Hi,

The patch splits the live_edge for move_insn_for_shrink_wrap to sink
the copy out of the entry block.

Bootstrap and no make check regression on X86-64 and ARM.

OK for trunk?

Thanks!

ChangeLog:
2014-05-08  Zhenqiang Chen  <zhenqiang.c...@linaro.org>

          * function.c (next_block_for_reg): Allow live_edge->dest has two
          predecessors.
          (move_insn_for_shrink_wrap): Split live_edge.
          (prepre_shrink_wrap): One more parameter for
move_insn_for_shrink_wrap.

OK.
