1485 | * Makefile.in: Make objects depend on d10v_sim.h. | |
1486 | ({,SIM_}CFLAGS): Include configure dependent switches. Setting | |
1487 | CFLAGS does not override host/target defines or SIM_CFLAGS. | |
1488 | (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode. | |
1489 | (run): By default, the math library is not needed to be linked | |
1490 | in. | |
1491 | ({BFD,LIBIBERTY}_LIB): Define as variables so they can be | |
1492 | overridden. | |
1493 | (VPATH): Don't set to anything but @srcdir@ to work with non-GNU | |
1494 | makes. | |
1495 | ({run,callback}.o): Provide explicit paths to their appropriate | |
1496 | source directories. | |
1497 | (gencode{,.o},d10v-opc.o): Split compilation into creating object | |
1498 | and linking. Instead of linking in libopcodes.a, just compile | |
1499 | d10v-opc.o directly to handle canadian cross. | |
1500 | (CSEARCH): Add opcodes directory. | |
1501 | ||
1502 | * configure.in (--enable-sim-cflags): New switch to allow user to | |
1503 | set the defaults. | |
1504 | (CC_FOR_BUILD): Deal with canadian crosses. | |
1505 | * configure: Regenerate. | |
