Rafael Espindola dfc7ed7ad0 gold plugin: Handle gold selecting a linkonce GV when a weak is present. The plugin API doesn't have the notion of linkonce, only weak. It is up to the plugin to figure out if a symbol used only for the symbol table can be dropped. In particular, it has to avoid dropping a linkonce_odr selected by gold if there is also a weak_odr. llvm-svn: 219188		2014-10-07 04:06:13 +00:00

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.
