[PATCH] Minor readability improvement in vect_pattern_recog{,_1}

[Jakub Jelinek]

Hi!

tree-vectorizer.h already has typedefs for the recog functions,
and using that typedef we can make these two functions slightly more
readable.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

2011-10-06  Jakub Jelinek  <ja...@redhat.com>

        * tree-vect-patterns.c (vect_pattern_recog_1): Use
        vect_recog_func_ptr typedef for the first argument.
        (vect_pattern_recog): Rename vect_recog_func_ptr variable
        to vect_recog_func, use vect_recog_func_ptr typedef for it.
