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
forced which leads to a very large thunk build-up.
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.

has already been evacuated. The previous logic was meant to print the
evacuated closure's type in the error message, but it was completely

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
reporting, and thus accept these lists at face value. They will have
to be attached an effect for error reporting in a later refactoring

There is one tricky aspect with wired-in packages where the boot package

situation of loading wired-in packages into the multi-repl seems like

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.

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.
