           Summary: DFG JIT should inline Math.abs
           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


Math.abs is a simple function to inline.  We know exactly what it does.  DFG already has the ability to speculate that it is definitely calling a particular function, thanks to CheckMethod.  Implementing this feature will be a great first step for supporting inlining in general, and other sorts of intrinsic functions in particular.
