[Haskell-cafe] Profiling analyzing ghc compilation

Hi, Is there a way to profile (time/space) GHC compilation itself, I'd be interested in what compilation steps in compiling my project take long and how much RAM it uses/why it uses so much RAM, so I can identify what to rewrite, remove, and split to get a leaner build. Thanks, Martin PS.: I hope this is the right place to ask this.
