1627 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1628 (ins_type_counters): Counters for the various instruction types.
1629 ({left,right}_nops): Counters for the number of nops in each
1630 container.
1631 (d10v_debug): New variable to indicate whether debugging is turned
1632 on.
1633
1634 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1635 the input and output values can be traced, along with the
1636 instruction type. Make the -t option enable tracing.
1637 (all functions): Change printf calls to use the printf_filtered
1638 function in the callback table.
1639
1640 * interp.c (_leftright): New enumeration to say whether 2 short
1641 instructions are done left first or right first.
1642 (do_{long,2_short,parallel}): Indicate in the machine state which
1643 type of instruction this is. Count each of the types of
1644 instructions executed.
1645 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1646 flag is set.
1647 (sim_resume): Pass left/right indication to do_2_short.
1648 (all functions): Change printf calls to use the printf_filtered
1649 function in the callback table.
1650 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1651 sim_resume.
1652 (sim_info): Print out statistics on instructions.
1653 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1654 debugging.
1655 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1656 Only initialize the hash table the first time sim_open is called.
1657
1658 * Makefile.in: Make objects depend on d10v_sim.h.
1659 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1660 CFLAGS does not override host/target defines or SIM_CFLAGS.
1661 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1662 (run): By default, the math library is not needed to be linked
1663 in.
1664 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1665 overridden.
1666 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1667 makes.
1668 ({run,callback}.o): Provide explicit paths to their appropriate
1669 source directories.
1670 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1671 and linking. Instead of linking in libopcodes.a, just compile
1672 d10v-opc.o directly to handle canadian cross.
1673 (CSEARCH): Add opcodes directory.
1674
1675 * configure.in (--enable-sim-cflags): New switch to allow user to
1676 set the defaults.
1677 (CC_FOR_BUILD): Deal with canadian crosses.
1678 * configure: Regenerate.

1683 Fix #ifdef SYS_stat.

1687 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1688 Add trap 2 to be printf and trap 3 to be putchar.
