Summary: DFG does worse than the old JIT for virtual calls
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
The DFG calls to a C function to do virtual calls, while the old JIT calls a JIT-generated thunk. The DFG should try to perform at least as well as the old JIT for virtual calls.
