[Gcc4cli-devel] static vararg?

[Erven R. <erv...@in...>]

Ciao a tutti,

the following piece of code does not link when -DBUG is passed (ie when the 
vararg method is static): "Error: Can't find method: foo"
This vaguely reminds me something. Is it just me? Do you also remember a problem 
like this?

[Note: this is cc.c-torture/execute/va-arg-11.c]

Thanks,

#include <stdarg.h>
#include <stdlib.h>

#ifdef BUG
static
#endif
int foo (int a, ...)
{
   va_list va;
   int i, res;

   va_start (va, a);

   for (i = 0; i < 4; ++i)
     (void) va_arg (va, int);

   res = va_arg (va, int);
   va_end (va);
   return res;
}

int
main (void)
{
   if (foo (5, 4, 3, 2, 1, 0))
     abort ();
   exit (0);
}

If I recall it correctly it is an error of ilasm, it does not
recognize the signature correctly.
I think I inserted it in novell bugzilla, but I am not sure.

I remember that Dotgnu had the same problem
and I have a hack in the mono linker for it.
(the difference is that Dotgnu generates an incomplete assembly that I
can fix, mono ilasm just breaks)

Hi Andrea,

I checked all the bug you entered in the Novell Bugzilla. Several seem related 
(pinvoke varargs, or vararg fun called without parameters), but I could not find 
this one. Do you mind taking a look? If it is not entered, I'll submit it.

But how can you tell it is ilasm? When I disassemble the .o (cil32-objdump or 
parse.NET), the only difference I can see it the flag of method foo: private or 
public.

For the record: I think Andrea convinced himself that it could be a problem in 
our linker.
