      Implement Unique supply with Addr# atomic primop · 6c771aaf
      Sylvain Henry authored
      Before this patch the compiler depended on the RTS way (threaded or not)
      to use atomic incrementation or not. This is wrong because the RTS is
      supposed to be switchable at link time, without recompilation.
      Now we always use atomic incrementation of the unique counter.

      Don't use absentError thunks for strict constructor fields · a8926e95
      Simon Peyton Jones authored
      This patch fixes #19133 by using LitRubbish for strict constructor
      fields, even if they are of lifted types.  Previously LitRubbish
      worked only for unlifted (but boxed) types.
      The change is very easy, although I needed a boolean field in
      LitRubbish to say whether or not it is lifted.  (That seemed easier
      than giving it another type argument.
      This is preparing for Andreas's work on establishing the invariant
      that strict constructor fields are always tagged and evaluated
      (see #16970).
      Meanwhile, nothing was actually wrong before, so there are no tests.

      Correct doctests · aa17b84d
      Oleg Grenrus authored
      It's simpler to assume that base is NoImplicitPrelude,
      otherwise running doctest on `GHC.*` modules would be tricky.
      OTOH, most `GHC.List` (where the most name clashes are) examples
      could be changed to use `import qualified Data.List as L`.
      (GHC.List examples won't show for Foldable methods...).
      With these changes majority of doctest examples are GHCi-"faithful",
      my WIP GHC-independent doctest runner reports nice summary:
      Examples: 582; Tried: 546; Skipped: 34; Success: 515; Errors: 33; Property Failures 2
      Most error cases are *Hangs forever*.
      I have yet to figure out how to demonstrate that in GHCi.
      Some of divergences are actually stack overflows, i.e. caught by
      Few errorful cases are examples of infinite output, e.g.
          >>> cycle [42]
      while correct, they confuse doctest.
      Another erroneous cases are where expected output has line comment, like
          >>> fmap show (Just 1)  --  (a   -> b)      -> f a       -> f b
          Just "1"                --  (Int -> String) -> Maybe Int -> Maybe String
      I think I just have to teach doctest to strip comments from expected
      This is a first patch in a series.
      There is plenty of stuff already.
