Description Michael Saboff 2017-06-13 12:49:15 PDT
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.
