+ * config/mips/driver-native.c [__sgi__]: Include <invent.h>,
+ <sys/sbd.h>.
+ (cpu_types): New array.
+ (cputype): New function.
+ (host_detect_local_cpu): Only define buf, f if !__sgi__.
+ Use scaninvent instead of /proc/cpuinfo if __sgi__.
+ * config.host: Also use driver-native.o, mips/x-native on
+ mips-sgi-irix*.
+ * config/mips/iris6.h [__mips__] (host_detect_local_cpu):
+ Declare.
+ (EXTRA_SPEC_FUNCTIONS, MARCH_MTUNE_NATIVE_SPECS): Define.
+ (DRIVER_SELF_SPECS): Add MARCH_MTUNE_NATIVE_SPECS.
