Teresa Johnson f2b5ec6ef4 [ThinLTO] Keep common symbols in ThinLTO modules Summary: Skip the merging of common symbols for ThinLTO modules, they will be merged by the final native object link. Trying to merge the symbols and add to a combined module will incorrectly enable the common symbol to be internalized in the ThinLTO module. Additionally, we will not want to create a combined module for ThinLTO distributed builds. This fixes failures in 7 cpu2006 benchmarks from the new LTO API in ThinLTO mode.

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.
