Summary: SquirrelFish: Potential perf issue in
Array.join/toString
Product: WebKit
Version: 526+ (Nightly build)
Platform: All
OS/Version: All
Status: NEW
Keywords: SquirrelFish
Severity: Normal
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org

Due to the way we handle toString and valueOf when Array.toString()/join() (and
other similar native toString impls) we will repeatedly push and pop
registerfiles for each native toString call even though it's not necessary (say
in the case of calling join() or an explicit call to Array.toString() )
