re PR target/62662 (Miscompilation of Qt on s390x)

2014-09-19  Andreas Krebbel  <Andreas.Krebbel@de.ibm.com>

PR target/62662
* config/s390/s390.c (s390_emit_epilogue): When doing the return
address load optimization force s390_optimize_prologue to leave it
that way.  Only do the optimization if we already decided to push
r14 into a stack slot.
