#11437: Don't put static (version-based) feature gates in compilerInfo -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.11 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 ezyang): The feature gates which I want to remove are `Support parallel --make`, `Support reexported-modules`, `Support thinning and renaming package flags`, `Requires unified installed package IDs` and `Uses package keys`. I want to remove these because, if this is followed to its logical extreme, you'll end up putting lots of feature gates in `compilerInfo`, ballooning its size, slowing down Cabal (since it always has to parse this structure when it is configuring). What should you put in this structure? If we want to continue feature-testing, we should do it another way, like giving a list of supported flags, etc. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11437#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
