Eg (A) let d = $dfblah d1 in ....(f d).... (B) \d. ....(f d).... In (A) it's probably worth specialising f; in (B) it isn't. Previously we were relying on d's unfolding, but the specialiser does cloning as it goes, which discards the unfolding. So we were simply discarding all specialisations for functions with local dictionary bindings! This bug seems to have been there for a long time. This is what originally caused Trac #5113. Then we went through a phase where local bindings were not generalised, and that meant there was no locally overloaded f to specialise; so the performance problem appeared to be fixed. But now we are generalising local bindings again, so it re-appeared. This patch fixes the original problem. compiler/specialise/Specialise.lhs | 390 ++++++++++++++++++++---------------- 1 files changed, 214 insertions(+), 176 deletions(-) }}} -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5113#comment:6> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
