The complicated situation is when we have to keep an alias but drop a GV that is part of the aliasee. We used to clone the dropped GV and make the clone internal. This is wasteful as we know the original will be dropped. With this patch what is done instead is set the linkage of the original to internal and replace all uses (but the one in the alias) with a new declaration that takes the name of the old GV. This saves us from having to copy the body. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223863 91177308-0d34-0410-b5e6-96231b3b80d8 |

The LLVM Gold LTO Plugin ======================== This directory contains a plugin that is designed to work with binutils gold linker. At present time, this is not the default linker in binutils, and the default build of gold does not support plugins. See docs/GoldPlugin.html for complete build and usage instructions. NOTE: libLTO and LLVMgold aren't built without PIC because they would fail to link on x86-64 with a relocation error: PIC and non-PIC can't be combined. As an alternative to passing --enable-pic, you can use 'make ENABLE_PIC=1' in your entire LLVM build.
