Adding a new option to CMake to disable C++ atexit on llvm-shlib.

Authored by beanz on Dec 8 2014, 2:25 PM.



This is desirable for WebKit and other clients of the llvm-shlib because C++ exit time destructors have a tendency to crash when invoked from multi-threaded applications.

Ideally this option will be temporary, because the ideal fix is to just not have exit time destructors.

How many atexit dtors do we have still? How long do you think this will stay?

Given that we had such a struggle with the other symbol override in, I'm surprised you went this route. :)
