You can disable this by turning off the `llvm` package flag. Using a [`cabal.project` file](https://cabal.readthedocs.io/en/latest/cabal-project.html#cfg-field-constraints), this is most conveniently done by adding the following:--    constraints: flatparse -llvm--[Using `stack.yaml`](https://docs.haskellstack.org/en/stable/yaml_configuration/#flags), you can add the following:+### LLVM -    flags:-      flatparse:-        llvm: false+It is advised to build with [`-fllvm`+option](https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/codegens.html#llvm-code-generator-fllvm)+when using this package, since that can result in significant speedups (20-40%+from what I've seen). Additionally, you can enable `-fllvm` for `flatparse`+specifically by enabling the `llvm` package flag. However, this has minor+impact, since almost all parser code will be typically inlined into modules+outside `flatparse`, and compiled there.  ## Features and non-features
