I've noticed that even the latest version of haifa-sched.c (the one in the CVS)
still does not support software pipelining and branch
optimizations (These features appear even in the "GCC news and announcements"
section for September 22, 1998).
Does anyone know where is it possible to download an updated version of this
file that contains such improvements?

Barak.
