+
+ [JSC] Introduce @putByIdDirectPrivate
+ https://bugs.webkit.org/show_bug.cgi?id=184400
+
+ Reviewed by Saam Barati.
+
+ This patch adds @putByIdDirectPrivate() to use it for builtin JS.
+ @getByIdDirectPrivate and @putByIdDirectPrivate are pair of intrinsics
+ accessing to ECMAScript internal fields.
+
+ This change removes accidental [[Put]] operation to an object whose [[Prototype]]
+ has internal fields (not direct properties). By using @getByIdDirectPrivate() and
+ @putByIdDirectPrivate(), we strongly keep the semantics of the ECMAScript internal
+ fields that accessing to the internal fields does not traverse prototype chains.
