#11770: Demand analysis: Wrong one-shot annotation due to fixed-point iteration -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Replying to [comment:3 nomeata]: the demand analyzer will not be reflected here, and hence not used in later passes, e.g. by the simplifier when trying to to floating a let into a lambda? No, that'll be fine: the occurrence analyser runs before each pass of the simplifier.
Note that due to the magic `oneShot` function, there might be one-shot info worth preserving.
Good point! Please comment this prominently with `updOneShotInfo`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11770#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
