Yes. It's not a virtual machine in the VMware sense where there's native execution or in the QEMU sense where there's dynamic translation to native code. M5 is most like an interpreter, and it can interpret any implemented ISA on any ISA M5 can run on generally, less the occasional endianness/alignment/etc. bug. > I get confused by the following too.

They don't (or at least shouldn't) get built into the simulator if they don't match the ISA that's being built. X86_FS doesn't use arch/sparc, for example.
