testsuite/117714 - gcc.dg/vect/slp-reduc-4.c FAILs on 32-bit SPARC
The testcase tries to ensure we can elide all permutations when
vectorizing a MAX reduction. For SPARC the issue is that the
MAX reduction isn't supported and since we're trying to fall back
to single-lane SLP the dumps contain VEC_PERM_EXPR for the
interleaving permute lowering. Before all-SLP that wouldn't
be in the dumps when doing non-SLP, but eventually we'd fail to
vectorize so no VEC_PERM_EXPRs would be in the dumps either.
The following adds vect_no_int_min_max to the set of xfails for
this particular scan as well, like the existing check for vectorizing.
PR testsuite/117714
* gcc.dg/vect/slp-reduc-4.c: Add vect_no_int_min_max to the
XFAIL for the VEC_PERM_EXPR scan.
