The reason we get into this ICE is because the call to cgraph_edge() has the
side effect of adding entries to e-caller-call_site_hash:
if (n 100)
{
node-call_site_hash = htab_create_ggc (120, edge_hash, edge_eq, NULL);
for (e2 = node-callees; e2; e2 = e2-next_callee)
cgraph_add_edge_to_call_site_hash (e2);
for (e2 = node-indirect_calls; e2; e2 = e2-next_callee)
cgraph_add_edge_to_call_site_hash (e2);
}
When cgraph_edge is called with n 100, the call to
cgraph_add_edge_to_call_site_hash asserts because e-call_stmt is already in
the hash table.
Honza, why is this a problem? The code is expecting to find the slot empty,
but I'm not sure why it expects that. Any pointers?
Thanks. Diego.
