.data : AT(EXPR) { data_load = LOADADDR(.data); ...} >ram
but of course here I have to calculate EXPR myself.

I think this has been fixed by my 2006-08-23 fold_name change.

I'm not sure that it will have been. Your change altered the !os->load_base case, but with AT> we explicitly set os->load_base to an integer expression.


I committed your new testcases.

Perhaps the -z option isn't needed on this testcase at all. Perhaps that would be a better change. (I'm not sure if I'd need to increase the memory region addresses in the linker script, to cover other targets though.)
