I'd like to suggest there is still no reason not to take the current
work (with suggested changes), which interested parties can then further
adapt for supporting other/multiple architectures. There is virtually
no new architecture-specific code that would have to be redone later.
Additionally, it's not clear to me how useful instruction interpretation
is to any other architecture. We are doing this only because 32-bit ARM
does not support single-stepping.
