1526 (sim_info): Print out statistics on instructions.
1527 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1529 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1530 Only initialize the hash table the first time sim_open is called.
1532 * Makefile.in: Make objects depend on d10v_sim.h.
1533 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1534 CFLAGS does not override host/target defines or SIM_CFLAGS.
1535 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1536 (run): By default, the math library is not needed to be linked
1538 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1540 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1542 ({run,callback}.o): Provide explicit paths to their appropriate
1544 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1545 and linking. Instead of linking in libopcodes.a, just compile
1546 d10v-opc.o directly to handle canadian cross.
1547 (CSEARCH): Add opcodes directory.
1549 * configure.in (--enable-sim-cflags): New switch to allow user to
1551 (CC_FOR_BUILD): Deal with canadian crosses.
1552 * configure: Regenerate.

1556 * simops.c: Include correct syscall.h for d10v, not host's.
1557 Fix #ifdef SYS_stat.
1559 Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1561 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1562 Add trap 2 to be printf and trap 3 to be putchar.

1567 for low-level system calls.
1569 Wed Aug 28 17:33:19 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1571 * Makefile.in, d10v_sim.h, interp.c: Fix byte-order problems.
1573 Mon Aug 26 18:30:28 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1575 * d10v_sim.h (SEXT32): Added.
1576 * interp.c: Commented out printfs.
