- Subject: Optimization across translation units
Hi everyone.
For manageability, I have broken up one source file that was 1500 lines long into several that are each a couple of hundred lines long. Now my executable is bigger. In order to make it work I had to take some functions that were static and make them non-static (and extern them in a .h file). It is obvious that the compiler is no longer able to optimize as much.
Does anyone have any ideas on how to get decent optimization where a function is calling a function in a different translation unit?
