I haven't really looked at this patch, but a few quick notes.
This patch doesn't include documentation patches for the new target
hooks or the new parameters.
The patch is pretty substantial. Can you say something about how it
affects scheduling for non-ia64 targets?
Why does the speculate_insn hook return int rather than bool?
