GCC 4.0.0 / 4.0.2 seems to ignore the stdcall (and also fastcall)
attributes when used at static member template functions.
The generated code for the function is incorrect.
Also when taking the address of that function, the type is a pointer to
a "normal" function and not a pointer to a stdcall function. (See example
below). So it seems that the stdcall attribute is "lost" during parsing.
This problem only occurs when using a template function. A static stdcall
function without template works as expected.
#define stdcall __attribute__((stdcall))
struct T {
template <class S>
static int stdcall func(int arg1, int arg2);
};
// The generated assembly is incorrect. Function is not
// removing arguments, so this is clearly not "stdcall"
// ("ret" instruction at the end instead of "ret 0x8")
template <class S>
int stdcall T::func(int arg1, int arg2)
{
return arg1+arg2;
}
struct dummy {};
void xx()
{
int (*ptr)(int,int) = &T::func<dummy>; // works (although
incorrect)
// int (stdcall *ptr2)(int,int) = &T::func<dummy>; // generates error
(although correct)
}
