This was the most surprising check of TYPE_METHODS. When not optimizing we usethe non-nullness of TYPE_METHODS to figure out if we want to place a non BLKmodestructure into a register. On the grounds that one can't call a member functionwith a register-located object.


That seems overly enthusiastic -- if we're not optimizing, who cares?

(When we zap TYHPE_METHODS we currently set it to error_mark_node, if it wasnon-null, so that this above check will work).


I'd appreciate comment.
