Fusing two loops

[Sandeep Maram]

Hi,

I am trying to fuse two loops in tree level. For that, I am trying to
transfer statements in the header of one loop to the header of the
other one.
The  code   " http://rafb.net/p/fha0IG57.html "  contains the 2 loops.
After moving a statement from one BB to another BB, do I need to
update any other info?
 I need to transfer all the statements of bb_6 to bb_3. Can any one
please tell me what is the exact procedure.
Can i simply use add_bb_to_loop() and add bb_6 to loop_1 ?

Thanks,
Sandeep.
