We just need to track which join points are still currently valid.
Yes, and that would not be hard. Just keep a join-point reverse map in the CSEnv, alongside the existing `cs_map`; and discard it when going into non-tail positions. A relatively easy win, but as you say a modest one. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13219#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
