            Bug ID: 275113
           Summary: AX: isolated tree nodes should store frequent bool
                    attributes in a bitfield
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2

          Assignee: webkit-unassigned at lists.webkit.org

A lot of memory is wasted in AX isolated tree nodes storing boolean attributes in an expensive HashMap. By storing some of the most common ones in a bitfield we can save memory. The most rare ones are still a good fit for the HashMap.
