--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
No progress in GCC 9.0. This problem also isn't limited to C++. It affects
all front-ends that support attributes that take arguments. The test case in
comment #0 can be modified to illustrate the same issue in C source code:
$ cat pr70125.C && gcc -S -Wall -xc pr70125.C
void f (void*);
__attribute__ ((always_inline, artificial)) static inline
void g (int N)
{
typedef int V __attribute__ ((vector_size (N)));
V v = { 0 };
f (&v);
}
void h (void)
{
g (16);
g (31);
}
pr70125.C: In function ‘g’:
pr70125.C:6:3: warning: ‘vector_size’ attribute ignored [-Wattributes]
6 | typedef int V __attribute__ ((vector_size (N)));
| ^~~~~~~
