Extracted from the Wikipedia article Interprocedural optimization.
WPO and LTO
Link-time optimization (LTO) is a type of program optimization performed by a compiler to a program at link time. Link time optimization is relevant in programming languages that compile programs on a file-by-file basis, and then link those files together (such as C and Fortran), rather than all at once (such as Java's just-in-time compilation (JIT)).
