  base: don't expose GHC.Num.{BigNat, Integer, Natural}
  
  We no longer expose GHC.Num.{BigNat, Integer, Natural} from base instead users should get these modules from ghc-bignum.
  We make this change to insulate end users from changes to GHC's implementation of big numbers.
  Implements CLC proposal 359: https://github.com/haskell/core-libraries-committee/issues/359

  hadrian: remove RTS options in ghc-in-ghci flavour
  
  This patch removes the RTS options passed to ghc in ghc-in-ghci
  flavour, to workaround command line argument handling issue in
  hls/hie-boot that results in `-O64M` instead of `+RTS -O64M -RTS`
  being passed to ghc. It's not a hadrian bug per se, since ghc's own
  ghc-in-ghci multi repl works fine, but we should still make sure HLS
  works. Closes #26801.

  This reverts commit 1e5752f64a522c4025365856d92f78073a7b3bba. The

  and present since 1.3.9.0, and hadrian directory lower bound is
  1.3.9.0, so we can revert our own in house hack now.

  rts: fix typo in TICK_ALLOC_RTS
  
  This patch fixes a typo in the `TICK_ALLOC_RTS` macro, the original
  `bytes` argument was silently dropped. The Cmm code has its own
  version of `TICK_ALLOC_RTS` not affected by this typo, it affected the
  C RTS, and went unnoticed because the variable `n` happened to also be
  available at its call site. But the number was incorrect. Also fixes
  its call site since `WDS()` is not available in C.

  Make the implicit-parameter class have representational role
  
  This MR addresses #26737, by making the built-in class IP
  have a representational role for its second parameter.
  
  See Note [IP: implicit parameter class] in
    ghc-internal:GHC.Internal.Classes.IP
  
  In fact, IP is (unfortunately, currently) exposed by
  base:GHC.Base, so we ran a quick CLC proposal to
  agree the change:
    https://github.com/haskell/core-libraries-committee/issues/385
  
  Some (small) compilations get faster because they only need to
  load (small) interface file GHC.Internal.Classes.IP.hi,
  rather than (large) GHC.Internal.Classes.hi.

  testsuite: avoid re.sub in favor of simple string replacements
  
  This patch refactors the testsuite driver and avoids the usage of
  re.sub in favor of simple string replacements when possible. The
  changes are not comprehensive, and there are still a lot of re.sub
  usages lingering around the tree, but this already addresses a major
  performance bottleneck in the testsuite driver that might has to do
  with quadratic or worse slowdown in cpython's regular expression
  engine when handling certain regex patterns with large strings.
  Especially on i386, and i386 jobs are the bottlenecks of all full-ci
  validate pipelines!
  
  Here are the elapsed times of testing x86_64/i386 with -j48 before
  this patch:
  
  x86_64: `Build completed in 6m06s`
  i386: `Build completed in 1h36m`
  
  And with this patch:
  
  x86_64: `Build completed in 4m55s`
  i386: `Build completed in 4m23s`
  
  Fixes #26786.

  hadrian: add missing notCross predicate for stage0 -O0
  
  There are a few hard-coded hadrian args that pass -O0 when compiling
  some heavy modules in stage0, which only makes sense when not
  cross-compiling and when cross-compiling we need properly optimized
  stage0 packages. So this patch adds the missing `notCross` predicate
  in those places.

  rts: avoid Cmm loop to initialize Array#/SmallArray#
  
  Previously, `newArray#`/`newSmallArray#` called an RTS C function to
  allocate the `Array#`/`SmallArray#`, then used a Cmm loop to
  initialize the elements. Cmm doesn't have native for-loop so the code
  is a bit awkward, and it's less efficient than a C loop, since the C
  compiler can effectively vectorize the loop with optimizations.
  
  So this patch moves the loop that initializes the elements to the C
  side. `allocateMutArrPtrs`/`allocateSmallMutArrPtrs` now takes a new
  `init` argument and initializes the elements if `init` is non-NULL.

  Fix testsuite run for +ipe flavour transformer
  
  This patch makes the +ipe flavour transformer pass the entire
  testsuite:
  
  - An RTS debug option `-DI` is added, the IPE trace information is now
    only printed with `-DI`. The test cases that do require IPE trace
    are now run with `-DI`.
  - The testsuite config option `ghc_with_ipe` is added, enabled when
    running the testsuite with `+ipe`, which skips a few tests that are
    sensitive to eventlog output, allocation patterns etc that can fail
    under `+ipe`.
  
  This is the first step towards #26799.

  ci: only push perf notes on master/release branches
  
  This patch fixes push_perf_notes logic in ci.sh to only push perf
  notes on master/release branches. We used to unconditionally push perf
  notes even in MRs, but the perf numbers in the wip branches wouldn't
  be used as baseline anyway, plus this is causing a space leak in the
  ghc-performance-notes repo. See #25317 for the perf notes repo size
  problem.

  This contribution implements CLC proposal #369. It adds operations for

  ci: update darwin boot ghc to 9.10.3
  
  This patch updates darwin boot ghc to 9.10.3, along with other related
  updates, and pays off some technical debt here:
  
  - Update `nixpkgs` and use the `nixpkgs-25.05-darwin` channel.
  - Update the `niv` template.
  - Update LLVM to 21 and update `llvm-targets` to reflect LLVM 21
    layout changes for arm64/x86_64 darwin targets.
  - Use `stdenvNoCC` to prevent nix packaged apple sdk from being used
    by boot ghc, and manually set `DEVELOPER_DIR`/`SDKROOT` to enforce
    the usage of system-wide command line sdk for macos.
  - When building nix derivation for boot ghc, run `configure` via the
    `arch` command so that `configure` and its subprocesses pick up the
    manually specified architecture.
  - Remove the previous horrible hack that obliterates `configure` to
    make autoconf test result in true. `configure` now properly does its
    job.
  - Remove the now obsolete configure args and post install settings
    file patching logic.
  - Use `scheme-small` for texlive to avoid build failures in certain
    unused texlive packages, especially on x86_64-darwin.

  Evaluate backtraces for "error" exceptions at the moment they are thrown
  
  See Note [Capturing the backtrace in throw] and
  Note [Hiding precise exception signature in throw] which explain the
  implementation.
  
  This commit makes `error` and `throw` behave the same with regard to
  backtraces. Previously, exceptions raised by `error` would not contain
  useful IPE backtraces.
  
  I did try and implement `error` in terms of `throw` but it started to
  involve putting diverging functions into hs-boot files, which seemed to
  risky if the compiler wouldn't be able to see if applying a function
  would diverge.

  Improve defaulting of representational equalities
  
  This commit makes the defaulting of representational equalities, introduced
  in 1e53277a, a little bit more robust. Now, instead of calling the eager
  unifier, it calls the full-blown constraint solver, which means that it can
  handle some subtle situations, e.g. involving functional dependencies and
  type-family injectivity annotations, such as:
  
    type family F a = r | r -> a
    type instance F Int = Bool
  
    [W] F beta ~R Bool

  Improve errors for unsolved representational equalities
  
  This commit adds a new field of CtLoc, CtExplanations, which allows the
  typechecker to leave some information about what it has done. For the moment,
  it is only used to improve error messages for unsolved representational
  equalities. The typechecker will now accumulate, when unifying at
  representational role:
  
    - out-of-scope newtype constructors,
    - type constructors that have nominal role in a certain argument,
    - over-saturated type constructors,
    - AppTys, e.g. `c a ~R# c b`, to report that we must assume that 'c' has
      nominal role in its parameters,
    - data family applications that do not reduce, potentially preventing
      newtype unwrapping.
  
  Now, instead of having to re-construct the possible errors after the fact,
  we simply consult the CtExplanations field.
  
  Additionally, this commit modifies the typechecker error messages that
  concern out-of-scope newtype constructors. The error message now depends
  on whether we have an import suggestion to provide to the user:
  
    - If we have an import suggestion for the newtype constructor,
      the message will be of the form:
  
        The data constructor MkN of the newtype N is out of scope
        Suggested fix: add 'MkN' to the import list in the import of 'M'
  
    - If we don't have any import suggestions, the message will be
      of the form:
  
        NB: The type 'N' is an opaque newtype, whose constructor is hidden

  Fix two bugs in short-cut constraint solving
  
  There are two main changes here:
  
  * Use `isSolvedWC` rather than `isEmptyWC` in `tryShortCutSolver`
    The residual constraint may have some fully-solved, but
    still-there implications, and we don't want them to abort short
    cut solving!  That bug caused #26805.
  
  * In the short-cut solver, we abandon the fully-solved residual
    constraint; but we may thereby lose track of Givens that are
    needed, and either report them as redundant or prune evidence
    bindings that are in fact needed.
  
    This bug stopped the `constraints` package from compiling;
    see the trail in !15389.
  
  The second bug led me to (another) significant refactoring
  of the mechanism for tracking needed EvIds.   See the new
     Note [Tracking needed EvIds] in GHC.Tc.Solver.Solve
  It's simpler and much less head-scratchy now.
  
  Some particulars:
  
  * An EvBindsVar now tracks NeededEvIds
  
  * We deal with NeededEvIds for an implication only when it is
    fully solved.  Much simpler!
  
  * `tryShortCutTcS` now takes a `TcM WantedConstraints` rather than
    `TcM Bool`, so that is can plumb the needed EvIds correctly.
  
  * Remove `ic_need` and `ic_need_implic` from Implication (hooray),
    and add `ics_dm` and `ics_non_dm` to `IC_Solved`.
  
  Pure refactor
  * Shorten data constructor `CoercionHole` to `CH`, following
    general practice in GHC.
  * Rename `EvBindMap` to `EvBindsMap` for consistency

  Remove `GHC.Desugar` from `base`
  
  `GHC.Desugar` was deprecated and should have been removed in GHC 9.14.
  However, the removal was forgotten, although there was a code block that
  was intended to trigger a compilation error when the GHC version in use
  was 9.14 or later. This code sadly didn’t work, because the
  `__GLASGOW_HASKELL__` macro was misspelled as `__GLASGOW_HASKELL`.

  determinism: Use deterministic map for Strings in TyLitMap
  
  When generating typeable evidence the types we need evidence for all
  cached in a TypeMap, the order terms are retrieved from a type map
  determines the order the bindings appear in the program.
  
  A TypeMap is quite diligent to use deterministic maps, apart from in the
  TyLitMap, which uses a UniqFM for storing strings, whose ordering
  depends on the Unique of the FastString.
  
  This can cause non-deterministic .hi and .o files.
  
  An unexpected side-effect is the error message but RecordDotSyntaxFail8
  changing. I looked into this with Sam and this change caused the
  constraints to be solved in a different order which results in a
  slightly different error message. I have accepted the new test, since
  the output before was non-deterministic and the new output is consistent
  with the other messages in that file.

    * Other `Binary` instances are orphans to be migrated later.
  
  The `OverlapMode` data-type is given a TTG extension point.
  The `OverlapFlag` data-type, which depends on `OverlapMode`,
  is updated to support `OverlapMode` with a GHC "pass" type paramerter.
  In order to avoid module import cycles, `OverlapMode` and `OverlapFlag`
  are migrated to new modules (no way around this).
  
    * Migrated `OverlapMode` to new module `Language.Haskell.Syntax.Overlap`
    * Migrated `OverlapFlag` to new module `GHC.Hs.Decls.Overlap`

  Refactor: merge HsMultilineString into HsString (#26860)
  
  Before this patch, HsLit defined two separate constructors to represent
  single-line and multi-line strings:
  
  	data HsLit x
  	  ...
  	  | HsString (XHsString x) FastString
  	  | HsMultilineString (XHsMultilineString x) FastString
  
  I found this to be an unnecessary complication and an obstacle to unifying
  HsLit with HsTyLit. Now we use HsString for both kinds of literals.
  
  One user-facing change here is `ppr (HsString st s)` behaving differently for
  single-line strings containing newlines:
  
  	x = "first line \
  	    \asdf\n\
  	    \second line"
  
  Previously, the literal was fed to `ftext` with its newlines, producing an
  ill-formed SDoc. This issue is now addressed by using `split` for both
  single-line and multi-line strings:
  
  	vcat $ map text $ split '\n' (unpackFS src)
  
  See the parser/should_fail/T26860ppr test.
  
  In addition (and unrelatedly to the main payload of this patch),
  drop the unused pmPprHsLit helper.

  ExplicitLevelImports: check staging for types just like for values
  
  Previously, imported types were entirely exempted from staging checks as
  the implicit stage persistance assumed to be all imported types to be
  well staged. ExplicitLevelImports' change specification, however, does
  not do such an exemption. Thus we want to introduce such a check, just
  like we have for values.
  ExplicitLevelImports does not, however, talk about local names - from
  its perspective, we could theoretically keep treating locally introduced
  types specially - e.g. an ill-staged used in a quote would only emit a
  warning, not an error. To allow for a potential future migration away
  from such wrinkles as the staging check in notFound
  (see  Note [Out of scope might be a staging error]) we consistently do
  the strict staging check that we also do for value if ExplicitLevelImports
  is on.

  Remove `extra_src_files` variable from `testsuite/driver/testlib.py`
  
  While reading through the test harness code, I noticed this variable
  with a TODO attached that referenced #12223.  Although that bug is
  closed, it strongly implied that this special-case variable that only
  affected a single test was expected to be removed at some point.
  
  I also looked at 3415bcaa0b1903b5e12dfaadb5b774718e406eab---where it
  was added---whose commit message suggested that it would have been
  desirable to remove it, but that there were special circumstances that
  meant it had to remain (though it doesn't elucidate what those special
  circumstances are).
  
  However, the special circumstances were mentioned as if the test was
  in a different location than is currently is, so I decided to try
  changing the test to use the standard `extra_files` mechanism, which
  works in local testing.
  
  This also seems like a reasonable time to remove the script that was
  originally used in the transition, since it doesn't really serve a
  purpose anymore.

  b8307eab80c5809df5405d76c822bf86877f5960 that removed C99 check in
  autoconf/ghc-toolchain. Now we:
  
  - No longer re-implement `FP_SET_CFLAGS_C11` similar to
    `FP_SET_CFLAGS_C99` in the past, since autoconf doesn't provide a
    convenient `AC_PROG_CC_C11` function. ghc-toolchain will handle it
    anyway.
  - The Cmm CPP C99 check is relanded and repurposed for C11.
  - The C99 logic in ghc-toolchain is relanded and repurposed for C11.
  - The C99 check in Stg.h is corrected to check for C11. The obsolete
    _ISOC99_SOURCE trick is dropped.
  - Usages of `-std=gnu99` in the testsuite are corrected to use
    `-std=gnu11`.

  Simplify the treatment of static forms
  
  This MR implements GHC proposal 732: simplify static forms,
     https://github.com/ghc-proposals/ghc-proposals/pull/732
  thereby addressing #26556.
  
  See `Note [Grand plan for static forms]` in GHC.Iface.Tidy.StaticPtrTable
  
  The main changes are:
  
  * There is a new, simple rule for (static e), namely that the free
    term variables of `e` must be bound at top level.  The check is
    done in the `HsStatic` case of `GHC.Rename.Expr.rnExpr`
  
  * That in turn substantially simplifies the info that the typechecker
    carries around in its type environment.  Hooray.
  
  * The desugarer emits static bindings to top level directly; see the
    `HsStatic` case of `dsExpr`.
  
  * There is no longer any special static-related magic in the FloatOut
    pass.  And the main Simplifier pipeline no longer needs a special case
    to run FloatOut even with -O0.  Hooray.
  
  All this forced an unexpected change to the pattern match checker. It
  recursively invokes the main Hs desugarer when it wants to take a look
  at a term to spot some special cases (notably constructor applications).
  We don't want to emit any nested (static e) bindings to top level a
  second time!  Yikes.
  
  That forced a modest refactor in GHC.HsToCore.Pmc:
  
  * The `dsl_nablas` field of `DsLclEnv` now has a `NoPmc` case, which says
    "I'm desugaring just for pattern-match checking purposes".
  
  * When that flag is set we don't emit static binds.
  
  That in turn forces a cascade of refactoring, but the net effect is an
  improvement; less risk of duplicated (even exponential?) work.
  
  See Note [Desugaring HsExpr during pattern-match checking].

  ghc-internal: avoid depending on GHC.Internal.Exts
  
  This module is mostly just re-exports. It made sense as a user-facing

  - move considerAccessible to GHC.Internal.Magic
  
  Previously it lived in GHC.Internal.Exts, but it really deserves to live
  along with the other magic function, which are already re-exported from .Exts
  
  - move maxTupleSize to GHC.Internal.Tuple

  Fix linking against libm by moving the -lm option
  
  For those systems that need -lm for getting math functions, this is
  currently added on the link line very early, before the object files being
  linked together. Newer toolchains enable --as-needed by default, which means
  -lm is ignored at that point because no object requires a math function
  yet. With such toolchains, we thus have to add -lm after the objects, so the
  linker actually includes libm in the link.

  ghc-internal: avoid depending on GHC.Internal.Control.Monad.Fix
  
  This module contains the definition of MonadFix, since we want an
  instance for IO, that instance requires a lot of machinery and we want
  to avoid an orphan instance, this will naturally be quite high up in the
  dependency graph.
  
  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.
  
  Resolves #26875

  Refine the imports of `System.IO.OS`
  
  Commit 68bd08055594b8cbf6148a72d108786deb6c12a1 replaced the
  `GHC.Internal.Data.Bool` import by a `GHC.Internal.Base` import.
  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.

  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.
  
  Closes #26951.

  Check for negative type literals in the type checker (#26861)
  
  GHC disallows negative type literals (e.g., -1), as tested by T8306 and
  T8412. 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.

  Make list comprehension completely non-linear
  
  Fixes #25081
  
  From the note:
  
  The usefulness of list comprehension in conjunction with linear types is dubious.
  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.

  Drop HsTyLit in favor of HsLit (#26862, #25121)
  
  This patch is a small step towards unification of HsExpr and HsType,
  taking care of literals (HsLit) and type literals (HsTyLit).
  
  Additionally, it improves error messages for unsupported type literals,
  such as unboxed or fractional literals (test cases: T26862, T26862_th).
  
  Changes to the AST:
  
  * Use HsLit           where HsTyLit   was previously used
  * Use HsChar          where HsCharTy  was previously used
  * Use HsString        where HsStrTy   was previously used
  * Use HsNatural (NEW) where HsNumTy   was previously used
  * Use HsDouble  (NEW) to represent unsupported fractional type literals
  
  Changes to logic:
  
  * Parse unboxed and fractional type literals (to be rejected later)
  
  * Drop the check for negative literals in the renamer (rnHsTyLit)
    in favor of checking in the type checker (tc_hs_lit_ty)
  
  * Check for invalid type literals in TH (repTyLit) and report
    unrepresentable literals with ThUnsupportedTyLit
  
  * Allow negative type literals in TH (numTyLit). This is fine as
    these will be taken care of at splice time (test case: T8306_th)

  Clean up join points, casts & ticks
  
  This commit shores up the logic dealing with casts and ticks occurring
  in between a join point binding and a jump.
  
  Fixes #26642 #26929 #26693
  Makes progress on #14610 #26157 #26422
  
  Changes:
  
    - Remove 'GHC.Types.Tickish.TickishScoping' in favour of simpler
      predicates 'tickishHasNoScope'/'tickishHasSoftScope', as things were
      before commit 993975d3. This makes the code easier to read and
      document (fewer indirections).
  
    - Introduce 'canCollectArgsThroughTick' for consistent handling of
      ticks around PrimOps and other 'Id's that cannot be eta-reduced.
      See overhauled Note [Ticks and mandatory eta expansion].
  
    - New Note [JoinId vs TailCallInfo] in GHC.Core.SimpleOpt that explains
      robustness of JoinId vs fragility of TailCallInfo.
  
    - Allow casts/non-soft-scoped ticks to occur in between a join point
      binder and a jump, but only in Core Prep.
      See Note [Join points, casts, and ticks] and
      Note [Join points, casts, and ticks... in Core Prep]
      in GHC.Core.Opt.Simplify.Iteration.
  
      Also update Core Lint to account for this.
      See Note [Linting join points with casts or ticks] in GHC.Core.Lint.
  
    - Update 'GHC.Core.Utils.mergeCaseAlts' to avoid pushing a cast in
      between a join point binding and its jumps. This fixes #26642.
      See the new (MC5) and (MC6) in Note [Merge Nested Cases].
  
    - Update float out to properly handle source note ticks. They are now
      properly floated out instead of being discarded.
      This increases the number of ticks in certain tests with -g.
  
  Test cases: T26642 and TrickyJoins.
  
  Metric increase due to more source note ticks with -g:

  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.

  For context, see the existing Note [Grand plan for Typeable]
  and the Note [NOINLINE on generated Typeable bindings] added in the
  subsequent commit.
  
  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.

  Return a valid pointer in advanceStackFrameLocationzh
  
  When there is no next stack chunk, `advanceStackFrameLocationzh` used to
  return NULL in the pointer-typed StackSnapshot# result slot.
  
  Even though the caller treats that case as "no next frame", the result is
  still materialized in a GC-visible pointer slot. If a GC observes the raw
  NULL there, stack decoding can crash.
  
  Fix this by ensuring the dead pointer slot contains a valid closure
  pointer. Also make the optional result explicit by returning an unboxed
  sum instead of a tuple with a separate tag.

  DmdAnal: Take stable unfoldings into account when determining argument demands
  
  Previously, demand analysis only looked at the RHS to compute argument demands.
  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.
  
  Fixes #26416.

  Stg/Unarise: constant-folding during unarisation (#25650)
  
  When building an unboxed sum from a literal argument, mkUbxSum
  previously emitted a runtime cast via `case primop [lit] of var -> ...`.
  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.

  Add regression test for #2057
  
  Test that GHC stops after an interface-file error instead of
  continuing into the linker.
  
  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.

  Before this patch, an exception thrown in the `onException` handler
  would loose track of where the original exception was thrown.
  
  ```

  main :: IO ()
  main = failingAction `onException` failingCleanup
    where
      failingAction = throwIO (ErrorCall "outer failure")
      failingCleanup = throwIO (ErrorCall "cleanup failure")
  ```
  
  would report
  
  ```

  ```
  
  notice that the "outer failure" exception is not present in the error
  message.
  
  With this patch, any exception thrown is in the handler is annotated

  Introduce `-fimport-loaded-targets` GHCi flag
  
  This new flag automatically adds all loaded targets to the GHCi session
  by adding an `InteractiveImport` for the loaded targets.
  
  By default, this flag is disabled, as it potentially increases memory-usage.
  
  This interacts with the flag `-fno-load-initial-targets` as follows:
  
  * If no module is loaded, no module is added as an interactive import.
  * If a reload loads up to a module, all loaded modules are added as
    interactive imports.
  * Unloading modules removes them from the interactive context.
  
  Fixes #26866 by rendering the use of a `-ghci-script` to achieve the

  Improve incomplete record selector warnings
  
  This commit stops GHC from emitting spurious incomplete record selector
  warnings for bare selectors/projections such as .fld
  
  There are two places we currently emit incomplete record selector
  warnings:
  
    1. 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).

  Following !15234, this patch improves `resizeMutableByteArray#` memory
  efficiency by growing the `MutableByteArray#` in-place if possible,
  addressing an old todo comment here. Also adds a new test case
  `resizeMutableByteArrayInPlace` that stresses this behavior.

  Change representation of floating point literals
  
  This commit changes the representation of floating point literals
  throughough the compiler, in particular in Core and Cmm.
  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.
  
  Fixes #8364 #9811 #18897 #21227
  Progress towards #26919

  compiler/ffi: Collapse void pointer chains in capi wrappers
  
  New gcc/clang treat -Wincompatible-pointer-types as an error by
  default. Since C only allows implicit conversion from void*, not void**,
  capi wrappers for functions taking e.g. abstract** would fail to compile
  when the Haskell type Ptr (Ptr Abstract) was naively translated to void**.
  
  Collapse nested void pointers to a single void* when the pointee type
  has no known C representation.

  Implement basic value range analysis (#25718)
  
  Perform basic value range analysis to try to determine at compile time
  the result of the application of some comparison primops (ltWord#, etc.).
  
  This subsumes the built-in rewrite rules used previously to check if one
  of the comparison argument was a bound (e.g. (x :: Word8) <= 255 is
  always True). Our analysis is more powerful and handles type
  conversions: e.g. word8ToWord x <= 255 is now detected as always True too.
  
  We also use value range analysis to filter unreachable alternatives in
  case-expressions. To support this, we had to allow case-expressions for
  primitive types to not have a DEFAULT alternative (as was assumed before
  and checked in Core lint).

  rts: Align stack to 64-byte boundary in StgRun on x86
  
  When LLVM spills AVX/AVX-512 vector registers to the stack, it requires
  32-byte (__m256) or 64-byte (__m512) alignment. 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: Float Generics to near top of module graph
  
  We remove GHC.Internal.Generics from the critical path of the
  `ghc-internal` module graph. 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.

  AArch64: fix MOVK regUsageOfInstr to mark dst as both read and written
  
  MOVK (move with keep) modifies only a 16-bit slice of the destination

  rts: forward clone-stack messages after TSO migration
  
  MSG_CLONE_STACK assumed that the target TSO was still owned by the
  capability that received the message. 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.

  Fix race condition between flushEventLog and start/endEventLogging.
  
  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.

  Fix build with werror on glibc 2.43.
  
  We've been defining `_XOPEN_SOURCE` and `_POSIX_C_SOURCE` to the same
  values as defined in glibc prior to 2.43. But in 2.43, glibc changes
  them to new values, which means we get a warning when redefining them.
  By `#undef`ing them first, we no longer get a warning.
  
  Closes #27076.

  Support arbitrary size unboxed tuples in bytecode
  
  This stores the size (number of words on the stack) of the next
  expected tuple in the TSO, ctoi_spill_size field, eliminating
  the need of stg_ctoi_tN frames for each size.
  
  Note: On 32 bit platform there is still a bytecode tuple size
  limit of 255 words on the stack.

  Extend HsExpr with the StarIsType syntax (#26587, #26967)
  
  This patch allows kinds of the form `k -> *` and `* -> k` to occur in
  expression syntax, i.e. to be used as required type arguments.
  
  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 is more limited than the full StarIsType syntax, but has the nice
    property of not conflicting with the multiplication operator `a * b`.
  
  Test case: T26967 T26967_tyop

  STM: don't create a transaction in the rhs of catchRetry# (#26028)
  
  We don't need to create a transaction for the rhs of (catchRetry#)
  because contrary to the lhs we don't need to abort it on retry. Moreover
  it is particularly harmful if we have code such as (#26028):
  
    let cN = readTVar vN >> retry
        tree = c1 `orElse` (c2 `orElse` (c3 `orElse` ...))
    atomically tree
  
  Because it will stack transactions for the rhss and the read-sets of all
  the transactions will be iteratively merged in O(n^2) after the
  execution of the most nested retry.
  
  This is the second attempt at implementing this. The first attempt
  triggered segfaults (#26291) and has been reverted.

  Windows: remove StgAsyncIOResult and fix crash/leaks
  
  In stg_block_async{_void}, a stack slot was reserved for
  an StgAsyncIOResult. 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.
  
  We fix this by removing the StgAsyncIOResult altogether and writing
  the result directly to the stack.
  
  Fixes #26341

  Fix several oversights in hsExprType
  
  This commit fixes several oversights in GHC.Hs.Syn.Type.hsExprType:
  
    - The 'RecordCon' case was returning the type of the constructor,
      instead of the constructor application. 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.
  
  Fixes #26910

  Infix holes in types (#11107)
  
  This patch introduces several improvements that follow naturally from
  refactoring HsOpTy to represent the operator as an HsType, aligning it
  with the approach taken by OpApp and HsExpr.
  
  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.  For example,
  
       ppr_infix_ty       <=> ppr_infix_expr
       get_tyop           <=> get_op
       lookupTypeFixityRn <=> lookupExprFixityRn
             (the latter is factored out from rnExpr)
