+
+       * rx.c (decode_cache_base): New.
+       (id_names): Remove ediv and edivu.
+       (optype_names): Add TwoReg.
+       (maybe_get_mem_page): New.
+       (rx_get_byte): Call it.
+       (get_op): Add TwoReg support.
+       (put_op): Likewise.
+       (PD, PS, PS2, GD, GS, GS2, DSZ, SSZ, S2SZ, US1, US2, OM): "opcode"
+       is a pointer now.
+       (DO_RETURN): New.  We use longjmp to return an exception result.
+       (decode_opcode): Make opcode a pointer to the decode cache.  Save
+       decoded opcode information and re-use.  Call DO_RETURN instead of
+       return throughout.  Remove ediv and edivu.
+       * mem.c (ptdc): New.  Adds decode cache.
+       (rx_mem_ptr): Support it.
+       (rx_mem_decode_cache): New.
+       * mem.h (enum mem_ptr_action): add MPA_DECODE_CACHE.
+       (rx_mem_decode_cache): Declare.
+       * gdb-if.c (sim_resume): Add decode_opcode's setjmp logic here...
+       * main.c (main): ...and here.  Use a fast loop if neither trace
+       nor disassemble is given.
+       * cpu.h (RX_MAKE_STEPPED, RX_MAKE_HIT_BREAK, RX_MAKE_EXITED,
+       RX_MAKE_STOPPED, RX_EXITED, RX_STOPPED): Adjust so that 0 is not a
+       valid code for anything.
