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

1317Wed Sep 04 04:45:34 1996 Mark Alexander <marka@cygnus.com>
1318
1319 * simops.c: Include correct syscall.h for d10v, not host's.
1320 Fix #ifdef SYS_stat.
1321
1322Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1323
1324 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1325 Add trap 2 to be printf and trap 3 to be putchar.
1326
1327Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com>
1328
1329 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1330 for low-level system calls.
1331

1337
1338 * d10v_sim.h (SEXT32): Added.
1339 * interp.c: Commented out printfs.
1340 * simops.c: Fixed error in sb and st2w.
1341

1343
1344 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1345 DSP instructions. Added modulo addressing.
