Fix BCO creation setting caps when -j > -N
* Remove calls to 'setNumCapabilities' in 'createBCOs'
These calls exist to ensure that 'createBCOs' can benefit from
parallelism. But this is not the right place to call
`setNumCapabilities`. Furthermore the logic differs from that in the
driver causing the capability count to be raised and lowered at each TH
call if -j > -N.
* Remove 'BCOOpts'
No longer needed as it was only used to thread the job count down to `createBCOs`
Resolves #23049

configure: Fix FIND_CXX_STD_LIB test on Darwin
Annoyingly, Darwin's <cstddef> includes <version> and APFS is
case-insensitive. Consequently, it will end up #including the
`VERSION` file generated by the `configure` script on the second
and subsequent runs of the `configure` script.
See #23116.

ghci: only keep the GlobalRdrEnv in ModInfo
The datatype GHC.UI.Info.ModInfo used to store a ModuleInfo,
which includes a TypeEnv. This can easily cause space leaks as we
have no way of forcing everything in a type environment.
In GHC, we only use the GlobalRdrEnv, which we can force completely.
So we only store that instead of a fully-fledged ModuleInfo.

Add structured error messages for GHC.Tc.Utils.Backpack
Tracking ticket: #20119
MR: !10127
This converts uses of `mkTcRnUnknownMessage` to newly added constructors
of `TcRnMessage`.
One occurrence, when handing a nested error from the interface loading
machinery, was omitted. It will be handled by a subsequent changeset
that addresses interface errors.

Rename () into Unit, (,,...,,) into Tuple<n> (#21294)
This patch implements a part of GHC Proposal #475.
The key change is in GHC.Tuple.Prim:
- data () = ()
- data (a,b) = (a,b)
- data (a,b,c) = (a,b,c)
...
+ data Unit = ()
+ data Tuple2 a b = (a,b)
+ data Tuple3 a b c = (a,b,c)
...
And the rest of the patch makes sure that Unit and Tuple<n>
are pretty-printed as () and (,,...,,) in various contexts.
Updates the haddock submodule.

This patch adds a conservative but always correct
CmmCgInfos when the JavaScript backend is used.

Be more careful about quantification
This MR is driven by #23051. It does several things:
* It is guided by the generalisation plan described in #20686.
But it is still far from a complete implementation of that plan.
* Add Note [Inferred type with escaping kind] to GHC.Tc.Gen.Bind.
This explains that we don't (yet, pending #20686) directly
prevent generalising over escaping kinds.
* In `GHC.Tc.Utils.TcMType.defaultTyVar` we default RuntimeRep
and Multiplicity variables, beause we don't want to quantify over
them. We want to do the same for a Concrete tyvar, but there is
nothing sensible to default it to (unless it has kind RuntimeRep,
in which case it'll be caught by an earlier case). So we promote
instead.
* Pure refactoring in GHC.Tc.Solver:
* Rename decideMonoTyVars to decidePromotedTyVars, since that's
what it does.
* Move the actual promotion of the tyvars-to-promote from
`defaultTyVarsAndSimplify` to `decidePromotedTyVars`. This is a
no-op; just tidies up the code. E.g then we don't need to
return the promoted tyvars from `decidePromotedTyVars`.
* A little refactoring in `defaultTyVarsAndSimplify`, but no
change in behaviour.
* When making a TauTv unification variable into a ConcreteTv
(in GHC.Tc.Utils.Concrete.makeTypeConcrete), preserve the occ-name
of the type variable. This just improves error messages.
* Kill off dead code: GHC.Tc.Utils.TcMType.newConcreteHole

Refactor the constraint solver pipeline
The big change is to put the entire type-equality solver into
GHC.Tc.Solver.Equality, rather than scattering it over Canonical
and Interact. Other changes
* EqCt becomes its own data type, a bit like QCInst. This is
great because EqualCtList is then just [EqCt]
* New module GHC.Tc.Solver.Dict has come of the class-contraint
solver. In due course it will be all. One step at a time.
This MR is intended to have zero change in behaviour: it is a
pure refactor. It opens the way to subsequent tidying up, we
believe.

Allow WARNING pragmas to be controlled with custom categories
Closes #17209. This implements GHC Proposal 541, allowing a WARNING
pragma to be annotated with a category like so:
{-# WARNING in "x-partial" head "This function is undefined on empty lists." #-}
The user can then enable, disable and set the severity of such warnings
using command-line flags `-Wx-partial`, `-Werror=x-partial` and so on. There
is a new warning group `-Wextended-warnings` containing all these warnings.
Warnings without a category are treated as if the category was `deprecations`,
and are (still) controlled by the flags `-Wdeprecations`
and `-Wwarnings-deprecations`.
Updates Haddock submodule.

of unaligned stores as a temporary mitigation.

Modify ThreadId documentation and comments
For a long time, `GHC.Conc.Sync` has said
```haskell
-- ToDo: data ThreadId = ThreadId (Weak ThreadId#)
-- But since ThreadId# is unlifted, the Weak type must use open
-- type variables.
```
We are now actually capable of using `Weak# ThreadId#`, but the
world has moved on. To support the `Show` and `Ord` instances, we'd
need to store the thread ID number in the `ThreadId`. And it seems
very difficult to continue to support `threadStatus` in that regime,
since it needs to be able to explain how threads died. In addition,
garbage collection of weak references can be quite expensive, and it
would be hard to evaluate the cost over he whole ecosystem. As discussed
in
[this CLC issue](https://github.com/haskell/core-libraries-committee/issues/125),
it doesn't seem very likely that we'll actually switch to weak
references here.

rts: Don't rely on EXTERN_INLINE for slop-zeroing logic
Previously we relied on calling EXTERN_INLINE functions defined in
ClosureMacros.h from Cmm to zero slop. However, as far as I can tell,
this is no longer safe to do in C99 as EXTERN_INLINE definitions may be emitted
in each compilation unit.
Fix this by explicitly declaring a new set of non-inline functions in
ZeroSlop.c which can be called from Cmm and marking the ClosureMacros.h
definitions as INLINE_HEADER.
In the future we should try to eliminate EXTERN_INLINE.

rts: Fix capability-count check in zeroSlop
Previously `zeroSlop` examined `RtsFlags` to determine whether the

with `setNumCapabilities`. This lead to quite subtle and rare crashes.

Handle records in the renamer
This patch moves the field-based logic for disambiguating record updates
to the renamer. The type-directed logic, scheduled for removal, remains
in the typechecker.
To do this properly (and fix the myriad of bugs surrounding the treatment
of duplicate record fields), we took the following main steps:
1. Create GREInfo, a renamer-level equivalent to TyThing which stores
information pertinent to the renamer.
This allows us to uniformly treat imported and local Names in the
renamer, as described in Note [GREInfo].
2. Remove GreName. Instead of a GlobalRdrElt storing GreNames, which
distinguished between normal names and field names, we now store
simple Names in GlobalRdrElt, along with the new GREInfo information
which allows us to recover the FieldLabel for record fields.
3. Add namespacing for record fields, within the OccNames themselves.
This allows us to remove the mangling of duplicate field selectors.
This change ensures we don't print mangled names to the user in
error messages, and allows us to handle duplicate record fields
in Template Haskell.
4. Move record disambiguation to the renamer, and operate on the
level of data constructors instead, to handle #21443.
The error message text for ambiguous record updates has also been
changed to reflect that type-directed disambiguation is on the way
out.
(3) means that OccEnv is now a bit more complex: we first key on the
textual name, which gives an inner map keyed on NameSpace:
OccEnv a ~ FastStringEnv (UniqFM NameSpace a)
Note that this change, along with (2), both increase the memory residency
of GlobalRdrEnv = OccEnv [GlobalRdrElt], which causes a few tests to
regress somewhat in compile-time allocation.
Even though (3) simplified a lot of code (in particular the treatment of
field selectors within Template Haskell and in error messages), it came
with one important wrinkle: in the situation of
-- M.hs-boot
module M where { data A; foo :: A -> Int }
-- M.hs
module M where { data A = MkA { foo :: Int } }
we have that M.hs-boot exports a variable foo, which is supposed to match
with the record field foo that M exports. To solve this issue, we add a
new impedance-matching binding to M
foo{var} = foo{fld}
This mimics the logic that existed already for impedance-binding DFunIds,
but getting it right was a bit tricky.
See Note [Record field impedance matching] in GHC.Tc.Module.
We also needed to be careful to avoid introducing space leaks in GHCi.
So we dehydrate the GlobalRdrEnv before storing it anywhere, e.g. in
ModIface. This means stubbing out all the GREInfo fields, with the
function forceGlobalRdrEnv.
When we read it back in, we rehydrate with rehydrateGlobalRdrEnv.
This robustly avoids any space leaks caused by retaining old type
environments.

js: split JMacro into JS eDSL and JS syntax
This commit:
Splits JExpr and JStat into two nearly identical DSLs:
- GHC.JS.Syntax is the JMacro based DSL without unsaturation, i.e., a
value cannot be unsaturated, or, a value of this DSL is a witness that a
value of GHC.JS.Unsat has been saturated
- GHC.JS.Unsat is the JMacro DSL from GHCJS with Unsaturation.
Then all binary and outputable instances are changed to use
GHC.JS.Syntax.
This moves us closer to closing out #22736 and #22352. See #22736 for
roadmap.

ensure predictable output.
Fixes #23155.

Revert "ghc-heap: remove wrong Addr# coercion (#23181)"
This reverts commit f4f1f14f8009c3c120b8b963ec130cbbc774ec02.
This fails to build with GHC-9.2 as a boot compiler.

ci: make lint-ci-config job fast again
We don't pin our nixpkgs revision and tracks the default
nixpkgs-unstable channel anyway. Instead of using
haskell.packages.ghc924, we should be using haskell.packages.ghc92 to
maximize the binary cache hit rate and make lint-ci-config job fast
again. Also bumps the nix docker image to the latest revision.

We can safely enable parallel xz compression for non-i386 pipelines.
However, previously we didn't export XZ_OPT, so the xz process won't

testsuite: use context variable instead of thread-local variable
This patch changes a thread-local variable to context variable
instead, which works as intended when the testsuite transitions to use
asyncio & coroutines instead of multi-threading to concurrently run
test cases. Note that this also raises the minimum Python version to
3.7.

testsuite: asyncify the testsuite driver
This patch refactors the testsuite driver, gets rid of multi-threading
logic for running test cases concurrently, and uses asyncio &
coroutines instead. This is not yak shaving for its own sake; the
previous multi-threading logic is prone to livelock/deadlock
conditions for some reason, even if the total number of threads is
bounded to a thread pool's capacity.
The asyncify change is an internal implementation detail of the
testsuite driver and does not impact most GHC maintainers out there.
The patch does not touch the .T files, test cases can be
added/modified the exact same way as before.

we decided to revert these changes for now.

hadrian: Improve option parsing
Several options in Hadrian had their argument marked as optional
(`OptArg`), but if the argument wasn't there they were just giving an
error. It's more idiomatic to mark the argument as required instead;
the code uses less Maybes, the parser can enforce that the argument
is present, --help gives better output.

Fixes around unsafeCoerce#
1. `unsafeCoerce#` was documented in `GHC.Prim`. But since the overhaul
in 74ad75e87317, `unsafeCoerce#` is no longer defined there.
I've combined the documentation in `GHC.Prim` with the `Unsafe.Coerce` module.
2. The documentation of `unsafeCoerce#` stated that you should not
cast a function to an algebraic type, even if you later cast it back
before applying it. But ghci was doing that type of cast, as can be seen
with 'ghci -ddump-ds' and typing 'x = not'. I've changed it to use Any
following the documentation.

Add a few more memcpy-ish primops
* copyMutableByteArrayNonOverlapping#
* copyAddrToAddr#
* copyAddrToAddrNonOverlapping#
* setAddrRange#
The implementations of copyBytes, moveBytes, and fillBytes
in base:Foreign.Marshal.Utils now use these new primops,
which can cause us to work a bit harder generating code for them,
resulting in the metric increase in T21839c observed by CI on
some architectures. But in exchange, we get better code!

Relax assertion in varToRecFieldOcc
When using Template Haskell, it is possible to re-parent a field OccName
belonging to one data constructor to another data constructor. The
lsp-types package did this in order to "extend" a data constructor
with additional fields.
This ran into an assertion in 'varToRecFieldOcc'. This assertion
can simply be relaxed, as the resulting splices are perfectly sound.
Fixes #23220
