[Lldb-commits] [PATCH] D47708: PDB support of function-level linking and splitted functions

[Zachary Turner via lldb-commits]

As a general rule, lld-link is command line compatible with MSVC and
clang-cl is command line compatible with cl.  So, the /order option should
work exactly the same with lld-link as it does with link.
