Custom Query (245 matches)

A .def file line can exceed 512 bytes when a weak symbol is aliased, an ordinal number is present and weak linker adds '; !weakld changed this!'

In my case I reached around 535 bytes, below patch is slighlty larger :-)

Hi/2.

386/builtin.h includes stdint.h. This may not be a problem on C, however this may be a problem on C++. Because, stdint.h does not define some macros such as INT64_C() on C++ by default. It needs some macros such as __STDC_CONSTANT_MACROS are declared.

So if stdint.h is included once without macro declaration on C++, later macros such as INT64_C() are not declares even if stdint.h is included explicitly.

For example,

#include <vector>
#include <iostream>

#define __STDC_CONSTANT_MACROS
#include <stdint.h>

int main()
{
    std::cout << INT64_C(0) << "\n";

    return 0;
}

This fails.

vector.cpp: In function `int main()':
vector.cpp:9: error: `INT64_C' undeclared (first use this function)
vector.cpp:9: error: (Each undeclared identifier is reported only once for each 
   function it appears in.)

However, this succeeds on other platforms such as mingw-482.
