Haddock: Add no-compilation flag
This flag makes sure to avoid recompilation of the code when generating documentation by only reading the .hi and .hie files, and throw an error if it can't find them.

Add functions to check for weakly pinned arrays.
This commit adds `isByteArrayWeaklyPinned#` and `isMutableByteArrayWeaklyPinned#` primops.
These check if a bytearray is *weakly* pinned. Which means it can still be explicitly moved
by the user via compaction but won't be moved by the RTS.
This moves us one more stop closer to nailing down #22255.

ghc-toolchain: Don't leave stranded a.outs when testing for -g0
This happened because, when ghc-toolchain tests for -g0, it does so by
compiling an empty program. This compilation creates an a.out.
Since we create a temporary directory, lets place the test program
compilation in it also, so that it gets cleaned up.

Build foreign objects for TH with interpreter's way when loading from iface
Fixes #25211
When linking bytecode for TH from interface core bindings with
`-fprefer-byte-code`, foreign sources are loaded from the interface as
well and compiled to object code in an ad-hoc manner.
The results are then loaded by the interpreter, whose way may differ
from the current build's target way.
This patch ensures that foreign objects are compiled with the
interpreter's way.

rts: fix checkClosure error message
This patch fixes an error message in checkClosure() when the closure
has already been evacuated. The previous logic was meant to print the
evacuated closure's type in the error message, but it was completely
wrong, given info was not really an info table, but a tagged pointer
that points to the closure's new address.

MO_AcquireFence: Less restrictive barrier
GCC and CLang translate the built-in `atomic_thread_fence(memory_order_acquire)`
to `dmb ishld`, which is a bit less restrictive than `dmb ish` (which

testsuite: Add support to capture performance metrics via 'perf'
Performance metrics collected via 'perf' can be more accurate for
run-time performance than GHC's rts, due to the usage of hardware
counters.
We allow performance tests to also record PMU events according to 'perf
list'.

RecordCon lookup: don't allow a TyCon
This commit adds extra logic when looking up a record constructor.
If GHC.Rename.Env.lookupOccRnConstr returns a TyCon (as it may, due to
the logic explained in Note [Pattern to type (P2T) conversion]),
we emit an error saying that the data constructor is not in scope.
This avoids the compiler falling over shortly thereafter, in the call to
'lookupConstructorInfo' inside 'GHC.Rename.Env.lookupRecFieldOcc',
because the record constructor would not have been a ConLike.
Fixes #25056

Use deterministic names for temporary files
When there are multiple threads they can race to create a temporary
file, in some situations the thread will create ghc_1.c and in some it
will create ghc_2.c. This filename ends up in the debug info for object
files after compiling a C file, therefore contributes to object
nondeterminism.
In order to fix this we store a prefix in `TmpFs` which serves to
namespace temporary files. The prefix is populated from the counter in
TmpFs when the TmpFs is forked. Therefore the TmpFs must be forked
outside the thread which consumes it, in a deterministic order, so each
thread always receives a TmpFs with the same prefix.
This assumes that after the initial TmpFs is created, all other TmpFs
are created from forking the original TmpFs. Which should have been try
anyway as otherwise there would be file collisions and non-determinism.
Fixes #25224

Silence x-partial in Haddock.Backends.Xhtml
This is an unfortunate consequence of two mechanisms:
* GHC provides (possibly-empty) lists of names
* The functions that retrieve those names are not equipped to do error
reporting, and thus accept these lists at face value. They will have
to be attached an effect for error reporting in a later refactoring

hadrian: Support loading haddock in ghci
There is one tricky aspect with wired-in packages where the boot package
is built with `-this-unit-id ghc` but the dependency is reported as
`-package-id ghc-9.6...`. This has never been fixed in GHC as the
situation of loading wired-in packages into the multi-repl seems like
quite a niche feature that is always just easier to workaround.

Transform some StgRhsClosure into StgRhsCon after unarisation (#25166)
Before unarisation we may have code like:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
\u []
case (# |_| #) [GHC.Types.(##)] of sat_sAw [Occ=Once1] {
__DEFAULT -> Test.D [GHC.Types.True sat_sAw];
};
After unarisation we get:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
{} \u [] Test.D [GHC.Types.True 2#];
Notice that it's still an Updatable closure for no reason anymore. This
patch transforms appropriate StgRhsClosures into StgRhsCons after
unarisation, allowing these closures to be statically allocated. Now we
get the expected:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
Test.D! [GHC.Types.True 2#];
Fix #25166
To avoid duplicating code, this patch refactors the mk(Top)StgRhs
functions and put them in a GHC.Stg.Make module alongside the new
mk(Top)StgRhsCon_maybe functions.

Don't introduce 'nospec' on the LHS of a RULE
This patch address #25160. The main payload is:
* When desugaring the LHS of a RULE, do not introduce the `nospec` call
for non-canonical evidence. See GHC.Core.InstEnv
Note [Coherence and specialisation: overview]
The `nospec` call usually introdued in `dsHsWrapper`, but we don't want it
on the LHS of a RULE (that's what caused #25160). So now `dsHsWrapper` takes
a flag to say if it's on the LHS of a RULE. See wrinkle (NC1) in
`Note [Desugaring non-canonical evidence]` in GHC.HsToCore.Binds.
But I think this flag will go away again when I have finished with my
(entirely separate) speciaise-on-values patch (#24359).
All this meant I had to re-understand the `nospec` stuff and coherence, and
that in turn made me do some refactoring, and add a lot of new documentation
The big change is that in GHC.Core.InstEnv, I changed
the /type synonym/ `Canonical` into
a /data type/ `CanonicalEvidence`
and documented it a lot better.
That in turn made me realise that CalLStacks were being treated with a
bit of a hack, which I documented in `Note [CallStack and ExecptionContext hack]`.

Add defaulting of equalities
This MR adds one new defaulting strategy to the top-level
defaulting story: see Note [Defaulting equalities] in GHC.Tc.Solver.
This resolves #25029 and #25125, which showed that users were
accidentally relying on a GHC bug, which was fixed by
commit 04f5bb85c8109843b9ac2af2a3e26544d05e02f4
Author: Simon Peyton Jones <simon.peytonjones at gmail.com>
Date: Wed Jun 12 17:44:59 2024 +0100
Fix untouchability test
This MR fixes #24938. The underlying problem was tha the test for
"does this implication bring in scope any equalities" was plain wrong.
This fix gave rise to a number of user complaints; but the improved
defaulting story of this MR largely resolves them.
On the way I did a bit of refactoring, of course
* Completely restructure the extremely messy top-level defaulting
code. The new code is in GHC.Tc.Solver.tryDefaulting, and is much,
much, much esaier to grok.

Do not use an error thunk for an absent dictionary
In worker/wrapper we were using an error thunk for an absent dictionary,
but that works very badly for -XDictsStrict, or even (as #24934 showed)
in some complicated cases involving strictness analysis and unfoldings.
This MR just uses RubbishLit for dictionaries. Simple.
No test case, sadly because our only repro case is rather complicated.

hadrian: Make sure ffi headers are built before using a compiler
When we are using ffi adjustors then we rely on `ffi.h` and
`ffitarget.h` files during code generation when compiling stubs.
Therefore we need to add this dependency to the build system (which this
patch does).
Reproducer, configure with `--enable-libffi-adjustors` and then build
"_build/stage1/libraries/ghc-prim/build/GHC/Types.p_o".
Observe that this fails before this patch and works afterwards.

driver: Ensure we run driverPlugin for staticPlugins (#25217)
driverPlugins are only run when the plugin state changes. This meant they were
never run for static plugins, as their state never changes.
We need to keep track of whether a static plugin has been initialised to ensure
we run static driver plugins at least once. This necessitates an additional field
in the `StaticPlugin` constructor as this state has to be bundled with the plugin
itself, as static plugins have no name/identifier we can use to otherwise reference
them

In particular, I ran into an issue where the cabal invocation `hadrian/ghci` was
using an old index state despite `ci.sh setup` updating and setting the correct
index state. This is because `ci.sh` sets the `CABAL_DIR` to a different place, which
is where the index was downloaded to, but we were using the default cabal directory
outside ci.sh
The solution is to source the correct environment `ci.sh` using `. ci.sh setup`

Parser: be more careful when lexing extended literals (#25258)
Previously we would lex invalid prefixes like "8#Int3" as [8#Int, 3].
A side-effect of this patch is that we now allow negative unsigned
extended literals. They trigger an overflow warning later anyway.

rts: Ensure we dump new Cost Centres added by freshly loaded objects to the eventlog.
To do this, we keep track of the ID of the last cost centre we dumped in DUMPED_CC_ID,
and call dumpCostCentresToEventLog from refreshProfilingCCSs, which will dump all the new
cost centres up to the one we already dumped in DUMPED_CC_ID.
Fixes #24148

Wildcard binders in type declarations (#23501)
Add support for wildcard binders in type declarations:
type Const a b = a -- BEFORE: the `b` had to be named
-- even if unused on the RHS
type Const a _ = a -- AFTER: the compiler accepts
-- a wildcard binder `_`
The new feature is part of GHC Proposal #425 "Invisible binders
in type declarations", and more specifically its amendment #641.
Just like a named binder, a wildcard binder `_` may be:
* plain: _
* kinded: (_ :: k -> Type)
* invisible, plain: @_
* invisible, kinded: @(_ :: k -> Type)
Those new forms of binders are allowed to occur on the LHSs of
data, newtype, type, class, and type/data family declarations:
data D _ = ...
newtype N _ = ...
type T _ = ...
class C _ where ...
type family F _
data family DF _
(Test case: testsuite/tests/typecheck/should_compile/T23501a.hs)
However, we choose to reject them in forall telescopes and
type family result variable binders (the latter being part
of the TypeFamilyDependencies extension):
type family Fd a = _ -- disallowed (WildcardBndrInTyFamResultVar)
fn :: forall _. Int -- disallowed (WildcardBndrInForallTelescope)
(Test case: testsuite/tests/rename/should_fail/T23501_fail.hs)
See the new Notes:
* Note [Type variable binders]
* Note [Wildcard binders in disallowed contexts]
To accommodate the new forms of binders, HsTyVarBndr was changed
as follows (demonstrated without x-fields for clarity)
-- BEFORE (ignoring x-fields and locations)
data HsTyVarBndr flag
= UserTyVar flag Name
| KindedTyVar flag Name HsKind
-- AFTER (ignoring x-fields and locations)
data HsTyVarBndr flag = HsTvb flag HsBndrVar HsBndrKind
data HsBndrVar = HsBndrVar Name | HsBndrWildCard
data HsBndrKind = HsBndrNoKind | HsBndrKind LHsKind
The rest of the patch is downstream from this change.
To avoid a breaking change to the TH AST, we generate fresh
names to replace wildcard binders instead of adding a dedicated
representation for them (as discussed in #641).
And to put a cherry on top of the cake, we now allow wildcards in
kind-polymorphic type variable binders in constructor patterns,
see Note [Type patterns: binders and unifiers] and the tyPatToBndr
function in GHC.Tc.Gen.HsType; example:
fn (MkT @(_ :: forall k. k -> Type) _ _) = ...
(Test case: testsuite/tests/typecheck/should_compile/T23501b.hs)
