--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

It also happens for aarch64 with:
```
#include <arm_sve.h>

int __attribute__((target ("+sve"), optimize(3)))
bar (void)
{
  svfloat32_t xseg;
  return svlen_f32(xseg);
}
```

Which makes me think this is not target specific. Same behavior at x86_64
testcase with the optimization levels too.
