GHC always beta-reduces. It does not always inline. For that: -ddump-inlinings
Simon From: ghc-devs <ghc-devs-boun...@haskell.org> On Behalf Of David Feuer Sent: 26 March 2018 23:59 To: ghc-devs@haskell.org Subject: Missed beta reductions What's the best way to find spots where GHC saw a redex and choose not to beta reduce? Is there a flag for that? It could be useful when trying to figure out why rules aren't firing. David Feuer Well-Typed, LLP
