-### LLVM variants

-In addition to the above, there are LLVM variants for the flavours `quick`,
-`prof`, `perf` and `bench`, available by appending a `-llvm` suffix (i.e.,
-`quick-llvm` for the LLVM variant of `quick`). These differ only in that there
-is an additional `-fllvm` flag in `hsDefault` when the stage0 compiler is GHC.
-See `src/Settings/Flavours/Llvm.hs` for details.
