Some problems with LTO and why I don't normally develop with it enabled: - build time - code moves around all over the place so it is hard to compare size growth At least for my IDE flow, I use -L in most cases. Yes there are some boards which won't fit without LTO, but I don't see them much. So this is mostly a dev convenience / productivity tool. Regards, Simon
