Let me add that there's another class of problems with toplevel asms and LTO:
as a result of LTO partitioning, toplevel asm may be moved into a different
partition from the symbol it's referencing, breaking the build (when toplevel
asm is referencing a static function). GCC bug report for that issue is here:
