[2/n] PR85694: Attach a DEF_SEQ only to the original statement
A pattern's PATTERN_DEF_SEQ was attached to both the original statement and the main pattern statement, which made it harder to update later. This patch attaches it to just the original statement. In practice, anything that cared had ready access to both. 2018-06-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vectorizer.h (_stmt_vec_info): Note above pattern_def_seq that the sequence is attached to the original statement rather than the pattern statement. * tree-vect-loop.c (vect_determine_vf_for_stmt): Take the PATTERN_DEF_SEQ from the original statement rather than the main pattern statement. * tree-vect-stmts.c (free_stmt_vec_info): Likewise. * tree-vect-patterns.c (vect_recog_dot_prod_pattern): Likewise. (vect_mark_pattern_stmts): Don't copy the PATTERN_DEF_SEQ. From-SVN: r261785
