1736         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1737         debugging.
1738         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1739         Only initialize the hash table the first time sim_open is called.
1740
1741         * Makefile.in: Make objects depend on d10v_sim.h.
1742         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1743         CFLAGS does not override host/target defines or SIM_CFLAGS.
1744         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1745         (run): By default, the math library is not needed to be linked
1746         in.
1747         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1748         overridden.
1749         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1750         makes.
1751         ({run,callback}.o): Provide explicit paths to their appropriate
1752         source directories.
1753         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1754         and linking.  Instead of linking in libopcodes.a, just compile
1755         d10v-opc.o directly to handle canadian cross.
1756         (CSEARCH): Add opcodes directory.
1757
1758         * configure.in (--enable-sim-cflags): New switch to allow user to
1759         set the defaults.
1760         (CC_FOR_BUILD): Deal with canadian crosses.
1761         * configure: Regenerate.

1767
1768 Tue Sep  3 14:00:04 1996  Michael Meissner  <meissner@tiktok.cygnus.com>
1769
1770         * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1771         Add trap 2 to be printf and trap 3 to be putchar.
