From 17fcce4ca5bf1418d8f335e869d328e1913d3f95 Mon Sep 17 00:00:00 2001 From: Zubin Duggal Date: Tue, 16 May 2023 14:34:19 +0530 Subject: compiler: Remove instance Binary Char It is generally not a good idea to serialise strings as [Char] into interface files, as upon deserialisation each of these would be turned into a highly memory inefficient structure mostly composed of cons cells and pointers. If you really want to serialise a Char, use the SerialisableChar newtype. --- compiler/GHC/CoreToIface.hs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'compiler/GHC/CoreToIface.hs') diff --git a/compiler/GHC/CoreToIface.hs b/compiler/GHC/CoreToIface.hs index 566900cdb4..81f4a17823 100644 --- a/compiler/GHC/CoreToIface.hs +++ b/compiler/GHC/CoreToIface.hs @@ -320,7 +320,7 @@ toIfaceCoercionX fr co go_prov :: UnivCoProvenance -> IfaceUnivCoProv go_prov (PhantomProv co) = IfacePhantomProv (go co) go_prov (ProofIrrelProv co) = IfaceProofIrrelProv (go co) - go_prov (PluginProv str) = IfacePluginProv str + go_prov (PluginProv str) = IfacePluginProv (mkFastString str) go_prov (CorePrepProv b) = IfaceCorePrepProv b toIfaceTcArgs :: TyCon -> [Type] -> IfaceAppArgs -- cgit v1.2.1
