Hi!

I'm not really a gcc-wizard.  I suppose you just said that the code for 
this bug isn't even supposed to compile.  Can I ask why?  The typedef 
worked fine when I put it in global scope...

Regards,
Stefaan

Stefaan, 
the audit trail of this report seems to have dropped a message since I can't figure out 
to which question you were answering. Can you post this question? 
 
If you meant my confirming message from Feb 5th, I was just confirming that the 
bug exists. I think the code should compile. 
 
W.

Maybe I misinterpret the "wrong-code" flag somehow?

wrong-code means that gcc is generating incorrect assembler code for valid input. This 
is certainly not the case here, since it doesn't generate any code at all. I've removed 
the flag again.

I would like to point out that the bug still exists in gcc 3.4.0 release and
3.5.  Here's another testcase:

struct A
{
  typedef int v2si __attribute__((mode(V2SI)));
  static void f(v2si& v) {
    v2si a;
    v = a;
  }
};

typedef int v2si __attribute__((mode(V2SI)));
int main()
{
  v2si x;
  A::f(x);
}

The bug I reported in #19400, duplicating this one, is fixed in the compiler as of 1/12/04.  However, 
this variant remains busted:

     1  #include <stdio.h>
     2  #include <altivec.h>
     3
     4  template < typename Val > struct S {
     5      typedef vector Val vector_type;
     6      void pr_size() { printf ("size = %d\n", sizeof(vector_type)); }
     7      };  
     8
     9  int main()
    10  {
    11    printf ("size = %d\n", sizeof(S < float >::vector_type));
    12    S<float> x;
    13    x.pr_size();
    14    return 0;
    15  }

because it prints

    size = 4
    size = 4

(In reply to comment #9)
I think that part is more related to PR 17743.  Can you file a new bug, templates are much harder to get 
working with attributes.
