; There are two main cases where comdats are necessary:
|

; 1. standard inline functions (weak_odr / linkonce_odr)
|
||||
; 2. available externally functions (C99 inline / extern template / dllimport)
|
||||
; Check that we do the right thing for the two object formats with comdats, ELF

; and COFF.
