Bodigrim pushed to branch wip/warning-for-last-and-init at Glasgow Haskell Compiler / GHC Commits: 94b62aa7 by Simon Peyton Jones at 2025-09-08T03:37:14-04:00 Refactor ForAllCo This is a pure refactor, addressing #26389. It arranges that the kind coercion in a ForAllCo is a MCoercion, rather than a plain Coercion, thus removing redundancy in the common case. See (FC8) in Note [ForAllCo] It's a nice cleanup. - - - - - 624afa4a by sheaf at 2025-09-08T03:38:05-04:00 Use tcMkScaledFunTys in matchExpectedFunTys We should use tcMkScaledFunTys rather than mkScaledFunTys in GHC.Tc.Utils.Unify.matchExpectedFunTys, as the latter crashes when the kind of the result type is a bare metavariable. We know the result is always Type-like, so we don't need scaledFunTys to try to rediscover that from the kind.

This test case was extracted from Agda.

In module `Settings.Warnings`, applies `-Wno-x-partial` to the `filepath`, and `parsec` packages (outside GHC's repository). Also bumps submodules. - - - - - 60 changed files: - compiler/GHC/Core/Coercion.hs - compiler/GHC/Core/Coercion.hs-boot - compiler/GHC/Core/Coercion/Opt.hs - compiler/GHC/Core/Lint.hs - compiler/GHC/Core/Opt/Arity.hs - compiler/GHC/Core/Reduction.hs - compiler/GHC/Core/TyCo/FVs.hs - compiler/GHC/Core/TyCo/Rep.hs - compiler/GHC/Core/TyCo/Subst.hs - compiler/GHC/Core/TyCo/Tidy.hs - compiler/GHC/Core/Type.hs - compiler/GHC/Core/Unify.hs - compiler/GHC/Core/Utils.hs - compiler/GHC/CoreToIface.hs - compiler/GHC/Driver/Env.hs - compiler/GHC/Driver/Session/Units.hs - compiler/GHC/Iface/Rename.hs - compiler/GHC/Iface/Syntax.hs - compiler/GHC/Iface/Type.hs - compiler/GHC/IfaceToCore.hs - compiler/GHC/Prelude/Basic.hs - compiler/GHC/Tc/Instance/Family.hs - compiler/GHC/Tc/Module.hs - compiler/GHC/Tc/TyCl/Utils.hs - compiler/GHC/Tc/Utils/TcMType.hs - compiler/GHC/Tc/Utils/TcType.hs - compiler/GHC/Tc/Utils/Unify.hs - compiler/GHC/Types/Id/Make.hs - compiler/GHC/Unit/Home/Graph.hs - compiler/GHC/Unit/Home/PackageTable.hs - ghc/GHCi/UI.hs - ghc/Main.hs - hadrian/src/Settings/Warnings.hs - libraries/base/changelog.md - libraries/ghc-boot-th/GHC/Boot/TH/Ppr.hs - libraries/ghc-internal/src/GHC/Internal/Float.hs - libraries/ghc-internal/src/GHC/Internal/List.hs - libraries/ghc-internal/src/GHC/Internal/System/IO.hs - libraries/ghc-internal/src/GHC/Internal/TH/Syntax.hs - libraries/template-haskell/vendored-filepath/System/FilePath/Posix.hs - libraries/template-haskell/vendored-filepath/System/FilePath/Windows.hs - testsuite/tests/driver/j-space/jspace.hs - testsuite/tests/rts/KeepCafsBase.hs - testsuite/tests/simplCore/should_compile/OpaqueNoCastWW.stderr - + testsuite/tests/typecheck/should_compile/T26154.hs - + testsuite/tests/typecheck/should_compile/T26154_A.hs - + testsuite/tests/typecheck/should_compile/T26154_B.hs - + testsuite/tests/typecheck/should_compile/T26154_B.hs-boot - + testsuite/tests/typecheck/should_compile/T26154_Other.hs - + testsuite/tests/typecheck/should_compile/T26277.hs - testsuite/tests/typecheck/should_compile/all.T - utils/check-exact/Main.hs - utils/check-exact/Transform.hs - utils/check-exact/Utils.hs - utils/ghc-pkg/Main.hs - utils/ghc-toolchain/src/GHC/Toolchain/CheckArm.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml.hs - utils/haddock/haddock-library/src/Documentation/Haddock/Parser.hs - utils/hpc - utils/hsc2hs The diff was not included because it is too large.
