Stop letting the linker stall your CI. Learn how LLVM ThinLTO parallelizes the link step to reduce build times from 15 minutes to under 3 minutes for large C++ projects.
When LLVM’s LTO produces link failures, the culprit is often a mismatch in flags, libraries, or linker support. This guide walks through a concise cause‑effect table, ordered checks, and targeted fixes so you can restore a successful LTO build.
ThinLTO balances compile‑time speed and runtime performance by generating compact summaries during compilation and performing global optimizations in parallel, reducing link time by up to 70% while still delivering most of the benefits of full LTO.
A concise guide to creating a minimal LLVM New Pass Manager pass, covering requirements, the smallest workable design, trust boundaries, operational checks, failure modes, and verification steps.
