hadrian may invoke findExecutable "" at run-time due to a certain
program is not found by configure script. Which is fine and
findExecutable is supposed to return Nothing in this case. However, on
Windows there's a directory bug that throws an exception (see
https://github.com/haskell/directory/issues/180), so we might as well
use a wrapper for findExecutable and handle exceptions gracefully.

When configure fails to find LLC/OPT/LLVMAS within supported version
range, it used to set "llc"/"opt"/"clang" as fallback values. This
behavior is particularly troublesome when the user has llc/opt/clang
with other versions in their PATH and run the testsuite, since hadrian
will incorrectly assume have_llvm=True and pass that to the testsuite
driver, resulting in annoying optllvm test failures (#23186). If
configure determines llc/opt/clang wouldn't work, then we shouldn't
pretend it'll work at all, and the bindist configure will invoke
FIND_LLVM_PROG check again at install time anyway.

ucd2haskell tool used streamly library which version in cabal was out of date. It is updated to the latest version at hackage with deprecated parts rewritten.
Also following fixes were applied to existing code in suppose that from its last run the code structure was changed and now it was required to be up to date with actual folder structures:
1. Ghc module path environment got a suffix with `src`.
2. Generated code got
2.1 `GHC.Internal` prefix for `Data.*`.
2.2 `GHC.Unicode.Internal` swapped on `GHC.Internal.Unicode` according to actual structure.

For each module in a GHCi session, we keep alive one `ModLocation`.
A `ModLocation` is fairly inefficiently packed, as `String`s are
expensive in memory usage.
While benchmarking the agda codebase, we concluded that we keep alive
around 11MB of `FilePath`'s, solely retained by `ModLocation`.
We provide a more densely packed encoding of `ModLocation`, by moving
from `FilePath` to `OsPath`. Further, we migrate the full `Finder`
component to `OsPath` to avoid unnecessary transformations.
As the `Finder` component is well-encapsulated, this requires only a
minimal amount of changes in other modules.
We introduce pattern synonym for 'ModLocation' which maintains backwards
compatibility and avoids breaking consumers of 'ModLocation'.

This commit introduces a new language extension, `-XOrPatterns`, as described in
GHC Proposal 522.
An or-pattern `pat1; ...; patk` succeeds iff one of the patterns `pat1`, ...,
`patk` succeed, in this order.
See also the summary `Note [Implmentation of OrPatterns]`.

We have formally dropped i386 windows support (#18487) a long time
ago. The stdcall foreign call convention is only used by i386 windows,
and the legacy logic around it is a significant maintenance burden for
future work that adds arm64 windows support (#24603). Therefore, this
patch removes stdcall support completely from the compiler as well as
the RTS (#24883):
- stdcall is still recognized as a FFI calling convention in Haskell
syntax. GHC will now unconditionally emit a warning
(-Wunsupported-calling-conventions) and treat it as ccall.
- Apart from minimum logic to support the parsing and warning logic,
all other code paths related to stdcall has been completely stripped
from the compiler.
- ghci only supports FFI_DEFAULT_ABI and ccall convention from now on.
- FFI foreign export adjustor code on all platforms no longer handles
the stdcall case and only handles ccall from now on.
- The Win32 specific parts of RTS no longer has special code paths for
stdcall.
This commit is the final nail on the coffin for i386 windows support.
Further commits will perform more housecleaning to strip the legacy
code paths and pave way for future arm64 windows support.

This patch adjusts test cases to handle the stdcall removal:
- Some stdcall usages are replaced with ccall since stdcall doesn't
make sense anymore.
- We also preserve some stdcall usages, and check in the expected
warning messages to ensure GHC always warn about stdcall usages
(-Wunsupported-calling-conventions) as expected.
- Error code testsuite coverage is slightly improved,
-Wunsupported-calling-conventions is now tested.
- Obsolete code paths related to i386 windows are also removed.

In pursuit of: #22736.
This MR moves ad-hoc symbols used throughout the js backend into a
single symbols file. Why? First, this cleans up the code by removing
ad-hoc strings created on the fly and therefore makes the code more
maintainable. Second, it makes it much easier to eventually type these
identifiers.

This MR fixes the bug exposed by #24676. The problem was that
quickLookArg was trying to avoid calling tcInstFun unnecessarily; but
it was in fact necessary. But that in turn forced me into a
significant refactoring, putting more fields into EValArgQL.
Highlights: see Note [Quick Look overview] in GHC.Tc.Gen.App
* Instantiation variables are now distinguishable from ordinary
unification variables, by level number = QLInstVar. This is
treated like "level infinity". See Note [The QLInstVar TcLevel]
in GHC.Tc.Utils.TcType.
* In `tcApp`, we don't track the instantiation variables in a set Delta
any more; instead, we just tell them apart by their level number.
* EValArgQL now much more clearly captures the "half-done" state
of typechecking an argument, ready for later resumption.
See Note [Quick Look at value arguments] in GHC.Tc.Gen.App
* Elminated a bogus (never used) fast-path in
GHC.Tc.Utils.Instantiate.instCallConstraints
See Note [Possible fast path for equality constraints]
Many other small refactorings.

The main payload of this patch is
* Prioritise nominal equalities in the constraint solver. This
ameliorates the incompleteness of solving for representational
constraints over newtypes: see #24887.
See (EX2) in Note [Decomposing newtype equalities] in
GHC.Tc.Solver.Equality
In doing this patch I tripped over some other things that I refactored:
* Move `isCoVarType` from `GHC.Core.Type` to `GHC.Core.Predicate`
where it seems more at home.
* Clarify the "rewrite role" of a constraint. I was very puzzled
about what the role of, say `(Eq a)` might be, but see the new
Note [The rewrite-role of a constraint].
In doing so I made predTypeEqRel crash when given a non-equality.
Usually it expects an equality; but it was being mis-used for
the above rewrite-role stuff.

This MR was triggered by #24868, but I found a number of bugs
and infelicities in type-tidying as I went along. Highlights:
* Fix to #24868 is in GHC.Tc.Errors.report_unsolved: avoid
using the OccNames of /bound/ variables when tidying /free/
variables; see the call to `tidyAvoiding`. That avoid the
gratuitous renaming which was the cause of #24868. See
Note [tidyAvoiding] in GHC.Core.TyCo.Tidy
* Refactor and document the tidying of open types.
See GHC.Core.TyCo.Tidy
Note [Tidying open types]
Note [Tidying is idempotent]
* Tidy the coercion variable in HoleCo. That's important so
that tidied types have tidied kinds.
* Some small renaming to make things consistent. In particular
the "X" forms return a new TidyEnv. E.g.
tidyOpenType :: TidyEnv -> Type -> Type
tidyOpenTypeX :: TidyEnv -> Type -> (TidyEnv, Type)

This commit introduces the RTS flag `--read-tix-file=<yes|no>` which
controls whether a preexisting .tix file is read in at the beginning
of a program run. The default is currently `--read-tix-file=yes` but
will change to `--read-tix-file=no` in a future release of GHC. For
this reason, whenever a .tix file is read in a warning is emitted to
stderr. This warning can be silenced by explicitly passing the
`--read-tix-file=yes` option. Details can be found in the GHC proposal
cited below.
Users can query whether this flag has been used with the help of the
module `GHC.RTS.Flags`. A new field `readTixFile` was added to the
record `HpcFlags`.
These changes have been discussed and approved in

As a `ModIface` often contains duplicated values that are not
necessarily shared, we improve sharing by serialising the `ModIface`
to an in-memory byte array. Serialisation uses deduplication tables, and
deserialisation implicitly shares duplicated values.
This helps reducing the peak memory usage while compiling in
`--make` mode. The peak memory usage is especially smaller when
generating interface files with core expressions
(`-fwrite-if-simplified-core`).
On agda, this reduces the peak memory usage:
* `2.2 GB` to `1.9 GB` for a ghci session.
On `lib:Cabal`, we report:
* `570 MB` to `500 MB` for a ghci session
* `790 MB` to `667 MB` for compiling `lib:Cabal` with ghc
There is a small impact on execution time, around 2% on the agda code
base.

To reduce memory usage of `ModIface`, we serialise `ModIface` to an
in-memory byte array, which implicitly shares duplicated values.
This serialised byte array can be reused to avoid work when we actually
write the `ModIface` to disk.
We introduce a new field to `ModIface` which allows us to save the byte
array, and write it direclty to disk if the `ModIface` wasn't changed
after the initial serialisation.
This requires us to change absolute offsets, for example to jump to the
deduplication table for `Name` or `FastString` with relative offsets, as
the deduplication byte array doesn't contain header information, such as
fingerprints.
To allow us to dump the binary blob to disk, we need to replace all
absolute offsets with relative ones.
We introduce additional helpers for `ModIface` binary serialisation, which
construct relocatable binary blobs. We say the binary blob is relocatable,
if the binary representation can be moved and does not contain any
absolute offsets.
Further, we introduce new primitives for `Binary` that allow to create
relocatable binaries, such as `forwardGetRel` and `forwardPutRel`.

-------------------------
These metric increases may look bad, but they are all completely benign,
we simply allocate 1 MB per module for `shareIface`. As this allocation
is quite quick, it has a negligible impact on run-time performance.
In fact, the performance difference wasn't measurable on my local
machine. Reducing the size of the pre-allocated 1 MB buffer avoids these
test failures, but also requires us to reallocate the buffer if the
interface file is too big. These reallocations *did* have an impact on
performance, which is why I have opted to accept all these metric
increases, as the number of allocated bytes is merely a guidance.
This 1MB allocation increase causes a lot of tests to fail that
generally have a low allocation number. E.g., increasing from 40MB to
41MB is a 2.5% increase.
In particular, the tests T12150, T13253-spj, T18140, T18304, T18698a,
T18923, T20049, T24582, T5837, T6048, and T9961 only fail on i386-darwin
job, where the number of allocated bytes seems to be lower than in other
jobs.
The tests T16875 and T18698b fail on i386-linux for the same reason.

This MR tackles #24623 and #23113
The main change is to give a clearer notion of "worker/wrapper arity", esp
for join points. See GHC.Core.Opt.DmdAnal
Note [Worker/wrapper arity and join points]
This Note is a good summary of what this MR does:
(1) The "worker/wrapper arity" of an Id is
* For non-join-points: idArity
* The join points: the join arity (Id part only of course)
This is the number of args we will use in worker/wrapper.
See `ww_arity` in `dmdAnalRhsSig`, and the function `workWrapArity`.
(2) A join point's demand-signature arity may exceed the Id's worker/wrapper
arity. See the `arity_ok` assertion in `mkWwBodies`.
(3) In `finaliseArgBoxities`, do trimBoxity on any argument demands beyond
the worker/wrapper arity.
(4) In WorkWrap.splitFun, make sure we split based on the worker/wrapper
arity (re)-computed by workWrapArity.

This commit enables some extensions and GHC flags in the cabal file in a way
that allows us to reduce the amount of prologuing on top of each file.
We also prefix the usage of some List functions that removes ambiguity
when they are also exported from the Prelude, like foldl'.
In general, this has the effect of pointing out more explicitly
that a linked list is used.

When matching a template variable to an expression, we check that it
has the same type as the matched expression. But if the variable `f` has
type `A -> B` while the expression `e` has type `A %1 -> B`, the match was
previously rejected.
A principled solution would have `f` substituted by `\(%Many x) -> e
x` or some other appropriate coercion. But since linearity is not
properly checked in Core, we can be cheeky and simply ignore
multiplicity while matching. Much easier.
This has forced a change in the linter which, when `-dlinear-core-lint`
is off, must consider that `a -> b` and `a %1 -> b` are equal. This is
achieved by adding an argument to configure the behaviour of
`nonDetCmpTypeX` and modify `ensureEqTys` to call to the new behaviour
which ignores multiplicities when comparing two `FunTy`.
Fixes #24725.

This MR speeds up type equality, triggered by perf regressions that
showed up when fixing #24725 by parameterising type equality over
whether to ignore multiplicity.
The changes are:
* Do not use `nonDetCmpType` for type /equality/. Instead use a specialised
type-equality function, which we have always had!
`nonDetCmpType` remains, but I did not invest effort in refactoring
or optimising it.
* Type equality is parameterised by
- whether to expand synonyms
- whether to respect multiplicities
- whether it has a RnEnv2 environment
In this MR I systematically specialise it for static values of these
parameters. Much more direct and predictable than before. See
Note [Specialising type equality]
* We want to avoid comparing kinds if possible. I refactored how this
happens, at least for `eqType`.
See Note [Casts and coercions in type comparison]
* To make Lint fast, we want to avoid allocating a thunk for <msg> in
ensureEqTypes ty1 ty2 <msg>
because the test almost always succeeds, and <msg> isn't needed.
See Note [INLINE ensureEqTys]

The pervasive usage of DynFlags (the parsed command-line options passed
to ghc) blurs the border between different components of Haddock, and
especially those that focus solely on printing text on the screen.
In order to improve the understanding of the real dependencies of a
function, the pretty-printer options are made concrete earlier in the
pipeline instead of late when pretty-printing happens.
This also has the advantage of clarifying which functions actually
require DynFlags for purposes other than pretty-printing, thus making
the interactions between Haddock and GHC more understandable when
exploring the code base.
See Henry, Ericson, Young. "Modularizing GHC".

To allow rules to be written on the concrete implementation of
`compare` for `Int` and `Word`, we need to have an `INLINE [1]`
pragma on these functions, following the
`matching_overloaded_methods_in_rules` note in `GHC.Classes`.

It is non-obvious whether the toolchain configuration should use
full-paths to tools or simply their names. In addressing #24574, we've
decided to prefer executable names over paths, ultimately, because the
bindist configure script already does this, thus is the default in ghcs
out there.
Updates the in-tree configure script to prefer tool names
(`AC_CHECK_TOOL` rather than `AC_PATH_TOOL`) and `ghc-toolchain` to
ignore the full-path-result of `findExecutable`, which it previously
used over the program name.
This change doesn't undo the fix in bd92182cd56140ffb2f68ec01492e5aa6333a8fc
because `AC_CHECK_TOOL` still takes into account the target triples,
unlike `AC_CHECK_PROG/AC_PATH_PROG`.

LlvmTarget was being set and substituted in the in-tree configure, but
not in the configure shipped in the bindist.
We want to set the LlvmTarget to the canonical LLVM name of the platform
that GHC is targetting.
Currently, that is going to be the boostrapped llvm target (hence the
code which sets LlvmTarget=bootstrap_llvm_target).

- Without TNTC (tables-next-to-code), we must be careful to not
duplicate labels in pprNatCmmDecl. Especially, as a CmmProc is
identified by the label of its entry block (and not of its info
table), we can't reuse the same label to delimit the block end and the
proc end.
- We generate debug infos from Cmm blocks. However, when
asm-shortcutting is enabled, some blocks are dropped at the asm
codegen stage and some labels in the DebugBlocks become missing.
We fix this by filtering the generated debug-info after the asm
codegen to only keep valid infos.
Also add some related documentation.

addr2Int# and int2Addr# were marked as deprecated with the introduction
of the OCaml code generator (1dfaee318171836b32f6b33a14231c69adfdef2f)
due to its use of tagged integers. However, this backend has long
vanished and `base` has all along been using `addr2Int#` in the Show
instance for Ptr.
While it's unlikely that we will have another backend which has tagged
integers, we may indeed support platforms which have tagged pointers.
Consequently we undeprecate the operations but warn the user that the
operations may not be portable.

We use live words rather than live blocks to determine the size of the
heap for determining memory retention.
Most of the time these two metrics align, but they can come apart in
normal usage when using the nonmoving collector.
The nonmoving collector leads to a lot of partially occupied blocks. So,
using live words is more accurate.
They can also come apart when the heap is suffering from high levels
fragmentation caused by small pinned objects, but in this case, the
block size is the more accurate metric. Since this case is best avoided
anyway. It is ok to accept the trade-off that we might try (and
probably) fail to return more memory in this case.
See also the Note [Statistics for retaining memory]

* drop stale comment in GHC.Iface.Load;
* reduce noise in -v3 traces from GHC.Utils.TmpFs;
* new test, which also exercizes HomeModError.

Progress towards #21592
This splits HsSrcBang up, creating the new HsBang within
`Language.Haskell.Syntax.Basic`. `HsBang` holds the unpackedness
and strictness information, while `HsSrcBang` only adds the SourceText
for usage within the compiler directly.
Inside the AST, to preserve the SourceText, it is hidden behind the
pre-existing extension point `XBindTy`. All other occurrences of
`HsSrcBang` were adapted to deconstruct the inner `HsBang`, and when
interacting with the `BindTy` constructor, the hidden `SourceText` is
extracted/inserted into the `XBindTy` extension point.
`GHC.Core.DataCon` exports both `HsSrcBang` and `HsBang` for
convenience. A constructor function `mkHsSrcBang` that takes all
individual components has been added.
Two exceptions has been made though:
- The `Outputable HsSrcBang` instance is replaced by
`Outputable HsBang`. While being only GHC-internal, the only place
it's used is in outputting `HsBangTy` constructors -- which already
have `HsBang`. It wouldn't make sense to reconstruct a `HsSrcBang` just
to ignore the `SourceText` anyway.
- The error `TcRnUnexpectedAnnotation` did not use the `SourceText`,
so it too now only holds a `HsBang`.

There is some convoluted logic which determines whether we build ghci
object files are not. In any case, if you set `ghcDynPrograms = pure
False` then it forces them to be built.
Given we aren't ever building executables with this flavour it's fine
to leave `ghcDynPrograms` as the default and it should be a bit faster
to build less.

would remove the need for workarounds in hadrian but for now we can

It is sufficient to check that the simple test file compiles as it will

If you break a way so badly that even a simple executable fails to link

that way are skipped on CI rather than displayed.

The main payload of this change is to hadrian.
* Default settings will produced dynamic profiled objects
* `-fexternal-interpreter` is turned on in some situations when there is
an incompatibility between host GHC and the way attempting to be
built.
* Very few changes actually needed to GHC
There are also necessary changes to the bootstrap plans to work with the
vendored Cabal dependency. These changes should ideally be reverted by
the next GHC release.
In hadrian support is added for building profiled dynamic libraries
(nothing too exciting to see there)
Updates hadrian to use a vendored Cabal submodule, it is important that
we replace this usage with a released version of Cabal library before
the 9.12 release.

instead of producing a foreign call a C function.
In `tar`, the hot loop for `deserialise` got almost 4x faster by
avoiding the foreign call which caused spilling live variables to the
stack -- this means the loop did 4x more memory read/writing than
necessary in that particular case!

This patch ensures we taken into account COMPLETE pragmas when we
compute whether a pattern is irrefutable. In particular, if a pattern
synonym is the sole member of a COMPLETE pragma (without a result TyCon),
then we consider a pattern match on that pattern synonym to be irrefutable.
This affects the desugaring of do blocks, as it ensures we don't use
a "fail" operation.

As #25096 showed, the occurrence analyser was getting one-shot info
flat out wrong.
This commit does two things:
* It fixes the bug and actually makes the code a bit tidier too.
The work is done in the new function
GHC.Core.Opt.OccurAnal.mkRhsOccEnv,
especially the bit that prepares the `occ_one_shots` for the RHS.
See Note [The OccEnv for a right hand side]
* When floating out a binding we must be conservative about one-shot
info. But we were zapping the entire demand info, whereas we only
really need zap the /top level/ cardinality.
See Note [Floatifying demand info when floating]
in GHC.Core.Opt.SetLevels
For some reason there is a 2.2% improvement in compile-time allocation
for CoOpt_Read. Otherwise nickels and dimes.

It used `getPackageIncludePath` which name doesn't convey that it looks

This patch extends the grammar of expressions with syntax that is
typically found only in types:
* function types (a -> b), (a ->. b), (a %m -> b)
* constrained types (ctx => t)
* forall-quantification (forall tvs. t)
The new forms are guarded behind the RequiredTypeArguments extension,
as specified in GHC Proposal #281. Examples:
{-# LANGUAGE RequiredTypeArguments #-}
e1 = f (Int -> String) -- function type
e2 = f (Int %1 -> String) -- linear function type
e3 = f (forall a. Bounded a => a) -- forall type, constraint
The GHC AST and the TH AST have been extended as follows:
syntax | HsExpr | TH.Exp
---------------+----------+--------------
a -> b | HsFunArr | ConE (->)
a %m -> b | HsFunArr | ConE FUN
ctx => t | HsQual | ConstrainedE
forall a. t | HsForAll | ForallE
forall a -> t | HsForAll | ForallVisE
Additionally, a new warning flag -Wview-pattern-signatures has been
introduced to aid with migration to the new precedence of (e -> p :: t).

This commit adds support for multiline strings, proposed at
https://github.com/ghc-proposals/ghc-proposals/pull/569.
Multiline strings can now be written as:
myString =
"""
this is a
multiline string
"""
The multiline string will have leading indentation stripped away.
Full details of this post-processing may be found at the new
GHC.Parser.String module.
In order to cleanly implement this and maximize reusability, I
broke out the lexing logic for strings out of Lexer.x into a
new GHC.Parser.String module, which lexes strings with any
provided "get next character" function. This also gave us the
opportunity to clean up this logic, and even optimize it a bit.
With this change, parsing string literals now takes 25% less
time and 25% less space.

The `mi_usages` field of the interface files must use a deterministic
list of `Usage`s to guarantee a deterministic interface. However, this
list was, in its origins, constructed from a `ModuleEnv` which uses a
non-deterministic ordering that was leaking into the interface.
Specifically, ImportedMods = ModuleEnv ... would get converted to a list and
then passed to `mkUsageInfo` to construct the Usages.
The solution is simple. Back `ImportedMods` with a deterministic map.
`Map Module ...` is enough, since the Ord instance for `Module` already
uses a stable, deterministic, comparison.

The main purpose is to create tests for minimal app (hello world and its variations, i.e. unicode used) distribution size metric.
Many platforms support distribution in compressed form via gzip. It would be nice to collect information on how much size is taken by the executional bundle for each platform at minimal edge case.
2 groups of tests are added:
1. We extend javascript backend size tests with gzip-enabled versions for all cases where an optimizing compiler is used (for now it is google closure compiler).
2. We add trivial hello world tests with gzip-enabled versions for all other platforms at CI pipeline where no external optimizing compiler is used.

- beef61351b240967b49169d27a9a19565cf3c4af enabled the use of
MO_Add/MO_Sub for 64-bit operations in the C and LLVM backends
- 6755d833af8c21bbad6585144b10e20ac4a0a1ab did the same for the x86 NCG
backend
However we store some literal values as `Int` in the compiler. As a
result, some Cmm optimizations transformed target 64-bit literals into
compiler `Int`. If the compiler is 32-bit, this leads to computing with
wrong literals (see #24893 and #24700).
This patch disables these Cmm optimizations for 32-bit compilers. This
is unsatisfying (optimizations shouldn't be compiler-word-size
dependent) but it fixes the bug and it makes the patch easy to backport.
A proper fix would be much more invasive but it shall be implemented in
the future.

other instances of this failure in #23013. My hunch is that they were

We build these two packages as regular boot library dependencies rather
than using the `in-ghc-tree` flag to include the source files into the haddock
executable.
The `in-ghc-tree` flag is moved into haddock-api to ensure that haddock built
from hackage can still find the location of the GHC bindist using `ghc-paths`.
Addresses #24834
This causes a metric decrease under non-release flavours because under these
flavours libraries are compiled with optimisation but executables are not.
Since we move the bulk of the code from the haddock executable to the
haddock-api library, we see a metric decrease on the validate flavours.

At GhcRn stage, in isIrrefutableHsPat we only looked up data constructors
in the RdrEnv, which meant that we lacked fallibility information for
out-of-scope constructors (which can arise from Template Haskell splices).
Instead, we use 'lookupGREInfo', which looks up the information in
the type environment. This was the correct function to call all along,
but was not used in 572fbc44 due to import cycle reasons. The appropriate
functions, 'irrefutableConLike{Rn,Tc}' have been moved to 'GHC.Rename.Env',
which avoids import cycles.

- Rename LoadedBCOs into LazyBCOs
- Bundle SptEntries with CompiledByteCode and removed [SptEntry] field

- Rename Linkable's LM constructor into Linkable: in the past we had LM
and LP for Module and Package, now we only have the former.
- Rename Unlinked into LinkablePart (and linkableUnlinked into
linkableParts)
- Use NonEmpty to encode invariant in Linkable's linkableParts type
- Add helpers: linkableLibs, linkableBCOs, etc.
- Add documentation
- Remove partial nameOfObject
- Rename nameOfObject_maybe into linkablePartPath
- Rename byteCodeOfObject into linkablePartAllBCOs.
- Refactor linkablePartAllBCOs to avoid a panic if a LazyBCO has a C
stub. Document the fact that LazyBCOs are returned in this case
(contrary to linkableBCOs which only returns non-lazy ones)
Refactoring done while trying to understand how to adapt the linker code
to support the JS backend too (cf #24886).

This squashed commit adds support for exportable named defaults, the accepted
GHC proposal at https://github.com/ghc-proposals/ghc-proposals/pull/409
The proposal extends the Haskell '98 declarations
default (Int, Double)
which were implicitly always applying to Num class alone, to allow specifying
an arbitrary single-parameter class:
default IsString (Text, String)
The effect of this declaration would be to eliminate the ambiguous type errors
around string literals when OverloadedStrings extension is active. The
declaration by itself has effect only in its module, so the proposal also adds
the ability to export class defaults:
module MyModule (default IsIstring)
Once the language extension is published and established, we can consider using
it in base and other libraries.
See Note [Named default declarations] in GHC.Tc.Gen.Default
for implementation details.

This MR revised the crucial kick-out criteria in the constraint solver.
Ticket #24984 showed an example in which
* We were kicking out unnecessarily
* That gave rise to extra work, of course
* But it /also/ led to exponentially-sized coercions due to lack
of sharing in coercions (something we want to fix separately #20264)
This MR sharpens up the kick-out criteria; specifially in (KK2) we look
only under type family applications if (fs>=fw).
This forced me to understand the existing kick-out story, and I ended
up rewriting many of the careful Notes in GHC.Tc.Solver.InertSet.
Especially look at the new `Note [The KickOut Criteria]`
The proof of termination is not air-tight, but it is better than before,
and both Richard and I think it's correct :-).

This patch removes the -fasm flag from test ways, except ways like
optasm that explicitly state they are meant to be compiled with NCG
backend. Most test ways should use the default codegen backend, and
the precense of -fasm can cause stderr mismatches like this when GHC
is configured with the unregisterised backend:
```

This commit fixes isMinTTY.h casing in isMinTTY.c that's compiled for
Windows targets. While this looks harmless given Windows filesystems
are case-insensitive by default, it does cause a compilation warning
with recent versions of clang, so we might as well fix the casing:
```

This data is used alongside Core bindings to reconstruct intermediate
build products when linking Template Haskell splices with bytecode.
Since foreign stubs and files are generated in the pipeline, they were
lost with only Core bindings stored in interfaces.
The interface codec type `IfaceForeign` contains a simplified
representation of `ForeignStubs` and the set of foreign sources that
were manually added by the user.
When the backend phase writes an interface, `mkFullIface` calls
`encodeIfaceForeign` to read foreign source file contents and assemble
`IfaceForeign`.
After the recompilation status check of an upstream module,
`initWholeCoreBindings` calls `decodeIfaceForeign` to restore
`ForeignStubs` and write the contents of foreign sources to the file
system as temporary files.
The restored foreign inputs are then processed by `hscInteractive` in
the same manner as in a regular pipeline.
When linking the stub objects for splices, they are excluded from suffix
adjustment for the interpreter way through a new flag in `Unlinked`.
For details about these processes, please consult Note [Foreign stubs
and TH bytecode linking].

We are producing bindists where the target triple is
aarch64-alpine-linux
when it should be
aarch64-unknown-linux
This is because the bootstrapped compiler originally set the target
triple to `aarch64-alpine-linux` which is when propagated forwards by
setting `bootstrap_target` from the bootstrap compiler target.
In order to break this chain we explicitly specify build/host/target for
aarch64-alpine.
This requires a new configure flag `--enable-ignore-` which just
switches off a validation check that the target platform of the
bootstrap compiler is the same as the build platform. It is the same,
but the name is just wrong.
These commits can be removed when the bootstrap compiler has the correct
target triple (I looked into patching this on ci-images, but it looked
hard to do correctly as the build/host platform is not in the settings
file).

This is a reinterpretation of GHC Proposal #409 that avoids a breaking
change introduced in fa0dbaca6c "Implements the Exportable Named Default proposal"
Consider a module M that has no explicit export list:
module M where
default (Rational)
Should it export the default (Rational)?
The proposal says "yes", and there's a test case for that:
default/DefaultImport04.hs
However, as it turns out, this change in behavior breaks existing
programs, e.g. the colour-2.3.6 package can no longer be compiled,
as reported in #25206.
In this patch, we make implicit exports of defaults conditional on
the NamedDefaults extension. This fix is unintrusive and compliant
with the existing proposal text (i.e. it does not require a proposal
amendment). Should the proposal be amended, we can go for a simpler
solution, such as requiring all defaults to be exported explicitly.
Test case: testsuite/tests/default/T25206.hs

The lazy structure (a list) in a strict field in `DmdType` is not fully

It seems there is likely still more work to be done here as it seems we
may be trading space usage for work done. For now, this is the right
choice as rather than using all the memory on my computer, compilation
just takes a little bit longer.

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.

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.

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.

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

to be attached an effect for error reporting in a later refactoring

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.

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]`.

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@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.

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.
