That's a good solution. It should also cut the compilation time that is ATM mostly startup time. OTOH I realized the reason of the 45K, trampolines are not optimized ATM so GCC does not prune unused functions. I'll modify to have them compiled at least at O1 and follow-up on the corresponding footprint. Andrea
