The optimization is eating your box alive, the rest is peanuts compared to that. At least in the old times, the optimizer would only operate locally in each compilation unit. If you split it into many compilation units then there are less optimizations possible. For example you can't inline a function that is defined in another compilation unit, because you don't know the function body. Of course things are more difficult nowadays since compilers want to overcome this limitation. GCC can now do optimizations across compilation units. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
