tree-vect-data-refs.c (vect_analyze_data_ref_dependences): Assert compute_all_dependences succeeds.
2018-06-29 Richard Biener <rguenther@suse.de>
* tree-vect-data-refs.c (vect_analyze_data_ref_dependences): Assert
compute_all_dependences succeeds.
* tree-vect-loop.c (vect_get_datarefs_in_loop): Fail early if we
exceed --param loop-max-datarefs-for-datadeps.
