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 | 2 ++ 1 file changed, 2 insertions(+) (limited to 'compiler/utils/Outputable.hs') diff --git a/compiler/utils/Outputable.hs b/compiler/utils/Outputable.hs index 5cd7656b4f..d257e3ec9f 100644 --- a/compiler/utils/Outputable.hs +++ b/compiler/utils/Outputable.hs @@ -85,6 +85,8 @@ module Outputable ( pprDebugAndThen, callStackDoc ) where +import GhcPrelude + import {-# SOURCE #-} DynFlags( DynFlags, hasPprDebug, hasNoDebugOutput, targetPlatform, pprUserLength, pprCols, useUnicode, useUnicodeSyntax, -- cgit v1.2.1
