WOOHOO!!! Impressive stuff, congrats Michael.
What works: * unregisterized compilation: I had to be a bit creative with the LOOKS_LIKE_GHC_INFO stuff (which is one fragile piece of sh^H^Hcode... ;)),
You'll be glad to know that all going according to plan, we'll be able to remove this dependency from the RTS before too long. We're planning some changes to the tail-call mechanism that means stack-walking will no longer need to be able to distinguish between code and data pointers.
* make bootstrapping work with uh... less hand-waving, praying/swearing in the general direction of Glasgow, etc. ;)
We're definitely interested in doing this. BTW, swearing at Glasgow won't get you very far, since we're in Cambridge :-p Cheers, Simon
