c++ - Visual C++ 是否提供与 GCC 中的 `__attribute__((alias))` 具有相同功能的语言结构？

Question

__attribute__((alias)) means:

alias ("target")

The alias attribute causes the declaration to be emitted as an alias for another symbol, which must be specified. For instance,

  void __f () { /* Do something. */; }
  void f () __attribute__ ((weak, alias ("__f")));

defines f to be a weak alias for __f. In C++, the mangled name for the target must be used. It is an error if __f is not defined in the same translation unit.

Not all target machines support this attribute.

Answer 1

您可以为 C 执行类似的操作。对于 msvc v19.15，x86 和 x64 支持此操作。

#include <stdio.h>

void __f() { puts("This function is aliased"); }

void f();

#pragma comment(linker, "/alternatename:f=__f")

int main()
{
    f();
}

我已经在 Visual Studio 2017 中使用 /TC 选项对此进行了测试。
