ARM was never THAT risc to start with, with instructions that load from memory + increment pointers (have to be split into 2 micro-ops), bitshift+add, multiply+accumulate, conditional versions of everything, or load/store multiple registers. But it does have a good balance, yes.
You're not real CISC until you have an instruction for sprintf() anyway (IBM S/360 in 1964, all the way to modern z/Arch): http://planetmvs.com/hlasm/s390faq.html#ed … Other fun insns: CUTFU (Convert UTF-8 to UTF-16), EX (Execute, like eval()), UPT (Update Tree - yes, this walks a binary tree)

So the modern Java/.NET/Dalvik bytecodes aren't really as new as they seem? May have to dig into S/360. Thanks.
