Just some suggestions:
Drop a tag before the commit. For the MIPS I went as far as creating
branch since I know I'm going to adding debug code to it so I can figure
out why obscure target xyz broke. I suspect for here a branch is over
Since there is a BFD dependency you'll need to wait for that (sigh :-).
It may be possible to carve up this patch and get some of it in
immediatly. I guess, wait and see.
As for the "core-file <file>" problem. It will need a little thought.
The theory is that, eventully, an architecture will be bound to each
``thread''. An interum solution could have the architecture bound to
