Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: 5bd6a964 by Rodrigo Mesquita at 2026-04-30T04:54:08-04:00 New rts Message to {set,unset} TSO flags This commit introduces stg_MSG_SET_TSO_FLAG_info and stg_MSG_UNSET_TSO_FLAG_info, which allows setting flags of a TSO other than yourself. This is especially useful/necessary to set breakpoints and toggle breakpoints of different threads, which is needed to safely implement features like pausing, toggling step-out, toggling step-in per thread, etc. Fixes #27131 ------------------------- Metric Decrease: T3294 ------------------------- - - - - - ce97fd3e by Rodrigo Mesquita at 2026-04-30T04:54:08-04:00 test: Add test setting another TSO's flags Introduces a test that runs on two capabilities. The main thread running on Capability 0 sets the flags on a TSO running on Capability 1. The TSO from Capability 1 itself checks whether its flags were set and reports that back. This validates that the RTS messages for setting TSO flags work, even if it doesn't test a harsher scenario with race conditions to exercise why the message passing is necessary for safely setting another TSO's flags.

Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: d59b7c71 by Wolfgang Jeltsch at 2026-04-30T04:53:25-04:00 Move code that uses `GHC.Internal.Text.Read` into `base` This contribution serves to remove all dependencies on `GHC.Internal.Text.Read` from within `ghc-internal`, so that the implementation of `Text.Read` and ultimately more reading-related code can be moved to `base` as well. The following things are moved from `ghc-internal` to `base`: * I/O-related `Read` instances * Most of the `Numeric` implementation * The instance `Read ByteOrder` * The `parseVersion` operation * The `readConstr` operation Metric Increase: LinkableUsage01 T9198 T12425 T13035 T13820 T18140 - - - - - 21 changed files: - libraries/base/src/Data/Data.hs - libraries/base/src/Data/Version.hs - libraries/base/src/GHC/ByteOrder.hs - libraries/base/src/Numeric.hs - libraries/base/src/System/IO.hs - libraries/base/src/Text/Printf.hs - libraries/ghc-internal/src/GHC/Internal/Data/Data.hs - libraries/ghc-internal/src/GHC/Internal/Data/Version.hs - libraries/ghc-internal/src/GHC/Internal/IO/Device.hs - libraries/ghc-internal/src/GHC/Internal/IO/Handle/Types.hs - libraries/ghc-internal/src/GHC/Internal/IO/IOMode.hs - libraries/ghc-internal/src/GHC/Internal/Numeric.hs - libraries/ghc-internal/src/GHC/Internal/Read.hs - testsuite/tests/interface-stability/base-exports.stdout - testsuite/tests/interface-stability/base-exports.stdout-javascript-unknown-ghcjs - testsuite/tests/interface-stability/base-exports.stdout-mingw32 - testsuite/tests/interface-stability/base-exports.stdout-ws-32 - testsuite/tests/plugins/plugins09.stdout - testsuite/tests/plugins/plugins10.stdout - testsuite/tests/plugins/plugins11.stdout - testsuite/tests/plugins/static-plugins.stdout Changes: ===================================== libraries/base/src/Data/Data.hs ===================================== @@ -99,3 +99,38 @@ module Data.Data ( import GHC.Internal.Data.Data import Data.Typeable + +import GHC.Real (toRational) +import GHC.Float (Double) +import Data.Eq ((==)) +import Data.Function ((.)) +import Data.Maybe (Maybe (Nothing, Just)) +import Data.List (filter) +import Data.String (String) +import Text.Read (Read, reads) + +-- | Lookup a constructor via a string +readConstr :: DataType -> String -> Maybe Constr +readConstr dt str = + case dataTypeRep dt of + AlgRep cons -> idx cons + IntRep -> mkReadCon (\i -> (mkPrimCon dt str (IntConstr i))) + FloatRep -> mkReadCon ffloat + CharRep -> mkReadCon (\c -> (mkPrimCon dt str (CharConstr c))) + NoRep -> Nothing + where + + -- Read a value and build a constructor + mkReadCon :: Read t => (t -> Constr) -> Maybe Constr + mkReadCon f = case (reads str) of + [(t,"")] -> Just (f t) + _ -> Nothing + + -- Traverse list of algebraic datatype constructors + idx :: [Constr] -> Maybe Constr + idx cons = case filter ((==) str . showConstr) cons of + [] -> Nothing + hd : _ -> Just hd + + ffloat :: Double -> Constr + ffloat = mkPrimCon dt str .

[Git][ghc/ghc][master] 7 commits: Make cmm 'import "package" name;' syntax use consistent label types
by Marge Bot (＠marge-bot) 30 Apr '26

Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: 9f85f034 by Duncan Coutts at 2026-04-30T04:52:42-04:00 Make cmm 'import "package" name;' syntax use consistent label types There is a little-used syntactic form in cmm imports: import "package" foo; Which means to import foo from the given package (unit id, specified as a string). This syntax is somewhat reminiscent of GHC's package import extension. This syntax form is not used in the rts cmm code, nor any of the boot libraries. It may not be used at all. Unclear. Change the kind of CLabel this syntax generates to be consistent with the others. The other cmm imports use ForeignLabel with ForeignLabelInExternalPackage. For some reason this form was using CmmLabel. Change that to also be ForeignLabel but with ForeignLabelInPackage. This specifies a specific package, rather than an unnamed external package. - - - - - a811f68f by Duncan Coutts at 2026-04-30T04:52:42-04:00 Change default cmm import statements to be internal Previously a cmm statement like: import foo; meant to expect the symbol from a different shared library than the current one. Now it means to expect the symbol from the same shared library as the current one. We'll add explicit syntax to indicate that it's a foreign import. Most existing uses are in fact intenal (rts to rts), so few imports will need to be annotated foreign. Examples would include cmm code in libraries (other than the rts) that need to access RTS APIs. In practice, this makes no difference whatsoever at the moment on any platform other than windows (where building Haskell libs as shared libs does not fully work yet), since the 'labelDynamic' treats all such labels as foreign, irrespective of the foreign label source. - - - - - 17fe5d1d by Duncan Coutts at 2026-04-30T04:52:42-04:00 Add cmm import syntax 'import DATA foo;' as better name for CLOSURE The existing syntax is: import CLOSURE foo; The new syntax is import DATA foo; This means to interpret the symbol foo as refering to data (i.e. a global constant or variable) rather than to code (a function). The historical syntax for this uses CLOSURE, which is rather misleading. Presumably this was done to avoid introducing new reserved words. Be less squemish about new reserved words and add DATA and use that. Keep the existing CLOSURE syntax as an alias for compatibility. - - - - - 3a530d68 by Duncan Coutts at 2026-04-30T04:52:42-04:00 Add cmm 'import extern name;' syntax Since the default for cmm imports is now for symbols within the same shared object, we need a way to indicate we want a symbol from an external shared object: import extern foo; -- for a function import extern DATA foo; -- for data This adds a new reserved word 'extern'. We don't expect to have to use this much. Most cmm imports are intra-DSO. This makes no difference currently on ELF and MachO platforms, but does make a difference to the linking conventions on PE (Windows). In future it's plausible we could take make distinctions on ELF or MachO, so it's worth trying to get it right.

[Git][ghc/ghc][wip/fendor/T27202] 3 commits: Introduce a cache of home module name providers
by Hannes Siebenhandl (＠fendor) 30 Apr '26

30 Apr '26

Hannes Siebenhandl pushed to branch wip/fendor/T27202 at Glasgow Haskell Compiler / GHC Commits: bc36279c by Wolfgang Jeltsch at 2026-04-30T09:38:31+02:00 Introduce a cache of home module name providers This contribution introduces to the module graph a cache that maps home module names to sets of units providing them and changes the finder to use that cache. This is a performance optimization, especially for multi-home-unit builds. The particular changes are as follows: * In `GHC.Unit.Module.Graph`, `ModuleGraph` is extended with a new field `mg_home_module_name_providers_map`, exposed as `mgHomeModuleNameProvidersMap`. This is a cache that assigns to each home module name the set of IDs of home units that define it. Operations that construct module graphs are updated such that this cache stays synchronized. * In `GHC.Unit.Finder`, `findImportedModule` is changed to pull `mgHomeModuleNameProvidersMap` from `hsc_mod_graph` and pass it to `findImportedModuleNoHsc`, which now does not search home units in arbitrary order but prioritizes those units that the cache mentions as potential providers of the requested module. Resolves #27055.

[Git][ghc/ghc][wip/marge_bot_batch_merge_job] 15 commits: Make cmm 'import "package" name;' syntax use consistent label types
by Marge Bot (＠marge-bot) 30 Apr '26

30 Apr '26

Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 10aec92b by Duncan Coutts at 2026-04-29T22:12:02-04:00 Make cmm 'import "package" name;' syntax use consistent label types There is a little-used syntactic form in cmm imports: import "package" foo; Which means to import foo from the given package (unit id, specified as a string). This syntax is somewhat reminiscent of GHC's package import extension. This syntax form is not used in the rts cmm code, nor any of the boot libraries. It may not be used at all. Unclear. Change the kind of CLabel this syntax generates to be consistent with the others. The other cmm imports use ForeignLabel with ForeignLabelInExternalPackage. For some reason this form was using CmmLabel. Change that to also be ForeignLabel but with ForeignLabelInPackage. This specifies a specific package, rather than an unnamed external package. - - - - - ffd884d5 by Duncan Coutts at 2026-04-29T22:12:02-04:00 Change default cmm import statements to be internal Previously a cmm statement like: import foo; meant to expect the symbol from a different shared library than the current one. Now it means to expect the symbol from the same shared library as the current one. We'll add explicit syntax to indicate that it's a foreign import. Most existing uses are in fact intenal (rts to rts), so few imports will need to be annotated foreign. Examples would include cmm code in libraries (other than the rts) that need to access RTS APIs. In practice, this makes no difference whatsoever at the moment on any platform other than windows (where building Haskell libs as shared libs does not fully work yet), since the 'labelDynamic' treats all such labels as foreign, irrespective of the foreign label source. - - - - - e37a298a by Duncan Coutts at 2026-04-29T22:12:02-04:00 Add cmm import syntax 'import DATA foo;' as better name for CLOSURE The existing syntax is: import CLOSURE foo; The new syntax is import DATA foo; This means to interpret the symbol foo as refering to data (i.e. a global constant or variable) rather than to code (a function). The historical syntax for this uses CLOSURE, which is rather misleading. Presumably this was done to avoid introducing new reserved words. Be less squemish about new reserved words and add DATA and use that. Keep the existing CLOSURE syntax as an alias for compatibility. - - - - - 9d6ee0c5 by Duncan Coutts at 2026-04-29T22:12:03-04:00 Add cmm 'import extern name;' syntax Since the default for cmm imports is now for symbols within the same shared object, we need a way to indicate we want a symbol from an external shared object: import extern foo; -- for a function import extern DATA foo; -- for data This adds a new reserved word 'extern'. We don't expect to have to use this much. Most cmm imports are intra-DSO. This makes no difference currently on ELF and MachO platforms, but does make a difference to the linking conventions on PE (Windows). In future it's plausible we could take make distinctions on ELF or MachO, so it's worth trying to get it right. Windows can be the guinea pig. - - - - - 59fcd3b3 by Duncan Coutts at 2026-04-29T22:12:03-04:00 Add cmm syntax 'import "package" DATA foo;' for completeness We already have: import DATA foo; -- for data imports import "package" foo; -- for imports from a given unitid There's no reason not to have both at once: import "package" DATA foo; So add that. - - - - - ffadb3cf by Duncan Coutts at 2026-04-29T22:12:03-04:00 Improve the commentary for the cmm import grammar.

[Git][ghc/ghc][wip/marge_bot_batch_merge_job] 12 commits: Make cmm 'import "package" name;' syntax use consistent label types
by Marge Bot (＠marge-bot) 29 Apr '26

29 Apr '26

Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 32d25516 by Duncan Coutts at 2026-04-29T15:50:25-04:00 Make cmm 'import "package" name;' syntax use consistent label types There is a little-used syntactic form in cmm imports: import "package" foo; Which means to import foo from the given package (unit id, specified as a string). This syntax is somewhat reminiscent of GHC's package import extension. This syntax form is not used in the rts cmm code, nor any of the boot libraries. It may not be used at all. Unclear. Change the kind of CLabel this syntax generates to be consistent with the others. The other cmm imports use ForeignLabel with ForeignLabelInExternalPackage. For some reason this form was using CmmLabel. Change that to also be ForeignLabel but with ForeignLabelInPackage. This specifies a specific package, rather than an unnamed external package. - - - - - 8f849ab9 by Duncan Coutts at 2026-04-29T15:50:25-04:00 Change default cmm import statements to be internal Previously a cmm statement like: import foo; meant to expect the symbol from a different shared library than the current one. Now it means to expect the symbol from the same shared library as the current one. We'll add explicit syntax to indicate that it's a foreign import. Most existing uses are in fact intenal (rts to rts), so few imports will need to be annotated foreign. Examples would include cmm code in libraries (other than the rts) that need to access RTS APIs. In practice, this makes no difference whatsoever at the moment on any platform other than windows (where building Haskell libs as shared libs does not fully work yet), since the 'labelDynamic' treats all such labels as foreign, irrespective of the foreign label source. - - - - - 3927dff2 by Duncan Coutts at 2026-04-29T15:50:25-04:00 Add cmm import syntax 'import DATA foo;' as better name for CLOSURE The existing syntax is: import CLOSURE foo; The new syntax is import DATA foo; This means to interpret the symbol foo as refering to data (i.e. a global constant or variable) rather than to code (a function). The historical syntax for this uses CLOSURE, which is rather misleading. Presumably this was done to avoid introducing new reserved words. Be less squemish about new reserved words and add DATA and use that. Keep the existing CLOSURE syntax as an alias for compatibility. - - - - - cad4d44c by Duncan Coutts at 2026-04-29T15:50:25-04:00 Add cmm 'import extern name;' syntax Since the default for cmm imports is now for symbols within the same shared object, we need a way to indicate we want a symbol from an external shared object: import extern foo; -- for a function import extern DATA foo; -- for data This adds a new reserved word 'extern'. We don't expect to have to use this much. Most cmm imports are intra-DSO. This makes no difference currently on ELF and MachO platforms, but does make a difference to the linking conventions on PE (Windows). In future it's plausible we could take make distinctions on ELF or MachO, so it's worth trying to get it right. Windows can be the guinea pig. - - - - - 9bdca0ee by Duncan Coutts at 2026-04-29T15:50:25-04:00 Add cmm syntax 'import "package" DATA foo;' for completeness We already have: import DATA foo; -- for data imports import "package" foo; -- for imports from a given unitid There's no reason not to have both at once: import "package" DATA foo; So add that. - - - - - 9c4c5aaf by Duncan Coutts at 2026-04-29T15:50:25-04:00 Improve the commentary for the cmm import grammar.

Experiments with dynamic linking the ghc-internal library yielded a link command well over 32kb.

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).

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.

This is about reducing the number of exported top level names and unfoldings, which reduces interface file sizes and reduces the number of global/dynamic linker symbols. Also accept the changed test output and metric decreases. Tests that record the phase output for type checking or for simplifier end up with different output: the generated bindings now have an Inline [~] annotation, and many top level names are now local rather than module-prefixed for export. Also accept the numerous metric decreases in compile_time/bytes allocated, and a few in compile_time/max_bytes_used. There's also one instance of a decrease in runtime/max_bytes_used but it's a ghci-way test and so presumably the reason is that it loads smaller .hi files and/or links fewer symbols. ------------------------- Metric Decrease: CoOpt_Singletons MultiLayerModulesTH_OneShot MultilineStringsPerf T10421 T10547 T12150 T12227 T12234 T12425 T13035 T13056 T13253 T13253-spj T15304 T15703 T16875 T17836b T17977b T18140 T18223 T18282 T18304 T18698a T18698b T18730 T18923 T20049 T21839c T24471 T24582 T24984 T3064 T4029 T5030 T5642 T5837 T6048 T9020 T9198 T9961 TcPlugin_RewritePerf WWRec hard_hole_fits mhu-perf ------------------------- - - - - - 67df5161 by Duncan Coutts at 2026-03-09T12:08:35-04:00 Add documentation Note [NOINLINE on generated Typeable bindings] and refer to it from the code and existing documentation. - - - - - c4ad6167 by Duncan Coutts at 2026-03-09T12:08:35-04:00 Switch existing note to "named wrinkle" style, (GPT1)..(GPT7) GPT = Grand plan for Typeable - - - - - dc84f8e2 by Cheng Shao at 2026-03-09T12:09:21-04:00 ci: only build deb13 for validate pipeline aarch64-linux jobs This patch drops the redundant aarch64-linux deb12 job from validate pipelines and only keeps deb13; it's still built in nightly/release pipelines.

If the optimised RHS discarded uses of an argument that the stable unfolding still needed, it would be incorrectly marked absent. Worker/wrapper would then replace it with LitRubbish, and inlining the stable unfolding would use the rubbish value, causing a segfault. To fix, we introduce addUnfoldingDemands which analyses the stable unfolding with dmdAnal and combines its DmdType with the RHS's via the new `maxDmdType` which combines the demands of the stable unfolding with the rhs, so we can avoid any situation where we give an absent demand to something which is still used by the stable unfolding.

This wrapper prevented GHC from recognising the result as a static StgRhsCon, causing top-level closures to be allocated as thunks instead of being statically allocated. Fix: try to perform the numeric literal cast at compile time using mkLitNumberWrap (wrapping semantics). If successful, return the cast literal directly with an identity wrapper (no case expression). The runtime cast path is kept as fallback for non-literal arguments.

The test constructs a stale package dependency on purpose. `pkgB` is compiled against one version of package `A`, then the same unit id is replaced by an incompatible build of `A`. When `Main` imports `B`, GHC has to read `B.hi`, finds an unfolding that still mentions the old `A`, and should fail while loading interfaces. Closes #2057.

In the desugarer, when we see a record selector or an occurrence of 'getField'. Here, we can use pattern matching information to ensure we don't give false positives. 2. In the typechecker, which might sometimes give false positives but can emit warnings in cases that the pattern match checker would otherwise miss. This is explained in Note [Detecting incomplete record selectors] in GHC.HsToCore.Pmc. Now, we obviously don't want to emit the same error twice, and generally we prefer (1), as those messages contain fewer false positives. So we suppress (2) when we are sure we are going to emit (1); the logic for doing so is in GHC.Tc.Instance.Class.warnIncompleteRecSel, and works by looking at the CtOrigin. Now, the issue was that this logic handled explicit record selectors as well as overloaded record field selectors such as "x.r" (which turns into a simple GetFieldOrigin CtOrigin), but it didn't properly handle record projectors like ".fld" or ".fld1.fld2" (which result in other CtOrigins such as 'RecordFieldProjectionOrigin'). To solve this problem, we re-use the 'isHasFieldOrigin' introduced in fbdc623a (slightly adjusted). On the way, we also had to update the desugarer with special handling for the 'ExpandedThingTc' case in 'ds_app', to make sure that 'ds_app_var' sees all the type arguments to 'getField' in order for it to indeed emit warnings like in (1).

The Rational type is deficient for this purpose, dealing poorly with NaN, +/-Infinity, and negative zero. Instead, the new module GHC.Types.Literal.Floating uses the host Float/Double type to represent NaNs, infinities and negative zero. It also contains a Rational constructor, for the benefit of -fexcess-precision. Other changes: - Remove Note [negative zero] and related code This also removes the restrictions on constant-folding of division by zero, and should make any problems with NaN/Infinity more obvious. - Use -0.0 as the additive identity for Core constant folding rules for floating-point addition, fixing #21227. - Manual worker-wrapper for GHC.Float.rationalToDouble. This is intended to prevent the compiler's WW on this function from interfering with constant-folding. This change means that we now avoid allocating a box for the result of a 'realToFrac' call in T10359. - Combine floatDecodeOp and doubleDecodeOp. This change also fixes a bug in doubleDecodeOp wherein it would incorrectly produce an Int# instead of an Int64# literal for the mantissa component with 64-bit targets. - Use Float/Double for assembly immediates, and update the X86 and PowerPC backends to properly handle special values such as NaN and infinity. - Allow 'rational_to' to handle zero denominators, fixing a TODO in GHC.Core.Opt.ConstantFold.

Our analysis is more powerful and handles type conversions: e.g. word8ToWord x <= 255 is now detected as always True too.

If the stack is not sufficiently aligned, LLVM inserts a realignment prologue that reserves %rbp as a frame pointer, conflicting with GHC's use of %rbp as an STG callee-saved register and breaking the tail-call-based calling convention. Previously, GHC worked around this by lying to LLVM about the stack alignment and rewriting aligned vector loads/stores (VMOVDQA, VMOVAPS) to unaligned ones (VMOVDQU, VMOVUPS) in the LLVM Mangler. This had two problems: - It did not extend to AVX-512, which requires 64-byte alignment. (#26595) - When Haskell calls a C function that takes __m256/__m512 arguments on the stack, the callee requires genuine alignment, which could cause a segfault. (#26822) This patch genuinely aligns the stack to 64 bytes in StgRun by saving the original stack pointer before alignment and restoring it in StgReturn. We now unconditionally advertise 64-byte stack alignment to LLVM for all x86 targets, making rewriteAVX in the LLVM Mangler unnecessary. STG_RUN_STACK_FRAME_SIZE is increased from 48 to 56 bytes on non-Windows x86-64 to store the saved stack pointer.

GHC.Internal.Generics used to be in the middle of the module graph, but now it is nearer the top (built later). This change thins out the module graph and allows us to get rid of the ByteOrder hs-boot file. We implement this by moving Generics instances from the module where the datatype is defined to the GHC.Internal.Generics module. This trades off increasing the compiled size of GHC.Internal.Generics with reducing the dependency footprint of datatype modules. Not all instances are moved to GHC.Internal.Generics. For instance, `GHC.Internal.Control.Monad.Fix` keeps its instance as it is one of the very last modules compiled in `ghc-internal` and so inverting the relationship here would risk adding GHC.Internal.Generics back onto the critical path. We also don't change modules that are re-exported from the `template-haskell` or `ghc-heap`. This is done to make it easy to eventually move `Generics` to `base` once something like #26657 is implemented.

This is not always true: the TSO can migrate before the inbox entry is handled. When that happened, handleCloneStackMessage could clone a live stack from the wrong capability and use the wrong capability for allocation and performTryPutMVar, leading to stack sanity failures such as checkStackFrame: weird activation record found on stack. Fix this by passing the current capability into handleCloneStackMessage, rechecking msg->tso->cap at handling time, and forwarding the message if the TSO has migrated. Once ownership matches, use the executing capability consistently for cloneStack, rts_apply, and performTryPutMVar.

This commit changes `flushEventLog` to acquire/release the `state_change` mutex to prevent interleaving with `startEventLogging` and `endEventLogging`. In the current RTS, `flushEventLog` _does not_ acquire this mutex, which may lead to eventlog corruption on the following interleaving: - `startEventLogging` writes the new `EventLogWriter` to `event_log_writer`. - `flushEventLog` flushes some events to `event_log_writer`. - `startEventLogging` writes the eventlog header to `event_log_writer`. This causes the eventlog to be written out in an unreadable state, with one or more events preceding the eventlog header. This commit renames the old function to `flushEventLog_` and defines `flushEventLog` simply as: ```c void flushEventLog(Capability **cap USED_IF_THREADS) { ACQUIRE_LOCK(&state_change_mutex); flushEventLog_(cap); RELEASE_LOCK(&state_change_mutex); } ``` The old function is still needed internally within the compilation unit, where it is used in `endEventLogging` in a context where the `state_change` mutex has already been acquired. I've chosen to mark `flushEventLog_` as static and let other uses of `flushEventLog` within the RTS refer to the new version. There is one use in `hs_init_ghc` via `flushTrace`, where the new locking behaviour should be harmless, and one use in `handle_tick`, which I believe was likely vulnerable to the same race condition, so the new locking behaviour is desirable. I have not added a test. The behaviour is highly non-deterministic and requires a program that concurrently calls `flushEventLog` and `startEventLogging`/`endEventLogging`. I encountered the issue while developing `eventlog-socket` and within that context have verified that my patch likely addresses the issue: a test that used to fail within the first dozen or so runs now has been running on repeat for several hours. - - - - - 7b9a75f0 by Phil Hazelden at 2026-03-26T03:58:37-04:00 Fix build with werror on glibc 2.43.

For example: {-# LANGUAGE RequiredTypeArguments, StarIsType #-} x1 = f (* -> * -> *) x2 = f (forall k. k -> *) x3 = f ((* -> *) -> Constraint) Summary of the changes: * Introduce the HsStar constructor of HsExpr and its extension field XStar. It is analogous to HsStarTy in HsType. * Refactor HsStarTy to store the unicode flag as TokStar, defined as type TokStar = EpUniToken "*" "★" -- similar to TokForall, TokRArrow, etc. The token is stored in the extension field and replaces the Bool field. * Extend the `infixexp2` nonterminal to parse `*` as a direct argument of `->`.

This slot would be filled by the IO manager upon completion of the async call. However, if the blocked thread was interrupted by an async exception, we would end up in an invalid state: - If the blocked computation was never re-entered, the StgAsyncIOResult would never be freed. - If the blocked computation was re-entered, the thread would find an unitialized stack slot for the StgAsyncIOResult, leading to a crash reading its fields, or freeing the pointer.

This is fixed by using 'splitFunTys'. - The 'ExplicitTuple' case failed to take into account tuple sections, and was also incorrectly handling 1-tuples (e.g. 'Solo') which can be constructed using Template Haskell. - The 'NegApp' case was returning the type of the negation operator, again failing to apply it to the argument. Fixed by using 'funResultTy'. - The 'HsProc' case was computing the result type of the arrow proc block, without taking into account the argument type. Fix that by adding a new field to 'CmdTopTc' that stores the arrow type, so that we can construct the correct result type `arr a b` for `proc (pat :: a) -> (cmd :: b)`. - The 'ArithSeq' and 'NegApp' cases were failing to take into account the result 'HsWrapper', which could e.g. silently drop casts. This is fixed by introducing 'syntaxExpr_wrappedFunResTy' which, on top of taking the result type, applies the result 'HsWrapper'. These fixes are validated by the new GHC API test T26910.

User-facing changes: 1. Infix holes (t1 `_` t2) are now permitted in types, following the precedent set by term-level expressions. Test case: T11107 2. Error messages for illegal promotion ticks are now reported at more precise source locations. Test case: T17865 Internal changes: * The definition of HsOpTy now mirrors that of OpApp: | HsOpTy (XOpTy p) (LHsType p) (LHsType p) (LHsType p) | OpApp (XOpApp p) (LHsExpr p) (LHsExpr p) (LHsExpr p) This moves us one step closer to unifying HsType and HsExpr. * Ignoring locations, the old pattern match (HsOpTy x prom lhs op rhs) is now written as (HsOpTy x lhs (HsTyVar x' prom op) rhs) but we also handle (HsOpTy x lhs (HsWildCardTy x') rhs) Constructors other than HsTyVar and HsWildCardTy never appear in the operator position. * The various definitions across the compiler have been updated to work with the new representation, drawing inspiration from the term-level pipeline where appropriate.

This starts accumulating a lot of `UnlinkedBCO` and memory over time. However, the `Linkable` is merely used to later record its usage in `mkObjectUsage`, which is used for recompilation checking. However, this is incorrect, as the interface file and bytecode objects could be in different states, e.g. the interface changes, but the bytecode library hasn't changed so we don't need to recompile and vice versa. By computing a `Fingerprint` for the `ModuleByteCode`, and recording it in the `LinkableUsage`, we know precisely whether the `ByteCode` object on disk is outdated. Thus, parts of this commit just makes sure that we efficiently compute a `Fingerprint` for `ModuleByteCode` and store it in the on-disk representation of `ModuleByteCode`. We change the `LoaderState` to retain `LinkableUsage`, which is smaller representation of a `Linkable`. This allows us to free the unneeded fields of `Linkable` after linking them. We declare the following memory invariants that this commit implements: * No `LinkablePart` should be retained from `LoaderState`. * `Linkable`s should be unloaded after they have been loaded. These invariants are unfortunately tricky to automatically uphold, so we are simply documenting our assumptions for now. We introduce the `linkable-space` test which makes sure that after loading, no `DotGBC` or `UnlinkedBCO` is retained. ------------------------- Metric Increase: MultiLayerModulesTH_OneShot ------------------------- We allocate a bit more, but the peak number of bytes doesn't change. While a bit unfortunate, accepting the metric increase. We add multiple new performance measurements where we were able to observe the desired memory invariants. Further, we add regression tests to validate that the recompilation checker behaves more correct than before. - - - - - 2d1c1997 by Simon Jakobi at 2026-03-31T04:41:46-04:00 Eliminate dictionary-passing in ListMap operations Mark the ListMap helpers 'INLINABLE' so importing modules can specialise the 'TrieMap (ListMap m)' methods and avoid recursive dictionary-passing.

Now we have * `GHC.Types.Var.FV`, which has a composable free-variable result type, very much in the spirit of the old `FV`, but much more robust. (It uses the "one shot trick".) * GHC.Core.TyCo.FVs now has just one technology for free variables. All this led to a lot of renaming. There are couple of error-message changes. The change in T18451 makes an already-poor error message even more mysterious. But it really needs a separate look. We also now traverse the AST in a different order leading to a different but still deterministic order for FVs and test output has been adjusted accordingly. - - - - - 4bf040c6 by sheaf at 2026-04-05T14:56:29-04:00 Add utility pprTrace_ function This function is useful for quick debugging, as it can be added to a where clause to pretty-print debugging information: fooBar x y | cond = body1 | otherwise = body2 where !_ = pprTrace_ "fooBar" $ vcat [ text "x:" <+> ppr x , text "y:" <+> ppr y , text "cond:" <+> ppr cond ] - - - - - 502e6ffe by Andrew Lelechenko at 2026-04-07T04:47:21-04:00 base: improve error message for Data.Char.chr As per https://github.com/haskell/core-libraries-committee/issues/384 - - - - - b21bd52e by Simon Peyton Jones at 2026-04-07T04:48:07-04:00 Refactor FunResCtxt a bit Fixes #27154 - - - - - 7fe84ea5 by Zubin Duggal at 2026-04-07T19:11:52+05:30 compiler: Warn when -finfo-table-map is used with -fllvm These are currently not supported together.

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.

Top-level StgRhsCon get lowered to ProtoStaticCons rather than to ProtoBCOs. A ProtoStaticCon gets allocated directly as a data con application on the heap (using the new primop newConApp#). Previously, we would allocate a ProtoBCO which, when evaluated, would PACK and return the constructor. A few more details are given in Note [Static constructors in Bytecode]. Secondly, this commit also fixes issue #25636 which was caused by linking *unlifted* constructors in BCO instructions as - (1) a thunk indexing the array of BCOs in a module - (2) which evaluated to a BCO which still had to be evaluated to return the unlifted constructor proper. The (2) issue has been resolved by allocating the static constructors directly. The (1) issue can be resolved by ensuring that we allocate all unlifted top-level constructors eagerly, and leave the knot-tying for the lifted BCOs and top-level constructors only. The top-level unlifted constructors are never mutually recursive, so we can allocate them all in one go as long as we do it in topological order. Lifted fields of unlifted constructors can still be filled by the knot-tied lifted variables since in those fields it is fine to keep those thunks. See Note [Tying the knot in createBCOs] for more details.

See `Note [Tying the knot in createBCOs]` for why tying the knot for the created BCOs is slightly difficult and why the topological sorting is necessary. This test fails when `let topoSortedObjs = topSortObjs objs` is substituted by `let topoSortedObjs = zip [0..] objs`, thus witnessing the toposort logic is correct and necessary. The test calls the ghci `createBCOs` directly because it is currently impossible to construct in Source Haskell a situation where a top-level static unlifted constructor depends on another (we don't have top-level unlifted constructors except for nullary constructors like `Leaf :: (UTree :: UnliftedType)`).

To do this, the "stop" actions of TcPlugin and DefaultingPlugin are split into two: one for the "post-typecheck" action, and one for the final shutdown action (after desugaring). This allows the plugins to be invoked by the pattern match checker (during desugaring) without having to be repeatedly re-initialised and stopped, fixing #26839. In the process, this commit modifies 'initTc' and 'initTcInteractive', adding an extra argument that describes whether to start/stop the 'TcM' plugins. See Note [Stop TcM plugins after desugaring] for an overview. - - - - - 42549222 by sheaf at 2026-04-27T09:33:50-04:00 Hadrian: add --keep-response-files This commit adds a Hadrian flag that allows response files to be retained.

Conceptually, we insert HPC ticks into the bytecode similar to how we insert breakpoints. HPC and breakpoints do not share the same tick array but we use a separate tick-array for hpc/breakpoint ticks during bytecode generation. We teach the bytecode interpreter to handle hpc ticks. The implementation is quite trivial, simply increment the counter in the global hpc_ticks array for the respective module. This hpc_ticks array is generated as part of the `CStub`, so we can rely on it existing. A tricky bit is "registering" a bytecode object for HPC instrumentation. In the compiled case, this is achieved via CStub and initializer/finalizers `.init` sections which are called when the executable is run. After the initializers have been invoked, which is before `hs_init_ghc`, we then call `startup_hpc` in `hs_init_ghc` iff any modules were "registered" for hpc instrumentation via `hs_hpc_module`. Since bytecode objects are loaded after starting up GHCi, this workflow doesn't work for supporting `hpc` and the `hpc` run-time is never started, even if a module is added for instrumentation. We fix this issue by employing the same technique as is for `SptEntry`s: * We introduce a new field to `CompiledByteCode`, called `ByteCodeHpcInfo` which contains enough information to call `hs_hpc_module`, allowing us to register the module for `hpc` instrumentation`. * After registering the module, we unconditionally call `startupHpc`, to make sure the .tix file is written. Calling `startupHpc` multiple times is safe. Calling `hs_hpc_module` multiple times for the same module is also safe. If we didn't register the hpc module in this way, evaluating a bytecode object instrumented with `-fhpc` without registering it in the `hpc` run-time will simply not generate any `.tix` files for this bytecode object. However, this shouldn't happen if everything is set up correctly.
