Heap-box doubles in QML engine

    XMLWordPrintable

Details

    Description

      This will require

      1. a different tagging scheme for QV4::Value
      2. Creating the managed types for doubles
      3. Adjusting QJSValue to
        • allocate doubles on the (native) heap (no engine available in the ctor taking a double) and
        • to handle both boxed doubles and heap allocated doubles (compare the current string handling)
      4. Evaluating the performance and memory impact of the initial implementation
