all basic blocks, before the scheduling starts?

A second question: Requires the instruction selection of a basic block the
completion of scheduling of previous basic blocks?

Regards,

Patrick
