re PR tree-optimization/50819 (missed SLP vectorization)
PR tree-optimization/50819
* tree-vectorizer.h (vect_analyze_data_ref_dependences): Remove
the last argument.
* tree-vect-loop.c (vect_analyze_loop_2): Update call to
vect_analyze_data_ref_dependences.
* tree-vect-data-refs.c (vect_analyze_data_ref_dependence):
Remove the last argument. Check load-after-store dependence
for unknown dependencies in basic blocks.
(vect_analyze_data_ref_dependences): Update call to
vect_analyze_data_ref_dependences.
* tree-vect-patterns.c (vect_recog_widen_shift_pattern): Fix
typo.
* tree-vect-slp.c (vect_bb_vectorizable_with_dependencies):
Remove.
(vect_slp_analyze_bb_1): Update call to
vect_analyze_data_ref_dependences. Don't call
vect_bb_vectorizable_with_dependencies.
