! In case anybody wonders why this code is same for both ABI.
! To start with it's not. Do note LDPTR below. But of course
! you must be wondering why the rest of it doesn't contain
! things like %hh, %hm and %lm. Well, those are needed only
! if OpenSSL library *itself* will become larger than 4GB,
! which is not going to happen any time soon.
