re PR fortran/36704 (Procedure pointer as function result)
2009-04-09 Janus Weil <janus@gcc.gnu.org> PR fortran/36704 * decl.c (add_hidden_procptr_result): New function for handling procedure pointer return values by adding a hidden result variable. (variable_decl,match_procedure_decl,gfc_match_function_decl, gfc_match_subroutine,gfc_match_end,attr_decl1): Handle procedure pointer return values. * parse.c (parse_interface): Add EXTERNAL attribute only after FUNCTION/SUBROUTINE declaration is complete. * primary.c (replace_hidden_procptr_result): New function for replacing function symbol by hidden result variable. (gfc_match_rvalue,match_variable): Replace symbol by hidden result variable. * resolve.c (resolve_contained_fntype,resolve_function,resolve_variable, resolve_symbol): Allow for procedure pointer function results. (resolve_fl_procedure): Conflict detection moved here from 'check_conflict'. * symbol.c (gfc_check_function_type): Allow for procedure pointer function results. (check_conflict): Move some conflict detection to resolution stage. * trans-types.c (gfc_sym_type,gfc_get_function_type): Handle hidden result variables. 2009-04-09 Janus Weil <janus@gcc.gnu.org> PR fortran/36704 * gfortran.dg/external_procedures_1.f90: Modified. * gfortran.dg/proc_ptr_result_1.f90: New. * gfortran.dg/proc_ptr_result_2.f90: New. * gfortran.dg/proc_ptr_result_3.f90: New.
