First off, the size increase only matters if it actually increases the cache footprint. And it may, but.. Secondly, my whole point here has been that we should not rely on gcc doing things behind our back, because gcc will generally do the wrong thing. If we decided to be more active about this, we could just choose to find the places that matter (in hot code) and fix _those_. Thirdly, you're just replacing _one_ random gcc choice with _another_ random one. What happens when you say -fno-inline-functions-called-once? Does it disable inlining for those functions IN GENERAL, or just for the LARGE ones? See?
