Software Pipelining in GCC


Hi, Jim.

I'm going to implement software pipelining (SWP)in GCC
on platforms with hardware support (eg. IA64). But I'm
afraid of it may be a duplicate work.

According to the GCC mailing list, some people have
already worked on it, and had done modulo schedule and
rotating register allocation in last year. But I can't
contact with them due to their outdated mailboxes. So,
how is the implementation of SWP in GCC going on?

If you know anything about that, or have suggestions
about the implementation of SWP in GCC, would you mind
telling me? I'm very appreciate it.

Regards,
Canqun Yang.
