This creates weird dependency * issue: * * 1. Using A.ld to create a linker script A.cmd. * 2. Using A.cmd to generate A_prebuilt.elf. * 3. Using A_prebuilt.elf to create B.ld. * 4. Creating B.cmd with B.ld. * 5. Creating B_prebuilt.elf using B.cmd. * * Since the dependency list of A.cmd contains both * A.ld and B.ld, when make is invoked again, B.ld * is newer than A.cmd so everything from this point on * gets rebuilt. In order to break this cycle, this * hackish needs to be used since CMake does not parse * macros, and thus these will not appear in * the dependency list. The dependencies should then be * put in CMakeLists.txt instead. * * Note: Ninja generator does not suffer from this issue. */ #ifdef LINKER_APP_SMEM_UNALIGNED #define APP_SMEM_LD <app_smem_unaligned.ld> #else #define APP_SMEM_LD <app_smem_aligned.ld> #endif #include APP_SMEM_LD #undef APP_SMEM_LD |
