Fix PR43023: fuse_partitions_with_similar_memory_accesses.
2010-12-10 Sebastian Pop <sebastian.pop@amd.com>
PR tree-optimization/43023
* tree-data-ref.c (mem_write_stride_of_same_size_as_unit_type_p):
Removed.
(stores_zero_from_loop): Call stmt_stores_zero.
* tree-data-ref.h (stmt_stores_zero): New.
* tree-loop-distribution.c (generate_memset_zero): Do not return a
boolean. Call gcc_assert on stride_of_unit_type_p.
(generate_builtin): Call stmt_stores_zero.
(rdg_flag_all_uses): Removed.
(rdg_flag_similar_memory_accesses): Removed.
(build_rdg_partition_for_component): Removed parameter
other_stores. Removed call to rdg_flag_similar_memory_accesses.
(can_generate_builtin): New.
(similar_memory_accesses): New.
(fuse_partitions_with_similar_memory_accesses): New.
(rdg_build_partitions): Call
fuse_partitions_with_similar_memory_accesses.
* gfortran.dg/ldist-1.f90: Adjust pattern.
* gfortran.dg/ldist-pr43023.f90: New.
