            Bug ID: 193795
           Summary: We should do constant folding on ValueOp even when it
                    is UntypedUse
           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

Right now, we don't do constant fold on ValueOp nodes, but there is no reason why we shouldn't do this, since profiling and prediction propagation can miss some opportunities.
