For the code generation and compilation (LLVM related crates), in the Zom compiler. We could replace it with the C++ library, because it's the official way to use LLVM, there is some issues in this project that is related to LLVM not working : #24, #20, #23, #21. If we replace it with an a C++ package, we could just follow the doc and not wasting its time to found the function in Inkwell, etc ..
Pros
We can follow the LLVM docs without any trouble to find the corresponding function in Inkwell
Some issues (#24, #20, #23, #21) could be solved.
Cons
Safety, C++ is safer than C but C++ is not safe as Rust is.
Some layer between Rust and C++ is needed, you can find some solution below,
Solution N°1
Write a serializer that serialize the result of the type checking (or the end of the compilation pipeline that doesn't need LLVM). And the C++ program will be executed in a child process, with the serialized input, and we deserialize and return the output desired by the compiler.
Solution N°2
Write a C++ lib that uses LLVM and emit the desired output by the compiler, and his functions is called by the the Zom compiler with the Rust FFI to C++.
