#13426: compile-time memory-usage regression for DynFlags between GHC 8.0 and GHC 8.2 -------------------------------------+------------------------------------- Reporter: hvr | Owner: (none) Type: bug | Status: new Priority: high | 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: | Differential Rev(s): Phab:D3399, Wiki Page: | Phab:D3400, Phab:D3421 -------------------------------------+------------------------------------- Comment (by simonpj):
would be better to force the types when we take them out of the SimplCont and put them into the actual program?
Yes for the type in the `Stop` continuation; but I think no for the types in `ApplyToTy` continuation, which will certainly be used. I'd force the latter on the way in; but the former only on the way out in `contResultType`. Does that make sense? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13426#comment:29 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
