1643
1644 * simops.c (trace_output): Properly align accumulator output.
1645 (OP_3{0,2,4}00): Properly parenthesize test expression. Add error
1646 if shift count is too high.
1647 (OP_4E{00,02,04,20,22,40,42}): Make tests agree with book.
1648 (OP_4E09): Make cpfg properly trace the input flags.
1649 (op_types): Add OP_FLAG_OUTPUT.
1650 (trace_{input,output}): Support OP_FLAG_OUTPUT.
1651 (OP_31000000): This ld2w varient is a 16-bit memory reference, not
1652 an 8-bit memory reference instruction for tracing purposes.
1653 (OP_201): Addi needs to set the carry.
1654
1655Fri Sep 6 17:56:17 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1656
1657 * simops.c (OP_2600, OP_2601): Changed min and max comparisons
1658 to use signed register values.
1659

1661
1662 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1663 output.
1664 (_ins_type): New enumeration to specify which container an
1665 instruction is in, and whether it is part of a parallel operation.
1666 (_state): Add ins_type field.
1667 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1668 (ins_type_counters): Counters for the various instruction types.
1669 ({left,right}_nops): Counters for the number of nops in each
1670 container.
1671 (d10v_debug): New variable to indicate whether debugging is turned
1672 on.
1673
1674 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1675 the input and output values can be traced, along with the
1676 instruction type. Make the -t option enable tracing.
1677 (all functions): Change printf calls to use the printf_filtered
1678 function in the callback table.
1679
1680 * interp.c (_leftright): New enumeration to say whether 2 short
1681 instructions are done left first or right first.
1682 (do_{long,2_short,parallel}): Indicate in the machine state which
1683 type of instruction this is. Count each of the types of
1684 instructions executed.
1685 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1686 flag is set.
1687 (sim_resume): Pass left/right indication to do_2_short.
1688 (all functions): Change printf calls to use the printf_filtered
1689 function in the callback table.
1690 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1691 sim_resume.
1692 (sim_info): Print out statistics on instructions.
1693 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1694 debugging.
1695 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1696 Only initialize the hash table the first time sim_open is called.
1697
1698 * Makefile.in: Make objects depend on d10v_sim.h.
1699 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1700 CFLAGS does not override host/target defines or SIM_CFLAGS.
1701 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1702 (run): By default, the math library is not needed to be linked
1703 in.
1704 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1705 overridden.
1706 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1707 makes.
1708 ({run,callback}.o): Provide explicit paths to their appropriate
1709 source directories.
1710 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1711 and linking. Instead of linking in libopcodes.a, just compile
1712 d10v-opc.o directly to handle canadian cross.
1713 (CSEARCH): Add opcodes directory.
1714
1715 * configure.in (--enable-sim-cflags): New switch to allow user to
1716 set the defaults.
1717 (CC_FOR_BUILD): Deal with canadian crosses.
1718 * configure: Regenerate.

1723 Fix #ifdef SYS_stat.
1724

1726
1727 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1728 Add trap 2 to be printf and trap 3 to be putchar.
1729
