1741         (do_{long,2_short,parallel}): Indicate in the machine state which
1742         type of instruction this is.  Count each of the types of
1743         instructions executed.
1744         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1745         flag is set.
1746         (sim_resume): Pass left/right indication to do_2_short.
1747         (all functions): Change printf calls to use the printf_filtered
1748         function in the callback table.
1749         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1750         sim_resume.
1751         (sim_info): Print out statistics on instructions.
1752         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1753         debugging.
1754         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1755         Only initialize the hash table the first time sim_open is called.

1757         * Makefile.in: Make objects depend on d10v_sim.h.
1758         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1759         CFLAGS does not override host/target defines or SIM_CFLAGS.
1760         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1761         (run): By default, the math library is not needed to be linked
1762         in.
1763         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1764         overridden.
1765         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1766         makes.
1767         ({run,callback}.o): Provide explicit paths to their appropriate
1768         source directories.
1769         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1770         and linking.  Instead of linking in libopcodes.a, just compile
1771         d10v-opc.o directly to handle canadian cross.
1772         (CSEARCH): Add opcodes directory.
1773
1774         * configure.in (--enable-sim-cflags): New switch to allow user to
1775         set the defaults.
1776         (CC_FOR_BUILD): Deal with canadian crosses.
1777         * configure: Regenerate.
