[PATCH] D54747: Discard debuginfo for object files empty after GC

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added inline comments.


================
Comment at: lld/ELF/MarkLive.cpp:190
 
+template <class ELFT> static void setSectionLive(InputSectionBase *Sec) {
+  Sec->Live = true;
----------------
Since this file is MarkLive, markSection is perhaps a better name.


================
Comment at: lld/ELF/MarkLive.cpp:192
+  Sec->Live = true;
+  if (Sec->kind() != SectionBase::Kind::Regular &&
+      Sec->kind() != SectionBase::Kind::Merge)
----------------

This needs a comment.

Do you have to visit each file during the mark phase? Looks like you can mark only sections first, and after marking all sections, you can scan all sections to mark files. Looks like they can be two separate stages.
