> Merged into LLVM's mono repository minutes ago was BOLT! This is the Facebook-developed tool for optimizing the layout of binaries in the name of delivering greater performance

" Facebook for their data center usage of BOLT reports, " _For datacenter applications, BOLT achieves up to 7.0% performance speedups on top of profile-guided function reordering and LTO. For the GCC and Clang compilers, our evaluation shows that BOLT speeds up their binaries by up to 20.4% on top of FDO and LTO, and up to 52.1% if the binaries are built without FDO and LTO._ “”
