PR target/70062
* 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.
