This is a follow-up to #39129. The current state of the PR is that by default, e…verything works as normal, except during the build we generate both libjulia-internal (which does not link against LLVM) and libjulia-codegen (which does). The loader attempts to load libjulia-codegen after libjulia-internal. If that fails, it populates the codegen entry points with fallbacks in libjulia-internal that do nothing. That means you can simply delete libjulia-codegen, start with --compile=no, and enjoy a compiler-free julia runtime (assuming you don't actually need the compiler of course :smile: ). This probably still needs a bunch of cleanup, and it also tends to segfault with --compile=no, which I assume can be fixed. All in all, the loader framework we have is quite a nice way to separate the system into multiple optional components, and I foresee doing more of that. The parser and front-end would be another logical component to separate (and then ultimately replace with a new implementation written in julia and separately compiled!). It would be nice if we could streamline adding plugins a bit --- naturally, we thought the loader would only ever load one thing, so a few too many places need to be modified to add another.
