1744         on.
1745
1746         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1747         the input and output values can be traced, along with the
1748         instruction type.  Make the -t option enable tracing.
1749         (all functions): Change printf calls to use the printf_filtered
1750         function in the callback table.
1751
1752         * interp.c (_leftright): New enumeration to say whether 2 short
1753         instructions are done left first or right first.
1754         (do_{long,2_short,parallel}): Indicate in the machine state which
1755         type of instruction this is.  Count each of the types of
1756         instructions executed.
1757         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1758         flag is set.
1759         (sim_resume): Pass left/right indication to do_2_short.
1760         (all functions): Change printf calls to use the printf_filtered
1761         function in the callback table.
1762         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1763         sim_resume.
1764         (sim_info): Print out statistics on instructions.
1765         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1766         debugging.
1767         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1768         Only initialize the hash table the first time sim_open is called.
1769
1770         * Makefile.in: Make objects depend on d10v_sim.h.
1771         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1772         CFLAGS does not override host/target defines or SIM_CFLAGS.
1773         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1774         (run): By default, the math library is not needed to be linked
1775         in.
1776         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1777         overridden.
1778         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1779         makes.
1780         ({run,callback}.o): Provide explicit paths to their appropriate
1781         source directories.
1782         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1783         and linking.  Instead of linking in libopcodes.a, just compile
1784         d10v-opc.o directly to handle canadian cross.
1785         (CSEARCH): Add opcodes directory.
1786
1787         * configure.in (--enable-sim-cflags): New switch to allow user to
1788         set the defaults.
1789         (CC_FOR_BUILD): Deal with canadian crosses.
1790         * configure: Regenerate.

1793
1794         * simops.c: Include correct syscall.h for d10v, not host's.
1795         Fix #ifdef SYS_stat.

1798
1799         * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1800         Add trap 2 to be printf and trap 3 to be putchar.
