Hello,
This patch adds use-def chain problem to SMS as described in -
http://gcc.gnu.org/ml/gcc/2007-10/msg00368.html
Bootstrapped and tested on SPU and x86. Currently testing it on ppc
(only c,c++ and fortran due to recent errors in libjava).
:ADDPATCH modulo-sched:
OK for mainline once the testing completes?
Thanks,
Revital
