           Summary: If we detect that we can use the JIT, don't use
                    computed opcode lookups
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


When building with both interpreter and JIT enabled, we emit bytecode that uses jump locations for opcodes. The JIT then has to decode these into opcodes.

Instead, if we detect that we have both the interpreter and the JIT, and the JIT is enabled, we should opt to use regular opcodes at run-time.
