E.g. the hppa-linux-user port. The initial merge ends at ebe9383caefd. There are 15 patches -- mostly in linux-user -- before the one that enables compilation. At which point exactly zero instructions are actually implemented. The actual cpu emulation comes afterwards in 8 patches (hppa 1.1 isn't terribly complicated). r~
