1758
1759         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1760         the input and output values can be traced, along with the
1761         instruction type.  Make the -t option enable tracing.
1762         (all functions): Change printf calls to use the printf_filtered
1763         function in the callback table.

1768         type of instruction this is.  Count each of the types of
1769         instructions executed.
1770         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1771         flag is set.
1772         (sim_resume): Pass left/right indication to do_2_short.

1774         function in the callback table.
1775         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1776         sim_resume.
1777         (sim_info): Print out statistics on instructions.
1778         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1779         debugging.
1780         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1781         Only initialize the hash table the first time sim_open is called.
1782
1783         * Makefile.in: Make objects depend on d10v_sim.h.
1784         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1785         CFLAGS does not override host/target defines or SIM_CFLAGS.
1786         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1787         (run): By default, the math library is not needed to be linked
1788         in.
1789         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1790         overridden.
1791         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1792         makes.
1793         ({run,callback}.o): Provide explicit paths to their appropriate
1794         source directories.
1795         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1796         and linking.  Instead of linking in libopcodes.a, just compile
1797         d10v-opc.o directly to handle canadian cross.
1798         (CSEARCH): Add opcodes directory.
1799
1800         * configure.in (--enable-sim-cflags): New switch to allow user to
1801         set the defaults.
1802         (CC_FOR_BUILD): Deal with canadian crosses.
1803         * configure: Regenerate.
