| * | Update years in copyright notice for the GDB files. | Joel Brobecker | 2013-01-01 | 1 | -1/+1 |
| | | | | | | | | 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. | ||||
| * | Copyright year update in most files of the GDB Project. | Joel Brobecker | 2012-01-04 | 1 | -2/+1 |
| | | | | | | | gdb/ChangeLog: Copyright year update in most files of the GDB Project. | ||||

| * | * mem.c (rx_mem_ptr): When invalidating the decode cache, account | Kevin Buettner | 2010-09-30 | 1 | -3/+9 |
| | | | | | | for the fact that the instruction decoder never uses swapped addresses. | ||||
| * | [include/opcode] | DJ Delorie | 2010-07-29 | 1 | -5/+23 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. | ||||
