Are these IA32, AMD64, IA64 so-called Instruction Set Architectures (a.k.a. macro-architectures)?
By my understanding, IA32 and IA64 are distinct ISAs. x86 is what IA32 used to be called before the advent of IA64 (and the name still sticks around because it's familiar), and x86-64 is IA32 extended to use 64-bit registers.
