--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> --- (In reply to Fangrui Song from comment #3) > > I don't know what happened to the 2010-01 patch. It likely did not let > __start_ reference retain magic sections in other translation unit (in > metadata section usage __start_/__stop_ references are always in a separate > runtime file), so "__start_ retaining all magic sections" was not effective > before 2015-10. Why do we need new start/stop symbols? The orphan > __start_/__stop_ usage worked before 2015-10 and will work with -z > start-stop-gc. You got it wrong. --gc-section never worked correctly before all these fixed applied. > (I think of the possibility enabling -z start-stop-gc by default because the > rule was essentially invalid before 2015-10.) > LLVM requires a different __start_/__stop_ semantic, which isn't wrong by itself. But it shouldn't hijack the current one. -- You are receiving this mail because: You are on the CC list for the bug.
