Identifying Array References later

[Guilherme Ottoni]

Hi,

I want to implement in GCC an optimization which makes a more efficient
use of address registers with (pre|pos)-(increment|decrement)
facilities. 

The optimization is applied to arrays addressing inside loops, and I
need to keep the array references together (eg, a[i+2]) in the RTL
representation through many compiler passes, until the point where my
optimization will take place. The idea is to make it easier to identify
the array references when needed.

Does anyone have any suggestion on how I can do this?

Thanks,
