1270 (all functions): Change printf calls to use the printf_filtered
1271 function in the callback table.
1272 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1273 sim_resume.
1274 (sim_info): Print out statistics on instructions.
1275 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1276 debugging.
1277 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1278 Only initialize the hash table the first time sim_open is called.
1279
1280 * Makefile.in: Make objects depend on d10v_sim.h.
1281 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1282 CFLAGS does not override host/target defines or SIM_CFLAGS.
1283 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1284 (run): By default, the math library is not needed to be linked
1285 in.
1286 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1287 overridden.
1288 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1289 makes.
1290 ({run,callback}.o): Provide explicit paths to their appropriate
1291 source directories.
1292 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1293 and linking. Instead of linking in libopcodes.a, just compile
1294 d10v-opc.o directly to handle canadian cross.
1295 (CSEARCH): Add opcodes directory.
1296
1297 * configure.in (--enable-sim-cflags): New switch to allow user to
1298 set the defaults.
1299 (CC_FOR_BUILD): Deal with canadian crosses.
1300 * configure: Regenerate.
