1274 (OP_4E09): Make cpfg properly trace the input flags.
1275 (op_types): Add OP_FLAG_OUTPUT.
1276 (trace_{input,output}): Support OP_FLAG_OUTPUT.
1277 (OP_31000000): This ld2w varient is a 16-bit memory reference, not
1278 an 8-bit memory reference instruction for tracing purposes.
1279 (OP_201): Addi needs to set the carry.
1280
1281Fri Sep 6 17:56:17 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1282
1283 * simops.c (OP_2600, OP_2601): Changed min and max comparisons
1284 to use signed register values.
1285

1287
1288 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1289 output.
1290 (_ins_type): New enumeration to specify which container an
1291 instruction is in, and whether it is part of a parallel operation.
1292 (_state): Add ins_type field.
1293 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1294 (ins_type_counters): Counters for the various instruction types.
1295 ({left,right}_nops): Counters for the number of nops in each
1296 container.
1297 (d10v_debug): New variable to indicate whether debugging is turned
1298 on.
1299
1300 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1301 the input and output values can be traced, along with the
1302 instruction type. Make the -t option enable tracing.
1303 (all functions): Change printf calls to use the printf_filtered
1304 function in the callback table.
1305
1306 * interp.c (_leftright): New enumeration to say whether 2 short
1307 instructions are done left first or right first.
1308 (do_{long,2_short,parallel}): Indicate in the machine state which
1309 type of instruction this is. Count each of the types of
1310 instructions executed.
1311 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1312 flag is set.
1313 (sim_resume): Pass left/right indication to do_2_short.
1314 (all functions): Change printf calls to use the printf_filtered
1315 function in the callback table.
1316 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1317 sim_resume.
1318 (sim_info): Print out statistics on instructions.
1319 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1320 debugging.
1321 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1322 Only initialize the hash table the first time sim_open is called.
1323
1324 * Makefile.in: Make objects depend on d10v_sim.h.
1325 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1326 CFLAGS does not override host/target defines or SIM_CFLAGS.
1327 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1328 (run): By default, the math library is not needed to be linked
1329 in.
1330 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1331 overridden.
1332 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1333 makes.
1334 ({run,callback}.o): Provide explicit paths to their appropriate
1335 source directories.
1336 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1337 and linking. Instead of linking in libopcodes.a, just compile
1338 d10v-opc.o directly to handle canadian cross.
1339 (CSEARCH): Add opcodes directory.
1340
1341 * configure.in (--enable-sim-cflags): New switch to allow user to
1342 set the defaults.
1343 (CC_FOR_BUILD): Deal with canadian crosses.
1344 * configure: Regenerate.

1352
1353 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1354 Add trap 2 to be printf and trap 3 to be putchar.
1355
1356Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com>
1357
1358 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1359 for low-level system calls.

1373 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1374 DSP instructions. Added modulo addressing.
