Hi,
In testcase cgraph_edge.C, inline_edge_summary in
estimate_function_body_sizes fails because there is no callgraph edge
representing the stmt.
The edge was removed in ipa_tm_transform_calls_redirect after
transforming to indirect call.
Honza: I have added you to this email since Richard was not sure about
edge removal.
Patrick.
