yes, the patch in comment #5 solves the problem.

Looking at the 'bad' commit, it seems the changes in 
src/gallium/auxiliary/Makefile.am required a change in the 
src/gallium/drivers/radeon/Makefile.am ?

If so, i wonder if other drivers then radeon are affected also.
The patch looks more as a workaround then as a real solution.

This seems less than ideal, as it makes libllvmradeon duplicate lots of stuff
from the driver *.so, and it grows from ~500K to ~10M for me.

That appears to be correct,
in a git version build on march 11
libllvmradeon9.2.0.so is just 39 Kib .
Build with the patch it's size increases to 1.8 Mib !

Hmm we definitely need a shared libgallium.
That would reduce the size of all gallium drivers.

Or we could remove/revert the visibility flags from
src/gallium/auxiliary/Makefile.am

--- Comment #14 from LoneVVolf <lonewolf@xs4all.nl> ---
Trying to summarize

I've looked a bit more at bug #59238, and if i understand correctly the problem
with building xa tracker was that symbols were exported that are not supposed
to be visible outside of the library itself ?

By adding the VISIBILITY_CFLAGS and VISIBILITY_CXXFLAGS changes in the f70c385
commit, the troublesome symbols were removed.
A consequence however was that symbols needed for r600_dri.so to call
libllvmradeon9.2.0.so were no longer present.

Including $(top_builddir)/src/gallium/auxiliary/libgallium.la in
src/gallium/drivers/radeon/Makefile.am makes sure all needed symbols are
present, but has a size increase of libllvmradeon9.2.0 as downside.

To counter the size increase, switching to a shared libgallium is proposed.

The size increase only happens if radeonsi is built too, and can be countered
with the shared libgallium patch.

The original bug described here is fixed with these 2 commits:

36320bfa54b758b34 - radeon/llvm: Link against libgallium.la to fix an undefined
symbol
7c3d8301afed46cf9 - radeon/llvm: Do not link against libgallium when building
statically.
