Assert that ctEvCoercion is called on an equality
Calling 'ctEvCoercion' on non-equality constraints is always incorrect.
We add an assertion to this function to detect such cases; for example
a type-checking plugin might erroneously do this.

Remove unused USE_REPORT_PRELUDE code paths from the tree
This patch removes unused `USE_REPORT_PRELUDE` code paths from the
tree. They have been present since the first git revision
4fb94ae5e5d632748fa2e6c35e259eccc5a1a3f4, and might have been useful
for debugging purposes many years ago, but these code paths are never
actually built. Removing these ease maintenance of relevant modules in
the future, and also allows us to get rid of `CPP` extension in those
modules as a nice byproduct.

Refactored BooleanFormula to be in line with TTG (#21592)
There are two parts to this commit.
* We moved the definition of BooleanFormula over to L.H.S.BooleanFormula
* We parameterized the BooleanFormula over the pass
The GHC specific details of BooleanFormula remain in Ghc.Data.BooleanFormula.
Because its parameterized over the pass its no longer a functor or
traversable, but we defined bfMap and bfTraverse for the cases where we
needed fmap and traverse originally. Most other changes are just churn.

Re CLC #293 - Don't specify Data.List.NonEmpty in terms of partial
See https://github.com/haskell/core-libraries-committee/issues/293
`List.init` had already been driven out of `tails1` by 21fc180bec93d964a7f4ffdf2429ef6f74b49ab6 but this specification also avoided partial `fromList`, so I preferred it.
The `changelog.md` for `base` is updated, with an entry added under `base-4.22.0.0`.

hadrian: Enforce the usage of GHC >=9.8.1 for ghci-multi

Handle the special ghc-prim:GHC.Prim module in the compiler
Before this patch, some custom hacks were necessary in ghc-prim's
Setup.hs to register the GHC.Prim (virtual) module and in Hadrian to
generate haddocks properly.
In this patch we special-case this module in the compiler itself instead
(which it already is, see ghcPrimIface in GHC.Iface.Load). From
Cabal/Hadrian's perspective GHC.Prim is now just a normal autogenerated
module.
This simplification is worthwhile on its own. It was found while looking
into the work needed for #24453 which aims to merge ghc-prim,
ghc-bignum, and ghc-internal. It's also one step closer to remove
ghc-prim's custom setup.

configure: Check version number validity
Here we verify the previously informal invariant that stable release
version numbers must have three components, preventing costly failed
releases.
Specifically, the check fails in the following scenarios:
* `version=9.13` while `RELEASE=YES` since this would imply a
release made from an unstable branch
* `version=9.13.0` since unstable versions should only have two
components
* `version=9.12` since this has the wrong number of version components
for a stable branch
Fixes #25390.

test driver: fix file collection for regex linters
When a testsuite linter is executed with the `tracked` strategy, the
driver runs `git ls-tree` to collect eligible files.
This appears to have ceased producing any paths – `ls-tree` restricts
its results to the current working directory, which is
`testsuite/tests/linters` in this case.
As a quick fix, this patch changes the working directory to match
expectations.

hadrian: fix bindist makefile for wasm32-wasi target
This patch fixes one incoherent place between bindist makefile and
hadrian logic: I forgot to include wasi/wasm32 in
OsSupportsGHCi/ArchSupportsGHCi as well. And this results in incorrect
settings file generated after installing the bindist, and "Use
interpreter"/"Have interpreter" fields incorrectly have "NO" values
where they should be "YES" like --info output of in-tree version.

boot: Do not attempt to update config.sub
While Apple ARM hardware was new we found that the autoconf scripts
included in some boot packages were too old. As a mitigation for this,
we introduced logic in the `boot` script to update the `config.sub`
with that from the GHC tree. However, this causes submodules which
have `config.sub` committted to appear to be dirty. This is a
considerable headache.
Now since `config.sub` with full platform support is more common we can
remove `boot`'s `config.sub` logic.
Fixes #19574.

misc: improve clangd compile_flags.txt flags
This patch improves the compile_flags.txt config used to power clangd
for the rts C codebase. The flags in the file are sampled & deduped
from a real stage1 build with clang-19 and vastly improves the IDE
accuracy when hacking the rts.
For maximum code coverage under the default settings,
compile_flags.txt defaults to threaded+profiled+dynamic+debug way.
This does not mean profdyn needs to be actually built in _build/stage1
for IDE to work. To activate IDE for other RTS ways, simply remove one
of the -D flags at the end of compile_flags.txt and restart clangd.

Considering trees containing untracked files as dirty is a bridge too

in the dirtiness check.

Previously we had unnecessary (and incorrect) platform-dependent casts

* Introduce `catchNoPropagate`, which does the same as before, but
passes an exception which can be rethrown.
* Introduce `rethrowIO` combinator, which rethrows an exception with a
context and doesn't add a new backtrace.
* Introduce `tryWithContext` for a variant of `try` which can rethrow
the exception with it's original context.
* onException is modified to rethrow the original error rather than
creating a new callstack.
* Functions which rethrow in GHC.Internal.IO.Handle.FD,
GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and
GHC.Internal.System.IO.Error are modified to not add a new callstack.

exceptions: Improve the message layout as per #285
This commit fixes the layout of the additional information included when
displaying an exception, namely the type of the exception.
It also fixes the default handler's heading message to work well
together with the improved display message of SomeException.

Display type and callstack of exception on handler
This commit changes the Exception instance of SomeException to *simply*
display the underlying exception in `displayException`. The augmented
exception message that included the type and backtrace of the exception
are now only printed on a call to `displayExceptionWithInfo`.
At a surface level, existing programs should behave the same since the
`uncaughtExceptionHandler`, which is responsible for printing out uncaught
exceptions to the user, will use `displayExceptionWithInfo` by default.
However, unlike the instance's `displayException` method, the
`uncaughtExceptionHandler` can be overriden with
`setUncaughtExceptionHandler`. This makes the extra information opt-in
without fixing it the instance, which can be valuable if your program
wants to display uncaught exceptions to users in a user-facing way
(ie without backtraces).
This is what was originally agreed for CLC#231 or CLC#261 with regard to
the type of the exception information.
The call stack also becoming part of the default handler rather than the
Exception instance is an ammendment to CLC#164.
Discussion of the ammendment is part of CLC#285.

Remove redundant CallStack from exceptions
Before the exception backtraces proposal was implemented, ErrorCall

ExceptionContext is now accumulated automatically.
The original ErrorCall mechanism is now redundant and we get a duplicate

re-defining displayExceptionContext.

Fix exception backtraces from GHCi
When running the program with `runhaskell`/`runghc` the backtrace should
match the backtrace one would get by compiling and running the program.
But currently, an exception thrown in a program interpreted with
`runhaskell` will:
* Not include the original exception backtrace at all
* Include the backtrace from the internal GHCi/ghc rethrowing of the
original exception
This commit fixes this divergence by not annotating the ghc(i) backtrace
(with NoBacktrace) and making sure that the backtrace of the original
exception is serialized across the boundary and rethrown with the
appropriate context.
Fixes #25116

x86 NCG: fix regUsageOfInstr for VMOVU & friends
This commit fixes the implementation of 'regUsageOfInstr' for vector
operations that take an 'Operand' as the destination, by ensuring that
when the destination is an address then the address should be *READ*,
and not *WRITTEN*.
Getting this wrong is a disaster, as it means the register allocator
has incorrect information, which can lead to it discard stores to
registers, segfaults ensuing.

Improve reachability queries on ModuleGraph
Introduces `ReachabilityIndex`, an index constructed from a
`GHC.Data.Graph.Directed` `Graph` that supports fast reachability
queries (in $O(1)$). This abstract data structure is exposed from
`GHC.Data.Graph.Directed.Reachability`.
This index is constructed from the module graph nodes and cached in
`ModuleGraph`, enabling efficient reachability queries on the module
graph. Previously, we'd construct a Map of Set of ModuleGraph nodes
which used a lot of memory (`O(n^2)` in the number of nodes) and cache
that in the `ModuleGraph`. By using the reachability index we get rid of
this space leak in the module graph -- even though the index is still
quadratic in the number of modules, it is much, much more space
efficient due to its representation using an IntMap of IntSet as opposed
to the transitive closure we previously cached.
In a memory profile of MultiLayerModules with 100x100 modules, memory
usage improved from 6GB residency to 2.8GB, out of which roughly 1.8GB
are caused by a second space leak related to ModuleGraph. On the same
program, it brings compile time from 7.5s to 5.5s.
Note how we simplify `checkHomeUnitsClosed` in terms of
`isReachableMany` and by avoiding constructing a second graph with the
full transitive closure -- it suffices to answer the reachability query
on the full graph without collapsing the transitive closure completely
into nodes.
Unfortunately, solving this leak means we have to do a little bit more
work since we can no longer cache the result of turning vertex indices
into nodes. This results in a slight regression in MultiLayerModulesTH_Make,
but results in large performance and memory wins when compiling large
amounts of modules.

compiler: remove unused GHC.Linker.Loader.loadExpr
This patch removes the unused `GHC.Linker.Loader.loadExpr` function.
It was moved from `GHC.Runtime.Linker.linkExpr` in `ghc-9.0` to
`GHC.Linker.Loader.loadExpr` in `ghc-9.2`, and remain completely
unused and untested ever since. There's also no third party user of
this function to my best knowledge, so let's remove this. Anyone who
wants to write their own GHC API function to load bytecode can consult
the source code in older release branches.
