Trouble finding the definition for class BarrierSet

I am currently looking at JDK-8203787 again, the problem still exists (see below).

What I don't understand: Why is class BarrierSet apparently not declared in this
case. I tried understanding the logic through which "barrierSet.hpp" ends up
being included in library_call.cpp but I cannot find anything, the level
of nesting is just too deep to be able to follow all transitive #include

Does anyone have an idea how to be able to track this down? Does Solaris do
anything special with regards to "class BarrierSet" or is there a "os_cpu"-
specific implementation/include etc?

There must be a trivial bug on linux-sparc which prevents "class BarrierSet"
from being defined here but I can't seem to see the problem.
