Reid Kleckner 8577eaf8e6 GlobalOpt: Preserve comdats of unoptimized initializers ... Rather than slurping in and splatting out the whole ctor list, preserve the existing array entries without trying to understand them. Only remove the entries that we know we can optimize away. This way we don't need to wire through priority and comdats or anything else we might add. Fixes a linker issue where the .init_array or .ctors entry would point to discarded initialization code if the comdat group from the TU with the faulty global_ctors entry was dropped. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218337 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-23 22:33:01 +00:00
