Teresa Johnson 3b11c8e6e3 Add new EliminateAvailableExternally module pass, which is performed in ... O2 compiles just before GlobalDCE, unless we are preparing for LTO. This pass eliminates available externally globals (turning them into declarations), regardless of whether they are dead/unreferenced, since we are guaranteed to have a copy available elsewhere at link time. This enables additional opportunities for GlobalDCE. If we are preparing for LTO (e.g. a -flto -c compile), the pass is not included as we want to preserve available externally functions for possible link time inlining. The FE indicates whether we are doing an -flto compile via the new PrepareForLTO flag on the PassManagerBuilder. llvm-svn: 239480		2015-06-10 17:49:28 +00:00
