+       * cgraph.c (hash_node, eq_node, cgraph_node, cgraph_remove_node)
+       (cgraph_varpool_hash_node, eq_cgraph_varpool_node)
+       (cgraph_varpool_node): Hash on the pointer to the decl, not
+       the DECL_UID.  Fixes 64-bit bootstrap failure.

As far as I can tell, this patch is just plain wrong.  You can't make
hashes based on pointers that are saved by PCH unless you either (a)
arrange for them to be reordered before writing the PCH, or (b) don't
mind getting a 'not found' result when the data is actually in the
hash table.
