While testing the --with-documentation-root-url= changes, I run into [Wreturn-type] URL pointing to gfortran documentation where it obviously isn't documented. The following patch updates the list of options to match reality (on the other side -Wconversion-extra is gfortran only option documented in gfortran.texi). Or, perhaps better use the attached patch instead, which doesn't have a hardcoded list and instead uses the flags? I went through options.c and the updated list of options matches exactly the cases where CL_Fortran is set for "-W*" options together with CL_C and/or CL_CXX (ok, there is also -Wall and -Wextra, but hopefully we don't emit [Wall] or [Wextra] for anything). 2020-05-04 Jakub Jelinek <jakub@redhat.com> * opts.c (get_option_html_page): Instead of hardcoding a list of options common between C/C++ and Fortran only use gfortran/ documentation for warnings that have CL_Fortran set but not CL_C or CL_CXX.
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.
