<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add a safeguard to Core Lint
Lint returns a pair (Maybe a, WarnsAndErrs). The Maybe monad
allows to handle an unrecoverable failure.
In case of such a failure, the error should be added to the second
component of the pair. If this is not done, Lint will silently
accept bad programs. This situation actually happened during
development of linear types. This adds a safeguard.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">GHCi: fix load order of .ghci files
Directives in .ghci files in the current directory ("local .ghci")
can be overridden by global files. Change the order in which the
configs are loaded: global and $HOME/.ghci first, then local.
Also introduce a new field to GHCiState to control whether local
.ghci gets sourced or ignored. This commit does not add a way to
set this value (a subsequent commit will add this), but the .ghci
sourcing routine respects its value.

directive can be set in global config or $HOME/.ghci, which are

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.

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.

Now that `TExp` accepts unlifted types, #16384 is fixed. Since the real

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.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Stop misusing EWildPat in pattern match coverage checking
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
4. Don't perform the W/W split when doing so would eta expand a binding.
Otherwise we would eta expand PAPs, causing unnecessary churn in the

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.

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.

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.

on the .rst files only for now.
We eventually might want to rebuild docs when we, say, change the haddock style

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.

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).

<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

Libffi is ultimately built from a single archive file (e.g.
libffi-tarballs/libffi-3.99999+git20171002+77e130c.tar.gz).
The file can be seen as the shallow dependency for the whole
libffi build. Hence, in all libffi rules, the archive is
`need`ed and the build directory is `trackAllow`ed.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Let the specialiser work on dicts under lambdas
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.

While windows and macOS are currently on case-insensitive file
systems, this poses no issue on those. When cross compiling from
linux with a case sensitive file system and mingw providing only
lowercase headers, this in fact produces an issue. As such we just
lowercase the import headers, which should still work fine on a
case insensitive file system and also enable mingw's headers to
be usable porperly.

e529c65e introduced a problem in the logic for generating the

fixes it.
This fixes many tests, the simplest of which is:
> _build/stage1/bin/ghc testsuite/tests/parser/should_fail/T8430.lhs
which failed because of a wrong path for unlit, and now fails for the right
reason, with the error message expected for this test.

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 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.

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.

As noted in #16701, it is possible that we will find that an object has
no segments needing to be mapped. Previously this would result in mmap
being called for a zero-length mapping, which would fail. We now simply
skip the mmap call in this case; the rest of the logic just works.

We are iterating through all object code for each heap objects when
checking whether object code can be unloaded. For large projects in
GHCi, this can be very expensive due to the large number of object code
that needs to be loaded/unloaded. To speed it up, this arrangess all
mapped sections of unloaded object code in a sorted array and use binary
search to check if an address location fall on them.

<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.

Previously if we had

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.

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.

* This patch affects the make-based building.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add `-haddock` to perf.mk rather than prepare-system.sh
To cover ci conditions from ghc8.6 to 8.9, I add `-haddock` option
to `mk/flavours/perf.mk` rather than `.circleci/prepare-system.sh`.
Because in windows condition of ghc-8.9, `mk/flavours/*` is included
after `prepare-system.sh`.
In addition, in linux condition of ghc-8.6, `mk/flavors/perf.mk` is used.
