llvmGCC Link Time Optimization: Architecture Note for Cross-Module Optimization
Architecture note on GCC LTO: requirements, minimal GIMPLE/linker-plugin design, version-locked trust boundaries, operational checks, failure modes (OOM, miscompilation), and design-change triggers (incremental LTO, C++20 modules).
Boosting GCC Builds with Link‑Time Optimization (LTO): How, Why, and What to Watch For
Learn how GCC’s Link‑Time Optimization (LTO) can shrink binaries and boost speed. Enable it with -flto, understand the IR‑based pipeline, see a worked two‑file example, and avoid common pitfalls like memory spikes and symbol stripping.
Using GCC Link-Time Optimization to Shrink and Speed Up Your C Programs
Learn how GCC’s Link-Time Optimization (-flto) enables whole-program inlining and dead-code elimination, reducing binary size and improving runtime, along with its trade-offs and verification steps.
cGCC Link-Time Optimization: Architecture Note
An architecture note on GCC Link-Time Optimization: requirements, minimal design, trust/data boundaries, operational checks, failure modes, and conditions that would change the design.
Full LTO vs ThinLTO: Choosing an LLVM Link-Time Optimization Mode
A decision guide for adding LTO to a Clang/LLVM build: compare Full LTO and ThinLTO, check constraints and trade-offs, and validate with concrete commands.
Diagnosing LLVM AddressSanitizer False Positives at -O2 and Higher
Diagnose LLVM AddressSanitizer false positives that appear only at -O2 or higher, with steps to distinguish optimization artifacts from real memory errors.
Diagnosing GCC Link-Time Optimization (LTO) Symbol Visibility & Resolution Failures
A diagnostic guide for GCC 7–13 Link-Time Optimization failures: recognize undefined reference and multiple definition errors, trace root causes through symbol visibility, ODR flag mismatches, and mixed LTO/non-LTO objects, then apply targeted fixes with version-aware commands.
Diagnosing and Fixing Common LLVM Link‑Time Optimization (LTO) Link Errors
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.
