            Bug ID: 237842
           Summary: [JSC] Make op_wide16 and op_wide32 toggles
           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: rmorisset at apple.com

Currently op_wide16 and op_wide32 only apply to the next instruction. But looking at examples, they often seem to be repeated for every instruction in some large sequence.
So I'd like to test having op_toggle8, op_toggle16, op_toggle32, that apply to all instructions until the next toggle. It should both save some memory and ideally some dispatching overhead.
