Feedback‑Driven Compiler Optimizations for Cloud C/C++ Applications

The article shows how profiling‑driven compiler and OS techniques—such as sampling and instrumentation PGO, BOLT code layout, AutoFDO pipelines, basic‑block reordering, partial inlining, branch and function reordering—can alleviate instruction‑cache and front‑end stalls in large C/C++ cloud workloads, delivering up to 18 % performance gains.
