--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note the `-m32` part of _mm_blend_pd is fixed in GCC 9+ as we get:
```
In file included from <source>:2:
<source>: In function 'main':
<source>:11:14: error: '__builtin_ia32_blendpd' needs isa option -msse4.1
   11 |  __m128d r = _mm_blend_pd  (a, b, 1);
      |              ^~~~~~~~~~~~

```

Note the error message for _mm_blendv should be improved. I thought there was
another bug about that ...
