2010-11-11 DJ Delorie <dj@redhat.com>
* rx.c (lsb_count): New.
(divu_cycles): New.
(div_cycles): New.
(decode_opcode): Fix cycle count math for div, divu, suntil, and
swhile.
2010-09-29 Kevin Buettner <kevinb@redhat.com>
* mem.c (rx_mem_ptr): When invalidating the decode cache, account
for the fact that the instruction decoder never uses swapped
addresses.
2010-09-29 Nick Clifton <nickc@redhat.com>
* rx.c (decode_opcode: RXO_int): Only break out of the emulation
loop if rx_syscall() does not return a RX_STEPPED result.
2010-09-23 Kevin Buettner <kevinb@redhat.com>
* rx.c (decode_opcode): Add cycle information for RXO_smovu.
2010-09-23 Kevin Buettner <kevinb@redhat.com>
* fpu.c, gdb-if.c, load.c, misc.c, syscalls.c (config.h): Include.
* rx.c (decode_opcode): Declare `tx' as unsigned.
* cpu.h (reset_decoder): Declare.
* load.c (rx_load): Call `reset_decoder'.
* rx.c (reset_decoder): New function.
2010-07-29 DJ Delorie <dj@redhat.com>
* 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.
2010-07-27 DJ Delorie <dj@redhat.com>
* README.txt: New.
* config.h (CYCLE_ACCURATE, CYCLE_STATS): New.

(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.
