Fw: [PATCH] Unrolling addressing optimization


Hello,

Attached is the new improved version of the unrolling addressing 
optimization patch.
We added a new functionally which moves the initialization of the base 
addr (addr =&a[i]) to the preheader
during the unrolling.

Bootstrapped & regression tests on POWER4.

Zdenek - l had to change the way the right side of a set rtx is extracted 
in loop-iv.c file
in order to adjust it to the  new functionally. Do you agree with this?

Thanks,
Revital

Hello,

> Attached is the final version of the patch.

you still did not fix the problem with making
duplicate_loop_to_header_edge unrolling specific (i.e. you must also
change this function in a similar way you did with copy_bbs).
