Is there any plan for "data propagation from Tree SSA to RTL" to be in GCC mainline?

[Bingfeng Mei]

I found it quite hard to merge the patch into current trunk HEAD since many things has changed.  Do you know which revision you use?  I would like to have a test to see whether it is effective in solving memory dependency issue in SMS. Thanks.
