Hi all, while looking at the GHC 8 Trac page I encountered the page about the plans for the improved LLVM backend: https://ghc.haskell.org/trac/ghc/wiki/ImprovedLLVMBackend https://ghc.haskell.org/trac/ghc/wiki/ImprovedLLVMBackend I know nearly nothing about the internals of the GHC backend so I may be asking something trivial, but from reading that page I understand that GHC currently calls LLVM command line tools to optimize and compile the IR, is it right? LLVM is a C++ library, but it also exports a portable and stable C API which I think is already covered by the llvm-general package. So as someone who worked on LLVM in the past, and appreciated its library-based integration-friendly design I’m wondering why is GHC using the command line tools instead of linking to the library?
