      Fix compiling int and guard patterns · 4cadd369
      Yorick Peterse authored
      Integer patterns could break certain nested patterns, such as
      `(4, (5, 7)) -> A` due to how fallback rows were handled: they were only
      processed in the fallback case of the outer pattern, resulting in the
      inner pattern not having enough/the expected rows to process. This in
      turn could result in exhaustive matches being treated as non-exhaustive.
      For example, prior to this commit a match like this was considered
      non-exhaustive:
      
          match (10, 20) {
            case (10, 20) -> A
            case (_, _)   -> B
          }
      
      As part of this commit we also fix guard patterns, which were broken
      when the pattern was the same. For example, matches like this weren't
      handled correctly:
      
          match 42 {
            case 42 if x -> A
            case 42 if y -> B
            case 42      -> C
            ...
          }
      
      This was caused by the compiler keeping track of the integer columns
      already processed, without taking into account guard expressions. This
      would result in `case 42 if y` and `case 42` being skipped.

      Optimise compiling of guards · fa1963d0
      Yorick Peterse authored
      In the jacobs2021 implementation we don't need to duplicate all initial
      rows. Instead, when we reach a Success node we can compile the remaining
      rows into a guard fallback. For integer patterns this requires some
      extra work, but for regular constructor patterns no changes are
      necessary.
      
      Thanks to Jules Jacobs for suggesting this approach via Email.
