1796
1797         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1798         the input and output values can be traced, along with the
1799         instruction type.  Make the -t option enable tracing.

1809         flag is set.

1821         * Makefile.in: Make objects depend on d10v_sim.h.
1822         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1823         CFLAGS does not override host/target defines or SIM_CFLAGS.
1824         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1825         (run): By default, the math library is not needed to be linked
1826         in.

1832         source directories.
1833         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1834         and linking.  Instead of linking in libopcodes.a, just compile
1835         d10v-opc.o directly to handle canadian cross.
1836         (CSEARCH): Add opcodes directory.
1837
1838         * configure.in (--enable-sim-cflags): New switch to allow user to
