[Jacek Caban via Phabricator via llvm-commits]

jacek added inline comments.


================
Comment at: llvm/lib/Object/ArchiveWriter.cpp:769
+  // COFF symbol map uses 16-bit indexes, so we can't use it if there are too
+  // many members.
+  if (isCOFFArchive(Kind) && NewMembers.size() > 0xfffe)

According to my testing, it has a limit of 4090 object files. When I try to pass more, I get an ambiguous error:
$ lib -out:test.lib -nologo @inputs/files.txt
LINK : fatal error LNK1104: cannot open file 'inputs\a4091.obj'
