    • A method and apparatus for supporting speculative execution of count and link register modifying instructions in a microprocessor is provided. The apparatus includes a queue of rename buffers storing count/link register operand data resulting from speculatively executed instructions that modify a count/link register. The queue contains a set of control buffers, wherein each control buffer contains control bits associated with a rename buffer, the control bits including an instruction identifier tag identifying a speculatively executed instruction, the operand data of the speculatively executed instruction being stored in the associated rename buffer, and an available bit indicating when the operand data no longer needs to be stored in the associated rename buffer. The apparatus control logic sets the control bits for each control buffer, including setting the instruction identifier tag to the value indicated by a dispatch unit, and selectively sets or resets the available bit based on resolution of the speculatively executed instruction.
    • 提供了一种用于在微处理器中支持计数和链接寄存器修改指令的推测执行的方法和装置。 该装置包括一个重命名缓冲器队列,存储由推测性地执行的修改计数/链接寄存器的指令产生的计数/链接寄存器操作数数据。 队列包括一组控制缓冲器,其中每个控制缓冲器包含与重命名缓冲器相关联的控制位,控制位包括标识推测性执行的指令的指令标识符标签,被推测执行的指令的操作数数据存储在相关联的重命名 缓冲区,以及指示何时操作数数据不再需要存储在关联的重命名缓冲区中的可用位。 设备控制逻辑设置每个控制缓冲器的控制位,包括将指令标识符标签设置为由调度单元指示的值,并且基于推测执行的指令的分辨率选择性地设置或复位可用位。
