Comment # 1 on bug 76082 from Ilia Mirkin

Hrmph. I guess it's not as harmless as I thought!

Can you provide the output of

llvm-config --ldflags (for the llvm-config that mesa uses)
llvm-config --libdir

readelf -d /path/to/r600_dri.so (or radeonsi_dri.so, not sure which one you
have)

ldd /path/to/r600_dri.so

The latter 2 for both good and bad versions.
