I think your best bet is to grep the changelogs for what has changes, 
and see what was done for other ports.  Many target macros have become 
target hooks.  Or, PREDICATE_CODES for example will require you to 
rewrite the r_or_s_operand and s_operand as "define_predicate" RTL; grep 
the ChangeLog for predicates.md.  And so on.
