If this is not passed in the symbol table to the linker, why is it in the DefinedAtom ? > In mach-o it *is* passed on to the linker by the compiler. It is the N_NO_DEAD_STRIP bit in the n_desc field of the nlist struct. Are you saying that that information is not recorded in ELF .o files? On ELF x86_64, I dont see the information being passed.
