1269 (_state): Add ins_type field.
1270 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1271 (ins_type_counters): Counters for the various instruction types.
1272 ({left,right}_nops): Counters for the number of nops in each
1273 container.
1274 (d10v_debug): New variable to indicate whether debugging is turned
1275 on.
1276
1277 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1278 the input and output values can be traced, along with the
1279 instruction type. Make the -t option enable tracing.
1280 (all functions): Change printf calls to use the printf_filtered
1281 function in the callback table.
1282
1283 * interp.c (_leftright): New enumeration to say whether 2 short
1284 instructions are done left first or right first.
1285 (do_{long,2_short,parallel}): Indicate in the machine state which
1286 type of instruction this is. Count each of the types of
1287 instructions executed.
1288 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1289 flag is set.
1290 (sim_resume): Pass left/right indication to do_2_short.
1291 (all functions): Change printf calls to use the printf_filtered
1292 function in the callback table.
1293 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1294 sim_resume.
1295 (sim_info): Print out statistics on instructions.
1296 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1297 debugging.
1298 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1299 Only initialize the hash table the first time sim_open is called.
1300
1301 * Makefile.in: Make objects depend on d10v_sim.h.
1302 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1303 CFLAGS does not override host/target defines or SIM_CFLAGS.
1304 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1305 (run): By default, the math library is not needed to be linked
1306 in.
1307 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1308 overridden.
1309 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1310 makes.
1311 ({run,callback}.o): Provide explicit paths to their appropriate
1312 source directories.
1313 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1314 and linking. Instead of linking in libopcodes.a, just compile
1315 d10v-opc.o directly to handle canadian cross.
1316 (CSEARCH): Add opcodes directory.
1317
1318 * configure.in (--enable-sim-cflags): New switch to allow user to
1319 set the defaults.
1320 (CC_FOR_BUILD): Deal with canadian crosses.
1321 * configure: Regenerate.

1325 * simops.c: Include correct syscall.h for d10v, not host's.
1326 Fix #ifdef SYS_stat.
1327

1329
1330 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1331 Add trap 2 to be printf and trap 3 to be putchar.
1332
