Refactor uses of `partitionEithers . map`
This patch changes occurences of the idiom
`partitionEithers (map f xs)` by the simpler form
`partitionWith f xs` where `partitionWith` is the utility function
defined in `GHC.Utils.Misc`.

Refactor: introduce stgArgRep
The function 'stgArgType' returns the type in STG. But this violates
the abstraction: in STG we're supposed to operate on PrimReps.
This introduces
stgArgRep ty = typePrimRep (stgArgType ty)
stgArgRep1 ty = typePrimRep1 (stgArgType ty)
stgArgRep_maybe ty = typePrimRep_maybe (stgArgType ty)
stgArgType is still directly used for unboxed tuples (should be fixable), FFI
and in ticky.

lint-codes: add new modes of operation

lint-codes: add Hadrian targets
This commit adds new Hadrian targets:
codes, codes:used - list all used diagnostic codes
codes:outdated - list outdated diagnostic codes
This allows users to easily query GHC for used and outdated
diagnostic codes, e.g.
hadrian/build -j --flavour=<..> codes
will list all used diagnostic codes in the command line by running
the lint-codes utility in the "list codes" mode of operation.
The diagnostic code consistency and coverage test is still run as usual,
through the testsuite:
hadrian/build test --only="codes"

Fix several mistakes around free variables in iface breakpoints
Fixes #23612 , #23607, #23998 and #23666.
MR: !11026
The fingerprinting logic in `Iface.Recomp` failed lookups when processing decls containing breakpoints for two reasons:
* IfaceBreakpoint created binders for free variables instead of expressions
* When collecting free names for the dependency analysis for fingerprinting, breakpoint FVs were skipped

Refactor to combine HsLam and HsLamCase
This MR is pure refactoring (#23916):
* Combine `HsLam` and `HsLamCase`
* Combine `HsCmdLam` and `HsCmdLamCase`
This just arranges to treat uniformly
\x -> e
\case pi -> ei
\cases pis -> ie
In the exising code base the first is treated differently
to the latter two.
No change in behaviour.
More specifics:
* Combine `HsLam` and `HsLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsExpr`) into one data construtor covering
* Lambda
* `\case`
* `\cases`
* The new `HsLam` has an argument of type `HsLamVariant` to distinguish the three cases.
* Similarly, combine `HsCmdLam` and `HsCmdLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsCmd` ) into one.
* Similarly, combine `mkHsLamPV` and `mkHsLamCasePV` (methods of class `DisambECP`) into one. (Thank you Alan Zimmerman.)
* Similarly, combine `LambdaExpr` and `LamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsMatchContext`) into one: `LamAlt` with a `HsLamVariant` argument.
* Similarly, combine `KappaExpr` and `ArrowLamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsArrowMatchContext`) into one: `ArrowLamAlt` with a `HsLamVariant` argument.
* Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one.
* Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one.
* In the same `PsError` data type, combine `PsErrLambdaCmdInFunAppCmd` and `PsErrLambdaCaseCmdInFunAppCmd` into one.
* In the same `PsError` data tpye, combine `PsErrLambdaInFunAppExpr` and `PsErrLambdaCaseInFunAppExpr` into one.
p* Smilarly combine `ExpectedFunTyLam` and `ExpectedFunTyLamCase` (constructors of `GHC.Tc.Types.Origin.ExpectedFunTyOrigin`) into one.
Phew!

EPA: Replace Monoid with NoAnn
We currently use the Monoid class as a constraint on Exact Print
Annotation functions, so we can use mempty. But this leads to
requiring Semigroup instances too, which do not always make sense.
Instead, introduce a class NoAnn, with a function noAnn analogous to
mempty.

configure: Fix #21712 again
This is a bit of a shot in the dark to fix #24033, which appears to be
another instance of #21712. For some reason the ld-override logic
*still* appears to be active on Darwin targets (or at least one).
Consequently, on misconfigured systems we may choose a non-`ld64`
linker.
It's a bit unclear exactly what happened in #24033 but ultimately the
check added for #21712 was not quite right, checking for the
`ghc_host_os` (the value of which depends upon the bootstrap compiler)
instead of the target platform. Fix this.
Fixes #24033.

Revert "Pass preprocessor options to C compiler when building foreign C files (#16737)"
This reverts commit 1c18d3b41f897f34a93669edaebe6069f319f9e2.
`-optP` should pass options to the preprocessor, that might be a very
different program to the C compiler, so passing the options to the C
compiler is likely to result in `-optP` being useless.

Ensure unconstrained instance dictionaries get IPE info
In the `StgRhsCon` case of `GHC.Stg.Debug.collectStgRhs`, we were not coming up

locations in their IPE info. Now they do.

Add same LD hack to ghc-toolchain
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.
See #23857 for more discussion

Check for --target linker flag separately to C compiler
There are situations where the C compiler doesn't accept `--target` but

--target but when used as a linker it does.

Aarch ncg: Optimize immediate use for address calculations
When the offset doesn't fit into the immediate we now just reuse the
general getRegister' code path which is well optimized to compute the
offset into a register instead of a special case for CmmRegOff.
This means we generate a lot less code under certain conditions which is
why performance metrics for these improve.

RTS configure: Move over mem management checks
These are for heap allocation, a strictly RTS concern.
All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.
The RTS configure one has a new
```
AC_CHECK_SIZEOF([void *])
```
that the top-level configure version didn't have, so that
`ac_cv_sizeof_void_p` is defined. Once more code is moved over in latter
commits, that can go away.

Do not check for the `mingwex` library in `/configure`
See the recent discussion in !10360 --- Cabal will itself check for the

Preprocessor macro, those other things are also unused and unneeded.

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.

Do not substitute `@...@` for stage-specific values in cabal files
`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.

CorePrep: Refactor FloatingBind (#23442)
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.

hadrian: Move ghcBinDeps into ghcLibDeps
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.

Combine GREs when combining in mkImportOccEnv
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

Fixes #24091
Progress on #23966
Issue #24091 reports that `@ProjectVersion@` is no longer being

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.

testsuite: increase timeout of ghc-api tests for wasm32
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.

[PEi386] Mask SYM_TYPE_DUP_DISCARD in makeSymbolExtra
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.

More robust checking for DataKinds
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.

T2T in Expressions (#23738)
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]

EPA: Replace Anchor with EpaLocation
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.

darwin: Fix single_module is obsolete warning
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.

Fix unusable units and module reexport interaction (#21097)
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.

Improve error message when reading invalid `.target` files
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.

EPA: empty tup_tail has noAnn
In Parser.y, the tup_tail rule had the following option
| {- empty -} %shift { return [Left noAnn] }
Once this works through PostProcess.hs, it means we add an extra
Missing constructor if the last item was a comma.
Change the annotation type to a Bool to indicate this, and use the
EpAnn Anchor for the print location for the others.

Fix FMA primops generating broken assembly on x86.
`genFMA3Code` assumed that we had to take extra precations to avoid overwriting
the result of `getNonClobberedReg`. One of these special cases caused a bug resulting
in broken assembly.
I believe we don't need to hadle these cases specially at all, which means this MR simply
deletes the special cases to fix the bug.

Term variable capture (#23740)
This patch changes type variable lookup rules (lookupTypeOccRn) and
implicit quantification rules (filterInScope) so that variables bound
in the term namespace can be captured at the type level
{-# LANGUAGE RequiredTypeArguments #-}
f1 x = g1 @x -- `x` used in a type application
f2 x = g2 (undefined :: x) -- `x` used in a type annotation
f3 x = g3 (type x) -- `x` used in an embedded type
f4 x = ...
where g4 :: x -> x -- `x` used in a type signature
g4 = ...
This change alone does not allow us to accept examples shown above,
but at least it gets them past the renamer.

testsuite: Add mechanism to collect generic metrics
* 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

EPA: EpaDelta for comment has no comments
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.

T2T in Patterns (#23739)
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).

LinearTypes => MonoLocalBinds
- - - - -
8e0446df by Arnaud Spiwack at 2023-12-11T15:44:28+01:00
Linear let and where bindings
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

- 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

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.

Drop hard Xcode dependency
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.

Fix thunk update ordering
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.

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

genSym: Reimplement via CAS on 32-bit platforms
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.

Refactor: store [[PrimRep]] rather than [Type] in STG
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.

driver: Set -DPROFILING when compiling C++ sources with profiling
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

Arity: Require called *exactly once* for eta exp with -fpedantic-bottoms (#24296)
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]`.

Improve SpecConstr (esp nofib/spectral/ansi)
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.

hadrian: Reduce Cabal verbosity
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`.

Stop retaining old ModGuts throughout subsequent simplifier phases
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)

base: treat all FDs as "nonblocking" on wasm
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.

we implement these by flipping signs of some arguments

Fix irrelevant dodgy-foreign-imports warning on import f-pointers by value
A test *сс018* is attached (not sure about the naming convention though).
Note that without the fix, the test fails with the *dodgy-foreign-imports*
warning passed to stderr. The warning disappears after the fix.
GHC shouldn't warn on imports of natural function pointers from C by value
(which is feasible with CApiFFI), such as
```haskell
foreign import capi "cc018.h value f" f :: FunPtr (Int -> IO ())
```
where
```c
void (*f)(int);
```
See a related real-world use-case
[here](https://gitlab.com/daniel-casanueva/pcre-light/-/merge_requests/17).
There, GHC warns on import of C function pointer `pcre_free`.

Namespacing for WARNING/DEPRECATED pragmas (#24396)
New syntax for WARNING and DEPRECATED pragmas was added,
namely namespace specifierss:
namespace_spec ::= 'type' | 'data' | {- empty -}
warning ::= warning_category namespace_spec namelist strings
deprecation ::= namespace_spec namelist strings
A new data type was introduced to represent these namespace specifiers:
data NamespaceSpecifier =
NoSpecifier |
TypeNamespaceSpecifier (EpToken "type") |
DataNamespaceSpecifier (EpToken "data")
Extension field XWarning now contains this NamespaceSpecifier.
lookupBindGroupOcc function was changed: it now takes NamespaceSpecifier
and checks that the namespace of the found names matches the passed flag.
With this change {-# WARNING data D "..." #-} pragma will only affect value
namespace and {-# WARNING type D "..." #-} will only affect type
namespace. The same logic is applicable to DEPRECATED pragmas.
Finding duplicated warnings inside rnSrcWarnDecls now takes into
consideration NamespaceSpecifier flag to allow warnings with the
same names that refer to different namespaces.

Bump bytestring submodule to something closer to 0.12.1
...mostly so that 16d6b7e835ffdcf9b894e79f933dd52348dedd0c
(which reworks unaligned writes in Builder) and the stuff in
https://github.com/haskell/bytestring/pull/631 can see wider testing.
The less-terrible code for unaligned writes used in Builder on
hosts not known to be ulaigned-friendly also takes less effort
for GHC to compile, resulting in a metric decrease for T21839c
on some platforms.
The metric increase on T21839r is caused by the unrelated commit
750dac33465e7b59100698a330b44de7049a345c. It perhaps warrants
further analysis and discussion (see #23822) but is not critical.

Expand `do` blocks right before typechecking using the `HsExpansion` philosophy.
- Fixes #18324 #20020 #23147 #22788 #15598 #22086 #21206
- The change is detailed in
- Note [Expanding HsDo with HsExpansion] in `GHC.Tc.Gen.Do`
- Note [Doing HsExpansion in the Renamer vs Typechecker] in `GHC.Rename.Expr`
expains the rational of doing expansions in type checker as opposed to in the renamer
- Adds new datatypes:
- `GHC.Hs.Expr.XXExprGhcRn`: new datatype makes this expansion work easier
1. Expansion bits for Expressions, Statements and Patterns in (`ExpandedThingRn`)
2. `PopErrCtxt` a special GhcRn Phase only artifcat to pop the previous error message in the error context stack
- `GHC.Basic.Origin` now tracks the reason for expansion in case of Generated
This is useful for type checking cf. `GHC.Tc.Gen.Expr.tcExpr` case for `HsLam`
- Kills `HsExpansion` and `HsExpanded` as we have inlined them in `XXExprGhcRn` and `XXExprGhcTc`
- Ensures warnings such as
1. Pattern match checks
2. Failable patterns
3. non-() return in body statements are preserved
- Kill `HsMatchCtxt` in favor of `TcMatchAltChecker`
- Testcases:
* T18324 T20020 T23147 T22788 T15598 T22086
* T23147b (error message check),
* DoubleMatch (match inside a match for pmc check)
* pattern-fails (check pattern match with non-refutable pattern, eg. newtype)
* Simple-rec (rec statements inside do statment)
* T22788 (code snippet from #22788)
* DoExpanion1 (Error messages for body statments)
* DoExpansion2 (Error messages for bind statements)
* DoExpansion3 (Error messages for let statements)
Also repoint haddock to the right submodule so that the test (haddockHypsrcTest) pass
Metric Increase 'compile_time/bytes allocated':
T9020
The testcase is a pathalogical example of a `do`-block with many statements that do nothing.
Given that we are expanding the statements into function binds, we will have to bear
a (small) 2% cost upfront in the compiler to unroll the statements.

Lazy skolemisation for @a-binders (#17594)
This patch is a preparation for @a-binders implementation. The main changes are:
* Skolemisation is now prepared to deal with @binders.
See Note [Skolemisation overview] in GHC.Tc.Utils.Unify.
Most of the action is in
- Utils.Unify.matchExpectedFunTys
- Gen.Pat.tcMatchPats
- Gen.Expr.tcPolyExprCheck
- Gen.Binds.tcPolyCheck
Some accompanying refactoring:
* I found that funTyConAppTy_maybe was doing a lot of allocation, and
rejigged userTypeError_maybe to avoid calling it.

driver: Really don't lose track of nodes when we fail to resolve cycles
This fixes a bug in 8db8d2fd1c881032b1b360c032b6d9d072c11723, where we could lose
track of acyclic components at the start of an unresolved cycle. We now ensure we
never loose track of any of these components.
As T24275 demonstrates, a "cyclic" SCC might not really be a true SCC:
When viewed without boot files, we have a single SCC
```
[REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A [main:T24275A {-# SOURCE #-}]]
```
But with boot files this turns into
```
[NONREC main:T24275B {-# SOURCE #-} [],
REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A {-# SOURCE #-} [main:T24275B],
NONREC main:T24275A [main:T24275A {-# SOURCE #-}]]
```
Note that this is truly not an SCC, as no nodes are reachable from T24275B.hs-boot.
However, we treat this entire group as a single "SCC" because it seems so when we
analyse the graph without taking boot files into account.
Indeed, we must return a single ResolvedCycle element in the BuildPlan for this
as described in Note [Upsweep].
However, since after resolving this is not a true SCC anymore, `findCycle` fails
to find a cycle and we have a sub-optimal error message as a result.
To handle this, I extended `findCycle` to not assume its input is an SCC, and to
try harder to find cycles in its input.
Fixes #24275

ts: add compile_artifact, ignore_extension flag
In b521354216f2821e00d75f088d74081d8b236810 the testsuite gained the
capability to collect generic metrics. But this assumed that the test
was not linking and producing artifacts and we only wanted to track
object files, interface files, or build artifacts from the compiler
build. However, some backends, such as the JS backend, produce artifacts when
compiling, such as the jsexe directory which we want to track.
This patch:
- tweaks the testsuite to collect generic metrics on any build artifact
in the test directory.
- expands the exe_extension function to consider windows and adds the
ignore_extension flag.
- Modifies certain tests to add the ignore_extension flag. Tests such as
heaprof002 expect a .ps file, but on windows without ignore_extensions
the testsuite will look for foo.exe.ps. Hence the flag.
- adds the size_hello_artifact test

Javascript: Don't filter out rtsDeps list
This logic appears to be incorrect as it would drop any dependency which
was not in a direct dependency of the package being linked.
In the ghc-internals split this started to cause errors because
`ghc-internal` is not a direct dependency of most packages, and hence
important symbols to keep which are hard coded into the js runtime were
getting dropped.

base: Cleanup whitespace in cbits

44f6557a by Ben Gamari at 2024-02-08T00:35:59-05:00
Move `base` to `ghc-internal`
Here we move a good deal of the implementation of `base` into a new
package, `ghc-internal` such that it can be evolved independently
from the user-visible interfaces of `base`.
While we want to isolate implementation from interfaces, naturally, we
would like to avoid turning `base` into a mere set of module re-exports.
However, this is a non-trivial undertaking for a variety of reasons:
* `base` contains numerous known-key and wired-in things, requiring
corresponding changes in the compiler
* `base` contains a significant amount of C code and corresponding
autoconf logic, which is very fragile and difficult to break apart
* `base` has numerous import cycles, which are currently dealt with via
carefully balanced `hs-boot` files
* We must not break existing users
To accomplish this migration, I tried the following approaches:
* [Split-GHC.Base]: Break apart the GHC.Base knot to allow incremental
migration of modules into ghc-internal: this knot is simply too
intertwined to be easily pulled apart, especially given the rather
tricky import cycles that it contains)
* [Move-Core]: Moving the "core" connected component of base (roughly
150 modules) into ghc-internal. While the Haskell side of this seems
tractable, the C dependencies are very subtle to break apart.
* [Move-Incrementally]:
1. Move all of base into ghc-internal
2. Examine the module structure and begin moving obvious modules (e.g.
leaves of the import graph) back into base
3. Examine the modules remaining in ghc-internal, refactor as necessary
to facilitate further moves
4. Go to (2) iterate until the cost/benefit of further moves is
insufficient to justify continuing
5. Rename the modules moved into ghc-internal to ensure that they don't
overlap with those in base
6. For each module moved into ghc-internal, add a shim module to base
with the declarations which should be exposed and any requisite
Haddocks (thus guaranteeing that base will be insulated from changes
in the export lists of modules in ghc-internal
Here I am using the [Move-Incrementally] approach, which is empirically
the least painful of the unpleasant options above

Use specific clang assembler when compiling with -fllvm
There are situations where LLVM will produce assembly which older gcc
toolchains can't handle. For example on Deb10, it seems that LLVM >= 13
produces assembly which the default gcc doesn't support.
A more robust solution in the long term is to require a specific LLVM
compatible assembler when using -fllvm.

Generate LLVM min/max bound policy via Hadrian
Per #23966, I want the top-level configure to only generate
configuration data for Hadrian, not do any "real" tasks on its own.
This is part of that effort --- one less file generated by it.
(It is still done with a `.in` file, so in a future world non-Hadrian
also can easily create this file.)
Split modules:
- GHC.CmmToLlvm.Config
- GHC.CmmToLlvm.Version
- GHC.CmmToLlvm.Version.Bounds
- GHC.CmmToLlvm.Version.Type
This also means we can get rid of the silly `unused.h` introduced in
!6803 / 7dfcab2f4bcb7206174ea48857df1883d05e97a2 as temporary kludge.

rts: eras profiling mode
The eras profiling mode is useful for tracking the life-time of
closures. When a closure is written, the current era is recorded in the
profiling header. This records the era in which the closure was created.
* Enable with -he
* User mode: Use functions ghc-experimental module GHC.Profiling.Eras to modify the era
* Automatically: --automatic-era-increment, increases the user era on major
collections
* The first era is era 1
* -he<era> can be used with other profiling modes to select a specific
era
If you just want to record the era but not to perform heap profiling you
can use `-he --no-automatic-heap-samples`.

JS: handle stored null StablePtr
Some Haskell codes unsafely cast StablePtr into ptr to compare against
NULL. E.g. in direct-sqlite:
if castStablePtrToPtr aggStPtr /= nullPtr then
where `aggStPtr` is read (`peek`) from zeroed memory initially.
We fix this by giving these StablePtr the same representation as other
null pointers. It's safe because StablePtr at offset 0 is unused (for
this exact reason).

Support linking C sources with JS output of the JavaScript backend.
See the added documentation in the users guide.
The implementation simply extends the JS linker to use the objects (.o)
that were already produced by the emcc compiler and which were filtered
out previously. I've also added some options to control the link with C
functions (see the documentation about pragmas).
With this change I've successfully compiled the direct-sqlite package
which embeds the sqlite.c database code. Some wrappers are still
required (see the documentation about wrappers) but everything generic
enough to be reused for other libraries have been integrated into
rts/js/mem.js.

Add support for heap profiling while using the nonmoving collector.
We greatly simply the implementation by disabling concurrent collection for
GCs when heap profiling is enabled. This entails that the marked objects on
the nonmoving heap are exactly the live objects.
Note that we match the behaviour for live bytes accounting by taking the size
of objects on the nonmoving heap to be that of the segment's block
rather than the object itself.

Fix ffi callbacks with >6 args and non-64bit args.
Check for ptr/int arguments rather than 64-bit width arguments when counting
integer register arguments.
The old approach broke when we stopped using exclusively W64-sized types to represent
sub-word sized integers.
Fixes #24314

rts/EventLog: Place eliminate duplicate strlens
Previously many of the `post*` implementations would first compute the
length of the event's strings in order to determine the event length.
Later we would then end up computing the length yet again in
`postString`. Now we instead pass the string length to `postStringLen`,
avoiding the repeated work.

rts/eventlog: Place upper bound on IPE string field lengths
The strings in IPE events may be of unbounded length. Limit the lengths
of these fields to 64k characters to ensure that we don't exceed the
maximum event length.
