| * 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. |

| * README.txt: New. |
| * config.h (CYCLE_ACCURATE, CYCLE_STATS): New. |
| * configure.in (--enable-cycle-accurate, --enable-cycle-stats): |
| New. Default to enabled. |

| (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. |

| |
| * configure.in: Check if the host has getopt.h. |
| * configure: Regenerate. |
| * config.in: Regenerate. |
| * main.c: Include config.h. |
| Use HAVE_STDLIB_H, HAVE_UNISTD_H, HAVE_GETOPT_H. |
