From f63bc730c7ea42ca6882f8078eb86be8bf1cc6ad Mon Sep 17 00:00:00 2001 From: Herbert Valerio Riedel Date: Tue, 19 Sep 2017 14:35:36 -0400 Subject: compiler: introduce custom "GhcPrelude" Prelude This switches the compiler/ component to get compiled with -XNoImplicitPrelude and a `import GhcPrelude` is inserted in all modules. This is motivated by the upcoming "Prelude" re-export of `Semigroup((<>))` which would cause lots of name clashes in every modulewhich imports also `Outputable` Reviewers: austin, goldfire, bgamari, alanz, simonmar Reviewed By: bgamari Subscribers: goldfire, rwbarton, thomie, mpickering, bgamari Differential Revision: https://phabricator.haskell.org/D3989 --- compiler/utils/Outputable.hs-boot | 2 ++ 1 file changed, 2 insertions(+) (limited to 'compiler/utils/Outputable.hs-boot') diff --git a/compiler/utils/Outputable.hs-boot b/compiler/utils/Outputable.hs-boot index 980c186889..ad7d091833 100644 --- a/compiler/utils/Outputable.hs-boot +++ b/compiler/utils/Outputable.hs-boot @@ -1,5 +1,7 @@ module Outputable where +import GhcPrelude + data SDoc showSDocUnsafe :: SDoc -> String -- cgit v1.2.1
