Michael, all,

Regarding:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101766
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102110

If I understand correctly, since the GCC MicroBlaze targets generate ELF
images, it would seem there's no technical reason why `__attribute__
((symver ...))` cannot be supported?

The issue seems to be that the MicroBlaze targets in config.gcc do not
include elfos.h
https://github.com/gcc-mirror/gcc/blob/master/gcc/config.gcc#L2369

Which defines `ASM_OUTPUT_SYMVER_DIRECTIVE`
https://github.com/gcc-mirror/gcc/blob/master/gcc/config/elfos.h#L259

Which is necessary for
https://github.com/gcc-mirror/gcc/blob/master/gcc/varasm.cc#L6260

Changing the targets to include elfos.h leads to a number of conflicts with
the target specific header (config/microblaze/microblaze.h).

Should `ASM_OUTPUT_SYMVER_DIRECTIVE` be copied into
config/microblaze/microblaze.h or should the MicroBlaze targets and header
be reworked to support elfos.h?

I'm asking because I've seen a number of projects run into this issue (xz,
elfutils, libfuse, libkcapi, cryptsetup).

Thanks,
-Vincent
