o Relocations generated w.r.t absolute symbols are not processed as by definition, absolute symbols are not to be relocated. Explicitly warn user about absolutions relocations present at compile time. o These relocations get introduced either due to linker optimizations or some programming oversights. o Also create a list of symbols which have been audited to be safe and don't emit warnings for these.
