Relax cgraph_node::clone_of_p to also look through former clones
2019-03-07 Martin Jambor <mjambor@suse.cz>
PR ipa/88235
* cgraph.h (cgraph_node): New inline method former_thunk_p.
* cgraph.c (cgraph_node::dump): Dump a note if node is a former thunk.
(clone_of_p): Treat expanded thunks like thunks, be optimistic if they
have multiple callees. At the end check if declarations match as
opposed to cgraph_nodes.
testsuite/
* g++.dg/ipa/pr88235.C: New test.
