Concatenate it into an amalgamated unit at build time, then. This only adds a style requirement in that you can't use linking to enforce namespacing.

To expect the compiler to take advantage of that, you'd need to mark pretty much every function with static.

    GCC doesn't have a mature Z80 backend.

      I didn't mention GCC in that comment. The concept of default visibility is hardly GCC-specific. Also, it is not clear that the thread is still on the topic of z80 specifically or whole-project LTO generally. If you find yourself doing the latter outside of z80, you may find GCC useful. And hidden visibility is often useful a good default. If you want a z80-specific LTO option, sorry, I'm unfamiliar with any. That's a pretty niche ask.

I don't know of a mature Z80 compiler that supports LTO. The thread at this point is on the topic of "so your compiler doesn't support LTO, how can we 80/20 our way to the same semantics"

  I believe the LTO implementations of modern compilers handle this for you? (https://clang.llvm.org/docs/LTOVisibility.html https://clang.llvm.org/docs/LTOVisibility.html) Edit: Wow, as a result of your other comment about GCC I was surprised to learn that none of the Z80 compilers I could find appear to support this sort of thing. It looks like there was (previously?) an effort to put together a Z80 backend for LLVM, but my search results didn't look promising.

    Yeah, it's a newer concept for the compiler space (it relies on having a lot of compiler host memory, more than you might think), and I'm not sure that the more niche compilers have had time to get this feature yet.
