Disallow constraints in KindSigCtxt
This patch cleans up how `GHC.Tc.Validity` classifies `UserTypeCtxt`s
that can only refer to kind-level positions, which is important for
rejecting certain classes of programs. In particular, this patch:
* Introduces a new `TypeOrKindCtxt` data type and
`typeOrKindCtxt :: UserTypeCtxt -> TypeOrKindCtxt` function, which
determines whether a `UserTypeCtxt` can refer to type-level
contexts, kind-level contexts, or both.
* Defines the existing `allConstraintsAllowed` and `vdqAllowed`
functions in terms of `typeOrKindCtxt`, which avoids code
duplication and ensures that they stay in sync in the future.
The net effect of this patch is that it fixes #18714, in which it was
discovered that `allConstraintsAllowed` incorrectly returned `True`
for `KindSigCtxt`. Because `typeOrKindCtxt` now correctly classifies
`KindSigCtxt` as a kind-level context, this bug no longer occurs.

Better eta-expansion (again) and don't specilise DFuns
This patch fixes #18223, which made GHC generate an exponential
amount of code. There are three quite separate changes in here
1. Re-engineer eta-expansion (again). The eta-expander was
generating lots of intermediate stuff, which could be optimised
away, but which choked the simplifier meanwhile. Relatively
easy to kill it off at source.
See Note [The EtaInfo mechanism] in GHC.Core.Opt.Arity.
The main new thing is the use of pushCoArg in getArg_maybe.
2. Stop Specialise specalising DFuns. This is the cause of a huge
(and utterly unnecessary) blowup in program size in #18223.
See Note [Do not specialise DFuns] in GHC.Core.Opt.Specialise.
I also refactored the Specialise monad a bit... it was silly,
because it passed on unchanging values as if they were mutable
state.
3. Do an extra Simplifer run, after SpecConstra and before
late-Specialise. I found (investigating perf/compiler/T16473)
that failing to do this was crippling *both* SpecConstr *and*
Specialise. See Note [Simplify after SpecConstr] in
GHC.Core.Opt.Pipeline.
This change does mean an extra run of the Simplifier, but only
with -O2, and I think that's acceptable.
T16473 allocates *three* times less with this change. (I changed
it to check runtime rather than compile time.)
Some smaller consequences
* I moved pushCoercion, pushCoArg and friends from SimpleOpt
to Arity, because it was needed by the new etaInfoApp.
And pushCoValArg now returns a MCoercion rather than Coercion for
the argument Coercion.
* A minor, incidental improvement to Core pretty-printing
This does fix #18223, (which was otherwise uncompilable. Hooray. But
there is still a big intermediate because there are some very deeply
nested types in that program.
Modest reductions in compile-time allocation on a couple of benchmarks
T12425 -2.0%
T13253 -10.3%
Metric increase with -O2, due to extra simplifier run
T9233 +5.8%
T12227 +1.8%
T15630 +5.0%
There is a spurious apparent increase on heap residency on T9630,
on some architectures at least. I tried it with -G1 and the residency
is essentially unchanged.

Fix the occurrence analyser
Ticket #18603 demonstrated that the occurrence analyser's
handling of
local RULES for imported Ids
(which I now call IMP-RULES) was inadequate. It led the simplifier
into an infnite loop by failing to label a binder as a loop breaker.
The main change in this commit is to treat IMP-RULES in a simple and
uniform way: as extra rules for the local binder. See
Note [IMP-RULES: local rules for imported functions]
This led to quite a bit of refactoring. The result is still tricky,
but it's much better than before, and better documented I think.
Oh, and it fixes the bug.

PmCheck: Rewrite inhabitation test
We used to produce inhabitants of a pattern-match refinement type Nabla
in the checker in at least two different and mostly redundant ways:
1. There was `provideEvidence` (now called
`generateInhabitingPatterns`) which is used by
`GHC.HsToCore.PmCheck` to produce non-exhaustive patterns, which
produces inhabitants of a Nabla as a sub-refinement type where all
match variables are instantiated.
2. There also was `ensure{,All}Inhabited` (now called
`inhabitationTest`) which worked slightly different, but was
whenever new type constraints or negative term constraints were
added. See below why `provideEvidence` and `ensureAllInhabited`
can't be the same function, the main reason being performance.
3. And last but not least there was the `nonVoid` test, which tested
that a given type was inhabited. We did use this for strict fields
and -XEmptyCase in the past.
The overlap of (3) with (2) was always a major pet peeve of mine. The
latter was quite efficient and proven to work for recursive data types,
etc, but could not handle negative constraints well (e.g. we often want
to know if a *refined* type is empty, such as `{ x:[a] | x /= [] }`).
Lower Your Guards suggested that we could get by with just one, by
replacing both functions with `inhabitationTest` in this patch.
That was only possible by implementing the structure of φ constraints
as in the paper, namely the semantics of φ constructor constraints.
This has a number of benefits:
a. Proper handling of unlifted types and strict fields, fixing #18249,
without any code duplication between
`GHC.HsToCore.PmCheck.Oracle.instCon` (was `mkOneConFull`) and
`GHC.HsToCore.PmCheck.checkGrd`.
b. `instCon` can perform the `nonVoid` test (3) simply by emitting
unliftedness constraints for strict fields.
c. `nonVoid` (3) is thus simply expressed by a call to
`inhabitationTest`.
d. Similarly, `ensureAllInhabited` (2), which we called after adding
type info, now can similarly be expressed as the fuel-based
`inhabitationTest`.
See the new `Note [Why inhabitationTest doesn't call generateInhabitingPatterns]`
why we still have tests (1) and (2).
Fixes #18249 and brings nice metric decreases for `T17836` (-76%) and
`T17836b` (-46%), as well as `T18478` (-8%) at the cost of a few very
minor regressions (< +2%), potentially due to the fact that
`generateInhabitingPatterns` does more work to suggest the minimal
COMPLETE set.

Refactor CLabel pretty-printing
* Don't depend on the selected backend to know if we print Asm or C
labels: we already have PprStyle to determine this. Moreover even when
a native backend is used (NCG, LLVM) we may want to C headers
containing pretty-printed labels, so it wasn't a good predicate
anyway.
* Make pretty-printing code clearer and avoid partiality

Implement Quick Look impredicativity
This patch implements Quick Look impredicativity (#18126), sticking
very closely to the design in
A quick look at impredicativity, Serrano et al, ICFP 2020
The main change is that a big chunk of GHC.Tc.Gen.Expr has been
extracted to two new modules
GHC.Tc.Gen.App
GHC.Tc.Gen.Head
which deal with typechecking n-ary applications, and the head of
such applications, respectively. Both contain a good deal of
documentation.
Three other loosely-related changes are in this patch:
* I implemented (partly by accident) points (2,3)) of the accepted GHC
proposal "Clean up printing of foralls", namely
https://github.com/ghc-proposals/ghc-proposals/blob/
master/proposals/0179-printing-foralls.rst
(see #16320).
In particular, see Note [TcRnExprMode] in GHC.Tc.Module
- :type instantiates /inferred/, but not /specified/, quantifiers
- :type +d instantiates /all/ quantifiers
- :type +v is killed off
That completes the implementation of the proposal,
since point (1) was done in
commit df08468113ab46832b7ac0a7311b608d1b418c4d
Author: Krzysztof Gogolewski <krzysztof.gogolewski at tweag.io>
Date: Mon Feb 3 21:17:11 2020 +0100
Always display inferred variables using braces
* HsRecFld (which the renamer introduces for record field selectors),
is now preserved by the typechecker, rather than being rewritten
back to HsVar. This is more uniform, and turned out to be more
convenient in the new scheme of things.
* The GHCi debugger uses a non-standard unification that allows the
unification variables to unify with polytypes. We used to hack
this by using ImpredicativeTypes, but that doesn't work anymore
so I introduces RuntimeUnkTv. See Note [RuntimeUnkTv] in
GHC.Runtime.Heap.Inspect
Updates haddock submodule.
WARNING: this patch won't validate on its own. It was too
hard to fully disentangle it from the following patch, on
type errors and kind generalisation.
Changes to tests
* Fixes #9730 (test added)
* Fixes #7026 (test added)
* Fixes most of #8808, except function `g2'` which uses a
section (which doesn't play with QL yet -- see #18126)
Test added
* Fixes #1330. NB Church1.hs subsumes Church2.hs, which is now deleted
* Fixes #17332 (test added)
* Fixes #4295
* This patch makes typecheck/should_run/T7861 fail.
But that turns out to be a pre-existing bug: #18467.
So I have just made T7861 into expect_broken(18467)

Improve kind generalisation, error messages
This patch does two things:
* It refactors GHC.Tc.Errors a bit. In debugging Quick Look I was
forced to look in detail at error messages, and ended up doing a bit
of refactoring, esp in mkTyVarEqErr'. It's still quite a mess, but
a bit better, I think.
* It makes a significant improvement to the kind checking of type and
class declarations. Specifically, we now ensure that if kind
checking fails with an unsolved constraint, all the skolems are in
scope. That wasn't the case before, which led to some obscure error
messages; and occasional failures with "no skolem info" (eg #16245).
Both of these, and the main Quick Look patch itself, affect a /lot/ of
error messages, as you can see from the number of files changed. I've
checked them all; I think they are as good or better than before.
Smaller things
* I documented the various instances of VarBndr better.
See Note [The VarBndr tyep and its uses] in GHC.Types.Var
* Renamed GHC.Tc.Solver.simpl_top to simplifyTopWanteds
* A bit of refactoring in bindExplicitTKTele, to avoid the
footwork with Either. Simpler now.
* Move promoteTyVar from GHC.Tc.Solver to GHC.Tc.Utils.TcMType

PmCheck: Long-distance information for LocalBinds (#18626)
Now `desugarLocalBind` (formerly `desugarLet`) reasons about
* `FunBind`s that
* Have no pattern matches (so which aren't functions)
* Have a singleton match group with a single GRHS
* (which may have guards)
* and looks through trivial post-typechecking `AbsBinds` in doing so
to pick up the introduced renamings.
And desugars to `PmLet` LYG-style guards. Since GRHSs are no longer
denoted simply by `NonEmpty PmGRHS`, but also need to carry a `[PmGrd]`
for the `PmLet`s from `LocalBind`s, I added `PmGRHSs` to capture that.
Since we call out to the desugarer more often, I found that there were
superfluous warnings emitted when desugaring e.g. case expressions.
Thus, I made sure that we deactivate any warnings in the LYG desugaring
steps by the new wrapper function `noCheckDs`.
There's a regression test in `T18626`. Fixes #18626.

Use ADTs for parser errors/warnings
Haskell and Cmm parsers/lexers now report errors and warnings using ADTs
defined in GHC.Parser.Errors. They can be printed using functions in
GHC.Parser.Errors.Ppr.
Some of the errors provide hints with a separate ADT (e.g. to suggest to
turn on some extension). For now, however, hints are not consistent
across all messages. For example some errors contain the hints in the
main message. I didn't want to change any message with this patch. I
expect these changes to be discussed and implemented later.
Surprisingly, this patch enhances performance. On CI

Don't attach CPR signatures to NOINLINE data structures (#18154)
Because the generated `KindRep`s don't have an unfolding, !3230 did not
actually stop to compute, attach and serialise unnecessary CPR
signatures for them. As already said in
`Note [CPR for data structures]`, that leads to bloated interface
files which is ultimately quadratic for Nested CPR.
So we don't attach any CPR signature to bindings that
* Are not thunks (because thunks are not in WHNF)
* Have arity 0 (which means the top-level constructor is not a lambda)
If the data structure has an unfolding, we continue to look through it.
If not (as is the case for `KindRep`s), we look at the unchanged CPR
signature and see `topCprType`, as expected.

Inline `integerDecodeDouble#` and constant-fold `decodeDouble_Int64#` instead
Currently, `integerDecodeDouble#` is known-key so that it can be
recognised in constant folding. But that is very brittle and doesn't
survive worker/wrapper, which we even do for
`NOINLINE` things since #13143.
Also it is a trade-off: The implementation of `integerDecodeDouble#`
allocates an `Integer` box that never cancels aways if we don't inline
it.
Hence we recognise the `decodeDouble_Int64#` primop instead in constant
folding, so that we can inline `integerDecodeDouble#`. As a result,
`integerDecodeDouble#` no longer needs to be known-key.
While doing so, I realised that we don't constant-fold
`decodeFloat_Int#` either, so I also added a RULE for it.
`integerDecodeDouble` is dead, so I deleted it.
Part of #18092. This improves the 32-bit `realToFrac`/`toRational`:

Previously `TICK_BUMP_BY` was defined as
```c

Yet the tickers themselves were defined as `StgInt`s. This happened to
work out correctly on Linux, where `CLong` is 64-bits. However, it
failed on Windows, where `CLong` is 32-bits, resulting in #18782.

rts: fix race condition in StgCRun
On windows the stack has to be allocated 4k at a time, otherwise we get
a segfault. This is done by using a helper ___chkstk_ms that is provided
by libgcc. The Haskell side already knows how to handle this but we need
to do the same from STG. Previously we would drop the stack in StgRun
but would only make it valid whenever the scheduler loop ran.
This approach was fundamentally broken in that it falls apart when you
take a signal from the OS. We see it less often because you initially
get allocated a 1MB stack block which you have to blow past first.
Concretely this means we must always keep the stack valid.
Fixes #18601.

Fall back to types when looking up data constructors (#18740)
Before this patch, referring to a data constructor in a term-level
context led to a scoping error:

After this patch, the renamer falls back to the type namespace
and successfully finds the Int. It is then rejected in the type
checker with a more useful error message:
<interactive>:1:4: error:
• Illegal term-level use of the type constructor ‘Int’
imported from ‘Prelude’ (and originally defined in ‘GHC.Types’)
• In the first argument of ‘id’, namely ‘Int’
In the expression: id Int

Unification of Nat and Naturals
This commit removes the separate kind 'Nat' and enables promotion
of type 'Natural' for using as type literal.
It partially solves #10776
Now the following code will be successfully typechecked:
data C = MkC Natural
type CC = MkC 1
Before this change we had to create the separate type for promotion
data C = MkC Natural
data CP = MkCP Nat
type CC = MkCP 1
But CP is uninhabited in terms.
For backward compatibility type synonym `Nat` has been made:
type Nat = Natural

Make DataKinds the sole arbiter of kind-level literals (and friends)
Previously, the use of kind-level literals, promoted tuples,
and promoted lists required enabling both `DataKinds` and
`PolyKinds`. This made sense back in a `TypeInType` world, but not so
much now that `TypeInType`'s role has been superseded. Nowadays,
`PolyKinds` only controls kind polymorphism, so let's make `DataKinds`
the thing that controls the other aspects of `TypeInType`, which include
literals, promoted tuples and promoted lists.
There are some other things that overzealously required `PolyKinds`,
which this patch fixes as well:
* Previously, using constraints in kinds (e.g., `data T :: () -> Type`)
required `PolyKinds`, despite the fact that this is orthogonal to kind
polymorphism. This now requires `DataKinds` instead.
* Previously, using kind annotations in kinds
(e.g., `data T :: (Type :: Type) -> Type`) required both `KindSignatures`
and `PolyKinds`. This doesn't make much sense, so it only requires
`KindSignatures` now.
Fixes #18831.

Fix some missed opportunities for preInlineUnconditionally
There are two signficant changes here:
* Ticket #18815 showed that we were missing some opportunities for
preInlineUnconditionally. The one-line fix is in the code for
GHC.Core.Opt.Simplify.Utils.preInlineUnconditionally, which now
switches off only for INLINE pragmas. I expanded
Note [Stable unfoldings and preInlineUnconditionally] to explain.
* When doing this I discovered a way in which preInlineUnconditionally
was occasionally /too/ eager. It's all explained in
Note [Occurrences in stable unfoldings] in GHC.Core.Opt.OccurAnal,
and the one-line change adding markAllMany to occAnalUnfolding.
I also got confused about what NoUserInline meant, so I've renamed
it to NoUserInlinePrag, and changed its pretty-printing slightly.
That led to soem error messate wibbling, and touches quite a few
files, but there is no change in functionality.
I did a nofib run. As expected, no significant changes.

I'm allowing a max-residency increase for T10370, which seems
very irreproducible. (See comments on !4241.) There is always
sampling error for max-residency measurements; and in any case
the change shows up on some platforms but not others.

Remove Proxy# argument in Data.Typeable.Internal
No longer neccessary - TypeRep is now indexed, there is no ambiguity.
Also fix a comment in Evidence.hs, IsLabel no longer takes a Proxy#.

WIP: Check for large tuples more thoroughly in the typechecker
This unifies the treatment of how GHC checks for constraint tuples
and other tuples by:
* Migrating the `checkTupSize` renamer check to the typechecker,
* Moving the existing `bigConstraintTuple` typechecker validity
check to `checkCTupSize` for consistency with `checkTupSize`, and
* Consistently using `check(C)TupSize` when typechecking tuple
names, expressions, patterns, and types.
* Removing the unused `HsConstraintTuple` constructor of
`HsTupleSort`.
Fixes #18723.
