--- Comment #11 from Fangrui Song <i at maskray.me> ---
LangRef has been clarified by https://reviews.llvm.org/D106300

Due to https://sourceware.org/bugzilla/show_bug.cgi?id=28124#c1 , unfortunately
we cannot use SHF_LINK_ORDER to represent the semantics of the third field of
llvm.global_ctors 

Therefore, on ELF we are stuck with section groups. We therefore have the
limitation:

  On ELF the referenced global variable or function must be in a comdat.

So the original report is unsupported.
