It's probably a good idea to test patches to subreg_get_info on an e500 
target such as powerpc-eabispe.  I don't *think* e500 is doing anything 
that would be affected by the proposed patch, but what it does with 
subregs is fiddly enough (and is the reason for some of the code in 
subreg_get_info) that any changes to subreg_get_info could easily show up 
problems there.
