	The "nabs" instruction is allowed on PPC601.  This may be another
case where --with-cpu= does not work well for PowerPC.  MkLinux does not
have a separate configuration for GCC, otherwise you could default to
PPC601 there.  Probably better to use the standard PowerPC model when
building the compiler and explicitly using "-mcpu=601" when compiling
applications.

	insn-recog requires a lot of time and memory to optimize.
