I'm not sure how this would help: do you have optimizations that we
can apply specifically to gc-leaf functions?

While refactoring my code to use statepoints, I noticed that I was
alloca'ing things like global string pointers, while malloc'ing things
like arrays; but since my language is untyped, I was boxing them up in
a malloc'ed structure. The problem doesn't affect me in practice
because I'm always passing around boxed objects, but I was wondering
if others who are doing typed languages would need an addrspaceany.

You don't see the need for it, so I suppose the discussion is closed
until someone does.
