well, there were two patches.  I have managed to update and push
trough one of them in time
(http://gcc.gnu.org/ml/gcc-patches/2011-11/msg00086.html) but
unfortunately I have not managed to do the same with the second one.
It's recent incarnation is here: 

http://gcc.gnu.org/ml/gcc-patches/2011-11/msg00095.html

However, since the stage 1 ended and I still wasn't able to
demonstrate any real impact anywhere (other than my semi-silly example
attached to that patch), I gave up.  It is unfortunate but I also had
other pressing tasks and the patch does not do anything on simple
programs and I have not been able to compile Firefox even without LTO
with the current trunk to try it on something complex.

Therefore at the moment I see no other option but to queue it to stage 1
again.

Thanks,

Martin
