The DEBUG macro is not part of any compiler standards (differently from NDEBUG, which elides assertions). It is only meant to differentiate gem5.debug from .fast and .opt builds. gem5 developers have used it to insert helper code that is supposed to aid the debugging process in case anything goes wrong. This generic name is likely to clash with other libraries linked with gem5. This is the case of DRAMSim as an example. Rather than using undef tricks, we just inject a GEM5_DEBUG macro for gem5.debug builds.
