The gold LTO plugin uses a set of hooks to implements emit-llvm and capture intermediate file generated during LTO. The hooks are called by each lto backend thread with a taskID as argument to differentiate between threads and tasks. Currently, all threads are overwriting the same file which results into only the intermediate output of the last backend thread to be preserved. This diff encodes the taskID into the filename.

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.
