<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">testsuite/plugins: Add multi_cpu_race modifier on Windows
A few tests previously failed with various failure modes. For instance,
`plugin-recomp-change` fails with:
```
Wrong exit code for plugin-recomp-change()(expected 0 , actual 2 )
Stderr ( plugin-recomp-change ):
Simple Plugin Passes Queried
Got options:
Simple Plugin Pass Run
C://GitLabRunner//builds//8fc0e283//0//ghc//ghc//inplace//mingw//bin/ld.exe: cannot find -lHSplugin-recompilation-0.1-CPeObcGoBuvHdwBnpK9jQq
collect2.exe: error: ld returned 1 exit status
`gcc.exe' failed in phase `Linker'. (Exit code: 1)
make[2]: *** [Makefile:112: plugin-recomp-change] Error 1
*** unexpected failure for plugin-recomp-change(normal)
```
It's unclear whether the ghc-pkg concurrency issue mentioned in all.T is
the culprit but the set of tests that fail overlaps strongly with the
set of tests that lack the `multi_cpu_race` modifier. Let's see if
adding it fixes them.

commits. The `validate-x86_64-linux-deb9` build will generally catch a
subset of issues caught by `validate-x86_64-linux-deb9-debug` so only
the latter should be in `build`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Reject nested predicates in impredicativity checking
When GHC attempts to unify a metavariable with a type containing
foralls, it will be rejected as an occurrence of impredicativity.
GHC was /not/ extending the same treatment to predicate types, such
as in the following (erroneous) example from #11514:
```haskell
foo :: forall a. (Show a => a -> a) -> ()
foo = undefined
```
This will attempt to instantiate `undefined` at
`(Show a => a -> a) -> ()`, which is impredicative. This patch
catches impredicativity arising from predicates in this fashion.
Since GHC is pickier about impredicative instantiations, some test
cases needed to be updated to be updated so as not to fall afoul of
the new validity check. (There were a surprising number of
impredicative uses of `undefined`!) Moreover, the `T14828` test case
now has slightly less informative types shown with `:print`. This is
due to a a much deeper issue with the GHCi debugger (see #14828).
Fixes #11514.

We use Cabal to parse, configure, register and copy packages, which are
expensive operations that are currently not visible to Shake's profiling
infrastructure. By using `traced` we tell Shake to add these IO actions
to the profiling report, helping us to identify performance bottlenecks.
We use short tracing keys, as recommended in Shake docs: the name of the
current target is already available in the rest of the profiling
information.

splitSections :: Flavour -> Flavour

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Visibility: handle multiple units with the same name
Fixes #16228. The included test case is adapted from the reproduction in
the issue, and fails without this patch.
------
We compute an initial visilibity mapping for units based on what is
present in the package databases. To seed this, we compute a set of all
the package configs to add visibilities for.
However, this set was keyed off the unit's *package name*. This is
correct, since we compare packages across databases by version. However,
we would only ever consider a single, most-preferable unit from the
database in which it was found.
The effect of this was that only one of the libraries in a Cabal package
would be added to this initial set. This would cause attempts to use
modules from the omitted libraries to fail, claiming that the package
was hidden (even though `ghc-pkg` would correctly show it as visible).
A solution is to do the selection of the most preferable packages
separately, and then be sure to consider exposing all units in the
same package in the same package db. We can do this by picking a
most-preferable unit for each package name, and then considering
exposing all units that are equi-preferable with that unit.
------
Why wasn't this bug apparent to all people trying to use sub-libraries
in Cabal? The answer is that Cabal explicitly passes `-package` and
`-package-id` flags for all the packages it wants to use, rather than
relying on the state of the package database. So this bug only really
affects people who are trying to use package databases produced by Cabal
outside of Cabal itself.
One particular example of this is the way that the
Nixpkgs Haskell infrastructure provides wrapped GHCs: typically these
are equipped with a package database containing all the needed
package dependencies, and the user is not expected to pass
`-package` flags explicitly.

- Adds a couple of annotations to `allocateMightFail` indicating which
branches are likely to be taken.
Together this gives about 5% improvement.

Previously, when needing ghc as a builder, the ghcDeps (Files
the GHC binary depends on) for the current stage were needed.
This is incorrect as the previous stage's ghc is used for building.
This commit fixes the issue, needing the previous stage's ghcDeps.

`substBndr` should rename bindings which shadow existing ids.
However while it was renaming the bindings it was not adding proper substitutions
for renamed bindings.
Instead of adding a substitution of the form `old -> new` for renamed
bindings it mistakenly added `old -> old` if no replacement had taken
place while adding none if `old` had been renamed.
As a byproduct this should improve performance, as we no longer add
useless substitutions for unshadowed bindings.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Inline the definition of 'ap' in the Monad laws
The law as it is currently written is meaningless, because nowhere have
we defined the implementation of 'ap'. The reader of the Control.Monad
documentation is provided with only a type signature,
> ap :: Monad m => m (a -> b) -> m a -> m b
an informal description,
> In many situations, the liftM operations can be replaced by uses of
> ap, which promotes function application.
and a relationship between 'ap' and the 'liftM' functions
> return f `ap` x1 `ap` ... `ap` xn
> is equivalent to
> liftMn f x1 x2 ... xn
Without knowing how 'ap' is defined, a law involving 'ap' cannot
provide any guidance for how to write a lawful Monad instance, nor can
we conclude anything from the law.
I suspect that a reader equipped with the understanding that 'ap' was
defined prior to the invention of the Applicative class could deduce
that 'ap' must be defined in terms of (>>=), but nowhere as far as I can
tell have we written this down explicitly for readers without the
benefit of historical context.
If the law is meant to express a relationship among (<*>), (>>=), and
'return', it seems that it is better off making this statement directly,
sidestepping 'ap' altogether.

This fixes #16440, where the build system incorrectly concluded that the
`.subsections_via_symbols` assembler directive was supported on a Linux
system. This was caused by the fact that gcc was invoked with `-flto`;
when so-configured gcc does not call the assembler but rather simply
serialises its AST for compilation during the final link.
This is described in Note [autoconf assembler checks and -flto].

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix Uncovered set of literal patterns
Issues #16289 and #15713 are proof that the pattern match checker did
an unsound job of estimating the value set abstraction corresponding to
the uncovered set.
The reason is that the fix from #11303 introducing `NLit` was
incomplete: The `LitCon` case desugared to `Var` rather than `LitVar`,
which would have done the necessary case splitting analogous to the
`ConVar` case.
This patch rectifies that by introducing the fresh unification variable
in `LitCon` in value abstraction position rather than pattern postition,
recording a constraint equating it to the constructor expression rather
than the literal. Fixes #16289 and #15713.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16518 with some more kind-splitting smarts
This patch corrects two simple oversights that led to #16518:
1. `HsUtils.typeToLHsType` was taking visibility into account in the
`TyConApp` case, but not the `AppTy` case. I've factored out the
visibility-related logic into its own `go_app` function and now
invoke `go_app` from both the `TyConApp` and `AppTy` cases.
2. `Type.fun_kind_arg_flags` did not properly split kinds with
nested `forall`s, such as
`(forall k. k -> Type) -> (forall k. k -> Type)`. This was simply
because `fun_kind_arg_flags`'s `FunTy` case always bailed out and
assumed all subsequent arguments were `Required`, which clearly
isn't the case for nested `forall`s. I tweaked the `FunTy` case
to recur on the result kind.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Tweak error messages for narrowly-kinded assoc default decls
This program, from #13971, currently has a rather confusing error
message:
```hs
class C a where
type T a :: k
type T a = Int
```
```
• Kind mis-match on LHS of default declaration for ‘T’
• In the default type instance declaration for ‘T’
In the class declaration for ‘C’
```
It's not at all obvious why GHC is complaining about the LHS until
you realize that the default, when printed with
`-fprint-explicit-kinds`, is actually `type T @{k} @* a = Int`.
That is to say, the kind of `a` is being instantiated to `Type`,
whereas it ought to be a kind variable. The primary thrust of this
patch is to weak the error message to make this connection
more obvious:
```
• Illegal argument ‘*’ in:
‘type T @{k} @* a = Int’
The arguments to ‘T’ must all be type variables
• In the default type instance declaration for ‘T’
In the class declaration for ‘C’
```
Along the way, I performed some code cleanup suggested by @rae in
https://gitlab.haskell.org/ghc/ghc/issues/13971#note_191287. Before,
we were creating a substitution from the default declaration's type
variables to the type family tycon's type variables by way of
`tcMatchTys`. But this is overkill, since we already know (from the
aforementioned validity checking) that all the arguments in a default
declaration must be type variables anyway. Therefore, creating the
substitution is as simple as using `zipTvSubst`. I took the
opportunity to perform this refactoring while I was in town.
Fixes #13971.

GHC has an optimization for allocating arrays when the size is
statically known -- it'll generate the code allocating and initializing
the array inline (instead of a call to a procedure from
`rts/PrimOps.cmm`).
However, the generated code uses a loop to do the initialization. Since
we already check that the requested size is small (we check against
`maxInlineAllocSize`), we can generate faster straightline code instead.
This brings about 15% improvement for `newSmallArray#` in my testing and
slightly simplifies the code in GHC.

Previously, `singleConstructor` didn't handle singleton `COMPLETE` sets

in #15753.
This is fixed by making `singleConstructor` (now named
`singleMatchConstructor`) query `allCompleteMatches`, necessarily making
it effectful. As a result, most of this patch is concerned with
threading the side-effect through to `singleMatchConstructor`.
Unfortunately, this is not enough to completely fix the original

applications in pattern guards being translated too conservatively.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">codegen: fix memset unroll for small bytearrays, add 64-bit sets
Fixes #16052
When the offset in `setByteArray#` is statically known, we can provide
better alignment guarantees then just 1 byte.
Also, memset can now do 64-bit wide sets.
The current memset intrinsic is not optimal however and can be
improved for the case when we know that we deal with
(baseAddress at known alignment) + offset
For instance, on 64-bit
`setByteArray# s 1# 23# 0#`
given that bytearray is 8 bytes aligned could be unrolled into
`movb, movw, movl, movq, movq`; but currently it is
`movb x23` since alignment of 1 is all we can embed into MO_Memset op.

GHC now works out-of-the-box (i.e. without any wrapper script) by
assuming that @bin@ and @lib@ directories sit next to each other. In
particular, its RUNPATH uses $ORIGIN-based relative path to find the
libraries.
However, to be good citizens we want to support the case where @bin@ and
@lib@ directories (respectively BINDIR and LIBDIR) don't sit next to
each other or are renamed. To do that the install script simply creates
GHC specific @bin@ and @lib@ siblings directories into:
LIBDIR/ghc-VERSION/{bin,lib}
Then it installs wrapper scripts into BINDIR that call the appropriate
programs into LIBDIR/ghc-VERSION/bin/.
The issue fixed by this patch is that libraries were not installed into
LIBDIR/ghc-VERSION/lib but directly into LIBDIR.

* simplifies registers to have GPR, Float and Double, by removing the SSE2 and X87 Constructors
* makes -msse2 assumed/default for x86 platforms, fixing a long standing nondeterminism in rounding
behavior in 32bit haskell code
* removes the 80bit floating point representation from the supported float sizes
* theres still 1 tiny bit of x87 support needed,
for handling float and double return values in FFI calls wrt the C ABI on x86_32,
but this one piece does not leak into the rest of NCG.
* Lots of code thats not been touched in a long time got deleted as a
consequence of all of this
all in all, this change paves the way towards a lot of future further
improvements in how GHC handles floating point computations, along with
making the native code gen more accessible to a larger pool of contributors.

When -a or --test-accept is passed, and if one runs the 'test' target, then
any test failing because of mismatching output and which is not expected to
fail will have its expected output adjusted by the test driver, effectively
considering the new output correct from now on.
When this flag is passed, hadrian's 'test' target becomes sensitive to the
PLATFORM and OS environment variable, just like the Make build system:
- when the PLATFORM env var is set to "YES", when accepting a result, accept it
for the current platform;
- when the OS env var is set to "YES", when accepting a result, accept it
for all wordsizes of the current operating system.
This can all be combined with `--only="..."` and `TEST="..." to only accept
the new output of a subset of tests.

When a new closure identifier is being established to a
local or exported closure already emitted into the same
module, refrain from adding an IND_STATIC closure, and
instead emit an assembly-language alias.
Inter-module IND_STATIC objects still remain, and need to be
addressed by other measures.
Binary-size savings on nofib are around 0.1%.

Besides the obvious benefits of being able to manipulate `TExp`'s of
unboxed types, this also simplified `-XDeriveLift` all while making
it more capable.
* `ghc-prim` is explicitly depended upon by `template-haskell`
* The following TH things are parametrized over `RuntimeRep`:
- `TExp(..)`
- `unTypeQ`
- `unsafeTExpCoerce`
- `Lift(..)`
* The following instances have been added to `Lift`:
- `Int#`, `Word#`, `Float#`, `Double#`, `Char#`, `Addr#`
- unboxed tuples of lifted types up to arity 7
- unboxed sums of lifted types up to arity 7
Ideally we would have levity-polymorphic _instances_ of unboxed
tuples and sums.
* The code generated by `-XDeriveLift` uses expression quotes
instead of generating large amounts of TH code and having
special hard-coded cases for some unboxed types.

Previously we would generate a local variable pointing after the array
header and use it to initialize the array elements. But we already use
stores with offset, so it's easy to just add the header to those offsets
during compilation and avoid generating the local variable (which would
become a LEA instruction when using native codegen; LLVM already
optimizes it away).

4 haddock tests assume that .haddock files have been produced, by using the
'req_haddock' modifier. The testsuite driver assumes that this condition is
satisfied if 'config.haddock' is non-empty, but before this patch Hadrian was
always passing the path to where the haddock executable should be, regardless
of whether it is actually there or not.
Instead, we now pass an empty config.haddock when we can't find all of
<build root>/docs/html/libraries/<pkg>/<pkg>.haddock>, where <pkg> ranges over
array, base, ghc-prim, process and template-haskell, and pass the path
to haddock when all those file exists. This has the (desired) effect of skipping
the 4 tests (marked as 'missing library') when the docs haven't been built,
and running the haddock tests when they have.

EWildPat is a constructor of HsExpr used in the parser to represent
wildcards in ambiguous positions:
* in expression context, EWildPat is turned into hsHoleExpr (see rnExpr)
* in pattern context, EWildPat is turned into WildPat (see checkPattern)
Since EWildPat exists solely for the needs of the parser, we could
remove it by improving the parser.
However, EWildPat has also been used for a different purpose since
8a50610: to represent patterns that the coverage checker cannot handle.
Not only this is a misuse of EWildPat, it also stymies the removal of
EWildPat.

3. Remove the special case for trivial RHSs, which is subsumed by 2

The bulk of the work was done in #712, making settings be make/Hadrian
controlled. This commit then just moves the unlit command rules in
make/Hadrian from the `Config.hs` generator to the `settings` generator
in each build system.
I think this is a good change because the crucial benefit is *settings*
don't affect the build: ghc gets one baby step closer to being a regular
cabal executable, and make/Hadrian just maintains settings as part of
bootstrapping.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Pattern/expression ambiguity resolution
This patch removes 'EWildPat', 'EAsPat', 'EViewPat', and 'ELazyPat'
from 'HsExpr' by using the ambiguity resolution system introduced
earlier for the command/expression ambiguity.
Problem: there are places in the grammar where we do not know whether we
are parsing an expression or a pattern, for example:
do { Con a b <- x } -- 'Con a b' is a pattern
do { Con a b } -- 'Con a b' is an expression
Until we encounter binding syntax (<-) we don't know whether to parse
'Con a b' as an expression or a pattern.
The old solution was to parse as HsExpr always, and rejig later:
checkPattern :: LHsExpr GhcPs -> P (LPat GhcPs)
This meant polluting 'HsExpr' with pattern-related constructors. In
other words, limitations of the parser were affecting the AST, and all
other code (the renamer, the typechecker) had to deal with these extra
constructors.
We fix this abstraction leak by parsing into an overloaded
representation:
class DisambECP b where ...
newtype ECP = ECP { runECP_PV :: forall b. DisambECP b => PV (Located b) }
See Note [Ambiguous syntactic categories] for details.
Now the intricacies of parsing have no effect on the hsSyn AST when it
comes to the expression/pattern ambiguity.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make equality constraints in kinds invisible
Issues #12102 and #15872 revealed something strange about the way GHC
handles equality constraints in kinds: it treats them as _visible_
arguments! This causes a litany of strange effects, from strange
error messages
(https://gitlab.haskell.org/ghc/ghc/issues/12102#note_169035)
to bizarre `Eq#`-related things leaking through to GHCi output, even
without any special flags enabled.
This patch is an attempt to contain some of this strangeness.
In particular:
* In `TcHsType.etaExpandAlgTyCon`, we propagate through the
`AnonArgFlag`s of any `Anon` binders. Previously, we were always
hard-coding them to `VisArg`, which meant that invisible binders
(like those whose kinds were equality constraint) would mistakenly
get flagged as visible.
* In `ToIface.toIfaceAppArgsX`, we previously assumed that the
argument to a `FunTy` always corresponding to a `Required`
argument. We now dispatch on the `FunTy`'s `AnonArgFlag` and map
`VisArg` to `Required` and `InvisArg` to `Inferred`. As a
consequence, the iface pretty-printer correctly recognizes that
equality coercions are inferred arguments, and as a result,
only displays them in `-fprint-explicit-kinds` is enabled.
* Speaking of iface pretty-printing, `Anon InvisArg` binders were
previously being pretty-printed like `T (a :: b ~ c)`, as if they
were required. This seemed inconsistent with other invisible
arguments (that are printed like `T @{d}`), so I decided to switch
this to `T @{a :: b ~ c}`.
Along the way, I also cleaned up a minor inaccuracy in the users'
guide section for constraints in kinds that was spotted in
https://gitlab.haskell.org/ghc/ghc/issues/12102#note_136220.
Fixes #12102 and #15872.

to point to '<build root>/test/ghcconfig' instead, which is where we
always put the test config.
Previously, we would build ghc-config and run it against the
GHC to be tested, a second time, while we're running the tests, because some
include testsuite/mk/boilerplate.mk. This was causing unexpected output
failures.

As of commit d37d91e9a444a7822eef1558198d21511558515e, the GHC build
now autogenerates a `includes/dist/build/settings` file. To avoid
dirtying the current `git` status, this adds `includes/dist` to
`.gitignore`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Check for duplicate variables in associated default equations
A follow-up to !696's, which attempted to clean up the error messages
for ill formed associated type family default equations. The previous
attempt, !696, forgot to account for the possibility of duplicate
kind variable arguments, as in the following example:
```hs
class C (a :: j) where
type T (a :: j) (b :: k)
type T (a :: k) (b :: k) = k
```
This patch addresses this shortcoming by adding an additional check
for this. Fixes #13971 (hopefully for good this time).

1. If GHC is to be multi-target, these cannot be baked in at compile
time.
2. Compile-time flags have a higher maintenance than run-time flags.
3. The old way makes build system implementation (various bootstrapping
details) with the thing being built. E.g. GHC doesn't need to care
about which integer library *will* be used---this is purely a crutch
so the build system doesn't need to pass flags later when using that
library.
4. Experience with cross compilation in Nixpkgs has shown things work
nicer when compiler's can *optionally* delegate the bootstrapping the
package manager. The package manager knows the entire end-goal build
plan, and thus can make top-down decisions on bootstrapping. GHC can
just worry about GHC, not even core library like base and ghc-prim!

GHC Proposal #36 describes a transition plan away from CUSKs and to
top-level kind signatures:
1. Introduce a new extension, -XCUSKs, on by default, that detects CUSKs
as they currently exist.
2. We turn off the -XCUSKs extension in a few releases and remove it
sometime thereafter.
This patch implements phase 1 of this plan, introducing a new language
extension to control whether CUSKs are enabled. When top-level kind
signatures are implemented, we can transition to phase 2.

Most places where we convert contexts in `Convert` are actually in
positions that are to the left of some `=>`, such as in superclasses
and instance contexts. Accordingly, these contexts need to be
parenthesized at `funPrec`. To accomplish this, this patch changes
`cvtContext` to require a precedence argument for the purposes of
calling `parenthesizeHsContext` and adjusts all `cvtContext` call
sites accordingly.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Have GHCi use object code for UnboxedTuples modules #15454
The idea is to automatically enable -fobject-code for modules that use
UnboxedTuples, along with all the modules they depend on. When looking
into how to solve this, I was pleased to find that there was already
highly similar logic for enabling code generation when -fno-code is
specified but TemplateHaskell is used.
The state before this patch was that if you used unboxed tuples then you
had to enable `-fobject-code` globally rather than on a per module
basis.

Commit e75a9afd2989e0460f9b49fa07c1667299d93ee9 added an `unsigned` cast
to account for OSes that have signed `rlim_t` signed. Unfortunately,
the `unsigned` cast has the unintended effect of narrowing `rlim_t` to
only 4 bytes. This leads to some spurious out of memory crashes
(in particular: Haddock crashes with OOM whenn building docs of
`ghc`-the-library).
In this case, `W_` is a better type to cast to: we know it will be
unsigned too and it has the same type as `*len` (so we don't suffer from
accidental narrowing).

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Use HsTyPats in associated type family defaults
Associated type family default declarations behave strangely in a
couple of ways:
1. If one tries to bind the type variables with an explicit `forall`,
the `forall`'d part will simply be ignored. (#16110)
2. One cannot use visible kind application syntax on the left-hand
sides of associated default equations, unlike every other form
of type family equation. (#16356)
Both of these issues have a common solution. Instead of using
`LHsQTyVars` to represent the left-hand side arguments of an
associated default equation, we instead use `HsTyPats`, which is what
other forms of type family equations use. In particular, here are
some highlights of this patch:
* `FamEqn` is no longer parameterized by a `pats` type variable, as
the `feqn_pats` field is now always `HsTyPats`.
* The new design for `FamEqn` in chronicled in
`Note [Type family instance declarations in HsSyn]`.
* `TyFamDefltEqn` now becomes the same thing as `TyFamInstEqn`. This
means that many of `TyFamDefltEqn`'s code paths can now reuse the
code paths for `TyFamInstEqn`, resulting in substantial
simplifications to various parts of the code dealing with
associated type family defaults.
Fixes #16110 and #16356.

When the '--hadrian' flag is passed to the validate script, we use hadrian

testsuite against the said bindist, which gets installed locally in the process.
Along the way, this commit fixes a typo, an omission (build iserv binaries
before producing the bindist archive) and moves the Makefile that enables
'make install' on those bindists from being a list of strings in the code to
an actual file (it was becoming increasingly annoying to work with).
Finally, the Settings.Builders.Ghc part of this patch is necessary for being
able to use the installed binary distribution, in 'validate'.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add PlainPanic for throwing exceptions without depending on pprint
This commit splits out a subset of GhcException which do not depend on
pretty printing (SDoc), as a new datatype called
PlainGhcException. These exceptions can be caught as GhcException,
because 'fromException' will convert them.
The motivation for this change is that that the Panic module
transitively depends on many modules, primarily due to pretty printing
code. It's on the order of about 130 modules. This large set of
dependencies has a few implications:
1. To avoid cycles / use of boot files, these dependencies cannot
throw GhcException.
2. There are some utility modules that use UnboxedTuples and also use
`panic`. This means that when loading GHC into GHCi, about 130
additional modules would need to be compiled instead of
interpreted. Splitting the non-pprint exception throwing into a new
module resolves this issue. See #13101

Following the discussion under #16473, this change allows the
specializer to work on any dicts in a lambda, not just those that occur
at the beginning.
For example, if you use data types which contain dictionaries and
higher-rank functions then once these are erased by the optimiser you
end up with functions such as:
```
go_s4K9
Int#
-> forall (m :: * -> *).
Monad m =>
(forall x. Union '[State (Sum Int)] x -> m x) -> m ()

The dictionary argument is after the Int# value argument, this patch
allows `go` to be specialised.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">testsuite: introduce 'static_stats' tests
They are a particular type of perf tests. This patch introduces a
'stats_files_dir' configuration field in the testsuite driver where all
haddock timing files (and possibly others in the future) are assumed to live.
We also change both the Make and Hadrian build systems to pass respectively
$(TOP)/testsuite/tests/perf/haddock/ and
<build root>/stage1/haddock-timing-files/ as the value of that new
configuration field, and to generate the timing files in those directories
in the first place while generating documentation with haddock.
This new test type can be seen as one dedicated to examining stats files that
are generated while building a GHC distribution. This also lets us get rid of
the 'extra_files' directives in the all.T entries for haddock.base,
haddock.Cabal and haddock.compiler.

This error was hidden because zipping functions in TyCoRep

This allows GHC API clients, most notably tooling such as
Haskell-IDE-Engine, to pass unsaved files to GHC more easily.
Currently when targetContents is used but the module requires preprocessing
'preprocessFile' simply throws an error because the pipeline does not
support passing a buffer.
This change extends `runPipeline` to allow passing the input buffer into
the pipeline. Before proceeding with the actual pipeline loop the input
buffer is immediately written out to a new tempfile.
I briefly considered refactoring the pipeline at large to pass around
in-memory buffers instead of files, but this seems needlessly complicated
since no pipeline stages other than Hsc could really support this at the
moment.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Break up `Settings` into smaller structs
As far as I can tell, the fields within `Settings` aren't *intrinsicly*
related. They just happen to be initialized the same way (in particular
prior to the rest of `DynFlags`), and that is why they are grouped
together.
Within `Settings`, however, there are groups of settings that clearly do
share something in common, regardless of how they anything is
initialized.
In the spirit of GHC being a library, where the end cosumer may choose
to initialize this configuration in arbitrary ways, I made some new data
types for thoses groups internal to `Settings`, and used them to define
`Settings` instead. Hopefully this is a baby step towards a general
decoupling of the stateful and stateless parts of GHC.

After the previous commit, `Settings` is just a thin wrapper around
other groups of settings. While `Settings` is used by GHC-the-executable
to initalize `DynFlags`, in principle another consumer of
GHC-the-library could initialize `DynFlags` a different way. It
therefore doesn't make sense for `DynFlags` itself (library code) to
separate the settings that typically come from `Settings` from the
settings that typically don't.

Instead of trying to deduce which dynlibs are expected to be found (and then
copied to the RTS's build dir) in libffi's build directory, with some OS
specific logic, we now always just use `getDirectoryFilesIO` to look for
those dynlibs and record their names in the manifest. The previous logic
ended up causing problems on Windows, where we don't build dynlibs at all
for now but the manifest file's logic didn't take that into account because
it was only partially reproducing the criterions that determine whether or not
we will be building shared libraries.
This patch also re-enables the Hadrian/Windows CI job, which was failing to
build GHC precisely because of libffi shared libraries and the aforementionned
duplicated logic.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Refactor summarise{File,Module} to extract checkSummaryTimestamp
This introduces a slight change of behaviour in the interrest of keeping
the code simple: Previously summariseModule would not call
addHomeModuleToFinder for summaries that are being re-used but now we do.
We're forced to to do this in summariseFile because the file being
summarised might not even be on the regular search path! So if GHC is to
find it at all we have to pre-populate the cache with its location. For
modules however the finder cache is really just a cache so we don't have to
pre-populate it with the module's location.
As straightforward as that seems I did almost manage to introduce a bug (or
so I thought) because the call to addHomeModuleToFinder I copied from
summariseFile used to use `ms_location old_summary` instead of the
`location` argument to checkSummaryTimestamp. If this call were to
overwrite the existing entry in the cache that would have resulted in us
using the old location of any module even if it was, say, moved to a
different directory between calls to 'depanal'.
However it turns out the cache just ignores the location if the module is
already in the cache. Since summariseModule has to search for the module,
which has the side effect of populating the cache, everything would have
been fine either way.
Well I'm adding a test for this anyways: tests/depanal/OldModLocation.hs.

On powerpc32 64-bit comparison code generated dangling
target labels. This caused ghc build failure as:
$ ./configure --target=powerpc-unknown-linux-gnu && make
...
SCCs aren't in reverse dependent order
bad blockId n3U
This happened because condIntCode' in PPC codegen generated
label name but did not place the label into `cmp_lo` code block.
The change adds the `cmp_lo` label into the case of negative
comparison.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix arity type of coerced types in CoreArity
Previously if we had
f |> co
where `f` had arity type `ABot N` and `co` had arity M and M < N,
`arityType` would return `ABot M` which is wrong, because `f` is only
known to diverge when applied to `N` args, as described in Note
[ArityType]:
If at = ABot n, then (f x1..xn) definitely diverges. Partial
applications to fewer than n args may *or may not* diverge.
This caused incorrect eta expansion in the simplifier, causing #16066.
We now return `ATop M` for the same expression so the simplifier can't
assume partial applications of `f |> co` is divergent.
A regression test T16066 is also added.

Fixes #16449.
5341edf3 removed a code in rewrite rules for bit shifts, which broke the
"silly shift guard", causing generating invalid bit shifts or heap
overflow in compile time while trying to evaluate those invalid bit
shifts.
The "guard" is explained in Note [Guarding against silly shifts] in
PrelRules.hs.
More specifically, this was the breaking change:
--- a/compiler/prelude/PrelRules.hs
+++ b/compiler/prelude/PrelRules.hs
@@ -474,12 +474,11 @@ shiftRule shift_op
; case e1 of
_ | shift_len == 0
-> return e1
- | shift_len < 0 || wordSizeInBits dflags < shift_len
- -> return (mkRuntimeErrorApp rUNTIME_ERROR_ID wordPrimTy
- ("Bad shift length" ++ show shift_len))
This patch reverts this change.
Two new tests added:
- T16449_1: The original reproducer in #16449. This was previously
casing a heap overflow in compile time when CmmOpt tries to evaluate
the large (invalid) bit shift in compile time, using `Integer` as the
result type. Now it builds as expected. We now generate an error for
the shift as expected.
- T16449_2: Tests code generator for large (invalid) bit shifts.

The `PmExprEq` business was a huge hack and was at the same time vastly
too powerful and not powerful enough to encode negative term equalities,
i.e. facts of the form "forall y. x ≁ Just y".
This patch introduces the concept of 'refutable shapes': What matters
for the pattern match checker is being able to encode knowledge of the
kind "x can no longer be the literal 5". We encode this knowledge in a
`PmRefutEnv`, mapping a set of newly introduced `PmAltCon`s (which are
just `PmLit`s at the moment) to each variable denoting above
inequalities.
So, say we have `x ≁ 42 ∈ refuts` in the term oracle context and
try to solve an equality like `x ~ 42`. The entry in the refutable
environment will immediately lead to a contradiction.
This machinery renders the whole `PmExprEq` and `ComplexEq` business
unnecessary, getting rid of a lot of (mostly dead) code.
See the Note [Refutable shapes] in TmOracle for a place to start.

ghc-pkg and ghc already both needed this. I figure it is better to
deduplicate, especially seeing that changes to one (FreeBSD CPP) didn't
make it to the other.
Additionally in !1090 I make ghc-pkg look up the settings file, which
makes it use the top dir a bit more widely. If that lands, any
difference in the way they find the top dir would be more noticable.
That change also means sharing more code between ghc and ghc-package
(namely the settings file parsing code), so I'd think it better to get
off the slipperly slope of duplicating code now.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Preserve ShadowInfo when rewriting evidence
When the canonicaliser rewrites evidence of a Wanted, it
should preserve the ShadowInfo (ctev_nosh) field. That is,
a WDerive should rewrite to WDerive, and WOnly to WOnly.
Previously we were unconditionally making a WDeriv, thereby
rewriting WOnly to WDeriv. This bit Nick Frisby (issue #16735)
in the context of his plugin, but we don't have a compact test
case.
The fix is simple, but does involve a bit more plumbing,
to pass the old ShadowInfo around, to use when building
the new Wanted.

Previously we were passing `--unshallow` to `git fetch` in the linting
rules to ensure that the base commit which we were linting with respect
to was available. However, this breaks due to GitLab's re-use of
working directories since `git fetch --unshallow` fails on a repository
which is not currently shallow.
Given that `git fetch --unshallow` circumvents the efficiencies provided
by shallow clones anyways, let's just disable them entirely.
There is no documented way to do disable shallow clones but on checking
the GitLab implementation it seems that setting `GIT_DEPTH=0` should do
the trick.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16517 by bumping the TcLevel for method sigs
There were actually two bugs fixed here:
1. candidateQTyVarsOfType needs to be careful that it does not
try to zap metavariables from an outer scope as "naughty"
quantification candidates. This commit adds a simple check
to avoid doing so.
2. We weren't bumping the TcLevel in kcHsKindSig, which was used
only for class method sigs. This mistake led to the acceptance
of
class C a where
meth :: forall k. Proxy (a :: k) -> ()
Note that k is *locally* quantified. This patch fixes the
problem by using tcClassSigType, which correctly bumps the
level. It's a bit inefficient because tcClassSigType does other
work, too, but it would be tedious to repeat much of the code
there with only a few changes. This version works well and is
simple.
And, while updating comments, etc., I noticed that tcRnType was
missing a pushTcLevel, leading to #16767, which this patch also
fixes, by bumping the level. In the refactoring here, I also
use solveEqualities. This initially failed ghci/scripts/T15415,
but that was fixed by teaching solveEqualities to respect
-XPartialTypeSignatures.
This patch also cleans up some Notes around error generation that
came up in conversation.

This patch adds two new commands `:enable` and `:disable` to the GHCi debugger.
Opposite to `:set stop <n> :continue` a breakpoint disabled with `:disable` will
not loose its previously set stop command.
A new field breakEnabled is added to the BreakLocation data structure to
track the enable/disable state. When a breakpoint is disabled with a `:disable`
command, the following happens:
The corresponding BreakLocation data element is searched dictionary of the
`breaks` field of the GHCiStateMonad. If the break point is found and not
already in the disabled state, the breakpoint is removed from bytecode.
The BreakLocation data structure is kept in the breaks list and the new
breakEnabled field is set to false.
The `:enable` command works similar.
The breaks field in the GHCiStateMonad was changed from an association list
to int `IntMap`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Remove CPP ensuring word size is 32 or 64 bits around Addr# <-> int# primops
It shouldn't be needed these days, and those primops are "highly
deprecated" anyways.
This fits with my plans because it removes one bit of target-dependence
of the builtin primops, and this is the hardest part of GHC to make
multi-target.

When pop() returns with `*c == NULL` retainerProfile will immediately
return. All other code paths is pop() continue with the next stackElement
when this happens so it seems weird to me that TREC_CHUNK we would suddenly
abort everything even though the stack might still have elements left to

Currently the rule for .hi files just triggers (via need) the rule

Likewise for .o-boot and .hi-boot files. This is a bit of an abuse
of Shake, and in fact shake supports rules with multiple output

This was previously broken in several ways. This is fixed and it also
now tests arrays. Unfortunately I was unable to find a way to continue
testing PAP and FUN sizes; these simply depend too much upon the
behavior of the simplifier.
I also tried to extend this to test non-empty arrays as well but
unfortunately this was non-trivial as the array card size constant isn't
readily available from haskell.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Refine the GHCI macro into HAVE[_{INTERNAL, EXTERNAL}]_INTERPRETER
As discussed in #16331, the GHCI macro, defined through 'ghci' flags
in ghc.cabal.in, ghc-bin.cabal.in and ghci.cabal.in, is supposed to indicate
whether GHC is built with support for an internal interpreter, that runs in
the same process. It is however overloaded in a few places to mean
"there is an interpreter available", regardless of whether it's an internal
or external interpreter.
For the sake of clarity and with the hope of more easily being able to
build stage 1 GHCs with external interpreter support, this patch splits
the previous GHCI macro into 3 different ones:
- HAVE_INTERNAL_INTERPRETER: GHC is built with an internal interpreter
- HAVE_EXTERNAL_INTERPRETER: GHC is built with support for external interpreters
- HAVE_INTERPRETER: HAVE_INTERNAL_INTERPRETER || HAVE_EXTERNAL_INTERPRETER

As discussed in #16744, both the Make and Hadrian build systems
have special code to always pass -eventlog whenever -prof or -debug
are passed. However, there is some similar logic in the RTS itself only
for defining TRACING when the DEBUG macro is defined, but no such logic
is implemented to define TRACING when the PROFILING macro is defined.
This patch adds such a logic and therefore fixes #16744.

Make/shell variable names which contain dashes can cause problems under
some conditions. The 'ghc-config-mk' variable from testsuite/mk/boilerplate.mk
that I made overridable (by Hadrian) in ba0aed2e was working as expected when
our Hadrian/Linux job was based off the deb8 Docker image, but broke when
I switched the job to use our deb9-based image, in 3d97bad6. The exact
circumstances/tool versions that trigger this problem are unknown, but
changing the variable's name to 'ghc_config_mk' lets us work around the issue.
This fixes the annth_compunits and annth_make test failures that showed up
when we switched the Hadrian/Linux job to use the deb9 environment.

`checkUnload` currently doesn't check the info header of static objects.
Thus, it may free an `ObjectCode` struct wrongly even if there's still a
live static object whose info header lies in a mapped section of that
`ObjectCode`. This fixes the issue by adding an appropriate check.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PrelRules: Ensure that string unpack/append rule fires with source notes
Previously the presence of source notes could hide nested applications
of `unpackFoldrCString#` from our constant folding logic. For instance,
consider the expression:
```haskell
unpackFoldrCString# "foo" c (unpackFoldrCString# "baz" c n)
```
Specifically, ticks appearing in two places can defeat the rule:
a. Surrounding the inner application of `unpackFoldrCString#`
b. Surrounding the fold function, `c`
The latter caused the `str_rules` testcase to fail when `base` was built
with `-g3`.
Fixes #16740.
