Inline Expansion: Compiler Optimization, Called Party, Branch (computer science), Algorithmic Efficiency, Return Statement, CPU Cache, Constant (programming), Compiler, Copy and Paste Programming.

In computing, inline expansion, or inlining, is a manual or compiler optimization that replaces a function call site with the body of the callee. This optimization may improve time and space usage at runtime, at the possible cost of increasing the final size of the program (i.e. the binary file size).
