Won't work, the asm needs to be inlined because it needs to:

1) Know where local variables are located

2) Has to run in the context of the stack frame the
   call site runs in so that the tail-call it's doing works

And actually all of this is why the sparc64 fix turned out to
be so invasive, and I'll need to do the same for sparc32
as a result.
