未列入数据/数据栏的物体
原标题:Const objects not in rdata/rodata section

I can t force msvc10 to put my const object into .rdata section. It always ends up in .data, perfectly initialised (means there is no dynamic initialisation/runtime constructor execution). (compiled with standard project settings of release build). I dont understand why the following code can t put obj1 into .rdata PE section:

typedef struct _Struct1 {
  int m1;
  _Struct1(int p1): m1(p1) {};
  _Struct1() {};
} Struct1;

class Class1 {
public:
  Class1() {};
  Class1(int p1, int p2): m1(p1), m2_struct(p2) {};
  int m1;
  Struct1 m2_struct;
};

const Class1 obj1(1, 2);

int main() {
  return 0;
}

为什么迷惑不解(由开发协会控制)? 如何在目前情况下迫使它? Tnx.

最佳回答

这些物体有非自食其力的构造者,因此它们必须积极而不是静态地进行初步开发。 因此,它们重新列入<代码>数据一节(所有有活力的初始物体都位于其中,因为其记忆需要在初始阶段变换),尽管汇编者能够优化本案中的施工者呼吁。

实际上,在这种情况下,没有任何东西妨碍汇编者使用<代码>rdata。 只是其发展者没有这样做。
