down to pass builder in ltobackend. Currently CodeGenOpts like UnrollLoops/VectorizeLoop/VectorizeSLP in clang are not passed down to pass builder in ltobackend when new pass manager is used. This is inconsistent with the behavior when new pass manager is used and thinlto is not used. Such inconsistency causes slp vectorization pass not being enabled in ltobackend for O3 + thinlto right now. This patch fixes that. Differential Revision: https://reviews.llvm.org/D72386 |

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.
