不幸的是,我不得不重新映像我的笔记本电脑以安装 Visual Studio 2012。我的项目构建但出现上述警告。以前我有 Visual Studio 2010,但从未收到上述警告。代码如下:
__asm
{
//Initialize pointers on matrices
mov eax, dword ptr [this]
mov ebx, dword ptr [eax+UPkk]
mov dword ptr [UPkk_ptr],ebx
mov ebx, dword ptr [eax+UPk1k]
mov dword ptr [UPk1k_ptr],ebx
mov ebx, dword ptr [eax+DPk1k]
mov dword ptr [DPk1k_ptr],ebx
mov ebx, dword ptr [eax+DPkk]
mov dword ptr [DPkk_ptr],ebx
mov ebx, dword ptr [eax+mat_A]
mov dword ptr [mat_A_ptr],ebx
mov ebx, dword ptr [eax+vec_a]
mov dword ptr [vec_a_ptr],ebx
mov ebx, dword ptr [eax+vec_b]
mov dword ptr [vec_b_ptr],ebx
}
我需要更改项目中的任何设置吗?
最好的祝福

编辑:在上面的代码中,当我用 ecx 替换 ebx 时,警告消失并且代码工作正常。但是,我在另一段代码中使用了 ebx 和 ecx,在这种情况下我的程序崩溃了。这是代码:
__asm
{
//Initialize UPk1k[idx_4] pointer
mov eax, dword ptr [UPk1k_ptr]
mov ebx, dword ptr [idx_4]
imul ebx,8
add eax,ebx
mov dword ptr [UPk1k_id4_ptr],eax
//Initialize UPkk[idx_4] pointer
mov eax, dword ptr [UPkk_ptr]
mov ebx, dword ptr [idx_4]
imul ebx,8
add eax,ebx
mov dword ptr [UPkk_id4_ptr],eax
//Initialize UPk1k[idx_4] pointer
mov eax, dword ptr [vec_b_ptr]
mov ebx, dword ptr [idx_1]
imul ebx,8
add eax,ebx
mov dword ptr [vec_b_id1_ptr],eax
mov edi, dword ptr [idx_1] //Load idx_1 in edi
mov esi, 0 //initialize loop counter
jmp start_proc11
start_for11:inc esi //idx_2++
start_proc11:cmp esi, edi //idx_2<idx_1 ?
jge end_for11 //If yes so end of the loop
mov eax, UPk1k_id4_ptr //load UPk1k[idx_4] adress
mov ebx, vec_b_ptr //load vec_b adress
mov ecx, esi
imul ecx,8
add eax, ecx //UPk1k[idx_4+idx_2] in eax
add ebx, ecx //vec_b[idx_2] in eax
fld qword ptr [eax]//push UPk1k[idx_4+idx_2]
fld qword ptr [ebx] //push vec_b[idx_2]
mov edx,dword ptr [Sd_ptr]
fmul qword ptr [edx] //vec_b[idx_2]*Sd
fadd //pop UPk1k[idx_4+idx_2]+vec_b[idx_2]*Sd
mov edx,dword ptr [UPkk_id4_ptr]
fstp qword ptr [edx+esi*8] //pop UPkk[idx_4+idx_2]=UPk1k[idx_4+idx_2]+vec_b[idx_2]*Sd
fld qword ptr [ebx] //push vec_b[idx_2]
mov edx,dword ptr [vec_b_id1_ptr]
fld qword ptr [edx] //push vec_b[idx_2]
fmul qword ptr [eax]
fadd
fstp qword ptr [ebx]
jmp start_for11 //end of the loop
end_for11:
}
非常感谢
最好的祝福
