1284 (OP_4E09): Make cpfg properly trace the input flags.

1287 (OP_31000000): This ld2w varient is a 16-bit memory reference, not
1288 an 8-bit memory reference instruction for tracing purposes.
1289 (OP_201): Addi needs to set the carry.
1290
1291Fri Sep 6 17:56:17 1996 Martin M. Hunt <hunt@pizza.cygnus.com>

1297
1298 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1299 output.
1300 (_ins_type): New enumeration to specify which container an
1301 instruction is in, and whether it is part of a parallel operation.
1302 (_state): Add ins_type field.
1303 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1304 (ins_type_counters): Counters for the various instruction types.
1305 ({left,right}_nops): Counters for the number of nops in each
1306 container.
1307 (d10v_debug): New variable to indicate whether debugging is turned
1308 on.
1309
1310 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1311 the input and output values can be traced, along with the
1312 instruction type. Make the -t option enable tracing.
1313 (all functions): Change printf calls to use the printf_filtered
1314 function in the callback table.
1315
1316 * interp.c (_leftright): New enumeration to say whether 2 short
1317 instructions are done left first or right first.
1318 (do_{long,2_short,parallel}): Indicate in the machine state which
1319 type of instruction this is. Count each of the types of
1320 instructions executed.
1321 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1322 flag is set.
1323 (sim_resume): Pass left/right indication to do_2_short.
1324 (all functions): Change printf calls to use the printf_filtered
1325 function in the callback table.
1326 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1327 sim_resume.
1328 (sim_info): Print out statistics on instructions.
1329 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1330 debugging.
1331 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1332 Only initialize the hash table the first time sim_open is called.
1333
1334 * Makefile.in: Make objects depend on d10v_sim.h.
1335 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1336 CFLAGS does not override host/target defines or SIM_CFLAGS.
1337 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1338 (run): By default, the math library is not needed to be linked
1339 in.
1340 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1341 overridden.
1342 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1343 makes.
1344 ({run,callback}.o): Provide explicit paths to their appropriate
1345 source directories.
1346 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1347 and linking. Instead of linking in libopcodes.a, just compile
1348 d10v-opc.o directly to handle canadian cross.

1350
1351 * configure.in (--enable-sim-cflags): New switch to allow user to

1362
1363 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1364 Add trap 2 to be printf and trap 3 to be putchar.

1383 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1384 DSP instructions. Added modulo addressing.
