            Bug ID: 173322
           Summary: Refactor AbsenceOfSetter to something like
                    AbsenceOfSetEffects
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: msaboff at apple.com

The fix to <https://bugs.webkit.org/show_bug.cgi?id=173321> - "DFG doesn't properly handle a property that is change to read only in a prototype" is to add a check for ReadOnly to the AbsenceOfSetter in PropertyCondition::isStillValidAssumingImpurePropertyWatchpoint().  Talking to Phil Pizlo it makes sense to reflect the changed functionality in the name of AbsenceOfSetter in all of it's uses.
