The following patch is a revival of the https://gcc.gnu.org/legacy-ml/gcc-patches/2014-10/msg00771.html patch. While trunk configured against recent glibc and with linker --as-needed support doesn't really need to link against -lquadmath anymore, there are still other targets where libquadmath is still in use. As has been discussed, making -static-libgfortran imply statically linking both libgfortran and libquadmath is undesirable because of the significant licensing differences between the 2 libraries. Compared to the 2014 patch, this one doesn't handle -lquadmath addition in the driver, which to me looks incorrect, libgfortran configure determines where in libgfortran.spec -lquadmath should be present if at all and with what it should be wrapped, but analyzes gfortran -### -static-libgfortran stderr and based on that figures out what gcc/configure.ac determined. 2022-08-17 Francois-Xavier Coudert <fxcoudert@gcc.gnu.org> Jakub Jelinek <jakub@redhat.com> PR fortran/46539 gcc/ * common.opt (static-libquadmath): New option. * gcc.cc (driver_handle_option): Always accept -static-libquadmath. * config/darwin.h (LINK_SPEC): Handle -static-libquadmath. gcc/fortran/ * lang.opt (static-libquadmath): New option. * invoke.texi (-static-libquadmath): Document it. * options.cc (gfc_handle_option): Error out if -static-libquadmath is passed but we do not support it. libgfortran/ * acinclude.m4 (LIBQUADSPEC): From $FC -static-libgfortran -### output determine -Bstatic/-Bdynamic, -bstatic/-bdynamic, -aarchive_shared/-adefault linker support or Darwin remapping of -lgfortran to libgfortran.a%s and use that around or instead of -lquadmath in LIBQUADSPEC. * configure: Regenerated.

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.
