Question

我正在尝试使用Visual Studio 2010编译huffyuv。组装asm文件时收到错误消息A2070。我粘贴了以下相关代码（部分）：

YUV_SHIFT   MACRO   mmb,mma,uyvy    ; clobbers mm4,5

; mma:mmb = ABCDEFGHIJKLMNOP (VYUYVYUY...) - backwards from mem order
;   we want mmb = EDGFIHKJ (prev pixel of same channel)

    movq    mm4,mmb
    punpcklbw   mmb,mma     ; mm4:mmb = AIBJCKDLEMFNGOHP
    punpckhbw   mm4,mma
    movq    mm5,mmb
    punpcklbw   mmb,mm4     ; mm5:mmb = AEIMBFJNCGKODHLP
    punpckhbw   mm5,mm4
    movq    mm4,mmb
    punpcklbw   mmb,mm5     ; mm4:mmb = ACEGIKMOBDFHJLNP
    punpckhbw   mm4,mm5
    psllq   mmb,8+8*&uyvy       ; mm4:mmb = EGIKMO__DFHJLNP_
    psllq   mm4,16-8*&uyvy
    punpckhbw   mmb,mm4     ; mmb = EDGFIHKJ (for YUY2; different for UYVY)

    ENDM

MEDIAN_PREDICT_PROC mmx_MedianPredictYUY2,0 ; I get the error on this line
MEDIAN_PREDICT_PROC mmx_MedianPredictUYVY,1 ; and this as well

这是我得到的第一个错误（后来我得到了更多同样的错误，但如果我知道如何修复第一个错误，我可以修复其余的错误。）

我不太了解汇编代码，所以如果有人能告诉我问题在哪里，以及如何解决，我会很高兴。
