Teresa Johnson b907d06151 [ThinLTO/gold] Enable symbol resolution in distributed backend case While testing a follow-on change to enable index-based symbol resolution and internalization in the distributed backends, I realized that a test case change I made in r275247 was only required because we were not analyzing symbols in the claimed files in thinlto-index-only mode. In the fixed test case there should be no internalization because we are linking in -shared mode, so f() is in fact exported, which is detected properly when we analyze symbols in thinlto-index-only mode. Note that this is not (yet) a correctness issue (because we are not yet performing the index-based linkage optimizations in the distributed backends - that's coming in a follow-on patch). llvm-svn: 275277		2016-07-13 16:35:56 +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.
