At least I can say that our f-cpu port (underway) would appreciate
it too. It uses indirect jumps only (like SHmedia) and has different
insn to manipulate code and data pointers because it starts (D/I)TLB
and cache prefetches early (so that pointer manipulation instructions
has one bit to indicate whether to fill D or I cache and whether to use
D or I TLB).
