 337         debugging.
 338         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
 339         Only initialize the hash table the first time sim_open is called.
 340
 341         * Makefile.in: Make objects depend on d10v_sim.h.
 342         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
 343         CFLAGS does not override host/target defines or SIM_CFLAGS.
 344         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
 345         (run): By default, the math library is not needed to be linked
 346         in.
 347         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
 348         overridden.
 349         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
 350         makes.
 351         ({run,callback}.o): Provide explicit paths to their appropriate
 352         source directories.
 353         (gencode{,.o},d10v-opc.o): Split compilation into creating object
 354         and linking.  Instead of linking in libopcodes.a, just compile
 355         d10v-opc.o directly to handle canadian cross.
 356         (CSEARCH): Add opcodes directory.
 357
 358         * configure.in (--enable-sim-cflags): New switch to allow user to
 359         set the defaults.
 360         (CC_FOR_BUILD): Deal with canadian crosses.
 361         * configure: Regenerate.

 369
 370         * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
 371         Add trap 2 to be printf and trap 3 to be putchar.
