The precedence shift/reduce resolving system works so that it looks
at the token immediately before the "." in the reduce rule, and the
token immediately after the "." in the shift rule, and use the
defined token precedences (%left, etc.) to make a choice. If your
rules are not on this simple form, it will not work. So then you may
decide to rewrite your grammar.
