        * config/i386/sse.md (vec_extract_lo_<mode><mask_name>): For
        V8FI, V16FI and VI8F_256 iterators, use <store_mask_predicate> instead
        of nonimmediate_operand and <store_mask_constraint> instead of m for
        the input operand.  For V8FI iterator, always split if input is a MEM.
        For V16FI and V8SF_256 iterators, don't test if both operands are MEM
        if <mask_applied>.  For VI4F_256 iterator, use <store_mask_predicate>
        instead of register_operand and <store_mask_constraint> instead of v
for
        the input operand.  Make sure both operands aren't MEMs for if not
        <mask_applied>.

        * gcc.target/i386/pr81225.c: New test.
