        * config/i386/predicates.md (cmpxchg8b_pic_memory_operand): New
        predicate.
        * config/i386/sync.md (sync_compare_and_swap<mode>,
        sync_compare_and_swap_cc<mode>): For DImode with -m32 -fpic check
        if operands[1] is cmpxchg8b_pic_memory_operand, if not force address
        into a register.
        (sync_double_compare_and_swapdi_pic,
        sync_double_compare_and_swap_ccdi_pic): Require operand 1 to be
        cmpxchg8b_pic_memory_operand instead of just memory_operand.

        * gcc.target/i386/pr39431.c: New test.
