The upper boundary can be estimated since 999... = 10^k - 1 has to
be equal to 9^5 + 9^5 + ... = k 9^5, which yields the maximum
condition k 9^5 = 10^k - 1. A numeric solution for this is 5.51257,
which yields a maximum of 10^5.51257 = 325514.24.

\subsection{Wired in Ids}
* *
************************************************************************
Note [Wired-in Ids]
~~~~~~~~~~~~~~~~~~~
There are several reasons why an Id might appear in the wiredInIds:
(1) The ghcPrimIds are wired in because they can't be defined in
Haskell at all, although the can be defined in Core. They have
compulsory unfoldings, so they are always inlined and they have
no definition site. Their home module is GHC.Prim, so they
also have a description in primops.txt.pp, where they are called
'pseudoops'.
(2) The 'error' function, eRROR_ID, is wired in because we don't yet have
a way to express in an interface file that the result type variable
is 'open'; that is can be unified with an unboxed type
[The interface file format now carry such information, but there's
no way yet of expressing at the definition site for these
error-reporting functions that they have an 'open'
result type. -- sof 1/99]
(3) Other error functions (rUNTIME_ERROR_ID) are wired in (a) because
the desugarer generates code that mentions them directly, and
(b) for the same reason as eRROR_ID
(4) lazyId is wired in because the wired-in version overrides the
strictness of the version defined in GHC.Base
In cases (2-4), the function has a definition in a library module, and
can be called; but the wired-in version means that the details are
never read from that module's interface file; instead, the full definition
is right here.

************************************************************************

\subsection{Data constructors}
* *
************************************************************************
The wrapper for a constructor is an ordinary top-level binding that evaluates
any strict args, unboxes any args that are going to be flattened, and calls
the worker.
We're going to build a constructor that looks like:
data (Data a, C b) => T a b = T1 !a !Int b
T1 = /\ a b ->
\d1::Data a, d2::C b ->
\p q r -> case p of { p ->
case q of { q ->
Con T1 [a,b] [p,q,r]}}
Notice that
* d2 is thrown away --- a context in a data decl is used to make sure
one *could* construct dictionaries at the site the constructor
is used, but the dictionary isn't actually used.
* We have to check that we can construct Data dictionaries for
the types a and Int. Once we've done that we can throw d1 away too.
* We use (case p of q -> ...) to evaluate p, rather than "seq" because
all that matters is that the arguments are evaluated. "seq" is
very careful to preserve evaluation order, which we don't need
to be here.
You might think that we could simply give constructors some strictness
info, like PrimOps, and let CoreToStg do the let-to-case transformation.
But we don't do that because in the case of primops and functions strictness
is a *property* not a *requirement*. In the case of constructors we need to
do something active to evaluate the argument.
Making an explicit case expression allows the simplifier to eliminate
it in the (common) case where the constructor arg is already evaluated.
Note [Wrappers for data instance tycons]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In the case of data instances, the wrapper also applies the coercion turning
the representation type into the family instance type to cast the result of
the wrapper. For example, consider the declarations
data family Map k :: * -> *
data instance Map (a, b) v = MapPair (Map a (Pair b v))
The tycon to which the datacon MapPair belongs gets a unique internal
name of the form :R123Map, and we call it the representation tycon.
In contrast, Map is the family tycon (accessible via
tyConFamInst_maybe). A coercion allows you to move between
representation and family type. It is accessible from :R123Map via
tyConFamilyCoercion_maybe and has kind
Co123Map a b v :: {Map (a, b) v ~ :R123Map a b v}
The wrapper and worker of MapPair get the types
-- Wrapper
$WMapPair :: forall a b v. Map a (Map a b v) -> Map (a, b) v
$WMapPair a b v = MapPair a b v `cast` sym (Co123Map a b v)
-- Worker
MapPair :: forall a b v. Map a (Map a b v) -> :R123Map a b v
This coercion is conditionally applied by wrapFamInstBody.
It's a bit more complicated if the data instance is a GADT as well!
data instance T [a] where
T1 :: forall b. b -> T [Maybe b]
Hence we translate to
-- Wrapper
$WT1 :: forall b. b -> T [Maybe b]
$WT1 b v = T1 (Maybe b) b (Maybe b) v
`cast` sym (Co7T (Maybe b))
-- Worker
T1 :: forall c b. (c ~ Maybe b) => b -> :R7T c
-- Coercion from family type to representation type
Co7T a :: T [a] ~ :R7T a
Note [Newtype datacons]
~~~~~~~~~~~~~~~~~~~~~~~
The "data constructor" for a newtype should always be vanilla. At one
point this wasn't true, because the newtype arising from
class C a => D a
looked like
newtype T:D a = D:D (C a)
so the data constructor for T:C had a single argument, namely the
predicate (C a). But now we treat that as an ordinary argument, not
part of the theta-type, so all is well.
************************************************************************

\subsection{Dictionary selectors}
* *
************************************************************************
Selecting a field for a dictionary. If there is just one field, then
there's nothing to do.
Dictionary selectors may get nested forall-types. Thus:
class Foo a where
op :: forall b. Ord b => a -> b -> b
Then the top-level type for op is
op :: forall a. Foo a =>
forall b. Ord b =>
a -> b -> b

We pass Maybe [HsImplBang] to mkDataConRep to make use of HsImplBangs
from imported modules.
- Nothing <=> use HsSrcBangs
- Just bangs <=> use HsImplBangs
For imported types we can't work it all out from the HsSrcBangs,
because we want to be very sure to follow what the original module
(where the data type was declared) decided, and that depends on what
flags were enabled when it was compiled. So we record the decisions in
the interface file.
The HsImplBangs passed are in 1-1 correspondence with the
dataConOrigArgTys of the DataCon.

Note [Unpack one-wide fields]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The flag UnboxSmallStrictFields ensures that any field that can
(safely) be unboxed to a word-sized unboxed field, should be so unboxed.
For example:
data A = A Int#
newtype B = B A
data C = C !B
data D = D !C
data E = E !()
data F = F !D
data G = G !F !F
All of these should have an Int# as their representation, except
G which should have two Int#s.
However
data T = T !(S Int)
data S = S !a
Here we can represent T with an Int#.
Note [Recursive unboxing]
~~~~~~~~~~~~~~~~~~~~~~~~~
Consider
data R = MkR {-# UNPACK #-} !S Int
data S = MkS {-# UNPACK #-} !Int
The representation arguments of MkR are the *representation* arguments
of S (plus Int); the rep args of MkS are Int#. This is all fine.
But be careful not to try to unbox this!
data T = MkT {-# UNPACK #-} !T Int
Because then we'd get an infinite number of arguments.
Here is a more complicated case:
data S = MkS {-# UNPACK #-} !T Int
data T = MkT {-# UNPACK #-} !S Int
Each of S and T must decide independently whether to unpack
and they had better not both say yes. So they must both say no.
Also behave conservatively when there is no UNPACK pragma
data T = MkS !T Int
with -funbox-strict-fields or -funbox-small-strict-fields
we need to behave as if there was an UNPACK pragma there.
But it's the *argument* type that matters. This is fine:
data S = MkS S !Int
because Int is non-recursive.

These Ids can't be defined in Haskell. They could be defined in

ensure that they were definitely, definitely inlined, because there is
no curried identifier for them. That's what mkCompulsoryUnfolding
does. If we had a way to get a compulsory unfolding from an interface
file, we could do that, but we don't right now.
unsafeCoerce# isn't so much a PrimOp as a phantom identifier, that
just gets expanded into a type coercion wherever it occurs. Hence we
add it as a built-in Id with an unfolding here.
The type variables we use here are "open" type variables: this means
they can unify with both unlifted and lifted types. Hence we provide
another gun with which to shoot yourself in the foot.

Note [dollarId magic]
~~~~~~~~~~~~~~~~~~~~~
The only reason that ($) is wired in is so that its type can be
forall (a:*, b:Open). (a->b) -> a -> b
That is, the return type can be unboxed. E.g. this is OK
foo $ True where foo :: Bool -> Int#
because ($) doesn't inspect or move the result of the call to foo.
See Trac #8739.
There is a special typing rule for ($) in TcExpr, so the type of ($)
isn't looked at there, BUT Lint subsequently (and rightly) complains
if sees ($) applied to Int# (say), unless we give it a wired-in type
as we do here.
Note [Unsafe coerce magic]
~~~~~~~~~~~~~~~~~~~~~~~~~~
We define a *primitive*
GHC.Prim.unsafeCoerce#
and then in the base library we define the ordinary function
Unsafe.Coerce.unsafeCoerce :: forall (a:*) (b:*). a -> b
unsafeCoerce x = unsafeCoerce# x
Notice that unsafeCoerce has a civilized (albeit still dangerous)
polymorphic type, whose type args have kind *. So you can't use it on
unboxed values (unsafeCoerce 3#).
In contrast unsafeCoerce# is even more dangerous because you *can* use
it on unboxed things, (unsafeCoerce# 3#) :: Int. Its type is
forall (a:OpenKind) (b:OpenKind). a -> b
Note [seqId magic]
~~~~~~~~~~~~~~~~~~
'GHC.Prim.seq' is special in several ways.
a) In source Haskell its second arg can have an unboxed type
x `seq` (v +# w)
But see Note [Typing rule for seq] in TcExpr, which
explains why we give seq itself an ordinary type
seq :: forall a b. a -> b -> b
and treat it as a language construct from a typing point of view.
b) Its fixity is set in LoadIface.ghcPrimIface
c) It has quite a bit of desugaring magic.
See DsUtils.hs Note [Desugaring seq (1)] and (2) and (3)
d) There is some special rule handing: Note [User-defined RULES for seq]
Note [User-defined RULES for seq]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Roman found situations where he had
case (f n) of _ -> e
where he knew that f (which was strict in n) would terminate if n did.
Notice that the result of (f n) is discarded. So it makes sense to
transform to
case n of _ -> e
Rather than attempt some general analysis to support this, I've added
enough support that you can do this using a rewrite rule:
RULE "f/seq" forall n. seq (f n) = seq n
You write that rule. When GHC sees a case expression that discards
its result, it mentally transforms it to a call to 'seq' and looks for
a RULE. (This is done in Simplify.rebuildCase.) As usual, the
correctness of the rule is up to you.
VERY IMPORTANT: to make this work, we give the RULE an arity of 1, not 2.
If we wrote
RULE "f/seq" forall n e. seq (f n) e = seq n e
with rule arity 2, then two bad things would happen:
- The magical desugaring done in Note [seqId magic] item (c)
for saturated application of 'seq' would turn the LHS into
a case expression!
- The code in Simplify.rebuildCase would need to actually supply
the value argument, which turns out to be awkward.
Note [Built-in RULES for seq]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We also have the following built-in rule for seq
seq (x `cast` co) y = seq x y
This eliminates unnecessary casts and also allows other seq rules to
match more often. Notably,
seq (f x `cast` co) y --> seq (f x) y
and now a user-defined rule for seq (see Note [User-defined RULES for seq])
may fire.
Note [lazyId magic]
~~~~~~~~~~~~~~~~~~~
lazy :: forall a?. a? -> a? (i.e. works for unboxed types too)
'lazy' is used to make sure that a sub-expression, and its free variables,
are truly used call-by-need, with no code motion. Key examples:
* pseq: pseq a b = a `seq` lazy b
We want to make sure that the free vars of 'b' are not evaluated
before 'a', even though the expression is plainly strict in 'b'.
* catch: catch a b = catch# (lazy a) b
Again, it's clear that 'a' will be evaluated strictly (and indeed
applied to a state token) but we want to make sure that any exceptions
arising from the evaluation of 'a' are caught by the catch (see
Trac #11555).
Implementing 'lazy' is a bit tricky:
* It must not have a strictness signature: by being a built-in Id,
all the info about lazyId comes from here, not from GHC.Base.hi.
This is important, because the strictness analyser will spot it as
strict!
* It must not have an unfolding: it gets "inlined" by a HACK in
CorePrep. It's very important to do this inlining *after* unfoldings
are exposed in the interface file. Otherwise, the unfolding for
(say) pseq in the interface file will not mention 'lazy', so if we
inline 'pseq' we'll totally miss the very thing that 'lazy' was
there for in the first place. See Trac #3259 for a real world
example.
* Suppose CorePrep sees (catch# (lazy e) b). At all costs we must
avoid using call by value here:
case e of r -> catch# r b
Avoiding that is the whole point of 'lazy'. So in CorePrep (which
generate the 'case' expression for a call-by-value call) we must
spot the 'lazy' on the arg (in CorePrep.cpeApp), and build a 'let'
instead.
* lazyId is defined in GHC.Base, so we don't *have* to inline it. If it
appears un-applied, we'll end up just calling it.
Note [runRW magic]
~~~~~~~~~~~~~~~~~~
Some definitions, for instance @runST@, must have careful control over float out
of the bindings in their body. Consider this use of @runST@,
f x = runST ( \ s -> let (a, s') = newArray# 100 [] s
(_, s'') = fill_in_array_or_something a x s'
in freezeArray# a s'' )
If we inline @runST@, we'll get:
f x = let (a, s') = newArray# 100 [] realWorld#{-NB-}
(_, s'') = fill_in_array_or_something a x s'
in freezeArray# a s''
And now if we allow the @newArray#@ binding to float out to become a CAF,
we end up with a result that is totally and utterly wrong:
f = let (a, s') = newArray# 100 [] realWorld#{-NB-} -- YIKES!!!
in \ x ->
let (_, s'') = fill_in_array_or_something a x s'
in freezeArray# a s''
All calls to @f@ will share a {\em single} array! Clearly this is nonsense and
must be prevented.
This is what @runRW#@ gives us: by being inlined extremely late in the
optimization (right before lowering to STG, in CorePrep), we can ensure that
no further floating will occur. This allows us to safely inline things like
@runST@, which are otherwise needlessly expensive (see #10678 and #5916).
While the definition of @GHC.Magic.runRW#@, we override its type in @MkId@
to be open-kinded,
runRW# :: forall (r1 :: RuntimeRep). (o :: TYPE r)
=> (State# RealWorld -> (# State# RealWorld, o #))
-> (# State# RealWorld, o #)
Note [The oneShot function]
~~~~~~~~~~~~~~~~~~~~~~~~~~~
In the context of making left-folds fuse somewhat okish (see ticket #7994
and Note [Left folds via right fold]) it was determined that it would be useful
if library authors could explicitly tell the compiler that a certain lambda is
called at most once. The oneShot function allows that.
'oneShot' is open kinded, i.e. the type variables can refer to unlifted
types as well (Trac #10744); e.g.
oneShot (\x:Int# -> x +# 1#)
Like most magic functions it has a compulsary unfolding, so there is no need
for a real definition somewhere. We have one in GHC.Magic for the convenience
of putting the documentation there.
It uses `setOneShotLambda` on the lambda's binder. That is the whole magic:
A typical call looks like
oneShot (\y. e)
after unfolding the definition `oneShot = \f \x[oneshot]. f x` we get
(\f \x[oneshot]. f x) (\y. e)
--> \x[oneshot]. ((\y.e) x)
--> \x[oneshot] e[x/y]
which is what we want.
It is only effective if the one-shot info survives as long as possible; in
particular it must make it into the interface in unfoldings. See Note [Preserve
OneShotInfo] in CoreTidy.
Also see https://ghc.haskell.org/trac/ghc/wiki/OneShot.
Note [magicDictId magic]
~~~~~~~~~~~~~~~~~~~~~~~~~
The identifier `magicDict` is just a place-holder, which is used to
implement a primitve that we cannot define in Haskell but we can write
in Core. It is declared with a place-holder type:
magicDict :: forall a. a
The intention is that the identifier will be used in a very specific way,
to create dictionaries for classes with a single method. Consider a class
like this:
class C a where
f :: T a
We are going to use `magicDict`, in conjunction with a built-in Prelude
rule, to cast values of type `T a` into dictionaries for `C a`. To do
this, we define a function like this in the library:
data WrapC a b = WrapC (C a => Proxy a -> b)
withT :: (C a => Proxy a -> b)
-> T a -> Proxy a -> b
withT f x y = magicDict (WrapC f) x y
The purpose of `WrapC` is to avoid having `f` instantiated.
Also, it avoids impredicativity, because `magicDict`'s type
cannot be instantiated with a forall. The field of `WrapC` contains
a `Proxy` parameter which is used to link the type of the constraint,
`C a`, with the type of the `Wrap` value being made.
Next, we add a built-in Prelude rule (see prelude/PrelRules.hs),
which will replace the RHS of this definition with the appropriate
definition in Core. The rewrite rule works as follows:
magicDict @t (wrap @a @b f) x y
---->
f (x `cast` co a) y
The `co` coercion is the newtype-coercion extracted from the type-class.
The type class is obtain by looking at the type of wrap.
-------------------------------------------------------------
@realWorld#@ used to be a magic literal, \tr{void#}. If things get
nasty as-is, change it back to a literal (@Literal@).
voidArgId is a Local Id used simply as an argument in functions
where we just want an arg to avoid having a thunk of unlifted type.
E.g.
x = \ void :: Void# -> (# p, q #)
This comes up in strictness analysis
Note [evaldUnfoldings]
~~~~~~~~~~~~~~~~~~~~~~
The evaldUnfolding makes it look that some primitive value is
evaluated, which in turn makes Simplify.interestingArg return True,
which in turn makes INLINE things applied to said value likely to be
inlined.

-- -- | Lam' t (Scope (Name a ()) (Expr t) a)
-- however it gets in the way of automatically deriving Functor, Foldable, and Traversable below
-- this I came up w/ instead - worked for a while
-- (but wasn't too sure, if it makes sense in the first place):
-- -- | Lam' t (Scope (Name t ()) (Expr t) a)
-- however, as then discovered, this gets in the way of making Expr bitraversable below,
-- which is not only nice to have (eg. for Text2String)
-- but essential for our position/range calculations
-- so we resort to using a fixed data type: String (or T.Text or whatever)
| Lam' t (Scope (Name String ()) (Expr t) a)

| Lams' [t] (Scope (Name String Int) (Expr t) a)
-- the caveat is that, that desugaring (so far generic: for any kind of Expr),
-- becomes tied to String (or...) that way, ie. if we want to desugar Lams' to Lam' etc.
-- (or we would need different versions of desugaring functions, for String, T.Text etc)
-- so Scopes w/ Names are really not that useful (and not really needed anyway),
-- they are just convenient to have when starting out w/ Bound.

-- Lams are desugared to Lam

-- | Parallel Arrays.
---
-- Parallel arrays use a fixed generic representation. All data stored in
-- them is converted to the generic representation, and we have a small
-- number of operators that work on arrays of these generic types.
--
-- Representation types include Ints, Floats, Tuples and Sums, so arrays of
-- these types can be stored directly. However, user defined algebraic data
-- needs to be converted as we don't have operators that work directly on
-- arrays of these types.
--
-- The top-level PArray type is built up from several type families and
-- clases:
--
-- PArray - This is the top level type. It holds an array length,
-- and array data in the generic representation (PData).
--
-- PRepr - Family of types that can be converted to the generic
-- representation. We supply instances for basic types
-- like Ints Floats etc, but the vectoriser needs to make
-- the instances for user-defined data types itself.
-- PA class - Contains methods to convert to and from the generic
-- representation (PData).
--
-- PData - Family of types that can be stored directly in parallel
-- arrays. We supply all the PData instances we need here
-- in the library.
-- PR class - Contains methods that work directly on parallel arrays.
-- Most of these are just wrappers for the corresponding
-- U.Array operators.
--
-- Scalar class - Contains methods to convert between the generic
-- representation (PData) and plain U.Arrays.
--
-- Note that the PRepr family and PA class are related.
-- so are the PData family and PR class.

-- NOTE:
-- Most of these functions just export the corresponding "vectorised"
-- function from "Data.Array.Parallel.Lifted.Closure". We don't export
-- higher-order functions like map and filter because the versions
-- from there want closures as their function parameters.
--
-- Instead, we should probably move the first-order "vectorised"
-- functions from D.A.P.L.Closure into this module, and just define
-- the higher-order and lifted ones there.
--
-- We still want to export these plain PArray functions to make it easier
-- to convert between vectorised and unvectorised code in benchmarks.
