Hi.

  This patch removes obsolete PREFERRED_RELOAD_CLASS and 
PREFERRED_OUTPUT_RELOAD_CLASS macros from MMIX back end in the GCC and 
introduces equivalent TARGET_PREFERRED_RELOAD_CLASS and
TARGET_PREFERRED_OUTPUT_RELOAD_CLASS target hooks.

  Regression tested on mmix-knuth-mmixware.

  OK to install?

        * config/mmix/mmix.h (PREFERRED_RELOAD_CLASS,
        PREFERRED_OUTPUT_RELOAD_CLASS): Remove macro.
        * config/mmix/mmix-protos.h (mmix_preferred_reload_class,
        mmix_preferred_output_reload_class): Remove.
        * config/mmix/mmix.c (mmix_preferred_reload_class,
        mmix_preferred_output_reload_class): Make static. Change rclass
        argument and return type to reg_class_t.
        (TARGET_PREFERRED_RELOAD_CLASS,
        TARGET_PREFERRED_OUTPUT_RELOAD_CLASS): Define.


Anatoly.
