| 1507 | * Makefile.in: Make objects depend on d10v_sim.h. |
| 1508 | ({,SIM_}CFLAGS): Include configure dependent switches. Setting |
| 1509 | CFLAGS does not override host/target defines or SIM_CFLAGS. |
| 1510 | (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode. |
| 1511 | (run): By default, the math library is not needed to be linked |
| 1512 | in. |
| 1513 | ({BFD,LIBIBERTY}_LIB): Define as variables so they can be |
| 1514 | overridden. |
| 1515 | (VPATH): Don't set to anything but @srcdir@ to work with non-GNU |
| 1516 | makes. |
| 1517 | ({run,callback}.o): Provide explicit paths to their appropriate |
| 1518 | source directories. |
| 1519 | (gencode{,.o},d10v-opc.o): Split compilation into creating object |
| 1520 | and linking. Instead of linking in libopcodes.a, just compile |
| 1521 | d10v-opc.o directly to handle canadian cross. |
| 1522 | (CSEARCH): Add opcodes directory. |
| 1523 | |
| 1524 | * configure.in (--enable-sim-cflags): New switch to allow user to |
| 1525 | set the defaults. |
| 1526 | (CC_FOR_BUILD): Deal with canadian crosses. |
| 1527 | * configure: Regenerate. |
