fortran: Drop -static-lib{gfortran,quadmath} from f951 [PR46539]
As discussed earlier, all other -static-lib* options are Driver only,
these 2 are Driver in common.opt and Fortran in lang.opt.
The spec files never pass the -static-lib* options down to any compiler
(f951 etc.), so the 2 errors below are reported only when one
runs ./f951 -static-libgfortran by hand.
The following patch just removes f951 support of these options, the
gfortran driver behavior remains as before. For other -static-lib*
option (and even these because it is never passed to f951) we never
error if we can't support those options, and e.g. Darwin is actually
able to handle those options through other means.

* lang.opt (static-libgfortran, static-libquadmath): Change Fortran
to Driver.
* options.cc (gfc_handle_option): Don't handle
OPT_static_libgfortran
nor OPT_static_libquadmath here.

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 Jakub Jelinek 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.

After reading posts about it and looking at otool -L, it seems like this is what is needed.

Work arounds: You could try to link with "gcc" rather than with gfortran, but you then need to explicitly include the gfortran, quadmath and m(ath) library: gcc -static-libgcc -Wl,-Bstatic -lstdc++ -lgfortran -lquadmath -Wl,-Bdynamic -lm as that avoids "gfortran"'s special treatment of libquadmath. [You might consider to add -Wl,--as-needed ... -Wl,--no-as-needed. That avoids linking files when they are not needed.] An alternative is to modify libgfortran.spec - and add there the "-Bstatic" ... "-Bdynamic" unconditionally. Or you create your own .spec file and load it via -specs= (The "libgfortran.spec" file is a text file in the installed GCC tree; e.g. it could be /lib*/libgfortran.spec. If you use GCC/gfortran with "-v" the output should inform you about which file has been read - and how the linker is called.)

For the application I am dealing with, I need to link statically the compiler provided libraries while linking dynamically the system ones (pthread, mpi, etc.). Linking with "gfortran -static-libgfortran -static-libgcc -Wl,-Bstatic -lstdc++ -Wl,-Bdynamic" solves the problem except for "libquadmath.so.0". Linking with "-Wl,-Bstatic -lquadmath -Wl,-Bdynamic" does not help. The only workaround I found is to configure gcc with "configure --disable-libquadmath-support". Could you please implement "-static-libquadmath" or make "-Wl,-Bstatic -lquadmath -Wl,-Bdynamic" work?
