我正在尝试在this code中重现Haskell编译 与该帖子中的内容相似:

ghc -fllvm quicksort.hs

这是quicksort.hs:

module Test where

quicksort [] = []
quicksort (p:xs) = (quicksort lesser) ++ [p] ++ (quicksort greater)
    where
        lesser = filter (< p) xs
        greater = filter (>= p) xs

但是我收到以下消息:llvm太新了:

[1 of 1] Compiling Test             ( quicksort.hs, quicksort.o )
You are using a new version of LLVM that hasn't been tested yet!
We will try though...
opt: /tmp/ghc6115_0/ghc6115_0.ll:12:6: error: unexpected type in metadata definition
!0 = metadata !{metadata !"top"}
     ^

现在这很奇怪,因为我正在使用llvm 3.8.0。这里发生了什么? 谢谢!
