Joel Brobecker 8acc9f485b Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.

DJ Delorie f9c7014e9c [include/opcode]
* rx.h (RX_Operand_Type): Add TwoReg.
(RX_Opcode_ID): Remove ediv and ediv2.

[opcodes]

* rx-decode.opc (SRR): New.
(rx_decode_opcode): Use it for movbi and movbir.  Decode NOP2 (mov
r0,r0) and NOP3 (max r0,r0) special cases.
* rx-decode.c: Regenerate.

[sim/rx]

* 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.

DJ Delorie 933786524e [sim/rx]
* README.txt: New.
* config.h (CYCLE_ACCURATE, CYCLE_STATS): New.
* configure.in (--enable-cycle-accurate, --enable-cycle-stats):
New.  Default to enabled.

* cpu.h (regs_type): Add cycle tracking info.
(reset_pipeline_stats): Declare.
(halt_pipeline_stats): Declare.
(pipeline_stats): Declare.
* main.c (done): Call pipeline_stats().
* mem.h (rx_mem_ptr): Moved to here ...
* mem.c (mem_ptr): ... from here.  Rename throughout.
(mem_put_byte): Move LEDs to Port A.  Add Port B to control cycle
statistics.  Move UART to SCI4.
(mem_put_hi): Add TPU 1-2.  TPU 1 and 2 count CPU cycles.
* reg.c (init_regs): Set Rt reg to -1 (no reg).
* rx.c: Add cycle counting and statistics throughout.
(rx_get_byte): Optimize for speed.
(decode_opcode): Likewise.
(reset_pipeline_stats): New.
(halt_pipeline_stats): New.
(pipeline_stats): New.
* trace.c (sim_disasm_one): Print cycle count.

[include/opcode]
* rx.h (RX_Opcode_ID): Add nop2 and nop3 for statistics.
