  40
  41         * simops.c: (all functions): Change all #ifdef DEBUG code so that
  42         the input and output values can be traced, along with the
  43         instruction type.  Make the -t option enable tracing.
  44         (all functions): Change printf calls to use the printf_filtered
  45         function in the callback table.
  46
  47         * interp.c (_leftright): New enumeration to say whether 2 short
  48         instructions are done left first or right first.
  49         (do_{long,2_short,parallel}): Indicate in the machine state which
  50         type of instruction this is.  Count each of the types of

  56         function in the callback table.

  59         (sim_info): Print out statistics on instructions.
  60         (sim_{trace,create_inferior}): Eliminate extraneous output unless

  64
  65         * Makefile.in: Make objects depend on d10v_sim.h.
  66         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
  67         CFLAGS does not override host/target defines or SIM_CFLAGS.
  68         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
  69         (run): By default, the math library is not needed to be linked

  72         overridden.

  77         (gencode{,.o},d10v-opc.o): Split compilation into creating object
  78         and linking.  Instead of linking in libopcodes.a, just compile
  79         d10v-opc.o directly to handle canadian cross.
  80         (CSEARCH): Add opcodes directory.
  81
  82         * configure.in (--enable-sim-cflags): New switch to allow user to
  83         set the defaults.
