Instead of keeping the constructor but deprecating it, this commit makes it into a bundled pattern synonym of the Pragma datatype. We no longer deprecate it; it's useful for handling old-form specialise pragmas. - - - - - 26dbcf61 by fendor at 2025-08-30T05:10:08-04:00 Move stack decoding logic from ghc-heap to ghc-internal The stack decoding logic in `ghc-heap` is more sophisticated than the one currently employed in `CloneStack`. We want to use the stack decoding implementation from `ghc-heap` in `base`. We cannot simply depend on `ghc-heap` in `base` due do bootstrapping issues. Thus, we move the code that is necessary to implement stack decoding to `ghc-internal`. This is the right location, as we don't want to add a new API to `base`. Moving the stack decoding logic and re-exposing it in ghc-heap is insufficient, though, as we have a dependency cycle between. * ghc-heap depends on stage1:ghc-internal * stage0:ghc depends on stage0:ghc-heap To fix this, we remove ghc-heap from the set of `stage0` dependencies. This is not entirely straight-forward, as a couple of boot dependencies, such as `ghci` depend on `ghc-heap`. Luckily, the boot compiler of GHC is now >=9.10, so we can migrate `ghci` to use `ghc-internal` instead of `ghc-heap`, which already exports the relevant modules. However, we cannot 100% remove ghc's dependency on `ghc-heap`, since when we compile `stage0:ghc`, `stage1:ghc-internal` is not yet available. Thus, when we compile with the boot-compiler, we still depend on an older version of `ghc-heap`, and only use the modules from `ghc-internal`, if the `ghc-internal` version is recent enough. ------------------------- Metric Increase: T24602_perf_size T25046_perf_size_gzip T25046_perf_size_unicode T25046_perf_size_unicode_gzip size_hello_artifact size_hello_artifact_gzip size_hello_unicode size_hello_unicode_gzip ------------------------- These metric increases are unfortunate, they are most likely caused by the larger (literally in terms of lines of code) stack decoder implementation that are now linked into hello-word binaries.

So tricky was it that it did so wrong. In this MR I locate all the fancy footwork for coercion optimisation in GHC.Core.Coercion.Opt, where it belongs.

For example, if a rule is always active, we only fire rules that are themselves always active when simplifying the RHS. Ditto for inline activations. This is achieved by setting the simplifier phase to a range of phases, using the new SimplPhaseRange constructor. Then: 1. When simplifying the RHS of a rule, or of a stable unfolding, we set the simplifier phase to a range of phases, computed from the activation of the RULE/unfolding activation, using the function 'phaseFromActivation'. The details are explained in Note [What is active in the RHS of a RULE?] in GHC.Core.Opt.Simplify.Utils. 2. The activation check for other rules and inlinings is then: does the activation of the other rule/inlining cover the whole phase range set in sm_phase? This continues to use the 'isActive' function, which now accounts for phase ranges. On the way, this commit also moves the exact-print SourceText annotation from the Activation datatype to the ActivationAnn type. This keeps the main Activation datatype free of any extra cruft.

To yield, we need to put the stack in a state such that when execution is resumed we are back to where we yielded from. Previously, a BKR_FUN could only head a function BCO because we only knew how to construct a valid stack for yielding from one -- simply add `apply_interp_info` + the BCO to resume executing. This is valid because the stack at the start of run_BCO is headed by that BCO's arguments. However, in case continuation BCOs (as per Note [Case continuation BCOs]), we couldn't easily reconstruct a valid stack that could be resumed because we dropped too soon the stack frames regarding the value returned (stg_ret) and received (stg_ctoi) by that continuation. This is especially tricky because of the variable type and size return frames (e.g. pointer ret_p/ctoi_R1p vs a tuple ret_t/ctoi_t2). The trick to being able to yield from a BRK_FUN at the start of a case cont BCO is to stop removing the ret frame headers eagerly and instead keep them until the BCO starts executing. The new layout at the start of a case cont. BCO is described by the new Note [Stack layout when entering run_BCO]. Now, we keep the ret_* and ctoi_* frames when entering run_BCO. A BRK_FUN is then executed if found, and the stack is yielded as-is with the preserved ret and ctoi frames. Then, a case cont BCO's instructions always SLIDE off the headers of the ret and ctoi frames, in StgToByteCode.doCase, turning a stack like | .... | +---------------+ | fv2 | +---------------+ | fv1 | +---------------+ | BCO | +---------------+ | stg_ctoi_ret_ | +---------------+ | retval | +---------------+ | stg_ret_..... | +---------------+ into | .... | +---------------+ | fv2 | +---------------+ | fv1 | +---------------+ | retval | +---------------+ for the remainder of the BCO. Moreover, this more uniform approach of keeping the ret and ctoi frames means we need less ad-hoc logic concerning the variable size of ret_tuple vs ret_p/np frames in the code generator and interpreter: Always keep the return to cont. stack intact at the start of run_BCO, and the statically generated instructions will take care of adjusting it. Unlocks BRK_FUNs at the start of case cont. BCOs which will enable a better user-facing step-out (#26042) which is free of the bugs the current BRK_ALTS implementation suffers from (namely, using BRK_FUN rather than BRK_ALTS in a case cont. means we'll never accidentally end up in a breakpoint "deeper" than the continuation, because we stop at the case cont itself rather than on the first breakpoint we evaluate after it). - - - - - ade3c1e6 by Rodrigo Mesquita at 2025-09-02T12:19:59-04:00 BRK_FUN with InternalBreakLocs for code-generation time breakpoints At the start of a case continuation BCO, place a BRK_FUN. This BRK_FUN uses the new "internal breakpoint location" -- allowing us to come up with a valid source location for this breakpoint that is not associated with a source-level tick. For case continuation BCOs, we use the last tick seen before it as the source location. The reasoning is described in Note [Debugger: Stepout internal break locs]. Note how T26042c, which was broken because it displayed the incorrect behavior of the previous step out when we'd end up at a deeper level than the one from which we initiated step-out, is now fixed. As of this commit, BRK_ALTS is now dead code and is thus dropped. Note [Debugger: Stepout internal break locs] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Step-out tells the interpreter to run until the current function returns to where it was called from, and stop there. This is achieved by enabling the BRK_FUN found on the first RET_BCO frame on the stack (See [Note Debugger: Step-out]). Case continuation BCOs (which select an alternative branch) must therefore be headed by a BRK_FUN. An example: f x = case g x of <--- end up here 1 -> ... 2 -> ... g y = ... <--- step out from here - `g` will return a value to the case continuation BCO in `f` - The case continuation BCO will receive the value returned from g - Match on it and push the alternative continuation for that branch - And then enter that alternative. If we step-out of `g`, the first RET_BCO on the stack is the case continuation of `f` -- execution should stop at its start, before selecting an alternative. (One might ask, "why not enable the breakpoint in the alternative instead?", because the alternative continuation is only pushed to the stack *after* it is selected by the case cont. BCO) However, the case cont. BCO is not associated with any source-level tick, it is merely the glue code which selects alternatives which do have source level ticks. Therefore, we have to come up at code generation time with a breakpoint location ('InternalBreakLoc') to display to the user when it is stopped there. Our solution is to use the last tick seen just before reaching the case continuation. This is robust because a case continuation will thus always have a relevant breakpoint location: - The source location will be the last source-relevant expression executed before the continuation is pushed - So the source location will point to the thing you've just stepped out of - Doing :step-local from there will put you on the selected alternative (which at the source level may also be the e.g. next line in a do-block) Examples, using angle brackets (<<...>>) to denote the breakpoint span: f x = case <<g x>> {- step in here -} of 1 -> ... 2 -> ...> g y = <<...>> <--- step out from here ... f x = <<case g x of <--- end up here, whole case highlighted 1 -> ... 2 -> ...>> doing :step-local ... f x = case g x of 1 -> <<...>> <--- stop in the alternative 2 -> ... A second example based on T26042d2, where the source is a do-block IO action, optimised to a chain of `case expressions`. main = do putStrLn "hello1" <<f>> <--- step-in here putStrLn "hello3" putStrLn "hello4" f = do <<putStrLn "hello2.1">> <--- step-out from here putStrLn "hello2.2" ... main = do putStrLn "hello1" <<f>> <--- end up here again, the previously executed expression putStrLn "hello3" putStrLn "hello4" doing step/step-local ... main = do putStrLn "hello1" f <<putStrLn "hello3">> <--- straight to the next line putStrLn "hello4" Finishes #26042 - - - - - c66910c0 by Rodrigo Mesquita at 2025-09-02T12:19:59-04:00 debugger: Re-use the last BreakpointId whole in step-out Previously, to come up with a location to stop at for `:stepout`, we would store the location of the last BreakpointId surrounding the continuation, as described by Note [Debugger: Stepout internal break locs]. However, re-using just the location from the last source breakpoint isn't sufficient to provide the necessary information in the break location. Specifically, it wouldn't bind any variables at that location. Really, there is no reason not to re-use the last breakpoint wholesale, and re-use all the information we had there. Step-out should behave just as if we had stopped at the call, but s.t. continuing will not re-execute the call. This commit updates the CgBreakInfo to always store a BreakpointId, be it the original one or the one we're emulating (for step-out). It makes variable bindings on :stepout work - - - - - e4abed7b by sheaf at 2025-09-02T12:20:40-04:00 Revert accidental changes to hie.yaml - - - - - 003b715b by meooow25 at 2025-09-02T23:48:51+02:00 Adjust the strictness of Data.List.iterate' * Don't force the next element in advance when generating a (:). * Force the first element to WHNF like every other element.

PUSH_L 0 SLIDE 1 1 We do this often by generically constructing a tail call from a function atom that may be somewhere arbitrary on the stack. However, for the special case that the function can be found directly on top of the stack, as part of the arguments, it's plain redundant to push then slide it. In this commit we add a small optimisation to the generation of tailcalls in bytecode. Simply: lookahead for the function in the stack. If it is the first thing on the stack and it is part of the arguments which would be dropped as we entered the tail call, then don't push then slide it. In a simple example (T26042b), this already produced a drastic improvement in generated code (left is old, right is with this patch): ```diff 3c3 < 2025-07-29 10:14:02.081277 UTC --- > 2025-07-29 10:50:36.560949 UTC 160,161c160 < PUSH_L 0 < SLIDE 1 2 --- > SLIDE 1 1 164,165d162 < PUSH_L 0 < SLIDE 1 1 175,176c172 < PUSH_L 0 < SLIDE 1 2 --- > SLIDE 1 1 179,180d174 < PUSH_L 0 < SLIDE 1 1 206,207d199 < PUSH_L 0 < SLIDE 1 1 210,211d201 < PUSH_L 0 < SLIDE 1 1 214,215d203 < PUSH_L 0 < SLIDE 1 1 218,219d205 < PUSH_L 0 < SLIDE 1 1 222,223d207 < PUSH_L 0 < SLIDE 1 1 ... 600,601c566 < PUSH_L 0 < SLIDE 1 2 --- > SLIDE 1 1 604,605d568 < PUSH_L 0 < SLIDE 1 1 632,633d594 < PUSH_L 0 < SLIDE 1 1 636,637d596 < PUSH_L 0 < SLIDE 1 1 640,641d598 < PUSH_L 0 < SLIDE 1 1 644,645d600 < PUSH_L 0 < SLIDE 1 1 648,649d602 < PUSH_L 0 < SLIDE 1 1 652,653d604 < PUSH_L 0 < SLIDE 1 1 656,657d606 < PUSH_L 0 < SLIDE 1 1 660,661d608 < PUSH_L 0 < SLIDE 1 1 664,665d610 < PUSH_L 0 < SLIDE 1 1 ``` I also compiled lib:Cabal to bytecode and counted the number of bytecode lines with `find dist-newstyle -name "*.dump-BCOs" -exec wc {} +`: with unoptimized core: 1190689 lines (before) - 1172891 lines (now) = 17798 less redundant instructions (-1.5% lines) with optimized core: 1924818 lines (before) - 1864836 lines (now) = 59982 less redundant instructions (-3.1% lines) - - - - - 8b2c72c0 by L0neGamer at 2025-09-04T06:32:03-04:00 Add Control.Monad.thenM and Control.Applicative.thenA - - - - - 39e1b7cb by Teo Camarasu at 2025-09-04T06:32:46-04:00 ghc-internal: invert dependency of GHC.Internal.TH.Syntax on Data.Data This means that Data.Data no longer blocks building TH.Syntax, which allows greater parallelism in our builds. We move the Data.Data.Data instances to Data.Data. Quasi depends on Data.Data for one of its methods, so, we split the Quasi/Q, etc definition out of GHC.Internal.TH.Syntax into its own module. This has the added benefit of splitting up this quite large module. Previously TH.Syntax was a bottleneck when compiling ghc-internal. Now it is less of a bottle-neck and is also slightly quicker to compile (since it no longer contains these instances) at the cost of making Data.Data slightly more expensive to compile. TH.Lift which depends on TH.Syntax can also compile quicker and no longer blocks ghc-internal finishing to compile.

We know the result is always Type-like, so we don't need scaledFunTys to try to rediscover that from the kind.

[Git][ghc/ghc][wip/spj-apporv-Oct24] 23 commits: Refactor ForAllCo
by Apoorv Ingle (＠ani) 11 Sep '25

11 Sep '25

Apoorv Ingle pushed to branch wip/spj-apporv-Oct24 at Glasgow Haskell Compiler / GHC Commits: 94b62aa7 by Simon Peyton Jones at 2025-09-08T03:37:14-04:00 Refactor ForAllCo This is a pure refactor, addressing #26389. It arranges that the kind coercion in a ForAllCo is a MCoercion, rather than a plain Coercion, thus removing redundancy in the common case. See (FC8) in Note [ForAllCo] It's a nice cleanup. - - - - - 624afa4a by sheaf at 2025-09-08T03:38:05-04:00 Use tcMkScaledFunTys in matchExpectedFunTys We should use tcMkScaledFunTys rather than mkScaledFunTys in GHC.Tc.Utils.Unify.matchExpectedFunTys, as the latter crashes when the kind of the result type is a bare metavariable. We know the result is always Type-like, so we don't need scaledFunTys to try to rediscover that from the kind. Fixes #26277 - - - - - 0975d2b6 by sheaf at 2025-09-08T03:38:54-04:00 Revert "Remove hptAllFamInstances usage during upsweep" This reverts commit 3bf6720eff5e86e673568e756161e6d6150eb440. - - - - - 0cf34176 by soulomoon at 2025-09-08T03:38:54-04:00 Family consistency checks: add test for #26154 This commit adds the test T26154, to make sure that GHC doesn't crash when performing type family consistency checks. This test case was extracted from Agda. Fixes #26154 - - - - - ba210d98 by Simon Peyton Jones at 2025-09-08T16:26:36+01:00 Report solid equality errors before custom errors This MR fixes #26255 by * Reporting solid equality errors like Int ~ Bool before "custom type errors". See comments in `report1` in `reportWanteds` * Suppressing errors that arise from superclasses of Wanteds. See (SCE1) in Note [Suppressing confusing errors] More details in #26255. - - - - - b6249140 by Simon Peyton Jones at 2025-09-10T10:42:38-04:00 Fix a scoping error in Specialise This small patch fixes #26329, which triggered a scoping error. Test is in T21391, with -fpolymorphic-specialisation enabled - - - - - 45305ab8 by sheaf at 2025-09-10T10:43:29-04:00 Make rationalTo{Float,Double} inline in phase 0 We hold off on inlining these until phase 0 to allow constant-folding rules to fire. However, once we get to phase 0, we should inline them, e.g. to expose unboxing opportunities. See CLC proposal #356. - - - - - 0959d4bc by Andreas Klebinger at 2025-09-10T10:44:12-04:00 Add regression test for #26056 - - - - - dc79593d by sheaf at 2025-09-10T10:45:01-04:00 Deep subsumption: unify mults without tcEqMult As seen in #26332, we may well end up with a non-reflexive multiplicity coercion when doing deep subsumption. We should do the same thing that we do without deep subsumption: unify the multiplicities normally, without requiring that the coercion is reflexive (which is what 'tcEqMult' was doing). Fixes #26332 - - - - - 4bfe2269 by sheaf at 2025-09-10T10:45:50-04:00 lint-codes: fixup MSYS drive letter on Windows This change ensures that System.Directory.listDirectory doesn't trip up on an MSYS-style path like '/c/Foo' when trying to list all testsuite stdout/stderr files as required for testing coverage of GHC diagnostic codes in the testsuite. Fixes #25178 - - - - - 56540775 by Ben Gamari at 2025-09-10T10:46:32-04:00 gitlab-ci: Disable split sections on FreeBSD Due to #26303. - - - - - 1537784b by Moritz Angermann at 2025-09-10T10:47:13-04:00 Improve mach-o relocation information This change adds more information about the symbol and addresses we try to relocate in the linker. This significantly helps when deubbging relocation issues reported by users. - - - - - 4e67855b by Moritz Angermann at 2025-09-10T10:47:54-04:00 test.mk expect GhcLeadingUnderscore, not LeadingUnderscore (in line with the other Ghc prefixed variables. - - - - - c1cdd265 by Moritz Angermann at 2025-09-10T10:48:35-04:00 testsuite: Fix broken exec_signals_child.c There is no signal 0.

As a consequence, the latter must be explicitly flushed because GHC won't flush it before exiting. - - - - - 80a07571 by Sylvain Henry at 2025-09-11T11:28:18-04:00 Testsuite: fix debug_rts detection Running the testsuite without Hadrian should set config.debug_rts correctly too. - - - - - 6b2c022b by Apoorv Ingle at 2025-09-11T14:58:03-05:00 This commit: - Streamlines implementations of `tcExpr` and `tcXExpr` to work on `XExpr` Calls `setInGeneratedCode` everytime the typechecker goes over an `XExpr` - Kills `VACtxt` (and its associated VAExpansion and VACall) datatype, it is subsumed by simply a SrcSpan. - Kills the function `addHeadCtxt` as it is now mearly setting a location - The function `tcValArgs` does its own argument number management - Makes `splitHsApps` not look through `XExpr` - `tcExprSigma` is called if the head of the expression after calling `splitHsApps` turns out to be an `XExpr` - Removes location information from `OrigPat` payload - Removes special case of tcBody from `tcLambdaMatches` - Removes special case of `dsExpr` for `ExpandedThingTc` - Moves `setQLInstLevel` inside `tcInstFun` - Rename `HsThingRn` to `SrcCodeCtxt` - Kills `tcl_in_gen_code` and `tcl_err_ctxt`.

[Git][ghc/ghc][wip/marge_bot_batch_merge_job] 15 commits: T16180: indicate that the stack isn't executable
by Marge Bot (＠marge-bot) 11 Sep '25

11 Sep '25

Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: db3276bb by Sylvain Henry at 2025-09-11T11:27:28-04:00 T16180: indicate that the stack isn't executable - - - - - 11eeeba7 by Sylvain Henry at 2025-09-11T11:27:28-04:00 Fix some tests (statically linked GHC vs libc) When GHC is linked statically, the stdout C global variable that GHC uses isn't shared with the stdout C global variable used by loaded code. As a consequence, the latter must be explicitly flushed because GHC won't flush it before exiting. - - - - - 80a07571 by Sylvain Henry at 2025-09-11T11:28:18-04:00 Testsuite: fix debug_rts detection Running the testsuite without Hadrian should set config.debug_rts correctly too. - - - - - 536643b4 by Duncan Coutts at 2025-09-11T14:04:27-04:00 Handle heap allocation failure in I/O primops The current I/O managers do not use allocateMightFail, but future ones will. To support this properly we need to be able to return to the primop with a failure. We simply use a bool return value. Currently however, we will just throw an exception rather than calling the GC because that's what all the other primops do too. For the general issue of primops invoking GC and retrying, see https://gitlab.haskell.org/ghc/ghc/-/issues/24105 - - - - - e48ccb87 by Duncan Coutts at 2025-09-11T14:04:27-04:00 Move (and rename) scheduleStartSignalHandlers into RtsSignals.h Previously it was a local helper (static) function in Schedule.c. Rename it to startPendingSignalHandlers and deifine it as an inline header function in RtsSignals.h. So it should still be fast. Each (new style) I/O manager is going to need to do the same, so eliminating the duplication now makes sense. - - - - - 3864ca04 by Duncan Coutts at 2025-09-11T14:04:27-04:00 Reduce detail in printThreadBlockage I/O blocking cases The printThreadBlockage is used in debug tracing output. For the cases BlockedOn{Read,Write,Delay} the output previously included the fd that was being waited on, and the delay target wake time. Superficially this sounds useful, but it's clearly not that useful because it was already wrong for the Win32 non-threaded I/O manager. In that situation it will print garbage (the async_result pointer, cast to a fd or a time). So given that it apparently never mattered that the information was accurate, then it's hardly a big jump to say it doesn't matter if it is present at all. A good reason to remove it is that otherwise we have to make a new API and a per-I/O manager implementation to fetch the information. And for some I/O manager implementations, this information is not available. It is not available in the win32 non-threaded I/O manager. And for some future Linux ones, there is no need for the fd to be stored, so storing it would be just extra space used for very little gain. So the simplest thing is to just remove the detail. - - - - - 49190f7c by Duncan Coutts at 2025-09-11T14:04:27-04:00 Add TimeoutQueue.{c,h} and corresponding tests A data structure used to efficiently manage a collection of timeouts. It is a priority queue based on absolute expiry time. It uses 64bit high-precision Time for the keys. The values are normal closures which allows for example using MVars for unblocking. It is common in many applications for timeouts to be created and then deleted or altered before they expire. Thus the choice of data structure for timeouts should support this efficiently. The implementation choice here is a leftist heap with the extra feature that it supports deleting arbitrary elements, provided the caller retain a pointer to the element. While the deleteMin operation takes O(log n) time, as in all heap structures, the delete operation for arbitrary elements /typically/ takes O(1), and only O(log n) in the worst case. In practice, when managing thousands of timeouts it can be a factor of 10 faster to delete a random timeout queue element than to remove the minimum element. This supports the common use case. The plan is to use it in some of the RTS-side I/O managers to support their timer functionality. In this use case the heap value will be an MVar used for each timeout to unblock waiting threads. - - - - - b193f5e6 by Duncan Coutts at 2025-09-11T14:04:27-04:00 Add ClosureTable.{c,h} and corresponding tests A table of pointers to closures on the GC heap with stable indexes. It provides O(1) alloc, free and lookup. The table can be expanded using a simple doubling strategy: in which case allocation is typically O(1) and occasionally O(n) for overall amortised O(1). No shrinking is used. The table itself is heap allocated, and points to other heap objects. As such it's necessary to use markClosureTable to ensure the table is used as a GC root to keep the table entries alive, and maintain proper pointers to them as the GC moves heap objects about. It is designed to be allocated and accesses exclusively from a single capability, enabling it to work without any locking. It is thus similar to the StablePtr table, but per-capability which removes the need for locking. It _should_ also provide lower GC pause times with the non-moving GC by spending only O(1) time in markClosureTable, vs O(n) for markStablePtrTable. The plan is to use it in some of the I/O managers to keep track of in-flight I/O operations (but not timers). This allows the tracking info to be kept on the (unpinned) GC heap, and shared with Haskell code, and by putting a pointer to the tracking information in a table, the index remains stable and can be passed via foreign code (like the kernel). - - - - - b49114dc by Duncan Coutts at 2025-09-11T14:04:27-04:00 Add the StgAsyncIOOp closure type This is intended to be used by multiple I/O managers to help with tracking in-flight I/O operations. It is called asynchronous because from the point of view of the RTS we have many such operations in progress at once. From the point of view of a Haskell thread of course it can look synchronous. - - - - - be5e4002 by Duncan Coutts at 2025-09-11T14:04:27-04:00 Add StgAsyncIOOp and StgTimeoutQueue to tso->block_info These will be used by new I/O managers, for threads blocked on I/O or timeouts. - - - - - 3aadd06a by Duncan Coutts at 2025-09-11T14:04:27-04:00 Add a new I/O manager based on poll() This is a proof of concept I/O manager, to show how to add new ones neatly, using the ClosureTable and TimeoutQueue infrastructure. It uses the old unix poll() API, so it is of course limited in performance by that, but it should have the benefit of wide compatibility. Also we neatly avoid a name clash with the existing select() I/O manager. Compared to the select() I/O manager: 1. beause it uses poll() it is not limited to 1024 file descriptors (but it's still O(n) so don't expect great performance); 2. it should have much faster threadDelay (when using it in lots of threads at once) because it's based on the new TimeoutQueue which is O(log n) rather than O(n). Some of the code related to timers/timouts is put into a shared module rts/posix/Timeout.{h,c} since it is intended to be shared with other similar I/O managers. - - - - - a4cc36ef by Duncan Coutts at 2025-09-11T14:04:28-04:00 Document the I/O managers in the user guide and note the new poll I/O manager in the release notes. - - - - - f7278537 by Duncan Coutts at 2025-09-11T14:04:28-04:00 Use the poll() I/O manager by default That is, for the non-threaded RTS, prefer the poll I/O manager over the legacy select() one, if both can be enabled. This patch is primarily for CI testing, so we should probably remove this patch before merging. We can change defaults later after wider testing and feedback. - - - - - aed63b81 by Simon Peyton Jones at 2025-09-11T14:04:32-04:00 Solve forall-constraints via an implication, again In this earlier commit: commit 953fd8f1dc080f1c56e3a60b4b7157456949be29 Author: Simon Peyton Jones <simon.peytonjones(a)gmail.com> Date: Mon Jul 21 10:06:43 2025 +0100 Solve forall-constraints immediately, or not at all I used a all-or-nothing strategy for quantified constraints (aka forall-constraints). But alas that fell foul of #26315, and #26376. So this MR goes back to solving a quantified constraint by turning it into an implication; UNLESS we are simplifying constraints from a SPECIALISE pragma, in which case the all-or-nothing strategy is great. See: Note [Solving a Wanted forall-constraint] Other stuff in this MR: * TcSMode becomes a record of flags, rather than an enumeration type; much nicer. * Some fancy footwork to avoid error messages worsening again (The above MR made them better; we want to retain that.)

Cheng Shao pushed to branch wip/romes/26227 at Glasgow Haskell Compiler / GHC Commits: 246b7853 by Matthew Pickering at 2025-08-07T06:58:30-04:00 level imports: Check the level of exported identifiers The level imports specification states that exported identifiers have to be at level 0. This patch adds the requird level checks that all explicitly mentioned identifiers occur at level 0. For implicit export specifications (T(..) and module B), only level 0 identifiers are selected for re-export. ghc-proposal: https://github.com/ghc-proposals/ghc-proposals/pull/705 Fixes #26090 - - - - - 358bc4fc by fendor at 2025-08-07T06:59:12-04:00 Bump GHC on darwin CI to 9.10.1 - - - - - 1903ae35 by Matthew Pickering at 2025-08-07T12:21:10+01:00 ipe: Place strings and metadata into specific .ipe section By placing the .ipe metadata into a specific section it can be stripped from the final binary if desired. ``` objcopy --remove-section .ipe <binary> upx <binary> ``` Towards #21766 - - - - - c80dd91c by Matthew Pickering at 2025-08-07T12:22:42+01:00 ipe: Place magic word at the start of entries in the .ipe section The magic word "IPE\nIPE\n" is placed at the start of .ipe sections, then if the section is stripped, we can check whether the section starts with the magic word or not to determine whether there is metadata present or not. Towards #21766 - - - - - cab42666 by Matthew Pickering at 2025-08-07T12:22:42+01:00 ipe: Use stable IDs for IPE entries IPEs have historically been indexed and reported by their address. This makes it impossible to compare profiles between runs, since the addresses may change (due to ASLR) and also makes it tricky to separate out the IPE map from the binary. This small patch adds a stable identifier for each IPE entry. The stable identifier is a single 64 bit word. The high-bits are a per-module identifier and the low bits identify which entry in each module. 1. When a node is added into the IPE buffer it is assigned a unique identifier from an incrementing global counter. 2. Each entry already has an index by it's position in the `IpeBufferListNode`. The two are combined together by the `IPE_ENTRY_KEY` macro. Info table profiling uses the stable identifier rather than the address of the info table. The benefits of this change are: * Profiles from different runs can be easily compared * The metadata can be extracted from the binary (via the eventlog for example) and then stripped from the executable.

This behavior is undesireable in some cases and there is not really a good way to work around it. Especially for downstream packagers, modifying this via UserSettings is not really feasible since such a source file has to be kept in sync with Settings/Default.hs manually since it can't import Settings.Default or any predefined Flavour definitions. To avoid having to add a new setting to cfg/system.config and/or a new configure flag (though I'm happy to implement both if required), I've chosen to take --with-curses-* being set explicitly as an indication that the user wants to have terminfo enabled. This would work for Nixpkgs which sets these flags [1] as well as haskell.nix [2] (which goes to some extreme measures [3] [4] to force terminfo in all scenarios). In general, I'm an advocate for making the GHC build be the same for native and cross insofar it is possible since it makes packaging GHC and Haskell related things while still supporting cross much less compilicated. A more minimal GHC with reduced dependencies should probably be a specific flavor, not the default. Partially addresses #26288 by forcing terminfo to be built if the user explicitly passes configure flags related to it. However, it isn't built by default when cross-compiling yet nor is there an explicit way to control the package being built.

For example, we now are properly able to prove the subtyping relationship ((∀ a. a->a) -> Int) -> Bool <= β[tau] Bool for an unfilled metavariable β. In this case (with an AppTy on the right), we used to fall back to unification. No longer: now, given that the LHS is a FunTy and that the RHS is a deep rho type (does not need any instantiation), we try to make the RHS into a FunTy, viz. β := (->) γ We can then continue using covariance & contravariance of the function arrow, which allows us to prove the subtyping relationship, instead of trying to unify which would cause us to error out with: Couldn't match expected type ‘β’ with actual type ‘(->) ((∀ a. a -> a) -> Int) See Note [FunTy vs non-FunTy case in tc_sub_type_deep] in GHC.Tc.Utils.Unify. The other main improvement in this patch concerns type inference. The main subsumption logic happens (before & after this patch) in GHC.Tc.Gen.App.checkResultTy. However, before this patch, all of the DeepSubsumption logic only kicked in in 'check' mode, not in 'infer' mode. This patch adds deep instantiation in the 'infer' mode of checkResultTy when we are doing deep subsumption, which allows us to accept programs such as: f :: Int -> (forall a. a->a) g :: Int -> Bool -> Bool test1 b = case b of True -> f False -> g test2 b = case b of True -> g False -> f See Note [Deeply instantiate in checkResultTy when inferring]. Finally, we add representation-polymorphism checks to ensure that the lambda abstractions we introduce when doing subsumption obey the representation polymorphism invariants of Note [Representation polymorphism invariants] in GHC.Core. See Note [FunTy vs FunTy case in tc_sub_type_deep]. This is accompanied by a courtesy change to `(<.>) :: HsWrapper -> HsWrapper -> HsWrapper`, adding the equation: WpCast c1 <.> WpCast c2 = WpCast (c1 `mkTransCo` c2) This is useful because mkWpFun does not introduce an eta-expansion when both of the argument & result wrappers are casts; so this change allows us to avoid introducing lambda abstractions when casts suffice.

This API is exposed via `ghc-experimental`. By overriding how we collect `Backtraces`, we can control how the `Backtraces` are displayed to the user by newtyping `Backtraces` and giving a different instance for `ExceptionAnnotation`. A concrete use-case for this feature is allowing us to experiment with alternative stack decoders, without having to modify `base`, which take additional information from the stack frames. This commit does not modify how `Backtraces` are currently collected or displayed. - - - - - 66024722 by fendor at 2025-08-13T21:03:43-04:00 Expose Backtraces internals from ghc-experimental Additionally, expose the same API `base:Control.Exception.Backtrace` to make it easier to use as a drop-in replacement. - - - - - a766286f by Reed Mullanix at 2025-08-13T21:04:36-04:00 ghc-internal: Fix naturalAndNot for NB/NS case When the first argument to `naturalAndNot` is larger than a `Word` and the second is `Word`-sized, `naturalAndNot` will truncate the result: ``` >>> naturalAndNot ((2 ^ 65) .|.

Any code that creates `MCDiagnostic` directly, without going through `GHC.Driver.Errors.printMessage`, side steps `-fdiagnostics-as-json` (see e.g. !14475, !14492 !14548). To avoid this in the future I want to control more narrowly who creates `MCDiagnostic` (see #24113). Some parts of the compiler use `MCDiagnostic` purely for formatting purposes, without creating any real compiler diagnostics. This change introduces a helper function, `formatDiagnostic`, that can be used in such cases instead of constructing `MCDiagnostic`. - - - - - a8b2fbae by Teo Camarasu at 2025-08-13T21:07:24-04:00 rts: ensure MessageBlackHole.link is always a valid closure We turn a MessageBlackHole into an StgInd in wakeBlockingQueue().

This allows us to extract the data later when decoding the stack, for example when an exception is thrown, showing more information to the user without having to annotate the full call-stack with `HasCallStack` constraints. A new stack frame value is introduced `AnnFrame`, which consists of nothing but a generic payload. The primop has a small wrapper API that allows users to annotate their call-stack in programs. There is a pure API and an IO-based one. The former is a little bit dubious, as it affects the evaluation of a program, so use with care. The latter is "safe", as it doesn't change the evaluation of the program. The stack annotation mechanism is similarly implemented to the `ExceptionAnnotation` and `Exception`, there is a typeclass to indicate something can be pushed onto the call-stack and all values are wrapped in the existential `SomeStackAnnotation`, which recover the type of the annotation payload. There is currently no builtin way to show the stack annotations when `Backtraces` are displayed (i.e., when showing stack traces to the user), which we will address in a follow-up MR. ------------------------- Metric Increase: ghc_experimental_so ------------------------- We increase the size of the package, so this is not unreasonable.

We want to use the stack decoding implementation from `ghc-heap` in `base`. We cannot simply depend on `ghc-heap` in `base` due do bootstrapping issues. Thus, we move the code that is necessary to implement stack decoding to `ghc-internal`. This is the right location, as we don't want to add a new API to `base`. Moving the stack decoding logic and re-exposing it in ghc-heap is insufficient, though, as we have a dependency cycle between. * ghc-heap depends on stage1:ghc-internal * stage0:ghc depends on stage0:ghc-heap To fix this, we remove ghc-heap from the set of `stage0` dependencies. This is not entirely straight-forward, as a couple of boot dependencies, such as `ghci` depend on `ghc-heap`. Luckily, the boot compiler of GHC is now >=9.10, so we can migrate `ghci` to use `ghc-internal` instead of `ghc-heap`, which already exports the relevant modules. However, we cannot 100% remove ghc's dependency on `ghc-heap`, since when we compile `stage0:ghc`, `stage1:ghc-internal` is not yet available. Thus, when we compile with the boot-compiler, we still depend on an older version of `ghc-heap`, and only use the modules from `ghc-internal`, if the `ghc-internal` version is recent enough. ------------------------- Metric Increase: T24602_perf_size T25046_perf_size_gzip T25046_perf_size_unicode T25046_perf_size_unicode_gzip size_hello_artifact size_hello_artifact_gzip size_hello_unicode size_hello_unicode_gzip ------------------------- These metric increases are unfortunate, they are most likely caused by the larger (literally in terms of lines of code) stack decoder implementation that are now linked into hello-word binaries.

When simplifying the RHS of a rule, or of a stable unfolding, we set the simplifier phase to a range of phases, computed from the activation of the RULE/unfolding activation, using the function 'phaseFromActivation'. The details are explained in Note [What is active in the RHS of a RULE?] in GHC.Core.Opt.Simplify.Utils. 2. The activation check for other rules and inlinings is then: does the activation of the other rule/inlining cover the whole phase range set in sm_phase? This continues to use the 'isActive' function, which now accounts for phase ranges. On the way, this commit also moves the exact-print SourceText annotation from the Activation datatype to the ActivationAnn type. This keeps the main Activation datatype free of any extra cruft.

To yield, we need to put the stack in a state such that when execution is resumed we are back to where we yielded from. Previously, a BKR_FUN could only head a function BCO because we only knew how to construct a valid stack for yielding from one -- simply add `apply_interp_info` + the BCO to resume executing. This is valid because the stack at the start of run_BCO is headed by that BCO's arguments. However, in case continuation BCOs (as per Note [Case continuation BCOs]), we couldn't easily reconstruct a valid stack that could be resumed because we dropped too soon the stack frames regarding the value returned (stg_ret) and received (stg_ctoi) by that continuation. This is especially tricky because of the variable type and size return frames (e.g. pointer ret_p/ctoi_R1p vs a tuple ret_t/ctoi_t2). The trick to being able to yield from a BRK_FUN at the start of a case cont BCO is to stop removing the ret frame headers eagerly and instead keep them until the BCO starts executing. The new layout at the start of a case cont. BCO is described by the new Note [Stack layout when entering run_BCO]. Now, we keep the ret_* and ctoi_* frames when entering run_BCO. A BRK_FUN is then executed if found, and the stack is yielded as-is with the preserved ret and ctoi frames. Then, a case cont BCO's instructions always SLIDE off the headers of the ret and ctoi frames, in StgToByteCode.doCase, turning a stack like | .... | +---------------+ | fv2 | +---------------+ | fv1 | +---------------+ | BCO | +---------------+ | stg_ctoi_ret_ | +---------------+ | retval | +---------------+ | stg_ret_..... | +---------------+ into | .... | +---------------+ | fv2 | +---------------+ | fv1 | +---------------+ | retval | +---------------+ for the remainder of the BCO. Moreover, this more uniform approach of keeping the ret and ctoi frames means we need less ad-hoc logic concerning the variable size of ret_tuple vs ret_p/np frames in the code generator and interpreter: Always keep the return to cont. stack intact at the start of run_BCO, and the statically generated instructions will take care of adjusting it. Unlocks BRK_FUNs at the start of case cont. BCOs which will enable a better user-facing step-out (#26042) which is free of the bugs the current BRK_ALTS implementation suffers from (namely, using BRK_FUN rather than BRK_ALTS in a case cont. means we'll never accidentally end up in a breakpoint "deeper" than the continuation, because we stop at the case cont itself rather than on the first breakpoint we evaluate after it). - - - - - ade3c1e6 by Rodrigo Mesquita at 2025-09-02T12:19:59-04:00 BRK_FUN with InternalBreakLocs for code-generation time breakpoints At the start of a case continuation BCO, place a BRK_FUN. This BRK_FUN uses the new "internal breakpoint location" -- allowing us to come up with a valid source location for this breakpoint that is not associated with a source-level tick. For case continuation BCOs, we use the last tick seen before it as the source location. The reasoning is described in Note [Debugger: Stepout internal break locs]. Note how T26042c, which was broken because it displayed the incorrect behavior of the previous step out when we'd end up at a deeper level than the one from which we initiated step-out, is now fixed. As of this commit, BRK_ALTS is now dead code and is thus dropped. Note [Debugger: Stepout internal break locs] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Step-out tells the interpreter to run until the current function returns to where it was called from, and stop there. This is achieved by enabling the BRK_FUN found on the first RET_BCO frame on the stack (See [Note Debugger: Step-out]). Case continuation BCOs (which select an alternative branch) must therefore be headed by a BRK_FUN. An example: f x = case g x of <--- end up here 1 -> ... 2 -> ... g y = ... <--- step out from here - `g` will return a value to the case continuation BCO in `f` - The case continuation BCO will receive the value returned from g - Match on it and push the alternative continuation for that branch - And then enter that alternative. If we step-out of `g`, the first RET_BCO on the stack is the case continuation of `f` -- execution should stop at its start, before selecting an alternative. (One might ask, "why not enable the breakpoint in the alternative instead?", because the alternative continuation is only pushed to the stack *after* it is selected by the case cont. BCO) However, the case cont. BCO is not associated with any source-level tick, it is merely the glue code which selects alternatives which do have source level ticks. Therefore, we have to come up at code generation time with a breakpoint location ('InternalBreakLoc') to display to the user when it is stopped there. Our solution is to use the last tick seen just before reaching the case continuation. This is robust because a case continuation will thus always have a relevant breakpoint location: - The source location will be the last source-relevant expression executed before the continuation is pushed - So the source location will point to the thing you've just stepped out of - Doing :step-local from there will put you on the selected alternative (which at the source level may also be the e.g. next line in a do-block) Examples, using angle brackets (<<...>>) to denote the breakpoint span: f x = case <<g x>> {- step in here -} of 1 -> ... 2 -> ...> g y = <<...>> <--- step out from here ... f x = <<case g x of <--- end up here, whole case highlighted 1 -> ... 2 -> ...>> doing :step-local ... f x = case g x of 1 -> <<...>> <--- stop in the alternative 2 -> ... A second example based on T26042d2, where the source is a do-block IO action, optimised to a chain of `case expressions`. main = do putStrLn "hello1" <<f>> <--- step-in here putStrLn "hello3" putStrLn "hello4" f = do <<putStrLn "hello2.1">> <--- step-out from here putStrLn "hello2.2" ... main = do putStrLn "hello1" <<f>> <--- end up here again, the previously executed expression putStrLn "hello3" putStrLn "hello4" doing step/step-local ... main = do putStrLn "hello1" f <<putStrLn "hello3">> <--- straight to the next line putStrLn "hello4" Finishes #26042 - - - - - c66910c0 by Rodrigo Mesquita at 2025-09-02T12:19:59-04:00 debugger: Re-use the last BreakpointId whole in step-out Previously, to come up with a location to stop at for `:stepout`, we would store the location of the last BreakpointId surrounding the continuation, as described by Note [Debugger: Stepout internal break locs]. However, re-using just the location from the last source breakpoint isn't sufficient to provide the necessary information in the break location. Specifically, it wouldn't bind any variables at that location. Really, there is no reason not to re-use the last breakpoint wholesale, and re-use all the information we had there. Step-out should behave just as if we had stopped at the call, but s.t. continuing will not re-execute the call. This commit updates the CgBreakInfo to always store a BreakpointId, be it the original one or the one we're emulating (for step-out).

PUSH_L 0 SLIDE 1 1 We do this often by generically constructing a tail call from a function atom that may be somewhere arbitrary on the stack. However, for the special case that the function can be found directly on top of the stack, as part of the arguments, it's plain redundant to push then slide it. In this commit we add a small optimisation to the generation of tailcalls in bytecode. Simply: lookahead for the function in the stack. If it is the first thing on the stack and it is part of the arguments which would be dropped as we entered the tail call, then don't push then slide it. In a simple example (T26042b), this already produced a drastic improvement in generated code (left is old, right is with this patch): ```diff 3c3 < 2025-07-29 10:14:02.081277 UTC --- > 2025-07-29 10:50:36.560949 UTC 160,161c160 < PUSH_L 0 < SLIDE 1 2 --- > SLIDE 1 1 164,165d162 < PUSH_L 0 < SLIDE 1 1 175,176c172 < PUSH_L 0 < SLIDE 1 2 --- > SLIDE 1 1 179,180d174 < PUSH_L 0 < SLIDE 1 1 206,207d199 < PUSH_L 0 < SLIDE 1 1 210,211d201 < PUSH_L 0 < SLIDE 1 1 214,215d203 < PUSH_L 0 < SLIDE 1 1 218,219d205 < PUSH_L 0 < SLIDE 1 1 222,223d207 < PUSH_L 0 < SLIDE 1 1 ... 600,601c566 < PUSH_L 0 < SLIDE 1 2 --- > SLIDE 1 1 604,605d568 < PUSH_L 0 < SLIDE 1 1 632,633d594 < PUSH_L 0 < SLIDE 1 1 636,637d596 < PUSH_L 0 < SLIDE 1 1 640,641d598 < PUSH_L 0 < SLIDE 1 1 644,645d600 < PUSH_L 0 < SLIDE 1 1 648,649d602 < PUSH_L 0 < SLIDE 1 1 652,653d604 < PUSH_L 0 < SLIDE 1 1 656,657d606 < PUSH_L 0 < SLIDE 1 1 660,661d608 < PUSH_L 0 < SLIDE 1 1 664,665d610 < PUSH_L 0 < SLIDE 1 1 ``` I also compiled lib:Cabal to bytecode and counted the number of bytecode lines with `find dist-newstyle -name "*.dump-BCOs" -exec wc {} +`: with unoptimized core: 1190689 lines (before) - 1172891 lines (now) = 17798 less redundant instructions (-1.5% lines) with optimized core: 1924818 lines (before) - 1864836 lines (now) = 59982 less redundant instructions (-3.1% lines) - - - - - 8b2c72c0 by L0neGamer at 2025-09-04T06:32:03-04:00 Add Control.Monad.thenM and Control.Applicative.thenA - - - - - 39e1b7cb by Teo Camarasu at 2025-09-04T06:32:46-04:00 ghc-internal: invert dependency of GHC.Internal.TH.Syntax on Data.Data This means that Data.Data no longer blocks building TH.Syntax, which allows greater parallelism in our builds.

Moreover, it removes all the now-redundant entries from `lib/settings` that are configured as part of a `Target` but were being written into `settings`. This makes it easier to support multiple targets from the same compiler (aka runtime retargetability). `ghc-toolchain` can be re-run many times standalone to produce a `Target` description for different targets, and, in the future, GHC will be able to pick at runtime amongst different `Target` files. This commit only makes it read the default `Target` configured in-tree or configured when installing the bindist. The remaining bits of `settings` need to be moved to `Target` in follow up commits, but ultimately they all should be moved since they are per-target relevant.

Luite Stegeman pushed to branch wip/ubxsumtag at Glasgow Haskell Compiler / GHC Commits: fb4497f1 by Luite Stegeman at 2025-09-11T16:22:03+02:00 Use slots smaller than word as tag for smaller unboxed sums This packs unboxed sums more efficiently by allowing Word8, Word16 and Word32 for the tag field if the number of constructors is small enough -

[Git][ghc/ghc][wip/T26315] 2 commits: Solve forall-constraints via an implication, again

Simon Peyton Jones pushed to branch wip/T26315 at Glasgow Haskell Compiler / GHC Commits: 84622fb0 by Simon Peyton Jones at 2025-09-11T14:11:52+01:00 Solve forall-constraints via an implication, again In this earlier commit: commit 953fd8f1dc080f1c56e3a60b4b7157456949be29 Author: Simon Peyton Jones <simon.peytonjones(a)gmail.com> Date: Mon Jul 21 10:06:43 2025 +0100 Solve forall-constraints immediately, or not at all I used a all-or-nothing strategy for quantified constraints (aka forall-constraints). But alas that fell foul of #26315, and #26376. So this MR goes back to solving a quantified constraint by turning it into an implication; UNLESS we are simplifying constraints from a SPECIALISE pragma, in which case the all-or-nothing strategy is great. See: Note [Solving a Wanted forall-constraint] Other stuff in this MR: * TcSMode becomes a record of flags, rather than an enumeration type; much nicer. * Some fancy footwork to avoid error messages worsening again (The above MR made them better; we want to retain that.) See `GHC.Tc.Errors.Ppr.pprQCOriginExtra`. - - - - - de2e7080 by Simon Peyton Jones at 2025-09-11T14:11:52+01:00 Add a test case for #26396 ...same bug ast #26315 - - - - - 46 changed files: - compiler/GHC/HsToCore/Binds.hs - compiler/GHC/Tc/Deriv/Utils.hs - compiler/GHC/Tc/Errors/Ppr.hs - compiler/GHC/Tc/Gen/Sig.hs - compiler/GHC/Tc/Solver.hs - compiler/GHC/Tc/Solver/Default.hs - compiler/GHC/Tc/Solver/Dict.hs - compiler/GHC/Tc/Solver/Equality.hs - compiler/GHC/Tc/Solver/InertSet.hs - compiler/GHC/Tc/Solver/Monad.hs - compiler/GHC/Tc/Solver/Solve.hs - compiler/GHC/Tc/Solver/Solve.hs-boot - compiler/GHC/Tc/Types/Constraint.hs - compiler/GHC/Tc/Types/Evidence.hs - compiler/GHC/Tc/Types/Origin.hs - compiler/GHC/Tc/Utils/Monad.hs - compiler/GHC/Tc/Zonk/TcType.hs - compiler/GHC/Tc/Zonk/Type.hs - testsuite/tests/backpack/should_fail/bkpfail11.stderr - testsuite/tests/backpack/should_fail/bkpfail43.stderr - + testsuite/tests/deriving/should_compile/T26396.hs - testsuite/tests/deriving/should_compile/all.T - testsuite/tests/deriving/should_fail/T12768.stderr - testsuite/tests/deriving/should_fail/T1496.stderr - testsuite/tests/deriving/should_fail/T21302.stderr - testsuite/tests/deriving/should_fail/T22696b.stderr - testsuite/tests/deriving/should_fail/T5498.stderr - testsuite/tests/deriving/should_fail/T7148.stderr - testsuite/tests/deriving/should_fail/T7148a.stderr - testsuite/tests/impredicative/T17332.stderr - testsuite/tests/quantified-constraints/T19690.stderr - testsuite/tests/quantified-constraints/T19921.stderr - testsuite/tests/quantified-constraints/T21006.stderr - testsuite/tests/roles/should_fail/RolesIArray.stderr - testsuite/tests/simplCore/should_compile/DsSpecPragmas.hs - testsuite/tests/simplCore/should_compile/DsSpecPragmas.stderr - testsuite/tests/typecheck/should_compile/T14434.hs - + testsuite/tests/typecheck/should_compile/T26376.hs - testsuite/tests/typecheck/should_compile/all.T - testsuite/tests/typecheck/should_fail/T15801.stderr - testsuite/tests/typecheck/should_fail/T19627.stderr - testsuite/tests/typecheck/should_fail/T20666.stderr - testsuite/tests/typecheck/should_fail/T20666a.stderr - testsuite/tests/typecheck/should_fail/T20666b.stderr - testsuite/tests/typecheck/should_fail/T22912.stderr - testsuite/tests/typecheck/should_fail/T23427.stderr The diff was not included because it is too large.
