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.

RTS: declare setKeepCAFs symbol
Commit 08ba8720 failed to declare the dependency of keepCAFsForGHCi on
the symbol setKeepCAFs in the RTS, which led to undefined symbol errors
on Windows, as exhibited by the testcase frontend001.
Thanks to Moritz Angermann and Ryan Scott for the diagnosis and fix.

Fix shadowing lacuna in OccurAnal
Issue #22623 demonstrated another lacuna in the implementation
of wrinkle (BS3) in Note [The binder-swap substitution] in
the occurrence analyser.
I was failing to add TyVar lambda binders using
addInScope/addOneInScope and that led to a totally bogus binder-swap
transformation.
Very easy to fix.

Only gc sparks locally when we can ensure marking is done.
When performing GC without work stealing there was no guarantee that
spark pruning was happening after marking of the sparks. This could
cause us to GC live sparks under certain circumstances.

T10955: Set DYLD_LIBRARY_PATH for darwin
The correct path to direct the dynamic linker on darwin is
DYLD_LIBRARY_PATH rather than LD_LIBRARY_PATH. On recent versions of OSX
using LD_LIBRARY_PATH seems to have stopped working.

On recent versions of OSX, running `ulimit -v` results in
```

```
Time is too short to work out what random stuff Apple has been doing
with ulimit, so just skip the test like we do for other platforms.

Pass -Wl,-no_fixup_chains to ld64 when appropiate
Recent versions of MacOS use a version of ld where `-fixup_chains` is on by default.
This is incompatible with our usage of `-undefined dynamic_lookup`. Therefore we
explicitly disable `fixup-chains` by passing `-no_fixup_chains` to the linker on
darwin. This results in a warning of the form:
ld: warning: -undefined dynamic_lookup may not work with chained fixups
The manual explains the incompatible nature of these two flags:
-undefined treatment
Specifies how undefined symbols are to be treated. Options are: error, warning,
suppress, or dynamic_lookup. The default is error. Note: dynamic_lookup that
depends on lazy binding will not work with chained fixups.

Handle shadowing in DmdAnal (#22718)
Previously, when we had a shadowing situation like
```hs
f x = ... -- demand signature <1L><1L>
main = ... \f -> f 1 ...
```
we'd happily use the shadowed demand signature at the call site inside the
lambda. Of course, that's wrong and solution is simply to remove the demand
signature from the `AnalEnv` when we enter the lambda.
This patch does so for all binding constructs Core.
In #22718 the issue was caused by LetUp not shadowing away the existing demand
signature for the let binder in the let body. The resulting absent error is
fickle to reproduce; hence no reproduction test case. #17478 would help.
Fixes #22718.
It appears that TcPlugin_Rewrite regresses by ~40% on Darwin. It is likely that
DmdAnal was exploiting ill-scoped analysis results.

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.

nativeGen/X86: MFENCE is unnecessary for release semantics
In #22764 a user noticed that a program implementing a simple atomic
counter via an STRef regressed significantly due to the introduction of
necessary atomic operations in the MutVar# primops (#22468). This
regression was caused by a bug in the NCG, which emitted an unnecessary
MFENCE instruction for a release-ordered atomic write. MFENCE is rather
only needed to achieve sequentially consistent ordering.
Fixes #22764.

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.

that the size is a multiple of the alignment.

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.

enable `-split-sections` by default but want to disable it in certain

hadrian: Add no_split_sections tranformer
This transformer reverts the effect of `split_sections`, which we intend
to use for platforms which don't support split sections.
In order to achieve this we have to modify the implemntation of the
split_sections transformer to store whether we are enabling
split_sections directly in the `Flavour` definition. This is because
otherwise there's no convenient way to turn off split_sections due to
having to pass additional linker scripts when merging objects.

Fix recompilation checking for multiple home units
The key part of this change is to store a UnitId in the

* Fine-grained dependency tracking is used if the dependency comes from
any home unit.
* We actually look up the right module when checking whether we need to
recompile in the `UsageHomeModuleInterface` case.
These scenarios are both checked by the new tests (
multipleHomeUnits_recomp and multipleHomeUnits_recomp_th )

Use NodeKey rather than ModuleName in pruneCache

* In normal compilation, the same module name can appear for a file and it's boot file.

The fix is to use a `NodeKey` as the actual key for the interfaces which includes `ModuleName`, `IsBoot` and `UnitId`.

Improve driver diagnostic messages by including UnitId in message
Currently the driver diagnostics don't give any indication about which unit they correspond to.
For example `-Wmissing-home-modules` can fire multiple times for each different home unit and gives no indication about which unit it's actually reporting about.
Perhaps a longer term fix is to generalise the providence information away from a SrcSpan so that these kind of whole project errors can be reported with an accurate provenance. For now we can just include the `UnitId` in the error message.
Fixes #22678

Key ModSummary cache by UnitId as well as FilePath
Multiple units can refer to the same files without any problem. Just
another assumption which needs to be updated when we may have multiple
home units.
However, there is the invariant that within each unit each file only
maps to one module, so as long as we also key the cache by UnitId then
we are all good.
This led to some confusing behaviour in GHCi when reloading,
multipleHomeUnits_shared distils the essence of what can go wrong.

Finder: Look in current unit before looking in any home package dependencies
In order to preserve existing behaviour it's important to look within the current component before consideirng a module might come from an external component.
This already happened by accident in `downsweep`, (because roots are used to repopulated the cache) but in the `Finder` the logic was the wrong way around.
Fixes #22680

Add a missing checkEscapingKind
Ticket #22743 pointed out that there is a missing check,
for type-inferred bindings, that the inferred type doesn't
have an escaping kind.
The fix is easy.
