--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a GNU C testcase which shows the error:
#define vector __attribute__((vector_size(4*sizeof(float))))

typedef vector float v4sf;

v4sf f(int t)
{
  float tt = *(float*)&t;
  float t1 = tt;
  asm("":"+r"(t1));
  return (v4sf){t1,t1,t1,t1};
}

And it shows it is a regression from GCC 11 too.

Also vwcore fixes the issue.
