--- Comment #1 from Kewen Lin <linkw at gcc dot gnu.org> ---
These new failures are expected since the typos for target selector which are
fixed by this commit made these cases pass unexpectedly before (that is running
on powerpc without any selector). I would mark this as duplicated of PR102658.
The posted patch for PR102658 can fix these failures.
