should the Makefile support compiling to shared lib?

The libsysy.so could be used in koopa's interpreter. It's very useful for debugging IR passes since it's decoupled with the backend.

So I wonder if compiling the runtime lib into libsysy.so is needed.

Once it's done, this repo's link could be added to interpreter's doc for clearer usage.

That's okay. If the only change is adding a compilation command to the Makefile, why not? 😂

Although the standard way (mentioned in the online doc) to debug Koopa IR is to convert it to LLVM IR and compile & link with libsysy.a. Besides, using this interpreter to debug IR is not reliable as the interpreter may also contains bugs.

If it's necessary to use the interpreter to do something, we can move it to a separate repo.
