(curr_binding_label): Make a pointer rather than static array. (build_sym): Check sym->binding_label pointer rather than array, update set_binding_label call, handle curr_binding_label changes. (set_binding_label): Handle new curr_binding_label, dest_label double ptr, and sym->binding_label. (verify_bind_c_sym): Handle sym->binding_label being a pointer. (set_verify_bind_c_sym): Check sym->binding_label pointer rather than array, update set_binding_label call. (gfc_match_bind_c_stmt): Handle curr_binding_label change. (match_procedure_decl): Update set_binding_label call. (gfc_match_bind_c): Change binding_label to pointer, update gfc_match_name_C call. * gfortran.h (GFC_MAX_BINDING_LABEL_LEN): Remove macro. (gfc_symbol): Make binding_label a pointer. (gfc_common_head): Likewise. * match.c (gfc_match_name_C): Heap allocate bind(C) name. * match.h (gfc_match_name_C): Change prototype argument. (set_binding_label): Move prototype to decl.c. * module.c (struct pointer_info): Make binding_label a pointer. (free_pi_tree): Free unused binding_label. (mio_read_string): New function. (mio_write_string): New function. (load_commons): Redo reading of binding_label. (read_module): Likewise. (write_common_0): Change to write empty string instead of name if no binding_label. (write_blank_common): Write empty string for binding label. (write_symbol): Change to write empty string instead of name if no binding_label. * resolve.c (gfc_iso_c_func_interface): Don't set binding_label. (set_name_and_label): Make binding_label double pointer, use asprintf. (gfc_iso_c_sub_interface): Make binding_label a pointer. (resolve_bind_c_comms): Handle cases if gfc_common_head->binding_label is NULL. (gfc_verify_binding_labels): sym->binding_label is a pointer. * symbol.c (gfc_free_symbol): Free binding_label. (gfc_new_symbol): Rely on XCNEW zero init for binding_label. (gen_special_c_interop_ptr): Don't set binding label. (generate_isocbinding_symbol): Insert binding_label into symbol table. (get_iso_c_sym): Use pointer assignment instead of strcpy. * trans-common.c (gfc_sym_mangled_common_id): Handle com->binding_label being a pointer. * trans-decl.c (gfc_sym_mangled_identifier): Handle sym->binding_label being a pointer. (gfc_sym_mangled_function_id): Likewise. testsuite ChangeLog 2012-01-29 Janne Blomqvist <j...@gcc.gnu.org> PR fortran/51808 * gfortran.dg/module_md5_1.f90: Update MD5 sum.
