I continue to maintain the other LLVM wrapper, based on the original llvm 
package by O'Sullivan and Augustsson:
    https://hackage.haskell.org/package/llvm-tf
    https://hackage.haskell.org/package/llvm-ffi

However, I also support only up to LLVM-9 for now. Updating the Haskell 
bindings is tedious because LLVM changes details often and the changes are 
hardly documented.

On the other hand, I have long-standing problems with LLVM. E.g. when I 
start optimizing via LLVM's C interface the result is much worse than the 
one produced by the opt command-line utility. I would like to know, 
whether llvm-hs has this problem, too. However, I miss a simple example 
for demonstration.
