           Summary: JS is not properly executed with JIT enabled on ARM
                    platform
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
               URL: http://www.hotels.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kasibhatla.ravi at gmail.com


In some of the sites the javascript is not executed/properly executed when JIT
is turned on for ARM platform. Some of the actions/requests to be performed by
the javascript are not executed only when JIT is turned on ARM platform. 

For example, in the website http://www.hotels.com, javascript executes in
background which suggests the names of the hotels, as we are typing the string.
In the arm build with jit on, the script doesn't executes at all, hence no
suggestion popup list is shown.
Similar usecases are the chrome experiments
http://open.adaptedstudio.com/html5/many-lines/index.html and
http://tom.drastic.net/twitterbrowse/, where the content is not shown
completely (as shown in PC build).

The build used for the testing of above sites:
Nightly build: WebKit-r49929 (turned on JIT for ARM platform in this build).

OS: Linux (Linux qemu 2.6.21.7-moko11)
Platform: ARM v4
