--- Comment #1 from Kewen Lin <linkw at gcc dot gnu.org> ---
This is a test issue, GCC generates xxspltib rather than vspltis[whb] for const
vector. The below patch can fix it:

-/* { dg-final { scan-assembler-times {\mvspltis[whb] [^\n\r]*,-1\M} 9 } } */
+/* { dg-final { scan-assembler-times {\mvspltis[whb] [^\n\r]*,-1\M|\mxxspltib
[^\n\r]*,255\M} 9 } } */

    testsuite: Adjust pr101384-2.c for Power9 [PR108813]

    Compiled with cpu type Power9 or later, GCC generates
    xxspltib rather than vspltis*, so adjust the test
    case scanning content accordingly.

    gcc/testsuite/ChangeLog:

            * gcc.target/powerpc/pr101384-2.c: Adjust with xxspltib.

Should be fixed on trunk.
