We now supply the non-essential options to haddock using the `extraArgs`
field, which can be specified in a Flavour so that if an advanced user
wants to change how documentation is generated then they can use
something other than the `defaultHaddockExtraArgs`.
This does have the potential to regress some packaging if a user has
overridden `extraArgs` themselves, because now they also need to add
the haddock options to extraArgs. This can easily be done by appending
`defaultHaddockExtraArgs` to their extraArgs invocation but someone
might not notice this behaviour has changed.
In any case, I think passing the non-essential options in this manner is
the right thing to do and matches what we do for the "ghc" builder,
which by default doesn't pass any optmisation levels, and would likewise
be very bad if someone didn't pass suitable `-O` levels for builds.

Commit b4d39adbb58 made 'hs_cmpxchg64()' available to all architectures.
Unfortunately this made GHC to fail to build on armel, since armel needs
libatomic to support atomic operations on 64-bit word sizes.
Configure libraries/ghc-prim/ghc-prim.cabal to link against libatomic,

This patch implements part 1 of GHC Proposal #281,
introducing explicit `type` patterns and `type` arguments.
Summary of the changes:
1. New extension flag:
RequiredTypeArguments
2. New user-facing syntax:
`type p` patterns (represented by EmbTyPat)
`type e` expressions (represented by HsEmbTy)
3. Functions with required type arguments (visible forall)
can now be defined and applied:
idv :: forall a -> a -> a -- signature (relevant change: checkVdqOK in GHC/Tc/Validity.hs)
idv (type a) (x :: a) = x -- definition (relevant change: tcPats in GHC/Tc/Gen/Pat.hs)
x = idv (type Int) 42 -- usage (relevant change: tcInstFun in GHC/Tc/Gen/App.hs)
4. template-haskell support:
TH.TypeE corresponds to HsEmbTy
TH.TypeP corresponds to EmbTyPat
5. Test cases and a new User's Guide section
Changes *not* included here are the t2t (term-to-type) transformation
and term variable capture; those belong to part 2.

This commit integrates ghc-toolchain, the brand new way of configuring
toolchains for GHC, with the Hadrian build system, with configure, and
extends and improves the first iteration of ghc-toolchain.
The general overview is
* We introduce a program invoked `ghc-toolchain --triple=...` which, when run,
produces a file with a `Target`. A `GHC.Toolchain.Target.Target`
describes the properties of a target and the toolchain (executables
and configured flags) to produce code for that target
* Hadrian was modified to read Target files, and will both
* Invoke the toolchain configured in the Target file as needed
* Produce a `settings` file for GHC based on the Target file for that stage
* `./configure` will invoke ghc-toolchain to generate target files, but
it will also generate target files based on the flags configure itself
configured (through `.in` files that are substituted)
* By default, the Targets generated by configure are still (for now) the ones used by Hadrian
* But we additionally validate the Target files generated by
ghc-toolchain against the ones generated by configure, to get a head
start on catching configuration bugs before we transition
completely.
* When we make that transition, we will want to drop a lot of the
toolchain configuration logic from configure, but keep it otherwise.
* For each compiler stage we should have 1 target file (up to a stage compiler we can't run in our machine)
* We just have a HOST target file, which we use as the target for stage0
* And a TARGET target file, which we use for stage1 (and later stages, if not cross compiling)
* Note there is no BUILD target file, because we only support cross compilation where BUILD=HOST
* (for more details on cross-compilation see discussion on !9263)

Fixes #23503.
Now the `-ddump-asm` flag is respected in the wasm backend
NCG, so developers can directly view the generated ASM instead of
needing to pass `-S` or `-keep-tmp-files` and manually find & open
the assembly file.
Ideally, we should be able to output the assembly files in smaller
chunks like in other NCG backends. This would also make dumping assembly
stats easier. However, this would require a large refactoring, so for
short-term debugging purposes I think the current approach works fine.

This commit fixes building ghc with 9.2 as the boostrap compiler.
The ghc-toolchain patch assumed all _STAGE0 options were available, and
forgot to account for this missing information in 9.2.
Ghc 9.2 does not have in settings whether ar supports -l, hence can't
report it with --info (unliked 9.4 upwards).
The fix is to default the missing information (we default "ar supports
-l" and other missing options to False)

It adds a warning -Wincomplete-record-selectors for usages of a record
field access function (either a record selector or getField @"rec"),
while trying to silence the warning whenever it can be sure that a constructor
without the record field would not be invoked (which would otherwise cause
the program to fail). For example:
data T = T1 | T2 {x :: Bool}
f a = x a -- this would throw an error
g T1 = True
g a = x a -- this would not throw an error
h :: HasField "x" r Bool => r -> Bool
h = getField @"x"
j :: T -> Bool
j = h -- this would throw an error because of the `HasField`
-- constraint being solved
See the tests DsIncompleteRecSel* and TcIncompleteRecSel for more examples of the warning.
See Note [Detecting incomplete record selectors] in GHC.HsToCore.Expr for implementation details

There have been two incidents recently where bootstrapping has been
broken by removing support for building with 9.2.*.
The process for bumping the minimum required version starts with bumping
the configure version and then other CI jobs such as the bootstrap jobs
have to be updated. We must not silently bump the minimum required
version.
Now we are running a slimmed down validate pipeline it seems worthwile
to test these bootstrap configurations in the full-ci pipeline.

EquationInfo currently contains a list of the equation's patterns together with a CoreExpr that is to be evaluated after a successful match on this equation.
All the match-functions only operate on the first pattern of an equation - after successfully matching it, match is called recursively on the tail of the pattern list.
We can express this more clearly and make the code a little more elegant by updating the datatype of EquationInfo as follows:
data EquationInfo
= EqnMatch { eqn_pat = Pat GhcTc, eqn_rest = EquationInfo }
| EqnDone { eqn_rhs = MatchResult CoreExpr }
An EquationInfo now explicitly exposes its first pattern which most functions operate on, and exposes the equation that remains after processing the first pattern. An EqnDone signifies an empty equation where the CoreExpr can now be evaluated.

Previously `ghc-prim`'s atomic wrappers used the legacy `__sync_*`
family of C builtins. Here we refactor these to rather use the
appropriate C11 atomic equivalents, allowing us to be more explicit
about the expected ordering semantics.

This MR addresses #22404. There is a big Note
Note [Occurrence analysis for join points]
that explains it all. Significant changes
* New field occ_join_points in OccEnv
* The NonRec case of occAnalBind splits into two cases:
one for existing join points (which does the special magic for
Note [Occurrence analysis for join points], and one for other
bindings.
* mkOneOcc adds in info from occ_join_points.
* All "bring into scope" activity is centralised in the
new function `addInScope`.
* I made a local data type LocalOcc for use inside the occurrence analyser
It is like OccInfo, but lacks IAmDead and IAmALoopBreaker, which in turn
makes computationns over it simpler and more efficient.
* I found quite a bit of allocation in GHC.Core.Rules.getRules
so I optimised it a bit.
More minor changes
* I found I was using (Maybe Arity) a lot, so I defined a new data
type JoinPointHood and used it everwhere. This touches a lot of
non-occ-anal files, but it makes everything more perspicuous.
* Renamed data constructor WithUsageDetails to WUD, and
WithTailUsageDetails to WTUD
This also fixes #21128, on the way.

In fact these figures seem to vary between platforms; generally worse
on i386 for some reason. The Windows numbers vary by 1% espec in
benchmarks where the total allocation is low. But the geom mean stays
solidly negative, which is good. The "increase/decrease" list below
covers all platforms.
The big win on T13253-spj comes because it has a big nest of join
points, each occurring twice in the next one. The new occ-anal takes
only one iteration of the simplifier to do the inlining; the old one
took four. Moreover, we get much smaller code with the new one:
New: Result size of Tidy Core
= {terms: 429, types: 84, coercions: 0, joins: 14/14}
Old: Result size of Tidy Core
= {terms: 2,437, types: 304, coercions: 0, joins: 10/10}
--------- Runtime perf -----------
No significant changes in nofib results, except a 1% reduction in
compiler allocation.

This commit implements the ability to deprecate certain instances,
which causes the compiler to emit the desired deprecation message
whenever they are instantiated. For example:
module A where
class C t where
instance {-# DEPRECATED "dont use" #-} C Int where
module B where
import A
f :: C t => t
f = undefined
g :: Int
g = f -- "dont use" emitted here
The implementation is as follows:
- In the parser, we parse deprecations/warnings attached to instances:
instance {-# DEPRECATED "msg" #-} Show X
deriving instance {-# WARNING "msg2" #-} Eq Y
(Note that non-standalone deriving instance declarations do not support
this mechanism.)
- We store the resulting warning message in `ClsInstDecl` (respectively, `DerivDecl`).
In `GHC.Tc.TyCl.Instance.tcClsInstDecl` (respectively, `GHC.Tc.Deriv.Utils.newDerivClsInst`),
we pass on that information to `ClsInst` (and eventually store it in `IfaceClsInst` too).
- Finally, when we solve a constraint using such an instance, in
`GHC.Tc.Instance.Class.matchInstEnv`, we emit the appropriate warning
that was stored in `ClsInst`.
Note that we only emit a warning when the instance is used in a different module
than it is defined, which keeps the behaviour in line with the deprecation of
top-level identifiers.

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.

Previously the way-specific compilation flags (e.g. `-DDEBUG`,
`-DTHREADED_RTS`) would not be passed to the CC invocations. This meant
that C dependency files would not correctly reflect
dependencies predicated on the way, resulting in the rather
painful #23554.

This commits adds more performant Enum Int64 and Enum Word64 instances
for 32-bit platforms, replacing the Integer-based implementation.
These instances are a copy of the Enum Int and Enum Word instances with
minimal changes to manipulate Int64 and Word64 instead.
On i386 this yields a 1.5x performance increase and for the JavaScript
back end it even yields a 5.6x speedup.

This reverts commit 522bd584f71ddeda21efdf0917606ce3d81ec6cc. And
takes care of the case that I missed in my previous attempt. Namely
the case of an AbsBinds with no type variables and no dictionary
variable.
Ironically, the comment explaining why non-recursive lets were
desugared to recursive lets were pointing specifically at this case
as the reason. I just failed to understand that it was until Simon PJ
pointed it out to me.

When the Win32 threaded IO manager shuts down, `ioManagerDie` sends an
`IO_MANAGER_DIE` event to the IO manager thread using the
`io_manager_event` event object. Finally, it will closes the event object,
and invalidate `io_manager_event`.
Previously, `readIOManagerEvent` would see that `io_manager_event` is
invalid and return `0`, suggesting that everything is right with the
world. This meant that if `ioManagerDie` invalidated the handle before
the event manager was blocked on the event we would end up in a
situation where the event manager would never realize it was asked to
shut down.
Fix this by ensuring that `readIOManagerEvent` instead returns
`IO_MANAGER_DIE` when we detect that the event object has been
invalidated by `ioManagerDie`.
Fixes #23691.

This modifies `splitHsApps` (a key function used in typechecking function
applications) to look through untyped TH splices and quasiquotes. Not doing so
was the cause of #21077. This builds on !7821 by making `splitHsApps` match on
`HsUntypedSpliceTop`, which contains the `ThModFinalizers` that must be run as
part of invoking the TH splice. See the new `Note [Looking through Template
Haskell splices in splitHsApps]` in `GHC.Tc.Gen.Head`.
Along the way, I needed to make the type of `splitHsApps.set` slightly more
general to accommodate the fact that the location attached to a quasiquote is
a `SrcAnn NoEpAnns` rather than a `SrcSpanAnnA`.
Fixes #21077.

Previously we incorrectly interpreted PE section numbers as signed
values. However, this isn't the case; rather, it's an unsigned 16-bit number
with a few special bit-patterns (0xffff and 0xfffe). This resulted in #22941
as the linker would conclude that the sections were invalid.
Fixing this required quite a bit of refactoring.
Closes #22941.

Fixes #17900; fixes #20195.
The existing "can_fail" and "has_side_effects" primop attributes
that previously governed this were used in inconsistent and
confusingly-documented ways, especially with regard to raising
exceptions. This patch replaces them with a single "effect"
attribute, which has four possible values: NoEffect, CanFail,
ThrowsException, and ReadWriteEffect. These are described in
Note [Classifying primop effects].
A substantial amount of related documentation has been re-drafted
for clarity and accuracy.
In the process of making this attribute format change for literally
every primop, several existing mis-classifications were detected and
corrected. One of these mis-classifications was tagToEnum#, which
is now considered CanFail; this particular fix is known to cause a
regression in performance for derived Enum instances. (See #23782.)
Fixing this is left as future work.
New primop attributes "cheap" and "work_free" were also added,
and used in the corresponding parts of GHC.Core.Utils.
In view of their actual meaning and uses, `primOpOkForSideEffects`
and `exprOkForSideEffects` have been renamed to `primOpOkToDiscard`
and `exprOkToDiscard`, respectively.

When adding an implicit parameter dictionary to the inert set, we must
make sure that it replaces any previous implicit parameter dictionaries
that overlap, in order to get the appropriate shadowing behaviour, as in
let ?x = 1 in let ?x = 2 in ?x
We were already doing this for inert_cans, but we weren't doing the same
thing for inert_solved_dicts, which lead to the bug reported in #23761.
The fix is thus to make sure that, when handling an implicit parameter
dictionary in updInertDicts, we update **both** inert_cans and
inert_solved_dicts to ensure a new implicit parameter dictionary
correctly shadows old ones.

This removes the zonk in GHC.Tc.Gen.App.tc_inst_forall_arg and its
accompanying Note [Visible type application zonk]. Indeed, this zonk
is no longer necessary, as we no longer maintain the invariant that
types are well-kinded without zonking; only that typeKind does not
crash; see Note [The Purely Kinded Type Invariant (PKTI)].
This commit removes this zonking step (as well as a secondary zonk),
and replaces the aforementioned Note with the explanatory
Note [Type application substitution], which justifies why the
substitution performed in tc_inst_forall_arg remains valid without
this zonking step.

The JavaScript code in libraries/base/jsbits/base.js had some
hardcoded offsets for fields in structs, because we expected
the layout of the data structures to remain unchanged. Emsdk
3.1.42 changed the layout of the stat struct, breaking this
assumption, and causing code in .hsc files accessing the
stat struct to fail.
This patch improves compatibility with recent emsdk by
removing the assumption that data layouts stay unchanged:
1. offsets of fields in structs used by JavaScript code are
now computed by the configure script, so both the .js and
.hsc files will automatically use the new layout if anything
changes.
2. the distrib/configure script checks that the emsdk version
on a user's system is the same version that a bindist was
booted with, to avoid data layout inconsistencies

In !10911, I deleted a `tcExpr` case for `HsUntypedSplice` in favor of a much
simpler case that simply delegates to `tcApp`. Although this passed the test
suite at the time, this was actually an error, as the previous `tcExpr` case
was critically pushing the expected type inwards. This actually matters for
programs like the one in #23796, which GHC would not accept with type inference
alone—we need full-blown type _checking_ to accept these.
I have added back the previous `tcExpr` case for `HsUntypedSplice` and now
explain why we have two different `HsUntypedSplice` cases (one in `tcExpr` and
another in `splitHsApps`) in `Note [Looking through Template Haskell splices in
splitHsApps]` in `GHC.Tc.Gen.Head`.

This commit introduces in GHC.Types.Error.Codes the function
constructorCodes :: forall diag. (...) => Map DiagnosticCode String
which computes a collection of all the diagnostic codes that correspond
to a particular type. In particular, we can compute the collection of
all diagnostic codes emitted by GHC using the invocation
constructorCodes @GhcMessage
We then make use of this functionality in the new "codes" test which
checks consistency and coverage of GHC diagnostic codes.
It performs three checks:
- check 1: all non-outdated GhcDiagnosticCode equations
are statically used.
- check 2: all outdated GhcDiagnosticCode equations
are statically unused.
- check 3: all statically used diagnostic codes are covered by
the testsuite (modulo accepted exceptions).

Currently a negative exponent less than `minBound :: Int` results in
Infinity, which is very surprising and obviously wrong.
```
λ> read "1e-9223372036854775808" :: Double
0.0
λ> read "1e-9223372036854775809" :: Double
Infinity
```
There is a further edge case where the exponent can overflow when
increased by the number of tens places in the integer part, or
underflow when decreased by the number of leading zeros in the
fractional part if the integer part is zero:
```
λ> read "10e9223372036854775807" :: Double
0.0
λ> read "0.01e-9223372036854775808" :: Double
Infinity
```
To resolve both of these issues, perform all arithmetic and
comparisons involving the exponent in type `Integer`. This approach
also eliminates the need to explicitly check the exponent against
`maxBound :: Int` and `minBound :: Int`, because the allowed range
of the exponent (i.e. the result of `floatRange` for the target
floating point type) is certainly within those bounds.

The duplication between `exprIsTrivial` and `getIdFromTrivialExpr_maybe` has
been bugging me for a long time.
This patch introduces an inlinable worker function `trivial_expr_fold` acting
as the single, shared decision procedure of triviality. It "returns" a
Church-encoded `Maybe (Maybe Id)`, so when it is inlined, it fuses to similar
code as before.
(Better code, even, in the case of `getIdFromTrivialExpr` which presently
allocates a `Just` constructor that cancels away after this patch.)

This instates the invariant that a trivial CoreExpr translates to an atomic
StgExpr. Nice.
Annoyingly, in -O0 we sometimes generate
```
foo = case "blah"# of sat { __DEFAULT -> unpackCString# sat }
```
which makes it a bit harder to spot that we can emit a standard
`stg_unpack_cstring` thunk.
Fixes #23270.

We eliminate EmptyCase by way of `coreToStg (Case e _ _ []) = coreToStg e` now.
The main reason is that it plays far better in conjunction with eta expansion
(as we aim to do for arguments in CorePrep, #23083), because we can discard
any arguments, `(case e of {}) eta == case e of {}`, whereas in `(e |> co) eta`
it's impossible to discard the argument.
We do also give the same treatment to unsafeCoerce proofs and treat them as
trivial iff their RHS is trivial.
It is also both much simpler to describe than the previous mechanism of emitting
an unsafe coercion and simpler to implement, removing quite a bit of commentary
and `CorePrepProv`.
In the ghc/alloc perf test `LargeRecord`, we introduce an additional Simplifier
iteration due to #17910. E.g., FloatOut produces a binding
```
lvl_s6uK [Occ=Once1] :: GHC.Types.Int
[LclId]
lvl_s6uK = GHC.Types.I# 2#
lvl_s6uL [Occ=Once1] :: GHC.Types.Any
[LclId]
lvl_s6uL
= case Unsafe.Coerce.unsafeEqualityProof ... of
{ Unsafe.Coerce.UnsafeRefl v2_i6tr -> lvl_s6uK `cast` (... v2_i6tr ...)
}
```
That occurs once and hence is pre-inlined unconditionally in the next Simplifier
pass. It's non-trivial to find a way around that, but not really harmful
otherwise. Hence we accept a 1.2% increase on some architectures.
Metric Increase:
LargeRecord

Previously, we'd only eta expand let bindings and lambdas,
now we'll also eta expand arguments such as in T23083:
```hs
g f h = f (h `seq` (h $))
```
Unless `-fpedantic-bottoms` is set, we'll now transform to
```hs
g f h = f (\eta -> h eta)
```
in CorePrep.
See the new `Note [Eta expansion of arguments in CorePrep]` for the details.
We only do this optimisation with -O2 because we saw 2-3% ghc/alloc regressions
in T4801 and T5321FD.
Fixes #23083.

The -fno-info-table-map-with-stack flag omits STACK info tables from the info
table map, and the -fno-info-table-map-with-fallback flag omits info tables
with defaulted source locations from the map. In a test on the Agda codebase
the build results were about 7% smaller when both of those types of tables
were omitted.
Adds a test that verifies that passing each combination of these flags
results in the correct output for -dipe-stats, which is disabled for the js
backend since profiling is not implemented.
This commit also refactors a lot of the logic around extracting info tables
from the Cmm results and building the info table map.
This commit also fixes some issues in the users guide rst source to fix
warnings that were noticed while debugging the documentation for these flags.

We were installing two copies of the manpage:
* One useless one in the `share/doc` folder, because we copy the doc/
folder into share/
* The one we deliberately installed into `share/man` etc
The solution is to build the manpage into the `manpage` directory when
building the bindist, and then just install it separately.

This commit ensures that we emit the appropriate warnings when
a deprecated record field bound by a record wildcard is used.
For example:
module A where
data Foo = Foo {x :: Int, y :: Bool, z :: Char}
{-# DEPRECATED x "Don't use x" #-}
{-# WARNING y "Don't use y" #-}
module B where
import A
foo (Foo {..}) = x
This will cause us to emit a "Don't use x" warning, with location the
location of the record wildcard. Note that we don't warn about `y`,
because it is unused in the RHS of `foo`.

* We now represent a job group a triple of Maybes, which makes it easier
to work out when jobs are enabled/disabled on certain pipelines.
```
data JobGroup a = StandardTriple { v :: Maybe (NamedJob a)
, n :: Maybe (NamedJob a)
, r :: Maybe (NamedJob a) }
```
* `jobs-metadata.json` generation is reworked using the following
algorithm.
- For each pipeline type, find all the platforms we are doing builds
for.
- Select one build per platform
- Zip together the results
This way we can choose different pipelines for validate/nightly/release
which makes the metadata also useful for validate pipelines. This
feature is used by the test-primops downstream CI in order to select the
right bindist for testing validate pipelines.
This makes it easier to inspect which jobs are going to be enabled on a
particular pipeline.

In particular we now distinguish between whether we are dealing with a
Nightly/Release pipeline (which labels don't matter for) and a validate
pipeline where labels do matter.
The overall goal here is to allow a disjunction of labels for validate
pipelines, for example,
> Run a job if we have the full-ci label or test-primops label
Therefore the "ValidateOnly" rules are treated as a set of disjunctions
rather than conjunctions like before.
What this means in particular is that if we want to ONLY run a job if a
label is set, for example, "FreeBSD" label then we have to override the
whole label set.

At the moment we need ghc-toolchain to precisely match the output as
provided by the normal configure script. The normal configure script
(FP_HSCPP_CMD_WITH_ARGS) branches on whether we are using clang or gcc
so we match that logic exactly in ghc-toolchain.
The old implementation (which checks if certain flags are supported) is
better but for now we have to match to catch any potential errors in the
configuration.

The current user interface to configuring target toolchains is `./configure`.
In !9263 we added a new tool to configure target toolchains called
`ghc-toolchain`, but the blessed way of creating these toolchains is
still through configure.
However, we were not passing the user-specified options given with the
`./configure` invocation to the ghc-toolchain tool.
This commit remedies that by storing the user options and environment
variables in USER_* variables, which then get passed to GHC-toolchain.
The exception to the rule is the windows bundled toolchain, which
overrides the USER_* variables with whatever flags the windows bundled
toolchain requires to work.
We consider the bundled toolchain to be effectively the user specifying
options, since the actual user delegated that configuration work.
Closes #23678

On javascript there isn't a choice of toolchain but some of the
configure checks were not accurately providing the correct answer.
1. The linker was reported as gnu LD because the --version output
mentioned gnu LD.
2. The --target flag makes no sense on javascript but it was just
ignored by the linker, so we add a special case to stop ghc-toolchain
thinking that emcc supports --target when used as a linker.

On some platforms - ie darwin, javascript etc we really do not want to

leads to all kinds of bugs. Therefore it is a bit more prudant to add a
whitelist which specifies on which platforms it might be possible to use
a different linker.

In ghc-toolchain, we were only /not/ configuring required flags when the
user specified any flags at all for the of the HsCpp and Cpp tools.
Otherwise, the linker takes into consideration the user specified flags
to determine whether to search for a better linker implementation, but
already configured the remaining GHC and platform-specific flags
regardless of the user options.
Other Tools consider the user options as a baseline for further
configuration (see `findProgram`), so #23689 is not applicable.

When a class instance has an Unsatisfiable constraint in its context
and the user has not explicitly provided an implementation of a method,
we now always provide a RHS of the form `unsatisfiable @msg`, even
if the method has a default definition available. This ensures that,
when deferring type errors, users get the appropriate error message
instead of a possible runtime loop, if class default methods were
defined recursively.

Here we refactor that treatment of the worker thread used by the
nonmoving GC for concurrent marking, avoiding creating a new thread with
every major GC cycle. As well, the new scheme is considerably easier to
reason about, consolidating all state in one place, accessed via a small
set of accessors with clear semantics.

The AnnSortKey is used to keep track of the order of declarations for
printing when the container has split them apart.
This applies to HsValBinds and ClassDecl, ClsInstDecl.
When making modifications to the list of declarations, the new order
must be captured for when it must be printed. For each list of
declarations (binds and sigs for a HsValBind) we can just store the
list in order.
To recreate the list when printing, we must merge them, and this is
what the AnnSortKey records. It used to be indexed by SrcSpan, we now
simply index by a marker as to which list to take the next item from.

This commit gets rid of the pattern synonym error recovery mechanism
(recoverPSB). The rationale is that the fake pattern synonym binding
that the recovery mechanism introduced could lead to undesirable
knock-on errors, and it isn't really feasible to conjure up a
satisfactory binding as pattern synonyms can be used both in expressions
and patterns.
See Note [Pattern synonym error recovery] in GHC.Tc.TyCl.PatSyn.
It isn't such a big deal to eagerly fail compilation on a pattern synonym
that doesn't typecheck anyway.

This commit splits up the windows toolchain setup logic into two
functions.
* FP_INSTALL_WINDOWS_TOOLCHAIN - deals with downloading the toolchain if
it isn't already downloaded
* FP_SETUP_WINDOWS_TOOLCHAIN - sets the environment variables to point
to the correct place
FP_SETUP_WINDOWS_TOOLCHAIN is abstracted from the location of the mingw
toolchain and also the eventual location where we will install the
toolchain in the installed bindist.

The config.mk.in script was relying on some variables which were
supposed to be set by build.mk but therefore never were when used to
install a bindist.
Specifically
* BUILD_PROF_LIBS to determine whether we had profiled libraries or not
* DYNAMIC_GHC_PROGRAMS to determine whether we had shared libraries or
not
Not only were these never set but also not really accurate because you
could have shared libaries but still statically linked ghc executable.
In addition variables like GhcLibWays were just never used, so those
have been deleted from the script.
Now instead we generate a build.mk file which just directly specifies
which RtsWays we have supplied in the bindist and whether we have
DYNAMIC_GHC_PROGRAMS.

This adds a command line option to build a "relocatable" bindist.
The bindist is created by first creating a normal bindist and then
installing it using the `RelocatableBuild=YES` option. This creates a
bindist without any wrapper scripts pointing to the libdir.
The motivation for this feature is that we want to ship relocatable
bindists on windows and this method is more uniform than the ad-hoc
method which lead to bugs such as #23608 and #23476
The relocatable bindist can be built with the "reloc-binary-dist" target
and supports the same suffixes as the normal "binary-dist" command to
specify the compression style.

test the changes. Without him it would have taken ages to tweak
everything.

This commit greatly refactors the way we compute estimated provenance for stack
info tables. Previously, this process was done using an entirely separate traversal
of the whole Cmm code stream to build the map from info tables to source locations.
The separate traversal is now fused with the Cmm code generation pipeline in
GHC.Driver.Main.
This results in very significant code generation speed ups when -finfo-table-map is
enabled. In testing, this patch reduces code generation times by almost 30% with
-finfo-table-map and -O0, and 60% with -finfo-table-map and -O1 or -O2 .

CorePrep: Eliminate EmptyCase and unsafeEqualityProof in CoreToStg instead
We eliminate EmptyCase by way of `coreToStg (Case e _ _ []) = coreToStg e` now.
The main reason is that it plays far better in conjunction with eta expansion
(as we aim to do for arguments in CorePrep, #23083), because we can discard
any arguments, `(case e of {}) eta == case e of {}`, whereas in `(e |> co) eta`
it's impossible to discard the argument.

This commit implements [amendment 604](https://github.com/ghc-proposals/ghc-proposals/pull/604/)
to [GHC proposal 448](https://github.com/ghc-proposals/ghc-proposals/pull/448)
by removing the implication of language extensions
ScopedTypeVariables => TypeAbstractions
To limit breakage, we now allow type arguments in constructor patterns
when both ScopedTypeVariables and TypeApplications are enabled, but
we emit a warning notifying the user that this is deprecated behaviour
that will go away starting in GHC 9.12.
Fixes #23776

Resolves #23540, #23120
This adds spans to certain expressions in the typechecker and renamer,
and lets 'toHie' make use of those spans. Therefore the relevant
evidence uses for the following syntax will now show up under the
expected nodes in 'HieAst's:
- Overloaded literals ('IsString', 'Num', 'Fractional')
- Natural patterns and N+k patterns ('Eq', 'Ord', and instances from the
overloaded literals being matched on)
- Arithmetic sequences ('Enum')
- Monadic bind statements ('Monad')
- Monadic body statements ('Monad', 'Alternative')
- ApplicativeDo ('Applicative', 'Functor')
- Overloaded lists ('IsList')
Also see Note [Source locations for implicit function calls]
In the process of handling overloaded lists I added an extra 'SrcSpan'
field to 'VAExpansion' - this allows us to more accurately reconstruct
the locations from the renamer in 'rebuildHsApps'. This also happens to
fix #23120.
See the additions to Note [Looking through HsExpanded]

We used to bundle all children of the parent Avail with things that

In the Lint failure in #23938, we start with a coercion Refl :: T a ~R T a,
and call mkSelCo (SelTyCon 1 nominal) Refl.
The function incorrectly returned Refl :: a ~R a. The returned role
should be nominal, according to the SelCo rule:
co : (T s1..sn) ~r0 (T t1..tn)
r = tyConRole tc r0 i
----------------------------------
SelCo (SelTyCon i r) : si ~r ti
In this test case, r is nominal while r0 is representational.

The stage violation results in out-of-bound names in splices.
Technically this is an error, but someone might rely on this!?
Internal changes:
- we now track stages for TyVars.
- thLevel (RunSplice _) = 0, instead of panic, as reifyInstances does
in fact rename its argument type, and it can contain variables.

Fixes #22012 by adding the symbols described in
https://github.com/llvm/llvm-project/blob/main/llvm/docs/Atomics.rst#libcalls-atomic.
Ultimately this would be better addressed by #22011, but this is a first
step in the right direction and fixes the immediate symptom.
Note that we dropped the `__arch64_cas16` operations as these provided
by all platforms's compilers. Also, we don't link directly against the
libgcc/compiler-rt definitions but rather provide our own wrappers to
work around broken toolchains (e.g. https://bugs.gentoo.org/868018).

Supplement the existing power 2 sized nonmoving allocators with a family
of dense allocators up to a configurable threshold.
This should reduce waste from rounding up block sizes while keeping the
amount of allocator sizes manageable.
This patch:
- Adds a new configuration option `--nonmoving-dense-allocator-count`
to control the amount of these new dense allocators.
- Adds some constants to `NonmovingAllocator` in order to keep
marking fast with the new allocators.
Resolves #23340

As the Lint error in #23952 showed, the function adjustJoinPointType
was failing to adjust the FunTyFlag when adjusting the type.
I don't think this caused the seg-fault reported in the ticket,
but it is definitely. This patch fixes it.
It is tricky to come up a small test case; Krzysztof came up with
this one, but it only triggers a failure in GHC 9.6.

This commit adjusts the validity checking of data family
instances to improve the reporting of unused type variables.
See Note [Out of scope tvs in data family instances] in GHC.Tc.Validity.
The problem was that, in a situation such as
data family D :: Type
data instance forall (d :: Type). D = MkD
the RHS passed to 'checkFamPatBinders' would be the TyCon app
R:D d
which mentions the type variable 'd' quantified in the user-written
forall. Thus, when computing the set of unused type variables in
the RHS of the data family instance, we would find that 'd' is used,
and report a strange error message that would say that 'd' is not
bound on the LHS.
To fix this, we special-case the data-family instance case,
manually extracting all the type variables that appear in the
arguments of all the data constructores of the data family instance.

This commit changes how we perform some validity checking for
coercion axioms to mirror how we handle default declarations for
associated type families. This allows us to keep track of whether
type variables in type and data family instances were user-written
or not, in order to only report the user-written ones in
"unused type variable" error messages.
Consider for example:
{-# LANGUAGE PolyKinds #-}
type family F
type instance forall a. F = ()
In this case, we get two quantified type variables,
(k :: Type) and (a :: k); the second being user-written, but the first
is introduced by the typechecker. We should only report 'a' as being
unused, as the user has no idea what 'k' is.

This is a hack to get around the cabal function we're calling
*decreasing* the verbosity it passes to another function, which is the
stuff we often actually care about. Sigh.
Keeping this a separate commit so if this makes things too verbose it is
easy to revert.

This is much more terse because we are programmatically handling the
leading underscore.
`findPtr` however is still handled in the Cabal file because we need a
newer Cabal to pass flags to the configure script automatically.

Clean up the m4 to handle the auto case always and be more consistent.
Also simplify the CPP --- we should always have both headers if we are
using libnuma.
"side effects" (AC_DEFINE, and AC_SUBST) are removed from the macros to
better separate searching from actions taken based on search results.
This might seem overkill now, but will make shuffling logic between
configure scripts easier later.
The macro comments are converted from `dnl` to `#` following the
recomendation in
https://www.gnu.org/software/autoconf/manual/autoconf-2.71/html_node/Macro-Definitions.html

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.

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:

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!

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.

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.

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.

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.

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.

The RTS configure one has a new
```
AC_CHECK_SIZEOF([void *])

`ac_cv_sizeof_void_p` is defined. Once more code is moved over in latter

not guarantee that we get some negative values, and while we try to
special case most, we should exclude negative indexing into the sections

This change ensure that the reg + offset computation is always of the
same size. Before this we could end up with a 64bit register, and then
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 #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.

The linker however, failed to mask the `SYM_TYPE_DUP_DISCARD` value.

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.

vfun (type (Maybe Int))

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]
Left as future work: checking for puns.

It tries to cover the cases of multiple threads waiting on the same
fd for reading and multiple threads waiting for writing, including
wait cancellation by async exceptions.
It should work for any I/O manager, in-RTS or in-Haskell.
Unfortunately it will not currently work for Windows because it relies
on anonymous unix sockets. It could in principle be ported to use
Windows named pipes.

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.

Fixes #24167
XCode 15 introduced a new linker which warns on duplicate libraries being
linked. To disable this warning, we pass -Wl,-no_warn_duplicate_libraries as
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.

`genFMA3Code` assumed that we had to take extra precations to avoid overwriting

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.

* 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

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).
See the new function pat_to_type_pat in compiler/GHC/Tc/Gen/Pat.hs

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).
Closes #18461 and #18739

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
lib/bin folder anymore.
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.

I don't understand much about the debugger but the code should be better
than it was.

* In GHC.StgToByteCode, replace bcIdPrimId with idPrimRep,
bcIdArgRep with idArgRep, atomPrimRep with stgArgRep1.
All of them were duplicates.
* In GHC.Stg.Unarise, we were converting a PrimRep to a Type and back to
PrimRep. Remove the calls to primRepToType and typePrimRep1 which cancel out.
* In GHC.STG.Lint, GHC.StgToCmm, GHC.Types.RepType we were filtering out
VoidRep from the result of typePrimRep. But typePrimRep never returns
VoidRep - remove the filtering.

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`.

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)

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 were emitting the wrong instructions for fused multiply-add
operations on LLVM:
- the instruction name is "llvm.fma.f32" or "llvm.fma.f64", not "fmadd"
- LLVM does not support other instructions such as "fmsub"; instead
we implement these by flipping signs of some arguments
- the instruction is an LLVM intrinsic, which requires handling it
like a normal function call instead of a machine instruction

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`.

This MachOp provides a convenient way to do so without breaking the

GHC.Cmm.GenericOpt. The main motivation is enabling this logic to be
run in the wasm backend NCG code, which is defined in other modules
that's imported by GHC.CmmToAsm, causing a cyclic dependency issue.

This commit enables the generic cmm optimizations in other NCGs to be
run in the wasm backend as well, followed by a late cmm control-flow
optimization pass. The added optimizations do catch some corner cases
not handled by the pre-NCG cmm pipeline and are useful in generating
smaller CFGs.

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.

...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.

- 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.

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

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.

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

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.

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

This change fixes a Haddock regression (introduced in 19e80b9af252)
that affected leading comments on infix data constructor declarations:

There are situations where LLVM will produce assembly which older gcc

A more robust solution in the long term is to require a specific LLVM

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.

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`.

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.

cache:INFO: - ok
Cf https://github.com/emscripten-core/emscripten/issues/18607
This breaks our tests matching the stderr output. We avoid this by setting EMCC_LOGGING=0

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.

The post-linker.mjs/prelude.js files are now distributed in the
bindist libdir, so when using the wasm backend's JSFFI feature, the
user wouldn't need to fetch them from a ghc checkout manually.

This commit adds opts.target_wrapper which allows overriding the
target wrapper on a per test case basis when testing a cross target.
This is used when testing the wasm backend's JSFFI functionality; the
rest of the cases are tested using wasmtime, though the jsffi cases
are tested using the node.js based test runner.

GHC Proposal 448 introduces binders for invisible type arguments
(@a-binders) in various contexts. This patch implements @-binders
in lambda patterns and function equations:
{-# LANGUAGE TypeAbstractions #-}
id1 :: a -> a
id1 @t x = x :: t -- @t-binder on the LHS of a function equation
higherRank :: (forall a. (Num a, Bounded a) => a -> a) -> (Int8, Int16)
higherRank f = (f 42, f 42)
ex :: (Int8, Int16)
ex = higherRank (\ @a x -> maxBound @a - x )
-- @a-binder in a lambda pattern in an argument
-- to a higher-order function
Syntax
------
To represent those @-binders in the AST, the list of patterns in Match
now uses ArgPat instead of Pat:
data Match p body
= Match {
...
- m_pats :: [LPat p],
+ m_pats :: [LArgPat p],
...
}
+ data ArgPat pass
+ = VisPat (XVisPat pass) (LPat pass)
+ | InvisPat (XInvisPat pass) (HsTyPat (NoGhcTc pass))
+ | XArgPat !(XXArgPat pass)
The VisPat constructor represents patterns for visible arguments,
which include ordinary value-level arguments and required type arguments
(neither is prefixed with a @), while InvisPat represents invisible type
arguments (prefixed with a @).
Parser
------
In the grammar (Parser.y), the lambda and lambda-cases productions of
aexp non-terminal were updated to accept argpats instead of apats:
aexp : ...
- | '\\' apats '->' exp
+ | '\\' argpats '->' exp
...
- | '\\' 'lcases' altslist(apats)
+ | '\\' 'lcases' altslist(argpats)
...
+ argpat : apat
+ | PREFIX_AT atype
Function left-hand sides did not require any changes to the grammar, as
they were already parsed with productions capable of parsing @-binders.
Those binders were being rejected in post-processing (isFunLhs), and now
we accept them.
In Parser.PostProcess, patterns are constructed with the help of
PatBuilder, which is used as an intermediate data structure when
disambiguating between FunBind and PatBind. In this patch we define
ArgPatBuilder to accompany PatBuilder. ArgPatBuilder is a short-lived
data structure produced in isFunLhs and consumed in checkFunBind.
Renamer
-------
Renaming of @-binders builds upon prior work on type patterns,
implemented in 2afbddb0f24, which guarantees proper scoping and
shadowing behavior of bound type variables.
This patch merely defines rnLArgPatsAndThen to process a mix of visible
and invisible patterns:
+ rnLArgPatsAndThen :: NameMaker -> [LArgPat GhcPs] -> CpsRn [LArgPat GhcRn]
+ rnLArgPatsAndThen mk = mapM (wrapSrcSpanCps rnArgPatAndThen) where
+ rnArgPatAndThen (VisPat x p) = ... rnLPatAndThen ...
+ rnArgPatAndThen (InvisPat _ tp) = ... rnHsTyPat ...
Common logic between rnArgPats and rnPats is factored out into the
rn_pats_general helper.
Type checker
------------
Type-checking of @-binders builds upon prior work on lazy skolemisation,
implemented in f5d3e03c56f.
This patch extends tcMatchPats to handle @-binders. Now it takes and
returns a list of LArgPat rather than LPat:
tcMatchPats ::
...
- -> [LPat GhcRn]
+ -> [LArgPat GhcRn]
...
- -> TcM ([LPat GhcTc], a)
+ -> TcM ([LArgPat GhcTc], a)
Invisible binders in the Match are matched up with invisible (Specified)
foralls in the type. This is done with a new clause in the `loop` worker
of tcMatchPats:
loop :: [LArgPat GhcRn] -> [ExpPatType] -> TcM ([LArgPat GhcTc], a)
loop (L l apat : pats) (ExpForAllPatTy (Bndr tv vis) : pat_tys)
...
-- NEW CLAUSE:
| InvisPat _ tp <- apat, isSpecifiedForAllTyFlag vis
= ...
In addition to that, tcMatchPats no longer discards type patterns. This
is done by filterOutErasedPats in the desugarer instead.

We must generate the hsc2hs wrapper at bindist installation time since
it must contain `--lflag` and `--cflag` arguments which depend upon the
installation path.
The solution here is to substitute these variables in the configure
script (see mk/hsc2hs.in). This is then copied over a dummy wrapper in
the install rules.
Fixes #24050.

Namespace specifiers were added to syntax of fixity signatures:
- sigdecl ::= infix prec ops | ...
+ sigdecl ::= infix prec namespace_spec ops | ...
To preserve namespace during renaming MiniFixityEnv type
now has separate FastStringEnv fields for names that should be
on the term level and for name that should be on the type level.
makeMiniFixityEnv function was changed to fill MiniFixityEnv in the right way:
- signatures without namespace specifiers fill both fields
- signatures with 'data' specifier fill data field only
- signatures with 'type' specifier fill type field only
Was added helper function lookupMiniFixityEnv that takes care about
looking for a name in an appropriate namespace.

This commit removes the unused HAVE_C11_ATOMICS macro. We used to have
a few places that have fallback paths when HAVE_C11_ATOMICS is not
defined, but that is completely redundant, since the
FP_CC_SUPPORTS__ATOMICS configure check will fail when the C compiler
doesn't support C11 style atomics. There are also many places (e.g. in
unreg backend, SMP.h, library cbits, etc) where we unconditionally use
C11 style atomics anyway which work in even CentOS 7 (gcc 4.8), the
oldest distro we test in our CI, so there's no value in keeping
HAVE_C11_ATOMICS.

Currently `ghc -M` fails to account for `.hs-boot` files correctly,
leading to issues with cross-package one-shot builds failing. This
currently manifests in `GHC.Exception` due to the boot file for
`GHC.Internal.Stack`. Work around this by adding an explicit `import`,
ensuring that `GHC.Internal.Stack` is built before `GHC.Exception`.
See #24436.

This commit passes -j to hadrian in the hadrian/hie-bios scripts. When
the user starts HLS in a fresh clone that has just been configured, it
takes quite a while for hie-bios to pick up the ghc flags and start
actual indexing, due to the fact that the hadrian build step defaulted
to -j1, so -j speeds things up and improve HLS user experience in GHC.
Also add -j flag to .ghcid to speed up ghcid, and sets the Windows
build root to .hie-bios which also works and unifies with other
platforms, the previous build root _hie-bios was missing from
.gitignore anyway.

When calling as `cc`, GCC does not outputs lowercased "gcc" at least in 13.2.1 version here.
```
$ cc --version
cc (GCC) 13.2.1 20230801
...
```
This fails the check and outputs the confusing message: `configure: $CC is not gcc; assuming it's a reasonably new C compiler`
This patch makes it check for upper-cased "GCC" too so that it works correctly:
```

Its payload was used only for a small optimization in genAlts,
avoiding a few assignments for programs of this form:
case NormalDataCon arg1 arg2 of x { NormalDataCon x1 x2 -> ... ; }
But when compiling with optimizations, this sort of code is
generally eliminated by case-of-known-constructor in Core-to-Core.
So it doesn't seem worth tracking and cleaning up again in StgToJS.

In nonmovingTidyWeaks we want to check if the key of a weak pointer
lives in the non-moving heap. We do this by checking the flags of the
block the key lives in. But we need to be careful with values that live
outside the Haskell heap, since they will lack a block descriptor and
looking for one may lead to a segfault. In this case we should just
accept that it isn't on the non-moving heap.

T23540 is fragile on 32-bit platforms. The root cause is usage of
`getEvidenceTreesAtPoint`, which internally relies on `Name`'s `Ord`
instance, which is indeterministic. The solution is adding a
deterministic `Ord` instance for `EvidenceInfo` and sorting the
evidence trees before pretty printing. Fixes #24449.

This implements Proposal 0475, introducing the `ListTuplePuns` extension
which is enabled by default.
Disabling this extension makes it invalid to refer to list, tuple and
sum type constructors by using built-in syntax like `[Int]`,
`(Int, Int)`, `(# Int#, Int# #)` or `(# Int | Int #)`.
Instead, this syntax exclusively denotes data constructors for use with
`DataKinds`.
The conventional way of referring to these data constructors by
prefixing them with a single quote (`'(Int, Int)`) is now a parser
error.
Tuple declarations have been moved to `GHC.Tuple.Prim` and the `Solo`
data constructor has been renamed to `MkSolo` (in a previous commit).
Unboxed tuples and sums now have real source declarations in `GHC.Types`.
Unit and solo types for tuples are now called `Unit`, `Unit#`, `Solo`
and `Solo#`.
Constraint tuples now have the unambiguous type constructors `CTuple<n>`
as well as `CUnit` and `CSolo`, defined in `GHC.Classes` like before.
A new parser construct has been added for the unboxed sum data
constructor declarations.
The type families `Tuple`, `Sum#` etc. that were intended to provide
nicer syntax have been omitted from this change set due to inference
problems, to be implemented at a later time.

There were a few issues with the hackage links:
1. We were using the package id rather than the package name for the
package links. This is fixed by now allowing the template to mention
%pkg% or %pkgid% and substituing both appropiatly.
2. The `--haddock-base-url` flag is renamed to `--haddock-for-hackage`
as the new base link works on a local or remote hackage server.
3. The "src" path including too much stuff, so cross-package source
links were broken as the template was getting double expanded.
Fixes #24086

These were changes are all triggered by #24471.
1. Make GHC.Core.Opt.SetLevels.lvlMFE behave better when there are
many free variables. See Note [Large free-variable sets].
2. Make GHC.Core.Opt.Arity.floatIn a bit lazier in its Cost argument.
This benefits the common case where the ArityType turns out to
be nullary. See Note [Care with nested expressions]
3. Make GHC.CoreToStg.Prep.cpeArg behave for deeply-nested
expressions. See Note [Eta expansion of arguments in CorePrep]
wrinkle (EA2).
Compile times go down by up to 4.5%, and much more in artificial
cases. (Geo mean of compiler/perf changes is -0.4%.)

* Main change: make the error message generated by mkFunTysMsg more
accurate by changing "value arguments" to "visible arguments".
* Refactor: define a new type synonym VisArity and use it instead of
Arity in a few places.
It might be the case that there other places in the compiler that should
talk about visible arguments rather than value arguments, but I haven't
tried to find them all, focusing only on the error message reported in
the ticket.

Here we introduce the `Backtraces` type and associated machinery for
attaching these via `ExceptionContext`. These has a few compile-time
regressions (`T15703` and `T9872d`) due to the additional dependencies
in the exception machinery.
As well, there is a surprisingly large regression in the
`size_hello_artifact` test. This appears to be due to various `Integer` and
`Read` bits now being reachable at link-time. I believe it should be
possible to avoid this but I have accepted the change for now to get the
feature merged.

This fixes a regression in retainer set profiling introduced by
b0293f78cb6acf2540389e22bdda420d0ab874da. Prior to that commit
the heap traversal word would be initialized by `SET_HDR` using
`LDV_RECORD_CREATE`. However, the commit added a `doingLDVProfiling`
check in `LDV_RECORD_CREATE`, meaning that this initialization no longer
happened.
Given that this initialization was awkwardly indirectly anyways, I have
fixed this by explicitly initializating the heap traversal word to
`NULL` in `SET_PROF_HDR`. This is equivalent to the previous behavior,
but much more direct.
Fixes #24513.

The main purpose of this is to tuck the module name `xxx` in `module xxx where` into the hieAst.
It should fix #24493.
The following have been done:
1. Renamed and update the `tcg_doc_hdr :: Maybe (LHsDoc GhcRn)` to `tcg_hdr_info :: (Maybe (LHsDoc GhcRn), Maybe (XRec GhcRn ModuleName))`
To store the located module name information.
2. update the `RenamedSource` and `RenamedStuff` with extra `Maybe (XRec GhcRn ModuleName)` located module name information.
3. add test `testsuite/tests/hiefile/should_compile/T24493.hs` to ensure the module name is added and update several relevent tests.
4. accompanied submodule haddoc test update MR in https://gitlab.haskell.org/ghc/haddock/-/merge_requests/53

This replicates the behavior on Windows, where `Hi.exe` will produce

Previously we would eagerly allocate `InfoTableEnt`s for each
info table registered in the info table provenance map. However, this
costs considerable memory and initialization time. Instead we now
lazily decode these tables. This allows us to use one-third the memory
*and* opens the door to taking advantage of sharing opportunities within
a module.
This required considerable reworking since lookupIPE now must be passed
its result buffer.

This reverts commit 615eb855416ce536e02ed935ecc5a6f25519ae16. It was
originally intended to fix #24449, but it was merely sweeping the bug
under the rug. 3836a110577b5c9343915fd96c1b2c64217e0082 has properly
fixed the fragile test, and we no longer need the C version of genSym.
Furthermore, the C implementation causes trouble when compiling with
clang that targets i386 due to alignment warning and libatomic linking
issue, so it makes sense to revert it.

This commit fixes an unnoticed out-of-bound memory access of genSym on
32-bit. ghc_unique_inc is 32-bit sized/aligned on 32-bit platforms,
but we mistakenly treat it as a Word64 pointer in genSym, and
therefore will accidentally load 2 garbage higher bytes, or with a
small but non-zero chance, overwrite something else in the data
section depends on how the linker places the data segments. This
regression was introduced in !11802 and fixed here.

Without an understanding of immutable vs. mutable memory, the index
primop family have a potentially non-intuitive type signature:
indexOffAddr :: Addr# -> Int# -> a
readOffAddr :: Addr# -> Int# -> State# d -> (# State# d, a #)
indexOffAddr# might seem like a free generality improvement, which it
certainly is not!
This change adds a brief note on mutability expectations for most
index/read/write access primops.

During heap analysis, we noticed that during generation of
'mi_extra_decls' we have lots of duplicates for the instances:
* `IfaceTyConInfo NotPromoted IfaceNormalTyCon`
* `IfaceTyConInfo IsPromoted IfaceNormalTyCon`
which should be shared instead of duplicated. This duplication increased
the number of live bytes by around 200MB while loading the agda codebase
into GHCi.
These instances are created during `CoreToIface` translation, in
particular `toIfaceTyCon`.
The generated core looks like:
toIfaceTyCon
= \ tc_sjJw ->
case $wtoIfaceTyCon tc_sjJw of
{ (# ww_sjJz, ww1_sjNL, ww2_sjNM #) ->
IfaceTyCon ww_sjJz (IfaceTyConInfo ww1_sjNL ww2_sjNM)
}
whichs removes causes the sharing to work propery.
Adding explicit sharing, with NOINLINE annotations, changes the core to:
toIfaceTyCon
= \ tc_sjJq ->
case $wtoIfaceTyCon tc_sjJq of { (# ww_sjNB, ww1_sjNC #) ->
IfaceTyCon ww_sjNB ww1_sjNC
}
which looks much more like sharing is happening.
We confirmed via ghc-debug that all duplications were eliminated and the
number of live bytes are noticeably reduced.

Uses responseFile syntax.
The issue arises when GHC is installed on windows into a location that
has a space, for example the user name is 'Fake User'.
The $topdir will also contain a space, consequentially.
When we resolve the top dir in the string `-I$topdir/mingw/include`,
then `words` will turn this single argument into `-I/C/Users/Fake` and
`User/.../mingw/include` which trips up the flag argument parser of
various tools such as gcc or clang.
We avoid this by escaping the $topdir before replacing it in
`initSettngs`.
Additionally, we allow to escape spaces and quotation marks for
arguments in `settings` file.
Add regression test case to count the number of options after variable
expansion and argument escaping took place.
Additionally, we check that escaped spaces and double quotation marks are
correctly parsed.

Before this patch, the global package database was always assumed to be
in libdir </> package.conf.d.
This causes issues in GHC's build system because there are sometimes
situations where the package database you need to use is not located in
the same place as the settings file.
* The stage1 compiler needs to use stage1 libraries, so we should set
"Global Package DB" for the stage1 compiler to the stage1 package
database.
* Stage 2 cross compilers need to use stage2 libraries, so likewise, we
should set the package database path to `_build/stage2/lib/`
* The normal situation is where the stage2 compiler uses stage1
libraries. Then everything lines up.
* When installing we have rearranged everything so that the settings
file and package database line up properly, so then everything should
continue to work as before. In this case we set the relative package
db path to `package.conf.d`, so it resolves the same as before.
* ghc-pkg needs to be modified as well to look in the settings file fo
the package database rather than assuming the global package database
location relative to the lib folder.
* Cabal/cabal-install will work correctly because they query the global
package database using `--print-global-package-db`.
A reasonable question is why not generate the "right" settings files in
the right places in GHC's build system. In order to do this you would
need to engineer wrappers for all executables to point to a specific
libdir. There are also situations where the same package db is used by
two different compilers with two different settings files (think stage2
cross compiler and stage3 compiler).
In short, this 10 line patch allows for some reasonable simplifications
in Hadrian at very little cost to anything else.

Don't use bigNatFromWord#, because that's terrible:
* We shouldn't have to traverse a linked list at run-time
to build a BigNat# literal. That's just silly!
* The static List object we have to create is much larger
than the actual BigNat#'s contents, bloating code size.
* We have to read the corresponding interface file,
which causes un-tracked implicit dependencies. (#23942)
Instead, encode them into the appropriate platform-dependent
sequence of bytes, and generate code that copies these bytes
at run-time from an Addr# literal into a new ByteArray#.
A ByteArray# literal would be the correct thing to generate,
but these are not yet supported; see also #17747.
Somewhat surprisingly, this change results in a slight
reduction in compiler allocations, averaging around 0.5%
on ghc's compiler performance tests, including when compiling
programs that contain no bignum literals to begin with.
The specific cause of this has not been investigated.
Since this lowering no longer reads the interface file for
GHC.Num.BigNat, the reasoning in Note [Depend on GHC.Num.Integer]
is obsoleted. But the story of un-tracked built-in dependencies
remains complex, and Note [Tracking dependencies on primitives]
now exists to explain this complexity.
Additionally, many empty imports have been modified to refer to
this new note and comply with its guidance. Several empty imports
necessary for other reasons have also been given brief explanations.

Heap analysis showed that `IfaceTyCon` retains a thunk to
`IfaceTyConInfo`, defeating the sharing of the most common instances of
`IfaceTyConInfo`.
We make sure the indirection is removed by adding bang patterns to
`IfaceTyCon`.
Experimental results on the agda code base, where the `mi_extra_decls`
were read from disk:
Before this change, we observe around 8654045 instances of:
`IfaceTyCon[Name,THUNK_1_0]`
But these thunks almost exclusively point to a shared value!
Forcing the thunk a little bit more, leads to `ghc-debug` reporting:
`IfaceTyCon[Name:Name,IfaceTyConInfo]`
and a noticeable reduction of live bytes (on agda ~10%).

In #24563, we identified that IfaceAppArgs serialisation tags each
cons cell element with a discriminator byte. These bytes add up
quickly, blowing up interface files considerably when
'-fwrite-if-simplified-core' is enabled.
We compact the serialisation by writing out the length of
'IfaceAppArgs', followed by serialising the elements directly without
any discriminator byte.
This improvement can decrease the size of some interface files by up
to 35%.

In #24551, we abstracted a string literal binding over a type variable,
triggering a CoreLint error when that binding floated to top-level.
The solution implemented in this patch fixes this by re-doing dependency
analysis on a simplified recursive let binding that is about to be type
abstracted, in order to find the minimal set of type variables to abstract over.
See wrinkle (AB5) of Note [Floating and type abstraction] for more details.

A user may configure `LDFLAGS` but not `LD`. When choosing a linker, we
will prefer `ldd`, then `ld.gold`, then `ld.bfd` -- however, we have to
check for a working linker. If either of these fail, we try the next in
line.
However, we were not considering the `$LDFLAGS` when checking if these
linkers worked. So we would pick a linker that does not support the
current $LDFLAGS and fail further down the line when we used that linker
with those flags.
Fixes #24565, where `LDFLAGS=-Wl,-z,pack-relative-relocs` is not
supported by `ld.gold` but that was being picked still.

For issue #21506, we started cleaning the extended attributes of
binaries and libraries from the bindist *after* they were installed to
workaround notarisation (#17418), as part of `make install`.
However, the `ghc-toolchain` binary that is now shipped with the bindist
must be run at `./configure` time. Since we only cleaned the xattributes
of the binaries and libs after they were installed, in some situations
users would be unable to run `ghc-toolchain` from the bindist, failing
at configure time (#24554).
In this commit we move the xattr cleaning logic to the configure script.
Fixes #24554
