We still have the problem of when is the goto_tb link initialized the *first* time? Where we expect the goto_tb to fall through to stuff+exit_tb? For i386 it's during translation, with no care for re-translation. For ARM? I can't see that it is. For PPC, malc has already verified that it *never* happens. If he puts "trap" insns there instead of "nop" insns, he'll see the trap. r~
