      Pass -haddock to tests in should_compile_*flag*_nohaddock · c6007fe6
      thomie authored
      should_compile_flag_nohaddock and should_compile_noflag_nohaddock
      contain the exact same tests. By passing `-haddock` to the tests in
      should_compile_**flag**_nohaddock, at least they're now testing
      different things.
      
      Add documentation.

      Modifier letter in middle of identifier is ok · d738e664
      thomie authored
      Refactoring only. Cleanup some loose ends from #10196.
      
      Initially the idea was to only allow modifier letters at the end of
      identifiers. Since we later decided to allow modifier letters also in
      the middle of identifiers (because not doing so would not fix the
      regression completely), the names `suffix` and `okIdSuffixChar` don't
      seem appropriate anymore.
      
      Remove TODO. Move test from should_fail to should_compile.

      Delete support for deprecated "-- # ..."-style haddock options · 2f733b3a
      thomie authored
      A long time ago, you could use `"-- # <haddock options>"` to mean that
      `<haddock options.` should be passed to `haddock`. Since 2007
      (03d8585e), using `OPTIONS_HADDOCK` is
      the preferred way to do this.
      
      Why is ok to remove support for "-- # .."?
      
      * It is not mentioned in the Haddock user's guide, nor are there any
        tests that use it.
      
      * Ever since 2011 (b3e30449), it doesn't
        actually work anymore. The function `getOptionsFromFile` uses
        `gopt_unset dflags Opt_Haddock` for other reasons, so even when
        running ghc with `--haddock`, the following rule always fires when the
        lexer sees "-- # ..", and it gets treated as a normal comment:
      
      ```
          -- Next, match Haddock comments if no -haddock flag
          "-- " [$docsym \#] .* / { ifExtension (not . haddockEnabled) } { lineCommentToken }
      ```

      Unwire Typeable representation types · 206a8bf4
      Ben Gamari authored
      In order to make this work I needed to shuffle around typechecking a bit
      such that `TyCon` and friends are available during compilation of
      GHC.Types.  I also did a bit of refactoring of `TcTypeable`.

      Take type-function arity into account · a008eadf
      Simon Peyton Jones authored
      ...when computing the size of a call on the RHS of a type
      instance declaration.
      
      This came up in Trac #11581.  The change is in
         TcType.tcTyFamInsts
      which now trims the type arguments in a call.  See the
      comments with that function definition.

      Improve piResultTys and friends · 4d031cf9
      Simon Peyton Jones authored
      Several things here:
      
      * Re-implement piResultTys so that its substitution has
        the correct in-scope set
      
        That means paying close attention to performance, since as we
        discovered in Trac #11371, it's a heavily used function and
        is often used on ordinary function types, with no foralls to
        worry about substituting.
      
      * Kill off applyTys, which was just the same as piResultTys.
      
      * Re-engineer MkCore.mkCoreApps so that it calls piResultTys,
        rather than repeatedly calling piResultTy.

      (Another) minor refactoring of substitutions · b5292557
      Simon Peyton Jones authored
      No change in functionality here, but greater clarity:
      
      * In FamInstEnv.FlattenEnv, kill off the fi_in_scope field
        We are already maintaining an in-scope set in the fe_subst field,
        so it's silly do to it twice.
      
        (This isn't strictly connected to the rest of this patch, but
        the nomenclature changes below affect the same code, so I put
        them together.)
      
      * TyCoRep.extendTCVSubst used to take a TyVar or a CoVar and work
        out what to do, but in fact we almost always know which of the
        two we are doing.  So:
          - define extendTvSubst, extendCvSubst
          - and use them
      
      * Similar renamings in TyCoRep:
         - extendTCvSubstList        -->   extendTvSubstList
         - extendTCvSubstBinder      -->   extendTvSubstBinder
         - extendTCvSubstAndInScope  --> extendTvSubstAndInScope
      
      * Add Type.extendTvSubstWithClone, extendCvSubstWithClone
      
      * Similar nomenclature changes in Subst, SimplEnv, Specialise
      
      * Kill off TyCoRep.substTelescope (never used)

      Fix desugaring of bang-pattern let-bindings · 01449eb5
      Simon Peyton Jones authored
      When implementing Strict Haskell, the patch 46a03fbe didn't faithfully
      implement the semantics given in the manual. In particular there was
      an ad-hoc case in mkSelectorBinds for "strict and no binders" that
      didn't work.
      
      This patch fixes it, curing Trac #11572.
      
      Howver it forced me to think about banged let-bindings, and I rather
      think we do not have quite the right semantics yet, so I've opened
      Trac #11601.
