I do not know how to find nodes reachable from a particular function, either before or after they are finalized. GenerateVarArgsThunk is called after we do EmitGlobalFunctionDefinition on the function we are about to clone. The ReplaceMap holds replaceable forward type declarations, I think? So I can imagine that codegen for a subsequent function might need to create a complete type, even one that is reachable from the function we are about to clone. Of course I find the whole metadata memory management scheme pretty opaque, but this is my best guess about the situation. https://reviews.llvm.org/D37038 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
