--- Comment #18 from Paul Thomas <pault at gcc dot gnu.org> --- Author: pault Date: Fri Dec 9 11:55:27 2016 New Revision: 243478 URL: https://gcc.gnu.org/viewcvs?rev=243478&root=gcc&view=rev Log: 2016-12-09 Paul Thomas <pa...@gcc.gnu.org> PR fortran/44265 * gfortran.h : Add fn_result_spec bitfield to gfc_symbol. * resolve.c (flag_fn_result_spec): New function. (resolve_fntype): Call it for character result lengths. * symbol.c (gfc_new_symbol): Set fn_result_spec to zero. * trans-decl.c (gfc_sym_mangled_identifier): Include the procedure name in the mangled name for symbols with the fn_result_spec bit set. (gfc_finish_var_decl): Mark the decls of these symbols appropriately for the case where the function is external. (gfc_get_symbol_decl): Mangle the name of these symbols. (gfc_create_module_variable): Allow them through the assert. (gfc_generate_function_code): Remove the assert before the initialization of sym->tlink because the frontend no longer uses this field. * trans-expr.c (gfc_map_intrinsic_function): Add a case to treat the LEN_TRIM intrinsic. (gfc_trans_string_copy): Deal with Wstringop-overflow warning that can occur with constant source lengths at -O3. 2016-12-09 Paul Thomas <pa...@gcc.gnu.org> PR fortran/44265 * gfortran.dg/char_result_14.f90: New test. * gfortran.dg/char_result_15.f90: New test.
