As observed in #22141, GHC was not doing its due diligence in catching code
that should require `DataKinds` in order to use. Most notably, it was allowing
the use of arbitrary data types in kind contexts without `DataKinds`, e.g.,
```hs
data Vector :: Nat -> Type -> Type where
```
This patch revamps how GHC tracks `DataKinds`. The full specification is
written out in the `DataKinds` section of the GHC User's Guide, and the
implementation thereof is described in `Note [Checking for DataKinds]` in
`GHC.Tc.Validity`. In brief:
* We catch _type_-level `DataKinds` violations in the renamer. See
`checkDataKinds` in `GHC.Rename.HsType` and `check_data_kinds` in
`GHC.Rename.Pat`.
* We catch _kind_-level `DataKinds` violations in the typechecker, as this
allows us to catch things that appear beneath type synonyms. (We do *not*
want to do this in type-level contexts, as it is perfectly fine for a type
synonym to mention something that requires DataKinds while still using the
type synonym in a module that doesn't enable DataKinds.) See `checkValidType`
in `GHC.Tc.Validity`.
* There is now a single `TcRnDataKindsError` that classifies all manner of
`DataKinds` violations, both in the renamer and the typechecker. The
`NoDataKindsDC` error has been removed, as it has been subsumed by
`TcRnDataKindsError`.
* I have added `CONSTRAINT` is `isKindTyCon`, which is what checks for illicit
uses of data types at the kind level without `DataKinds`. Previously,
`isKindTyCon` checked for `Constraint` but not `CONSTRAINT`. This is
inconsistent, given that both `Type` and `TYPE` were checked by `isKindTyCon`.
Moreover, it thwarted the implementation of the `DataKinds` check in
`checkValidType`, since we would expand `Constraint` (which was OK without
`DataKinds`) to `CONSTRAINT` (which was _not_ OK without `DataKinds`) and
reject it. Now both are allowed.
* I have added a flurry of additional test cases that test various corners of
`DataKinds` checking.
Fixes #22141.

at the same time, otherwise all the EPA tests break.

This allows original spacing to apply in most cases, only changed
AST items need initial delta positions.

* EPA Introduce HasTrailing in ExactPrint
Use [TrailingAnn] in enterAnn and remove it from
ExactPrint (LocatedN RdrName)
* In HsDo, put TrailingAnns at top of LastStmt
* EPA: do not convert comments to deltas when balancing.
* EPA: deal with fallout from getMonoBind

This patch implements the T2T (term-to-type) transformation in
expressions. Given a function with a required type argument
vfun :: forall a -> ...
the user can now call it as
vfun (Maybe Int)
instead of
vfun (type (Maybe Int))
The Maybe Int argument is parsed and renamed as a term (HsExpr), but then
undergoes a conversion to a type (HsType).
See the new function expr_to_type in compiler/GHC/Tc/Gen/App.hs
and Note [RequiredTypeArguments and the T2T mapping]

An Anchor has a location and an operation, which is either that it is
unchanged or that it has moved with a DeltaPos
data Anchor = Anchor { anchor :: RealSrcSpan
, anchor_op :: AnchorOperation }
An EpaLocation also has either a location or a DeltaPos
data EpaLocation = EpaSpan !RealSrcSpan !(Strict.Maybe BufSpan)
| EpaDelta !DeltaPos ![LEpaComment]
Now that we do not care about always having a location in the anchor,
we remove Anchor and replace it with EpaLocation
We do this with a type alias initially, to ease the transition.
The alias will be removed in time.
We also have helpers to reconstruct the AnchorOperation from an
EpaLocation. This is also temporary.

This flag isn't necessarily available to other linkers on darwin, so we must

A regression in the new iconv() distributed with XCode 15 and MacOS
Sonoma causes the test 'encoding004' to fail in the CP936 roundrip.
We mark this test as fragile until this is fixed upstream (rather than
broken, since previous versions of iconv pass the test)

MacOS seems to have fixed an issue where it used to ignore the variable

variable, we mark tests that were previously broken in spite of it as

In XCode 15's linker, -single_module is the default and otherwise
passing it as a flag results in a warning being raised:
ld: warning: -single_module is obsolete
This patch fixes this warning by, at configure time, determining whether
the linker supports -single_module (which is likely false for all
non-darwin linkers, and true for darwin linkers in previous versions of
macOS), and using that information at runtime to decide to pass or not
the flag in the invocation.
Fixes #24168

This commit fixes an issue with ModUnusable introduced in df0f148feae.
In mkUnusableModuleNameProvidersMap we traverse the list of unusable
units and generate ModUnusable origin for all the modules they contain:
exposed modules, hidden modules, and also re-exported modules. To do
this we have a two-level map:
ModuleName -> Unit:ModuleName (aka Module) -> ModuleOrigin
So for each module name "M" in broken unit "u" we have:
"M" -> u:M -> ModUnusable reason
However in the case of module reexports we were using the *target*
module as a key. E.g. if "u:M" is a reexport for "X" from unit "o":
"M" -> o:X -> ModUnusable reason
Case 1: suppose a reexport without module renaming (u:M -> o:M) from
unusable unit u:
"M" -> o:M -> ModUnusable reason
Here it's claiming that the import of M is unusable because a reexport
from u is unusable. But if unit o isn't unusable we could also have in
the map:
"M" -> o:M -> ModOrigin ...
Issue: the Semigroup instance of ModuleOrigin doesn't handle the case
(ModUnusable <> ModOrigin)
Case 2: similarly we could have 2 unusable units reexporting the same module
without renaming, say (u:M -> o:M) and (v:M -> o:M) with u and v
unusable. It gives:
"M" -> o:M -> ModUnusable ... (for u)
"M" -> o:M -> ModUnusable ... (for v)
Issue: the Semigroup instance of ModuleOrigin doesn't handle the case
(ModUnusable <> ModUnusable).
This led to #21097, #16996, #11050.
To fix this, in this commit we make ModUnusable track whether the module
used as key is a reexport or not (for better error messages) and we use
the re-export module as key. E.g. if "u:M" is a reexport for "o:X" and u
is unusable, we now record:
"M" -> u:M -> ModUnusable reason reexported=True
So now, we have two cases for a reexport u:M -> o:X:
- u unusable: "M" -> u:M -> ModUnusable ... reexported=True
- u usable: "M" -> o:X -> ModOrigin ... reexportedFrom=u:M
The second case is indexed with o:X because in this case the Semigroup
instance of ModOrigin is used to combine valid expositions of a module
(directly or via reexports).
Note that module lookup functions select usable modules first (those who
have a ModOrigin value), so it doesn't matter if we add new ModUnusable
entries in the map like this:
"M" -> {
u:M -> ModUnusable ... reexported=True
o:M -> ModOrigin ...
}
The ModOrigin one will be used. Only if there is no ModOrigin or
ModHidden entry will the ModUnusable error be printed. See T21097 for an
example printing several reasons why an import is unusable.

A `.target` file generated by ghc-toolchain or by configure can become
invalid if the target representation (`Toolchain.Target`) is changed
while the files are not re-generated by calling `./configure` or
`ghc-toolchain` again. There is also the issue of hadrian caching the
dependencies on `.target` files, which makes parsing fail when reading
reading the cached value if the representation has been updated.
This patch provides a better error message in both situations, moving
away from a terrible `Prelude.read: no parse` error that you would get
otherwise.

In Parser.y, the tup_tail rule had the following option

* Generalise the metric logic by adding an additional field which
allows you to specify how to query for the actual value. Previously
the method of querying the baseline value was abstracted (but always
set to the same thing).
* This requires rejigging how the stat collection works slightly but now
it's more uniform and hopefully simpler.
* Introduce some new "generic" helper functions for writing generic
stats tests.
- collect_size ( deviation, path )
Record the size of the file as a metric
- stat_from_file ( metric, deviation, path )
Read a value from the given path, and store that as a metric
- collect_generic_stat ( metric, deviation, get_stat)
Provide your own `get_stat` function, `lambda way: <Int>`, which
can be used to establish the current value of the metric.
- collect_generic_stats ( metric_info ):
Like collect_generic_stat but provide the whole dictionary of metric
definitions.
{ metric: {
deviation: <Int>
current: lambda way: <Int>
} }
* Introduce two new "size" metrics for keeping track of build products.
- `size_hello_obj` - The size of `hello.o` from compiling hello.hs
- `libdir` - The total size of the `libdir` folder.
* Track the number of modules in the AST tests
- CountDepsAst
- CountDepsParser
This lays the infrastructure for #24191 #22256 #17129

It only existed to wrap the original SrcSpan in a location, and
provide a place for the exact print annotation.

EpaLocation is used to position things. It has two constructors,
EpaSpan holding a SrcSpan, and EpaDelta with a delta position and a
possible list of comments. The comment list is needed because the
location in EpaDelta has no absolute information to decide which
comments should be emitted before them when printing.
But it is also used for specifying the position of a comment. To
prevent the absurdity of a comment position having a list of comments
in it, we make EpaLocation parameterisable, using comments for the
normal case and a constant for within comments.

This patch implements the T2T (term-to-type) transformation in patterns.
Patterns that are checked against a visible forall can now be written
without the `type` keyword:
\(type t) (x :: t) -> ... -- old
\t (x :: t) -> ... -- new
The `t` binder is parsed and renamed as a term pattern (Pat), but
then undergoes a conversion to a type pattern (HsTyPat).

Before, the source location would point at the surrounding function definition,
causing the confusion in #24234.
I also took the opportunity to introduce a new `LazyPatCtx :: HsMatchContext _`
to make the warning message say "irrefutable pattern" instead of "pattern
binding".

but it seems pointless to run the pipeline twice when `hscMaybeWriteIface` is already
designed to write both `hi` and `dyn_hi` files if dynamic-too is enabled.

* It improves the rule matcher to deal nicely with the case where
the rule does not quantify over coercion variables, but the the
template has a cast in it. See Note [Casts in the template]
