* 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.

* 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.
2010-07-07 * gdb-if.c (sim_store_register): Add case for sim_rx_acc_regnum.Kevin Buettner2-0/+8
2010-06-24Add "acc" register. Revise register order and names.Kevin Buettner2-0/+12
2010-06-08oops - omitted from previous deltaNick Clifton1-0/+5
2010-06-08 * reg.c (set_oszc): Use unsigned int for the mask.Nick Clifton1-4/+4

2010-05-28Revert accidentally committed changes that aren't ready yet.Kevin Buettner1-7/+0
2010-05-28 * gdb-if.c (sim_do_command): Add a "sim verbose noisy" command.Kevin Buettner2-1/+14
2010-04-14sim: constify sim_write source buffer (part 2)Mike Frysinger2-1/+5
As pointed out by Sandra Loosemore, a bunch of targets define sim_write themselves instead of using the common/ code. So constify them too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-02-14 * configure.in: Check if the host has getopt.h.Masaki Muranaka5-0/+138
* configure: Regenerate. * config.in: Regenerate. * main.c: Include config.h. Use HAVE_STDLIB_H, HAVE_UNISTD_H, HAVE_GETOPT_H. Include getopt.h in case HAVE_GETOPT_H is defined.
