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. Paolo
