Peter Collingbourne 80186a57d6 LTO: Simplify caching interface. The NativeObjectOutput class has a design problem: it mixes up the caching policy with the interface for output streams, which makes the client-side code hard to follow and would for example make it harder to replace the cache implementation in an arbitrary client. This change separates the two aspects by moving the caching policy to a separate field in Config, replacing NativeObjectOutput with a NativeObjectStream class which only deals with streams and does not need to be overridden by most clients and introducing an AddFile callback for adding files (e.g. from the cache) to the link.

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.
