But even before this you had store to load forwarding on x86. I'm not saying you have, but before inventing a performance problem it is worth spending time trying to diagnose it with thorough profiling (e.g. [1]). The Fedora frame pointer patch did a thorough performance analysis and performance will be revisited again. Unfortunately there are a lot of arm chair performance experts who haven't spent time looking into the details.
