1747
1748 * simops.c (OP_2600, OP_2601): Changed min and max comparisons
1749 to use signed register values.
1750

1752
1753 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1754 output.
1755 (_ins_type): New enumeration to specify which container an
1756 instruction is in, and whether it is part of a parallel operation.
1757 (_state): Add ins_type field.
1758 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1759 (ins_type_counters): Counters for the various instruction types.
1760 ({left,right}_nops): Counters for the number of nops in each
1761 container.
1762 (d10v_debug): New variable to indicate whether debugging is turned
1763 on.
1764
1765 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1766 the input and output values can be traced, along with the
1767 instruction type. Make the -t option enable tracing.
1768 (all functions): Change printf calls to use the printf_filtered
1769 function in the callback table.
1770
1771 * interp.c (_leftright): New enumeration to say whether 2 short
1772 instructions are done left first or right first.
1773 (do_{long,2_short,parallel}): Indicate in the machine state which
1774 type of instruction this is. Count each of the types of
1775 instructions executed.
1776 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1777 flag is set.
1778 (sim_resume): Pass left/right indication to do_2_short.
1779 (all functions): Change printf calls to use the printf_filtered
1780 function in the callback table.
1781 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1782 sim_resume.
1783 (sim_info): Print out statistics on instructions.
1784 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1785 debugging.
1786 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1787 Only initialize the hash table the first time sim_open is called.
1788
1789 * Makefile.in: Make objects depend on d10v_sim.h.
1790 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1791 CFLAGS does not override host/target defines or SIM_CFLAGS.
1792 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1793 (run): By default, the math library is not needed to be linked
1794 in.
1795 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1796 overridden.
1797 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1798 makes.
1799 ({run,callback}.o): Provide explicit paths to their appropriate
1800 source directories.
1801 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1802 and linking. Instead of linking in libopcodes.a, just compile
1803 d10v-opc.o directly to handle canadian cross.
1804 (CSEARCH): Add opcodes directory.
1805
1806 * configure.in (--enable-sim-cflags): New switch to allow user to
1807 set the defaults.
1808 (CC_FOR_BUILD): Deal with canadian crosses.
1809 * configure: Regenerate.

1811 Wed Sep 04 04:45:34 1996 Mark Alexander <marka@cygnus.com>
1812
1813 * simops.c: Include correct syscall.h for d10v, not host's.
1814 Fix #ifdef SYS_stat.
1815
1816 Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1817
1818 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1819 Add trap 2 to be printf and trap 3 to be putchar.
1820
1821 Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com>
1822
1823 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1824 for low-level system calls.

1835
1836 Thu Aug 15 13:30:03 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1837
1838 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1839 DSP instructions. Added modulo addressing.
