Fix PR45199: do not aggregate memory accesses to the same array for -ftree-loop-distribute-patterns
2010-11-30 Sebastian Pop <sebastian.pop@amd.com>
PR tree-optimization/45199
* tree-data-ref.c (mem_write_stride_of_same_size_as_unit_type_p): New.
(stores_zero_from_loop): Call
mem_write_stride_of_same_size_as_unit_type_p.
* tree-data-ref.h (stride_of_unit_type_p): New.
* tree-loop-distribution.c (generate_memset_zero): Simplified.
Call stride_of_unit_type_p.
(build_rdg_partition_for_component): Do not call
rdg_flag_similar_memory_accesses when
flag_tree_loop_distribute_patterns is set.
* gcc.dg/tree-ssa/ldist-15.c: New.
* gcc.dg/tree-ssa/ldist-16.c: New.
