   3         * simops.c (trace_output): Properly align accumulator output.
   4         (OP_3{0,2,4}00): Properly parenthesize test expression.  Add error
   5         if shift count is too high.

   9
  10         * simops.c (OP_2600, OP_2601): Changed min and max comparisons
  11         to use signed register values.

  13 Wed Sep  4 11:35:17 1996  Michael Meissner  <meissner@tiktok.cygnus.com>
  14
  15         * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
  16         output.
  17         (_ins_type): New enumeration to specify which container an
  18         instruction is in, and whether it is part of a parallel operation.
  19         (_state): Add ins_type field.
  20         ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
  21         (ins_type_counters): Counters for the various instruction types.
  22         ({left,right}_nops): Counters for the number of nops in each
  23         container.
  24         (d10v_debug): New variable to indicate whether debugging is turned
  25         on.
  26
  27         * simops.c: (all functions): Change all #ifdef DEBUG code so that
  28         the input and output values can be traced, along with the
  29         instruction type.  Make the -t option enable tracing.
  30         (all functions): Change printf calls to use the printf_filtered
  31         function in the callback table.
  32
  33         * interp.c (_leftright): New enumeration to say whether 2 short
  34         instructions are done left first or right first.
  35         (do_{long,2_short,parallel}): Indicate in the machine state which
  36         type of instruction this is.  Count each of the types of
  37         instructions executed.
  38         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
  39         flag is set.
  40         (sim_resume): Pass left/right indication to do_2_short.
  41         (all functions): Change printf calls to use the printf_filtered
  42         function in the callback table.
  43         (sim_trace): Turn on debug flag if DEBUG was defined, and call
  44         sim_resume.
  45         (sim_info): Print out statistics on instructions.
  46         (sim_{trace,create_inferior}): Eliminate extraneous output unless
  47         debugging.
  48         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
  49         Only initialize the hash table the first time sim_open is called.
  50
  51         * Makefile.in: Make objects depend on d10v_sim.h.
  52         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
  53         CFLAGS does not override host/target defines or SIM_CFLAGS.
  54         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
  55         (run): By default, the math library is not needed to be linked
  56         in.
  57         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
  58         overridden.
  59         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
  60         makes.
  61         ({run,callback}.o): Provide explicit paths to their appropriate
  62         source directories.
  63         (gencode{,.o},d10v-opc.o): Split compilation into creating object
  64         and linking.  Instead of linking in libopcodes.a, just compile
  65         d10v-opc.o directly to handle canadian cross.
  66         (CSEARCH): Add opcodes directory.
  67
  68         * configure.in (--enable-sim-cflags): New switch to allow user to
  69         set the defaults.
  70         (CC_FOR_BUILD): Deal with canadian crosses.
  71         * configure: Regenerate.
