--- Comment #3 from Jan Hubicka <hubicka at ucw dot cz> 2011-06-18 09:00:22 UTC --- Hi, the problem is in cgraph_only_called_directl_p call within call_abi_of_interest. Getting the one can probably fix the problem by: Index: rs6000.c =================================================================== --- rs6000.c (revision 175166) +++ rs6000.c (working copy) @@ -7419,7 +7419,7 @@ call_ABI_of_interest (tree fndecl) /* Interesting functions that we are emitting in this object file. */ c_node = cgraph_get_node (fndecl); - return !cgraph_only_called_directly_p (c_node); + return !cgraph_only_called_directly_p (cgraph_function_or_thunk_node (c_node, NULL)); } return false; } however I can't make sense of the logic here. Doesn't it want to use c_node->local && c_node->can_change_signature like other ABI change issues? It makes it possible to use modified ABI cross ltrans partitions. Honza
