(accg4567_regnum, msr0_regnum, msr1_regnum, gner0_regnum) (gner1_regnum, fner0_regnum, fner1_regnum, accg0_regnum) (accg7_regnum): New constants. (last_spr_regnum, last_pseudo_regnum): Update. * frv-tdep.c (new_variant): Initialize names for fsr0, acc0-acc7, accg0-accg7, msr0, msr1, gner0, gner1, fner0, and fner1. (frv_pseudo_register_read, frv_pseudo_register_write): Add support for accg registers. (frv_register_sim_regno): Update spr_map[].
