Lowercase windows imports
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.

Hadrian: Fix problem with unlit path in settings file
e529c65e introduced a problem in the logic for generating the
path to the unlit command in the settings file, and this patches
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.
This addresses #16659.

Fix padding of entries in .prof files
When the number of entries of a cost centre reaches 11 digits, it takes
up the whole space reserved for it and the prof file ends up looking
like:
... no. entries %time %alloc %time %alloc
...
... 120918 978250 0.0 0.0 0.0 0.0
... 118891 0 0.0 0.0 73.3 80.8
... 11890229702412351 8.9 13.5 73.3 80.8
... 118903 153799689 0.0 0.1 0.0 0.1
...
This results in tooling not being able to parse the .prof file. I
realise we have the JSON output as well now, but still it'd be good to
fix this little weirdness.
Original bug report and full prof file can be seen here:

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.

Fix missing unboxed tuple RuntimeReps (#16565)
Unboxed tuples and sums take extra RuntimeRep arguments,
which must be manually passed in a few places.
This was not done in deSugar/Check.
This error was hidden because zipping functions in TyCoRep
ignored lists with mismatching length. This is now fixed;
the lengths are now checked by calling zipEqual.
As suggested in #16565, I moved checking for isTyVar and
isCoVar to zipTyEnv and zipCoEnv.

Allow using tagetContents for modules needing preprocessing
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.

downsweep: Allow TargetFile not to exist when a buffer is given
Currently 'getRootSummary' will fail with an exception if a 'TargetFile' is
given but it does not exist even if an input buffer is passed along for
this target.
In this case it is not necessary for the file to exist since the buffer
will be used as input for the compilation pipeline instead of the file
anyways.

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.

bfccd832 by John Ericson at 2019-05-29T20:06:45Z
Inline `Settings` into `DynFlags`
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.

Hadrian: always generate the libffi dynlibs manifest with globbing
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.

rts: Handle zero-sized mappings in MachO linker
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.

Use binary search to speedup checkUnload
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.

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.

Catch preprocessor errors in downsweep
This changes the way preprocessor failures are presented to the
user. Previously the user would simply get an unlocated message on stderr
such as:
`gcc' failed in phase `C pre-processor'. (Exit code: 1)
Now at the problematic source file is mentioned:
A.hs:1:1: error:
`gcc' failed in phase `C pre-processor'. (Exit code: 1)
This also makes live easier for GHC API clients as the preprocessor error
is now thrown as a SourceError exception.

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.

Fix rewriting invalid shifts to errors
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.

Add `-haddock` option under ci condition to fix #16415
In order to use the `:doc` command in ghci, it is necessary
to compile for core libraries with `-haddock` option.
Especially, the `-haddock` option is essential for release building.
Note:
* The `-haddock` option may affect compile time and binary size.
* But hadrian has already set `-haddock` as the default.
* This patch affects the make-based building.
This patch has been split from !532.

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.

TestRunner: Added --chart to display a chart of performance tests
This uses the Chart.js javascript library.
Everything is put into a standalone .html file and opened with the
default browser.
I also simplified the text output to use the same data as the chart.
You can now use a commit range with git's ".." syntax.
The --ci option will use results from CI (you'll need to fetch them
first):
$ git fetch https://gitlab.haskell.org/ghc/ghc-performance-notes.git refs/notes/perf:refs/notes/ci/perf
$ python3 testsuite/driver/perf_notes.py --ci --chart --test-env x86_64-darwin --test-name T9630 master~500..master

Use a better strategy for determining the offset applied to foreign function arguments that have an unlifted boxed type. We used to use the type of the argument. We now use the type of the foreign function. Add a test to confirm that the roundtrip conversion between an unlifted boxed type and Any is sound in the presence of a foreign function call.

Hadrian: fix OSX build failure and add an OSX/Hadrian CI job
The OSX build failure introduced in 3aa71a22 was due to a change in the
glob we use to collect libffi shared libraries in hadrian/src/Rules/Libffi.hs.
This commit fixes the problem and adds an OSX CI job that builds GHC with
Hadrian, to make sure we don't break it again.

This commit adds the `:instances` command to ghci following proosal

This makes it possible to query which instances are available to a given
type.
The output of this command is all the possible instances with type
variables and constraints instantiated.

[skip ci] Improve the documentation of the CNF primops. In this context, the term "size" is ambiguous and is now avoided. Additionally, the distinction between a CNF and the blocks that comprise it has been emphasize. The vocabulary has been made more consistent with the vocabulary in the C source for CNF.

TmOracle: Replace negative term equalities by refutable PmAltCons
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.

Factor out 'getLibDir' / 'getBaseDir' into a new GHC.BaseDir ghc-boot module
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.

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.
