Apoorv Ingle pushed to branch wip/ani/kill-popErrCtxt at Glasgow Haskell Compiler / GHC Commits: 6b2c022b by Apoorv Ingle at 2025-09-11T14:58:03-05:00 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 ------------------------- - - - - - e95889e1 by Apoorv Ingle at 2025-09-14T22:26:20-05:00 some initial experiment to make ErrCtxt more expressive - - - - - 4eaece2c by Apoorv Ingle at 2025-09-18T17:28:18-05:00 bring back tcl_in_gen_code - - - - - 60 changed files: - 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/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 - + testsuite/tests/deSugar/should_compile/T10662 - testsuite/tests/default/default-fail05.stderr - + testsuite/tests/ghci.debugger/Do - + testsuite/tests/ghci.debugger/Do.hs - + testsuite/tests/ghci.debugger/T25996.hs - testsuite/tests/indexed-types/should_fail/T2693.stderr - testsuite/tests/indexed-types/should_fail/T5439.stderr - 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/T25996.hs - 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/T25970.hs - + testsuite/tests/typecheck/should_fail/T25996.hs - 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/tcfail102.stderr - testsuite/tests/typecheck/should_fail/tcfail128.stderr - testsuite/tests/typecheck/should_fail/tcfail168.stderr - testsuite/tests/warnings/should_fail/CaretDiagnostics1.stderr The diff was not included because it is too large.
