            Bug ID: 214491
           Summary: REGRESSION(r264330): infinite loop in JSC stress tests
                    using cloop
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at gnome.org

r264330 added an infinite loop that was supposed to be broken by the --returnEarlyFromInfiniteLoopsForFuzzing=true flag. However, it doesn't work when the tests are run with cloop. This has caused JSC stress tests to run forever only on x86_64 (with cloop enabled). Instead of skipping the tests on particular architectures, let's run the loops only if $vm.useJIT(), suggested by Yusuke.

I think there is a problem with architecture detection for arm64, because the tests are still running fine on this architecture.
