--- Comment #17 from Richard Biener <rguenth at gcc dot gnu.org> ---
Same for

 #define VECT_SCALAR_BOOLEAN_TYPE_P(TYPE) \
-  (INTEGRAL_TYPE_P (TYPE)               \
-   && TYPE_PRECISION (TYPE) =3D=3D 1)
+  ((TREE_CODE (TYPE) =3D=3D BOOLEAN_TYPE           \
+    && TYPE_PRECISION (TYPE) =3D=3D 1)             \
+   || ((TREE_CODE (TYPE) =3D=3D INTEGER_TYPE       \
+       || TREE_CODE (TYPE) =3D=3D ENUMERAL_TYPE)   \
+       && TYPE_PRECISION (TYPE) =3D=3D 1           \
+       && TYPE_UNSIGNED (TYPE)))

so we do need to understand the Ada failure instead for which again I'm hop=
ing
for a (LTO) testcase.  I'm not too familiar with the vector boolean pattern
stuff so I'm not the appropriate person to dig into this.

At least it seems this VECT_SCALAR_BOOLEAN_TYPE_P predicate is very much
fragile.=
