(vect_vfa_segment_size): Fix indentation. * tree-vectorizer.h (struct _vect_peel_info): New. (struct _vect_peel_extended_info): New. (struct _loop_vec_info): Add new field for peeling hash table and a macro for its access. (VECT_MAX_COST): Define. (vect_get_load_cost): Declare. (vect_get_store_cost, vect_get_known_peeling_cost, vect_get_single_scalar_iteraion_cost): Likewise. (vect_supportable_dr_alignment): Add new argument. * tree-vect-loop.c (new_loop_vec_info): Initialize peeling hash table field. (destroy_loop_vec_info): Free peeling hash table. (vect_analyze_loop_form): Update call to builtin_vectorization_cost. (vect_analyze_loop): Move vect_enhance_data_refs_alignment before vect_analyze_slp. Fix indentation. (vect_get_single_scalar_iteraion_cost): New function. (vect_get_known_peeling_cost): Likewise. (vect_estimate_min_profitable_iters): Rename byte_misalign to npeel. Call vect_get_single_scalar_iteraion_cost instead of cost_for_stmt per statement. Move outside cost calculation inside unknown peeling case. Call vect_get_known_peeling_cost for known amount of peeling. * tree-vect-data-refs.c (vect_compute_data_ref_alignment): Add data reference to the print message of forced alignment.

(vect_enhance_data_refs_alignment): Fix documentation. Use hash table to store all the accesses in the loop and find best possible access to align using peeling for known alignment case. For unknown alignment check if stores are preferred or if peeling is worthy. (vect_find_same_alignment_drs): Analyze pairs of loads too. (vect_supportable_dr_alignment): Add new argument and check aligned accesses according to it. * tree-vect-stmts.c (vect_get_stmt_cost): New function. (cost_for_stmt): Call vect_get_stmt_cost.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
