Module      : GHC.Hs.Utils
Description : Generic helpers for the HsSyn type.
Copyright   : (c) The University of Glasgow, 1992-2023

Here we collect a variety of helper functions that construct or
analyse HsSyn.  All these functions deal with generic HsSyn; functions
which deal with the instantiated versions are located elsewhere:

   Parameterised by          Module
   ----------------          -------------
   GhcPs/RdrName             GHC.Parser.PostProcess
   GhcRn/Name                GHC.Rename.*
   GhcTc/Id                  GHC.Tc.Zonk.Type

The @mk*@ functions attempt to construct a not-completely-useless SrcSpan
from their components, compared with the @nl*@ functions which
just attach noSrcSpan to everything.

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

Get all the binders in some HsBindGroups, IN THE ORDER OF APPEARANCE. eg.

...
where
  (x, y) = ...
  f i j  = ...
  [a, b] = ...

it should return [x, y, f, a, b] (remember, order important).

Note [Collect binders only after renaming]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
These functions should only be used on HsSyn *after* the renamer,
to return a [Name] or [Id].  Before renaming the record punning
and wild-card mechanism makes it hard to know what is bound.
So these functions should not be applied to (HsSyn RdrName)

Note [isUnliftedHsBind]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The function isUnliftedHsBind tells if the binding binds a variable of
unlifted type.  e.g.

  - I# x = blah
  - Just (I# x) = blah

isUnliftedHsBind is used in two ways:

* To complain if we make a top-level binding for a variable of unlifted
  type. E.g. any of the above bindings are illegal at top level

* To generate a case expression for a non-recursive local let.  E.g.
     let Just (I# x) = blah in body
  ==>
     case blah of Just (I# x) -> body
  See GHC.HsToCore.Expr.dsUnliftedBind.

Wrinkles:

(W1) For AbsBinds we must check if the local letrec generated by desugaring
     AbsBinds would be unlifted; so we just recurse into the abs_binds. E.g.
       f :: Num a => (# a, a #)
       g :: Num a => a -> a
       f = ...g...
       g = ...g...

    The top-level bindings for f,g are not unlifted (because of the Num a =>),
    but the local, recursive, monomorphic bindings are:
      t = /\a \(d:Num a).
         letrec fm :: (# a, a #) = ...g...
                gm :: a -> a = ...f...
         in (fm, gm)

   Here the binding for 'fm' is illegal.  So we recurse into the abs_binds

(W2) BUT we have a special case when abs_sig is true;
     see Note [The abs_sig field of AbsBinds] in GHC.Hs.Binds

(W3) isUnliftedHsBind returns False even if the binding itself is
     unlifted, provided it binds only lifted variables. E.g.
      -  (# a,b #) = (# reverse xs, xs #)

      -  x = sqrt# y#  :: Float#

      -  type Unl :: UnliftedType
         data Unl = MkUnl Int
         MkUnl z = blah

     In each case the RHS of the "=" has unlifted type, but isUnliftedHsBind
     returns False.  Reason: see GHC Proposal #35
        https://github.com/ghc-proposals/ghc-proposals/blob/master/
        proposals/0035-unbanged-strict-patterns.rst

(W4) In particular, (W3) applies to a pattern that binds no variables at all.
     So   { _ = sqrt# y :: Float# } returns False from isUnliftedHsBind, but
          { x = sqrt# y :: Float# } returns True.
     This is arguably a bit confusing (see #22719)

Note [Dictionary binders in ConPatOut]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Should we collect dictionary binders in ConPatOut? It depends! Use CollectFlag
to choose.

1. Pre-typechecker there are no ConPatOuts. Use CollNoDictBinders flag.

2. In the desugarer, most of the time we don't want to collect evidence binders,
   so we also use CollNoDictBinders flag.

   Example of why it matters:

   In a lazy pattern, for example f ~(C x y) = ..., we want to generate bindings
   for x,y but not for dictionaries bound by C.
   (The type checker ensures they would not be used.)

   Here's the problem.  Consider

        data T a where
           C :: Num a => a -> Int -> T a

        f ~(C (n+1) m) = (n,m)

   Here, the pattern (C (n+1)) binds a hidden dictionary (d::Num a),
   and *also* uses that dictionary to match the (n+1) pattern.  Yet, the
   variables bound by the lazy pattern are n,m, *not* the dictionary d.
   So in mkSelectorBinds in GHC.HsToCore.Utils, we want just m,n as the
   variables bound.

   So in this case, we do *not* gather (a) dictionary and (b) dictionary
   bindings as binders of a ConPatOut pattern.


3. On the other hand, desugaring of arrows needs evidence bindings and uses
   CollWithDictBinders flag.

   Consider

        h :: (ArrowChoice a, Arrow a) => Int -> a (Int,Int) Int
        h x = proc (y,z) -> case compare x y of
                        GT -> returnA -< z+x

   The type checker turns the case into

        case compare x y of
          GT { $dNum_123 = $dNum_Int } -> returnA -< (+) $dNum_123 z x

   That is, it attaches the $dNum_123 binding to a ConPatOut in scope.

   During desugaring, evidence binders must be collected because their sets are
   intersected with free variable sets of subsequent commands to create
   (minimal) command environments.  Failing to do it properly leads to bugs
   (e.g., #18950).

   Note: attaching evidence binders to existing ConPatOut may be suboptimal for
   arrows.  In the example above we would prefer to generate:

        case compare x y of
          GT -> returnA -< let $dNum_123 = $dNum_Int in (+) $dNum_123 z x

   So that the evidence isn't passed into the command environment. This issue
   doesn't arise with desugaring of non-arrow code because the simplifier can
   freely float and inline let-expressions created for evidence binders. But
   with arrow desugaring, the simplifier would have to see through the command
   environment tuple which is more complicated.

{- Note [Collecting record fields in data declarations]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When renaming a data declaration that includes record constructors, we are, in
the end, going to to create a mapping from constructor to its field labels,
to store in 'GREInfo' (see 'IAmConLike'). This allows us to know, in the renamer,
which constructor has what fields.

In order to achieve this, we return the constructor and field information from
hsConDeclsBinders in the following format:

  - [(ConRdrName, [Located Int])], a list of the constructors, each associated
    with its record fields, in the form of a list of Int indices into...
  - IntMap FieldOcc, an IntMap of record fields.

(In actual fact, we use [(ConRdrName, Maybe [Located Int])], with Nothing indicating
that the constructor has unlabelled fields: see Note [Local constructor info in the renamer]
in GHC.Types.GREInfo.)

This allows us to do the following (see GHC.Rename.Names.getLocalNonValBinders.new_tc):

  - create 'Name's for each of the record fields, to get IntMap FieldLabel,
  - create 'Name's for each of the constructors, to get [(ConName, [Int])],
  - look up the FieldLabels of each constructor, to get [(ConName, [FieldLabel])].

NB: This can be a bit tricky to get right in the presence of data types with
duplicate constructors or fields. Storing locations allows us to report an error
for duplicate field declarations, see test cases T9156 T9156_DF.
Other relevant test cases: rnfail015.

Note [SrcSpan for binders]
~~~~~~~~~~~~~~~~~~~~~~~~~~
When extracting the (Located RdrName) for a binder, at least for the
main name (the TyCon of a type declaration etc), we want to give it
the @SrcSpan@ of the whole /declaration/, not just the name itself
(which is how it appears in the syntax tree).  This SrcSpan (for the
entire declaration) is used as the SrcSpan for the Name that is
finally produced, and hence for error messages.  (See #8607.)

Note [Binders in family instances]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In a type or data family instance declaration, the type
constructor is an *occurrence* not a binding site
    type instance T Int = Int -> Int   -- No binders
    data instance S Bool = S1 | S2     -- Binders are S1,S2


************************************************************************
*                                                                      *
        Collecting binders the user did not write
*                                                                      *
************************************************************************

The job of the following family of functions is to run through binding sites and find
the set of all Names that were defined "implicitly", without being explicitly written
by the user.

Note [Collecting implicit binders]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We collect all the RHS Names that are implicitly introduced by record wildcards,
so that we can:

  - avoid warning the user when they don't use those names (#4404),
  - report deprecation warnings for deprecated fields that are used (#23382).

The functions that collect implicit binders return a collection of 'ImplicitFieldBinders',
which associates each implicitly-introduced record field with the bound variables in the
RHS of the record field pattern, e.g. in

  data R = MkR { fld :: Int }
  foo (MkR { .. }) = fld

the renamer will elaborate this to

  foo (MkR { fld = fld_var }) = fld_var

and the implicit binders function will return

  [ ImplicitFieldBinders { implFlBndr_field = fld
                         , implFlBndr_binders = [fld_var] } ]

This information is then used:

  - in the calls to GHC.Rename.Utils.checkUnusedRecordWildcard, to emit
    a warning when a record wildcard binds no new variables (redundant record wildcard)
    or none of the bound variables are used (unused record wildcard).
  - in GHC.Rename.Utils.deprecateUsedRecordWildcard, to emit a warning
    when the field is deprecated and any of the binders are used.

NOTE: the implFlBndr_binders field should always be a singleton
      (since the RHS of an implicit binding should always be a VarPat,
      created in rnHsRecPatsAndThen.mkVarPat)
