This causes issues though, as some fields used by other parts of the compiler (in this case, specifically 'function_{start,end}_locus') are then not correctly initialised. This patch makes sure that these fields are also read and written. PR c++/113580 gcc/cp/ChangeLog: * module.cc (struct post_process_data): Create. (trees_in::post_decls): Use. (trees_in::post_process): Return entire vector at once. Change overload to take post_process_data instead of tree. (trees_out::write_function_def): Write needed flags from DECL_STRUCT_FUNCTION. (trees_in::read_function_def): Read them and pass to post_process. (module_state::read_cluster): Write flags into cfun. gcc/testsuite/ChangeLog: * g++.dg/modules/pr113580_a.C: New test. * g++.dg/modules/pr113580_b.C: New test.
