Inline function expansion replaces a function call with the function body. With automatic inline function expansion, programs can be constructed with many small functions to handle complexity and then rely on the compilation to eliminate most of the function calls. Therefore, inline expansion serves a tool for satisfying two conflicting goals: minizing the complexity of the program development and minimizing the function call overhead of program execution. A simple inline expansion procedure is

Experiments show that a large percentage of function calls/returns (about 59%) can be eliminated with a modest code expansion cost (about 17%) for twelve UNIX* programs.
