有没有大牛帮忙翻译下下面的汇编代码，感激不尽！
procedure _ClearAlpha(Src: Pointer; Count: integer; Value: longword);
asm
{ Clear alpha }
PUSH EDI
MOV EDI, EAX {X}
MOV EAX, ECX {Value}
MOV ECX, EDX {Count}
TEST ECX,ECX
JS @exit
AND EAX, $00FFFFFF
@1:
MOV EDX, [EDI]
AND EDX, $00FFFFFF
CMP EDX, EAX
JNE @2
MOV [EDI], EDX
@2:
ADD EDI, 4
LOOP @1
@exit:
POP EDI
end;
还有一段：

XOR EBX, EBX
XOR EAX, EAX
MOV EBX, W
MOV EAX, Y1

ADD EDI, EAX
ADD EDI, EAX
ADD EDI, EAX
ADD EDI, EAX
MOV EBX, X2
SUB EBX, X1
