[include/opcode]
* 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.
