Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: f34c79ee by Alan Zimmerman at 2026-10-15T04:54:47-04:00 EPA: Start using vocurly as basis for AnnListLayout For the existing cases that populate AnnList. This uses AnnListBraces when braces are explicitly supplied, and AnnListLayout when vocurly is used The change also shows up AnnList usages that can never capture layout, these are cleared up later. - - - - - 2 changed files: - compiler/GHC/Parser.y - testsuite/tests/parser/should_compile/DumpSemis.stderr Changes: ===================================== compiler/GHC/Parser.y ===================================== @@ -1797,10 +1797,10 @@ cvars1 :: { [RecordPatSynField GhcPs] } where_decls :: { LocatedA (OrdList (LHsDecl GhcPs), EpToken "where", AnnList) } : 'where' '{' decls '}' {% amsA' (sLL $1 $> (thdOf3 $ unLoc $3, epTok $1, - AnnList (AnnListLayout (fstOf3 $ unLoc $3)) (ListBraces (epTok $2) (epTok $4)) (sndOf3 $ unLoc $3))) } + AnnList AnnListBraces (ListBraces (epTok $2) (epTok $4)) (sndOf3 $ unLoc $3))) } | 'where' vocurly decls close {% amsA' (sLL $1 $3 (thdOf3 $ unLoc $3, epTok $1, - AnnList (AnnListLayout (fstOf3 $ unLoc $3)) ListNone (sndOf3 $ unLoc $3))) } + AnnList (AnnListLayout (glR $3)) ListNone (sndOf3 $ unLoc $3))) } pattern_synonym_sig :: { LSig GhcPs } : 'pattern' con_list '::' sigtype @@ -1936,7 +1936,7 @@ decls :: { Located (EpaLocation, [EpToken ";"], OrdList (LHsDecl GhcPs)) } | {- empty -} { noLoc (noAnn, [],nilOL) } decllist :: { Located (AnnList,Located (OrdList (LHsDecl GhcPs))) } - : '{' decls '}' { sLL $1 $> (AnnList (AnnListLayout (fstOf3 $ unLoc $2)) (ListBraces (epTok $1) (epTok $3)) (sndOf3 $ unLoc $2) + : '{' decls '}' { sLL $1 $> (AnnList AnnListBraces (ListBraces (epTok $1) (epTok $3)) (sndOf3 $ unLoc $2) ,sL1 $2 $ thdOf3 $ unLoc $2) } | vocurly decls close { sL1 $2 (AnnList (AnnListLayout (fstOf3 $ unLoc $2)) ListNone (sndOf3 $ unLoc $2) ,sL1 $2 $ thdOf3 $ unLoc $2) } @@ -1952,7 +1952,7 @@ binds :: { Located (HsLocalBinds GhcPs) } ; return (sL1 $1 $ HsValBinds (EpAnn (glR $1) (AnnList la p s) cs, noEpTok) val_binds)} } | '{' dbinds '}' {% acs (comb3 $1 $2 $3) (\loc cs -> (L loc - $ HsIPBinds (EpAnn (spanAsAnchor (comb3 $1 $2 $3)) (AnnList (AnnListLayout$ glR $2) (ListBraces (epTok $1) (epTok $3)) []) cs, noEpTok) (IPBinds noExtField (reverse $ unLoc $2)))) } + $ HsIPBinds (EpAnn (spanAsAnchor (comb3 $1 $2 $3)) (AnnList AnnListBraces (ListBraces (epTok $1) (epTok $3)) []) cs, noEpTok) (IPBinds noExtField (reverse $ unLoc $2)))) } | vocurly dbinds close {% acs (gl $2) (\loc cs -> (L loc $ HsIPBinds (EpAnn (glR $1) (AnnList (AnnListLayout $ glR $2) ListNone []) cs, noEpTok) (IPBinds noExtField (reverse $ unLoc $2)))) } @@ -3543,12 +3543,12 @@ guardquals1 :: { Located [LStmt GhcPs (LHsExpr GhcPs)] } altslist(PATS) :: { forall b.
