Last I know from discussions at Cauldron, I am responsible for working on fixing IFUNC related issues that prevent us from doing anything useful in an ifunc, including accessing vdso. It is on my list of things to do right after tunables.
Another option would be to get the complete implementation of memcmp etc. fom the vDSO, I think.
In the ARM context, there were also suggestions that we should support big/little asymmetric multi-processing. I hope we don't have to do this. It would seriously limit IFUNC selection and other microarchitecture-based optimizations.
Thanks, Florian
