        PR tree-optimization/78938
        * tree-vect-stmts.c (vectorizable_condition): For non-masked COND_EXPR
        where comp_vectype is VECTOR_BOOLEAN_TYPE_P, use
        BIT_{NOT,XOR,AND,IOR}_EXPR on the comparison operands instead of
        {EQ,NE,GE,GT,LE,LT}_EXPR directly inside of VEC_COND_EXPR.  Formatting
        fixes.

        * gcc.dg/vect/pr78938.c: New test.
