Compiling with "-nodefaultlibs" should do the trick to remove the interrupt code generation, that's the easy part. What i want is to manually build the interrupt vector and implement the ISRs (complete with context saving and context restoring operations). It's kind of a challenge, where the compiler is supposedly more primitive and doesn't know what it is an interruption.
i guess i didn't make my self clear, sorry.
Creating a naked function is not quite there yet, but thank you!
i'm going to start by looking at the .S assembly, but that's not always the best way to understand what's going on. That's why i'm looking for a more explanatory document.
