Apoorv Ingle pushed to branch wip/spj-apporv-Oct24 at Glasgow Haskell Compiler / GHC Commits: 03555ed8 by Sylvain Henry at 2025-08-10T22:20:57-04:00 Handle non-fractional CmmFloats in Cmm's CBE (#26229) Since f8d9d016305be355f518c141f6c6d4826f2de9a2, toRational for Float and Double converts float's infinity and NaN into Rational's infinity and NaN (respectively 1%0 and 0%0). Cmm CommonBlockEliminator hashing function needs to take these values into account as they can appear as literals now. See added testcase. - - - - - 6c956af3 by J. Ryan Stinnett at 2025-08-10T22:21:42-04:00 Fix extensions list in `DoAndIfThenElse` docs - - - - - 6dc420b1 by J. Ryan Stinnett at 2025-08-10T22:21:42-04:00 Document status of `RelaxedPolyRec` extension This adds a brief extension page explaining the status of the `RelaxedPolyRec` extension. The behaviour of this mode is already explained elsewhere, so this page is mainly for completeness so that various lists of extensions have somewhere to point to for this flag.

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 ------------------------- - - - - - 69 changed files: - .gitlab/generate-ci/gen_ci.hs - .gitlab/jobs.yaml - compiler/GHC/Cmm/CommonBlockElim.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/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/Solver/Equality.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/conf.py - docs/users_guide/expected-undocumented-flags.txt - docs/users_guide/exts/doandifthenelse.rst - + docs/users_guide/exts/relaxed_poly_rec.rst - docs/users_guide/exts/types.rst - testsuite/tests/default/default-fail05.stderr - testsuite/tests/indexed-types/should_fail/T2693.stderr - testsuite/tests/indexed-types/should_fail/T5439.stderr - + testsuite/tests/numeric/should_compile/T26229.hs - testsuite/tests/numeric/should_compile/all.T - testsuite/tests/parser/should_fail/RecordDotSyntaxFail10.stderr - testsuite/tests/parser/should_fail/RecordDotSyntaxFail11.stderr - + testsuite/tests/partial-sigs/should_compile/T26256.hs - + testsuite/tests/partial-sigs/should_compile/T26256.stderr - testsuite/tests/partial-sigs/should_compile/all.T - 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/T26256a.hs - testsuite/tests/typecheck/should_compile/all.T - 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/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.
