            Bug ID: 171454
           Summary: WebAssembly: make sure tiering can run out of X memory
                    gracefully
           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

If We try to tier up a function but don't have X memory available for it then it should just stay at O1. Slow is better than dead. That's what we do for JS (stay in llint).
