re PR tree-optimization/91033 (ICE in vect_analyze_loop, at tree-vect-loop.c:2416)
PR tree-optimization/91033 * tree-vectorizer.h (vect_mark_stmts_to_be_vectorized, vect_analyze_data_refs): Add bool * arguments. * tree-vect-data-refs.c (vect_analyze_data_refs): Add fatal argument, if failure is due to scatter/gather, set *fatal to false if non-NULL. * tree-vect-stmts.c (vect_mark_stmts_to_be_vectorized): Likewise. * tree-vect-loop.c (vect_analyze_loop_2): Adjust vect_mark_stmts_to_be_vectorized and vect_analyze_data_refs callers. * tree-vect-slp.c (vect_slp_analyze_bb_1): Adjust vect_analyze_data_refs caller. * gcc.target/i386/pr91033.c: New test.
