      Fix grouping for pattern synonyms · 29928f29
      Simon Peyton Jones authored
      When grouping pattern synonyms in the desugarer, to find when a single
      match will work for the whole group, we use `Match.sameGroup`.  But this
      function was declaring two pattern-synonym matches equal to often.
      Result: Lint errors and broken semantics.
      
      The fix is easy.  See Note [Pattern synonym groups].
      
      Re-do typechecking for pattern synonym signatures

      Rework Template Haskell's handling of strictness · f975b0b1
      Ryan Scott authored
      Currently, Template Haskell's treatment of strictness is not enough to
      cover all possible combinations of unpackedness and strictness. In
      addition, it isn't equipped to deal with new features (such as
      `-XStrictData`) which can change a datatype's fields' strictness during
      compilation.
      
      To address this, I replaced TH's `Strict` datatype with
      `SourceUnpackedness` and `SourceStrictness` (which give the programmer a
      more complete toolkit to configure a datatype field's strictness than
      just `IsStrict`, `IsLazy`, and `Unpack`). I also added the ability to
      reify a constructor fields' strictness post-compilation through the
      `reifyConStrictness` function.
      
      Fixes #10697.

      Retain AnnTilde in splitTildeApps · b407bd77
      Alan Zimmerman authored
      splitTildeApps can introduce a new HsAppInfix for a tilde, with a fresh
      SrcSpan, disconnecting its existing AnnTilde API Annotation.
      
      A tilde needs AnnTilde to render properly, this patch adds a new one on
      the fresh SrcSpan

      Make HsAppsType contents Located · ff923954
      Alan Zimmerman authored
      An HsAppInfix can carry a qconop/varop preceded by a SIMPLEQUOTE as a
      Located RdrName.
      
      In this case AnnSimpleQuote is attached to the Located HsAppType.
      
          | SIMPLEQUOTE qconop            {% ams (sLL $1 $> $ HsAppInfix $2)
                                                 [mj AnnSimpleQuote $1] }
          | SIMPLEQUOTE varop             {% ams (sLL $1 $> $ HsAppInfix $2)
                                                 [mj AnnSimpleQuote $1] }
      
      This patch changes
      
          data HsType name
            ...
            | HsAppsTy [HsAppType name]
      
      to
      
          data HsType name
            ...
            | HsAppsTy [LHsAppType name]
      
      so that the annotation is not discarded when it reaches the ParsedSource

      Fix GHCi segfault in Windows 32bit · aa7fb9a6
      Tamar Christina authored
      Summary:
      Add missing calling convention to function pointer,
      incorrect `cdecl` calling convention which should be `stdcall`
      on x86 was causing the stack to be corrupted. When it tried to
      return from the function the return pointer would be invalid.
