Hi, In gccint, 7.2.3.3 Vector-specific attributes, there are two items talking about vect_int_mult:
vect_int_mult Target supports a vector widening multiplication of short operands into an int result, or supports promotion (unpacking) from short to int and a non-widening multiplication of int. vect_int_mult Target supports vector int multiplication. I suspect that the first one should refer to vect_widen_mult_hi_to_si. Thanks Eric
