Pszemol,
If I were you, I would use some of the suggestions that have already been presented....
1. Try the --save-temps and/or -S option to gcc.
- No, this won't get you a whole lot further, but it will show you the details of assembly code for Nios II.
2. Try right-clicking on the project and scrolling to "Refresh" prior to "Building" your .s files.
- This refreshes your project's contents and, in theory, should make it "visible" to the build process.
3. Be aware that -O2 or -O3 optimized code does nearly as good a job of optimization as hand assembly, unless, of course, you're an assembly genious

I have used these sorts of methods to compile assembly using the IDE.
Cheers and Good luck!
