Simon Peyton Jones pushed to branch wip/T23109 at Glasgow Haskell Compiler / GHC Commits: 35826d8b by Matthew Pickering at 2025-06-08T22:00:41+01:00 Hadrian: Add option to generate .hie files for stage1 libraries The +hie_files flavour transformer can be enabled to produce hie files for stage1 libraries. The hie files are produced in the "extra-compilation-artifacts" folder and copied into the resulting bindist. At the moment the hie files are not produced for the release flavour, they add about 170M to the final bindist. Towards #16901 - - - - - e2467dbd by Ryan Hendrickson at 2025-06-09T13:07:05-04:00 Fix various failures to -fprint-unicode-syntax - - - - - 43dd53c6 by Simon Peyton Jones at 2025-06-10T16:59:31+01:00 Make injecting implicit bindings into its own pass Previously we were injecting "impliicit bindings" (data constructor worker and wrappers etc) - both at the end of CoreTidy, - and at the start of CorePrep This is unpleasant and confusing. This patch puts it it its own pass, addImplicitBinds, which runs between the two. The function `GHC.CoreToStg.AddImplicitBinds.addImplicitBinds` now takes /all/ TyCons, not just the ones for algebraic data types. That change ripples through to - corePrepPgm - doCodeGen - byteCodeGen All take [TyCon] which includes all TyCons - - - - - c6a31618 by Simon Peyton Jones at 2025-06-10T16:59:31+01:00 Implement unary classes The big change is described exhaustively in Note [Unary class magic] in GHC.Core.TyCon Other changes * We never unbox class dictionaries in worker/wrapper. This has been true for some time now, but the logic is now centralised in functions in GHC.Core.Opt.WorkWrap.Utils, namely `canUnboxTyCon`, and `canUnboxArg` See Note [Do not unbox class dictionaries] in GHC.Core.Opt.WorkWrap.Utils. * Refactored the `notWorthFloating` logic in GHc.Core.Opt.SetLevels. I can't remember if I actually changed any behaviour here, but if so it's only in a corner cases. * Fixed a bug in `GHC.Core.TyCon.isEnumerationTyCon`, which was wrongly returning True for (##). * Remove redundant Role argument to `liftCoSubstWithEx`. It was always Representational. * I refactored evidence generation in the constraint solver: * Made GHC.Tc.Types.Evidence contain better abstactions for evidence generation. * I deleted the file `GHC.Tc.Types.EvTerm` and merged its (small) contents elsewhere. It wasn't paying its way. * Made evidence for implicit parameters go via a proper abstraction. Smaller things * Rename `isDataTyCon` to `isBoxedDataTyCon`. * GHC.Core.Corecion.liftCoSubstWithEx was only called with Representational role, so I baked that into the function and removed the argument. * Get rid of `GHC.Core.TyCon.tyConSingleAlgDataCon_maybe` in favour of calling `not isNewTyCon` at the call sites; more explicit. * Refatored `GHC.Core.TyCon.isInjectiveTyCon`; but I don't think I changed its behaviour * Moved `decomposeIPPred` to GHC.Core.Predicate - - - - - 164ac432 by Simon Peyton Jones at 2025-06-10T16:59:31+01:00 Accept GHCi debugger output change @alt-romes says this is fine - - - - - 5cd71bbc by Simon Peyton Jones at 2025-06-10T16:59:31+01:00 Renaming around predicate types .. we were (as it turned out) abstracting over type-class selectors in SPECIALISATION rules! Wibble isEqPred - - - - - 67591230 by Simon Peyton Jones at 2025-06-10T16:59:31+01:00 This increment adds tryTcS to support shortCutSolver * Make short-cut solver invoke the real solver, so that it works for type families. * Use the short-cut solver for quantified constraints too. * Use prepareSpecLHS for the old route too. Leave decomposeRuleLhs for RULES only. - - - - - 1a608495 by Simon Peyton Jones at 2025-06-10T16:59:31+01:00 Comments only - - - - - 125 changed files: - compiler/GHC/Builtin/Types.hs - compiler/GHC/ByteCode/InfoTable.hs -
