            Bug ID: 210135
           Summary: [JSC][LLInt] Cache subscript for get_by_val operations
           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: ticaiolima at gmail.com

Currently, we are saving seen identifiers into `get_by_val` and use such information to decide if it is worth it add IC for a given `get_by_val`. However, there is no IC support for cacheable cells on LLInt yet.
