1749         instructions are done left first or right first.
1750         (do_{long,2_short,parallel}): Indicate in the machine state which
1751         type of instruction this is.  Count each of the types of
1752         instructions executed.
1753         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1754         flag is set.
1755         (sim_resume): Pass left/right indication to do_2_short.
1756         (all functions): Change printf calls to use the printf_filtered
1757         function in the callback table.
1758         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1759         sim_resume.
1760         (sim_info): Print out statistics on instructions.

1762         debugging.

1767         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1768         CFLAGS does not override host/target defines or SIM_CFLAGS.
1769         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1770         (run): By default, the math library is not needed to be linked
1771         in.
1772         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1773         overridden.
1774         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1775         makes.
1776         ({run,callback}.o): Provide explicit paths to their appropriate
1777         source directories.
1778         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1779         and linking.  Instead of linking in libopcodes.a, just compile
1780         d10v-opc.o directly to handle canadian cross.
1781         (CSEARCH): Add opcodes directory.
1782
1783         * configure.in (--enable-sim-cflags): New switch to allow user to
1784         set the defaults.
1785         (CC_FOR_BUILD): Deal with canadian crosses.
