It is declared in . I guess you are suggesting: why not put the unwind code in the dynamic linker? In principle we could do that someday. In practice that would fix the ABI and API not merely the ABI of the unwind information, which is already fixed, but also the ABI and API of the unwinder. That might be desirable at some point, but for now I think it would be better to let the compiler continue own it. dl_iterate_phdr is provided by the dynamic linker. It is declared in .

I think I'm still missing some context.
