r175102 - in /trunk/gcc: ChangeLog testsuite/Ch...


Author: irar
Date: Thu Jun 16 12:08:37 2011
New Revision: 175102

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=175102
Log:

        * tree-vectorizer.h (vect_recog_func_ptr): Change the first
        argument to be a VEC of statements.
        * tree-vect-loop.c (vect_determine_vectorization_factor):
        Remove the assert that pattern statements have to have their
        vector type set.
        * tree-vect-patterns.c (vect_recog_widen_sum_pattern):
        Change the first argument to be a VEC of statements.  Update
        documentation.
        (vect_recog_dot_prod_pattern, vect_recog_pow_pattern): Likewise.
        (vect_handle_widen_mult_by_const): New function.
        (vect_recog_widen_mult_pattern):  Change the first argument to
        be a VEC of statements.  Update documentation.  Check that the
        constant is INTEGER_CST.  Support multiplication by a constant
        that fits an intermediate type - call
        vect_handle_widen_mult_by_const.
        (vect_pattern_recog_1): Update vect_recog_func_ptr and its
        call.  Handle additional pattern statements if necessary.
