            Bug ID: 168789
           Summary: B3 should have a sane double-to-int opcode that
                    behaves like JS
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: fpizlo at apple.com

This way, B3 could constant-fold silly cases of this.  Also, it can be instruction-selected very nicely on some CPUs.
