Optimization Level - CI/CD Glossary Definition
Optimization level is a compiler flag that trades build time and debuggability for faster or smaller output code.
An optimization level is a compiler setting (for example -O0 through -O3, or -Os for size) that trades build time and debuggability against the speed and size of the generated code.

In CI
Use a low level (-O0 or -Og) for CI test builds to compile fast and keep debug info accurate; use a high level (-O2, -O3) for the release build. Optimized builds can expose undefined behavior that debug builds hide, so test both when it matters.
