Our current behaviour is "auto", which means "send semihosting commands via gdb if and only if the gdbstub has a gdb connected when the first semihosting command is made by the guest". "native" would mean "handle semihosting ourselves even if there's a gdb connected". I'm not sure how useful "gdb" is as distinct from "auto" (what do you do with the semihosting requests if no gdb is connected in this case?). -- PMM
