JS: replace "js" architecture with "javascript"
Despite Cabal supporting any architecture name, `cabal --check` only
supports a few built-in ones. Sadly `cabal --check` is used by Hackage
hence using any non built-in name in a package (e.g. `arch(js)`) is
rejected and the package is prevented from being uploaded on Hackage.
Luckily built-in support for the `javascript` architecture was added for
GHCJS a while ago. In order to allow newer `base` to be uploaded on
Hackage we make the switch from `js` to `javascript` architecture.
Fixes #22740.

Fix marking async exceptions in the JS backend

Don't allow . in overloaded labels
This patch removes . from the list of allowed characters in a non-quoted
overloaded label, as it was realised this steals syntax, e.g. (#.).
Users who want this functionality will have to add quotes around the
label, e.g. `#"17.28"`.

Revert "Use fix-sized equality primops for fixed size boxed types"
This reverts commit 024020c38126f3ce326ff56906d53525bc71690c.
This was never applied to master/9.6 originally.
See #20405 for why using these primops is a bad idea.

Fix tyvar scoping within class SPECIALISE pragmas
Type variables from class/instance headers scope over class/instance
method type signatures, but DO NOT scope over the type signatures in
SPECIALISE and SPECIALISE instance pragmas.
The logic in GHC.Rename.Bind.rnMethodBinds correctly accounted for
SPECIALISE inline pragmas, but forgot to apply the same treatment
to method SPECIALISE pragmas, which lead to a Core Lint failure with
an out-of-scope type variable. This patch makes sure we apply the same
logic for both cases.
Fixes #22913

Revert "Don't keep exit join points so much"
This reverts commit caced75765472a1a94453f2e5a439dba0d04a265.
It seems the patch "Don't keep exit join points so much" is causing
wide-spread regressions in the bytestring library benchmarks. If I
revert it then the 9.6 numbers are better on average than 9.4.

testsuite: use concurrent.futures.ThreadPoolExecutor in the driver
The testsuite driver used to create one thread per test case, and
explicitly use semaphore and locks for rate limiting and
synchronization. This is a bad practice in any language, and
occasionally may result in livelock conditions (e.g. #22889). This
patch uses concurrent.futures.ThreadPoolExecutor for scheduling test
case runs, which is simpler and more robust.

Refactor the simplifier a bit to fix #22761
The core change in this commit, which fixes #22761, is that
* In a Core rule, ru_rhs is always occ-analysed.
This means adding a couple of calls to occurAnalyseExpr when
building a Rule, in
* GHC.Core.Rules.mkRule
* GHC.Core.Opt.Simplify.Iteration.simplRules
But diagosing the bug made me stare carefully at the code of the
Simplifier, and I ended up doing some only-loosely-related refactoring.
* I think that RULES could be lost because not every code path
did addBndrRules
* The code around lambdas was very convoluted
It's mainly moving deck chairs around, but I like it more now.

RTS linker: Improve compatibility with NetBSD
1. Hint address to NetBSD mmap(2) has a different semantics from that of
Linux. When a hint address is provided, mmap(2) searches for a free
region at or below the hint but *never* above it. This means we can't
reliably search for free regions incrementally on the userland,
especially when ASLR is enabled. Let the kernel do it for us if we don't
care where the mapped address is going to be.
2. NetBSD not only hates to map pages as rwx, but also disallows to switch
pages from rw- to r-x unless the intention is declared when pages are
initially requested. This means we need a new MemoryAccess mode for
pages that are going to be changed to r-x.

Introduce warning for loopy superclass solve
Commit aed1974e completely re-engineered the treatment of loopy
superclass dictionaries in instance declarations. Unfortunately,
it has the potential to break (albeit in a rather minor way) user code.
To alleviate migration concerns, this commit re-introduces the old
behaviour. Any reliance on this old behaviour triggers a warning,
controlled by `-Wloopy-superclass-solve`. The warning text explains
that GHC might produce bottoming evidence, and provides a migration
strategy.
This allows us to provide a graceful migration period, alerting users
when they are relying on this unsound behaviour.

rts: make it possible to change mblock size on 32-bit targets
The MBLOCK_SHIFT macro must be the single source of truth for defining
the mblock size, and changing it should only affect performance, not
correctness. This patch makes it truly possible to reconfigure mblock
size, at least on 32-bit targets, by fixing places which implicitly
relied on the previous MBLOCK_SHIFT constant. Fixes #22901.

switches based on whether the codegen is unregisterised, but there do
exist registerised builds that disable tables-next-to-code! This patch
corrects that problem. Fixes #22896.

Narrow the dont-decompose-newtype test
Following #22924 this patch narrows the test that stops
us decomposing newtypes. The key change is the use of
noGivenNewtypeReprEqs in GHC.Tc.Solver.Canonical.canTyConApp.
We went to and fro on the solution, as you can see in #22924.
The result is carefully documented in

Commit cfc8e2e2 introduced a mechanism for handling of exceptions
that occur during Handle finalization, and 372cf730 set the default

as it might pollute users' terminals with unwanted information.

Add INLINABLE pragmas to `generic*` functions in Data.OldList
These functions are

So it's important to add an `INLINABLE` pragma to each so that they can be

Merge libiserv with ghci
`libiserv` serves no purpose. As it depends on `ghci` and doesn't have
more dependencies than the `ghci` package, its code could live in the
`ghci` package too.
This commit also moves most of the code from the `iserv` program into
the `ghci` package as well so that it can be reused. This is especially
useful for the implementation of TH for the JS backend (#22261, !9779).

compiler: fix cost centre profiling breakage in wasm NCG due to incorrect register mapping
The wasm NCG used to map CCCS to a wasm global, based on the
observation that CCCS is a transient register that's already handled
by thread state load/store logic, so it doesn't need to be backed by
the rCCCS field in the register table.
Unfortunately, this is wrong, since even when Cmm execution hasn't
yielded back to the scheduler, the Cmm code may call enterFunCCS,
which does use rCCCS.
This breaks cost centre profiling in a subtle way, resulting in
inaccurate stack traces in some test cases. The fix is simple though:
just remove the CCCS mapping.

Don't generate datacon wrappers for `type data` declarations
Data constructor wrappers only make sense for _value_-level data constructors,
but data constructors for `type data` declarations only exist at the _type_
level. This patch does the following:
* The criteria in `GHC.Types.Id.Make.mkDataConRep` for whether a data
constructor receives a wrapper now consider whether or not its parent data
type was declared with `type data`, omitting a wrapper if this is the case.
* Now that `type data` data constructors no longer receive wrappers, there is a
spot of code in `refineDefaultAlt` that panics when it encounters a value
headed by a `type data` type constructor. I've fixed this with a special case
in `refineDefaultAlt` and expanded `Note [Refine DEFAULT case alternatives]`
to explain why we do this.

GHC proposal 496 - Nullary record wildcards
This patch implements GHC proposal 496, which allows record wildcards
to be used for nullary constructors, e.g.
data A = MkA1 | MkA2 { fld1 :: Int }
f :: A -> Int
f (MkA1 {..}) = 0
f (MkA2 {..}) = fld1
To achieve this, we add arity information to the record field
environment, so that we can accept a constructor which has no fields
while continuing to reject non-record constructors with more than 1
field. See Note [Nullary constructors and empty record wildcards],
as well as the more general overview in Note [Local constructor info in the renamer],
both in the newly introduced GHC.Types.ConInfo module.
Fixes #22161

Don't specialise incoherent instance applications
Using incoherent instances, there can be situations where two
occurrences of the same overloaded function at the same type use two
different instances (see #22448). For incoherently resolved instances,
we must mark them with `nospec` to avoid the specialiser rewriting one
to the other. This marking is done during the desugaring of the
`WpEvApp` wrapper.

Account for local rules in specImports
As #23024 showed, in GHC.Core.Opt.Specialise.specImports, we were
generating specialisations (a locally-define function) for imported
functions; and then generating specialisations for those
locally-defined functions. The RULE for the latter should be
attached to the local Id, not put in the rules-for-imported-ids
set.
Fix is easy; similar to what happens in GHC.HsToCore.addExportFlagsAndRules

hadrian: Add dependency from lib/settings to mk/config.mk
In 81975ef375de07a0ea5a69596b2077d7f5959182 we attempted to fix #20253
by adding logic to the bindist Makefile to regenerate the `settings`
file from information gleaned by the bindist `configure` script.
However, this fix had no effect as `lib/settings` is shipped in the
binary distribution (to allow in-place use of the binary distribution).
As `lib/settings` already existed and its rule declared no dependencies,
`make` would fail to use the added rule to regenerate it.
Fix this by explicitly declaring a dependency from `lib/settings` on
`mk/config.mk`.
Fixes #22982.

Constraint simplification loop now depends on `ExpansionFuel`
instead of a boolean flag for `CDictCan.cc_pend_sc`.
Pending givens get a fuel of 3 while Wanted and quantified constraints get a fuel of 1.

nonmoving: Fix handling of weak pointers
This fixes an interaction between aging and weak pointer handling which
prevented the finalization of some weak pointers. In particular, weak
pointers could have their keys incorrectly marked by the preparatory
collector, preventing their finalization by the subsequent concurrent
collection.
While in the area, we also significantly improve the assertions
regarding weak pointers.
Fixes #22327.

nonmoving: Sync-phase mark budgeting
Here we significantly improve the bound on sync phase pause times by
imposing a limit on the amount of work that we can perform during the
sync. If we find that we have exceeded our marking budget then we allow
the mutators to resume, return to concurrent marking, and try
synchronizing again later.
Fixes #22929.

nonmoving: Move current segment array into Capability
The current segments are conceptually owned by the mutator, not the
collector. Consequently, it was quite tricky to prove that the mutator
would not race with the collect due to this shared state. It turns out
that such races are possible: when resizing the current segment array
we may concurrently try to take a heap census. This will attempt to walk
the current segment array, causing a data race.
Fix this by moving the current segment array into `Capability`, where it
belongs.
Fixes #22926.

rts/Sanity: Fix block count assertion with non-moving collector
The nonmoving collector does not use `oldest_gen->blocks` to track its
block list. However, it nevertheless updates `oldest_gen->n_blocks` to
ensure that its size is accounted for by the storage manager.
Consequently, we must not attempt to assert consistency between the two.

nonmoving: Don't call prepareUnloadCheck
When the nonmoving GC is in use we do not call `checkUnload` (since we
don't unload code) and therefore should not call `prepareUnloadCheck`,
lest we run into assertions.

hadrian: Fix flavour compiler stage options off-by-one error
!9193 pointed out that ghcDebugAssertions was supposed to be a predicate
on the stage of the built compiler, but in practice it was a predicate
on the stage of the compiler used to build. Unfortunately, while it
fixed that issue for ghcDebugAssertions, it documented every other
similar option as behaving the same way when in fact they all used the
old behavior.
The new behavior of ghcDebugAssertions seems more intuitive, so this
commit changes the interpretation of every other option to match. It
also improves the enableProfiledGhc and debugGhc flavour transformers by
making them more selective about which stages in which they build
additional library/RTS ways.

Fixes #19627.
Previously the solver failed with an unhelpful "solver reached too may iterations" error.
With the fix for #21909 in place we no longer have the possibility of generating such an error if we have `-fconstraint-solver-iteration` > `-fgivens-fuel > `-fwanteds-fuel`. This is true by default, and the said fix also gives programmers a knob to control how hard the solver should try before giving up.
This commit adds:
* Reference to ticket #19627 in the Note [Expanding Recursive Superclasses and ExpansionFuel]
* Test `typecheck/should_fail/T19627.hs` for regression purposes
