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

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 So far I've found little bits in the GHC manual, like: 4.16.3. How to read Core syntax http://www.haskell.org/ghc/docs/latest/html/users_guide/options-debugging.ht... (and the Encoding module has the actual rules for the Unique names) http://darcs.haskell.org/ghc/compiler/utils/Encoding.hs 6.2. Faster: producing a program that runs quicker http://www.haskell.org/ghc/docs/latest/html/users_guide/faster.html (see "How do I find out a function's strictness?") Any other hints? Alistair
