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

1315
1316 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1317 Add trap 2 to be printf and trap 3 to be putchar.
