Dominator Information in new-ra

[Mukta Punjani, Noida]

Hi,

I want to use the dominator tree information in the data flow pass(df.c) for
implementing rematerialization in new-ra.

The dominator information being built in
dominance.c:calculate_dominance_info() is being called in ra-ranges.c. But
apparently functions in ra-ranges.c are not being used currently. Are there
any plans of using the code from ra-ranges.c in new-ra.

Thanks for any inputs.

Best Regards,
Mukta
