Added a new warning about compatibility with RequiredTypeArguments
This commit introduces a new warning
that indicates code incompatible with
future extension: RequiredTypeArguments.
Enabling this extension may break some code and the warning
will help to make it compatible in advance.

As noted in #22414, this file (which appears to be a benchmark for
characterising the one-step allocator's MBlock cache) is currently
unreferenced. Remove it.

Introduce the TypeAbstractions language flag
GHC Proposals #448 "Modern scoped type variables"
and #425 "Invisible binders in type declarations"
introduce a new language extension flag: TypeAbstractions.
Part of the functionality guarded by this flag has already been
implemented, namely type abstractions in constructor patterns, but it
was guarded by a combination of TypeApplications and ScopedTypeVariables
instead of a dedicated language extension flag.
This patch does the following:
* introduces a new language extension flag TypeAbstractions
* requires TypeAbstractions for @a-syntax in constructor patterns
instead of TypeApplications and ScopedTypeVariables
* creates a User's Guide page for TypeAbstractions and
moves the "Type Applications in Patterns" section there
To avoid a breaking change, the new flag is implied by
ScopedTypeVariables and is retroactively added to GHC2021.

Misc cleanup
- Remove unused mkWildEvBinder
- Use typeTypeOrConstraint - more symmetric and asserts that
that the type is Type or Constraint
- Fix escape sequences in Python; they raise a deprecation warning
with -Wdefault

Refactor the treatment of loopy superclass dicts
This patch completely re-engineers how we deal with loopy superclass
dictionaries in instance declarations. It fixes #20666 and #19690
The highlights are
* Recognise that the loopy-superclass business should use precisely
the Paterson conditions. This is much much nicer. See
Note [Recursive superclasses] in GHC.Tc.TyCl.Instance
* With that in mind, define "Paterson-smaller" in
Note [Paterson conditions] in GHC.Tc.Validity, and the new
data type `PatersonSize` in GHC.Tc.Utils.TcType, along with
functions to compute and compare PatsonSizes
* Use the new PatersonSize stuff when solving superclass constraints
See Note [Solving superclass constraints] in GHC.Tc.TyCl.Instance
* In GHC.Tc.Solver.Monad.lookupInInerts, add a missing call to
prohibitedSuperClassSolve. This was the original cause of #20666.
* Treat (TypeError "stuff") as having PatersonSize zero. See
Note [Paterson size for type family applications] in GHC.Tc.Utils.TcType.
* Treat the head of a Wanted quantified constraint in the same way
as the superclass of an instance decl; this is what fixes #19690.
See GHC.Tc.Solver.Canonical Note [Solving a Wanted forall-constraint]
(Thanks to Matthew Craven for this insight.)
This entailed refactoring the GivenSc constructor of CtOrigin a bit,
to say whether it comes from an instance decl or quantified constraint.
* Some refactoring way in which redundant constraints are reported; we
don't want to complain about the extra, apparently-redundant
constraints that we must add to an instance decl because of the
loopy-superclass thing. I moved some work from GHC.Tc.Errors to
GHC.Tc.Solver.
* Add a new section to the user manual to describe the loopy
superclass issue and what rules it follows.

Fix void-arg-adding mechanism for worker/wrapper
As #22725 shows, in worker/wrapper we must add the void argument
/last/, not first. See GHC.Core.Opt.WorkWrap.Utils
Note [Worker/wrapper needs to add void arg last].
That led me to to study GHC.Core.Opt.SpecConstr
Note [SpecConstr needs to add void args first] which suggests the
opposite! And indeed I think it's the other way round for SpecConstr
-- or more precisely the void arg must precede the "extra_bndrs".
That led me to some refactoring of GHC.Core.Opt.SpecConstr.calcSpecInfo.

configure: Fix escaping of `$tooldir`
In !9547 I introduced `$tooldir` directories into GHC's default link and
compilation flags to ensure that our C toolchain finds its own headers
and libraries before others on the system. However, the patch was subtly
wrong in the escaping of `$tooldir`. Fix this.
Fixes #22561.

Fix contification with stable unfoldings (#22428)
Many functions now return a `TailUsageDetails` that adorns a `UsageDetails` with
a `JoinArity` that reflects the number of join point binders around the body
for which the `UsageDetails` was computed. `TailUsageDetails` is now returned by
`occAnalLamTail` as well as `occAnalUnfolding` and `occAnalRules`.
I adjusted `Note [Join points and unfoldings/rules]` and
`Note [Adjusting right-hand sides]` to account for the new machinery.
I also wrote a new `Note [Join arity prediction based on joinRhsArity]`
and refer to it when we combine `TailUsageDetails` for a recursive RHS.
I also renamed
* `occAnalLam` to `occAnalLamTail`
* `adjustRhsUsage` to `adjustTailUsage`
* a few other less important functions
and properly documented the that each call of `occAnalLamTail` must pair up with
`adjustTailUsage`.
I removed `Note [Unfoldings and join points]` because it was redundant with
`Note [Occurrences in stable unfoldings]`.
While in town, I refactored `mkLoopBreakerNodes` so that it returns a condensed
`NodeDetails` called `SimpleNodeDetails`.
Fixes #22428.

This patch introduces a more general version of &%> that works

rel_eng: Add release engineering scripts into ghc tree
It is better to keep these scripts in the tree as they depend on the CI
configuration and so on. By keeping them in tree we can keep them
up-to-date as the CI config changes and also makes it easier to backport
changes to the release script between release branches in future.
The final motivation is that it makes generating GHCUp metadata
possible.

Add scripts to generate ghcup metadata on nightly and release pipelines
1. A python script in .gitlab/rel_eng/mk-ghcup-metadata which generates
suitable metadata for consumption by GHCUp for the relevant
pipelines.
- The script generates the metadata just as the ghcup maintainers
want, without taking into account platform/library combinations. It
is updated manually when the mapping changes.
- The script downloads the bindists which ghcup wants to distribute,
calculates the hash and generates the yaml in the correct structure.
- The script is documented in the .gitlab/rel_eng/mk-ghcup-metadata/README.mk file
1a. The script requires us to understand the mapping from platform ->
job. To choose the preferred bindist for each platform the
.gitlab/gen_ci.hs script is modified to allow outputting a metadata
file which answers the question about which job produces the
bindist which we want to distribute to users for a specific
platform.
2. Pipelines to run on nightly and release jobs to generate metadata
- ghcup-metadata-nightly: Generates metadata which points directly to
artifacts in the nightly job.
- ghcup-metadata-release: Generates metadata suitable for inclusion
directly in ghcup by pointing to the downloads folder where the
bindist will be uploaded to.
2a. Trigger jobs which test the generated metadata in the downstream
`ghccup-ci` repo. See that repo for documentation about what is
tested and how but essentially we test in a variety of clean images
that ghcup can download and install the bindists we say exist in our
metadata.

testsuite: req_smp --> req_target_smp, req_ghc_smp
See #22630 and !9552
This commit:
- splits req_smp into req_target_smp and req_ghc_smp
- changes the testsuite driver to calculate req_ghc_smp
- changes a handful of tests to use req_target_smp instead of req_smp
- changes a handful of tests to use req_host_smp when needed
The problem:
- the problem this solves is the ambiguity surrounding req_smp
- on master req_smp was used to express the constraint that the program
being compiled supports smp _and_ that the host RTS (i.e., the RTS used
to compile the program) supported smp. Normally that is fine, but in
cross compilation this is not always the case as was discovered in #22630.
The solution:
- Differentiate the two constraints:
- use req_target_smp to say the RTS the compiled program is linked
with (and the platform) supports smp
- use req_host_smp to say the RTS the host is linked with supports smp
WIP: fix req_smp (target vs ghc)
add flag to separate bootstrapper
split req_smp -> req_target_smp and req_ghc_smp
update tests smp flags
cleanup and add some docstrings
only set ghc_with_smp to bootstrapper on S1 or CC
Only set ghc_with_smp to bootstrapperWithSMP of when testing stage 1
and cross compiling
test the RTS in config/ghc not hadrian
re-add ghc_with_smp
fix and align req names
fix T11760 to use req_host_smp
test the rts directly, avoid python 3.5 limitation
test the compiler in a try block
align out of tree and in tree withSMP flags
mark failing tests as host req smp
testsuite: req_host_smp --> req_ghc_smp
Fix ghc vs host, fix ghc_with_smp leftover

Bump ghc-tarballs to fix #22497
It turns out that gmp 6.2.1 uses the platform-reserved `x18` register on
AArch64/Darwin. This was fixed in upstream changeset 18164:5f32dbc41afc,
which was merged in 2020. Here I backport this patch although I do hope
that a new release is forthcoming soon.
Bumps gmp-tarballs submodule.
Fixes #22497.

Add PrimCallConv support to GHCi
This adds support for calling Cmm code from bytecode using the native
calling convention, allowing modules that use `foreign import prim`
to be loaded and debugged in GHCi.
This patch introduces a new `PRIMCALL` bytecode instruction and
a helper stack frame `stg_primcall`. The code is based on the
existing functionality for dealing with unboxed tuples in bytecode,
which has been generalised to handle arbitrary calls.
Fixes #22051

Refactor warning flag parsing to add missing flags
This adds `-Werror=<group>` and `-fwarn-<group>` flags for warning
groups as well as individual warnings. Previously these were defined
on an ad hoc basis so for example we had `-Werror=compat` but not
`-Werror=unused-binds`, whereas we had `-fwarn-unused-binds` but not
`-fwarn-compat`. Fixes #22182.

Give the RTS it's own configure script
Currently it doesn't do much anything, we are just trying to introduce
it without breaking the build. Later, we will move functionality from
the top-level configure script over to it.
We need to bump Cabal for https://github.com/haskell/cabal/pull/8649; to
facilitate and existing hack of skipping some configure checks for the
RTS we now need to skip just *part* not *all* of the "post configure"
hook, as running the configure script (which we definitely want to do)
is also implemented as part of the "post configure" hook. But doing this
requires exposing functionality that wasn't exposed before.

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 printing of promoted MkSolo datacon (#22785)
Problem: In 2463df2f, the Solo data constructor was renamed to MkSolo,
and Solo was turned into a pattern synonym for backwards compatibility.
Since pattern synonyms can not be promoted, the old code that pretty-printed
promoted single-element tuples started producing ill-typed code:
t :: Proxy ('Solo Int)
This fails with "Pattern synonym ‘Solo’ used as a type"
The solution is to track the distinction between type constructors and data
constructors more carefully when printing single-element tuples.

Fix recompilation checking for multiple home units
The key part of this change is to store a UnitId in the
`UsageHomeModule` and `UsageHomeModuleInterface`.
* 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
The `pruneCache` function assumes that the list of `CachedInfo` all have unique `ModuleName`, this is not true:
* In normal compilation, the same module name can appear for a file and it's boot file.
* In multiple home unit compilation the same ModuleName can appear in different units
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.

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.

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.

Fix Lint check for duplicate external names
Lint was checking for duplicate external names by calling removeDups,
which needs a comparison function that is passed to Data.List.sortBy.
But the comparison was not a valid ordering - it returned LT
if one of the names was not external.
For example, the previous implementation won't find a duplicate in
[M.x, y, M.x].
Instead, we filter out non-external names before looking for duplicates.

CmmToC: fix CmmRegOff for 64-bit register on a 32-bit target
We used to print the offset value to a platform word sized integer.
This is incorrect when the offset is negative (e.g. output of cmm
constant folding) and the register is 64-bit but on a 32-bit target,
and may lead to incorrect runtime result (e.g. #22607).
The fix is simple: just treat it as a proper MO_Add, with the correct
width info inferred from the register itself.
