re PR tree-optimization/56933 (Vectorizer missing read-write dependency for interleaved accesses)
2013-04-15 Richard Biener <rguenther@suse.de>
PR tree-optimization/56933
* tree-vectorizer.h (struct _stmt_vec_info): Remove read_write_dep
member.
(GROUP_READ_WRITE_DEPENDENCE): Remove.
(STMT_VINFO_GROUP_READ_WRITE_DEPENDENCE): Likewise.
* tree-vect-data-refs.c (vect_analyze_group_access): Move
dependence check ...
vect_analyze_data_ref_dependence (vect_analyze_data_ref_dependence):
... here.
* tree-vect-stmts.c (new_stmt_vec_info): Do not initialize
GROUP_READ_WRITE_DEPENDENCE.
* gcc.dg/vect/pr56933.c: New testcase.
