-# Note [The CI Story]
-# ~~~~~~~~~~~~~~~~~~~
-#
-# There are a few different types of pipelines. Among them:
-#
-# 1. marge-bot merges to `master`. Here we perform an exhaustive validation
-# across all of the platforms which we support. In addition, we push
-# performance metric notes upstream, providing a persistent record of the
-# performance characteristics of the compiler.
-#
-# 2. merge requests. Here we perform a slightly less exhaustive battery of
-# testing. Namely we omit some configurations (e.g. the unregisterised job).
-# These use the merge request's base commit for performance metric
-# comparisons.
-#
-# These and other pipelines are defined implicitly by the rules of individual
-# jobs.
-#
-# At the top level, however, we can declare that pipelines (of whatever type)
-# only run when:
-#
-# 1. Processing a merge request (as mentioned above)
-#
-# 2. Processing a tag
-#
-# 3. Pushing to master on the root ghc/ghc repo (as mentioned above)
-#
-# 4. Pushing to a release branch on the root ghc/ghc repo
-#
-# 5. Somebody manually triggers a pipeline from the GitLab UI
-#
-# In particular, note that pipelines don't automatically run just when changes
-# are pushed to a feature branch.

-# HACK
-###
-#
-# Since 58cfcc65 the default for jobs has been "interruptible", this means
-# that when new commits are pushed to a branch which already has a running
-# pipeline then the old pipelines for this branch are cancelled.
-#
-# This includes the master branch, and in particular, new commits merged
-# to the master branch will cancel the nightly job.
-#
-# The semantics of pipeline cancelling are actually a bit more complicated
-# though. The interruptible flag is *per job*, but once a pipeline has run
-# *any* non-interruptible job, then the whole pipeline is considered
-# non-interruptible (ref
-# https://gitlab.com/gitlab-org/gitlab/-/issues/32837) This leads to the
-# hack in this MR where by default all jobs are `interruptible: True`, but
-# for pipelines we definitely want to run, there is a dummy job which
-# happens first, which is `interreuptible: False`. This has the effect of
-# dirtying the whole pipeline and
-#
-# For now, this patch solves the immediate problem of making sure nightly
-# jobs are not cancelled.
-# In the future, we may want to enable this job also for the master
-# branch, making that change might mean we need more CI capacity than
-# currently available.

wasm: ensure post-linker output is synchronous ESM
This patch fixes wasm backend's post-linker output script to ensure
it's synchronous ESM and doesn't use top-level await, which doesn't
work in ServiceWorkers. Fixes #27257.
(cherry picked from commit cccf45da01988801b0c97f7e7ed0160191980226)

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)
Test cases: T11107 T17865

Status check for the HsType~HsExpr refactoring (#25121)
Add a test case to track the status of a refactoring project within GHC
whose goal is to arrive at the following declaration:
type HsType = HsExpr
The rationale for this is to increase code reuse between the term- and
type-level code in the compiler front-end (AST, parser, renamer, type checker).
The status report is saved to testsuite/tests/ghc-api/T25121_status.stdout
and provides useful insights into what needs to happen to make progress on
the ticket.

Record `LinkableUsage` instead of `Linkable` in `LoaderState`
Retaining a ByteCode `Linkable` after it has been loaded retains its
`UnlinkedBCO`, keeping it alive for the remainder of the program.
This starts accumulating a lot of `UnlinkedBCO` and memory over time.
However, the `Linkable` is merely used to later record its usage in
`mkObjectUsage`, which is used for recompilation checking.
However, this is incorrect, as the interface file and bytecode objects
could be in different states, e.g. the interface changes, but the
bytecode library hasn't changed so we don't need to recompile and vice
versa.
By computing a `Fingerprint` for the `ModuleByteCode`, and recording it
in the `LinkableUsage`, we know precisely whether the `ByteCode` object
on disk is outdated.
Thus, parts of this commit just makes sure that we efficiently compute a
`Fingerprint` for `ModuleByteCode` and store it in the on-disk
representation of `ModuleByteCode`.
We change the `LoaderState` to retain `LinkableUsage`, which is smaller
representation of a `Linkable`. This allows us to free the unneeded
fields of `Linkable` after linking them.
We declare the following memory invariants that this commit implements:
* No `LinkablePart` should be retained from `LoaderState`.
* `Linkable`s should be unloaded after they have been loaded.
These invariants are unfortunately tricky to automatically uphold, so we
are simply documenting our assumptions for now.
We introduce the `linkable-space` test which makes sure that after
loading, no `DotGBC` or `UnlinkedBCO` is retained.
-------------------------
Metric Increase:
MultiLayerModulesTH_OneShot
-------------------------
We allocate a bit more, but the peak number of bytes doesn't change.
While a bit unfortunate, accepting the metric increase.
We add multiple new performance measurements where we were able to
observe the desired memory invariants. Further, we add regression tests
to validate that the recompilation checker behaves more correct than
before.

Remove signal-based ticker implementations
Fixes issue #27073
All supported platforms should work with the pthreads + nanosleep based
ticker implementation. This avoids all the problems with using signals.
In practice, all supported platforms were probably using the non-signal
tickers already, which is probably why we do not get lots of reports
about deadlocks and other weirdness: we were definately using functions
that are not async signal safe in the tick handler (such as fflush to
flussh the eventlog).
Only Solaris was explicitly using the timer_create ticker impl, and even
Solaris could probably use the pthreads one (if anyone cared: Solaris is
no longer a Teir 3 supported platform).
Plausibly the only supported platform that this will change will be AIX,
which should now use the pthreads impl.

Streamline expansions using HsExpansion (#25001)
Notes added [Error Context Stack] [Typechecking by expansion: overview]
Notes updated Note [Expanding HsDo with XXExprGhcRn] [tcApp: typechecking applications]
-------------------------
Metric Decrease:
T9020
-------------------------
There are 2 key changes:
1. `HsExpand` datatype mediates between expansions
2. Replace `ErrCtxtM` to a simpler `HsCtxt` that does not depend on a `TidyEnv`
This has some consequences detailed below:
1. `HsExpand` datatype mediates between expansions
* Simplifies the implementations of `tcExpr` to work on `XExpr`
* Removes `VACtxt` (and its associated `VAExpansion` and `VACall`) datatype, it is subsumed by simply a `SrcSpan`.
* Removes the function `addHeadCtxt` as it is now mearly setting a location
* The function `tcValArgs` does its own argument number management
* move `splitHsTypes` out of `tcApp`
* Removes special case of tcBody from `tcLambdaMatches`
* Removes special case of `dsExpr` for `ExpandedThingTc`
* Renames `tcMonoExpr` -> `tcMonoLExpr`, `tcMonoExprNC` -> `tcMonoLExpr`
* Renames `EValArg`, `EValArgQL` fields: `ea_ctxt` -> `ea_loc_span` and `eaql_ctx` -> `eaql_loc_span`
* Remove `PopErrCtxt` from `XXExprGhcRn`
* `fun_orig` in tcInstFun depends on the SrcSpan of the head of the application chain (similar to addArgCtxt)
- it references the application chain head if it is user located, or
uses the error context stack as a fallback if it's a generated
location
* Make a new variant `GeneratedSrcSpan` in `SrcSpan` for HIEAst Nodes
- Expressions wrapped around `GeneratedSrcSpan` are ignored and never added to the error context stack
- In Explicit list expansion `fromListN` is wrapped with a `GeneratedSrcSpan` with `GeneratedSrcSpanDetails` field to store the original srcspan
2. Replace `ErrCtxtM` to a simpler `HsCtxt` that does not depend on a `TidyEnv`
* Merge `HsThingRn` to `HsCtxt`
* Landmark Error messages are now just computed on the fly
* Make HsExpandedRn and HsExpandedTc payload a located HsExpr GhcRn
* `HsCtxt` are tidied and zonked at the end right before printing

Refactor eta-expansion in Prep
The Prep pass does eta-expansion but I found cases where it was
doing bad things. So I refactored and simplified it quite a bit.
In the new design
* There is no distinction between `rhs` and `body`; in particular,
lambdas can now appear anywhere, rather than just as the RHS of
a let-binding.
* This change led to a significant simplification of Prep, and
a more straightforward explanation of eta-expansion. See the new
Note [Eta expansion]
* The consequences is that CoreToStg needs to handle naked lambdas.
This is very easy; but it does need a unique supply, which forces
some simple refactoring. Having a unique supply to hand is probably
a good thing anyway.

Ticket #26831 ended up concluding that the code for
GHC.Core.Opt.Specialise.interestingDict was good, but the
commments were a bit inadequate.

Make inlining a bit more eager for overloaded functions
If we have
f d = ... (class-op d x y) ...
we should be eager to inline `f`, because that may change the
higher order call (class-op d x y) into a call to a statically
known function.
See the discussion on #26831.
Even though this does a bit /more/ inlining, compile times
decrease by an average of 0.4%.

Add more canned GC functions for common register patterns (#27142)
Based on analysis of heap-check sites across the GHC compiler and Cabal,
the following patterns were not covered by existing canned GC functions
but occurred frequently enough to warrant specialisation:
stg_gc_ppppp -- 5 GC pointers
stg_gc_ip -- unboxed word + GC pointer
stg_gc_pi -- GC pointer + unboxed word
stg_gc_ii -- two unboxed words
stg_gc_bpp -- byte (I8) + two GC pointers
Adding these reduces the fraction of heap-check sites falling back to
the generic GC path from ~1.4% to ~0.4% when compiling GHC itself.

Major refactor of free-variable functions
For some time we have had two free-variable mechanims for types:
* The "FV" mechanism, embodied in GHC.Utils.FV, which worked OK, but
was fragile where eta-expansion was concerned.
* The TyCoFolder mechanism, using a one-shot EndoOS accumulator
I finally got tired of this and refactored the whole thing, thereby
addressing #27080. Now we have
* `GHC.Types.Var.FV`, which has a composable free-variable result type,
very much in the spirit of the old `FV`, but much more robust.
(It uses the "one shot trick".)
* GHC.Core.TyCo.FVs now has just one technology for free variables.
All this led to a lot of renaming.
There are couple of error-message changes. The change in T18451
makes an already-poor error message even more mysterious. But
it really needs a separate look.
We also now traverse the AST in a different order leading to a different
but still deterministic order for FVs and test output has been adjusted
accordingly.

packaging: correctly propagate build/host/target to bindist configure script
At the moment the host and target which we will produce a compiler for
is fixed at the initial configure time. Therefore we need to persist
the choice made at this time into the installation bindist as well so we
look for the right tools, with the right prefixes at install time.
In the future, we want to provide a bit more control about what kind of
bindist we produce so the logic about what the host/target will have to
be written by hadrian rather than persisted by the configure script. In
particular with cross compilers we want to either build a normal stage 2
cross bindist or a stage 3 bindist, which creates a bindist which has a
native compiler for the target platform.

Implement modifiers syntax.
The `%m` syntax of linear types is now accepted in more places, to allow
use by future extensions, though so far linear types is still the only
consumer.
This may break existing code where it
* Uses -XLinearTypes.
* Has code of the form `a %m -> b`, where `m` can't be inferred to be
kind Multiplicity.
The code can be fixed either by adding a kind annotation, or by setting
`-XLinearTypes -XNoModifiers`.

hadrian: Don't include the package hash in the haddock directory
Since GHC 9.8 and hash_unit_ids, haddock urls have looked like`ghc-9.10.3/doc/html/libraries/base-4.20.2.0-39f9/**/*.html`
The inclusion of the hash makes it hard for downstream non-boot packages to properly link to these files, as the hash is not
part of a standard cabal substitution.
Since we only build one version of each package, we don't need the hash to disambiguate anything, we can just remove it.

Use upsert for non-deleting map updates
Some compiler functions were using `alter`, despite never removing
any entries: they only update an existing entry or insert a new one.
These functions are converted to using `upsert`:
alter :: (Maybe a -> Maybe a) -> Key -> Map a -> Map a
upsert :: (Maybe a -> a) -> Key -> Map a -> Map a
`upsert` variants are also added to APIs of the various Word64Map
wrapper types.
The precedent for this `upsert` operation is in the containers library:

Allocate static constructors for bytecode
This commit adds support for static constructors when compiling and
linking ByteCode objects.
Top-level StgRhsCon get lowered to ProtoStaticCons rather than to
ProtoBCOs. A ProtoStaticCon gets allocated directly as a data con
application on the heap (using the new primop newConApp#).
Previously, we would allocate a ProtoBCO which, when evaluated, would
PACK and return the constructor.
A few more details are given in Note [Static constructors in Bytecode].
Secondly, this commit also fixes issue #25636 which was caused by
linking *unlifted* constructors in BCO instructions as
- (1) a thunk indexing the array of BCOs in a module
- (2) which evaluated to a BCO which still had to be evaluated to
return the unlifted constructor proper.
The (2) issue has been resolved by allocating the static constructors
directly. The (1) issue can be resolved by ensuring that we allocate all
unlifted top-level constructors eagerly, and leave the knot-tying for
the lifted BCOs and top-level constructors only.
The top-level unlifted constructors are never mutually recursive, so we
can allocate them all in one go as long as we do it in topological
order. Lifted fields of unlifted constructors can still be filled by the
knot-tied lifted variables since in those fields it is fine to keep
those thunks. See Note [Tying the knot in createBCOs] for more details.

test: Validate topoSort logic in createBCOs
This test validates that the topological sorting and ordering of the
unlifted constructors and lifted constructors in `createBCOs` is
correct.
See `Note [Tying the knot in createBCOs]` for why tying the knot for the
created BCOs is slightly difficult and why the topological sorting is
necessary.
This test fails when `let topoSortedObjs = topSortObjs objs` is
substituted by `let topoSortedObjs = zip [0..] objs`, thus witnessing
the toposort logic is correct and necessary.
The test calls the ghci `createBCOs` directly because it is currently
impossible to construct in Source Haskell a situation where a top-level
static unlifted constructor depends on another (we don't have top-level
unlifted constructors except for nullary constructors like `Leaf ::
(UTree :: UnliftedType)`).
This is another test for fix for #25636

Simplify mkTick
This commit simplifies 'GHC.Core.Utils.mkTick', removing the
accumulating parameter 'rest' which was suspiciously treating a bunch of
different ticks as a group, and moving the group as a whole around the
AST, ignoring that the ticks in the group might have different placement
properties.
The most important change is that we revert the logic (added in 85b0aae2)
that allowed ticks to be placed around coercions, which caused serious
issues (e.g. #27121). It was just a mistake, as it doesn't make sense
to put a tick around a coercion.
Also adds Note [Pushing SCCs inwards] which clarifies the logic for
pushing SCCs into lambdas, constructor applications, and dropping SCCs
around non-function variables (in particular the treatment of splittable
ticks).
A few other changes are also implemented:
- simplify 'can_split' predicate (no functional change)
- combine profiling ticks into one when possible

Deal with 'noSpec' in 'coreExprToPmLit'
This commit makes two separate changes relating to
'GHC.HsToCore.Pmc.Solver.Types.coreExprAsPmLit':
1. Commit 7124e4ad mistakenly marked deferred errors as non-canonical,
which led to the introduction of 'nospec' wrappers in the
generated Core. This reverts that accident by declaring deferred
errors as being canonical, avoiding spurious 'nospec' wrapping.
2. Look through magic identity-like Ids such as 'nospec', 'inline' and
'lazy' in 'coreExprAsPmLit', just like Core Prep does.
There might genuinely be incoherent evidence, but that shouldn't
obstruct the pattern match checker. See test T27124a.

Migrate `ghc-pkg` to use `OsPath` and `file-io`
`ghc-pkg` should use UNC paths as much as possible to avoid MAX_PATH
issues on windows.
`file-io` uses UNC Paths by default on windows, ensuring we use the
correct APIs and that we finally are no longer plagued by MAX_PATH
issues in CI and private machines.
On top of it, the higher correctness of `OsPath` is appreciated in this
small codebase. Also, we improve memory usage very slightly, due to the
more efficient memory representation of `OsPath` over `FilePath`
Adds `ghc-pkg` regression test for MAX_PATH on windows
Make sure `ghc-pkg` behaves as expected when long paths (> 255) are
involved on windows.
Let's generate a testcase where we can actually observe that `ghc-pkg`
behaves as epxected.
See the documentation for windows on Maximum Path Length Limitation:
* `https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation`
Adds changelog entry for long path support in ghc-pkg.

Kill off the substitution in Lint
Now that we have invariant (NoTypeShadowing) we no longer
need Lint to carry an ambient substitution. This makes it
simpler and faster. A really worthwhile refactor.
There are some knock-on effects
* Linting join points after worker/wrapper. See
Note [Join points and beta redexes]
* Running a type substitution after the desugarer.
See Note [Substituting type-lets] in
the new module GHC.Core.SubstTypeLets
Implements #27078
Most perf tests don't use Lint so we won't see a perf incresae.
But T1969, which uses -O0 and Lint, gets 1.3% worse because it has
to run the SubstTypeLets pass which is a somewhat expensive no-op
Overall though compile-time allocations are down 0.1%.

Ensure TcM plugins are only initialised once
This commit ensures we keep TcM plugins (typechecker plugins,
defaulting plugins and hole fit plugins) running all the way through
desugaring, instead of stopping them at the end of typechecking.
To do this, the "stop" actions of TcPlugin and DefaultingPlugin are
split into two: one for the "post-typecheck" action, and one for the
final shutdown action (after desugaring).
This allows the plugins to be invoked by the pattern match checker
(during desugaring) without having to be repeatedly re-initialised and
stopped, fixing #26839.
In the process, this commit modifies 'initTc' and 'initTcInteractive',
adding an extra argument that describes whether to start/stop the 'TcM'
plugins.

Make HPC work with bytecode interpreter
Add support to generate .tix files from bytecode objects and the
bytecode interpreter.
Conceptually, we insert HPC ticks into the bytecode similar to how we insert
breakpoints.
HPC and breakpoints do not share the same tick array but we use a separate
tick-array for hpc/breakpoint ticks during bytecode generation.
We teach the bytecode interpreter to handle hpc ticks.
The implementation is quite trivial, simply increment the counter in the
global hpc_ticks array for the respective module.
This hpc_ticks array is generated as part of the `CStub`, so we can rely
on it existing.
A tricky bit is "registering" a bytecode object for HPC instrumentation.
In the compiled case, this is achieved via CStub and initializer/finalizers
`.init` sections which are called when the executable is run.
After the initializers have been invoked, which is before `hs_init_ghc`,
we then call `startup_hpc` in `hs_init_ghc` iff any modules were "registered"
for hpc instrumentation via `hs_hpc_module`.
Since bytecode objects are loaded after starting up GHCi, this workflow
doesn't work for supporting `hpc` and the `hpc` run-time is never
started, even if a module is added for instrumentation.
We fix this issue by employing the same technique as is for `SptEntry`s:
* We introduce a new field to `CompiledByteCode`, called `ByteCodeHpcInfo`
which contains enough information to call `hs_hpc_module`, allowing us to
register the module for `hpc` instrumentation`.
* After registering the module, we unconditionally call `startupHpc`, to make
sure the .tix file is written.
Calling `startupHpc` multiple times is safe.
Calling `hs_hpc_module` multiple times for the same module is also safe.
If we didn't register the hpc module in this way, evaluating a bytecode object
instrumented with `-fhpc` without registering it in the `hpc` run-time will
simply not generate any `.tix` files for this bytecode object.
However, this shouldn't happen if everything is set up correctly.
Closes #27036

* Move NamespaceSpecifier from GHC/Hs/Basic.hs to Language/Haskell/Syntax/ImpExp.hs
and parameterise it by the compiler pass, creating the necessary extension points
* Move NamespaceSpecifier out of XFixitySig into FixitySig
* Move NamespaceSpecifier out of XIEThingAll (IEThingAllExt) into IEThingAll

Make cmm 'import "package" name;' syntax use consistent label types
There is a little-used syntactic form in cmm imports:
import "package" foo;
Which means to import foo from the given package (unit id, specified as
a string). This syntax is somewhat reminiscent of GHC's package import
extension.
This syntax form is not used in the rts cmm code, nor any of the boot
libraries. It may not be used at all. Unclear.
Change the kind of CLabel this syntax generates to be consistent with
the others. The other cmm imports use ForeignLabel with
ForeignLabelInExternalPackage. For some reason this form was using
CmmLabel. Change that to also be ForeignLabel but with
ForeignLabelInPackage. This specifies a specific package, rather
than an unnamed external package.

Change default cmm import statements to be internal
Previously a cmm statement like:
import foo;
meant to expect the symbol from a different shared library than the
current one.
Now it means to expect the symbol from the same shared library as the
current one. We'll add explicit syntax to indicate that it's a foreign
import. Most existing uses are in fact intenal (rts to rts), so few
imports will need to be annotated foreign. Examples would include cmm
code in libraries (other than the rts) that need to access RTS APIs.
In practice, this makes no difference whatsoever at the moment on any
platform other than windows (where building Haskell libs as shared libs
does not fully work yet), since the 'labelDynamic' treats all such
labels as foreign, irrespective of the foreign label source.

Add cmm import syntax 'import DATA foo;' as better name for CLOSURE
The existing syntax is:
import CLOSURE foo;
The new syntax is
import DATA foo;
This means to interpret the symbol foo as refering to data (i.e. a
global constant or variable) rather than to code (a function). The
historical syntax for this uses CLOSURE, which is rather misleading.
Presumably this was done to avoid introducing new reserved words.
Be less squemish about new reserved words and add DATA and use that.
Keep the existing CLOSURE syntax as an alias for compatibility.

Add cmm 'import extern name;' syntax
Since the default for cmm imports is now for symbols within the same
shared object, we need a way to indicate we want a symbol from an
external shared object:
import extern foo; -- for a function
import extern DATA foo; -- for data
This adds a new reserved word 'extern'.
We don't expect to have to use this much. Most cmm imports are
intra-DSO.
This makes no difference currently on ELF and MachO platforms, but does
make a difference to the linking conventions on PE (Windows).
In future it's plausible we could take make distinctions on ELF or
MachO, so it's worth trying to get it right. Windows can be the guinea
pig.

Introduces a test that runs on two capabilities. The main thread running

The TSO from Capability 1 itself checks whether its flags were set and
reports that back.
This validates that the RTS messages for setting TSO flags work, even if

the message passing is necessary for safely setting another TSO's flags.

testsuite: fix flaky foundation Divisible / mulIntMayOflo# tests (#27222)
Since the LCG was widened to 64 bits and the seed randomised per CI run
(commit 2d30f7d3400 "Vendor mini-QuickCheck for testsuite"), two latent
bugs in the foundation test surface stochastically:
* The Divisible property `(x `div` y) * y + (x `mod` y) == x` raises
ArithException(Overflow) when (a, b) = (minBound, -1) for fixed-width
signed Integral types. Split testNumber/testDivisible into Bounded and
unbounded variants and skip just that one pair, gated by
`(minBound :: a) < 0` so unsigned types lose no coverage.
* The `mulIntMayOflo#` test compared raw Int# bit-for-bit, but the primop
is only specified to return 0/non-zero -- the exact non-zero indicator
legitimately differs between backends and inlining choices. Add a
dedicated `testPrimopMayOflo` helper that only compares zero / non-zero.
Also fix the long-standing typo "Dividible" -> "Divisible" in identifiers.

Use __attribute__((dllimport)) for external RTS symbol declarations
This is needed to be hygenic about DLL symbol imports and exports.
The attribute is ignored on platforms other than Windows.
Use of the attribute however means that external data symbols do not
have a compile-time constant address (they are loaded using an
indirection). This means we have to adjust the rtsSyms initial linker
table so that it is a local constant in a function, rather than a global
constant. We now define it within a function that pre-populates the
symbol table with the RTS symbols.

iserv: recover/getQ/putQ should behave same as internal interpreter
The internal and external interpreter should behave the same when
handling `recover`, the exeception recovery method of Q.
In practice, they diverge. In case of failure, the internal interpreter
only restores error message state to before the computation, wheras the
external interperter restores error message state *and* the state of putQ/getQ.
As far as I can tell this is a simple mistake in the implementation.
Note [TH recover with -fexternal-interpreter] describes the correct
behaviour but the implementation doesn't mirror this.
This change restores the correct behaviour by keeping the effects of
putQ in the erroring computation.
This is a breaking change since it modifies the behaviour of programs
that rely on recover ignoring putQ from failling computations when used
with the external interpreter. Although I highly doubt anyone relies on
this behaviour.
This divergence was first introduced in d00c308633fe7d216d31a1087e00e63532d87d6d.
As far as I can tell this was unintentional and tha commit was trying to solve a different bug.

rts: Add dynamic trace flags API
This commit adds an API to the RTS (exposed via Rts.h) that allows users to dynamically change the trace flags.
Prior to this commit, users were able to stop and start the profiling and heap profiling timers (via startProfTimer/stopProfTimer and startHeapProfTimer/stopHeapProfTimer).
This extends that functionality to also cover the core event types.
The getTraceFlag/setTraceFlag functions read and write the values of the trace flag cache, which is allocated by Trace.c, rather than modifying the members of RtsFlags.TraceFlags.
This is done under the assumption that the members of RtsFlags should not be modified after RTS initialisation.
Consequently, if the user modifies the trace flags using setTraceFlag, the object returned by getTraceFlags (from base) will not reflect these changes.
The trace flags are not protected by locks of any sort.
Hence, these functions are not thread-safe.
However, the trace flags are not modified by the RTS after initialisation, only read, so the race conditions introduced by one user modifying them are most likely benign.
This PR also puts the trace flag cache in a single global struct, as opposed to a collection of global variables, and changes the types of the individual flags from uint8_t to bool, as these have the same size on both Clang and GCC and are a better semantic match.
Prior to the change to uint8_t, they had type int, see 42c47cd6.
Even with its deprecation in C23, I don't think there should be any issue depending on stdbool.h.
The TRACE_X macros are redefined to access the global struct, with values cast to const bool to ensure they are read-only.

rts: Fix nonmoving-GC tracing
The current nonmoving-GC tracing functions were written in a different
style from the other tracing functions. They were directly implemented
as, e.g., a traceConcMarkEnd function that called postConcMarkEnd.
The other tracing functions are implemented as, e.g., traceThreadLabel_,
a function that posts the thread label event, and traceThreadLabel, a
macro that checks whether TRACE_scheduler is set. This commit fixes that
implementation, and ensures that the nonmoving-GC tracing functions only
emit events if nonmoving-GC tracing is enabled.

Add a rts posix FdWakup utility module
This will be used to implement wakeupIOManager for in-RTS I/O managers.
It provides a notification/wakeup mechanism using FDs, suitable for
situations when a thread is blocked on a set of fds anyway. It uses the
classic self-pipe trick, or equivalently eventfd on supported platforms.
This will initially be used to implement prompt interrupt or shutdown of
the posix ticker thread.

Add prompt shutdown to the pthread ticker implementation.
The Linux timerfd ticker monitors a pipe which is used by exitTicker to
ensure a prompt wakeup and shutdown. The pthread ticker lacked this and
so would only exit at the next ticker wakeup (10ms by default).
This patch adds the same mechanism to the pthread ticker.
This changes the pthread ticker from waiting by using nanosleep() to
waiting using either ppoll() or select(), so that it can wait on both
a time and a file descriptor. On Linux at least, a test program to
compare the timing jitter of these APIs shows that using nanpsleep,
ppoll or select makes no statistical difference to the maximum or
average jitter.
This is a step towards unifying the posix ticker implementations, so
that we can have just one portable one (albeit with some limited cpp).
It is also a step towards using the ticker as part of a more general
implementation of wakeUpRts, since this will require a method to wake
the rts from a signal handler context (ctl-c handler).

Remove the timerfd-based ticker implementation
There does not appear to be any remaining advantage on Linux to using
the timerfd ticker implementation over the portable one (using ppoll on
Linux for precise timing).
The eventfd implementation was originally added at a time when Linux was
still using a signal based implementation. So it made sense at the time.

Generalize so_inline to specify which bindings should be preserved
This commit generalizes the so_inline option of the simple optimizer
so we can indicate with a predicate the specific bindings that should
be kept.
This feature is important for the LiquidHaskell plugin, which relies on the
simple optimizer to make core programs easier to read, but needs to preserve
bindings that are relevant for verification.

Add minimal dlltool support to ghc-toolchain
The dlltool is a tool that can create dll import libraries from .def
files. These .def files list the exported symbols of dlls. Its somewhat
like gnu linker scripts, but more limited.
We will need dlltool to build the rts and ghc-internal libraries as DLLs
on Windows. The rts and ghc-internal libraries have a recursive
dependency on each other. Import libraries can be used to resolve
recursive dependencies between dlls. We will use an import library for
the rts when linking the ghc-internal library.

Update and generate libHSghc-internal.def from .def.in file
The only symbol that the rts imports from the ghc-internal package now
is init_ghc_hs_iface. So the rts only needs an import lib that defines
that one symbol.
Also, remove the libHSghc-prim.def because it is redundant. The rts no
longer imports anything from ghc-prim.
Keep libHSffi.def for now. We may yet need it once it is clear how
libffi is going to be built/used for ghc.

Add rule to build libHSghc-internal.dll.a and link into the rts
On windows only, with dynamic linking.
This is needed because on windows, all symbols in dlls must be resolved.
No dangling symbols allowed. References to external symbols must be
explicit. We resolve this with an import library. We create an import
library for ghc-internal, a .dll.a file. This is a static archive
containing .o files that define the symbols we need, and crucially have
".idata" sections that specifies the symbols the dll imports and from
where.
Note that we do not install this libHSghc-internal.dll.a, and it does
not need to list all the symbols exported by that package. We create a
special purpose import lib and only use it when linking the rts dll, so
it only has to list the symbols that the rts uses from ghc-internal
(which is exactly one symbol: init_ghc_hs_iface).

Introduce a cache of home module name providers
This contribution introduces to the module graph a cache that maps home
module names to sets of units providing them and changes the finder to
use that cache. This is a performance optimization, especially for
multi-home-unit builds.
The particular changes are as follows:
* In `GHC.Unit.Module.Graph`, `ModuleGraph` is extended with a new
field `mg_home_module_name_providers_map`, exposed as
`mgHomeModuleNameProvidersMap`. This is a cache that assigns to each
home module name the set of IDs of home units that define it.
Operations that construct module graphs are updated such that this
cache stays synchronized.
* In `GHC.Unit.Finder`, `findImportedModule` is changed to pull
`mgHomeModuleNameProvidersMap` from `hsc_mod_graph` and pass it to
`findImportedModuleNoHsc`, which now does not search home units in
arbitrary order but prioritizes those units that the cache mentions
as potential providers of the requested module.
In addition, this contribution adds variants of the two multi-component
compiler performance tests that use 100 units instead of 20, because
with just 20 units the benefits from caching of home module name
providers are still negligible.
The following table shows the total time needed for running both
multi-component tests before and after this contribution and with
different numbers of units:
| # of units | Before | After |
|-----------:|-------:|------:|
| 20 | 0:12 | 0:12 |
| 100 | 0:47 | 0:42 |
| 200 | 3:05 | 2:08 |
Note that there seems to be a general overhead of 12 seconds that is not
attributable to the actual tests, so that the real running times should
be 12 seconds smaller than shown above.
Resolves #27055.

AArch64: use ASR not LSR for MO_U_Shr at W8/W16
The unsigned right shift (MO_U_Shr) for sub-word widths (W8, W16)
with a variable shift amount was emitting ASR (arithmetic/signed shift
right) after zero-extending with UXTB/UXTH. This should be LSR
(logical/unsigned shift right). After zero-extension the upper bits
happen to be 0 so ASR produces the same result, but it is semantically
wrong and would break if the zero-extension were ever optimized away.
Includes assembly output test (grep for lsr) and runtime test
verifying unsigned right shift of Word8 and Word16 values.

Hadrian: remove legacy rts .so symlinks
For compatibility with the old makefile based build system, hadrian had
rules to generate symlinks from unversioned to versioned names for the
rts .so/.dynlib file, like libHSrts-ghcx.y.so -> libHSrts-1.0.3-ghcx.y.so
We no longer need these symlinks since the makefile build system has
been retired some time ago. The need for these symlinks is awkward on
windows where we cannot (in practice) create symlinks. So rather than
make them conditional (non-windows), just remove them entirely.

Fix regression T27202: `:load` and `:add` work in GHCi
To fix the regression there are conceptually two major things that we
fix:
* We don't remove the `importDirs` from `interactive-session`
* When `:add`ing a module, we don't try to find them via PackageImports
* The PackageImport is wrong as we can't know the package-name at
this stage in ghc/UI.hs
What does it mean to not remove the `importDirs` from
`interactive-session`?
It means that, given some initial `DynFlags`, we will use those
`importDirs` in `interactive-session`.
The initial `DynFlags`, however, depend on how you initialise the GHC
session.
For a simple session, initialised by
ghc -isrc -this-unit-id main
It is simple, just use the `DynFlags` given on the cli.
Thus, `main` and `interactive-session` will have the same `DynFlags`,
except for the `homeUnitId` and `interactive-session` depends on `main`
by construction of the GHCi session.
What about a multiple home unit session, though?
ghc -unit @unit1 -unit @unit2
What are the `DynFlags` in this cli invocation? It shouldn't be either
`@unti1` nor `@unit2`, as the order shouldn't matter or any other
implicit condition.
For consistency, we decide that the initial `DynFlags` are the top
`DynFlags` on the cli, ignoring `-unit` flags.
Thus, in this example, there are no `importsDirs` regardless of what we
might find in `@unit1` and `@unit2`.
But in this invocation:
ghc -isrc -unit @unit1 -unit @unit2
The `interactive-session` will have the `importsDirs` `src`.
Note, `-isrc` will be inherited in `@unit1` and `@unit2`, so you need to
explicitly use `-i` to clear the `importsDirs`, in order to avoid
accidentally adding `src` as an import directory to all other home
units.
This fix has been made possible by the improvements introduced in
!15888, which avoids ambiguity when a home unit shares the `importsDirs`
with the `interactive-session`, on top of being much faster for multiple
home units.
Adds regression tests for T27202 for `:load`ing and `:add`ing modules
that are located in import directories.

Use home unit package db stacks in GHCi prompt and session unit
In order to import modules from home unit dependencies (e.g., `Data.Map`),
the ghci prompt unit needs to populate its `UnitState`.
This is tricky to handle correctly, which `PackageDBFlag`s should we use
to populate the `UnitState`?
We decide, the most intuitive solution for users is to depend on all
`PackageDBFlag`s, so that any dependency can be imported in GHCi.
This assumes consistency in the `PackageDBFlag`s, so no two home units
specify `PackageDBFlag`s that are inconsistent with each other.
We could simply concat all the `PackageDBFlag`s of the existing home
units, but later `PackageDBFlag`s shadow earlier ones, leading to the
last processed home units' `PackageDBFlag`s to shadow the earlier ones.
This is hard to fix, we need to give users the capability to provide ghc
options for the ghci prompt home unit.
However, as this is considerably more work, we decided on an
approximation that should work out most of the time.
Package Db stacks in cabal and stack follow a certain structure:
-no-user-package-db > -package-db $cabal-store > -package-db $local-db
The first two arguments are always the same, namely the
`-no-user-package-db` and `-package-db`.
We compute the longest common prefix over all home units, and use that
as the start of the package db stack. Then, over the rest of the
`PackageDBFlag`s, we simply take the union and append them to our
initial stack.
We assume, that the rest of package dbs only defines very few, "local"
units that are usually not shadowing each other.
This allows us to get a relatively consistent package database stack for
the ghci prompt home unit.
Similar reasoning applies to the session unit in order to add modules to
the session and have dependencies available in the module.
We do something similar for `-package` flags, to make sure only the
correct units are actually visible in the ghci session.
This time, we simply take the union of all `PackageFlag`s, allowing us
to import modules from the home unit dependencies.
In the future, it would be beneficial to allow the user to provide the
exact ghc options to control the visibilities. For now, this will have
to do.

Major refactor of the Simplifier
The main payload of this patch is to refactor the Simplifer to avoid
repeated simplification when using Plan (AFTER) for rule rewrites.
The need for this was shown up by #26989.
See Note [Avoid repeated simplification] in GHC.Core.Opt.Simplify.Iteration.
Related refactoring:
* Refactor the two fields `sc_dup` and `sc_env` in `ApplyToVal` into one, `sc_env`.
Reason: the envt is irrelevant in the "simplified" case, so the data type describes
the possiblitiies much more accurately now.
* Some refactoring in `knownCon` to split off `wrapDataConFloats`.
* Refactor `lookupRule` and its auxiliary functions to return `RuleMatch`,
a new data type. See Note [data RuleMatch] in GHC.Core. Ditto for BuiltinRule.
This RuleMatch returns fragments of the target in rm_args and rm_floats,
leaving `rm_rhs` to be the stuff from the RULE itself.
Doing this has routine consequences in GHC.Core.Opt.ConstantFold. Many changes
there but all routine.
* When doing occurrence analysis on RULEs, make the occ-info on the rule
binders relate just to the RHS, not the LHS. See (OUR1) in
Note Note [OccInfo in unfoldings and rules]
This means that Lint must not complain about the fact that the patterns
in the RULE mentions binders that are marked dead.
See Note [Dead occurrences] in GHC.Core.Lint.
I changed the Core pretty-printer so that it didn't suppress dead binders,
else I can't see those binders in RULEs. That led to quite a lot of testsuite wibbles.
* Refactor FloatBinds, so that it is used both by
`exprIsConApp_mabye` and by `lookupRule`
* Move the definition of FloatBinds out of GHc.Core.Make, into GHC.Core.
* Add FloatTick as an extra constructor.
* Refactor `lookupRule` to use `FloatBinds` instead of `BindWrapper`.
This refactor just shares more code.
(Rename GHC.Core.Opt.FloatOut.FloatBinds to FloatLets, to avoid gratuitious
name clash with GHC.Core.FloatBinds.)
Corecion optimisation
* In simpleOpt, when composing coercions, call new function `optTransCo`.
This is much lighter weight than full blown coercion optimisation.
* Make `GHC.Core.Opt.Arity.pushCoValArg` and `pushCoTyArg` return the
coercionLKind of the coercion. This saves recomputing that coercionLKind
at the key call sites in GHC.Core.Opt.Simplify.Iteration.pushCast.
* Rename `addCoerce` in GHC.Core.Simplify.Iteration to become `pushCast`.
* In the `ApplyToVal` case of `pushCast` we had a very unsavoury call to `simplArg`.
I eliminated it by adding a field `sc_cast` to `ApplyToVal` that records any
pending casts. Much nicer now. See Note [The sc_cast field of ApplyToVal].
* Don't optimise coercions if the type-substitution is empty.
See Note [Optimising coercions] in GHC.Core.Opt.Simplify.Iteration.

However, strangely there seems to be a 5.0% increase in CoOpt_Read in
the x86_64-linux-fedora43-validate+debug_info+ubsan job, although
there generally a /decrease/ in this test in other builds. The baseline
value looks strange. Anyway I'll just accept it.

Speed up 'closure' computation in `ghc-pkg`
Cache the set of already seen `UnitId`s and use `Set` operations to
speed up 'closure' computation.
Further simplify the implementation of 'closure' to account for the
actual usage.
As a consequence, we rename 'closure' to 'brokenPackages' to reflect its
purpose better after the simplification.

TcMPluginHandling: be more lenient when no plugins
This change ensures that, if a function such as 'typecheckModule' was
invoked with 'NoTcMPlugins', GHC doesn't spuriously complain about TcM
plugins having already been stopped, as there were none to start with.

Fix ambiguous syntax of BangPatterns in users guide
Update documentation for the BangPatterns extension to specify
how surrounding whitespace affects interpretation of `!`.
* Only when there is whitespace before `!` and no whitespace after,
it is recognized as a BangPattern.
* Other cases `⟨varid⟩!⟨varid⟩`, `⟨varid⟩ ! ⟨varid⟩`, `⟨varid⟩! ⟨varid⟩`
are treated as infix operators.

Update to semaphore-compat 2.0.0 using v2 of the protocol
On Linux and other POSIX platforms, GHC's -jsem jobserver client now
speaks v2 of the semaphore-compat protocol, which uses Unix domain
sockets in place of POSIX named semaphores. This avoids the libc-ABI
issues that affected the old implementation. Windows is unaffected
and continues to use the v1 protocol (Win32 named semaphores); its
reported protocol version remains v1.
When GHC receives a -jsem name whose protocol version it does not
support, it emits a -Wsemaphore-version-mismatch warning and falls
back to -j<N> rather than crashing. ghc --info exposes the supported
version in a new "Semaphore version" entry so cabal-install can detect
a mismatch before invoking GHC.
Users on a cabal-install that predates the v2 update will continue to
build successfully on Linux/POSIX, but will lose the cross-process
-jsem coordination and fall back to -j<N> per GHC invocation. Users
must upgrade to a cabal-install that supports protocol v2 to recover
full parallelism.
Also fix a leak in cleanupSem (#27253): cleanupSem used to snapshot
heldTokens and release them before killing the loop, while the loop's
in-flight acquire/release children could still be mutating it.
Cleanup now runs inside the loop's own exit handler, after draining
the active child via a new activeChild TVar, so the snapshot has no
concurrent mutator.

Revert prog003 acceptance
We thought the commit 286f1adff3e78d775ff325caff71d0cee25d710b fixed the
test, but due to changes to ghci, modules loaded during the GHCi
session, the test was actually no longer testing what it set out to do,
"fixing" the broken test.
As modules are added to the `interactive-session` home unit, the object code needs
to be compiled with `-this-unit-id interactive-session`, otherwise the
object code won't be used.
Once this has been fixed in the test, the test fails as expected again.
