tree-vectorizer.c: New File: loop vectorization on SSAed GIMPLE trees.
* tree-vectorizer.c: New File: loop vectorization on SSAed GIMPLE trees. * tree-vectorizer.h: New File: Same. * Makefile.in (tree-vectorizer.c, tree-vectorizer.h): Add new files. * common.opt (ftree-vectorize): New flag to enable vectorization. * timevar.def (TV_TREE_VECTORIZATION): New dump file for vectorization pass. * tree-data-ref.h (init_data_ref): Additional argument. (array_base_name_differ_p): Moved to tree-data-ref.c. * tree-data-ref.c (array_base_name_differ_p): Revised. (initialize_data_dependence_relation): Call array_base_name_differ_p with an extra argument. (analyze_all_data_dependences): Same. (init_data_ref): Additional argument is_read to set DR_IS_READ. * tree-ssa-phiopt.c (empty_block_p): Expose for usage out of this file. * tree-flow.h (vectorize_loops, empty_block_p): Add declaration. * tree-optimize.c (pass_vectorize): Schedule the vectorization pass. * tree-pass.h (tree_opt_pass pass_vectorize): Declare the new vectorization pass. * tree-ssa-loop.c (tree_ssa_loop_init): Call scev_initialize. (tree_ssa_loop_done): Call scev_finalize. (tree_vectorize): Define the new vectorization pass. * defaults.h (UNITS_PER_SIMD_WORD): Allow targets to specify the size of the vector they support (until support for multiple vector sizes is added to the vectorizer). * config/i386/i386.h (UNITS_PER_SIMD_WORD): Define. * config/rs6000/rs6000.h (UNITS_PER_SIMD_WORD): Define. * invoke.texi (fdump-tree-vect, ftree-vectorize): Add documentation.
