The binutils documentation (for COFF) claims,
> If no flags are specified, the default flags depend upon the section
> name. If the section name is not recognized, the default will be for the
> section to be loaded and writable.
We previously assumed that this would do the right thing for split
sections (e.g. a section named `.text$foo` would be correctly inferred
to be a text section). However, we have observed that this is not the
case (at least under the clang toolchain used on Windows): when
split-sections is enabled, text sections are treated by the assembler as
data (matching the "default" behavior specified by the documentation).
Avoid this by setting section flags explicitly. This should fix split
sections on Windows.
Fixes #22834.

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,
the same way as we do in rts/rts.cabal.

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.

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`,

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.
See #23550 for more discussion.

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.

8168b42a "Whitespace-sensitive bang patterns" allows GHC to accept
the following infix operators:
a ~ b = ()
a @ b = ()
But not if TH is used to generate those declarations:
$([d| a ~ b = ()
a @ b = ()
|])
-- Test.hs:5:2: error: [GHC-55017]
-- Illegal variable name: ‘~’
-- When splicing a TH declaration: (~_0) a_1 b_2 = GHC.Tuple.Prim.()
This is easily fixed by modifying `reservedOps` in GHC.Utils.Lexeme

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

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.)

The Simplifier had a function `simplArg` that wasn't called in `rebuildCall`,

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

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.
Closes #23689

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.

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.

* FP_INSTALL_WINDOWS_TOOLCHAIN - deals with downloading the toolchain if

* 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

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

we would bundle the whole Avail (C, T, meth) with all of C, T and meth,
instead of only with C.

T8095 ghc/alloc decreased on x86_64, but increased on aarch64.
T13386 ghc/alloc decreased on x86_64-windows, but increased on other platforms.
Neither has anything to do with `foldl'`, so I conclude that both are flaky.

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

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.

Right now, output is squashed. This make per-package configure scripts
extremely hard to maintain, because we get vague "library is missing"
errors when the actually probably is usually completely unrelated except
for also involving the C/C++ toolchain.
(I can always pass `-VVV` to Hadrian locally, but these errors are
subtle and I often cannot reproduce them locally!)
`--disable-option-checking` was added back in
75c6e0684dda585c37b4ac254cd7a13537a59a91 but seems to be a bit overkill;
if other flags are passed that are not recognized behind the two from
Cabal mentioned in the former comment, we *do* want to know about it.

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

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

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:
hadrian/build test --only="codes"

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

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.

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

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

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

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

`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`.
