I probably will; 2/5 (the "rip" patch) needs updating, and my patch stack is much too high :-) Not that [34]/5 do terribly much without 2/5. Thanks for all the reviews, Segher

This makes PARALLELs not lose their LOG_LINKS early when e.g. a trivial reg-reg move is combined, so that they can be used in more useful combinations as well. 2014-11-14 Segher Boessenkool gcc/ * combine.c (distribute_links): Handle multiple SETs. So the code in distribute_links implies that we're not going to see hard register SUBREGs, so ignore my concerns with the prior patch in this series WRT hard register SUBREGs. This is OK once prereqs are approved. You might consider pushing the two LOG_LINKs related patches forward independently of the patch to rip apart the PARALLELs. Though I think that all of the patches are pretty close to being approved. Your call. Jeff
