[PATCH] [modulo-sched] Change the ddg's construction

[Revital1 Eres]

Hello,

Attached is a patch that should fix the ddg's
construction as described in the RFC message of this patch
and following the comments received.
(http://gcc.gnu.org/ml/gcc-patches/2006-12/msg01682.html
http://gcc.gnu.org/ml/gcc-patches/2006-12/msg01688.html)

This patch was bootstrapped and tested on ppc together
with other previous SMS patches that fix bootstrap failure.
(http://gcc.gnu.org/ml/gcc-patches/2007-01/msg01468.html)

OK for mainline once the previous patches are inserted?

:ADDPATCH modulo-sched:

Thanks,
Revital

          (build_inter_loop_deps): Call add_deps function to build the
