Example 1 with RegisterSaveLayout

use of jdk.vm.ci.code.RegisterSaveLayout in project graal by oracle.

the class AMD64HotSpotLeaveCurrentStackFrameOp method emitCode.

@Override

    // Restore integer result register.
    final int stackSlotSize = frameMap.getTarget().wordSize;
    Register integerResultRegister = registerConfig.getReturnRegister(JavaKind.Long);

         * All of the register save area will be popped of the stack. Only the return address
         * remains.
         */
