Patch at
  http://gcc.gnu.org/ml/gcc-patches/2010-03/msg01536.html

Only tested on ARM (same issue as PR42496), but should also solve the ia64
problem.

The resulting code is much better with --param min-crossjump-insns=1.

One possible fix would be to look for common tail (and head?) sequences 
in cond_exec_process_if_block.  The code for tail merging in cfgcleanup.c 
could be used for this.
