In fact this brings back PR tree-opt/68327 on the 6 branch:

It's rather || STMT_VINFO_LIVE_P in most cases and this works here, the
vectorization is properly blocked:

Yes, for
result_15 = _6 & result_3;
wich is a BIT_AND_EXPR, hence accepted by vectorizable_reduction.

Hi,
it's a regression present on the mainline and 6 branch: for the attached Ada
testcase, optab_for_tree_code segfaults because the function is invoked on a
NULL_TREE vectype_out from the vectorizer (vectorizable_reduction):
if (STMT_VINFO_VEC_REDUCTION_TYPE (stmt_info) == TREE_CODE_REDUCTIO
