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