I think LIKELY/UNLIKELY is not helpful if you compile with LTO/PGO enabled. So, I would try that first. Also, if you use relatively small static functions that are defined before use (no forward declarations), I have found that GCC is usually smart about inlining them. So, I don't think you should have to use "static inline" rather than just "static". Good work looking into this. Should be some relatively easy performance win.
