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

  60         function in the callback table.

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

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

  76         overridden.
  77         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU

  81         (gencode{,.o},d10v-opc.o): Split compilation into creating object
  82         and linking.  Instead of linking in libopcodes.a, just compile
  83         d10v-opc.o directly to handle canadian cross.
  84         (CSEARCH): Add opcodes directory.
  85
  86         * configure.in (--enable-sim-cflags): New switch to allow user to
  87         set the defaults.
