  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
  same thing redundant.

  ghc-internal: Remove GHC.Internal.Data.Eq
  
  It served no purpose other than being a re-export.

  ghc-internal: Refine GHC.Internal.Base imports
  
  Removed re-exports from GHC.Internal.Base. This reveals some modules
  that don't actually use anything *defined* in GHC.Internal.Base, and
  that can be pushed down a little in the import graph.
  
  Replaced most imports of GHC.Internal.Base with non-wildcard imports
  from modules where the identifiers are actually defined.

  ci: clone, don't copy when creating the cabal cache
  
  Also removed WINDOWS_HOST variable detected via uname - we now just
  check whether the CI job has windows in its name. This works because we
  only ever care about it if the respective job is not a cross job. We
  also statically detect darwin cross jobs in the same way. We only ever have
  darwin -> darwin cross jobs so this is enough to detect the host
  reliably.

  The size of the x86_64 hello artifact is not stable which results in flaky testruns.

  ghci: Mention active language edition in startup banner
  
  Per GHC proposal 632, this makes the GHCi startup banner include
  the active language edition, plus an indication of whether this
  was the default (as opposed to being explicitly selected via an
  option such as `-XGHC2024`). For example:
  
  ```
  $ ghci
  GHCi, version 9.14.1: https://www.haskell.org/ghc/  :? for help
  Using default language edition: GHC2024
  ghci>
  ```
  
  Fixes #26037.

  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).
  
  Fixes #26686

  rts: opportunistically grow the MutableByteArray# in-place in resizeMutableByteArray#
  
  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.
  
  Fixes #26852

  Branchless unpacking for enumeration types
  
  Change unpacking for enumeration types to go to Word8#/Word16#/Word#
  directly instead of going through an intermediate unboxed sum. This
  allows us to do a branchless conversion using DataToTag and TagToEnum.

  bytecode: Carefully SLIDE off the end of a stack chunk
  
  The SLIDE bytecode instruction was not checking for stack chunk
  boundaries and could corrupt the stack underflow frame, leading
  to crashes.
  
  We add a check to use safe writes if we cross the chunk boundary
  and also handle stack underflow if Sp is advanced past the underflow
  frame.

  ghci: serialize BCOByteArray buffer directly when possible
  
  This patch changes the `Binary` instances of `BCOByteArray` to
  directly serialize the underlying buffer when possible, while also
  taking into account the issue of host-dependent `Word` width. See
  added comments and amended `Note [BCOByteArray serialization]` for
  detailed explanation. Closes #27020.

  Replace BigInt-based implementations of quotWord32, remWord32,
  quotRemWord32, quotRem2Word32, quotWord64, remWord64, quotInt64, and
  remInt64 with pure Number (double/integer) arithmetic to avoid the
  overhead of BigInt promotion.

  hadrian: don't compile RTS with -Winline
  
  This patch removes `-Winline` from cflags when compiling the RTS,
  given that:
  
  1. It generates a huge pile of spam and hurts developer experience
  2. Whether inlining happens is highly dependent on toolchains,
     flavours, etc, and it's not really an issue to fix if inlining
     doesn't happen; it's a hint to the C compiler anyway.
  
  Fixes #27060.
