Apologies for the rather pronounced radio silence up until now, but I have been working with Eckhardt to produce a strategy paper. It identifies what seem to be key hurdles for getting the QEMU code generator working on Plan 9 (under kencc) and proposes at least one and usually more solution per problem.
I would deeply appreciate feedback from any and all interested parties. My email address is email@example.com.
[Update: now using the absolute path for the paper. Thanks to Oksel for pointing out the need.]
