1745         instructions are done left first or right first.
1746         (do_{long,2_short,parallel}): Indicate in the machine state which
1747         type of instruction this is.  Count each of the types of
1748         instructions executed.
1749         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1750         flag is set.
1751         (sim_resume): Pass left/right indication to do_2_short.
1752         (all functions): Change printf calls to use the printf_filtered
1753         function in the callback table.
1754         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1755         sim_resume.

1763         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1764         CFLAGS does not override host/target defines or SIM_CFLAGS.

1766         (run): By default, the math library is not needed to be linked
1767         in.
1768         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1769         overridden.
1770         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1771         makes.

1773         source directories.
1774         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1775         and linking.  Instead of linking in libopcodes.a, just compile
1776         d10v-opc.o directly to handle canadian cross.
1777         (CSEARCH): Add opcodes directory.
1778
1779         * configure.in (--enable-sim-cflags): New switch to allow user to
1780         set the defaults.
