Optimise your binaries for real-world workloads.
Guides creation of optimised binaries by collecting representative workload profiles and using them in subsequent builds.
When to use it
Use when standard optimisation has plateaued, when implementing profile-guided builds, or when applying BOLT post-link optimisation.
Give it a project to optimise; it guides instrumented builds, representative workload runs, profile collection, and an optimised build.
What you provide
Uses perf to compare baseline and PGO performance and inspect hot functions during verification.
Enables the additional post-link optimisation stage, which can follow PGO.
