1497 * Makefile.in: Make objects depend on d10v_sim.h.
1498 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1499 CFLAGS does not override host/target defines or SIM_CFLAGS.
1500 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1501 (run): By default, the math library is not needed to be linked
1503 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1505 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1507 ({run,callback}.o): Provide explicit paths to their appropriate
1509 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1510 and linking. Instead of linking in libopcodes.a, just compile
1511 d10v-opc.o directly to handle canadian cross.
1512 (CSEARCH): Add opcodes directory.
1514 * configure.in (--enable-sim-cflags): New switch to allow user to
1516 (CC_FOR_BUILD): Deal with canadian crosses.
1517 * configure: Regenerate.
1521 * simops.c: Include correct syscall.h for d10v, not host's.
1522 Fix #ifdef SYS_stat.
1526 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1527 Add trap 2 to be printf and trap 3 to be putchar.
1531 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1532 for low-level system calls.
1536 * Makefile.in, d10v_sim.h, interp.c: Fix byte-order problems.
1540 * d10v_sim.h (SEXT32): Added.
1541 * interp.c: Commented out printfs.
1542 * simops.c: Fixed error in sb and st2w.
1546 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1547 DSP instructions. Added modulo addressing.
1551 * Makefile.in, d10v_sim.h, interp.c, simops.c: Snapshot.
1555 * d10v_sim.h, simops.c: Snapshot.
1559 * ChangeLog, Makefile.in, configure, configure.in, d10v_sim.h,
1560 gencode.c, interp.c, simops.c: Created.
