c++内嵌了一段汇编，有两行编译不过，请大家帮忙看一下

DWORD dwByteTree[765];
WORD wByteTree[765];
char dwBitTree[765];
DWORD dwRootIndex,dwCodeCount,dwStorage;
WORD wTreeSize;

int iElements,iTotalElements;

void HuffmanInitArrays()
{
__asm
{
MOV EDI,OFFSET dwWeight[0] //这句不行
MOV ECX,256
_InitWeight:
MOV DWORD PTR [EDI],0
ADD EDI,4
DEC ECX
JNZ _InitWeight
}

__asm
{
MOV EDI,OFFSET dwBitTree[0] //这句不行
MOV EAX,0
MOV ECX,255
_InitBitTree:
MOV char PTR [EDI + EAX],2
ADD EAX,3
DEC ECX
JNZ _InitBitTree
}
}
