1740         function in the callback table.
1741         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1742         sim_resume.
1743         (sim_info): Print out statistics on instructions.
1744         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1745         debugging.
1746         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1747         Only initialize the hash table the first time sim_open is called.
1748
1749         * Makefile.in: Make objects depend on d10v_sim.h.
1750         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1751         CFLAGS does not override host/target defines or SIM_CFLAGS.
1752         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1753         (run): By default, the math library is not needed to be linked
1754         in.
1755         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1756         overridden.
1757         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1758         makes.
1759         ({run,callback}.o): Provide explicit paths to their appropriate
1760         source directories.
1761         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1762         and linking.  Instead of linking in libopcodes.a, just compile
1763         d10v-opc.o directly to handle canadian cross.
1764         (CSEARCH): Add opcodes directory.
1765
1766         * configure.in (--enable-sim-cflags): New switch to allow user to
1767         set the defaults.
1768         (CC_FOR_BUILD): Deal with canadian crosses.
1769         * configure: Regenerate.

1778         * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
