The LTO opt level should not affect the codegen opt level, and indeed it does not affect it in lld. Ideally the codegen opt level should be controlled by an IR-level attribute based on the compile-time opt level, but that hasn't been implemented yet.

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.
