Recently I have discovered Function Multiversioning (FMV) which is being used in Clear Linux.

It would be really nice to implement FMV as part of EB as away to avoid having to compile for each microarchitecture and also to save space.

How feasible do you think it is?

Victor Rodriguez from Clear Linux has written a very nice tutorial on how to use FMV.
