#13535: vector test suite uses excessive memory on GHC 8.2 -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #10800 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): So it turns out that the failure of CSE isn't actually a regression. I can observe the same repeated bindings produced by 8.0.2. Regardless, I think the CSE failure should probably be considered a bug. Afterall, worker/wrapper originally applies this inline pragma to ensure that the wrapper doesn't inline before any possible specialisations have had a chance to do so. If we CSE'd in this case we aren't going to hide any specialisation opportunities as the bindings we are CSE'ing are all identical and should therefore have the same available specialisations. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13535#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
