      build system: Ensure there are no duplicate files in bindist list · fefcbfa8
      Ben Gamari authored
      Several executables inexplicably appear twice in bindist.list, which
      ends up producing multiple tar file entries, consequently breaking BSD
      tar during extraction. I spent a fair amount of time trying to work out
      where these duplicates were coming from to no avail. Since Hadrian is
      right around the corner I'm satisfied with a terrible hack: just uniq
      bindist.list before producing the bindist tarball.

      Fix #13983 by creating a TyConFlavour type, and using it · 6e3c901d
      Ryan Scott authored
      An error message was referring to a type synonym as a datatype.
      Annoyingly, learning that the TyCon over which the error message is
      operating is actually a type synonym was previously impossible, since
      that code only had access to a TcTyCon, which doesn't retain any
      information about what sort of TyCon it is.
      To rectify this, I created a new TyConFlavour datatype, intended to
      capture roughly what sort of TyCon we're dealing with. I then performing
      the necessary plumbing to ensure all TcTyCons have a TyConFlavour, and
      propagated this information through to the relevant error message.

      dmdAnal: Ensure that ExnStr flag isn't dropped inappropriately · c940e3b9
      Ben Gamari authored
      This fixes #13977 and consequently #13615. Here an optimization in the
      demand analyser was too liberal, causing us to drop the ExnStr flag and
      consequently resulting in incorrect demand signatures. This manifested
      as a segmentation fault in #13615 as we incorrectly concluded that an
      application of catchRetry# would bottom.
      Specifically, we had
          orElse' :: STM a -> STM a -> STM a
          orElse' x = catchRetry# x y
            where y = {- some action -}
      Where the catchRetry# primop places a demand of <xC(S),1*C1(U)> on its
      first argument. However, due to #13977 the demand analyser would assign
      a demand of <C(S),1*C1(U)> on the first argument of orElse'. Note the
      missing `x`.
          case orElse' bottomingAction anotherAction of { x -> Just x }
      being transformed to,
          case orElse' bottomingAction anotherAction of {}
      by the simplifier. This would naturally blow up when orElse' returned at
      runtime, causing the segmentation fault described in #13615.

      Allow visible type application for [] · c9e4c861
      Ryan Scott authored
      This amounts to a one-line change in `tcExpr`. I've added a Note to
      explain what is going on.
      This requires a separate change in the pattern-match checker to
      account for the fact that typechecked `[]` expressions become
      `ConLikeOut`s, not `ExplicitList`s.

      [skip ci] Temporarily disable split-sections on Windows. · f656fba1
      Tamar Christina authored
      This temporarily disabled split-sections again on Windows because
      of the overhead in linking it introduces. Unfortunately because BFD
      is so slow a testsuite run gets almost 2x slower. Simply linking
      Hello World takes an unacceptable long time.
      So for now, it'll be disabled as we look into different linkers such
      as LLD.
