            Bug ID: 193275
           Summary: Support callee-saved floating point registers in DFG
                    for 32-bit platforms
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Other
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dinfuehr at igalia.com

DFG only supports general-purpose callee-saved registers but not floating-point registers in DFGOSRExit.cpp on 32-bit architectures. Extend functions `restoreCalleeSavesFromVMEntryFrameCalleeSavesBuffer` and `copyCalleeSavesToVMEntryFrameCalleeSavesBuffer` to support floating-point registers as well.
