Hi Vlad,Sorry for the delay with the answer. I was thinking about this. I did
not know what to do with this code. I read that somebody was going to
use it for a gcc port. But I am not sure about this.
You added code to haifa-sched to allow it to insert NOPs, but
insert_schedule_bubbles_p is 0 for all targets. Also, the target hooks
are not defined by any target.
You merged this code more than two years ago. Do you have plans to
start using it, or can I post a patch to remove it?
In my opinion, we don't these code now. It is not used in public gcc
and it complicates the scheduler. If somebody decided to use it for a
port, the code could be committed again with the port.
So you can post a patch to remove it.
