As fwprop is no longer on the table for 4.2, and as the vectorizer

and Dorit's leave, I think it's time to declare 4.2 feature-complete.


I am still waiting for review of by auto-increment patches, and for Berndt
to complete the cross-jump part struct-equiv patches, so that I can post an
updated patch for the if-conversion part.

At this point I think it's better to wait for 4.3. I like neither of the current proposed solutions - mine costs too much compile time, while yours is too much of a hack. A while back I did some CSiBE testing that did not show enough benefit for the loss of compile time. We need to figure out something better.
