            Bug ID: 180874
           Summary: YARR: JIT RegExps with back references
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: msaboff at apple.com

Currently, patterns with back references, e.g. /(a)\1/, are not supported in the Yarr JIT.  We should add support for some or all back references.  It should be straightforward to support back references without case folding.  JIT support for case folding with 8 bit characters shouldn't be to hard as the case folding table is a reasonable size.  JIT support of 16-bit and/or Unicode patterns will require calling out to C++ for case folding.
