In the `StgRhsCon` case of `GHC.Stg.Debug.collectStgRhs`, we were not coming up
with an initial source span based on the span of the binder, which was causing
instance dictionaries without dynamic superclass constraints to not have source
locations in their IPE info. Now they do.

In the ./configure script, if you pass the `LD` variable then this has
the effect of stopping use searching for a linker and hence passing
`-fuse-ld=...`.
We want to emulate this logic in ghc-toolchain, if a use explicilty
specifies `LD` variable then don't add `-fuse-ld=..` with the goal of
making ./configure and ghc-toolchain agree on which flags to use when
using the C compiler as a linker.
This is quite unsavoury as we don't bake the choice of LD into the
configuration anywhere but what's important for now is making
ghc-toolchain and ./configure agree as much as possible.

There are situations where the C compiler doesn't accept `--target` but

We were attempting to use the C compiler, as a linker, to compile a file
in the nopie check, but that won't work in general as the flags we pass
to the linker might not be compatible with the ones we pass when using
the C compiler.

`-no-pie` is a flag we pass when using the C compiler as a linker (see

As noted in `Note [Don't pass --target to emscripten toolchain]`,
emscripten's `emcc` is rather inconsistent with respect to its treatment
of the `--target` flag. Avoid this by special-casing this toolchain
in the `configure` script and `ghc-toolchain`.

See the recent discussion in !10360 --- Cabal will itself check for the
library for the packages that need it, and while the autoconf check
additionally does some other things like define a `HAS_LIBMINGWEX` C
Preprocessor macro, those other things are also unused and unneeded.
Progress towards #17191, which aims to get rid of `/configure` entirely.

We should resonably be able to expect that we won't exceed the number of
sections if we assume to be dealing with legal object files. We can however
not guarantee that we get some negative values, and while we try to
special case most, we should exclude negative indexing into the sections
array.
We also need to ensure that we do not try to derefences targetSection,
if it is NULL, due to the switch statement.

This change ensure that the reg + offset computation is always of the

add a 32bit offset (on 32bit platforms). This not only would fail type
sanity checking, but also incorrectly truncate 64bit values into 32bit
values silently on 32bit architectures.

`rts` and `ghc-prim` now no longer have a `*.cabal.in` to set Cabal flag
defaults; instead manual choices are passed to configure in the usual
way.
The old way was fundamentally broken, because it meant we were baking
these Cabal files for a specific stage. Now we only do stage-agnostic
@...@ substitution in cabal files (the GHC version), and so all
stage-specific configuration is properly confined to `_build` and the
right stage dir.
Also `include-ghc-prim` is a flag that no longer exists for `ghc-prim`
(it was removed in 835d8ddbbfb11796ea8a03d1806b7cee38ba17a6) so I got
rid of it.

A drastically improved architecture for local floating in CorePrep
that decouples the decision of whether a float is going to be let- or case-bound
from how far it can float (out of strict contexts, out of lazy contexts, to
top-level).
There are a couple of new Notes describing the effort:
* `Note [Floating in CorePrep]` for the overview
* `Note [BindInfo and FloatInfo]` for the new classification of floats
* `Note [Floats and FloatDecision]` for how FloatInfo is used to inform
floating decisions
This is necessary ground work for proper treatment of Strict fields and
unlifted values at top-level.
Fixes #23442.

This completes a5227080b57cb51ac34d4c9de1accdf6360b818b, the
`ghc-usage.txt` and `ghci-usage.txt` file are also used by the `ghc`
library so need to make sure they are present in the libdir even if we
are not going to build `ghc-bin`.
This also fixes things for cross compilers because the stage2
cross-compiler requires the ghc-usage.txt file, but we are using
the stage2 lib folder but not building stage3:exe:ghc-bin so
ghc-usage.txt was not being generated.

In `GHC.Rename.Names.mkImportOccEnv`, we sometimes discard one import
item in favour of another, as explained in Note [Dealing with imports]
in `GHC.Rename.Names`. However, this can cause us to lose track of
important parent information.
Consider for example #24084:
module M1 where { class C a where { type T a } }
module M2 ( module M1 ) where { import M1 }
module M3 where { import M2 ( C, T ); instance C () where T () = () }
When processing the import list of `M3`, we start off (for reasons that
are not relevant right now) with two `Avail`s attached to `T`, namely
`C(C, T)` and `T(T)`. We combine them in the `combine` function of
`mkImportOccEnv`; as described in Note [Dealing with imports] we discard
`C(C, T)` in favour of `T(T)`. However, in doing so, we **must not**
discard the information want that `C` is the parent of `T`. Indeed,
losing track of this information can cause errors when importing,
as we could get an error of the form
‘T’ is not a (visible) associated type of class ‘C’
We fix this by combining the two GREs for `T` using `plusGRE`.
Fixes #24084

Fix this error by passing -DNOSMP to CC as well.

Fixes #24091
Progress on #23966
Issue #24091 reports that `@ProjectVersion@` is no longer being
substituted in the GHC user's guide. I assume this is a recent issue,
but I am not sure how it's worked since
c1a3ecde720b3bddc2c8616daaa06ee324e602ab; it looks like both Hadrian and
configure are trying to substitute the same `.in` file!
Now only Hadrian does. That is better anyways; already something that
issue #23966 requested.
It seems like we were missing some dependencies in Hadrian. (I really,
really hate that this is possible!) Hopefully it is fixed now.

We used to have MIN_UPD_SIZE macro that describes the minimum reserved
size for thunks, so that the thunk can be overwritten in place as
indirections or blackholes. However, this macro has not been actually
defined or used anywhere since a long time ago; StgThunkHeader already
reserves a padding word for this purpose. Hence this patch which drops
stale mentions of MIN_UPD_SIZE.

ghc-api tests for wasm32 are more likely to timeout due to the large
wasm module sizes, especially when testing with wasm native tail
calls, given wasmtime's handling of tail call opcodes are suboptimal
at the moment. It makes sense to increase timeout specifically for
these tests on wasm32. This doesn't affect other targets, and for
wasm32 we don't increase timeout for all tests, so not to risk letting
major performance regressions slip through the testsuite.

48e391952c17ff7eab10b0b1456e3f2a2af28a9b
introduced `SYM_TYPE_DUP_DISCARD` to the bitfield.
The linker however, failed to mask the `SYM_TYPE_DUP_DISCARD` value.
Thus `== SYM_TYPE_CODE` comparisons easily failed. This lead to us
relocating DATA lookups (GOT) into E8 (call) and E9 (jump) instructions.

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.

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]

Closes #20532. This implements CLC proposal 104:
https://github.com/haskell/core-libraries-committee/issues/104
The design is explained in Note [DataToTag overview]
in GHC.Tc.Instance.Class. This replaces the existing
`dataToTag#` primop.
These metric changes are not "real"; they represent Unique-related
flukes triggering on a different set of jobs than they did previously.

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.

XCode 15 introduced a new linker which warns on duplicate libraries being

suggested by Brad King in CMake issue #25297.
This flag isn't necessarily available to other linkers on darwin, so we must
only configure it into the CC linker arguments if valid.

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.

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

Once this works through PostProcess.hs, it means we add an extra

Change the annotation type to a Bool to indicate this, and use the
EpAnn Anchor for the print location for the others.

* 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

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).

This patch does two things, to fix #23209:
* It improves SpecConstr so that it no longer quantifies over
coercion variables. See Note [SpecConstr and casts]
* 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]

For expediency, the initial implementation of linear types in GHC
made it so that let and where binders would always be considered
unrestricted. This was rather unpleasant, and probably a big obstacle
to adoption. At any rate, this was not how the proposal was designed.
This patch fixes this infelicity. It was surprisingly difficult to
build, which explains, in part, why it took so long to materialise.
As of this patch, let or where bindings marked with %1 will be
linear (respectively %p for an arbitrary multiplicity p). Unmarked let
will infer their multiplicity.
Here is a prototypical example of program that used to be rejected and
is accepted with this patch:
```haskell
f :: A %1 -> B
g :: B %1 -> C
h :: A %1 -> C
h x = g y
where
y = f x
```
Exceptions:
- Recursive let are unrestricted, as there isn't a clear semantics of
what a linear recursive binding would be.
- Destructive lets with lazy bindings are unrestricted, as their
desugaring isn't linear (see also #23461).
- (Strict) destructive lets with inferred polymorphic type are
unrestricted. Because the desugaring isn't linear (See #18461
down-thread).

Apparently the check was essentially always (as far as I can trace back: d0d47ba76f8f0501cf3c4966bc83966ab38cac27),
and while it does catch some mismatches, the type-checker will catch
them too. OTOH, it prevents writing completely reasonable programs.

XCODE_VERSION calls out to `xcodebuild`, which is only available
when having `Xcode` installed. The CommandLineTools are not
sufficient. To install Xcode, you must have an apple id to download
the Xcode.xip from apple.
We do not use xcodebuild anywhere in our build explicilty. At best
it appears to be a proxy for checking the linker or the compiler.
These should rather be done with
```
xcrun ld -version
```
or similar, and not by proxy through Xcode. The CLR should be
sufficient for building software on macOS.

Previously we attempted to ensure soundness of concurrent thunk update
by synchronizing on the access of the thunk's info table pointer field.
This was believed to be sufficient since the indirectee (which may
expose a closure allocated by another core) would not be examined
until the info table pointer update is complete.
However, it turns out that this can result in data races in the presence
of multiple threads racing a update a single thunk. For instance,
consider this interleaving under the old scheme:
Thread A Thread B
--------- ---------
t=0 Enter t
1 Push update frame
2 Begin evaluation
4 Pause thread
5 t.indirectee=tso
6 Release t.info=BLACKHOLE
7 ... (e.g. GC)
8 Resume thread
9 Finish evaluation
10 Relaxed t.indirectee=x
11 Load t.info
12 Acquire fence
13 Inspect t.indirectee
14 Release t.info=BLACKHOLE
Here Thread A enters thunk `t` but is soon paused, resulting in `t`
being lazily blackholed at t=6. Then, at t=10 Thread A finishes
evaluation and updates `t.indirectee` with a relaxed store.
Meanwhile, Thread B enters the blackhole. Under the old scheme this
would introduce an acquire-fence but this would only synchronize with
Thread A at t=6. Consequently, the result of the evaluation, `x`, is not
visible to Thread B, introducing a data race.
We fix this by treating the `indirectee` field as we do all other
mutable fields. This means we must always access this field with
acquire-loads and release-stores.
See #23185.

In the end the bindist creation logic copies them all into the bin
folder. There is no benefit to building a specific few binaries in the

This also removes the ad-hoc logic to copy the touchy and unlit
executables from stage0 into stage1. It takes <1s to build so we might
as well just build it.

Previously the remaining use of the C implementation on 32-bit platforms
resulted in a subtle bug, #24261. This was due to the C object (which
used the RTS's `atomic_inc64` macro) being compiled without `-threaded`
yet later being used in a threaded compiler.
Side-step this issue by using the pure Haskell `genSym` implementation on
all platforms. This required implementing `fetchAddWord64Addr#` in terms
of CAS on 64-bit platforms.

StgConApp stored a list of types. This list was used exclusively
during unarisation of unboxed sums (mkUbxSum).
However, this is at a wrong level of abstraction:
STG shouldn't be concerned with Haskell types, only PrimReps.
Update the code to store a [[PrimRep]]. Also, there's no point in storing
this list when we're not dealing with an unboxed sum.

Earlier, we used to pass all preprocessor flags to the c++ compiler.
This meant that -DPROFILING was passed to the c++ compiler because
it was a part of C++ flags
However, this was incorrect and the behaviour was changed in
8ff3134ed4aa323b0199ad683f72165e51a59ab6. See #21291.
But that commit exposed this bug where -DPROFILING was no longer being passed
when compiling c++ sources.
The fix is to explicitly include -DPROFILING in `opt_cxx` when profiling is
enabled to ensure we pass the correct options for the way to both C and C++
compilers

In #24296, we had a program in which we eta expanded away an error despite the
presence of `-fpedantic-bottoms`.
This was caused by turning called *at least once* lambdas into one-shot lambdas,
while with `-fpedantic-bottoms` it is only sound to eta expand over lambdas that
are called *exactly* once.
An example can be found in `Note [Combining arity type with demand info]`.
Fixes #24296.

This MR makes three improvements to SpecConstr: see #24282
* It fixes an outright (and recently-introduced) bug in `betterPat`, which
was wrongly forgetting to compare the lengths of the argument lists.
* It enhances ConVal to inclue a boolean for work-free-ness, so that the
envt can contain non-work-free constructor applications, so that we
can do more: see Note [ConVal work-free-ness]
* It rejigs `subsumePats` so that it doesn't reverse the list. This can
make a difference because, when patterns overlap, we arbitrarily pick
the first. There is no "right" way, but this retains the old
pre-subsumePats behaviour, thereby "fixing" the regression in #24282.

The comment claims that `simpleUserHooks` decrease verbosity, and it
does, but only for the `postConf` phase. The other phases are too
verbose with `-V`.
At the moment > 5000 lines of the build log are devoted to output from
`cabal copy`.
So I take the simple approach and just decrease the verbosity level
again.
If the output of `postConf` is essential then it would be better to
implement our own `UserHooks` which doesn't decrease the verbosity for
`postConf`.
Fixes #24338

Each phase of the simplifier typically rewrites the majority of ModGuts,
so we want to be able to release the old ModGuts as soon as possible.
`name_ppr_ctxt` lives throught the whole optimiser phase and it was
retaining a reference to `ModGuts`, so we were failing to release the
old `ModGuts` until the end of the phase (potentially doubling peak
memory usage for that particular phase).
This was discovered using eras profiling (#24332)
Fixes #24328

On posix platforms, when performing read/write on FDs, we check the
nonblocking flag first. For FDs without this flag (e.g. stdout), we
call fdReady() first, which in turn calls poll() to wait for I/O to be
available on that FD. This is problematic for wasm32-wasi: although
select()/poll() is supported via the poll_oneoff() wasi syscall, that
syscall is rather heavyweight and runtime behavior differs in
different wasi implementations. The issue is even worse when targeting
browsers, given there's no satisfactory way to implement async I/O as
a synchronous syscall, so existing JS polyfills for wasi often give up
and simply return ENOSYS.
Before we have a proper I/O manager that avoids poll_oneoff() for
async I/O on wasm, this patch improves the status quo a lot by merely
pretending all FDs are "nonblocking". Read/write on FDs will directly
invoke read()/write(), which are much more reliably handled in
existing wasi implementations, especially those in browsers.
