--- Comment #1 from Alan Modra <amodra at gmail dot com> 2010-11-21 23:09:13 UTC --- I believe this code size regression is due to the fix for #32698. Before that change, gcc calculated the offset for accessing the array elements as n*4 64+n*4 128+n*4 After, we get n*4 (n+16)*4 (n+32)*4 and cse doesn't see the optimization opportunity.
