Re: Speculative prefetching: report

  Before pushing it to mainline I would like see the
quadratic bottlenect of bsi_for_stmt resolved.  I don't know where the
discussion surrounding Zdenek's patch went but I guess without that we
can fix it by keeping around BSIs instead of direct statement pointers
in the interface that is straightforward change.

No, I tried that and could not get it to work. The problem was that once
you've expanded one tree nearby stored bsi's become useless.

Besides, storing 3-word bsi's all over the place is not a good thing.
