What LLVM versions are supported by the codegen?

[jonathan-il]

On the documentation, LLVM 7 is used. I am just curious if any version of LLVM can be used or if v7 is a hard requirement. If it is a hard requirement, do you have any estimate of the work that would be involved in bringing it up to say the 12.x version?

The LLVM version is tied to llvm-hs. So currently it will work only with LLVM 7.
