Re: Proposal for STT_GNU_IFUNC and R_*_IRELATIVE


To be a full description, it should say something about the ABI of the
entry-point that returns the function pointer.  Is it "the prevailing
normal ABI" for a function of no arguments returning a pointer to function?
i.e., with whatever call-clobbered registers et al that generically entails.
Or is it a special-case ABI to be defined precisely in the
processor-specific spec?  However much or little the specification of the
ELF feature per se wants to say about this, it should be explicit about
what it does or doesn't specify for it.


Thanks,
Roland
