fields in stmt_vec_info struct and access functions for the same.
(TARG_COND_BRANCH_COST): Define cost of conditional branch.

check to evaluate if loop iterations are less than minimum profitable
iterations determined by cost model or minimum vect loop bound defined
by user, whichever is more conservative.
* tree-vect-transform.c (vect_do_peeling_for_loop_bound): Add a
run-time check to evaluate if loop iterations are less than minimum
profitable iterations determined by cost model or minimum vect loop
bound defined by user, whichever is more conservative.
(vect_estimate_min_profitable_iterations): New function to estimate
mimimimum iterartions required for vector version of loop to be
profitable over scalar version.

(vect_model_induction_cost): New function.
(vect_model_simple_cost): New function.
(vect_cost_strided_group_size): New function.
(vect_model_store_cost): New function.
(vect_model_load_cost): New function.
(vectorizable_reduction): Call vect_model_reduction_cost during
analysis phase.
(vectorizable_induction): Call vect_model_induction_cost during
analysis phase.
(vectorizable_load): Call vect_model_load_cost during analysis phase.
(vectorizable_store): Call vect_model_store_cost during analysis phase.
(vectorizable_call, vectorizable_assignment, vectorizable_operation,
vectorizable_promotion, vectorizable_demotion): Call
vect_model_simple_cost during analysis phase.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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*.
