re PR target/69888 (ICE: SIGSEGV in decide_alg (i386.c:26169) due to infinite (?) recursion with -minline-all-stringops -mmemset-strategy=no_stringop:-1:noalign)
PR target/69888
* config/i386/i386.c (decide_alg): Ensure we don't recurse with
identical arguments. Formatting and spelling fixes.
* gcc.target/i386/pr69888.c: New test.
