Hi Martin, Having seen this before, I knew there had to be a compiler option for this... and checking the Debugging the Compiler section of the manual surfaces -dshow-passes, which should do exactly what you're asking for. I hope this helps! Richard

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.
