1629 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1630 the input and output values can be traced, along with the
1631 instruction type. Make the -t option enable tracing.
1632 (all functions): Change printf calls to use the printf_filtered
1633 function in the callback table.
1634
1635 * interp.c (_leftright): New enumeration to say whether 2 short
1636 instructions are done left first or right first.
1637 (do_{long,2_short,parallel}): Indicate in the machine state which
1638 type of instruction this is. Count each of the types of
1639 instructions executed.
1640 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1641 flag is set.
1642 (sim_resume): Pass left/right indication to do_2_short.
1643 (all functions): Change printf calls to use the printf_filtered
1644 function in the callback table.
1645 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1646 sim_resume.
1647 (sim_info): Print out statistics on instructions.
1648 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1649 debugging.
1650 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1651 Only initialize the hash table the first time sim_open is called.
1652
1653 * Makefile.in: Make objects depend on d10v_sim.h.
1654 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1655 CFLAGS does not override host/target defines or SIM_CFLAGS.
1656 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1657 (run): By default, the math library is not needed to be linked
1658 in.
1659 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1660 overridden.
1661 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1662 makes.
1663 ({run,callback}.o): Provide explicit paths to their appropriate
1664 source directories.
1665 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1666 and linking. Instead of linking in libopcodes.a, just compile
1667 d10v-opc.o directly to handle canadian cross.
1668 (CSEARCH): Add opcodes directory.
1669
1670 * configure.in (--enable-sim-cflags): New switch to allow user to
1671 set the defaults.
1672 (CC_FOR_BUILD): Deal with canadian crosses.
1673 * configure: Regenerate.

1677 * simops.c: Include correct syscall.h for d10v, not host's.
1678 Fix #ifdef SYS_stat.

1681
1682 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1683 Add trap 2 to be printf and trap 3 to be putchar.
