Hi Steve,

No, it was relatively close, but an issue with reordering became
visible and changed the disposition.

That reordering issue is quite hard to address, the latest update I sent is
here:

http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20150914/299491.html

I'm afraid getting such changes in will take a lot of time too...  And
that patch is far from being complete as it's missing new instructions and thus
changes for all the targets (I'm getting there, or at least I think so).

Regards,
Sergey
