1756
1757         * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1758         output.
1759         (_ins_type): New enumeration to specify which container an
1760         instruction is in, and whether it is part of a parallel operation.
1761         (_state): Add ins_type field.
1762         ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.

1765         container.

1767         on.
1768
1769         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1770         the input and output values can be traced, along with the
1771         instruction type.  Make the -t option enable tracing.
1772         (all functions): Change printf calls to use the printf_filtered
1773         function in the callback table.
1774
1775         * interp.c (_leftright): New enumeration to say whether 2 short
1776         instructions are done left first or right first.
1777         (do_{long,2_short,parallel}): Indicate in the machine state which
1778         type of instruction this is.  Count each of the types of
1779         instructions executed.
1780         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1781         flag is set.
1782         (sim_resume): Pass left/right indication to do_2_short.
1783         (all functions): Change printf calls to use the printf_filtered
1784         function in the callback table.
1785         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1786         sim_resume.
1787         (sim_info): Print out statistics on instructions.
1788         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1789         debugging.
1790         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1791         Only initialize the hash table the first time sim_open is called.
1792
1793         * Makefile.in: Make objects depend on d10v_sim.h.
1794         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1795         CFLAGS does not override host/target defines or SIM_CFLAGS.
1796         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1797         (run): By default, the math library is not needed to be linked
1798         in.
1799         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1800         overridden.
1801         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1802         makes.
1803         ({run,callback}.o): Provide explicit paths to their appropriate
1804         source directories.
1805         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1806         and linking.  Instead of linking in libopcodes.a, just compile
1807         d10v-opc.o directly to handle canadian cross.
1808         (CSEARCH): Add opcodes directory.
1809
1810         * configure.in (--enable-sim-cflags): New switch to allow user to
1811         set the defaults.
1812         (CC_FOR_BUILD): Deal with canadian crosses.
1813         * configure: Regenerate.
