This reverts commit d0d7ba0fb053ebe7f919a5932066fbc776301ccd.
The module now lacks a dependency on GHC.Num.BigNat which it implicitly
depends on. It is causing all CI jobs to fail so we revert without haste
whilst the patch can be fixed.
Fixes #22848

Detect family instance orphans correctly
We were treating a type-family instance as a non-orphan if there
was a type constructor on its /right-hand side/ that was local. Boo!
Utterly wrong. With this patch, we correctly check the /left-hand side/
instead!
Fixes #22717

Report family instance orphans correctly
This fixes the fact that we were not reporting orphan family instances
at all. The fix here is easy, but touches a bit of code. I refactored
the code to be much more similar to the way that class instances are done:
- Add a fi_orphan field to FamInst, like the is_orphan field in ClsInst
- Make newFamInst initialise this field, just like newClsInst
- And make newFamInst report a warning for an orphan, just like newClsInst
- I moved newFamInst from GHC.Tc.Instance.Family to GHC.Tc.Utils.Instantiate,
just like newClsInst.
- I added mkLocalFamInst to FamInstEnv, just like mkLocalClsInst in InstEnv
- TcRnOrphanInstance and SuggestFixOrphanInstance are now parametrised
over class instances vs type/data family instances.
Fixes #19773

CApiFFI: add ConstPtr for encoding const-qualified pointer return types
Previously, when using `capi` calling convention in foreign declarations,
code generator failed to handle const-cualified pointer return types.
This resulted in CC toolchain throwing `-Wincompatible-pointer-types-discards-qualifiers`
warning.
`Foreign.C.Types.ConstPtr` newtype was introduced to handle these cases -
special treatment was put in place to generate appropritetly qualified C
wrapper that no longer triggers the above mentioned warning.

hadrian: Fix library-dirs, dynamic-library-dirs and static-library-dirs in inplace .conf files
Previously we were just throwing away the contents of the library-dirs
fields but really we have to do the same thing as for include-dirs,
relativise the paths into the current working directory and maintain any
extra libraries the user has specified.
Now the relevant section of the rts.conf file looks like:
```
library-dirs:

nativeGen: Disable asm-shortcutting on Darwin
Asm-shortcutting may produce relative references to symbols defined in
other compilation units. This is not something that MachO relocations
support (see #21972). For this reason we disable the optimisation on
Darwin. We do so without a warning since this flag is enabled by `-O2`.
Another way to address this issue would be to rather implement a
PLT-relocatable jump-table strategy. However, this would only benefit
Darwin and does not seem worth the effort.
Closes #21972.

compiler: fix data section alignment in the wasm NCG
Previously we tried to lower the alignment requirement as far as
possible, based on the section kind inferred from the CLabel. For info
tables, .p2align 1 was applied given the GC should only need the
lowest bit to tag forwarding pointers. But this would lead to
unaligned loads/stores, which has a performance penalty even if the
wasm spec permits it. Furthermore, the test suite has shown memory
corruption in a few cases when compacting gc is used.
This patch takes a more conservative approach: all data sections
except C strings align to word size.

ghc-the-library: Retain cafs in both static in dynamic builds.
We use keepCAFsForGHCi.c to force -fkeep-cafs behaviour by using a
__attribute__((constructor)) function.
This broke for static builds where the linker discarded the object file
since it was not reverenced from any exported code. We fix this by
asserting that the flag is enabled using a function in the same module
as the constructor. Which causes the object file to be retained by the
linker, which in turn causes the constructor the be run in static builds.
This changes nothing for dynamic builds using the ghc library. But causes
static to also retain CAFs (as we expect them to).
Fixes #22417.

Handle `type data` properly in tyThingParent_maybe
Unlike most other data constructors, data constructors declared with `type data`
are represented in `TyThing`s as `ATyCon` rather than `ADataCon`. The `ATyCon`
case in `tyThingParent_maybe` previously did not consider the possibility of
the underlying `TyCon` being a promoted data constructor, which led to the
oddities observed in #22817. This patch adds a dedicated special case in
`tyThingParent_maybe`'s `ATyCon` case for `type data` data constructors to fix
these oddities.
Fixes #22817.

* `type data` data constructors are now properly reified using `DataConI`.
This is accomplished with a special case in `reifyTyCon`. Fixes #22818.
* `type data` type constructors are now reified in `reifyTyCon` using
`TypeDataD` instead of `DataD`. Fixes #22819.

Take account of loop breakers in specLookupRule
The key change is that in GHC.Core.Opt.Specialise.specLookupRule
we were using realIdUnfolding, which ignores the loop-breaker
flag. When given a loop breaker, rule matching therefore
looped infinitely -- #22802.
In fixing this I refactored a bit.
* Define GHC.Core.InScopeEnv as a data type, and use it.
(Previously it was a pair: hard to grep for.)
* Put several functions returning an IdUnfoldingFun into
GHC.Types.Id, namely
idUnfolding
alwaysActiveUnfoldingFun,
whenActiveUnfoldingFun,
noUnfoldingFun
and use them. (The are all loop-breaker aware.)

User's guide: Clarify overlapping instance candidate elimination
This commit updates the user's guide section on overlapping instance candidate
elimination to use "or" verbiage instead of "either/or" in regards to the
current pair of candidates' being overlappable or overlapping. "Either IX is
overlappable, or IY is overlapping" can cause confusion as it suggests "Either
IX is overlappable, or IY is overlapping, but not both".

Improve exprOkForSpeculation for classops
This patch fixes #22745 and #15205, which are about GHC's
failure to discard unnecessary superclass selections that
yield coercions. See
GHC.Core.Utils Note [exprOkForSpeculation and type classes]
The main changes are:
* Write new Note [NON-BOTTOM_DICTS invariant] in GHC.Core, and
refer to it
* Define new function isTerminatingType, to identify those
guaranteed-terminating dictionary types.
* exprOkForSpeculation has a new (very simple) case for ClassOpId
* ClassOpId has a new field that says if the return type is
an unlifted type, or a terminating type.
This was surprisingly tricky to get right. In particular note
that unlifted types are not terminating types; you can write an
expression of unlifted type, that diverges. Not so for dictionaries
(or, more precisely, for the dictionaries that GHC constructs).

Bump supported LLVM range from 10 through 15 to 11 through 16
LLVM 15 turns on the new pass manager by default, which we have yet to
migrate to so for new we pass the `-enable-new-pm-0` flag in our
llvm-passes flag.
LLVM 11 was the first version to support the `-enable-new-pm` flag so we
bump the lowest supported version to 11.
Our CI jobs are using LLVM 12 so they should continue to work despite
this bump to the lower bound.

CI: JavaScript backend runs testsuite
This MR runs the testsuite for the JS backend. Note that this is a
temporary solution until !9515 is merged.
Key point: The CI runs hadrian on the built cross compiler _but not_ on
the bindist.
Other Highlights:
- stm submodule gets a bump to mark tests as broken
- several tests are marked as broken or are fixed by adding more
- conditions to their test runner instance.
List of working commit messages:
CI: test cross target _and_ emulator
CI: JS: Try run testsuite with hadrian
JS.CI: cleanup and simplify hadrian invocation
use single bracket, print info
JS CI: remove call to test_compiler from hadrian
don't build haddock
JS: mark more tests as broken
Tracked in https://gitlab.haskell.org/ghc/ghc/-/issues/22576
JS testsuite: don't skip sum_mod test
Its expected to fail, yet we skipped it which automatically makes it
succeed leading to an unexpected success,
JS testsuite: don't mark T12035j as skip
leads to an unexpected pass
JS testsuite: remove broken on T14075
leads to unexpected pass
JS testsuite: mark more tests as broken
JS testsuite: mark T11760 in base as broken
JS testsuite: mark ManyUnbSums broken
submodules: bump process and hpc for JS tests
Both submodules has needed tests skipped or marked broken for th JS
backend. This commit now adds these changes to GHC.

Disable unfolding sharing for interface files with core definitions
Ticket #22807 pointed out that the RHS sharing was not compatible with
-fignore-interface-pragmas because the flag would remove unfoldings from
identifiers before the `extra-decls` field was populated.
For the 9.6 timescale the only solution is to disable this sharing,
which will make interface files bigger but this is acceptable for the
first release of `-fwrite-if-simplified-core`.
For 9.8 it would be good to fix this by implementing #20056 due to the
large number of other bugs that would fix.
I also improved the error message in tc_iface_binding to avoid the "no match
in record selector" error but it should never happen now as the entire
sharing logic is disabled.
Also added the currently broken test for #22807 which could be fixed by
!6080
Fixes #22807

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 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.

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.

nativeGen/AArch64: Emit Atomic{Read,Write} inline
Previously the AtomicRead and AtomicWrite operations were emitted as
out-of-line calls. However, these tend to be very important for
performance, especially the RELAXED case (which only exists for
ThreadSanitizer checking).

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.

Documentation: Improve Foldable1 documentation
* Explain foldrMap1, foldlMap1, foldlMap1', and foldrMap1' in greater
detail, the text is mostly adapted from documentation of Foldable.
* Describe foldr1, foldl1, foldl1' and foldr1' in terms of the above
functions instead of redoing the full explanation.
* Small updates to documentation of fold1, foldMap1 and toNonEmpty,
again adapting from Foldable.
* Update the foldMap1 example to lists instead of Sum since this is
recommended for lazy right-associative folds.

fix: Mark ghci Prelude import as implicit

compiler: fix generateCgIPEStub for no-tables-next-to-code builds
generateCgIPEStub already correctly implements the CmmTick finding
logic for when tables-next-to-code is on/off, but it used the wrong
predicate to decide when to switch between the two. Previously it
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
Note [Decomoposing newtype equalities]
On the way I had revert most of
commit 3e827c3f74ef76d90d79ab6c4e71aa954a1a6b90

Do newtype unwrapping in the canonicaliser and rewriter
See Note [Unwrap newtypes first], which has the details.
It turns out that
(a) 3e827c3f makes GHC behave worse on some recursive newtypes
(see one of the tests on this commit)
(b) the finer-grained test (namely noGivenNewtypeReprEqs) renders
3e827c3f unnecessary

No default finalizer exception handler
Commit cfc8e2e2 introduced a mechanism for handling of exceptions
that occur during Handle finalization, and 372cf730 set the default
handler to print out the error to stderr.
However, #21680 pointed out we might not want to set this by default,
as it might pollute users' terminals with unwanted information.
So, for the time being, the default handler discards the exception.

unicode: Don't inline bitmap in generalCategory
generalCategory contains a huge literal string but is marked INLINE,
this will duplicate the string into any use site of generalCategory. In
particular generalCategory is used in functions like isSpace and the
literal gets inlined into this function which makes it massive.

Add INLINABLE pragmas to `generic*` functions in Data.OldList
These functions are
* recursive
* overloaded
So it's important to add an `INLINABLE` pragma to each so that they can be
specialised at the use site when the specific numeric type is known.
Adding these pragmas improves the LazyText replicate benchmark (see https://gitlab.haskell.org/ghc/ghc/-/issues/22886#note_481020)

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.
