   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.

   8
   9         * simops.c (OP_2600, OP_2601): Changed min and max comparisons
  10         to use signed register values.
  11
  12 Wed Sep  4 11:35:17 1996  Michael Meissner  <meissner@tiktok.cygnus.com>
  13
  14         * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
  15         output.
  16         (_ins_type): New enumeration to specify which container an
  17         instruction is in, and whether it is part of a parallel operation.
  18         (_state): Add ins_type field.
  19         ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
  20         (ins_type_counters): Counters for the various instruction types.
  21         ({left,right}_nops): Counters for the number of nops in each
  22         container.
  23         (d10v_debug): New variable to indicate whether debugging is turned
  24         on.
  25
  26         * simops.c: (all functions): Change all #ifdef DEBUG code so that
  27         the input and output values can be traced, along with the
  28         instruction type.  Make the -t option enable tracing.
  29         (all functions): Change printf calls to use the printf_filtered
  30         function in the callback table.
  31
  32         * interp.c (_leftright): New enumeration to say whether 2 short
  33         instructions are done left first or right first.
  34         (do_{long,2_short,parallel}): Indicate in the machine state which
  35         type of instruction this is.  Count each of the types of
  36         instructions executed.
  37         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
  38         flag is set.
  39         (sim_resume): Pass left/right indication to do_2_short.
  40         (all functions): Change printf calls to use the printf_filtered
  41         function in the callback table.
  42         (sim_trace): Turn on debug flag if DEBUG was defined, and call
  43         sim_resume.
  44         (sim_info): Print out statistics on instructions.
  45         (sim_{trace,create_inferior}): Eliminate extraneous output unless
  46         debugging.
  47         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
  48         Only initialize the hash table the first time sim_open is called.
  49
  50         * Makefile.in: Make objects depend on d10v_sim.h.
  51         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
  52         CFLAGS does not override host/target defines or SIM_CFLAGS.
  53         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
  54         (run): By default, the math library is not needed to be linked
  55         in.
  56         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
  57         overridden.
  58         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
  59         makes.
  60         ({run,callback}.o): Provide explicit paths to their appropriate
  61         source directories.
  62         (gencode{,.o},d10v-opc.o): Split compilation into creating object
  63         and linking.  Instead of linking in libopcodes.a, just compile
  64         d10v-opc.o directly to handle canadian cross.
  65         (CSEARCH): Add opcodes directory.
  66
  67         * configure.in (--enable-sim-cflags): New switch to allow user to
  68         set the defaults.
  69         (CC_FOR_BUILD): Deal with canadian crosses.
  70         * configure: Regenerate.
