--- Comment #8 from Ira Rosen <irar at il dot ibm.com> 2011-06-11 07:54:55 UTC --- Created attachment 24490 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24490 an updated patch I updated your patch: - call vect_is_slp_reduction only if check_reduction is true - removed COND_EXPR and GIMPLE_BINARY_RHS checks - replaced !is_pattern_stmt_p with !STMT_VINFO_IN_PATTERN_P for use_stmt, because we actually want the pattern stmt and not the stmt it replaced Bootstrapped and tested on powerpc64-suse-linux. Thanks, Ira
