static inline functions disappear - incorrect static initialiser analysis?

-fno-unit-at-a-time might help.  This disables some of the cgraph 
optimizations.  This will probably go away eventually.

No.  cgraph should determine by itself that the function is needed.  The 
assemble_name call shouldn't be relevant here.

I think this is referring to use of __asm__ to change the name of a 
function in unexpected ways.  It doesn't have anything to do with your 
problem.

What you should do here is pick a target that works, and debug cgraph to 
see how it works.  Then debug your target to see why it doesn't.

The sequence of events should be something like:
1) We walk the tree for main, and note that main calls fn.
2) We emit main because it is extern.
3) We then emit everything that main calls, which includes fn.

I won't hazard a guess as to what is wrong, as I don't see how this 
could be failing.
