re PR middle-end/53409 (ICE: vector VEC(vec_void_p,base) index domain error, in vinfo_for_stmt at tree-vectorizer.h:630)
PR tree-optimization/53409
* tree-vect-loop.c (vect_analyze_loop_operations): Don't check
vinfo_for_stmt (op_def_stmt) if op_def_stmt isn't inside loop.
* gcc.c-torture/compile/pr53409.c: New test.
