1328 (OP_4E09): Make cpfg properly trace the input flags.

1331 (OP_31000000): This ld2w varient is a 16-bit memory reference, not
1332 an 8-bit memory reference instruction for tracing purposes.
1333 (OP_201): Addi needs to set the carry.
1334
1335 Fri Sep 6 17:56:17 1996 Martin M. Hunt <hunt@pizza.cygnus.com>

1341
1342 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1343 output.
1344 (_ins_type): New enumeration to specify which container an
1345 instruction is in, and whether it is part of a parallel operation.
1346 (_state): Add ins_type field.
1347 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1348 (ins_type_counters): Counters for the various instruction types.
1349 ({left,right}_nops): Counters for the number of nops in each
1350 container.
1351 (d10v_debug): New variable to indicate whether debugging is turned
1352 on.
1353
1354 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1355 the input and output values can be traced, along with the
1356 instruction type. Make the -t option enable tracing.
1357 (all functions): Change printf calls to use the printf_filtered
1358 function in the callback table.
1359
1360 * interp.c (_leftright): New enumeration to say whether 2 short
1361 instructions are done left first or right first.
1362 (do_{long,2_short,parallel}): Indicate in the machine state which
1363 type of instruction this is. Count each of the types of
1364 instructions executed.
1365 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1366 flag is set.
1367 (sim_resume): Pass left/right indication to do_2_short.
1368 (all functions): Change printf calls to use the printf_filtered
1369 function in the callback table.
1370 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1371 sim_resume.
1372 (sim_info): Print out statistics on instructions.
1373 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1374 debugging.
1375 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1376 Only initialize the hash table the first time sim_open is called.
1377
1378 * Makefile.in: Make objects depend on d10v_sim.h.
1379 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1380 CFLAGS does not override host/target defines or SIM_CFLAGS.
1381 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1382 (run): By default, the math library is not needed to be linked
1383 in.
1384 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1385 overridden.
1386 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1387 makes.
1388 ({run,callback}.o): Provide explicit paths to their appropriate
1389 source directories.
1390 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1391 and linking. Instead of linking in libopcodes.a, just compile
1392 d10v-opc.o directly to handle canadian cross.
1393 (CSEARCH): Add opcodes directory.
1394
1395 * configure.in (--enable-sim-cflags): New switch to allow user to

1406
1407 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1408 Add trap 2 to be printf and trap 3 to be putchar.

1427 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1428 DSP instructions. Added modulo addressing.
