Move most of the `Numeric` implementation into `base`
The `showHex` operation and the `showIntAtBase` operation, which
underlies it, are kept in `GHC.Internal.Numeric`, because `showHex` is
used in a few places in `ghc-internal`; everything else is moved.

hadrian: fix ghc-in-ghci flavour stage0 shared libraries
This patch fixes missing stage0 shared libraries in hadrian
ghc-in-ghci flavour, which was accidentally dropped in
669d09f950a6e88b903d9fd8a7571531774d4d5d and resulted in a regression
in HLS support on linux/macos. Fixes #27057.

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.

hadrian: remove redundant library/rts ways definitions from stock flavours
This patch removes redundant library/rts ways definitions from stock

ghc-internal: move bits Weak of finalizer interface to base
We move parts of the Weak finalizer interface to `base` only the parts
that the RTS needs to know about are kept in `ghc-internal`.
This lets us then prune our imports somewhat and get rid of some SOURCE imports.
Resolves #26985

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.
Test: codeGen/should_compile/T25650

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.

hadrian: bump index state & bootstrap plans
This patch bumps hadrian index state & bootstrap plans:
- The updated index state allows bootstrapping from 9.14 without cabal
allow-newer hacks
- The updated bootstrap plans all contain shake-0.19.9 containing
important bugfix, allowing a subsequent patch to bump shake bound to
ensure the bugfix is included

ci: add ghc 9.14.1 to bootstrap matrix
This patch adds ghc 9.14.1 to bootstrap matrix, so that we test
bootstrapping from ghc 9.14.1.

T17912: wait for opener thread to block before killing it (#24739)
Instead of a fixed 1000ms delay, poll threadStatus until the opener
thread is in BlockedOnForeignCall, ensuring killThread only fires once
the thread is provably inside the blocking open() syscall. This prevents
the test from accidentally passing on Windows due to scheduling races.

template-haskell: fix redundant import in Language.Haskell.TH.Quote
This patch fixes a redundant import in `Language.Haskell.TH.Quote`
that causes a ghc build failure when bootstrapping from 9.14 with
validate flavours. Fixes #27014.

Add a cumulative gc_sync_elapsed_ns counter to GHC.Internal.Stats
This makes it possible to get an accurate view of time spent in sync
phase when using prometheus-style sampling. Previously this was only
available for the most recent GC.
This intentionally leaves GHC.Stats API unchanged since it is marked as
deprecated, and API changes there require CLC approval.
Fixes #26944

configure: make $LLVMAS default to $CC when $CcLlvmBackend is YES
This patch changes the $LLVMAS detection logic in configure so that
when it's not manually specified by the user, it defaults to $CC if
$CcLlvmBackend is YES. It's a more sensible default than auto-detected
clang from the environment, especially when cross-compiling, $CC as
the cross target's LLVM assembler is more compatible with the use case
than the system-wide clang. Fixes #26769.

exceptions: annotate onException continuation with WhileHandling
Before this patch, an exception thrown in the `onException` handler
would loose track of where the original exception was thrown.
```
import Control.Exception
main :: IO ()
main = failingAction `onException` failingCleanup
where
failingAction = throwIO (ErrorCall "outer failure")
failingCleanup = throwIO (ErrorCall "cleanup failure")
```
would report
```
T28399: Uncaught exception ghc-internal:GHC.Internal.Exception.ErrorCall:
cleanup failure
HasCallStack backtrace:
throwIO, called at T28399.hs:<line>:<column> in <package-id>:Main
```
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
with WhileHandling. The resulting message looks like
```
T28399: Uncaught exception ghc-internal:GHC.Internal.Exception.ErrorCall:
cleanup failure
While handling outer failure
HasCallStack backtrace:
throwIO, called at T28399.hs:7:22 in main:Main
```

The current ci-images revision was a commit on the WIP branch of
https://gitlab.haskell.org/ghc/ci-images/-/merge_requests/183, and
it's not on the current ci-images master branch. This patch fixes the
image revision to use the current tip of ci-images master.

Revert "hadrian/build-cabal: Better respect and utilize -j"
This reverts commit eab3dbba79650e6046efca79133b4c0a5257613d.
While it's neat this currently isn't well supported on all platforms.
It's time will come, but for now I'm reverting this to avoid issues for
users on slightly unconvential platforms.
This will be tracked at #26977.

Configure: Fix check for --target support in stage0 CC
The check FP_PROG_CC_LINKER_TARGET used $CC unconditionally to check for
--target support. However this fails for the stage0 config where the C
compiler used is not $CC but $CC_STAGE0.
Since we already pass the compiler under test into the macro I simply
changed it to use that instead.
Fixes #26999

Move most of the `Numeric` implementation into `base`
The `showHex` operation and the `showIntAtBase` operation, which
underlies it, are kept in `GHC.Internal.Numeric`, because `showHex` is
used in a few places in `ghc-internal`; everything else is moved.

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.

hadrian: remove redundant library/rts ways definitions from stock flavours
This patch removes redundant library/rts ways definitions from stock
flavours in hadrian; they can be replaced by applying appropriate
filters on `defaultFlavour`.

ghc-internal: move bits Weak of finalizer interface to base
We move parts of the Weak finalizer interface to `base` only the parts
that the RTS needs to know about are kept in `ghc-internal`.
This lets us then prune our imports somewhat and get rid of some SOURCE imports.
Resolves #26985

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.
Test: codeGen/should_compile/T25650

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.

hadrian: bump index state & bootstrap plans
This patch bumps hadrian index state & bootstrap plans:
- The updated index state allows bootstrapping from 9.14 without cabal
allow-newer hacks
- The updated bootstrap plans all contain shake-0.19.9 containing
important bugfix, allowing a subsequent patch to bump shake bound to
ensure the bugfix is included
- ghc 9.14.1 bootstrap plan is added

T17912: wait for opener thread to block before killing it (#24739)
Instead of a fixed 1000ms delay, poll threadStatus until the opener
thread is in BlockedOnForeignCall, ensuring killThread only fires once
the thread is provably inside the blocking open() syscall. This prevents
the test from accidentally passing on Windows due to scheduling races.

Add a cumulative gc_sync_elapsed_ns counter to GHC.Internal.Stats
This makes it possible to get an accurate view of time spent in sync
phase when using prometheus-style sampling. Previously this was only
available for the most recent GC.
This intentionally leaves GHC.Stats API unchanged since it is marked as
deprecated, and API changes there require CLC approval.

configure: make $LLVMAS default to $CC when $CcLlvmBackend is YES
This patch changes the $LLVMAS detection logic in configure so that
when it's not manually specified by the user, it defaults to $CC if
$CcLlvmBackend is YES. It's a more sensible default than auto-detected
clang from the environment, especially when cross-compiling, $CC as
the cross target's LLVM assembler is more compatible with the use case
than the system-wide clang. Fixes #26769.

exceptions: annotate onException continuation with WhileHandling
Before this patch, an exception thrown in the `onException` handler
would loose track of where the original exception was thrown.
```
import Control.Exception
main :: IO ()
main = failingAction `onException` failingCleanup
where
failingAction = throwIO (ErrorCall "outer failure")
failingCleanup = throwIO (ErrorCall "cleanup failure")
```
would report
```
T28399: Uncaught exception ghc-internal:GHC.Internal.Exception.ErrorCall:
cleanup failure
HasCallStack backtrace:
throwIO, called at T28399.hs:<line>:<column> in <package-id>:Main
```
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
with WhileHandling. The resulting message looks like
```
T28399: Uncaught exception ghc-internal:GHC.Internal.Exception.ErrorCall:
cleanup failure
While handling outer failure
HasCallStack backtrace:
throwIO, called at T28399.hs:7:22 in main:Main
```

Revert "hadrian/build-cabal: Better respect and utilize -j"
This reverts commit eab3dbba79650e6046efca79133b4c0a5257613d.
While it's neat this currently isn't well supported on all platforms.
It's time will come, but for now I'm reverting this to avoid issues for
users on slightly unconvential platforms.
This will be tracked at #26977.

Configure: Fix check for --target support in stage0 CC
The check FP_PROG_CC_LINKER_TARGET used $CC unconditionally to check for
--target support. However this fails for the stage0 config where the C
compiler used is not $CC but $CC_STAGE0.
Since we already pass the compiler under test into the macro I simply
changed it to use that instead.

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.
