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

--- Comment #14 from LoneVVolf  ---
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.

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

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.

--- Comment #7 from LoneVVolf lonew...@xs4all.nl ---
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.
