twoh added a comment. @joerg Sorry but I'm not sure if I understand your question. This doesn't pretend to honor source code order, but makes linker to place "hot" functions under .text.hot section (There's no guarantee of ordering between functions inside .hot.text section) while "cold" functions under .text.unlikely section. This is purely for performance.
