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