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.
