The same arguments as for free variables apply, though: It's occurrence information which is probably fragile enough to just be generated on demand.
I think so too. That is, let's not generate it at the beginning. If LLF wants it, it's probably best just to calculate it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15770#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
