As well as the JIT work, I'm hoping to merge the
"dmalcolm/gimple-classes" git branch, which makes moves gimple statement
accessor typechecking from runtime to compile time, by making use of
gimple subclasses:
  https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01380.html

This is a big patch, currently:
 152 files changed, 11166 insertions(+), 4806 deletions(-)
and a followup part of it involves renaming every "gimple" to be a
"gimple *".

doing this refactoring very early in stage3.


I also have some mostly-done RTL subclass work which I hope to post
before stage1 closes (using rtx_insn * in some more places; about
another 20 or so patches).


FWIW I've been investigating generalizing the JIT API to also be usable
as a stable API for plugins (i.e. both extending *and* embedding from
the same API), but at the moment I don't think that work is going to be
ready in time for stage1 close.
