            Bug ID: 212784
           Summary: [JSC] add DFG/FTL support for defining/updating
                    Private Fields
           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: caitp at igalia.com

Private fields are initially landed with LLInt and partial JIT baseline support via op_put_by_val_direct. The extra semantics are not handled properly in the generic JIT stubs when IC support is given up on, and are also not supported in optimized code.
