Indeed, the execution path data it provides helps the compiler to generate better code and better cacheline packing.\n  At the time of this writing, compilers only support instrumentation-based PGO. This proved effective for optimizing programs. However, few projects use it, due to its complicated dual-compilation model and its high overhead. Our solution of sampling Hardware Performance Counters overcome these drawbacks. In this paper, we propose a PGO solution for GCC by sampling Last Bra","authors_text":"Baptiste Wicht, David Levinthal, Dehao Chen, Roberto A.
