        PR tree-optimization/91003
        * tree-vect-slp.c (vect_mask_constant_operand_p): Pass in the
        operand number, avoid handling the non-condition operands of
        COND_EXPRs as comparisons.
        (vect_get_constant_vectors): Pass down the operand number.
        (vect_get_slp_defs): Likewise.

        * gfortran.dg/pr91003.f90: New testcase.
