Subject: [PATCH] tree-vect-stmts.c (vectorizable_operation): Check both
VEC_WIDEN_MULT_LO_EXPR and VEC_WIDEN_MULT_HI_EXPR optabs.
* tree-vect-stmts.c (vectorizable_operation): Check both
VEC_WIDEN_MULT_LO_EXPR and VEC_WIDEN_MULT_HI_EXPR optabs.
Verify that operand[0]'s mode is TYPE_MODE (wide_vectype).
