That has been posted in stage 1, so it is certainly ok to commit it even
during early stage 3.  And, on a case by case basis exceptions are always
possible.  This hasn't changed in the last few years.  By the reviewed
shortly after the freeze I just want to say that e.g. having large intrusive
patches posted now, but reviewed late December is already too late.

As for postponing end of stage 1 by a few weeks because of the storm, I'm
afraid if we want to keep roughly timely releases we don't have that luxury.
If you look at http://gcc.gnu.org/develop.html, ending stage 1 around end of
October happened already for 4.6 and 4.7, for 4.5 if was a month earlier and
for 4.4 even two months earlier.  The 4.7 bugfixing went IMHO smothly, but
we certainly have to expect lots of bugfixing.

I agree with Eric that it is better to enable it for the whole target
together, rather than based on some options.  Enabling LRA in early stage 3
for some targets should be ok, if it doesn't require too large and intrusive
changes to the generic code that could destabilize other targets.
