I am creating a few functions at compile time, via a gcc plugin. I create the functions and their bodies, and insert them into the call graph. This is all done before "cgraph_finalize_compilation_unit()" has been called. I then have another compiler pass, which gets started after the SSA representation has been generated, and it is this pass that uses the functions created previously, in the much earlier pass. The problem is that by the time the created functions are used, the cgraph has already removed those nodes since they are disjoint. I tried creating and modifying the functions in the same pass, but that was not successful either. I did not see any flag I could set in the cgraph nodes, which are created in the first pass I mentioned preventing them from being removed. Is there a way I can keep those nodes around so the functions created at compile time actually get built?
