Apoorv Ingle pushed to branch wip/spj-apporv-Oct24 at Glasgow Haskell Compiler / GHC Commits: 5b5d9d47 by Ben Gamari at 2025-08-25T14:29:35-04:00 Revert "STM: don't create a transaction in the rhs of catchRetry# (#26028)" This reverts commit 0a5836891ca29836a24c306d2a364c2e4b5377fd - - - - - 10f06163 by Cheng Shao at 2025-08-25T14:30:16-04:00 wasm: ensure setKeepCAFs() is called in ghci This patch is a critical bugfix for #26106, see comment and linked issue for details. - - - - - bedc1004 by Cheng Shao at 2025-08-26T09:31:18-04:00 compiler: use zero cost coerce in hoopl setElems/mapToList This patch is a follow-up of !14680 and changes setElems/mapToList in GHC/Cmm/Dataflow/Label to use coerce instead of mapping mkHooplLabel over the keys. - - - - - 13250d97 by Ryan Scott at 2025-08-26T09:31:59-04:00 Reject infix promoted data constructors without DataKinds In the rename, make sure to apply the same `DataKinds` checks for both `HsTyVar` (for prefix promoted data constructors) and `HsOpTy` (for infix promoted data constructors) alike. Fixes #26318. - - - - - 34f4884d by Apoorv Ingle at 2025-08-26T11:24:19-05:00 This commit: - Streamlines implementations of `tcExpr` and `tcXExpr` to work on `XExpr` Calls `setInGeneratedCode` everytime the typechecker goes over an `XExpr` - Kills `VACtxt` (and its associated VAExpansion and VACall) datatype, it is subsumed by simply a SrcSpan. - Kills the function `addHeadCtxt` as it is now mearly setting a location - The function `tcValArgs` does its own argument number management - Makes `splitHsApps` not look through `XExpr` - `tcExprSigma` is called if the head of the expression after calling `splitHsApps` turns out to be an `XExpr` - Removes location information from `OrigPat` payload - Removes special case of tcBody from `tcLambdaMatches` - Removes special case of `dsExpr` for `ExpandedThingTc` - Moves `setQLInstLevel` inside `tcInstFun` - Rename `HsThingRn` to `SrcCodeCtxt` - Kills `tcl_in_gen_code` and `tcl_err_ctxt`. It is subsumed by `ErrCtxtStack` - Kills `ExpectedFunTyOrig`. It is subsumed by `CtOrigin` - Fixes `CtOrigin` for `HsProjection` case in `exprCtOrigin`. It was previously assigned to be `SectionOrigin`. It is now just the expression - Adds a new `CtOrigin.ExpansionOrigin` for storing the original syntax - Adds a new `CtOrigin.ExpectedTySyntax` as a replacement for `ExpectedTySyntaxOp`. Cannot kill the former yet because of `ApplicativeDo` - Renames `tcMonoExpr` -> `tcMonoLExpr`, `tcMonoExprNC` -> `tcMonoLExpr` - Renames `EValArg`, `EValArgQL` fields: `ea_ctxt` -> `ea_loc_span` and `eaql_ctx` -> `eaql_loc_span` Notes added [Error Context Stack] Notes updated Note [Expanding HsDo with XXExprGhcRn] ------------------------- Metric Decrease: T9020 ------------------------- - - - - - 66 changed files: - compiler/GHC/Cmm/Dataflow/Label.hs - compiler/GHC/Hs.hs - compiler/GHC/Hs/Expr.hs - compiler/GHC/Hs/Instances.hs - compiler/GHC/HsToCore/Expr.hs - compiler/GHC/HsToCore/Match.hs - compiler/GHC/HsToCore/Pmc.hs - compiler/GHC/HsToCore/Quote.hs - compiler/GHC/HsToCore/Ticks.hs - compiler/GHC/Rename/Expr.hs - compiler/GHC/Rename/HsType.hs - compiler/GHC/Tc/Errors.hs - compiler/GHC/Tc/Errors/Ppr.hs - compiler/GHC/Tc/Gen/App.hs - + compiler/GHC/Tc/Gen/App.hs-boot - compiler/GHC/Tc/Gen/Do.hs - compiler/GHC/Tc/Gen/Expr.hs - compiler/GHC/Tc/Gen/Expr.hs-boot - compiler/GHC/Tc/Gen/Head.hs - compiler/GHC/Tc/Gen/Match.hs - compiler/GHC/Tc/Gen/Pat.hs - compiler/GHC/Tc/Instance/Class.hs - compiler/GHC/Tc/Types/ErrCtxt.hs - compiler/GHC/Tc/Types/LclEnv.hs - compiler/GHC/Tc/Types/Origin.hs - compiler/GHC/Tc/Utils/Monad.hs - compiler/GHC/Tc/Utils/Unify.hs - docs/users_guide/9.16.1-notes.rst - rts/PrimOps.cmm - rts/RaiseAsync.c - rts/STM.c - testsuite/tests/default/default-fail05.stderr - testsuite/tests/indexed-types/should_fail/T2693.stderr - testsuite/tests/indexed-types/should_fail/T5439.stderr - − testsuite/tests/lib/stm/T26028.hs - − testsuite/tests/lib/stm/T26028.stdout - − testsuite/tests/lib/stm/all.T - testsuite/tests/parser/should_fail/RecordDotSyntaxFail10.stderr - testsuite/tests/parser/should_fail/RecordDotSyntaxFail11.stderr - testsuite/tests/plugins/test-defaulting-plugin.stderr - testsuite/tests/polykinds/T13393.stderr - testsuite/tests/printer/T17697.stderr - testsuite/tests/rep-poly/RepPolyDoBind.stderr - testsuite/tests/rep-poly/RepPolyDoBody1.stderr - testsuite/tests/rep-poly/RepPolyDoBody2.stderr - testsuite/tests/rep-poly/RepPolyRecordUpdate.stderr - testsuite/tests/typecheck/should_compile/T14590.stderr - testsuite/tests/typecheck/should_compile/valid_hole_fits.stderr - testsuite/tests/typecheck/should_fail/DoExpansion1.stderr - testsuite/tests/typecheck/should_fail/DoExpansion2.stderr - testsuite/tests/typecheck/should_fail/T10971d.stderr - testsuite/tests/typecheck/should_fail/T13311.stderr - testsuite/tests/typecheck/should_fail/T24064.stderr - + testsuite/tests/typecheck/should_fail/T26318.hs - + testsuite/tests/typecheck/should_fail/T26318.stderr - testsuite/tests/typecheck/should_fail/T3323.stderr - testsuite/tests/typecheck/should_fail/T3613.stderr - testsuite/tests/typecheck/should_fail/T7851.stderr - testsuite/tests/typecheck/should_fail/T8603.stderr - testsuite/tests/typecheck/should_fail/T9612.stderr - testsuite/tests/typecheck/should_fail/all.T - testsuite/tests/typecheck/should_fail/tcfail102.stderr - testsuite/tests/typecheck/should_fail/tcfail128.stderr - testsuite/tests/typecheck/should_fail/tcfail168.stderr - testsuite/tests/warnings/should_fail/CaretDiagnostics1.stderr - utils/jsffi/dyld.mjs The diff was not included because it is too large.
