1627
1628 * Makefile.in: Make objects depend on d10v_sim.h.
1629 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1630 CFLAGS does not override host/target defines or SIM_CFLAGS.
1631 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1632 (run): By default, the math library is not needed to be linked
1633 in.
1634 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1635 overridden.
1636 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1637 makes.
1638 ({run,callback}.o): Provide explicit paths to their appropriate
1639 source directories.
1640 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1641 and linking. Instead of linking in libopcodes.a, just compile
1642 d10v-opc.o directly to handle canadian cross.
1643 (CSEARCH): Add opcodes directory.
1644
1645 * configure.in (--enable-sim-cflags): New switch to allow user to
1646 set the defaults.
1647 (CC_FOR_BUILD): Deal with canadian crosses.
1648 * configure: Regenerate.
