1283
1284 * simops.c (trace_output): Properly align accumulator output.
1285 (OP_3{0,2,4}00): Properly parenthesize test expression. Add error
1286 if shift count is too high.
1287 (OP_4E{00,02,04,20,22,40,42}): Make tests agree with book.
1288 (OP_4E09): Make cpfg properly trace the input flags.
1289 (op_types): Add OP_FLAG_OUTPUT.
1290 (trace_{input,output}): Support OP_FLAG_OUTPUT.
1291 (OP_31000000): This ld2w varient is a 16-bit memory reference, not
1292 an 8-bit memory reference instruction for tracing purposes.
1293 (OP_201): Addi needs to set the carry.
1294
1295Fri Sep 6 17:56:17 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1296
1297 * simops.c (OP_2600, OP_2601): Changed min and max comparisons
1298 to use signed register values.

1301
1302 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1303 output.
1304 (_ins_type): New enumeration to specify which container an
1305 instruction is in, and whether it is part of a parallel operation.
1306 (_state): Add ins_type field.
1307 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1308 (ins_type_counters): Counters for the various instruction types.
1309 ({left,right}_nops): Counters for the number of nops in each
1310 container.
1311 (d10v_debug): New variable to indicate whether debugging is turned
1312 on.
1313
1314 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1315 the input and output values can be traced, along with the
1316 instruction type. Make the -t option enable tracing.
1317 (all functions): Change printf calls to use the printf_filtered
1318 function in the callback table.
1319
1320 * interp.c (_leftright): New enumeration to say whether 2 short
1321 instructions are done left first or right first.
1322 (do_{long,2_short,parallel}): Indicate in the machine state which
1323 type of instruction this is. Count each of the types of
1324 instructions executed.
1325 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1326 flag is set.
1327 (sim_resume): Pass left/right indication to do_2_short.
1328 (all functions): Change printf calls to use the printf_filtered
1329 function in the callback table.
1330 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1331 sim_resume.
1332 (sim_info): Print out statistics on instructions.
1333 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1334 debugging.
1335 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1336 Only initialize the hash table the first time sim_open is called.
1337
1338 * Makefile.in: Make objects depend on d10v_sim.h.
1339 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1340 CFLAGS does not override host/target defines or SIM_CFLAGS.
1341 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1342 (run): By default, the math library is not needed to be linked
1343 in.
1344 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1345 overridden.
1346 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1347 makes.
1348 ({run,callback}.o): Provide explicit paths to their appropriate
1349 source directories.
1350 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1351 and linking. Instead of linking in libopcodes.a, just compile
1352 d10v-opc.o directly to handle canadian cross.
1353 (CSEARCH): Add opcodes directory.
1354
1355 * configure.in (--enable-sim-cflags): New switch to allow user to
1356 set the defaults.

1366
1367 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1368 Add trap 2 to be printf and trap 3 to be putchar.
