[Git][ghc/ghc][wip/romes/hadrian-cross-stage2-rebase_SVEN_FINAL] 55 commits: Add optional `SrcLoc` to `StackAnnotation` class

Sven Tennie pushed to branch wip/romes/hadrian-cross-stage2-rebase_SVEN_FINAL at Glasgow Haskell Compiler / GHC Commits: 4c40df3d by fendor at 2026-02-20T10:24:48-05:00 Add optional `SrcLoc` to `StackAnnotation` class `StackAnnotation`s give access to an optional `SrcLoc` field that user-added stack annotations can use to provide better backtraces in both error messages and when decoding the callstack. We update builtin stack annotations such as `StringAnnotation` and `ShowAnnotation` to also capture the `SrcLoc` of the current `CallStack` to improve backtraces by default (if stack annotations are used). This change is backwards compatible with GHC 9.14.1. - - - - - fd9aaa28 by Simon Hengel at 2026-02-20T10:25:33-05:00 docs: Fix grammar in explicit_namespaces.rst - - - - - 44354255 by Vo Minh Thu at 2026-02-20T18:53:06-05:00 GHCi: add a :version command.

So we want to avoid other modules depending on it as far as possible. On Windows, the IO manager depends on the RTSFlags type, which transtively depends on MonadFix. We refactor things to avoid this dependency, which would have caused a regression.

However, while the `GHC.Internal.Data.Bool` import was conditional and partial, the `GHC.Internal.Base` import is unconditional and total. As a result, the import list is not tuned to import only the necessary bits anymore, and furthermore GHC emits a lot of warnings about redundant imports. This commit makes the `GHC.Internal.Base` import conditional and partial in the same way that the `GHC.Internal.Data.Bool` import was. - - - - - c951fef1 by Cheng Shao at 2026-02-25T20:58:28+00:00 wasm: add /assets endpoint to serve user-specified assets This patch adds an `/assets` endpoint to the wasm dyld http server, so that users can also fetch assets from the same host with sensible default MIME types, without needing a separate http server for assets that also introduces CORS headaches: - A `-fghci-browser-assets-dir` driver flag is added to specify the assets root directory (defaults to `$PWD`) - The dyld http server fetches `mime-db` on demand and uses it as source of truth for mime types.

This check is currently performed in the renamer: rnHsTyLit tyLit@(HsNumTy x i) = do when (i < 0) $ addErr $ TcRnNegativeNumTypeLiteral tyLit However, this check can be bypassed using RequiredTypeArguments (see the new test case T26861). Prior to this patch, such programs caused the compiler to hang instead of reporting a proper error. This patch addresses the issue by adding an equivalent check in the type checker, namely in tcHsType. The diff is deliberately minimal to facilitate backporting. A more comprehensive rework of HsTyLit is planned for a separate commit. - - - - - faf14e0c by Vladislav Zavialov at 2026-02-27T05:48:45-05:00 Consistent pretty-printing of HsString, HsIsString, HsStrTy Factor out a helper to pretty-print string literals, thus fixing newline handling for overloaded string literals and type literals.

After all, statements are made to be run many times, for instance in ```haskell [u | y <- [0,1], stmts] ``` both `u` and `stmts` are going to be run several times. In principle, though, there are some position in a monad comprehension expression which could be considered linear. We could try and make it so that these positions are considered linear by the typechecker, but in practice the desugarer doesn't take enough care to ensure that these are indeed desugared to linear sites. We tried in the past, and it turned out that we'd miss a desugaring corner case (#25772). Until there's a demand for this very specific improvement, let's instead be conservative, and consider list comprehension to be completely non-linear. - - - - - ae799cab by Simon Jakobi at 2026-02-27T12:53:54-05:00 PmAltConSet: Use Data.Set instead of Data.Map ...to store `PmLit`s.

Additionally, it improves error messages for unsupported type literals, such as unboxed or fractional literals (test cases: T26862, T26862_th). Changes to the AST: * Use HsLit where HsTyLit was previously used * Use HsChar where HsCharTy was previously used * Use HsString where HsStrTy was previously used * Use HsNatural (NEW) where HsNumTy was previously used * Use HsDouble (NEW) to represent unsupported fractional type literals Changes to logic: * Parse unboxed and fractional type literals (to be rejected later) * Drop the check for negative literals in the renamer (rnHsTyLit) in favor of checking in the type checker (tc_hs_lit_ty) * Check for invalid type literals in TH (repTyLit) and report unrepresentable literals with ThUnsupportedTyLit * Allow negative type literals in TH (numTyLit). This is fine as these will be taken care of at splice time (test case: T8306_th) - - - - - c927954f by Vladislav Zavialov at 2026-02-27T18:46:50-05:00 Increase test coverage of diagnostics Add test cases for the previously untested diagnostics: [GHC-01239] PsErrIfInFunAppExpr [GHC-04807] PsErrProcInFunAppExpr [GHC-08195] PsErrInvalidRecordCon [GHC-16863] PsErrUnsupportedBoxedSumPat [GHC-18910] PsErrSemiColonsInCondCmd [GHC-24737] PsErrInvalidWhereBindInPatSynDecl [GHC-25037] PsErrCaseInFunAppExpr [GHC-25078] PsErrPrecedenceOutOfRange [GHC-28021] PsErrRecordSyntaxInPatSynDecl [GHC-35827] TcRnNonOverloadedSpecialisePragma [GHC-40845] PsErrUnpackDataCon [GHC-45106] PsErrInvalidInfixHole [GHC-50396] PsErrInvalidRuleActivationMarker [GHC-63930] MultiWayIfWithoutAlts [GHC-65536] PsErrNoSingleWhereBindInPatSynDecl [GHC-67630] PsErrMDoInFunAppExpr [GHC-70526] PsErrLetCmdInFunAppCmd [GHC-77808] PsErrDoCmdInFunAppCmd [GHC-86934] ClassPE [GHC-90355] PsErrLetInFunAppExpr [GHC-91745] CasesExprWithoutAlts [GHC-92971] PsErrCaseCmdInFunAppCmd [GHC-95644] PsErrBangPatWithoutSpace [GHC-97005] PsErrIfCmdInFunAppCmd Remove unused error constructors: [GHC-44524] PsErrExpectedHyphen [GHC-91382] TcRnIllegalKindSignature - - - - - 3a9470fd by Torsten Schmits at 2026-02-27T18:47:34-05:00 Avoid expensive computation for debug logging in `mergeDatabases` when log level is low This computed and traversed a set intersection for every single dependency unconditionally. - - - - - ea4c2cbd by Brandon Chinn at 2026-02-27T16:22:38-08:00 Implement QualifiedStrings (#26503) See Note [Implementation of QualifiedStrings] - - - - - 08bc245b by sheaf at 2026-03-01T11:11:54-05:00 Clean up join points, casts & ticks This commit shores up the logic dealing with casts and ticks occurring in between a join point binding and a jump. Fixes #26642 #26929 #26693 Makes progress on #14610 #26157 #26422 Changes: - Remove 'GHC.Types.Tickish.TickishScoping' in favour of simpler predicates 'tickishHasNoScope'/'tickishHasSoftScope', as things were before commit 993975d3. This makes the code easier to read and document (fewer indirections). - Introduce 'canCollectArgsThroughTick' for consistent handling of ticks around PrimOps and other 'Id's that cannot be eta-reduced. See overhauled Note [Ticks and mandatory eta expansion]. - New Note [JoinId vs TailCallInfo] in GHC.Core.SimpleOpt that explains robustness of JoinId vs fragility of TailCallInfo. - Allow casts/non-soft-scoped ticks to occur in between a join point binder and a jump, but only in Core Prep. See Note [Join points, casts, and ticks] and Note [Join points, casts, and ticks... in Core Prep] in GHC.Core.Opt.Simplify.Iteration. Also update Core Lint to account for this. See Note [Linting join points with casts or ticks] in GHC.Core.Lint. - Update 'GHC.Core.Utils.mergeCaseAlts' to avoid pushing a cast in between a join point binding and its jumps. This fixes #26642. See the new (MC5) and (MC6) in Note [Merge Nested Cases]. - Update float out to properly handle source note ticks. They are now properly floated out instead of being discarded.

Gillespie at 2026-03-02T10:14:37-05:00 Add SIMD absolute value on x86 and LLVM On x86, absolute value of 32 bits or less is implemented with PABSB/PABSW/PABSD if SSSE3 is available. Otherwise, there is a fallback for SSE2. For 64 bit integers it uses VPABSQ, required by AVX-512VL, with fallbacks for SSE4.2 and SSE2. There is no dedicated instruction for floating point absolute value on x86, so it is simulated using bitwise AND. Absolute value for signed integers and floats are implemented by the "llvm.abs/llvm.fabs" standard library intrinsics. This implementation uses MachOps constructors, unlike non-vector floating point absolute value, which uses CallishMachOps. - - - - - 709448c0 by Sean D.

Therefore we need to persist the choice made at this time into the installation bindist as well so we look for the right tools, with the right prefixes at install time. In the future, we want to provide a bit more control about what kind of bindist we produce so the logic about what the host/target will have to be written by hadrian rather than persisted by the configure script. In particular with cross compilers we want to either build a normal stage 2 cross bindist or a stage 3 bindist, which creates a bindist which has a native compiler for the target platform.
