           Summary: Architecture specific implementation in DFG could be
                    avoided
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jbriance at cisco.com


When using ARM architecture with HARD_FP, we have FPRInfo::argumentFPR0 == FPRInfo::returnValueFPR == ARMRegisters::d0, so we don't need a specific implementation for this case of the 2 following functions, the fallback one is fine.

  JITCompiler::Call appendCallWithExceptionCheckSetResult(const FunctionPtr& function, FPRReg result)
  JITCompiler::Call appendCallSetResult(const FunctionPtr& function, FPRReg result)
