#11731: Simplifier: Inlining trivial let can lose sharing -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: bug | Status: patch 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): Phab:D2064 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): Sounds like a plan. I am currently checking the effect of a very late, non-ww, demand analyzer. Are you sure that that is the most convenient place? * It would no longer get erased with `-fstrictness -fno-worker-wrapper`. Although we might argue that this is not a supported configuration. * Since the worker-wrapper pass happens before the next occurrence analyzer (does it?), the occurrence analyzer no longer sees the `1*` `demandInfo` and thus cannot set the `oneShotInfo`. Why not do it in the occurrence analyser? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11731#comment:27 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
