2016-12-09 Paul Thomas <pault@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 <pault@gcc.gnu.org> PR fortran/44265 * gfortran.dg/char_result_14.f90: New test. * gfortran.dg/char_result_15.f90: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
