Many of the GOT patterns (and a few others) contained predicates
which were too general. I fixed that a few months ago in the EGCS
development sources. Whether reload should have been able to handle those
cases is a different matter, but I would be interested to see if the
stricter predicates removed the need for the "reload hack".
