            Bug ID: 221435
           Summary: [JSC] Add B3::FTrunc
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ysuzuki at apple.com

It is Math trunk(double/float). This is very frequently used one so that we should have that in B3 instead of FTLOutput::doubleTrunc's patchpoint. (If we implement it in B3 opcode, we can drive strength reduction etc.).
