Summary: Launch ThinLTO backends (LTO and codegen pipelines with importing) in parallel using a ThreadPool, after creating the combined index. The number of threads is controlled by the existing -jobs gold plugin option, or the hardware concurrency if not specified. The old behavior of exiting after creating the combined index can be invoked via a new thinlto-index-only plugin option. This commit involves just the ThinLTO-specific pieces of D15390, the NFC and other restructuring pieces were committed independently: r262677: Add hardware_concurrency interface to llvm::thread (NFC) r262719: Change split code gen to use ThreadPool r262721: Refactor gold-plugin codegen to prepare for ThinLTO threads (NFC) Reviewers: pcc, joker.eph, rafael Subscribers: rafael, davidxl, llvm-commits, joker.eph Differential Revision: http://reviews.llvm.org/D15390 llvm-svn: 262724 |
