[Haskell-cafe] Re: How to read -ddump-hi output (and other phases) from GHC

Alistair Bayley skrev:

I'm collecting links to documents describing some of GHC's optimisation output flags, like -ddump-hi and -ddump-simpl. I'll add stuff to this wiki page: http://www.haskell.org/haskellwiki/Performance/GHC Any other hints?

Thanks. I will definitely use such a guide. I only tried reading core once, but I used the --dump-X options together with compilation for profiling. Inserting my own cost-centres then gave me very clear labels in the code at the places I wanted them. I felt this made it easier for me to identify the different functions and other parts of the code within the core file. Johan
