Cheng Shao pushed to branch wip/terrorjack/asan at Glasgow Haskell Compiler / GHC Commits: 9284a1f7 by Simon Hengel at 2026-06-23T05:55:33-04:00 Don't use global variables to address concurrency bugs! (fixes #27234) This was originally introduce with 88f38b03025386f0f1e8f5861eed67d80495168a to address #17922. In this specific case a better fix would have been to synchronize on stderr: withHandle_ "stderrSupportsAnsiColors" stderr $ \ _ -> do ... But apparently the dependency on `terminfo` was removed in 32ab07bf3d6ce45e8ea5b55e8095174a6b42a7f0, preventing #17922 in the first place. - - - - - 44309cd3 by Alan Zimmerman at 2026-06-23T05:56:20-04:00 EPA: remove LocatedL / SrcSpanAnnL and LocatedLI / SrcSpanAnnLI This is part of a refactor towards only having LocatedA / SrcSpanAnnA It removes the stated items, but has to add back one for BooleanFormula, LocatedBF / SrcSpanAnnBF This commit also use the HsConDetails RecCon extension point to capture the braces in a record constructor - - - - - 2f6a5534 by Simon Jakobi at 2026-06-23T15:46:20+02:00 Add -dstable-core-dump-order for stable Core dump ordering (#27296) The order of top-level bindings in Core dumps (-ddump-simpl etc.) is the compiler's Unique-sensitive internal processing order, so an unrelated upstream change can reorder them and defeat a textual diff of two dumps. This adds an opt-in flag -dstable-core-dump-order that reorders the top-level bindings of dumps routed through dumpPassResult into a stable, Unique-independent order, so two dumps line up across rebuilds. See Note [Stable Core dump order] in GHC.Core.Ppr for the sort key and its rationale. Adds tests T27296 (binders GHC emits in non-source order by default, asserted to come out stably ordered under the flag) and T27296b (an untidied -ddump-float-out dump pinning the ordering of the anonymous lvl floats by literal value).

Define them explicitly via the new integerSetBit[#], integerClearBit[#] and integerComplementBit[#], built on the BigNat# primitives, which avoid those allocations. Allocation is not eliminated entirely -- the negative (IN) cases would need in-place mutation, which is left as future work. The default methods constant-folded on literal arguments via the integerOr/integerAnd/integerXor rules, which fold literal Integers of any size. The explicit functions have no such rule, so they (their Word-argument wrappers, and the Bits Integer methods) are marked INLINE to expose the underlying primops to the simplifier; see Note [INLINE for constant folding of bit operations]. This restores folding only on the small-int (IS) path -- large literal Integers (IP/IN) are no longer constant-folded, a minor regression for that case. T8832 covers the IS-path folding. The new golden-output test T21176 checks all three operations against the default implementations across the sign/size boundaries, recording each result plus its integerCheck validity. The base and ghc-bignum interface- stability export goldens gain the new functions. The main changelog entry lives in changelog.d under a new ghc-internal section (renamed from ghc-prim).

It avoids repeated conversions while keeping the existing decoding behavior for invalid UTF-8 docstring chunks. The main changes are: * Render and carry docstrings as Text in Haddock-facing paths. * Use the Binary Text instance from GHC.Utils.Binary for Haddock interface files, and bump the Haddock binary interface version. * Add a FastString HTML instance so XHTML rendering avoids intermediate String allocation. * Keep HsDocStringChunk decoding lenient, matching the previous unpackHDSC behavior on invalid UTF-8 input. * Update the xhtml submodule to 3000.4.1.0, which contains the apostrophe escaping fix used by the Haddock test output.

Additionally, it is confusing that ZonkAny, while being a concrete type *represents* a meta variable, espeically in the compiler output. This patch changes the name of ZonkAny to UnusedType which is closer to its intended semantics and adds special pretty printing logic to display this type in the same fashion the compiler displays meta variables in other places, whenever they leak from the implementation to the user. It also exports the type from ghc-internal:GHC.Internal.Types in order to expose documentation.

This removes the now needless Platform argument from frAllocateReg, frGetFreeRegs and frReleaseReg. frInitFreeRegs keeps its Platform argument: the initial allocatable set is genuinely platform-dependent, see Note [Aarch64 Register x18 at Darwin and Windows].

The new structure looks like: <total name count> $modules.size for (mod, names) in $modules: $mod $names.size for table_ix, occ in $names $table_ix $occ i.e. we put the module just once, followed by all names in that module. When deserializing, we deserialize the module just once, and all the following `Name`s are constructed with a pointer to that same decoded `Module`. In `hoogle-test`, we must use `DNameEnv` rather than `Map Name`, otherwise the output fixities order was susceptible to changes in the uniques assigned to each Names, which is not stable.

Any code that creates `MCDiagnostic` directly, without going through `GHC.Driver.Errors.printMessage`, sidesteps `-fdiagnostics-as-json` (see e.g. !14616, !14475, !14492 !14548). To avoid this in the future, this change more narrowly controls who creates `MCDiagnostic` (see #24113). - - - - - 6f212121 by Facundo Domínguez at 2026-06-26T20:56:27-04:00 Encapsulate options of occurAnalysePgm in a record - - - - - adfbb179 by Facundo Domínguez at 2026-06-26T20:56:27-04:00 Allow to configure the occurrence analyser to retain some dead bindings This is needed by plugins that are the only consumers of a binding which is otherwise unused in the program.

Actually this eliminates the `(++)` entirely, as it seems to fuse with the `filter` expression. As a result there is a tiny speed-up when generating the .hi-files for modules with many imports. None of the changes affect compilation determinism as the module list is explicitly sorted to ensure a canonical order. - - - - - 2d0fd154 by Alan Zimmerman at 2026-06-29T11:44:00-04:00 EPA: Remove LocatedC / SrcSpanAnnC This is part of a cleanup of the zoo of SrcSpanAnnXXX types for exact print annotations. This one removes SrcSpanAnnC used for storing exact print annotations for contexts. It replaces it with an explicit `HsContext` data type that carries the annotations and the context. So, replace type HsContext pass = [LHsType pass] with type HsContext pass = HsContextDetails pass (LHsType pass) data HsContextDetails pass arg = HsContext { hsc_ext :: !(XHsContext pass) , hsc_ctxt :: [arg] } | XHsContextDetails !(XXHsContextDetails pass) We need the parameterised HsContextDetails because it is used both for HsQual carrying 'LHsExpr p' and "normal" contexts carrying 'LHsType p'. - - - - - cca0d589 by Luite Stegeman at 2026-06-30T13:33:40-04:00 rts: handle large AP closures in compacting GC The function update_fwd_large in the compacting GC could run into an unexpected object with the following error: internal error: update_fwd_large: unknown/strange object 24 Closure type 24 is the AP closure, which was not handled in upd_fwd_large.

In the past the `Quasi` typeclass was both part of the external, public-facing interface, and was used to give the implementation of `Q`. Now we separate out these two distinct roles. `Quasi` continues to exist in the public interface, but we introduce a new `MetaHandlers` type, which is equivalent to `Dict Quasi`. `Q a` is now defined to be `MetaHandlers -> IO a`, and, crucially, the constructor and the new `MetaHandlers` type are not exposed from the public interface. This gives us the ability to vary the interface on the GHC side without forcing a breaking change on the `template-haskell` side. Similarly `template-haskell` has more freedom to change the `Quasi` typeclass without needing any changes in `lib:ghc`.

Before proc-points splitting, this pass computes liveliness of local registers, and spills those alive across a Cmm native call onto the stack. It need to traverse all middle nodes in each block and check whether a local register is an assignee, if so then the previous mapping in `sm_regs` is invalidated and needs to be dropped. However, it didn't handle `CmmUnsafeForeignCall` node which may also assign to a local register. When proc-points splitting is enabled, this can produce an invalid basic block that doesn't properly backup the updated local register to the stack before doing a Cmm call, resulting in completely invalid runtime behavior. The patch also adds a `T27447` regression test. With no-TNTC or with LLVM backend, without the fix the test case would output a stale 0x1111111111111111 value, instead of the expected 0x2222222222222222 output. Fixes #27447.
