      Enable new warning for fragile/incorrect CPP #if usage · 7e340c2b
      Erik de Castro Lopo authored
      The C code in the RTS now gets built with `-Wundef` and the Haskell code
      (stages 1 and 2 only) with `-Wcpp-undef`. We now get warnings whereever
      `#if` is used on undefined identifiers.
      Test Plan: Validate on Linux and Windows

      Revert "Make raiseIO# produce topRes" · e83af07e
      David Feuer authored
      This reverts commit da4687f6.
      It's not entirely trivial to clean up the dead code this patch
      introduced. In particular, when we see
      case raiseIO# m s of
        s' -> e
      we want to know that `e` is dead. For scrutinees that are properly
      bottom (which we don't want to consider `raiseIO# m s` to be, this
      is handled by rewriting `bot` to `case bot of {}`. But if we do
      that for `raiseIO#`, we end up with
      case raiseIO# m s of {}
      which looks a lot like bottom and could confuse demand analysis.
      I think we need to wait with this change until we have a more
      complete story.

      Fix space leaks in simplifier (#13426) · e13419c5
      rwbarton authored
      The Join points commit (8d5cf8bf) introduced a space leak
      somewhere in the simplifier. The extra strictness added in this commit
      fixes the leak. Unfortunately I don't really understand the details.
      Unfortunately, the extra strictness appears to result in more overall
      allocations in some cases, even while the peak heap size decreases in others.
