1631 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1632 debugging.
1633 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1634 Only initialize the hash table the first time sim_open is called.
1635
1636 * Makefile.in: Make objects depend on d10v_sim.h.
1637 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1638 CFLAGS does not override host/target defines or SIM_CFLAGS.
1639 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1640 (run): By default, the math library is not needed to be linked
1641 in.
1642 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1643 overridden.
1644 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1645 makes.
1646 ({run,callback}.o): Provide explicit paths to their appropriate
1647 source directories.
1648 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1649 and linking. Instead of linking in libopcodes.a, just compile
1650 d10v-opc.o directly to handle canadian cross.
1651 (CSEARCH): Add opcodes directory.
1652
1653 * configure.in (--enable-sim-cflags): New switch to allow user to
1654 set the defaults.
1655 (CC_FOR_BUILD): Deal with canadian crosses.
1656 * configure: Regenerate.
