Well, in my patch that check was guarded by the if (slp_node ...),
so presumably it would allow modifier == NARROW vectorization in the loops
(otherwise some testcases would fail I'd hope).
Is gcc_assert ((slp_node != NULL) == (STMT_SLP_TYPE (stmt_info) != 0));
always true? If not, when it is not? When would be slp_node == NULL
and PURE_SLP_STMT true?
