Hi,

instead of selecting bits 62 to (wraparound) 59 from r2 and inserting 
them into r3, we select bits 60 to 62 from r3 and insert them into r2 
nowadays.  Adjust the test accordingly.

Is this OK?

Regards
  Robin

gcc/testsuite/ChangeLog:

         * gcc.target/s390/risbg-ll-3.c: Change match pattern.
