tree-vect-patterns.c (vect_recog_dot_prod_pattern): Fix a bug when checking the dot production pattern.
2013-09-17 Cong Hou <congh@google.com> * tree-vect-patterns.c (vect_recog_dot_prod_pattern): Fix a bug when checking the dot production pattern. The type of rhs operand of multiply is now checked correctly. * gcc.dg/vect/vect-reduc-dot-s16c.c: Add a test case with dot product on two arrays with short and int types. This should not be recognized as a dot product pattern. From-SVN: r202663
