            Bug ID: 154828
           Summary: B3::fixSSA() has problems in Octane/regexp
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

          Reporter: fpizlo at apple.com

Usually you know that everything is OK when the compiler spends 95% of its time in IRC.  But in Octane/regexp, this is not the case!  We spent lots of time in fixSSA() instead.  That usually means a scalability problem in that phase.

I've known for a while now that our SSA conversion has scalability problems, and it looks like we're now seeing this.

Note: I don't think that this is actually bottlenecking Octane/regexp performance.  So it's not a high priority right now.
