--- Comment #79 from Cary Coutant <ccoutant at gcc dot gnu.org> 2012-04-17 18:00:41 UTC --- (In reply to comment #77) > I believe .init_array keeps the same order of .ctors within > the same translation unit.

If you have translation unit A with .ctors entries A1 and A2, and translation unit B with .ctors entries B1 and B2, we'll build a .init_array section with: B1 B2 A1 A2 As Paul noted, this is a moot point in practice for .ctors, since GCC emits only a single .ctors entry per TU, but it could be significant for assembly code or for TUs with .init_array sections. -cary
