--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
This is also the FAIL of

FAIL: gcc.target/i386/vect-gather-1.c scan-tree-dump vect "loop vectorized"

with -m32 testing.  Note the intent was to have the testcase work independent
on the presence of HW gather (for you folks testing with -march=cascadelake).

The XFAIL condition is going to be tricky for this so I'll leave this test
FAILing at least until I can decide whether fixing the missing feature is
possible for GCC 12.
