gcc/ChangeLog:
2007-06-08 Harsha Jagasia <harsha.jagasia@amd.com>
Tony Linthicum <tony.linthicum@amd.com>
* doc/extend.texi: Add fvect-cost-model flag.
* common.opt (fvect-cost-model): New flag.
* tree-vectorizer.c (new_stmt_vec_info): Initialize inside and outside
cost fields in stmt_vec_info struct for STMT.
* tree-vectorizer.h (stmt_vec_info): Define inside and outside cost
fields in stmt_vec_info struct and access functions for the same.
(TARG_COND_BRANCH_COST): Define cost of conditional branch.
(TARG_VEC_STMT_COST): Define cost of any vector operation, excluding
load, store and vector to scalar operation.
(TARG_VEC_TO_SCALAR_COST): Define cost of vector to scalar operation.
(TARG_VEC_LOAD_COST): Define cost of aligned vector load.
(TARG_VEC_UNALIGNED_LOAD_COST): Define cost of misasligned vector load.
(TARG_VEC_STORE_COST): Define cost of vector store.
(vect_estimate_min_profitable_iters): Define new function.
* tree-vect-analyze.c (vect_analyze_operations): Add a compile-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.
* 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_reduction_cost): New function.
(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.
