1632 * Makefile.in: Make objects depend on d10v_sim.h.
1633 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1634 CFLAGS does not override host/target defines or SIM_CFLAGS.
1635 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1636 (run): By default, the math library is not needed to be linked
1637 in.
1638 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1639 overridden.
1640 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1641 makes.
1642 ({run,callback}.o): Provide explicit paths to their appropriate
1643 source directories.
1644 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1645 and linking. Instead of linking in libopcodes.a, just compile
1646 d10v-opc.o directly to handle canadian cross.
1647 (CSEARCH): Add opcodes directory.
1648
1649 * configure.in (--enable-sim-cflags): New switch to allow user to
1650 set the defaults.
1651 (CC_FOR_BUILD): Deal with canadian crosses.
1652 * configure: Regenerate.
