- * tree-flow.h (stmt_ann_d): Move aux to ...
- (tree_ann_common_d): ... here.
- * tree-ssa-loop-im.c (LIM_DATA, determine_invariantness_stmt,
- move_computations_stmt, schedule_sm): Update references to
- aux.
- * tree-vectorizer.h (set_stmt_info, vinfo_for_stmt): Likewise.
- * tree-vect-transform.c (vect_create_index_for_vector_ref): Update
- call to set_stmt_info.
- (vect_transform_loop): Likewise.
- * tree-vectorizer.c (new_loop_vec_info, destroy_loop_vec_info):
- Likewise.
-
- * tree-vect-analyze.c (vect_analyze_scalar_cycles): Made void instead of
- bool.
- (vect_mark_relevant): Takes two additional arguments - live_p and
- relevant_p. Set RELEVANT_P and LIVE_P according to these arguments.
- (vect_stmt_relevant_p): Differentiate between a live stmt and a
- relevant stmt. Return two values = live_p and relevant_p.
- (vect_mark_stmts_to_be_vectorized): Call vect_mark_relevant and
- vect_stmt_relevant_p with additional arguments. Phis are no longer
- put into the worklist (analyzed seperately in analyze_scalar_cycles).
- (vect_determine_vectorization_factor): Also check for LIVE_P, because a
- stmt that is marked as irrelevant and live, cause it's only used out
- side the loop, may need to be vectorized (e.g. reduction).
- (vect_analyze_operations): Examine phis. Call
- vectorizable_live_operation for for LIVE_P stmts. Check if
- need_to_vectorize.
- (vect_analyze_scalar_cycles): Update documentation. Don't fail
- vectorization - just classify the scalar cycles created by the loop
- phis. Call vect_is_simple_reduction.
- (vect_analyze_loop): Call to analyze_scalar_cycles moved earlier.
- * tree-vect-transform.c (vect_create_index_for_vector_ref): Update
- call to set_stmt_info.
- (vect_get_vec_def_for_operand): Code reorganized - the code that
- classifies the type of use was factored out to vect_is_simple_use.
- (vectorizable_store, vect_is_simple_cond): Call vect_is_simple_use with
- additional arguments.
- (vectorizable_assignment): Likewise. Also make sure the stmt is relevant
- and computes a loop_vec_def.
- (vectorizable_operation, vectorizable_load, vectorizable_condition):
- Likewise.
- (vectorizable_live_operation): New.
- (vect_transform_stmt): Handle LIVE_P stmts.
- * tree-vectorizer.c (new_stmt_vec_info): Initialize the new fields
- STMT_VINFO_LIVE_P and STMT_VINFO_DEF_TYPE.
- (new_loop_vec_info, destroy_loop_vec_info): Also handle phis.
- (vect_is_simple_use): Determine the type of the def and return it
- in a new function argument. Consider vect_reduction_def and
- vect_induction_def, but for now these are not supported.
- (vect_is_simple_reduction): New. Empty for now.
- * tree-vectorizer.h (vect_def_type): New enum type.
- (_stmt_vec_info): Added new fields - live and _stmt_vec_info.
- (STMT_VINFO_LIVE_P, STMT_VINFO_DEF_TYPE): New accessor macros.
- (vect_is_simple_use): New arguments added to function declaration.
- (vect_is_simple_reduction): New function declaration.
