1634 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1635 output.
1636 (_ins_type): New enumeration to specify which container an
1637 instruction is in, and whether it is part of a parallel operation.
1638 (_state): Add ins_type field.
1639 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1640 (ins_type_counters): Counters for the various instruction types.
1641 ({left,right}_nops): Counters for the number of nops in each
1642 container.
1643 (d10v_debug): New variable to indicate whether debugging is turned
1644 on.
1645
1646 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1647 the input and output values can be traced, along with the
1648 instruction type. Make the -t option enable tracing.
1649 (all functions): Change printf calls to use the printf_filtered
1650 function in the callback table.
1651
1652 * interp.c (_leftright): New enumeration to say whether 2 short
1653 instructions are done left first or right first.
1654 (do_{long,2_short,parallel}): Indicate in the machine state which
1655 type of instruction this is. Count each of the types of
1656 instructions executed.
1657 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1658 flag is set.
1659 (sim_resume): Pass left/right indication to do_2_short.
1660 (all functions): Change printf calls to use the printf_filtered
1661 function in the callback table.
1662 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1663 sim_resume.
1664 (sim_info): Print out statistics on instructions.
1665 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1666 debugging.
1667 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1668 Only initialize the hash table the first time sim_open is called.
1669
1670 * Makefile.in: Make objects depend on d10v_sim.h.
1671 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1672 CFLAGS does not override host/target defines or SIM_CFLAGS.
1673 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1674 (run): By default, the math library is not needed to be linked
1675 in.
1676 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1677 overridden.
1678 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1679 makes.
1680 ({run,callback}.o): Provide explicit paths to their appropriate
1681 source directories.
1682 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1683 and linking. Instead of linking in libopcodes.a, just compile
1684 d10v-opc.o directly to handle canadian cross.
1685 (CSEARCH): Add opcodes directory.
1686
1687 * configure.in (--enable-sim-cflags): New switch to allow user to
1688 set the defaults.
1689 (CC_FOR_BUILD): Deal with canadian crosses.
1690 * configure: Regenerate.
1691

1693
1694 * simops.c: Include correct syscall.h for d10v, not host's.
1695 Fix #ifdef SYS_stat.
1696
1697Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1698
1699 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1700 Add trap 2 to be printf and trap 3 to be putchar.
1701

1703
1704 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1705 for low-level system calls.
