Re: static inline functions disappear - incorrect static initialiser analysis?

This no longer appears to be the case? `assemble_name' is still called with `fn', and correctly marks `fn' as being referenced, but no body is ever emitted.

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


Do I now need to do something more than just calling assemble_name to get gcc to output the function body in such a case?

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


 /* ??? If the assembler name is set by hand, it is possible to assemble
    the name later after finalizing the function and the fact is noticed
    in assemble_name then.  This is arguably a bug.  */

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.
