549 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
551 (_ins_type): New enumeration to specify which container an
552 instruction is in, and whether it is part of a parallel operation.

555 (ins_type_counters): Counters for the various instruction types.
556 ({left,right}_nops): Counters for the number of nops in each
558 (d10v_debug): New variable to indicate whether debugging is turned
561 * simops.c: (all functions): Change all #ifdef DEBUG code so that
562 the input and output values can be traced, along with the
563 instruction type. Make the -t option enable tracing.
564 (all functions): Change printf calls to use the printf_filtered
565 function in the callback table.

568 instructions are done left first or right first.
569 (do_{long,2_short,parallel}): Indicate in the machine state which
570 type of instruction this is. Count each of the types of
571 instructions executed.
572 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
574 (sim_resume): Pass left/right indication to do_2_short.
575 (all functions): Change printf calls to use the printf_filtered
576 function in the callback table.

579 (sim_info): Print out statistics on instructions.
580 (sim_{trace,create_inferior}): Eliminate extraneous output unless
582 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
583 Only initialize the hash table the first time sim_open is called.
585 * Makefile.in: Make objects depend on d10v_sim.h.
586 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
587 CFLAGS does not override host/target defines or SIM_CFLAGS.
588 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.

595 ({run,callback}.o): Provide explicit paths to their appropriate
597 (gencode{,.o},d10v-opc.o): Split compilation into creating object
598 and linking. Instead of linking in libopcodes.a, just compile
599 d10v-opc.o directly to handle canadian cross.

604 (CC_FOR_BUILD): Deal with canadian crosses.
