Apoorv Ingle pushed to branch wip/spj-apporv-Oct24 at Glasgow Haskell Compiler / GHC Commits: 84c3d6b3 by Andreas Klebinger at 2025-05-05T00:23:08-05:00 Expand docs for RTS flag `-M`. The behaviour of how/when exceptions are raised was not really covered in the docs. - - - - - 5ada46a2 by Adam Sandberg Ericsson at 2025-05-05T00:23:08-05:00 add cases for more SchedulerStatus codes in rts_checkSchedStatus - - - - - 41d8bb43 by sheaf at 2025-05-05T00:23:08-05:00 Squash warnings in GHC.Runtime.Heap.Inspect There were incomplete record selector warnings in GHC.Runtime.Heap.Inspect due to the use of the partial 'dataArgs' record selector. This is fixed by passing the fields to the 'extractSubTerms' function directly, rather than passing a value of the parent data type. - - - - - 31d0eb9a by Andreas Klebinger at 2025-05-05T00:23:08-05:00 hadrian: Make ghcWithInterpreter the universal source of truth about availability of the interpreter We were doing some ad-hoc checks in different places in hadrian to determine whether we supported the interprter or not. Now this check if confined to one function, `ghcWithInterpreter`, and all the places which use this information consult `ghcWithInterpreter` to determine what to do. Fixes #25533. - - - - - bdbb7002 by Matthew Pickering at 2025-05-05T00:23:08-05:00 testsuite: Fix running TH tests with profiled dynamic compiler Previously, I had failed to update the ghc_th_way_flags logic for the profiled dynamic compiler. In addition to this `ghc_dynamic` was incorrectly set for profiled dynamic compiler. I also updated MultiLayerModulesTH_OneShot test to work for any compiler linkage rather than just dynamic.

It's therefore up to the user to make sure that the interface file and any relevant artifacts are available for a fixed node. Fixed/Compile nodes are represented by the ModuleNodeInfo type, which abstracts the common parts of Fixed/Compile nodes with accessor functions of type `ModuleNodeInfo -> ...`. Fixed nodes can only depend on other fixed nodes. This invariant can be checked by the function `checkModuleGraph` or `mkModuleGraphChecked`. --make mode is modified to work with fixed mode. In order to "compile" a fixed node, the artifacts are just loaded into the HomePackageTable. Currently nothing in the compiler will produce Fixed nodes but this is tested with the FixedNodes GHC API test. In subsequent patches we are going to remove the ExternalModuleGraph and use Fixed nodes for modules in the module graph in oneshot mode. Fixes #25920 - - - - - 06929a4f by Cheng Shao at 2025-05-05T00:23:08-05:00 ci: remove manual case of ghc-wasm-meta downstream testing jobs This patch removes the manual case of ghc-wasm-meta downstream testing jobs; now the only way of including them in the pipeline and running them is via the test-wasm label. The reason of the removal is it proves to be problematic for MRs with only the wasm label; the wasm job would succeed, then the pipeline status would be waiting for manual action instead of succeeding. There needs to be separate jobs for the label-triggered and manual-triggered cases, but I don't think it's worth that extra complexity, the label-triggered case is already sufficient. - - - - - 8c56c6aa by Vladislav Zavialov at 2025-05-05T00:23:08-05:00 Fix EmptyCase panic in tcMatches (#25960) Due to faulty reasoning in Note [Pattern types for EmptyCase], tcMatches was too keen to panic. * Old (incorrect) assumption: pat_tys is a singleton list. This does not hold when \case{} is checked against a function type preceded by invisible forall. See the new T25960 test case. * New (hopefully correct) assumption: vis_pat_tys is a singleton list.

Consider: x = 42 f, g :: forall a -> ... f (type x) = g x In accordance with the specification, the `g x` function call is renamed as a term, so `x` refers to the top-level binding `x = 42`, not to the type variable binding `type x` as one might expect. This is somewhat counterintuitive because `g` expects a type argument. Forbidding puns in T2T allows us to produce a helpful error message: Test.hs:5:16: error: [GHC-09591] Illegal punned variable occurrence in a required type argument. The name ‘x’ could refer to: ‘x’ defined at Test.hs:3:1 ‘x’ bound at Test.hs:5:9 This commit is a follow up to 0dfb1fa799af254c8a1e1045fc3996af2d57a613 where checking for puns was left as future work. - - - - - 079fbd4c by Vladislav Zavialov at 2025-05-05T00:23:08-05:00 Additional test cases for #12088, #13790 Extract more test cases from ticket discussions, including multi-module examples. Follow up to 5712e0d646f611dfbfedfd7ef6dff3a18c016edb - - - - - 7d40088c by Matthew Pickering at 2025-05-05T00:23:08-05:00 driver: Use ModuleGraph for oneshot and --make mode This patch uses the `hsc_mod_graph` field for both oneshot and --make mode. Therefore, if part of the compiler requires usage of the module graph, you do so in a uniform way for the two different modes. The `ModuleGraph` describes the relationship between the modules in the home package and units in external packages. The `ModuleGraph` can be queried when information about the transitive closure of a package is needed. For example, the primary use of the ModuleGraph from within the compiler is in the loader, which needs to know the transitive closure of a module so it can load all the relevant objects for evaluation. In --make mode, downsweep computes the ModuleGraph before any compilation starts. In oneshot mode, a thunk is created at the start of compilation, which when forced will compute the module graph beneath the current module. The thunk is only forced at the moment when the user uses Template Haskell. Finally, there are some situations where we need to discover what dependencies to load but haven't loaded a module graph at all. In this case, there is a fallback which computes the transitive closure on the fly and doesn't cache the result. Presumably if you are going to call getLinkDeps a lot, you would compute the right ModuleGraph before you started. Importantly, this removes the ExternalModuleGraph abstraction. This was quite awkward to work with since it stored information about the home package inside the EPS. This patch will also be very useful when implementing explicit level imports, which requires more significant use of the module graph in order to determine which level instances are available at.

According to the exportable-named-default proposal (sections 2.4.2 and 2.4.3), local defaults should be merged into tcg_default, retaining any defaults already present while overriding where necessary. Key Changes: * Introduce DefaultProvenance to track the origin of default declarations (local, imported, or built-in), replacing the original cd_module in ClassDefaults with cd_provenance :: DefaultProvenance. * Rename tcDefaults to tcDefaultDecls, limiting its responsibility to only converting renamed class defaults into ClassDefaults. * Add extendDefaultEnvWithLocalDefaults to merge local defaults into the environment, with proper duplication checks: - Duplicate local defaults for a class trigger an error. - Local defaults override imported or built-in defaults. * Update and add related notes: Note [Builtin class defaults], Note [DefaultProvenance]. * Add regression tests: T25912, T25914, T25934. Thanks sam and simon for the help on this patch.

They have no usages on Hackage.

We also fix the host info displayed by "+RTS --info": the host of the RTS is the RTS-building compiler's target, not the compiler's host (wrong when doing cross-compilation). - - - - - ebab872b by Sylvain Henry at 2025-05-05T00:23:08-05:00 RTS: remove build info As per the discussion in !13967, there is no reason to tag the RTS with information about the build platform. - - - - - 8b1dd80e by Vladislav Zavialov at 2025-05-05T00:23:08-05:00 Diagnostics: remove the KindMismatch constructor (#25957) The KindMismatch constructor was only used as an intermediate representation in pretty-printing. Its removal addresses a problem detected by the "codes" test case: [GHC-89223] is untested (constructor = KindMismatch) In a concious deviation from the usual procedure, the error code GHC-89223 is removed entirely rather than marked as Outdated. The reason is that it never was user-facing in the first place. - - - - - f8f64c35 by Vladislav Zavialov at 2025-05-05T00:23:09-05:00 Add name for -Wunusable-unpack-pragmas This warning had no name or flag and was triggered unconditionally. Now it is part of -Wdefault. In GHC.Tc.TyCl.tcTyClGroupsPass's strict mode, we now have to force-enable this warning to ensure that detection of flawed groups continues to work even if the user disables the warning with the -Wno-unusable-unpack-pragmas option. Test case: T3990c Also, the misnamed BackpackUnpackAbstractType is now called UnusableUnpackPragma. - - - - - fb64e6b8 by Adam Gundry at 2025-05-05T00:23:09-05:00 Fix specialisation of incoherent instances (fixes #25883) GHC normally assumes that class constraints are canonical, meaning that the specialiser is allowed to replace one dictionary argument with another provided that they have the same type. The `-fno-specialise-incoherents` flag alters INCOHERENT instance definitions so that they will prevent specialisation in some cases, by inserting `nospec`. This commit fixes a bug in 7124e4ad76d98f1fc246ada4fd7bf64413ff2f2e, which treated some INCOHERENT instance matches as if `-fno-specialise-incoherents` was in effect, thereby unnecessarily preventing specialisation. In addition it updates the relevant `Note [Rules for instance lookup]` and adds a new `Note [Canonicity for incoherent matches]`. - - - - - 3dde2ba2 by Adam Gundry at 2025-05-05T00:23:09-05:00 Add regression test for #23429 - - - - - 032e0662 by Adam Gundry at 2025-05-05T00:23:09-05:00 user's guide: update specification of overlapping/incoherent instances The description of the instance resolution algorithm in the user's guide was slightly out of date, because it mentioned in-scope given constraints only at the end, whereas the implementation checks for their presence before any of the other steps. This also adds a warning to the user's guide about the impact of incoherent instances on specialisation, and more clearly documents some of the other effects of `-XIncoherentInstances`. - - - - - 2d87c26b by Matthew Craven at 2025-05-05T00:23:09-05:00 Fix bytecode generation for `tagToEnum# <LITERAL>` Fixes #25975. - - - - - 7e6a0f17 by Andreas Klebinger at 2025-05-05T00:23:09-05:00 Simplifier: Constant fold invald tagToEnum# calls to bottom expr. When applying tagToEnum# to a out-of-range value it's best to simply constant fold it to a bottom expression. That potentially allows more dead code elimination and makes debugging easier.

The modules in `ImpDeclSpec` have already been resolved to the actual module to get the information from during renaming. Therefore we just need to fetch the precise interface from disk (and not attempt to rename it again).

This `EvalBreakpoint` needs to be converted to an `InternalBreakpointId` which stores a `Module` to uniquely find the correct `Module` in the Home Package Table. The `EvalBreakpoint` used to store only a `ModuleName` which is then converted to a `Module` based on the currently active home unit. This is incorrect in the face of multiple home units, the break point could be in an entirely other home unit! To fix this, we additionally store the `UnitId` of the `Module` in `EvalBreakpoint` to later reconstruct the correct `Module` All of the changes are the consequence of extending `EvalBreakpoint` with the additional `ShortByteString` of the `UnitId`. For performance reasons, we store the `ShortByteString` backing the `UnitId` directly, avoiding marshalling overhead. - - - - - e8fd6740 by Sylvain Henry at 2025-05-05T00:23:09-05:00 Doc: add doc for JS interruptible calling convention (#24444) - - - - - 371c49a7 by Ben Gamari at 2025-05-05T00:23:09-05:00 compiler: Ensure that Panic.Plain.assertPanic' provides callstack In 36cddd2ce1a3bc62ea8a1307d8bc6006d54109cf @alt-romes removed CallStack output from `GHC.Utils.Panic.Plain.assertPanic'`. While this output is redundant due to the exception backtrace proposal, we may be bootstrapping with a compiler which does not yet include this machinery. Reintroduce the output for now. Fixes #25898. - - - - - 8f99063c by Matthew Pickering at 2025-05-05T00:23:09-05:00 Implement Explicit Level Imports for Template Haskell This commit introduces the `ExplicitLevelImports` and `ImplicitStagePersistence` language extensions as proposed in GHC Proposal #682. Key Features ------------ - `ExplicitLevelImports` adds two new import modifiers - `splice` and `quote` - allowing precise control over the level at which imported identifiers are available - `ImplicitStagePersistence` (enabled by default) preserves existing path-based cross-stage persistence behavior - `NoImplicitStagePersistence` disables implicit cross-stage persistence, requiring explicit level imports Benefits -------- - Improved compilation performance by reducing unnecessary code generation - Enhanced IDE experience with faster feedback in `-fno-code` mode - Better dependency tracking by distinguishing compile-time and runtime dependencies - Foundation for future cross-compilation improvements This implementation enables the separation of modules needed at compile-time from those needed at runtime, allowing for more efficient compilation pipelines and clearer code organization in projects using Template Haskell. Implementation Notes -------------------- The level which a name is availble at is stored in the 'GRE', in the normal GlobalRdrEnv. The function `greLevels` returns the levels which a specific GRE is imported at. The level information for a 'Name' is computed by `getCurrentAndBindLevel`. The level validity is checked by `checkCrossLevelLifting`. Instances are checked by `checkWellLevelledDFun`, which computes the level an instance by calling `checkWellLevelledInstanceWhat`, which sees what is available at by looking at the module graph. Modifications to downsweep -------------------------- Code generation is now only enabled for modules which are needed at compile time. See the Note [-fno-code mode] for more information. Uniform error messages for level errors --------------------------------------- All error messages to do with levels are now reported uniformly using the `TcRnBadlyStaged` constructor. Error messages are uniformly reported in terms of levels. 0 - top-level 1 - quote level -1 - splice level The only level hard-coded into the compiler is the top-level in GHC.Types.ThLevelIndex.topLevelIndex. Uniformly refer to levels and stages ------------------------------------ There was much confusion about levels vs stages in the compiler. A level is a semantic concept, used by the typechecker to ensure a program can be evaluated in a well-staged manner. A stage is an operational construct, program evaluation proceeds in stages. Deprecate -Wbadly-staged-types ------------------------------ `-Wbadly-staged-types` is deprecated in favour of `-Wbadly-levelled-types`. Lift derivation changed ----------------------- Derived lift instances will now not generate code with expression quotations. Before: ``` data A = A Int deriving Lift => lift (A x) = [| A $(lift x) |] ``` After: ``` lift (A x) = conE 'A `appE` (lift x) ``` This is because if you attempt to derive `Lift` in a module where `NoImplicitStagePersistence` is enabled, you would get an infinite loop where a constructor was attempted to be persisted using the instance you are currently defining. GHC API Changes --------------- The ModuleGraph now contains additional information about the type of the edges (normal, quote or splice) between modules. This is abstracted using the `ModuleGraphEdge` data type.

(It might be nested.) This small MR fixes #25995. It's a tiny fix, to an error message, removing an always-dubious `unkSkol`. The bug report was in the context of horde-ad, a big program, and I didn't manage to make a small repro case quickly. I decided not to bother further. - - - - - 7051648f by Apoorv Ingle at 2025-05-05T00:23:09-05:00 exception for AppDo while making error ctxt - - - - - 8efcd856 by Apoorv Ingle at 2025-05-05T00:23:09-05:00 moving around things for locations and error ctxts -
