        * config/i386/i386.c (decide_alg): Add RECUR argument.  Revert
        2016-02-22 changes, instead don't recurse if RECUR is already true.
        Don't change *dynamic_check if RECUR.  Adjust recursive caller
        to pass true to the new argument.
        (ix86_expand_set_or_movmem): Adjust decide_alg caller.

        * gcc.target/i386/pr70062.c: New test.
