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.

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.

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.

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.

Previously we had unnecessary (and incorrect) platform-dependent casts
to turn `OSThreadIds`s into a integer. We now just uniformly cast first
to a `uintptr_t` (which is always safe, regardless of whether
`OSThreadId` is a pointer), and then cast to the desired integral type.
This fixes a warning on musl platforms.

Basic changes:
* Change `catch` function to propagate exceptions using the
WhileHandling mechanism.
* 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.

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.

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.

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.

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.

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.

As noted in #25509, the `-this-package-name` must be passed for each
package to ensure that GHC can response references to the packages'
exposed modules via package-qualified imports. Fix this.
Closes #25509.

This patch makes some minor improvements re nix-in-docker logic in the

- Update `nixos/nix` to the latest version
- Apply $CPUS to `cores`/`max-jobs` to avoid oversubscribing while
allowing a reasonable degree of parallelism
- Remove redundant `--extra-experimental-features nix-command` in

temporary fix of the problem descriped in https://gitlab.haskell
.org/ghc/ghc/-/issues/25495. This commit requires that the LLVM
used contains the code of commit 9dd1d451d9719aa91b3bdd59c0c6679
83e1baf05, i.e., version 8.0 and later. Actually we should not
rely on LLVM, so the only way to solve this problem is to implement
the LoongArch backend.

Currently the ExecPage facility has two users:
* GHCi, for constructing info tables, and
* the adjustor allocation path
Despite neither of these have any spatial locality constraints ExecPage
was using the linker's `mmapAnonForLinker`, which tries hard to ensure
that mappings end up nearby the executable image. This makes adjustor
allocation needlessly subject to fragmentation concerns.
We now instead return less constrained mappings, improving the
robustness of the mechanism.

The combination of ScopedTypeVariables + TypeApplications now no longer
enables the use of type applications in constructor patterns, as per
GHC proposal #448.
This completes the deprecation that begun with GHC 9.8.
We also remove the -Wdeprecated-type-abstractions flag, which was

Previously the structure of `mmapInRegion` concealed a subtle bug
concerning handling of `mmap` returning mappings below the beginning of
the desired region. Specifically, we would reset `p = result + bytes`
and then again reset `p = region->start` before looping around for
another iteration. This resulted in an infinite loop on FreeBSD.

The 'ModuleGraph' abstraction represents the relationship and strucutre
of the modules being compiled. This structure is meant to be constructed
once at the start of compilation, and never changed again.
However, it's exposed interface was confusing and exposed too many
footguns which led to inneficient usages of the ModuleGraph. This commit
improves significantly the exported interface of ModuleGraph, taking
into consideration the recent improvements around reachability queries.
Since the ModuleGraph graphs and related structures (HPT, EPS) are
performance critical in the sense that somewhat simple mistakes can
cause bad leaks and non-linear memory usage, we want to have proper APIs
that guide efficient usage. This is a good step in that direction.

Code analysis shown that such optimization would be possible out of the box if `cachedIdentForId` allowed to do that for Haskell `Id`s which are represented by few JavaScript `Ident`s. It is a usual for strings which are represented at JavaScript as a pair of 2 values: the string content and the offset where to start reading actual string from the full content. Usually offset is 0 but technically we need to allow such complex structures to be treated as "global".
Enabling it there shown that `genToplevelRhs` and `globalOccs` had inaccuracies in their implementations:
1. `globalOccs` operated over JavaScript's `Ident`s but for complex structures it didn't pay attention to the fact that different Idents actually could be pointed to same Id. Now the algo is changed to calculate occurencies for Ids.
2. `genToplevelRhs` didn't assume that different Idents pointed to same Id can have mixed order of occurence. But actually the order is important. Strings are encoded into 2 variables where first is content and second is offset and their order are not interchangeable. It is fixed by regeneration Idents from collected Ids which is fine because all Idents generation is passed through the Cache and they are quasi-stable.

At least some versions of Texlive's `mktexfmt` utility cannot be invoked
concurrently in their initial run since they fail to handle failure of
`mkdir` due to racing. Specifically, we see
```
| Run Xelatex: users_guide.tex => /tmp/extra-dir-9616886274866
| Run Xelatex: Haddock.tex => /tmp/extra-dir-9616886274869
This is XeTeX, Version 3.14159265-2.6-0.999992 (TeX Live 2020) (preloaded format=xelatex)
restricted \write18 enabled.
kpathsea: Running mktexfmt xelatex.fmt
mktexfmt: mktexfmt is using the following fmtutil.cnf files (in precedence order):
mktexfmt: /usr/share/texlive/texmf-dist/web2c/fmtutil.cnf
mktexfmt: mktexfmt is using the following fmtutil.cnf file for writing changes:
mktexfmt: /builds/ghc/ghc/tmp-home/.texlive2020/texmf-config/web2c/fmtutil.cnf
/usr/bin/mktexfmt: mkdir(/builds/ghc/ghc/tmp-home/.texlive2020/texmf-var/web2c/) failed for tree /builds/ghc/ghc/tmp-home/.texlive2020/texmf-var/web2c: File exists at /usr/share/texlive/tlpkg/TeXLive/TLUtils.pm line 937.
I can't find the format file `xelatex.fmt'!
```
That is two `mktexfmt` invocations (for the user's guide and haddock
builds) attempted to create `$HOME/texlive2020/texmf-var/web2c` and
raced. One of the two `mkdir`'s consequently failed, bringing down the
entire build.
We avoid this by ensuring that the first `xelatex` invocation is always
performed serially.
Fixes #25564.

Previously the maximum number of capabilities supported by the RTS was
statically capped at 256. However, this bound is uncomfortably low given
the size of today's machine.
While supporting unbounded, fully-dynamic adjustment would be nice, it
is complex and so instead we do something simpler: Probe the logical
core count at RTS startup and use this as the static bound for the rest
of our execution.
This should avoid users running into the capability limit on large
machines while avoiding wasting memory on a large capabilities array for
most users and keeping complexity at bay.
Addresses #25560.

- Do not print result's kind in type families
because we have full kind in SAKS and we display
invisible arity using @-binders
- Do not suppress significant invisible binders
An invisible binder is considered significant when it meets at least
one of the following two criteria:
- It visibly occurs in the declaration's body
- It is followed by a significant binder,
so it affects positioning
For non-generative type declarations (type synonyms and type families)
there is one additional criterion:
- It is not followed by a visible binder, so it
affects the arity of a type synonym
See Note [Print invisible binders in interface declarations]
for more information about what is "visibly occurs"

Consider a module M importing modules A, B and C.
We can waste a lot of work depending on the order that the modules are
checked for family consistency.
Consider that C imports A and B. When compiling C we must have already
checked A and B for consistency, therefore if C is processed first then
A and B will not need to be checked for consistency again.
If A and B are compared first, then the consistency checks will be
performed against (wasted as we already performed them for C).
At the moment the order which modules are checked is non-deterministic.
Clearly we should engineer that C is checked before B and A, but by what
scheme?
A simple one is to observe that if a module M is in the transitive
closure of X then the size of the consistent family set of M is less
than or equal to size of the consistent family set of X.
Therefore by sorting the imports by the size of the consistent family
set and processing the largest first, you make sure to process modules
in topological order.
In practice we have observed that this strategy has reduced the amount
of consistency checks performed.
One solution to #25554

This is more efficient as:
- All existing filter functions were line-based anyway. They broke up
the input into lines and then joined it back together.
- We already break up the output from system tools into lines when
processing it.
Splitting up the output of system tools once and then filtering and
processing it reduces both code and runtime complexity.

* To improve performance
* To prepare for type-lets
The big changes are all in GHC.Core.Lint:
* Change the main APIs:
* `lintType` returns nothing rather than returning a `LintedType`;
* `lintCoercion` return nothing rather than returning a `LintedCoercion`
Reason: these functions did a lot of allocation to return a substituted
type/coercion that was often discarded, or used only to extract its kind.
Instead we now return nothing, and, when needed, extract the kind and
substitute.
* Applications are treated as a whole, by `lintApp`. By treating
multiple arguments all at once we avoid performing multiple
substitutions, each substituting a single type variable. This can
make an absolutely huge difference.
Overall this led to a pretty massive rewrite of Lint, with many smaller
changes.
Smaller chnages elsewhere
* Rename `GHC.Core.TyCo.Subst.getSubstInScope` to `substInScopeSet` for consistency
* Define and use `GHC.Core.Type.liftedTypeOrConstraintKind`
Performance. This MR someimtes gives gives a very large improvement in
compile time, when Lint is on. here is a selection of changes over 5%
in perf/compiler (with -dcore-lint)
T25196 -97.0%
T14766 -89.7%
T14683 -74.4%
T5631 -60.9%
T20261 -56.7%
T18923 -17.6%
T13035 -15.8%
T6048 -15.8%
CoOpt_Read -14.4%
T9630 -10.9%
T5642 -7.3%
Eliminating the egregious offenders is a big win.
However, in some cases the compiler allocation /increases/. Here ae the
changes over 1%:
T9961 1.5%
T8095 2.8%
T14052 3.9%
T12545 4.5%
T14052Type 5.5%
T5030 8.0%
T5321Fun 8.3%
T3064 12.7%
CoOpt_Singletons 15.6%
T9198 16.0%
LargeRecord 18.1%
I looked at the two biggest increases in compile-time bytes allocated. Interestingly,
they both show substantial *decreases* in actual compile time, due to much smaller GC times.
I'm honestly not sure either why the allocation increases, or why the GC time decreases;
but I'm going to take the win!

IMPORTANT NOTE: These changes don't show up in CI because in CI the
tests in perf/compiler are all run with -dcore-lint switched off. I
gathered this data with some manual runs.

This eta expansion was introduced with the initial commit for Linear
types.
I believe this isn't needed any longer. My guess is it is an artifact
from the initial linear types implementation: data constructors are
linear, but they shouldn't need to be eta expanded to be used as higher
order functions. I suppose in the early days this wasn't true.
For instance, this works now:
data T x = T x
f = \(x :: forall y. y -> T y) -> x True
f T -- ok!
T is linear, but can be passed where an unrestricted higher order
function is expected. I recall there being some magic around to make
this work for data constructors...
Since this works, there's no need to eta_expand the data constructors in
the derived Data instances.

With a recent LLVM, `llc -version` emits the version on the first line
if the vendor is set. It emits the version on the second line
otherwise.
Therefore, we need to check the both lines to detect the version.
GHC now emits a warning if it fails to detect the LLVM version,
so we can notice if the output of `llc -version` changes in the future.
Also, the warning for using LLVM < 10 on s390x is removed, because
we assume LLVM >= 13 now.
This fixes the definition of __GLASGOW_HASKELL_LLVM__ macro.
Fixes #25606

Ticket #25468 showed an assertion failure in CSE because a top-level
Id was being used before it was defined. Reason: Note [Glomming] in
GHC.Core.Opt.OccurAnal.
Solution (used in many places): just put all the top-level bindings in
scope at the beginning of CSE.
Compile-time allocation wobbles up and down a tiny bit; geo mean is
zero. But MultiLayerModulesTH_OneShot and hard_hole_fits increase (on
some architectures only) by a bit oever 2% . I think these are just a
random fluctuations.
Metric Increase:

There were two ad-hoc mechanisms used to determine which modules were in
the interactive scope.
1. Look at everything in the GRE, to see what is imported qualified.
2. Look at the last loaded module in the HPT.
(1) Is very inefficient, GlobalRdrEnvs can be very big.
(2) is incorrect, there is no reason to assume the "last" thing added to
the HPT has any relevance to module loading order.
Happily, the same checks can be implemented directly by looking at the
interactive imports from the interactive context. This mirrors what
happens for normal imports.
Arguably, the error reporting code shouldn't be doing this kind of
processing and it should be an option is set when rendering the error
message. However, this just improves the situation and doesn't block
progress on that front in future.

We found that speculative evaluation can increase the amount of
allocations in some circumstances. This patch adds new flags for
selectively disabling speculative evaluation, allowing us to
test the effect of the optimization.
The new flags are:
-fspec-eval
globally enable speculative evaluation
-fspec-eval-dictfun
enable speculative evaluation for dictionary functions (no effect
if speculative evaluation is globally disabled)
The new flags are on by default for all optimisation levels.

This commit:
- turns the SDoc used in ErrCtxt into a proper error datatype,
ErrCtxtMsg, which contains all the different error contexts that
can be added,
- replaces ErrInfo with [ErrCtxt].
ErrInfo used to contain two SDocs; the first is replaced with [ErrCtxt],
and the second is removed, with the relevant information being put
in the appropriate error message constructors.
Fixes #23436

See:
* https://github.com/haskell/core-libraries-committee/issues/300
Seeks to:
* move existing instances for NonEmpty (except of Eq and Ord) out of GHC.Internal.Base into new GHC.Internal.Data.NonEmpty (to avoid otherwise unavoidable cycles in the module graph);
* move map out of Data.List.NonEmpty (base package) into GHC.Internal.Data.NonEmpty;
* define fmap as map for NonEmpty instance of Functor, avoiding code duplication;
* re-export map from existing GHC.Internal.Data.List.NonEmpty; and
* re-export map from Data.List.NonEmpty (base package);
without breaking anything in the GHC repository.
Various tests *.stdout and *.stderr files are amended also.

Speculative evaluation can cause performance regressions,
therefore we turn it off by default. It can be enabled again
with the -fspec-eval-dictfun flag
