Flag llvm
  Description:  Compile via LLVM. This produces much better object code,
                but you need to have the LLVM compiler installed.
  -- If you enable this and get errors like "Error: can't resolve `.rodata' {.rodata section}"
  -- then GHC doesn't like your version of LLVM!
  Default:      False

Flag opt
  Description: Turn on library optimizations
  Default:     True

  -- Due to #12152, the file containing the definition of `Zq::q` must be linked first,
  -- otherwise dynamic linking (`cabal repl` or `stack ghci`) results in the error:
  -- "Loading temp shared object failed: /tmp/ghc54651_0/libghc_1.so: undefined symbol _ZN2Zq1qE"
  -- For `cabal repl`, we can simply reorder the list so that the file that should be linked
  -- first comes first in the list. However `stack ghci` always links alphabetically,
  -- so we really just have to define `Zq::q` in the first file alphabetically.
