AFAIK there's existing microarchitectural optimizations in gcc and clang already, so it's reasonable to assume that AMD would add just such a feature.
But most people don't enable these features when building because they often make the resulting executable/library unusable on general CPUs. However, businesses/individuals with more specialized needs and better control over their targets often do capitalize on these.
