Hello,

Following the fix for the unroller patch
(http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00397.html)
I resubmit the patch for Splitting memory references during unrolling.

Bootstrapped (with -funroll-all-loops) & regression tests on POWER4.

        * loop-unroll.c: (can_split_memory_ref): New function 
          for determine whether the current instruction 
          contains memory reference which uses an 
          induction variable. 
          (analyze_iv_to_split_insn): Expand the function to 
          analyze also instructions of memory references.
