Synopsis:      FFI bindings to the LLVM compiler toolkit.
Description:
  FFI bindings to the LLVM compiler toolkit.
  .
  Installation cannot be done fully automatically.
  It would require Cabal code that is bound to certain Cabal versions
  and is prone to fail.
  We give several non-automatic ways
  that also allow you to choose a particular LLVM version.
  .
  First possibility is to point Cabal
  to the LLVM installation directories manually.
  It is recommended to add options to your global @.cabal/config@:
  .
  > extra-include-dirs: /usr/lib/llvm-16/include
  > extra-lib-dirs: /usr/lib/llvm-16/lib
  .
  This works for both @v1-build@ and @v2-build@.
  The shown paths work for Debian and Ubuntu
  using the LLVM repositories at <https://apt.llvm.org/>.
  You can obtain them with
  .
  > llvm-config-16 --includedir --libdir
  .
  You can choose specific LLVM versions per project.
  For @v1-builds@ it works like so:
  .
  > cabal install -fllvm900 --extra-include-dirs=$(llvm-config-9 --includedir) --extra-lib-dirs=$(llvm-config-9 --libdir) yourpackage
  .
  For Nix-style build you must add some options
  to the @cabal.project.local@ file of your LLVM-related project:
  .
  > package llvm-ffi
  >   flags: +llvm900
  >   extra-include-dirs: /usr/lib/llvm-9/include
  >   extra-lib-dirs: /usr/lib/llvm-9/lib
  .
  The second way uses @pkg-config@.
  You can store above paths permanently in a @pkg-config@ file like @llvm.pc@.
  The optimal way would be if LLVM installations or GNU/Linux distributions
  would contain such a file, but they don't.
  Instead, you may generate it using the @llvm-pkg-config@ package
  or write one manually.
  Then you run
  .
  > cabal install -fpkgConfig
  .
  We try to stay up to date with LLVM releases.
  The current version of this package is compatible with LLVM 8-16.
  Please understand that the package may or may not work
  against older LLVM releases.
  .
  Warning for inplace builds:
  Re-configuring the package using, say @-fllvm1100@,
  and re-buildung it might result in corrupt code.
  You must make sure that the stuff in @cbits@ is re-compiled.
  Cabal or GHC may forget about that.
  You are safe if you run @cabal clean@.
  .
  Caution: Ugly crashes can occur
  if you have configured paths for LLVM version X in @.cabal/config@
  and try to build @llvm-ffi@ for a different LLVM version Y.
  Counterintuitively, global search paths have higher precedence
  than local ones: <https://github.com/haskell/cabal/issues/7782>.
  But that does not simply mean
  that the local configuration is ignored completely.
  Instead the local library file is found,
  because its name libLLVM-Y.so is unique,
  whereas the include file names clash,
  thus the ones from the global include directory are used.
