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