r123910 - in /trunk/gcc: ChangeLog testsuite/Ch...


Author: dorit
Date: Tue Apr 17 08:31:45 2007
New Revision: 123910

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=123910
Log:
        * tree-vectorizer.h (stmt_vec_info_type): Add enum value
        induc_vec_info_type.
        (vectorizable_induction): New function declaration.
        * tree-vect-transform.c (get_initial_def_for_induction): No need to
        check if already vectorized.  Find first place in BB where new stmts
        can be inserted.  Takes only one argument.
        (vectorizable_induction): New function.
        (vect_transform_stmt): Add case for induc_vec_info_type to call
        vectorizable_induction.
        (vect_transform_loop): Consider phis for vectorization.
        * tree-vect-analyze.c (vect_determine_vectorization_factor): Simplify
        condition.
        (analyze_operations): Call vectorizable_induction when analyzing phis.
        Fix comment.
        (vect_mark_stmts_to_be_vectorized): Remove redundant checks.
        (vect_mark_relevant): Include phis in relevance analysis.
        (vect_mark_stmts_to_be_vectorize): Likewise.
        * tree-vect-patterns.c (widened_name_p): Remove obsolete asserts.
